Melioidosis is caused by Burkholderia pseudomallei and is an important zoonotic infectious disease causing high mortality from fulminant septicaemia in humans and a wide variety of animal species. The incidence of fatal melioidosis in zoo animals has been significant in many Thai zoos. A total number of 32 cases were evaluated throughout the Thai zoo animal populations. The highest prevalence of disease has been reported from the north-eastern region followed by the zoos in the southern part of the country, approximately 47% and 38%, respectively, while the other zoos reported sporadic infections. Herbivores and non-human primates were the most commonly affected animals with incidences of 59% and 28%, respectively. This appears to be a seasonal correlation with the highest incidence of melioidosis in zoo animals reported in the rainy season (44%) or subdivided monthly in June (19%) followed by September and November (16% and 12%, respectively). The route of infection and the incubation period still remain unclear. This retrospective study examined the clinical presentation in various zoo species, pathological findings and epidemiological data as well as conducting an in depth literature review. © 2015 Blackwell Verlag GmbH.

The Assessment of Animal Welfare in British Zoos by Government-Appointed Inspectors.

PubMed

Draper, Chris; Harris, Stephen

2012-09-28

We analysed the reports of government-appointed inspectors from 192 zoos between 2005-2008 to provide the first review of how animal welfare was assessed in British zoos since the enactment of the Zoo Licensing Act 1981. We examined the effects of whether or not a veterinarian was included in the inspection team, type of inspection, licence status of the zoo and membership of a zoo association on the inspectors' assessments of animal welfare standards in five areas that approximate to the Five Freedoms. At least 11% of full licence inspections did not comply with the legal requirement for two inspectors. The inspectors' reports were unclear as to how animal welfare was assessed, whether all animals or only a sub-sample had been inspected, and were based predominantly on welfare inputs rather than outcomes. Of 9,024 animal welfare assessments across the 192 zoos, 7,511 (83%) were graded as meeting the standards, 782 (9%) as substandard and the rest were not graded. Of the 192 zoos, 47 (24%) were assessed as meeting all the animal welfare standards. Membership of a zoo association was not associated with a higher overall assessment of animal welfare standards, and specialist collections such as Farm Parks and Other Bird collections performed least well. We recommend a number of changes to the inspection process that should lead to greater clarity in the assessment of animal welfare in British zoos.

Are we ignoring neutral and negative human-animal relationships in zoos?

PubMed

Hosey, Geoff; Melfi, Vicky

Human-animal interactions (HAI), which may lead to human-animal relationships (HAR), may be positive, neutral, or negative in nature. Zoo studies show that visitors may be stressful, may have no effect, or may be enriching. There is also evidence that good HARs set up between animals and their keepers can have positive effects on animal welfare. However, we need to know more about negative HARs, and as a first step we attempt to do this here by considering cases where animals attack people in the zoo. Due to the sensitivity and rarity of these events data appear sparse and unsystematically collected. Here, information available in the public domain about the circumstances of these attacks has been collated to test hypotheses about negative HAIs derived from a model of zoo HARs. The limited data presented here broadly support the zoo HAR model, and suggest that attacks usually happen in unusual circumstances, where there may be a failure by the animal to recognise the HAR, or where the relationship, if there is one, does not hold; and give some support to the prediction that exposure to many keepers may impair the development of a positive HAR. This study may provide useful information for the zoo community to proactively collect systematic standardised records, which will enable a fuller understanding of zoo HARs, upon which appropriate measures might be adopted to build better zoo HARs, which are likely to positively impact zoo animal welfare, and reduce these rare incidences further. © 2014 Wiley Periodicals, Inc.

Measuring zoo animal welfare: theory and practice.

PubMed

Hill, Sonya P; Broom, Donald M

2009-11-01

The assessment of animal welfare relates to investigations of how animals try to cope with their environment, and how easy or how difficult it is for them to do so. The use of rigorous scientific methods to assess this has grown over the past few decades, and so our understanding of the needs of animals has improved during this time. Much of the work in the field of animal welfare has been conducted on farm animals, but it is important to consider how the methods and approaches used in assessing farm animal welfare have been, and can be, adapted and applied to the measurement of welfare in animals in other domains, such as in zoos. This is beneficial to our understanding of both the theoretical knowledge, and the practicability of methods. In this article, some of the commonly-used methods for measuring animal welfare will be discussed, as well as some practical considerations in assessing the welfare of zoo animals.

Visitor interest in zoo animals and the implications for collection planning and zoo education programmes.

PubMed

Moss, Andrew; Esson, Maggie

2010-01-01

As zoos have sought to further their conservation missions, they have become powerful providers of environmental education. Outside of "formal" education initiatives, such as those designed for school and other organized groups, or structured public talks programmes, much of the learning potential that the zoo has to offer is around the viewing of animals and the response of visitors to them. In this, zoo learning is a very personal construct, develops from the previous knowledge, and experiences and motivations of each individual. In this article, we make the assertion that learning potential, although difficult to quantify, is very much related to the attractiveness of animal species and the interest that visitors show in them. Using standard behaviorist measures of attraction and interest (the proportion of visitors that stop and for how long), we analyzed the relative interest in 40 zoo species held in a modern UK zoo and the variables that are significant in predicting that popularity. Further to this, the suggestion is made that the zoo collection planning process could use such information to make more informed decisions about which species should be housed for their educational value. Taxonomic grouping was found to be the most significant predictor of visitor interest--that is, visitors were far more interested in mammals than any other group--although body size (length), increasing animal activity and whether the species was the primary or "flagship" species in an exhibit or not, were all found to have a significant bearing on visitor interest. © 2010 Wiley-Liss, Inc.

Bioaugmentation of the anaerobic digestion of food waste by dungs of herbivore, carnivore, and omnivore zoo animals.

The potential improvement of biomethanation of food waste (FW) by adding dung of herbivore (giraffe, llama, koala), carnivore (tiger), and omnivore (sloth bear) animals to anaerobic sludge (AnS) was investigated. Adding 30% giraffe, sloth bear or koala dung to the AnS inoculum yielded, respectively, a 11.17 (±4.51), 10.10 (±1.23), and 1.41 (±0.56)% higher biomethane production, as compared to the control (FW with solely AnS). The highest biomethane production of 564.00 (±3.88) ml CH 4 /gVS added obtained with 30% giraffe dung and 70% AnS was attributed to a higher solubilization of proteins (6.96 ± 2.76%) and recalcitrant carbohydrates (344.85 ± 54.31 mg/L as compared to zero). The biomethanation process could have been stimulated by the microorganisms or enzymes newly introduced, and/or the trace elements (Ni, Zn, and Co) present in the giraffe dung. These results indicate that bioaugmentation with zoo animals dung is worthy of further investigation as a strategy for improving the biomethane recovery from organic wastes.

Measuring animal personality for use in population management in zoos: suggested methods and rationale.

PubMed

Watters, Jason V; Powell, David M

2012-01-01

The concept that animals have personalities is gaining traction in the scientific community and is well established in zoos and aquariums. Applying knowledge of animal personalities has occurred more slowly and is most often only considered informally. However, animal personalities are likely to affect the welfare animals experience in captivity and thus should be of primary concern to zoo managers. In addition, animal personality likely affects the outcomes of zoo guest experiences and potentially guests' conservation-related behavior. With over 1,000,000 animals in the care of zoos internationally and hundreds of millions of visitors annually, it would be prudent and beneficial to maximize our use of animal personality data in zoos to effect positive conservation outcomes. Understanding how to broaden population planning techniques to include measures of animal personality and the important outcomes of welfare and education value is of prime importance to the zoo industry. In order to succeed, it is necessary to employ techniques that reliably assess animal personalities and provide measures that can easily be used in population planning models. We discuss the outcomes of recent workshops designed to determine the best techniques for measuring animal personalities in the zoo setting with the goal of incorporating personality into population planning. © 2011 Wiley Periodicals, Inc.

Salmonellosis is an important zoonotic disease but little is known about the role that free-living animals play as carriers of this pathogen. Moreover, the primary route of infection in the wild needs to be elucidated. The aim of this study was to determine the source and the route of transmission of Salmonella enterica serovar Albany (S. Albany) infection in captive zoo wild animals in the Culiacán Zoo. A total of 267 samples were analyzed including 220 fecal samples from zoo animals, 15 fecal samples from rodents, 5 pooled samples each of two insects (Musca domestica and Periplaneta americana), and 22 samples of animal feed. We detected S. Albany in 28 (10.5%) of the samples analyzed, including in samples from raw chicken meat. Characterization of isolates was performed by serotyping and pulsed-field gel electrophoresis. All isolates shared a single pulsed-field gel electrophoresis profile, indicating a possible common origin. These data suggest that the infected meat consumed by the wild felines was the primary source of infection in this zoo. It is likely that the pathogen was shed in the feces and disseminated by insects and rats to other locations in the zoo.

Do Formal Inspections Ensure that British Zoos Meet and Improve on Minimum Animal Welfare Standards?

PubMed Central

Draper, Chris; Browne, William; Harris, Stephen

2013-01-01

Simple Summary Key aims of the formal inspections of British zoos are to assess compliance with minimum standards of animal welfare and promote improvements in animal care and husbandry. We compared reports from two consecutive inspections of 136 British zoos to see whether these goals were being achieved. Most zoos did not meet all the minimum animal welfare standards and there was no clear evidence of improving levels of compliance with standards associated with the Zoo Licensing Act 1981. The current system of licensing and inspection does not ensure that British zoos meet and maintain, let alone exceed, the minimum animal welfare standards. Abstract We analysed two consecutive inspection reports for each of 136 British zoos made by government-appointed inspectors between 2005 and 2011 to assess how well British zoos were complying with minimum animal welfare standards; median interval between inspections was 1,107 days. There was no conclusive evidence for overall improvements in the levels of compliance by British zoos. Having the same zoo inspector at both inspections affected the outcome of an inspection; animal welfare criteria were more likely to be assessed as unchanged if the same inspector was present on both inspections. This, and erratic decisions as to whether a criterion applied to a particular zoo, suggest inconsistency in assessments between inspectors. Zoos that were members of a professional association (BIAZA) did not differ significantly from non-members in the overall number of criteria assessed as substandard at the second inspection but were more likely to meet the standards on both inspections and less likely to have criteria remaining substandard. Lack of consistency between inspectors, and the high proportion of zoos failing to meet minimum animal welfare standards nearly thirty years after the Zoo Licensing Act came into force, suggest that the current system of licensing and inspection is not meeting key objectives and requires

Neospora caninum is an apicomplexan parasite that causes neuromuscular disease in dogs and abortions in cattle. Little is known about the prevalence of antibodies to this parasite in zoo animals. Sera from 556 animals, from 13 Czech and Slovak zoos were tested for antibodies to N. caninum and Toxoplasma gondii by indirect fluorescent antibody test. Antibodies to N. caninum were found in 31 of 556 zoo animals (5.6%), representing 18 of 114 species tested: Eurasian wolf (Canis lupus lupus), Maned wolf (Chrysocyon brachyurus), fennec (Vulpes zerda), cheetah (Acinonyx jubatus), jaguarundi (Herpailurus yaguarondi), Eurasian lynx (Lynx lynx), Indian lion (Panthera leo goojratensis), fisher (Martes pennanti), blackbuck (Antilope cervicapra), European bison (Bison bonasus), lechwe (Kobus leche), African buffalo (Syncerus caffer caffer), eland (Taurotragus oryx), sitatunga (Tragelaphus spekei gratus), Thorold's deer (Cervus albirostris), Eastern elk (C. elaphus canadensis), Vietnam sika deer (C. nippon pseudaxis) and Père David's deer (Elaphurus davidianus). Titres ranged from 1:40 to 1:2560. The highest prevalence 50% was found in family mustelidae of the order carnivora. Antibodies to T. gondii were detected in 193 of 556 zoo animals (34.7%) representing 72 of 114 species tested, with titres ranging from 1:40 to 1:40960. The highest prevalence 100% was found in families: hyaenidae, mustelidae, ursidae and viveridae of the order carnivora. The results of this study indicate that zoo animals have more exposure to T. gondii than to N. caninum. It is the first report of seroprevalence of antibodies to N. caninum in European zoo animals.

Seroepidemiology of Toxoplasma gondii in zoo animals in selected zoos in the midwestern United States.

de Camps, Silvia; Dubey, J P; Saville, W J A

2008-06-01

Toxoplasma gondii infections in zoo animals are of interest because many captive animals die of clinical toxoplasmosis and because of the potential risk of exposure of children and elderly to T. gondii oocysts excreted by cats in the zoos. Seroprevalence of T. gondii antibodies in wild zoo felids, highly susceptible zoo species, and feral cats from 8 zoos of the midwestern United States was determined by using the modified agglutination test (MAT). A titer of 1:25 was considered indicative of T. gondii exposure. Among wild felids, antibodies to T. gondii were found in 6 (27.3%) of 22 cheetahs (Acynonyx jubatus jubatus), 2 of 4 African lynx (Caracal caracal), 1 of 7 clouded leopards (Neofelis nebulosa), 1 of 5 Pallas cats (Otocolobus manul), 12 (54.5%) of 22 African lions (Panthera leo), 1 of 1 jaguar (Panthera onca), 1 of 1 Amur leopard (Panthera pardus orientalis), 1 of 1 Persian leopard (Panthera pardus saxicolor), 5 (27.8%) of 18 Amur tigers (Panthera tigris altaica), 1 of 4 fishing cats (Prionailurus viverrinus), 3 of 6 pumas (Puma concolor), 2 of 2 Texas pumas (Puma concolor stanleyana), and 5 (35.7%) of 14 snow leopards (Uncia uncia). Antibodies were found in 10 of 34 feral domestic cats (Felis domesticus) trapped in 3 zoos. Toxoplasma gondii oocysts were not found in any of the 78 fecal samples from wild and domestic cats. Among the macropods, antibodies were detected in 1 of 3 Dama wallabies (Macropus eugenii), 1 of 1 western grey kangaroo (Macropus fuliginosus), 1 of 2 wallaroos (Macropus robustus), 6 of 8 Bennett's wallabies (Macropus rufogriseus), 21 (61.8%) of 34 red kangaroos (Macropus rufus), and 1 of 1 dusky pademelon (Thylogale brunii). Among prosimians, antibodies were detected in 1 of 3 blue-eyed black lemurs (Eulemur macaco flavifrons), 1 of 21 ring-tailed lemurs (Lemur catta), 2 of 9 red-ruffed lemurs (Varecia variegata rubra), and 2 of 4 black- and white-ruffed lemurs (Varecia variegata variegata).

The relative role of captive breeding and of zoo-bred animals in North American conservation translocations.

With the loss of biodiversity accelerating, conservation translocations such as reintroductions are becoming an increasingly common conservation tool. Conservation translocations must source individuals for release from either wild or captive-bred populations. We asked what proportion of North American conservation translocations rely on captive breeding, and to what extent zoos and aquaria (hereafter zoos) fulfill captive breeding needs. Our comprehensive literature review indicates that North American conservation translocations published before 2014 involved captive breeding for 162 (58%) of the 279 animal species translocated. Fifty-four zoos contributed animals for release; the fourty species of animals bred for release by zoos represents only 14% of all animal species for which conservation translocations were published, and only 25% of all animal species that were bred for releases occurring in North America. Zoo contributions varied by taxon, ranging from zoo-bred animals released in 42% of amphibian conservation translocations to zero contributions for marine invertebrates. Proportional involvement of zoos in captive breeding programs for release has increased over time as has the proportion of translocation-focused scientific papers co-authored by zoo professionals. While zoos also contribute to conservation translocations through education, funding, and professional expertise, increasing the contribution of animals for release in responsible conservation translocation programs presents a future conservation need and opportunity. We especially encourage increased dialogue and planning between the zoo community, academic institutions, and governments to optimize the direct contribution zoos can make to wildlife conservation through conservation translocations.

[Cognitive enrichment in zoo and farm animals--implications for animal behaviour and welfare].

PubMed

Meyer, Susann; Puppe, Birger; Langbein, Jan

2010-01-01

Animals in the wild are facing a wide variety of challenges and ever-changing environmental stimuli. For successful coping, animals use both innate behavioural programs and their cognitive skills. In contrast, zoo- and farm animals have to cope with restricted husbandry conditions, which offer only few opportunities to adequately satisfy their various needs. Consequences could be sensory and cognitive underchallenge that can cause boredom and frustration as well as behavioural disturbances. Initially intended for improvement of management and husbandry, different forms of operant behavioural training have been applied firstly in zoo- and later also in farm animals. It has been suggested that successful coping with appropriate cognitive challenges is a source of positive emotions and may lead to improved welfare. Under the term cognitive enrichment, new approaches have been developed to integrate cognitive challenges into the housing of zoo- and farm animals. The present article reviews actual research in the field. Previous results indicate that, beyond improvement of management and handling routines, such approaches can positively affect animal behaviour and welfare. The combination of explorative and appetitive behaviour with successful learning improves environmental predictability and controllability for the animals, activates reward-related brain systems and can directly affect emotional processes of appraisal. For practical implementation in farm animal husbandry, it sounds promising to link individual access to e.g. automated feeders or milking systems with previously conditioned stimuli and/or discriminatory learning tasks. First experimental approaches in pigs, dwarf goats and cattle are available and will be discussed in the present article.

A Comparison of Zoo Animal Behavior in the Presence of Familiar and Unfamiliar People.

PubMed

Martin, Rosemary Anne; Melfi, Vicky

2016-01-01

As recorded in domestic nonhuman animals, regular interactions between animals in zoos and keepers and the resulting relationship formed (human-animal relationship [HAR]) are likely to influence the animals' behaviors with associated welfare consequences. HAR formation requires that zoo animals distinguish between familiar and unfamiliar people. This ability was tested by comparing zoo animal behavioral responses to familiar (routine) keepers and unfamiliar keepers (participants in the "Keeper for the Day" program). Study subjects included 1 African elephant (Loxodonta Africana), 3 Rothschild's giraffes (Giraffa camelopardalis rothschildi), 2 Brazilian tapir (Tapirus terrestris), and 2 slender-tailed meerkats (Suricata suricatta). Different behavior was evident and observed as decreased avoidance behavior toward familiar keepers (t7 = 6.00, p <  .001). This finding suggests the zoo animals have a lower level of fear toward familiar keepers. Keeper familiarity did not significantly affect any other behavioral measure. This finding suggests that in the current study, unfamiliar keeper presence did not appear to have detrimental effects. Furthermore, unfamiliar keeper-animal interactions could provide an increased number of positive human-animal interactions and potentially enhance animal welfare.

Programmatic approaches to assessing and improving animal welfare in zoos and aquariums.

There continues to be intense public, professional, and scientific focus on the welfare of animals in zoos and aquariums, but implementing welfare assessment tools consistently throughout this community remains challenging. Indirect measures can be used to assess "welfare potential"-the potential that animals will experience good welfare based on the care that they are provided with. Zoos and aquariums focus on welfare potential with their continued commitment to develop animal care guidelines (e.g. Animal Care Manuals) that can play a role within institutional accreditation or certification. The Association of Zoos and Aquariums Animal Welfare Committee has been pursuing approaches to maximize welfare potential by developing the concept of an integrated welfare approach or framework-an attempt to identify recommended animal care programs (e.g. enrichment, nutrition, veterinary care, research, and animal training programs) and their programmatic components. Objectively assessing the influence that animal care recommendations have on the welfare of individual animals is important to determine the efficacy of programmatic approaches. The future of welfare assessment within zoos and aquariums will include population-level evaluations-tracking emerging trends in health and behavior that come from both formal and informal institutional animal reports. Sharing this information, and performing meta-analyses of the data using epidemiological approaches, will become easier with advances in technology and database management software. Identifying welfare "red/green flags" throughout captive populations will provide direction for more focused assessments that will ultimately inform the design of more effective animal care programs.

Animal welfare should be prioritized not only for the animal's life sustainability but also for supporting the sustainability of living organism's life on the earth. However, Indonesian people have not understood it yet, thereby still treating animals arbitrarily and not appreciating either domesticated or wild animals. This research aimed to analyze the zoo agent's action in applying the five freedoms principle for animal welfare in Taman Satwa Taru Jurug (thereafter called TSTJ) or Surakarta Zoo and Gembira Loka Zoo (GLZ) of Yogyakarta Indonesia using Giddens structuration theory. The informants in this comparative study with explorative were organizers, visitors, and stakeholders of zoos selected using purposive sampling technique. The informants consisted of 19 persons: 8 from TSTJ (Code T) and 10 from GLZ (Code G) and representatives from Natural Resource Conservation Center of Central Java (Code B). Data were collected through observation, in-depth interview, and Focus Group Discussion and Documentation. Data were analyzed using an interactive model of analysis consisting of three components: Data reduction, data display, and conclusion drawing. Data validation was carried out using method and data source triangulations. Food, nutrition, and nutrition level have been given consistent with the animals' habit and natural behavior. Animal keepers always maintain their self-cleanliness. GLZ has provided cages according to the technical instruction of constructing ideal cages, but the cages in TSTJ are worrying as they are not consistent with standard, rusty, and damaged, and animals have no partner. Some animals in GLZ are often sick, whereas some animals in TSTJ are dead due to poor maintenance. The iron pillars of cages restrict animal behavior in TSTJ so that they have not had freedom to behave normally yet, whereas, in GLZ, they can move freely in original habitat. The animals in the two zoos have not been free from disruption, stress, and pressure due to the

One petting Al-Zawraa zoological society of Baghdad was investigated for E. coli O157:H7 over a 16-month period that spanned two summer and two autumn seasons. Variation in the occurrence of E. coli O157:H7-positive petting zoo animals was observed, with animals being culture positive only in the summer months but not in the spring, autumn, or winter. E. coli O157:H7 isolates were distinguished by agglutination with E. coli O157:H7 latex reagent (Oxoid), identified among the isolates, which showed that multiple E. coli strains were isolated from one petting zoo animal, in which a single animal simultaneously shed multiple E. coli strains; E. coli O157:H7 was isolated only by selective enrichment culture of 2 g of petting zoo animal feces. In contrast, strains other than O157:H7 were cultured from feces of petting zoo animals without enrichment. PMID:24489514

A clear need for evidence-based animal management in zoos and aquariums has been expressed by industry leaders. Here, we show how individual animal welfare monitoring can be combined with measurement of environmental conditions to inform science-based animal management decisions. Over the last several years, Disney's Animal Kingdom® has been undergoing significant construction and exhibit renovation, warranting institution-wide animal welfare monitoring. Animal care and science staff developed a model that tracked animal keepers' daily assessments of an animal's physical health, behavior, and responses to husbandry activity; these data were matched to different external stimuli and environmental conditions, including sound levels. A case study of a female giant anteater and her environment is presented to illustrate how this process worked. Associated with this case, several sound-reducing barriers were tested for efficacy in mitigating sound. Integrating daily animal welfare assessment with environmental monitoring can lead to a better understanding of animals and their sensory environment and positively impact animal welfare. © 2017 Wiley Periodicals, Inc.

Because many people visit zoos, prevention of zoonoses is important from the standpoint of public health. This study examined the prevalence of Chlamydia among zoo animals in Japan by PCR and characterized these bacteria by performing phylogenetic analyses of the sequences of the variable domain (VD) 2 and VD4 regions of the ompA gene, which encodes the Chlamydia major outer membrane protein. Fecal samples were collected from 1150 zoo animals in five zoos and examined for Chlamydia DNA. Chlamydia psittaci DNA was found in 3.9% of mammals, 7.2% of birds and 8.1% of reptiles. The prevalence of Chlamydia pneumoniae DNA was significantly higher in reptiles (5.8%) than in mammals (0.3%) and birds (0.3%). Phylogenetic analysis of the ompA VD2 region from 18 samples showed that nine were in three different clusters containing C. psittaci strains, six were in a cluster containing C. pneumoniae strains and three each formed a distinct branch. Furthermore, phylogenetic analysis of the ompA VD4 region showed that C. pneumoniae DNAs from reptiles were close to those from human patients. The C. pneumoniae DNAs from the European glass lizard, Emerald tree boa, and Panther chameleon were classified in clusters that were distinct from other strains, suggesting that these reptiles had each been infected with a specific C. pneumoniae genotype. This study showed that diverse Chlamydia strains have been prevalent among a variety of zoo animals. © 2015 The Societies and Wiley Publishing Asia Pty Ltd.

The informants consisted of 19 persons: 8 from TSTJ (Code T) and 10 from GLZ (Code G) and representatives from Natural Resource Conservation Center of Central Java (Code B). Data were collected through observation, in-depth interview, and Focus Group Discussion and Documentation. Data were analyzed using an interactive model of analysis consisting of three components: Data reduction, data display, and conclusion drawing. Data validation was carried out using method and data source triangulations. Results: Food, nutrition, and nutrition level have been given consistent with the animals’ habit and natural behavior. Animal keepers always maintain their self-cleanliness. GLZ has provided cages according to the technical instruction of constructing ideal cages, but the cages in TSTJ are worrying as they are not consistent with standard, rusty, and damaged, and animals have no partner. Some animals in GLZ are often sick, whereas some animals in TSTJ are dead due to poor maintenance. The iron pillars of cages restrict animal behavior in TSTJ so that they have not had freedom to behave normally yet, whereas, in GLZ, they can move freely in original habitat. The animals in the two zoos have not

Antimicrobial resistance of Staphylococcus aureus is a major problem in human and veterinary medicine. The aim of this study was to characterise S. aureus isolates from wild and zoo animals mainly associated with bacterial infections. In total, 23 S. aureus isolates, including nine from wild animals and 14 from zoo animals, were obtained during routine diagnostics. All isolates were subjected to multilocus sequence typing (MLST), spa typing, macrorestriction analysis with subsequent SmaI pulsed-field gelelectrophoresis (PFGE), antimicrobial susceptibility testing and S. aureus-specific DNA-microarray analysis. Resistant isolates were also tested for their respective resistance genes by PCR. Isolates from zoo animals and wildlife showed a high diversity of MLST types, spa types and PFGE patterns. Nineteen different spa types were identified, including three novel types and 16 main macrorestriction patterns. Only few isolates were resistant to members of four classes of antimicrobial agents and harboured the respective resistance genes (β-lactams [blaZ, mecA, mecC], tetracyclines [tet(K), tet(L)] and chloramphenicol [cat pC221 ]) or mutations (fluoroquinolones). The DNA microarray analysis identified one isolate from a zoo animal harbouring the toxic shock syndrome toxin gene tst1. Moreover, several enterotoxin genes were detected in five S. aureus isolates. All isolates were negative for Panton-Valentine leukocidin (PVL) genes, but the animal-associated leukocidin genes lukM/lukF-P83 were found in three isolates from two animals.

The impact of zoo live animal presentations on students' propensity to engage in conservation behaviors

NASA Astrophysics Data System (ADS)

Kirchgessner, Mandy L.

Zoos frequently deploy outreach programs, often called "Zoomobiles," to schools; these programs incorporate zoo resources, such as natural artifacts and live animals, in order to teach standardized content and in hopes of inspiring students to protect the environment. Educational research at zoos is relatively rare, and research on their outreach programs is non-existent. This leaves zoos vulnerable to criticisms as they have little to no evidence that their strategies support their missions, which target conservation outcomes. This study seeks to shed light on this gap by analyzing the impact that live animals have on offsite program participants' interests in animals and subsequent conservation outcomes. The theoretical lens is derived from the field of Conservation Psychology, which believes personal connections with nature serve as the motivational component to engagement with conservation efforts. Using pre, post, and delayed surveys combined with Zoomobile presentation observations, I analyzed the roles of sensory experiences in students' (N=197) development of animal interest and conservation behaviors. Results suggest that touching even one animal during presentations has a significant impact on conservation intents and sustainment of those intents. Although results on interest outcomes are conflicting, this study points to ways this kind of research can make significant contributions to zoo learning outcomes. Other significant variables, such as emotional predispositions and animal-related excitement, are discussed in light of future research directions.

Canine distemper virus (CDV), a morbillivirus that causes one of the most contagious and lethal viral diseases known in canids, has an expanding host range, including wild animals. Since December 2009, several dead or dying wild raccoon dogs (Nyctereutes procyonoides) were found in and around one safari-style zoo in Japan, and CDV was isolated from four of these animals. In the subsequent months (January to February 2010), 12 tigers (Panthera tigris) in the zoo developed respiratory and gastrointestinal diseases, and CDV RNA was detected in fecal samples of the examined tigers. In March 2010, one of the tigers developed a neurological disorder and died; CDV was isolated from the lung of this animal. Sequence analysis of the complete hemagglutinin (H) gene and the signal peptide region of the fusion (F) gene showed high homology among these isolates (99.8-100%), indicating that CDV might have been transmitted from raccoon dog to tiger. In addition, these isolates belonged to genotype Asia-1 and had lower homology (<90%) to the vaccine strain (Onderstepoort). Seropositivity of lions (Panthera leo) in the zoo and wild bears (Ursus thibetanus) captured around this area supported the theory that a CDV epidemic had occurred in many mammal species in and around the zoo. These results indicate a risk of CDV transmission among many animal species, including large felids and endangered species.

An hourly variation in zoo visitor interest: measurement and significance for animal welfare research.

PubMed

Davey, Gareth

2006-01-01

A methodological difficulty facing welfare research on nonhuman animals in the zoo is the large number of uncontrolled variables due to variation within and between study sites. Zoo visitors act as uncontrolled variables, with number, density, size, and behavior constantly changing. This is worrisome because previous research linked visitor variables to animal behavioral changes indicative of stress. There are implications for research design: Studies not accounting for visitors' effect on animal welfare risk confounding (visitor) variables distorting their findings. Zoos need methods to measure and minimize effects of visitor behavior and to ensure that there are no hidden variables in research models. This article identifies a previously unreported variable--hourly variation (decrease) in visitor interest--that may impinge on animal welfare and validates a methodology for measuring it. That visitor interest wanes across the course of the day has important implications for animal welfare management; visitor effects on animal welfare are likely to occur, or intensify, during the morning or in earlier visits when visitor interest is greatest. This article discusses this issue and possible solutions to reduce visitor effects on animal well-being.

A comparative approach to the study of Keeper-Animal Relationships in the zoo.

PubMed

Carlstead, Kathy

2009-11-01

Research on intensively farmed animals over the past 25 years has shown that human-animal interactions, by affecting the animal's fear of humans, can markedly limit the productivity and welfare of farm animals. This article begins to explore some of the factors that need to be considered to investigate Keeper-Animal Relationships (KARs) in the zoo. In the mid-1990s, a large body of multi-institutional data on zookeepers and animals was collected from 46 Zoos. Using standardized questionnaires, 82 keepers rated how they behaved towards animals, their husbandry routine, how the animal responds to them and to other people, and provided information about themselves. These data include 219 individuals of four endangered species: black rhinoceros, cheetah, maned wolf, and great hornbill. At each zoo, keepers were also videotaped calling to their animals in order to directly observe animal responses to keeper behaviors. Principle Components Analysis reduced eight animal variables to three components and ten keeper variables to five components. Scores for animals and for keepers were calculated on these components and compared, according to five predictions based on models of human-animal interactions in the literature. Animal responses to keepers varied along three dimensions: Affinity to Keeper, Fear of People, and Sociable/Curious. Animal scores of Fear of People were significantly and positively correlated with independent measures of poor welfare from two later studies: fecal corticoid concentrations for 12 black rhinos and "tense-fearful" scores for 12 cheetahs. (1) Significant species differences were found for Affinity to Keeper and Fear of People, and the interaction of these two dimensions of animal response to keepers appears to be species-specific. (2) The quality of KAR is influenced by whether the zookeeper goes in the enclosure with the animal or not, the frequency and time of feeding, and keeper visibility to the animal. Among keepers who go in with their

The Animal Welfare Act and the zoo: A positive approach

Interpretations of the Animal Welfare Act and other regulations governing use of research animals in the United States are changing. Recent amendments to the Act have resulted in the inclusion of more species under the umbrella of regulation. The role of the zoo and wildlife veterinarian should be that of leading his or her institution into a positive endorsement of these regulations and their application. Recent additions to the Code of Federal Regulations spell out the roles of the veterinarian and the Animal Care and Use Committee at an institution.

Behavioral ecology of captive species: using behavioral adaptations to assess and enhance welfare of nonhuman zoo animals.

PubMed

Koene, Paul

2013-01-01

This project aimed to estimate a species' adaptations in nature and in captivity, assess welfare, suggest environmental changes, and find species characteristics that underlie welfare problems in nonhuman animals in the zoo. First, the current status of zoo animal welfare assessment was reviewed, and the behavioral ecology approach was outlined. In this approach, databases of species characteristics were developed using (a) literature of natural behavior and (b) captive behavior. Species characteristics were grouped in 8 functional behavioral ecological fitness-related categories: space, time, metabolic, safety, reproductive, comfort, social, and information adaptations. Assessments of the strength of behavioral adaptations in relation to environmental demands were made based on the results available from the literature. The databases with literature at the species level were coupled with databases of (c) behavioral observations and (d) welfare assessments under captive conditions. Observation and welfare assessment methods were adapted from the animal on the farm realm and applied to zoo species. It was expected that the comparison of the repertoire of behaviors in natural and captive environments would highlight welfare problems, provide solutions to welfare problems by environmental changes, and identify species characteristics underlying zoo animal welfare problems.

This study was conducted to evaluate the prevalence of antibodies against Borrelia bugdorferi (Bb) s.l. and tick-borne encephalitis virus (TBEV) in zoo animals in the Czech Republic. We collected 133 serum samples from 69 animal species from 5 zoos located in different parts of the country. The samples were obtained from even-toed ungulates (n=78; 42 species), odd-toed ungulates (n=32; 11 species), carnivores (n=13; 9 species), primates (n=2, 2 species), birds (n=3; 2 species), and reptiles (n=5; 3 species). A high antibody prevalence (60%) was observed for Bb s.l. On the other hand, only two animals had TBEV-specific antibodies: a markhor (Capra falconeri) and a reindeer (Rangifer tarandus), both from the same zoo, located in an area endemic for TBEV. Both of these animals were also positive for Bb s.l. antibodies. Our results indicate that a high number of animal species in the Czech zoos were exposed to Bb s.l. and that TBEV infection occurred at least in one of the investigated zoos. Considering the pathogenic potential of these two tick-borne pathogens, clinical and serological monitoring should be continued, and therapeutic and preventive measures should be taken when necessary.

Arthropods of medicoveterinary importance in zoos.

Adler, Peter H; Tuten, Holly C; Nelder, Mark P

2011-01-01

Zoos present a unique assemblage of arthropods, captive vertebrates, free-roaming wildlife, humans, and plants, each with its own biota of symbiotic organisms. Arthropods of medicoveterinary importance are well represented in zoos, and an ample literature documents their influence in these animal-rich environments. Mosquitoes are of greatest significance because of the animal and human pathogens they transmit, followed by ectoparasites, many of which are exotic and present health risks to captive and native animals. Biting flies, cockroaches, filth flies, and triatomid bugs represent additional concerns. Integrated management programs for arthropods in zoos are commonplace. Zoos can play a role in biosurveillance, serving as an advanced guard for detecting exotic arthropods and vector-borne diseases. We provide the first review of arthropods of medicoveterinary importance in zoos. A case is made for the value of collaborations between entomologists and zoo personnel as a means of enhancing research and public education while safeguarding the health of captive animals and the public.

Chagas, Carolina Romeiro Fernandes; Gonzalez, Irys Hany Lima; Favoretto, Samantha Mesquita; Ramos, Patrícia Locosque

Rattus norvegicus (Mammalia: Rodentia) is a widespread and synanthropic rodent, broadly used in medical experiments. It can also be used for feeding captive animals in zoos. Parasitological surveys are important to guarantee the health of both the animals and the staff responsible for their management. The aim of this study was to identify intestinal parasites of Rattus norvegicus offered as food to captive animals from São Paulo Zoo, and demonstrate the importance of sanitary hurdling, disease control and biosecurity. The identified protozoan parasites were Eimeria sp., Entamoeba sp., Spironucleus sp., Giardia sp., Tritrichomonas sp., Chilomastix sp., unidentified cysts and non-sporulated coccidians oocysts (Isospora/Eimeria). The following helminths were found: Syphacia muris, Rodentolepis nana and Aspiculuris tetraptera.

Survey of U.S. zoo and aquarium animal care staff attitudes regarding humane euthanasia for population management.

Powell, David M; Ardaiolo, Matthew

2016-05-01

The humane euthanasia of animals for population management, or culling, has been suggested as one possible tool for managing animal populations for sustainability, and recent, highly publicized euthanasia of zoo animals in Copenhagen has stimulated global conversation about population management in zoos. We conducted a nationwide survey of U.S. zoo and aquarium personnel, including keepers, managers, and leaders of AZA animal programs, to assess their overall attitudes regarding population management euthanasia. The surveyed populations were generally very aware of the concept of population management euthanasia. Managers and animal program leaders were more supportive of euthanasia than keepers. We found that regardless of role, men were more supportive of euthanasia than women. Those personnel who were aware of instances of population management euthanasia at their institutions before were more supportive of it than those who were not. Support for culling varied with the kind of animal being considered for it, with three general taxon acceptability groupings emerging. Education, tenure in the profession, taxonomic expertise, and whether or not the responder took the survey before or after the Copenhagen events were not strong predictors of attitudes. Overall, the surveyed populations were approximately evenly split in terms of being in favor of euthanasia, not supporting euthanasia, or being unsure. Most responders indicated that they would be more likely to accept culling if more information was provided on its rationale. These results will form the basis for further discussions on the role of humane euthanasia for population management.

Toxoplasma gondii is a zoonotic protozoan parasite that infects a wide range of warm-blooded animals throughout the world. In the present study, antibodies to T. gondii were determined using a commercial indirect hemagglutination (IHA) test in wild animals in a zoo. Three of 11 giraffes (Giraffa camelopardalis) (27%), 1 of 5 wolves (Canis lupus laniger) (20%), 1 of 6 hippopotamuses (Hippopotamus amphibious) (17%), and 2 of 9 tundra swans (Cygnus columbianus) (22%) were found to be positive. No antibodies were detected in leopards (Panthera pardus), wild geese (Anser cygnoides), and Eastern grey kangaroos (Macropus giganteus). Domestic species from 13 counties of Jiangxi Province, China were also investigated by an indirect hemagglutination (IHA) test. Thirty-five of 340 goats (10%), 94 of 560 water buffaloes (17%), and 4 of 35 cattle (11%) were found to be seropositive.

This article concerns animal experimentation and official Mexican norm Nom 0062-Zoo-1999 entitled Technical specifications for the production, care and use of laboratory animals. The history of animal experimentation is briefly resumed. During the nineteenth century, doubts arose as to the right to expose animals to experimental procedures that frequently cause pain and suffering. The first law which protected animals against cruelty was passed in Great Britain in 1876; subsequently, other nations approved similar legislation. During the second part of the twentieth century, opposition to animal experimentation grew. Other groups, mainly scientists and pharmaceutical concerns, defended the right to use animals in research. New knowledge concerning the neurophysiology, cognitive capacity, and the animal faculty to experience pain is briefly mentioned. Guidelines on care and use of animals used in research published in several countries are listed. Finally, the recently published Mexican legislation (Norm) referring to production, care and use of laboratory animals is discussed and its benefits are stressed.

Malassezia furfur is traditionally associated to human skin, although more recent studies have been revealing its presence in a variety of animals. The aim of this study was to analyze phenotypically and genetically the diversity among strains isolated from animals of this species. We have examined 21 strains of M. furfur from domestic and wild animals held in captivity. On the one hand, their phenotypic characteristics were studied, by assessing its growth at different incubation temperatures, their catalase and β-glucosidase activities and the Tween diffusion test on Sabouraud glucose agar (SGA), and on yeast nitrogen base agar (YNBA), a synthetic medium without lipids. On the other hand, the large subunit (LSU) and the internal transcribed spacer (ITS) of ribosomal RNA and the β-tubulin gene were sequenced. Different sequence types were identified for each target gene, and fourteen genotypes were revealed. While several genotypes were obtained from the strains from domestic animals, the strains from zoo animals appeared to be genetically more stable. With ITS and β-tubulin gene, M. furfur strains grouped in two clades. One clade included the strains from domestic animals and the other clade included the strains from zoo animals. The phenotypic tests also revealed a remarkable diversity within this species, which appeared to be more significant among strains from domestic animals. Moreover, the Tween diffusion test using YNBA was more useful to observe differences among strains, which could not be perceived using SGA. © The Author(s) 2017.

Maple, Terry L; Segura, Valerie D

2015-05-01

Zoos, aquariums, and other captive animal facilities offer promising opportunities to advance the science and practice of behavior analysis. Zoos and aquariums are necessarily concerned with the health and well-being of their charges and are held to a high standard by their supporters (visitors, members, and donors), organized critics, and the media. Zoos and aquariums offer unique venues for teaching and research and a locus for expanding the footprint of behavior analysis. In North America, Europe, and the UK, formal agreements between zoos, aquariums, and university graduate departments have been operating successfully for decades. To expand on this model, it will be necessary to help zoo and aquarium managers throughout the world to recognize the value of behavior analysis in the delivery of essential animal health and welfare services. Academic institutions, administrators, and invested faculty should consider the utility of training students to meet the growing needs of applied behavior analysis in zoos and aquariums and other animal facilities such as primate research centers, sanctuaries, and rescue centers.

Knowledge, Interest, and Value of Youth Zoo Visitors

NASA Astrophysics Data System (ADS)

Burris, Alexandra M.

In the face of massive global extinction, the mission of zoos for conservation education has increasing importance. Zoos are in a unique position to affect the development of youth in ways that are consistent with cultivating pro-environmental behaviors. The purpose of this study was to examine three intrinsic traits of youth important to the goals of conservation education: knowledge about animals, interest in animals, and value for animals. In particular, I explored the relationship between these three traits and the utterances and behaviors of youth zoo visitors during their visit. Using an embedded correlational data transformation mixed methods design, this study examined the experiences of 37 youth attending the zoo. Data collection sources included a drawing activity meant to assess the knowledge of youth about animals, Likert-type questionnaires meant to assess the youth's interest and value, and a semi-structured interview meant to ascertain critical moments from the youth's visit. The results of these instruments were paired with extensive video data of the youth's entire zoo visit. Results of the study indicated that youth organize their knowledge about animals around ecological and morphological concepts and that this forms the basis for their value of animals. The knowledge, interest, and value of youth zoo visitors did seem to correlate with some utterances and behaviors in the zoo, but learning talk was rare. Results also indicated that certain critical moments during the youth's visit were social in nature and centered on the behaviors of animals. These moments may be the most promising for influencing the development of knowledge, interest, and value. The discussion and implications sections of the study focus on the practical use of the findings for zoo education. The study points to the importance of studying intrinsic traits of youth as well as the important influences of the social and physical context on the development of these traits during

Faecal prevalence of gastrointestinal bacterial pathogens, including Campylobacter, Escherichia coli O157:H7, Salmonella, Shigella, Yersinia, as well as Arcobacter, were examined in 317 faecal specimens from 44 animal species in Belfast Zoological Gardens, during July-September 2006. Thermophilic campylobacters including Campylobacter jejuni, Campylobacter coli and Campylobacter lari, were the most frequently isolated pathogens, where members of this genus were isolated from 11 animal species (11 of 44; 25%). Yersinia spp. were isolated from seven animal species (seven of 44; 15.9%) and included, Yersinia enterocolitica (five of seven isolates; 71.4%) and one isolate each of Yersinia frederiksenii and Yersinia kristensenii. Only one isolate of Salmonella was obtained throughout the entire study, which was an isolate of Salmonella dublin (O 1,9,12: H g, p), originating from tiger faeces after enrichment. None of the animal species found in public contact areas of the zoo were positive for any gastrointestinal bacterial pathogens. Also, water from the lake in the centre of the grounds, was examined for the same bacterial pathogens and was found to contain C. jejuni. This study is the first report on the isolation of a number of important bacterial pathogens from a variety of novel host species, C. jejuni from the red kangaroo (Macropus rufus), C. lari from a maned wolf (Chrysocyon brachyurus), Y. kristensenii from a vicugna (Vicugna vicugna) and Y. enterocolitica from a maned wolf and red panda (Ailurus fulgens). In conclusion, this study demonstrated that the faeces of animals in public contact areas of the zoo were not positive for the bacterial gastrointestinal pathogens examined. This is reassuring for the public health of visitors, particularly children, who enjoy this educational and recreational resource.

An investigation into the determining factors of zoo visitor attendances in UK zoos.

Whitworth, Andrew William

2012-01-01

The debate as to which animals are most beneficial to keep in zoos in terms of financial and conservative value is readily disputed; however, demographic factors have also been shown to relate to visitor numbers on an international level. The main aims of this research were: (1) To observe the distribution and location of zoos across the UK, (2) to develop a way of calculating zoo popularity in terms of the species kept within a collection and (3) to investigate the factors related to visitor numbers regarding admission costs, popularity of the collection in terms of the species kept and local demographic factors. Zoo visitor numbers were positively correlated with generated popularity ratings for zoos based on the species kept within a collection and admission prices (Pearson correlation: n = 34, r = 0.268, P = 0.126 and n = 34, r = -0.430, P = 0.011). Animal collections are aggregated around large cities and tourist regions, particularly coastal areas. No relationship between demographic variables and visitor numbers was found (Pearson correlation: n = 34, r = 0.268, P = 0.126), which suggests that the popularity of a zoo's collection relative to the types and numbers of species kept is more indicative of a collection's visitor numbers than its surrounding demographic figures. Zoos should incorporate generating high popularity scores as part of their collection planning strategies, to ensure that they thrive in the future, not only as tourist attractions but also as major conservation organizations.

The main aims of this research were: (1) To observe the distribution and location of zoos across the UK, (2) to develop a way of calculating zoo popularity in terms of the species kept within a collection and (3) to investigate the factors related to visitor numbers regarding admission costs, popularity of the collection in terms of the species kept and local demographic factors. Zoo visitor numbers were positively correlated with generated popularity ratings for zoos based on the species kept within a collection and admission prices (Pearson correlation: n = 34, r = 0.268, P = 0.126 and n = 34, r = −0.430, P = 0.011). Animal collections are aggregated around large cities and tourist regions, particularly coastal areas. No relationship between demographic variables and visitor numbers was found (Pearson correlation: n = 34, r = 0.268, P = 0.126), which suggests that the popularity of a zoo's collection relative to the types and numbers of species kept is more indicative of a collection's visitor numbers than its surrounding demographic figures. Zoos should incorporate generating high popularity scores as part of their collection planning strategies, to ensure that they thrive in the future, not only as tourist attractions but also as major conservation organizations.

Interpretive signs designed to trigger naturalist intelligence at two American zoos

NASA Astrophysics Data System (ADS)

Bryant, Martha

An investigation of interpretive graphics was conducted in 2005 at two mid-sized AZA-accredited zoos, Lowry Park Zoo, Tampa, Florida and Knoxville Zoo, Knoxville, Tennessee. The Lowry Park Zoo study investigated signs at a red-tailed hawk and sandhill crane exhibit. Combination signs and wordless signs were more effective helping visitors see animals, increasing holding time, and number of engagements than treatments of no signs, or signs with words only. A second study, at Knoxville Zoo, tested combination and wordless signs in a children's zoo, investigating 31 signs at a 3.5-acre exhibit. Comparisons of visitors seeing the animals/using interactive exhibit elements, holding time, and engagement activities, showed wordless signs were more effective than combination signs. Differences in gender ratio, age, group size, and other demographics were not significant. Visit motivation differed between zoos, with visitors from Lowry Park Zoo more often articulating reason for a visit as wanting to see animals. Visitors at Knoxville Zoo most often said they wanted to spend time with family and friends. Differences in potential for naturalist intelligence were probably related to local practices rather than to innate differences in naturalist intelligence. The number of communities in Florida that regulate pet ownership and provide lawn service could account for the lower number of people who have pets and plants. At both institutions, behaviors supported educational theories. The importance of signs as advanced organizers was shown where signs were removed at the bird exhibit at Lowry Park Zoo, with fewer visitors seeing the animals. Social interaction was noted at both zoos, with intra- and inter-group conversations observed. If naturalist intelligence is necessary to see animals, visitors run a continuum. Some are unable to see animals with signs and assistance from other visitors; others see animals with little difficulty. The importance of honing naturalist

A computer-controlled touchscreen apparatus (hereafter referred to as "touchscreen") in the orangutan exhibit at Zoo Atlanta provides enrichment to the animals and allows cognitive research to take place on exhibit. This study investigated the impact of the touchscreen on orangutan behavior and visibility, as well as its impact on zoo visitors. Despite previous research suggesting that providing a single computer system may negatively affect orangutan behavior, there was not a significant increase in aggression, stereotypic, or distress-related behaviors following the activation of the on-exhibit touchscreen. We also investigated the possibility that zoo visitors may be negatively affected by technology because it deviates from naturalism. However, we did not find a change in stay time or overall experience rating when the computer was turned on. This research was the first to assess visitor attitudes toward technology at the zoo, and we found that visitors report highly positive attitudes about technology for both animals and visitors. If subjects visited the exhibit when the computer was turned on, they more strongly agreed that orangutans benefit from interacting with computerized enrichment. This study is the first investigation of an on-exhibit touchscreen in group-housed apes; our findings of no negative effects on the animals or zoo visitors and positive attitudes toward technology suggest a significant value of this practice. © 2011 Wiley Periodicals, Inc.

Human factors analyses have been used to improve efficiency and safety in various work environments. Although generally limited to humans, the universality of these analyses allows for their formal application to a much broader domain. This paper outlines a model for the use of human factors to enhance zoo exhibits and optimize spaces for all user groups; zoo animals, zoo visitors, and zoo staff members. Zoo exhibits are multi-faceted and each user group has a distinct set of requirements that can clash or complement each other. Careful analysis and a reframing of the three groups as interdependent coworkers can enhance safety, efficiency, and experience for all user groups. This paper details a general creation and specific examples of the use of the modified human factors tools of function allocation, operational sequence diagram and needs assessment. These tools allow for adaptability and ease of understanding in the design or renovation of exhibits. © 2014 Wiley Periodicals, Inc.

LESSONS FROM A RETROSPECTIVE ANALYSIS OF A 5-YR PERIOD OF PRESHIPMENT TESTING AT SAN DIEGO ZOO: A RISK-BASED APPROACH TO PRESHIPMENT TESTING MAY BENEFIT ANIMAL WELFARE.

The preshipment examination, with associated transmissible disease testing, has become standard practice in the movement of animals between zoos. An alternative disease risk-based approach, based on a comprehensive surveillance program including necropsy and preventive medicine examination testing and data, has been in practice since 2006 between the San Diego Zoo and San Diego Zoo Safari Park. A retrospective analysis, evaluating comprehensive necropsy data and preshipment testing over a 5-yr study period, was performed to determine the viability of this model for use with sending animals to other institutions. Animals (607 birds, 704 reptiles and amphibians, and 341 mammals) were shipped to 116 Association of Zoos and Aquariums (AZA)-accredited and 29 non-AZA-accredited institutions. The evaluation showed no evidence of the specific transmissible diseases tested for during the preshipment exam being present within the San Diego Zoo collection. We suggest that a risk-based animal and institution-specific approach to transmissible disease preshipment testing is more cost effective and is in the better interest of animal welfare than the current industry standard of dogmatic preshipment testing.

Many public venues such as farms, fairs, and petting zoos encourage animal contact for both educational and entertainment purposes. However, healthy farm animals, including cattle, small ruminants, and poultry, can be reservoirs for enteric zoonotic pathogens, with human infections resulting in nausea, vomiting, diarrhea, and, in some cases, severe complications that can lead to death. As animals shed these organisms in their feces, contamination of themselves and their surroundings is unavoidable. The majority of North Americans reside in urban and suburban settings, and the general public often possess limited knowledge of agricultural practices and minimal contact with farm animals. Furthermore, there is a lack of understanding of zoonotic pathogens, particularly how these pathogens are spread and the human behaviors that may increase the risk of infection. Human risk behaviors include hand-to-mouth contact immediately after physical contact with animals and their environments, a practice that facilitates the ingestion of pathogens. It is often young children who become ill due to their under-developed immune systems and poorer hygienic practices compared with adults, such as more frequent hand-to-mouth behaviors, and infrequent or improper hand washing. These illnesses are often preventable, simply through adequate hygiene and hand washing. Our objective was to use a structured approach to review the main causal organisms responsible for human illnesses acquired in petting zoo and open farm environments, Shiga toxin-producing Escherichia coli, nontyphoidal Salmonella, Campylobacter, and Cryptosporidium. Notable outbreaks involving direct contact with farm animals and farm, fair, or petting zoo environments are discussed and recommendations for how public venues can increase safety and hand hygiene compliance among visitors are proposed. The most effective protective measures against enteric illnesses include education of the public, increasing overall awareness

To determine if the unique host assemblages in zoos influence blood-feeding by mosquitoes (Diptera: Culicidae), a sampling programme was conducted in Greenville and Riverbanks Zoos, South Carolina, U.S.A., from April 2009 to October 2010. A total of 4355 female mosquitoes of 14 species were collected, of which 106 individuals of nine species were blood-fed. The most common taxa were Aedes albopictus (Skuse), Aedes triseriatus (Say), Anopheles punctipennis (Say), Culex erraticus (Dyar & Knab), Culex pipiens complex (L.) and Culex restuans (Theobald). Molecular analyses (cytochrome b) of bloodmeals revealed that mosquitoes fed on captive animals, humans and wildlife, and took mixed bloodmeals. Host species included one amphibian, 16 birds, 10 mammals (including humans) and two reptiles. Minimum dispersal distances after feeding on captive hosts ranged from 15.5 m to 327.0 m. Mosquito-host associations generally conformed to previous accounts, indicating that mosquito behaviour inside zoos reflects that outside zoos. However, novel variation in host use, including new, exotic host records, warrants further investigation. Zoos, thus, can be used as experiment environments in which to study mosquito behaviour, and the findings extrapolated to non-zoo areas, while providing medical and veterinary benefits to zoo animals, employees and patrons. © 2012 The Authors.

Hepatitis E virus and related viruses in wild, domestic and zoo animals: A review.

PubMed

Spahr, C; Knauf-Witzens, T; Vahlenkamp, T; Ulrich, R G; Johne, R

Hepatitis E is a human disease mainly characterized by acute liver illness, which is caused by infection with the hepatitis E virus (HEV). Large hepatitis E outbreaks have been described in developing countries; however, the disease is also increasingly recognized in industrialized countries. Mortality rates up to 25% have been described for pregnant women during outbreaks in developing countries. In addition, chronic disease courses could be observed in immunocompromised transplant patients. Whereas the HEV genotypes 1 and 2 are mainly confined to humans, genotypes 3 and 4 are also found in animals and can be zoonotically transmitted to humans. Domestic pig and wild boar represent the most important reservoirs for these genotypes. A distinct subtype of genotype 3 has been repeatedly detected in rabbits and a few human patients. Recently, HEV genotype 7 has been identified in dromedary camels and in an immunocompromised transplant patient. The reservoir animals get infected with HEV without showing any clinical symptoms. Besides these well-known animal reservoirs, HEV-specific antibodies and/or the genome of HEV or HEV-related viruses have also been detected in many other animal species, including primates, other mammals and birds. In particular, genotypes 3 and 4 infections are documented in many domestic, wildlife and zoo animal species. In most cases, the presence of HEV in these animals can be explained by spillover infections, but a risk of virus transmission through contact with humans cannot be excluded. This review gives a general overview on the transmission pathways of HEV to humans. It particularly focuses on reported serological and molecular evidence of infections in wild, domestic and zoo animals with HEV or HEV-related viruses. The role of these animals for transmission of HEV to humans and other animals is discussed. © 2017 Blackwell Verlag GmbH.

Although petting zoos are common at public events and allow the public to interact with animals, there has been minimal evaluation of practices at petting zoos. Unannounced observation was performed at 36 petting zoos in Ontario, Canada. Observers recorded information, including physical layout, animal species, animal health, types of animal contact permitted, animal sources, hand hygiene facilities, signage, sale of food for human consumption, and hand hygiene compliance. The majority of petting zoos (24 [67%] of 36 petting zoos) were part of temporary events, particularly agricultural fairs (21 [58%] of 36 petting zoos). A variety of animal species were present, including some animals that are considered to be at particularly high risk for disease transmission (neonatal calves and baby chicks). The following items that would come into contact with the mouths of infants and children were carried into the petting zoos: baby bottles (at 17 petting zoos; 50%), pacifiers (at 24 petting zoos; 71%), spill-proofs cups (at 19 petting zoos; 56%), and infant toys (at 22 petting zoos; 65%). Hand hygiene facilities were provided at 34 (94%) of 36 events, and hand hygiene compliance ranged from 0% through 77% (mean compliance [+/-SD], 30.9%+/-22.1%; median compliance, 26.5%). Predictors for increased hand hygiene compliance included the location of a hand hygiene station on an exit route, the presence of hand hygiene reminder signs, and the availability of running water. Numerous deficiencies were encountered. Better education of petting zoo operators and the general public is needed. Provision of hand hygiene stations with running water that are placed near exits is one effective way to encourage compliance.

Animal enclosures are often constructed from wood treated with the pesticide chromated copper arsenate (CCA), which leaches arsenic (As) into adjacent soil during normal weathering. This study evaluated potential pathways of As exposure in 25 species of zoo animals living in CCA-wood enclosures. We analyzed As speciation in complete animal foods, dislodgeable As from CCA-wood, and As levels in enclosure soils, as well as As levels in biomarkers of 9 species of crocodilians (eggs), 4 species of birds (feathers), 1 primate species (hair), and 1 porcupine species (quills). Elevated soil As in samples from 17 enclosures was observed at 1.0-110mg/kg, and enclosures housing threatened and endangered species had As levels higher than USEPA's risk-based Eco-SSL for birds and mammals of 43 and 46mg/kg. Wipe samples of CCA-wood on which primates sit had dislodgeable As residues of 4.6-111μg/100cm(2), typical of unsealed CCA-wood. Inorganic As doses from animal foods were estimated at 0.22-7.8μg/kg bw/d. Some As levels in bird feathers and crocodilian eggs were higher than prior studies on wild species. However, hair from marmosets had 6.37mg/kg As, 30-fold greater than the reference value, possibly due to their inability to methylate inorganic As. Our data suggested that elevated As in soils and dislodgeable As from CCA-wood could be important sources of As exposure for zoo animals. Published by Elsevier B.V.

Animal contact is a potential transmission route for campylobacteriosis, and both domestic household pet and petting zoo exposures have been identified as potential sources of exposure. Research has typically focussed on the prevalence, concentration, and transmission of zoonoses from farm animals to humans, yet there are gaps in our understanding of these factors among animals in contact with the public who don’t live on or visit farms. This study aims to quantify, through a systematic review and meta-analysis, the prevalence and concentration of Campylobacter carriage in household pets and petting zoo animals. Four databases were accessed for the systematic review (PubMed, CAB direct, ProQuest, and Web of Science) for papers published in English from 1992–2012, and studies were included if they examined the animal population of interest, assessed prevalence or concentration with fecal, hair coat, oral, or urine exposure routes (although only articles that examined fecal routes were found), and if the research was based in Canada, USA, Europe, Australia, and New Zealand. Studies were reviewed for qualitative synthesis and meta-analysis by two reviewers, compiled into a database, and relevant studies were used to create a weighted mean prevalence value. There were insufficient data to run a meta-analysis of concentration values, a noted study limitation. The mean prevalence of Campylobacter in petting zoo animals is 6.5% based on 7 studies, and in household pets the mean is 24.7% based on 34 studies. Our estimated concentration values were: 7.65x103cfu/g for petting zoo animals, and 2.9x105cfu/g for household pets. These results indicate that Campylobacter prevalence and concentration are lower in petting zoo animals compared with household pets and that both of these animal sources have a lower prevalence compared with farm animals that do not come into contact with the public. There is a lack of studies on Campylobacter in petting zoos and/or fair animals in

OBJECTIVE: To determine the cause of an outbreak of Escherichia coli 0157:H7 related to animal exposures so that further transmission could be prevented. DESIGN: Description of laboratory investigations and a case control study. SETTING: Agricultural pavilion at an annual fair in Ontario. POPULATION: People with laboratory evidence of E coli 0157:H7 (seven people) and others with diarrhea (155 people) who called the health unit following a media release were interviewed. Animals that were accessed most frequently by the public in the agriculture pavilion were tested for E coli 0157:H7. In the case control study, a case was defined as someone with laboratory confirmed E coli 0157:H7, or someone who developed severe or bloody diarrhea two to eight days after attending the agricultural pavilion at the fair (61 people). A convenience sample of people who attended the agricultural pavilion but did not develop diarrhea was selected as the control group (89 people). INTERVENTIONS: Human and animal E coli 0157:H7 specimens were subtyped. Cases and controls were interviewed using a standardized questionnaire. RESULTS: Subtyping of the seven human isolates of E coli 0157:H7 revealed five that were of an extremely uncommon phage type. Three samples from goats and one from sheep at the petting zoo in the agricultural pavilion were of this same phage type. The case control study also implicated goats (odds ratio [OR] 3.65; 95% CI 1.63 to 8.52) and sheep (OR 2.94; 95% CI 1.33 to 6.57) from the petting zoo. CONCLUSIONS: Results of this investigation suggest strongly that the goats and sheep from the petting zoo were the source of this outbreak of E coli 0157:H7. PMID:18159389

Evaluating children's conservation biology learning at the zoo.

Millions of children visit zoos every year with parents or schools to encounter wildlife firsthand. Public conservation education is a requirement for membership in professional zoo associations. However, in recent years zoos have been criticized for failing to educate the public on conservation issues and related biological concepts, such as animal adaptation to habitats. I used matched pre- and postvisit mixed methods questionnaires to investigate the educational value of zoo visits for children aged 7-15 years. The questionnaires gathered qualitative data from these individuals, including zoo-related thoughts and an annotated drawing of a habitat. A content analysis of these qualitative data produced the quantitative data reported in this article. I evaluated the relative learning outcomes of educator-guided and unguided zoo visits at London Zoo, both in terms of learning about conservation biology (measured by annotated drawings) and changing attitudes toward wildlife conservation (measured using thought-listing data). Forty-one percent of educator-guided visits and 34% of unguided visits resulted in conservation biology-related learning. Negative changes in children's understanding of animals and their habitats were more prevalent in unguided zoo visits. Overall, my results show the potential educational value of visiting zoos for children. However, they also suggest that zoos' standard unguided interpretive materials are insufficient for achieving the best outcomes for visiting children. These results support a theoretical model of conservation biology learning that frames conservation educators as toolmakers who develop conceptual resources to enhance children's understanding of science. © 2014 Society for Conservation Biology.

More than 200 diseases are known to be transmitable from animals to humans. These zoonotic infections (zoonoses) are considered as a major occupational health risk among zoo workers, including veterinarians and animal handlers. In order to prevent possible pathogen transmission, precaution measures for workers, visitors and animals are important, as well as institutional hygiene. Construction of a zoonoses control system at a zoo is presented in this report. There are two main components of this system: 1. routine disease prevention activity, 2. action planning for crisis. Workers, an operating officer, an occupational physician and a veterinarian from the zoo cooperated with infection control professionals from the local community.

Concerns about animal welfare increasingly shape people's views about the acceptability of keeping animals for food production, biomedical research, and in zoos. The field of animal welfare science has developed over the past 50 years as a method of investigating these concerns via research that assesses how living in human-controlled environments influences the behavior, health and affective states of animals. Initially, animal welfare research focused on animals in agricultural settings, but the field has expanded to zoos because good animal welfare is essential to zoos' mission of promoting connections between animals and visitors and raising awareness of conservation issues. A particular challenge for zoos is ensuring good animal welfare for long-lived, highly social species like elephants. Our main goal in conducting an epidemiological study of African (Loxodonta africana) and Asian (Elephas maximus) elephant welfare in 68 accredited North American zoos was to understand the prevalence of welfare indicators in the population and determine the aspects of an elephant's zoo environment, social life and management that are most important to prevent and reduce a variety of welfare problems. In this overview, we provide a summary of the findings of the nine papers in the collection titled: Epidemiological Investigations of North American Zoo Elephant Welfare with a focus on the life history, social, housing, and management factors found to be associated with particular aspects of elephant welfare, including the performance of abnormal behavior, foot and joint problems, recumbence, walking rates, and reproductive health issues. Social and management factors were found to be important for multiple indicators of welfare, while exhibit space was found to be less influential than expected. This body of work results from the largest prospective zoo-based animal welfare study conducted to date and sets in motion the process of using science-based welfare benchmarks to

Reversible contraception that does not alter natural behavior is a critical need for managing zoo populations. In addition to reversible contraception, other fertility techniques perfected in humans may be useful, such as in vitro fertilization (IVF) or oocyte and embryo banking for endangered species like amphibians and Mexican wolves (Canis lupus baileyi). Furthermore, the genetics of human fertility can give a better understanding of fertility in more exotic species. Collaborations were established to apply human fertility techniques to the captive population. Reversible vasectomy might be one solution for reversible contraception that does not alter behavior. Reversible approaches to vasectomy, avoiding secondary epididymal disruption, were attempted in South American bush dogs (Speothos venaticus), chimpanzees (Pan troglodytes), gorillas (Gorilla gorilla), Przewalski's horse (Equus przewalski poliakov), and Sika deer (Cervus nippon) in a variety of zoos around the world. These techniques were first perfected in > 4,000 humans before attempting them in zoo animals. In vitro fertilization with gestational surrogacy was used to attempt to break the vicious cycle of hand rearing of purebred orangutans, and egg and ovary vitrification in humans have led to successful gamete banking for Mexican wolves and disappearing amphibians. The study of the human Y chromosome has even explained a mechanism of extinction related to global climate change. The best results with vasectomy reversal (normal sperm counts, pregnancy, and live offspring) were obtained when the original vasectomy was performed "open-ended," so as to avoid pressure-induced epididymal disruption. The attempt at gestational surrogacy for orangutans failed because of severe male infertility and the lack of success with human ovarian hyperstimulation protocols. Vitrification of oocytes is already being employed for the Amphibian Ark Project and for Mexican wolves. Vasectomy can be a reversible contraception

Unsilencing voices: a study of zoo signs and their language of authority

NASA Astrophysics Data System (ADS)

Fogelberg, Katherine

2014-12-01

Zoo signs are important for informal learning, but their effect on visitor perception of animals has been sparsely studied. Other studies have established the importance of informal learning in American society; this study discusses zoo signs in the context of such learning. Through the lens of Critical Theory framed by informal learning, and by applying critical discourse analysis, I discovered subtle institutional power on zoo signs. This may influence visitors through dominant ideological discursive formations and emergent discourse objects, adding to the paradox of "saving" wild animals while simultaneously oppressing them. Signs covering a variety of species from two different United States-accredited zoos were analyzed. Critical Theory looks to emancipate oppressed human populations; here I apply it zoo animals. As physical emancipation is not practical, I define emancipation in the sociological sense—in this case, freedom from silence. Through this research, perhaps we can find a way to represent animals as living beings who have their own lives and voices, by presenting them honestly, with care and compassion.

Ninety-six fourth and fifth grade children completed curiosity, cognitive, and affective written tests before and after a field trip to the Lowery Park Zoo in Tampa, Florida. The data showed that students were very curious about zoo animals. Dependent T-tests indicated no significant difference between pretest and posttest curiosity levels. The trip did not influence participants' curiosity levels. Multiple regression analysis was used to determine the relationship between the dependent variable, curiosity, and the independent variables, gender, race, prior knowledge, and prior visitation. No significant differences were found. Dependent T-tests indicated no significant difference between pretest and posttest cognitive scores. The field trip to the zoo did not cause an increase in participants' knowledge. However, participants did learn on the trip. After the field trip, participants identified more animals displayed by the zoo than they did before. Also, more animals were identified by species and genus names after the trip than before. These differences were significant (alpha = .05). Multiple regression analysis was used to determine the relationship between the dependent variable, posttest cognitive performance, and the independent variables, curiosity, gender, race, prior knowledge, and prior visitation. A significant difference was found for prior knowledge (alpha = .05). No significant differences were found for the other independent variables. Chi-square tests of significance indicated significant differences

Hepatitis E virus (HEV) is the causative agent of hepatitis E, an emerging infectious disease of humans. HEV infections have also been described in various animal species. Whereas domestic pigs and wild boars are well-known animal reservoirs for HEV, the knowledge on natural HEV infection in zoo animals is scarce so far. Here, we analysed 244 sera from 66 mammal species derived from three zoos in Germany using a commercial double antigen sandwich ELISA. HEV-specific antibodies were detected in 16 animal species, with the highest detection rates in suids (33.3%) and carnivores (27.0%). However, RNA of the human pathogenic HEV genotypes 1-4 was not detected in the serum samples from suids or carnivores. Using a broad spectrum RT-PCR, a ratHEV-related sequence was identified in a sample of a female Syrian brown bear (Ursus arctos syriacus). Subsequent serum samples within a period of five years confirmed a HEV seroconversion in this animal. No symptoms of hepatitis were recorded. In a follow-up investigation at the same location, closely related ratHEV sequences were identified in free-living Norway rats (Rattus norvegicus), whereas feeder rats (Rattus norvegicus forma domestica) were negative for HEV-specific antibodies and RNA. Therefore, a spillover infection of ratHEV from free-living Norway rats is most likely. The results indicate that a wide range of zoo animals can be naturally infected with HEV or HEV-related viruses. Their distinct role as possible reservoir animals for HEV and sources of HEV infection for humans and other animals remains to be investigated. Copyright © 2017 Elsevier B.V. All rights reserved.

Salmonella (S.) enterica and Shiga toxin-producing Escherichia coli (STEC) are foodborne pathogens. Here, we report the prevalence of S. enterica and STEC in feces of 316 zoo animals belonging to 61 species from Chile. S. enterica and STEC strains were detected in 7.5% and 4.4% of animals, respectively. All Salmonella isolates corresponded to the serotype Enteritidis. To the best of our knowledge, this is the first report of S. Enteritidis in the culpeo fox ( Lycalopex culpaeus ), black-capped capuchin ( Sapajus apella ) and Peruvian pelican ( Pelecanus thagus ) and the first STEC report in Thomson's gazelle ( Eudorcas thomsonii ).

In order to address the pervasive trend of underconsumption of fruits and vegetables among children, we examined the hypothesis that children would be more likely to select fruits (apple slices, bananas, and oranges) and vegetables (baby carrots) when paired with animal cartoon image than when available without the character image. Tested in a randomized experiment using counterbalancing, products were arranged on two tables at two separate family fun nights held at a local zoo. Animal character produce parings were manipulated by placing one of two animals (tamarin or iguana) next to two of the four fruit or vegetable selections at each table, and by changing when available without the image. In total, 755 produce selections were made. Significantly more products paired with a character were selected (62.38%) than the same products, not paired (37.62%), χ2 = 46.32, df = 1, p < .001. The odds ratio of the treatment versus control was 1.66 (i.e., 471/284), indicating that children were 66% more likely to select a snack when paired with an animal cartoon. Study findings highlight the positive impact of animal cartoons on children’s fruit and vegetable snack selections, and results suggest the potential for using animal cartoons to encourage fruit and vegetable selection for children.

The global biodiversity crisis requires an engaged citizenry that provides collective support for public policies and recognizes the consequences of personal consumption decisions. Understanding the factors that affect personal engagement in proenvironmental behaviors is essential for the development of actionable conservation solutions. Zoos and aquariums may be some of the only places where many people can explore their relations with wild animals and proenvironmental behaviors. Using a moderated-mediation analysis of a survey of U.S. zoo and aquarium visitors (n = 3588), we explored the relationship between the sense of connection to animals and self-reported engagement in proenvironmental behaviors related to climate change and how this relationship is affected by certainty that climate change is happening, level of concern about climate change, and perceptions of effectiveness in personally addressing climate change. We found a significant, directional relationship between sense of connection to animals and self-reported proenvironmental behaviors. Political inclination within the conservative to liberal spectrum did not affect the relationship. We conclude that a personal sense of connection to animals may provide a foundation for educational and communication strategies to enhance involvement in proenvironmental actions. © 2016 The Authors.

Streptococcus (S.) agalactiae represents a significant pathogen for humans and animals. However, there are only a few elderly reports on S. agalactiae infections in wild and zoo elephants even though this pathogen has been isolated comparatively frequently in these endangered animal species. Consequently, between 2004 and 2015, we collected S. agalactiae isolates from African and Asian elephants (n=23) living in four different zoos in Germany. These isolates were characterised and compared with isolates from other animal species (n=20 isolates) and humans (n=3). We found that the isolates from elephants can be readily identified by classical biochemistry and MALDI-TOF mass spectrometry. Further characterisations for epidemiological issues were achieved using Fourier transform-infrared spectroscopy, capsule typing and molecular fingerprinting (PFGE, RAPD PCR). We could demonstrate that our elephant isolate collection contained at least six different lineages that were representative for their source of origin. Despite generally broad antimicrobial susceptibility of S. agalactiae, many showed tetracycline resistance in vitro. S. agalactiae plays an important role in bacterial infections not only in cattle and humans, but also in elephants. Comparative studies were able to differentiate S. agalactiae isolates from elephants into different infectious clusters based on their epidemiological background. Copyright © 2017 Elsevier B.V.

Zoo Playgrounds: A Source of Enrichment or Stress for a Group of Nearby Cockatoos? A Case Study.

PubMed

Collins, Courtney K; Marples, Nicola M

2015-01-01

There is increasing evidence that in some circumstances, zoo visitors may be aversive stimuli to nonhuman animals housed in zoos. Yet, most previous research has focused on primates with little attention given to numerous other species who are housed in zoos. The focus animal of this project was the cockatoo, a species who has received minimal attention in zoo-based research. Furthermore, although the influence of the zoo setting has become increasingly important in visitor effect studies, this is the 1st study to quantify the effect of activity at a children's playground on zoo animals. There was an investigation on the effect of a zoo playground on the behavior of citron-crested and Moluccan cockatoos (Cacatua sulphurea citrinocristata and Cacatua moluccensis), as well as the effect of children standing in front of the birds' aviaries. The results showed that in some circumstances, the Moluccan cockatoos retreated from visitors, while the citron-crested cockatoos did not retreat from visitors and became more social in the presence of visitors. These findings highlight the importance of careful selection of species and individual animals to be housed near zoo playgrounds.

The endangered red panda (Ailurus fulgens) is held in zoos worldwide. The aim of this study was to examine how red pandas are kept and managed in captivity and to compare it with the management guidelines. Sixty-nine zoos, mainly from Europe but also from North America and Australia/New Zealand, responded to our survey. The results revealed that in general zoos follow the management guidelines for most of the investigated issues. The average enclosure is almost four times larger than the minimum size recommended by the management guidelines, although seven zoos have smaller enclosures. About half the zoos do not follow the guidelines concerning visitor access and number of nest boxes. Other issues that may compromise animal welfare include proximity of neighboring carnivore species and placement of nest boxes. © 2010 Wiley-Liss, Inc.

A cross-sectional study was carried out to determine the prevalence of pathogenic zoonotic agents (flaviviruses, avian influenza viruses (AIVs), Salmonella spp. and Toxoplasma gondii) in feral pigeons and sympatric zoo animals from Córdoba (Southern Spain) between 2013 and 2014. Antibodies against flaviviruses were detected in 7.8% out of 142 (CI95%: 3.7-11.8) pigeons, and 8.2% of 49 (CI95%: 0.9-15.4) of zoo animals tested. Antibodies with specificity against West Nile virus (WNV) and Usutu virus (USUV) were confirmed both in pigeons and in zoo birds. Even though seropositivity to AIVs was not detected in any of the analyzed pigeons, 17.9% of 28 (CI95%: 3.7-32.0) zoo birds tested showed positive results. Salmonella spp. was not isolated in any of 152 fecal samples collected from pigeons, while 6.8% of 44 zoo animals were positive. Antibodies against T. gondii were found in 9.2% of 142 (CI95%: 4.8-13.6) feral pigeons and 26.9% of 108 (CI95%: 19.6-34.1) zoo animals. This is the first study on flaviviruses and T. gondii in feral pigeons and captive zoo species in Spain. Antibodies against WNV and USUV detected in non-migratory pigeons and captive zoo animals indicate local circulation of these emerging pathogens in the study area. T. gondii was widespread in species analyzed. This finding could be of importance for Public Health and Conservation of endangered species present in zoo parks. Pigeons and zoo animals may be included as sentinel species for monitoring zoonotic pathogens in urban areas. Copyright © 2015 Elsevier Ltd. All rights reserved.

Zoos focus on welfare, conservation, education, and research related to animals they keep. Academic institutions emphasize description, experimentation, modeling, and teaching of general and specific animal biology and behavior through work in both laboratory and field. The considerable overlap in concerns and methods has increased interest in collaborative projects, but there is ample room for closer and more extensive interactions. The purpose of this article is to increase awareness of potential research collaborations in three areas: (1) control and analysis of behavior, (2) conservation and propagation of species, and (3) education of students and the general public. In each area, we outline (a) research in zoos, (b) research in academics, and (c) potential collaborative efforts. Zoo Biol 27:470-487, 2008. (c) 2008 Wiley-Liss, Inc.

Outbreaks of human illness have been linked to visiting settings with animal contact throughout developed countries. This study details an observational study of hand hygiene tool availability and recommendations; frequency of risky behaviour; and handwashing attempts by visitors in Kansas (9) and Missouri (4), USA, petting zoos. Handwashing signs and hand hygiene stations were available at the exit of animal-contact areas in 10/13 and 8/13 petting zoos, respectively. Risky behaviours were observed being performed at all petting zoos by at least one visitor. Frequently observed behaviours were as follows: children (10/13 petting zoos) and adults (9/13 petting zoos) touching hands to face within animal-contact areas; animals licking children's and adults' hands (7/13 and 4/13 petting zoos, respectively); and children and adults drinking within animal-contact areas (5/13 petting zoos each). Of 574 visitors observed for hand hygiene when exiting animal-contact areas, 37% (n = 214) of individuals attempted some type of hand hygiene, with male adults, female adults and children attempting at similar rates (32%, 40% and 37%, respectively). Visitors were 4.8× more likely to wash their hands when a staff member was present within or at the exit to the animal-contact area (136/231, 59%) than when no staff member was present (78/343, 23%; P < 0.001, OR = 4.863, 95% CI = 3.380-6.998). Visitors at zoos with a fence as a partial barrier to human-animal contact were 2.3× more likely to wash their hands (188/460, 40.9%) than visitors allowed to enter the animals' yard for contact (26/114, 22.8%; P < 0.001, OR = 2.339, 95% CI = 1.454-3.763). Inconsistencies existed in tool availability, signage and supervision of animal contact. Risk communication was poor, with few petting zoos outlining risks associated with animal contact, or providing recommendations for precautions to be taken to reduce these risks. © 2012 Blackwell Verlag GmbH.

Background: Toxoplasmosis, a worldwide zoonotic disease, is caused by Toxoplasma gondii. The distribution of genetic diversity of T. gondii in wild animals is of great importance to understand the transmission of the parasite in the environment. However, little is known about T. gondii prevalence in wild animals and birds in China. Methods: We conducted the genetic characterization of T. gondii isolated from Zoo Wild Animals and Pet Birds in Fujian Province, Southeastern China. Heart tissues were collected from 45 zoo animals and 140 pet birds. After identified using B1 gene, the genetic diversity of T. gondii isolates were typed at 11 genetic markers, including SAG1, 5’ and 3’-SAG2, alternative SAG2, SAG3, BTUB, GRA6, c22-8, c29-2, L358, PK1, Apico, and CS3. Results: Seven of 45 zoo animals and 3 of 140 pet birds were positive by PCR amplification using T. gondii B1 gene specific primers. Of these positive isolates, 3 isolates from Black-capped (Cebus apella), Peacock (Peafowl) and Budgerigar (Melopsittacus undulatus) were successfully genotyped at 11 genetic loci, and grouped to three distinct genotypes: ToxoDB Genotype #9, #2 and #10, respectively. Conclusion: This is the first genotyping of T. gondii isolated from zoo wild animals and pet birds in Fujian, China. There is a potential risk for the transmission of this parasite through zoo wild animals and pet birds in this region. PMID:26811736

Environmental enrichment in zoos and aquariums is often evaluated at two overlapping levels: published research and day-to-day institutional record keeping. Several authors have discussed ongoing challenges with small sample sizes in between-groups zoological research and have cautioned against the inappropriate use of inferential statistics (Shepherdson, , International Zoo Yearbook, 38, 118-124; Shepherdson, Lewis, Carlstead, Bauman, & Perrin, Applied Animal Behaviour Science, 147, 298-277; Swaisgood, , Applied Animal Behaviour Science, 102, 139-162; Swaisgood & Shepherdson, , Zoo Biology, 24, 499-518). Multi-institutional studies are the typically-prescribed solution, but these are expensive and difficult to carry out. Kuhar ( Zoo Biology, 25, 339-352) provided a reminder that inferential statistics are only necessary when one wishes to draw general conclusions at the population level. Because welfare is assessed at the level of the individual animal, we argue that evaluations of enrichment efficacy are often instances in which inferential statistics may be neither necessary nor appropriate. In recent years, there have been calls for the application of behavior-analytic techniques to zoo animal behavior management, including environmental enrichment (e.g., Bloomsmith, Marr, & Maple, , Applied Animal Behaviour Science, 102, 205-222; Tarou & Bashaw, , Applied Animal Behaviour Science, 102, 189-204). Single-subject (also called single-case, or small-n) designs provide a means of designing evaluations of enrichment efficacy based on an individual's behavior. We discuss how these designs might apply to research and practice goals at zoos and aquariums, contrast them with standard practices in the field, and give examples of how each could be successfully applied in a zoo or aquarium setting. © 2017 Wiley Periodicals, Inc.

Lighting retrofits at the Pittsburgh Zoo and Aviary

DOE Office of Scientific and Technical Information (OSTI.GOV)

Sadowski, E.C.

The Pittsburgh Zoo occupies approximately 52 acres in the City`s Highland Park. Thirty structures serve as animal holding facilities, public display buildings, classrooms, food service facilities, offices, warehouses, a veterinary hospital, and gift shops. The cost of energy for heating, cooling, lighting, pumping, food service, etc. is approximately $280,000 a year. Of this, about 79 percent, or $220,000, is spent for electricity. About 20 percent ($44,000) of that electricity cost is spent directly on lighting. In mid-1992 a series of retrofits to the lighting systems in the Zoo`s buildings was begun. These were completed in mid-1994. These improvements cost $127,690,more » and they are expected to reduce electricity costs by $24,500 a year. The most interesting projects were carried out in the Tropical Forest Building, the Aqua Zoo, and the Niches of the World Building.« less

Lead poisoning was diagnosed post-mortem in 34 simian primates, 11 parrots, and 3 Australian fruit bats at the National Zoological Park. Diagnoses were made by the finding of acid-fast intranuclear inclusion bodies in renal epithelia or hepatocytes and, in most cases, by finding excess lead in samples of liver. The estimated prevalence of lead intoxication among autopsied primates and parrots was 44% and 50% respectively. Leaded paint was found in many animal enclosures at this zoo and it was available to all the lead-poisoned animals in this study. The finding of renal intranuclear inclusion bodies in animals at several zoos,more » scattered reports of lead intoxication of animals dwelling in various zoos, the occurrence of leaded paint in many zoos and the high incidence of lead poisoning at this zoo, indicated that lead poisoning of zoo animals is much more common than was previously thought.« less

Investigation of zoonotic infections among Auckland Zoo staff: 1991-2010.

Investigation was undertaken to assess the occurrence of zoonotic infection among staff at Auckland Zoological Park, New Zealand, in 1991, 2002 and 2010. Serial cross-sectional health surveys in 1991, 2002 and 2010 comprising a health questionnaire, and serological, immunological and microbiological analysis for a range of potential zoonotic infections were performed. Laboratory results for zoo animals were also reviewed for 2004-2010 to assess the occurrence of potential zoonotic infections. Veterinary clinic, animal handler, grounds, maintenance and administrative staff participated in the surveys, with 49, 42 and 46 participants in the 1991, 2002 and 2010 surveys, respectively (29% of total zoo staff in 2010). A small number of staff reported work-related infections, including erysipelas (1), giardiasis (1) and campylobacteriosis (1). The seroprevalence of antibodies to hepatitis A virus and Toxoplasma gondii closely reflected those in the Auckland community. No carriage of hepatitis B virus (HBV) was detected, and most of those with anti-HBV antibodies had been vaccinated. Few staff had serological evidence of past leptospiral infection. Three veterinary clinic staff had raised Chlamydophila psittaci antibodies, all < 1 : 160 indicating past exposure. Two staff (in 1991) had asymptomatic carriage of Giardia lamblia and one person (in 2010) had a dermatophyte infection. After 1991, positive tests indicating exposure to Mycobacterium tuberculosis were < 10%, comparable to the general New Zealand population. Zoo animals had infections with potential zoonotic agents, including G. lamblia, Salmonella spp., Campylobacter spp. and T. gondii, although the occurrence was low. Zoonotic agents pose an occupational risk to zoo workers. While there was evidence of some zoonotic transmission at Auckland Zoo, this was uncommon and risks appear to be adequately managed under current policies and procedures. Nevertheless, ongoing assessment of risk factors is needed as

Human-animal relationships in zoo-housed orangutans (P. abelii) and gorillas (G. g. gorilla): the effects of familiarity.

Smith, Joshua J

2014-10-01

I examined human-animal relationships (HARs) in zoo-housed orangutans (Pongo abelii) and gorillas (Gorilla gorilla gorilla) to see if they followed patterns similar to conspecific relationships in great apes and humans. Familiarity and social relationships guide humans' and great apes' behaviors with conspecifics. Inter-individual relationships, based on shared social history, and "generalized" relationships, based on a history of interactions with relevant classes of individuals, guide behavior with familiar and unfamiliar conspecifics, respectively. I examined whether both familiarity and social relationships similarly guides great apes' cross-species interactions with humans. I used repeated measures MANOVA to compare hourly rates and average durations of ape-initiated human-directed behaviors (HDBs) between familiar and unfamiliar humans and between great ape species. HDB patterns were consistent with familiarity-based HAR predictions, indicating more negative relationships with unfamiliar humans and more positive relationships with familiar humans. Findings for unfamiliar humans are consistent with negative effects of humans on apes' behavior reported in traditional visitor effect studies (VES). However, findings for familiar humans may be overlooked in VES due to pooling across levels of human familiarity or failure to consider humans other than primarily unfamiliar visitors. Additionally, species differences in apes' HDBs suggest that data pooling across species, common in many zoo studies, may mask important differences. These findings have important methodological implications for studies of human-animal interaction as well as for captive animal wellbeing. © 2014 Wiley Periodicals, Inc.

Searching for behavioral indicators of welfare in zoos: uncovering anticipatory behavior.

PubMed

Watters, Jason V

2014-01-01

A current focus of zoo-based research aims to identify indicators of animal welfare. Reliable behavioral indicators of welfare are highly desirable as behavioral observation is non invasive and requires little in the way of specialized equipment and other costly resources-save for observer time. Anticipatory behavior is an indicator of an animal's sensitivity to reward and as such, it is a real-time indicator of animals' own perceptions of their well-being. In fact, anticipatory behavior may generate a positive affective state and thus be at least a brief manifestation of good welfare itself. The husbandry conditions of most captive animals are such that food acquisition and other positive outcomes are highly scheduled and easily signaled. These conditions promote the development of anticipatory behavior, yet little research has either documented or interpreted this behavior in zoo and aquarium animals. This commentary suggests that anticipatory behavior could be a useful tool for assessing welfare and calls upon zoo and aquarium researchers to begin to develop this tool by describing the behavior and the circumstances that lead to its modulation. © 2014 Wiley Periodicals, Inc.

Rodents and other small wild mammals are often considered to be pests and vectors for disease in zoos that house small populations of valuable threatened and endangered animals. In 2005, three nonhuman primates at a drive-through zoo in Oregon, US, acquired tularemia from an unknown source. Due to an abundance of California ground squirrels ( Spermophilus beecheyi ) on zoo grounds, we instituted serosurveillance of this species from July through September 2008 to determine the prevalence of antibodies against pathogens considered to be potentially transmissible to collection animals. Serologic testing was performed for Francisella tularensis ; Leptospira interrogans serovars Canicola, Grippotyphosa, Hardjo, Icterohemorrhagiae, and Pomona; Toxoplasma gondii ; and Yersinia pestis . All squirrels were seronegative for Yersinia pestis (0%; 0/45) and Toxoplasma gondii (0%; 0/20); there was a prevalence of 2% (1/45) for Francisella tularensis antibodies and 57% (24/42) were positive for various Leptospira serovars. Although it remains unclear whether ground squirrels present a significant risk for transmission of disease to zoo animals, vaccination of high-risk zoo animals against leptospirosis warrants consideration. Beyond this, continued vigilance and persistence with various forms of pest control may reduce the likelihood of disease transmission from wildlife hosts to animals in human care.

Serum concentrations of amino acids, fatty acids, lipoproteins, vitamins A and E, and minerals in zoo giraffes (Giraffa camelopardalis) were compared to values obtained from free-ranging giraffes in an effort to identify potential nutritional differences in the zoo population. Zoo giraffes have a specific set of maladies that may be nutritionally related, including peracute mortality, energy malnutrition, pancreatic disease, urolithiasis, hoof disease, and severe intestinal parasitism. Dietary requirements for giraffes are not known; invasive studies used with domestic animals cannot be performed on zoo animals. Though domestic animal standards are often used to evaluate nutritional health of exotic animals, they may not be the most appropriate standards to use. Serum samples from 20 zoo giraffes at 10 zoological institutions in the United States were compared to previously collected samples from 24 free-ranging giraffes in South Africa. Thirteen of the zoo animal samples were collected from animals trained for blood collection, and seven were banked samples obtained from a previous serum collection. Dietary information was also collected on each zoo giraffe; most zoo giraffe diets consisted of alfalfa-based pellets (acid detergent fiber-16), alfalfa hay, and browse in varying quantities. Differences between zoo and free-ranging giraffes, males and females, and adults and subadults were analyzed with the use of a 2 x 2 x 2 factorial and Fisher's Least Significant Difference (LSD) for mean separation. Of the 84 parameters measured, 54 (60%) were significantly different (P < or = 0.05) between zoo and free-ranging giraffes. Nine (11%) items were significantly different (P < or = 0.05) between adult and subadult animals. Only one parameter, sodium concentration, was found to be significantly different (P < or = 0.05) between genders. Further investigation in zoo giraffe diets is needed to address the differences seen in this study and the potentially related health

To assess Cryptosporidium infections among wild animals in a zoo located in Anhui province, we conducted an investigation on the fecal samples collected from 44 primates, 41 herbivores, 44 carnivores and omnivores, and 103 birds in the zoo with the use of Sheather's sugar flotation technique and modified acid-fast staining. Cryptosporidium oocysts were detected in the fecal samples from six primates, two herbivores, four carnivores and omnivores, and seven birds by using Sheather's sugar flotation technique; the prevalence of Cryptosporidium infection in primates, herbivores, carnivores and omnivores and birds was 13.64, 4.88, 9.09, and 6.80%, respectively. Modified acid-fast staining detected the presence of Cryptosporidium oocysts in the fecal samples of one primate, three herbivores, 0 carnivores and omnivores, and one bird, and the prevalence of Cryptosporidium infection in primates, herbivores, carnivores and omnivores and birds was 2.27, 7.32, 0.00, and 0.97%, respectively. Polymerase chain reaction-restriction fragment-length polymorphism (PCR-RFLP) and phylogenetic analysis with the use of the neighbor-joining (NJ) method based on the aligned partial small-subunit (SSU) rRNA gene sequences showed that the protozoan pathogen isolated from primates was Cryptosporidium hominis and the pathogen isolated from camels ( Camelus dromedarius ) was Cryptosporidium andersoni. Subtyping the Cryptosporidium hominis by 60-kDa glycoprotein (GP60) gene phylogenetic analysis showed the Cryptosporidium hominis belongs to the subtype IdA and IbA.

Many koalas carry an endogenous retrovirus, KoRV-A, in their genome. Recently, a second retrovirus, KoRV-B, was detected in koalas in Japanese and U.S. zoos. However, this virus is not endogenous, differs in the receptor binding site of the surface envelope protein, and uses a receptor different from that of KoRV-A. We describe here a KoRV-B found in koalas at zoos in Germany and Belgium that differs slightly from that found in the Los Angeles zoo.

The increased mental stress of daily life and aging of the population are serious matters in Japan. There are many studies regarding the effects of human-animal interactions on mental and physical human health, whereas there are few studies examining the effects of visiting zoos. To determine the effect of visiting zoos on human health and quality of life, two different zoos were visited by 70 participants in Experiment 1 and 163 participants in Experiment 2. In this study we administered the WHO QOL-26 questionnaire in Japanese to assess the psychological scales of participants, and blood pressures and pulse rates were measured to assess their physical scales. We also used pedometers to count the number of steps taken during zoo visits. Both zoo visits decreased blood pressure and participants demonstrated more than 6000 steps during each visit. The quality of life sub-scale scores were improved after zoo visits.

Animals are dependent on mutualistic microbial communities that reside in their gastrointestinal track for essential physiological functions such as nutrition and pathogen resistance. The composition of microbial communities in an animal is influenced by various factors, including species, diet and geographical location. In this preliminary study, the population structure of fecal methanogens in Bactrian camels (Camelus bactrianus) from two zoos was studied using separate 16S rRNA gene libraries for each zoo. While methanogen sequences belonging to the genus Methanobrevibacter were dominant in both libraries, they showed significant differences in diversity (p=0.05) and structure (p<0.0001). Population structure analysis revealed that only two operational taxonomic units (OTUs) were shared between libraries, while two OTUs were unique to the Southwick Zoo library and seven OTUs were unique to the Potter Park Zoo library. These preliminary results highlight how methanogen population structures can vary greatly between animals of the same species maintained in captivity at different locations.

Reaction of vertebrate serum complement with different Borrelia burgdorferi sensu lato species is used as a basis in determining reservoir hosts among domesticated and wild animals. Borrelia burgdorferi sensu stricto, Borrelia garinii, and Borrelia afzelii were tested for their sensitivity to sera of exotic vertebrate species housed in five zoos located in the Czech Republic. We confirmed that different Borrelia species have different sensitivity to host serum. We found that tolerance to Borrelia infection possessed by hosts might differ among individuals of the same genera or species and is not affected by host age or sex. Of all zoo animals included in our study, carnivores demonstrated the highest apparent reservoir competency for Lyme borreliosis spirochetes. We showed that selected exotic ungulate species are tolerant to Borrelia infection. For the first time we showed the high tolerance of Siamese crocodile to Borrelia as compared to the other studied reptile species. While exotic vertebrates present a limited risk to the European human population as reservoirs for the causative agents of Lyme borreliosis, cases of incidental spillover infection could lead to successful replication of the pathogens in a new host, changing the status of selected exotic species and their role in pathogen emergence or maintenance. The question if being tolerant to pathogen means to be a competent reservoir host still needs an answer, simply because the majority of exotic animals might never be exposed to spirochetes in their natural environment.

Animal welfare monitoring is an essential part of zoo management and a legal requirement in many countries. Historically, a variety of welfare audits have been proposed to assist zoo managers. Unfortunately, there are a number of issues with these assessments, including lack of species information, validated tests and the overall complexity of these audits which make them difficult to implement in practice. The animal welfare assessment grid (AWAG) has previously been proposed as an animal welfare monitoring tool for animals used in research programmes. This computer-based system was successfully adapted for use in a zoo setting with two taxonomic groups: primates and birds. This tool is simple to use and provides continuous monitoring based on cumulative lifetime assessment. It is suggested as an alternative, practical method for welfare monitoring in zoos.

This study investigated behavioral activities (resting, moving, aggressive, social, and reproductive behavior) and fecal cortisol levels in 8 individually identified adult male blackbucks during periods of varying levels of zoo visitors (zero, low, high, and extremely high zoo visitor density). This study also elucidated whether zoo visitor density could disturb nonhuman animal welfare. This study analyzed fecal cortisol from the samples of blackbuck by radioimmunoassay and found significant differences (p < .05) for time the animals devoted to moving, resting, aggressive, reproductive, and social behavior on days with high and extremely high levels of zoo visitors. The ANOVA with Duncan's Multiple Range Test test showed that the fecal cortisol concentration was higher (p < .05) during the extremely high (137.30 ± 5.88 ng/g dry feces) and high (113.51 ± 3.70 ng/g dry feces) levels of zoo visitor density. The results of the study suggest that zoo visitor density affected behavior and adrenocortical secretion in Indian Blackbuck, and this may indicate an animal welfare problem.

Cryptosporidium represents a major cause of gastrointestinal illness in humans and animals including domestic, wild, and in captivity animals, and more than 30 validated species of Cryptosporidium are recognized as infectious to different hosts such as mammals, birds, reptiles, amphibians, and fish. Therefore, numerous investigations have been conducted worldwide in order to shed light on the epidemiology of this parasite and to explore its potential reservoirs. Few surveys, targeting humans and animals have been carried out regarding the epidemiology of Cryptosporidium spp. in France and no data are available about the circulation of this parasite in French zoological gardens. Herein, we determined the prevalence of Cryptosporidium in animals housed in two French zoos. A total of 307 fecal samples belonging to 161 species were screened by nested PCR. Overall, Cryptosporidium DNA was detected in 1.9% of the 161 species and 1% of the total number of fecal samples tested. Additionally, three Cryptosporidium species were identified: C. galli, C. andersoni, and C. tyzzeri. To our knowledge, this is the first molecular study focused on Cryptosporidium infection in captivity animals in France. This study is of interest considering the exposure of a large number of humans and animals to this waterborne protozoan, found ubiquitously in the environment.

Achieving true sustainability of zoo populations.

PubMed

Lacy, Robert C

2013-01-01

For the last 30 years, cooperative management of irreplaceable animal populations in zoos and aquariums has focused primarily on the goal of minimizing genetic decay within defined time frames, and large advances have been made in technologies to optimize genetic management of closed populations. However, recent analyses have shown that most zoo programs are not projected to meet their stated goals. This has been described as a lack of achieving "sustainability" of the populations, yet by definition a goal of managed decay is not a plan for sustainability. True sustainability requires management of the resource in manner that does not deplete its value for the future. Achieving such sustainability for many managed populations may require changing from managing isolated populations to managing populations that are part of a broader metapopulation, with carefully considered exchange between populations across a spectrum of ex situ to in situ. Managing zoo populations as components of comprehensive conservation strategies for the species will require research on determinants of various kinds of genetic, physiological, behavioral, and morphological variation and their roles in population viability, development of an array of management techniques and tools, training of population managers in metapopulation management and integrated conservation planning, and projections of impacts of management strategies on the viability of the captive populations and all populations that are interactively managed or affected. Such a shift in goals and methods would result in zoo population management being an ongoing part of species conservation rather than short-term or isolated from species conservation.

Helicobacter and Campylobacter species (spp.) colonize the gastrointestinal tract of various domesticated animals. Apart from their pathogenic significance in animals, several species are of zoonotic importance as well. For most non-domesticated animal spp., however, little is known on the presence and importance of these agents. Therefore, we investigated the presence of Helicobacter and Campylobacter spp. in marine and terrestrial zoo mammals. Faecal samples of various marine and terrestrial zoo mammals were collected from 6 different zoos in Belgium. These samples were tested for the presence of Helicobacter and Campylobacter spp. by isolation and direct demonstration of DNA using genus-specific PCRs, followed by sequencing of the obtained amplicons. Helicobacter spp. were detected in 12 and Campylobacter spp. in 5 of the 22 faecal samples from marine mammals. In 4 of 5 dolphins, H. cetorum was demonstrated, a well-known pathogen associated with gastritis and gastric ulceration in marine mammals. C. insulaenigrae was isolated from 4 of 6 sea lions and from 1 of 11 seals. To our knowledge, this is the first description of the presence of C. insulaenigrae on the European mainland. Helicobacter spp. were detected in 5 and Campylobacter spp. (mainly C. jejuni subsp. jejuni and C. coli) in 9 of the 26 faecal samples from terrestrial mammals. Potential novel enterohepatic Helicobacter spp. were detected in both marine and terrestrial zoo mammals. For the first time, the presence of several known and unknown Campylobacter and Helicobacter spp. was demonstrated in the gastrointestinal tract of various marine and terrestrial zoo mammals. Further investigation is needed on the pathogenic and zoonotic importance of these species. Copyright © 2018 Elsevier B.V. All rights reserved.

Conservation caring: measuring the influence of zoo visitors' connection to wildlife on pro-conservation behaviors.

Zoos in the 21st century are striving to make effective contributions to conservation. Although zoos are extremely popular and host over 600 million visitors worldwide, one challenge zoos face is how to effectively engage visitors and raise awareness and action for conservation. To this end, zoos commonly rely on charismatic megafauna, which have been shown to elicit a connection with zoo visitors. However, little is known about how to measure a connection to a species or how this connection may influence conservation behaviors. This study had two sequential objectives. The first was to develop a scale to measure visitors' connection to a species (Conservation Caring). The second was to investigate the relationship of Conservation Caring to pro-conservation behaviors, following a zoo experience. Pre- (n = 411) and post-visit (n = 452) responses were collected from three sites in order to assess the reliability and validity of a scale to measure Conservation Caring. Structural equation modeling was used to explore the relationship between Conservation Caring and pro-conservation behaviors. Conservation Caring was deemed a valid and reliable scale and was a strong predictor of species oriented behaviors (β = 0.62), for example, "adopting" an animal, but a weak predictor for biodiversity oriented behaviors (β = 0.07), for example, supporting sustainability policies. Results support the role zoos can play in fostering a connection to wildlife and stimulating pro-conservation behaviors. Additionally, visitors connected to a wide array of animals. On the basis of these results, zoos may recruit a wider assemblage of species as potential flagships. © 2013 Wiley Periodicals, Inc.

In July 2011, in a zoological garden in Rome, Italy, malignant catarrhal fever (MCF), a fatal, systemic disease of Artiodactyla, was suspected on the basis of neurological signs and gross lesions observed in a banteng, the first animal to die of this infection. An MCF type-specific PCR with subsequent sequencing of the PCR amplicon confirmed the aetiological agent as ovine herpesvirus-2 (OvHV-2). Biological samples were collected from the dead animals for gross, histological, bacteriological, virological and serological examinations. An epidemiological investigation was conducted to identify the source of the outbreak, as further deaths due to OvHV-2 still occurred after the removal of the acknowledged reservoirs, domestic sheep and goats. For this purpose, samples from other susceptible species and reservoir hosts were collected for virological and serological analysis. In conjunction, a retrospective sero-investigation was conducted on sera collected between 1999 and 2010 from some of the species involved in the present episode. In total, 11 animals belonging to four different species (banteng, Himalayan tahr, Nile lechwe and sika deer) died between July 2011 and October 2012. The severe gross and histological lesions were consistent with the disease, namely haemorrhages and congestion of several organs as well as lymphoid cell infiltrates and vasculitis of varying severity. The virological tests confirmed that all animals had died of sheep-associated MCF. The investigation indicated that the OvHV-2 infection could have been due to the arrival of sheep in the petting zoo, with cases commencing after first lambing and subsequent shedding of virus. This was also supported by the serological retrospective study that indicated limited previous MCF virus circulation. Further MCF cases that occurred even after the removal of the domestic sheep and goats were attributed to the mouflon. This episode confirms the importance of biosecurity measures in zoos, which house MCF

2013-01-01

Multi-institutional studies of welfare have proven to be valuable in zoos but are hampered by limited sample sizes and difficulty in evaluating more than just a few welfare indicators. To more clearly understand how interactions of husbandry factors influence the interrelationships among welfare outcomes, epidemiological approaches are needed as well as multifactorial assessments of welfare. Many questions have been raised about the housing and care of elephants in zoos and whether their environmental and social needs are being met in a manner that promotes good welfare. This article describes the background and rationale for a large-scale study of elephant welfare in North American zoos funded by the (U.S.) Institute of Museum and Library Services. The goals of this project are to document the prevalence of positive and negative welfare states in 291 elephants exhibited in 72 Association of Zoos and Aquariums zoos and then determine the environmental, management, and husbandry factors that impact elephant welfare. This research is the largest scale nonhuman animal welfare project ever undertaken by the zoo community, and the scope of environmental variables and welfare outcomes measured is unprecedented.

Investigating the impact of large carcass feeding on the behavior of captive Andean condors (Vultur gryphus) and its perception by zoo visitors.

PubMed

Gaengler, Hannah; Clum, Nancy

2015-01-01

Naturalistic feeding methods, such as the provision of whole carcasses to zoo animals, are potentially controversial because zoo visitors might not approve of them. However, since several species of zoo animals feed from large carcasses in the wild, this food type could benefit their welfare in captivity compared to other less-natural food types. Scavengers in particular almost exclusively live on carcasses in nature; therefore, their welfare in captivity could significantly depend on the opportunity to express behaviors related to carcass feeding. In this study, we assessed the frequency of carcass feeding for vultures in North American zoos and investigated the effect of different food types on the behavior of zoo-housed Andean condors (Vultur gryphus). We also evaluated the opinion of North American zoo visitors about carcass feeding. Our results show that small whole carcasses (rats, rabbits) are part of the diet of vultures in most North American zoos, but large whole carcasses (ungulates) are rarely fed. Our behavioral study indicated that Andean condors appear to be more motivated to feed on more natural food types, which also seem to physically engage the birds more and occupy them longer. Most zoo visitors approved of carcass feeding for captive vultures over a range of prey animals, and the majority would also like to observe the vultures eat. Collectively, our results demonstrate that carcass feeding, particularly with larger prey, potentially enriches both zoo-housed vultures as well as the visitor experience. © 2015 Wiley Periodicals, Inc.

An examination of environmental collective identity development across three life-stages: The contribution of social public experiences at zoos

NASA Astrophysics Data System (ADS)

Fraser, John Robert

This research breaks ground toward a revised theory of how collective environmental identity is associated with pro-environmental behaviors. My research comprises three activities that examined the experiences of three groups of people who claim zoo visiting as an important part of their life-story. The three studied groups were; conservation biologists who describe zoo experiences as having significant formative role in their childhood development of environmental values; parents who prioritize zoo visits as an important cultural experiences for their children; and a active zoo volunteers. This research also investigated whether the group experiences these participants had at zoos contributed to the value these people place on their current collective and environmental identities. Field conservationists' interest in learning from animals was validated by parents who also valued education and helped these children develop identities that included other animals in their scope of justice. Parents used zoos instrumentally to promote caring for others as a skill that will serve their children's socio-political future as part of human society. In both cases, these experiences appeared to be shaped around developing attitudes that would include animals in these children's scope of justice in later life. Zoo volunteers included animals in their scope of justice, believing that other species were also important sources of for their knowledge development. Shared positive attitudes toward animals were central to volunteers feeling part of a community and contributing to their collective self-esteem. The group may serve a restorative function in their lives, allowing them to take on a more activist role in society, seeking to promote social norms that are more inclusive of animal rights, and helping them to change their behaviors toward more environmentally responsible ends. This research contributes to the understanding of the theory of planned behavior and the values

Recognition of an important water quality issue at zoos: prevalence and potential threat of toxic cyanobacteria.

Zoo animals may be particularly vulnerable to water sources contaminated with cyanobacterial toxins given their nonvoluntary close association with this resource. However, the prevalence and potential threat of toxic cyanobacteria in this setting are unknown. Several otherwise unexplained yellow-bellied slider (Trachemys scripta scripta) deaths were documented in a zoo moat with recurring blooms of toxic Microcystis aeruginosa. Furthermore, an extremely high and potentially lethal concentration of the hepatotoxin microcystin (166 ng/g) was found in the liver of a necropsied turtle that died in this moat. A subsequent monthly survey of water quality revealed detectable concentrations of microcystin in all moats (0.0001 to 7.5 microg/L), with moats higher than 1 microg/L being significantly higher than the threshold for safe drinking water recommended by the World Health Organization. These results demonstrate that cyanobacterial blooms are an important water quality issue in zoos, and future research is necessary to identify potential associations among water quality, zoo animal health, and moat management strategies.

Lighting retrofits at the Pittsburgh Zoo and Aviary

DOE Office of Scientific and Technical Information (OSTI.GOV)

Sadowski, E.C.

Energy bills for the Pittsburgh Zoo typically total $280,000 a year, of which about $220,000 are spent on electricity. Until recently, lighting accounted for 20 percent of this electricity use. This translated into an annual cost of $44,000. Recent advances in lighting technology have made it possible to perform lighting retrofits in Zoo facilities that reduce energy costs while also providing improved light quality and better lit and more natural looking exhibits and animal holding areas. Through an investment of $127,690 in these projects from mid-1992 through mid-1994, the Zoo expects to realize an annual savings in electricity costs ofmore » $24,500 and further savings from a reduction in maintenance and plant replacement costs. Retrofits to the lighting systems in the Tropical Forest Building, the Aquarium, and the Niches of the World Building were the most interesting and are described in detail. Providing a sufficient amount of ultraviolet light to maintain the health of reptiles was a particular challenge in the Niches of the World Building. Lack of separate meters and additions to the Zoo have made the determination of the actual performance of these retrofit projects impossible. A similar retrofit project at the Pittsburgh Aviary (now the National Aviary) in 1989 through 1990 provides savings figures that should be comparable to those expected at the Zoo, however. This project cost $100,000 and saved $21,008 in electricity costs during the first year of operation. Maintenance costs were reduced by approximately $5000 a year.« less

What kinds of learning opportunities, beyond enhanced signage, can be offered to the sophisticated new breed of visitors in zoos, aquariums, and nature…

Bronx Zoo cogeneration project

Rivet, P.H.

The New York Zoological Society commenced feasibility studies for a proposed cogeneration and district heating system for the Bronz Zoo in spring 1982. Early studies focused on evaluating the Zoo's energy loads, infrastructure, and energy delivery and financing systems. The Zoological Society and New York City joined in the decision to support the construction of a system which would serve not only the Bronx Zoo but also five nearby City-funded installations, including the adjacent New York Botanical Garden. Since the submission of that study, the project has been modified in scope, scaling back to a generating capacity designed to servemore » only the Bronz Zoo.« less

The significance of petting zoos for transmission of Campylobacter to humans and the effect of interventions were estimated. A stochastic QMRA model simulating a child or adult visiting a Dutch petting zoo was built. The model describes the transmission of Campylobacter in animal feces from the various animal species, fences, and the playground to ingestion by visitors through touching these so-called carriers and subsequently touching their lips. Extensive field and laboratory research was done to fulfill data needs. Fecal contamination on all carriers was measured by swabbing in 10 petting zoos, using Escherichia coli as an indicator. Carrier-hand and hand-lip touching frequencies were estimated by, in total, 13 days of observations of visitors by two observers at two petting zoos. The transmission from carrier to hand and from hand to lip by touching was measured using preapplied cow feces to which E. coli WG5 was added as an indicator. Via a Beta-Poisson dose-response function, the number of Campylobacter cases for the whole of the Netherlands (16 million population) in a year was estimated at 187 and 52 for children and adults, respectively, so 239 in total. This is significantly lower than previous QMRA results on chicken fillet and drinking water consumption. Scenarios of 90% reduction of the contamination (meant to mimic cleaning) of all fences and just goat fences reduces the number of cases by 82% and 75%, respectively. The model can easily be adapted for other fecally transmitted pathogens. © 2014 Society for Risk Analysis.

This paper describes a new project of the Institute for Geoinformatics and Remote Sensing, funded by the German Federal Foundation for the Environment (DBU, Deutsche Bundesstiftung Umwelt www.dbu.de). The goal of this project is to develop a mobile zoo information system for Pocket PCs and Smart phones. Visitors of the zoo will be able to use their own mobile devices or use Pocket PCs, which could be borrowed from the zoo to navigate around the zoo's facilities. The system will also provide additional multimedia based information such as audio-based material, animal video clips, and maps of their natural habitat. People could have access to the project at the zoo via wireless local area network or by downloading the necessary files using a home internet connection. Our software environment consists of proprietary and non-proprietary software solutions in order to make it as flexible as possible. Our first prototype was developed with Visual Studio 2003 and Visual Basic.Net.

The rate of occurrence of hepatitis A and B virus specific markers in anthropoid apes of the Moscow Zoo (3 chimpanzees, 3 gorillas, 8 orang-outangs) was studied. Long-term persistence of HBs-antigen in orang-outang accompanied by the presence of HBe-antigen and anti-HBs was demonstrated. The presence of anti-HBs in gorillas and orang-outangs was recorded. Antibodies to hepatitis A virus were found in all the animal species examined. Cases of acute virus hepatitis A in orang-outangs are described contracted from the personnel handling the animals and suffering from this type of hepatitis. Morphological features of the course of hepatitis A in the presence of HBs-antigen carrier state are described. The possibility of active immunization of susceptible animals and the personnel of the zoo against viral hepatitides is discussed.

Zoo theater's influence on affect and cognition: a case study from the Central Park Zoo in New York.

Penn, Laura

2009-09-01

Zoo theater is used by zoos as a means to influence visitor feelings and knowledge gain about wildlife and environmental themes. This study examined whether and to what extent zoo theater fulfilled these aims by investigating its impact on affect and cognition. The study consisted of an in-depth case study at the Central Park Zoo in New York, a location that has one of the most diverse zoo theater programs in the United States. Using a multimethod approach the study explored many facets of the Central Park Zoo's extensive zoo theater program. These included performances at a main stage, at exhibits, and in the children's zoo. The study found that the extent of zoo theater's influence on affect and cognition is dependent on a combination of a variety of characteristics that include the length of a performance, audience participation, the level of structure of a performance, the presence of song and dance elements, and the scale of the productions.

The pollutant loads of surface runoff in an urban tourist area have been investigated for two years in the Wuhan City Zoo, China. Eight sampling sites, including two woodlands, three animal yards, two roofs and one road, were selected for sampling and study. The results indicate that pollutants ranked in a predictable order of decreasing load (e.g. animal yard > roof > woodland > road), with animal yards acting as the key pollution source in the zoo. Pollutants were transported mainly by particulate form in runoff. Particulate nitrogen and particulate phosphorous accounted on average for 61%, 78% of total pollutant, respectively, over 13 monitored rainfall events. These results indicate the treatment practices should be implemented to improve particulate nutrient removal. Analysis of the M(V) curve indicate that no first flush effect existed in the surface runoff from pervious areas (e.g. woodland, animal ground yard), whereas a first flush effect was evident in runoff from impervious surfaces (e.g. animal cement yard, roof, road).

Little is known about the characteristics and diseases associated with methicillin-resistant Staphylococcus aureus (MRSA) in nondomestic animals. Four presumptive MRSA isolates, obtained from clinical (n = 3) and surveillance specimens (n = 1) from dwarf (Helogale parvula) and yellow mongooses (Cynictis penicillata) from a United Kingdom zoo, were analyzed by PCR for detection of mecA and mecC-mediated methicillin resistance, and virulence genes. Isolates were genotyped by multilocus sequence typing (MLST) and staphylococcal cassette chromosome mec (SCCmec) and spa sequence typing. Three isolates, obtained from the dwarf mongooses, carried mecA, tetK, and fexA resistance and virulence genes (icaA, icaD, and sec) and were typed to SCCmec IVa, spa type t899, and clonal complex (CC) 398. The fourth MRSA isolate, obtained from the femoral bone marrow of a yellow mongoose showing postmortem findings consistent with septicemia, carried mecC and was oxacillin/cefoxitin susceptible, when tested at 37°C but showed a characteristic MRSA susceptibility profile at 25°C ± 2°C. Furthermore, this isolate exhibited a different genetic background (SCCmecXI/t843/CC130) and had biofilm-associated genes (bap, icaA, and icaD) and tetK tetracycline resistance genes. This work describes the first isolation of livestock-associated MRSA CC398 from two zoo mongoose species where it was associated with both clinical disease and colonization, and the first isolation of mecC MRSA from a zoo species in the United Kingdom. Both reports highlight the potential for zoo species to act as reservoirs for these zoonotic agents.

Zoos and zoologic gardens make optimal environments for interspecies transmission of viral infections. There are seven zoos and several small zoologic collections in Turkey. This study aimed to determine the current status of viral infections in captive ungulates living in these environments. Blood samples were taken from 163 captive animals from two zoos. There were 39 Cameroon sheep (Ovis ammon f aries), 11 Barbary sheep (Ammotragus lervia), 57 pygmy goats (Capra hircus), 9 Angora goats (Capra hircus), 21 mountain goats (Capra aegagrus-aegagrus), 7 llamas (Lama glama), 8 Persian goitred gazelle (Gazella subgutturosa subgutturosa), 7 Caspian red deer (Cervus elaphus maral), 2 fallow deer (Dama dama), and 2 camels (Camelus dromedarius). Antibodies against bovine viral diarrhea virus (BVDV), bovine herpesvirus-1 (BHV-1), bovine adenoviruses (BAV-1 and -3), parainfluenzavirus 3 (PI-3), and bluetongue viruses (BTV-4 and -9) were investigated using the virus neutralization test, and malignant catarrhal fever (MCF) antibodies were screened by ELISA. All animals were negative for BVDV and BHV-1 antibodies. Seroprevalence of BAV-1, BAV-3, PI-3, BRSV, BT-4, BT-9, and MCF were detected as follows: 46.6%, 60.1%, 0.6%, 7.3%, 1.8%, 1.2%, and 51.6%, respectively. Seroprevalence of BAVs and MCF were more common than all other viruses (P < 0.0001). Ten sheep (37.0%), 48 goats (84.2), and 1 Ilama (14.2%) were the only species positive for MCF antibodies. Prevalence of BRSV and MCF antibodies were found to be significantly higher in goats than in sheep. BTV antibodies were detected both in Cameroon sheep and mountain goats and suggest that zoo animals are at risk for BTV in endemic regions.

Clinically healthy reptiles may shed Salmonella and therefore act as a potential zoonotic threat. Most people in Northern European countries are rarely exposed to reptiles, but many zoos have education departments where children have direct contact with this group of animals. The objectives of this study were to determine the prevalence and serotype distribution of Salmonella among reptiles in the Education Department (n = 55) at Copenhagen Zoo and compare it to the Zoo's main reptile collection (n = 145) to evaluate the zoonotic risk. Salmonella was isolated from cloacal swabs by selective enrichment, and a single isolate from each positive sample was further identified by biochemical tests and serotyped. The overall prevalence was 35% (69/200) with significant difference between the Education Department (64%, 35/55) and the main reptile collection (23%, 34/145). A total of 28 serotypes were detected. Ten serotypes were isolated from more than one specimen and four from more than one species. Salmonella enterica subsp. enterica serovar Eastbourne was the predominant serotype (32%, 22/69) and was also the serotype isolated from most reptile species (n = 7). Transmission of serotypes from one department to another was very limited indicated by the serotype distribution. Despite the relative high prevalence observed among the reptiles in the Zoo's Education Department compared to the reptiles in the Zoo's main reptile collection, no Salmonella cases have been linked to the Zoo, and Salmonella ser. Eastbourne is very rarely isolated from humans in Denmark. Simple hygienic procedures such as hand washing which is consistently carried out following handling of reptiles at the Education Department may reduce the risk and therefore contribute to this low prevalence. © 2012 Blackwell Verlag GmbH.

Life expectancy and longevity of varanid lizards (Reptilia:Squamata:Varanidae) in North American zoos.

Mendyk, Robert W

2015-01-01

In zoos, life expectancy-the average lifespan of individuals within a population, and longevity-the maximum lifespan within a population, can be useful parameters for evaluating captive husbandry and animal welfare. Using life history and demographic data derived from regional studbooks, this study examined life expectancy and longevity in a total of 782 wild-caught (WC) and captive-bred (CB) varanid lizards of seven species maintained in North American zoos since 1926. The average lifespans for WC and CB animals were 6.3 ± 0.3 and 9.3 ± 0.4 years, respectively, with CB males living significantly longer than females (P = 0.009). A total of 26.4% of WC and 22.5% of CB animals experienced mortality during their first 2 years in captivity, with mortality during this period greatest among Varanus rudicollis and V. prasinus. A positive correlation was observed between life expectancy and adult body mass in captive-bred individuals (r = 0.981; P = 0.002). Wild-caught females with a history of successful reproduction had a significantly greater average lifespan than non-reproducing females (P < 0.0001). Results from this study suggest that varanids have not been reaching their lifespan capacities in North American zoos. In light of these findings, several husbandry-related factors which may be affecting the welfare and lifespans of varanids in zoos are identified and discussed. This study also highlights the utility of demographic and life history data in captive animal management, and offers a general framework for future herpetological studies of a similar nature. © 2014 Wiley Periodicals, Inc.

Clostridium difficile is an emerging and potentially zoonotic pathogen, but its prevalence in most animal species, including exhibition animals, is currently unknown. In this study we assessed the prevalence of faecal shedding of C. difficile by zoo animals, and determined the ribotype, toxin profile and antimicrobial susceptibility of recovered isolates. A total of 200 samples from 40 animal species (36.5% of which came from plains zebra, Equus quagga burchellii) were analysed. C. difficile was isolated from 7 samples (3.5% of total), which came from the following animal species: chimpanzee (Pan troglodytes troglodytes), dwarf goat (Capra hircus), and Iberian ibex (Capra pyrenaica hispanica), with one positive sample each; and plains zebra, with 4 positive samples from 3 different individuals. Most recovered isolates (4/7, 57.1%) belonged to the epidemic PCR ribotype 078, produced toxins A and B, and had the genes encoding binary toxin (i.e. A(+)B(+)CDT(+) isolates). The remaining three isolates belonged to PCR ribotypes 039 (A(-)B(-)CDT(-)), 042 (A(+)B(+)CDT(-)) and 110 (A(-)B(+)CDT(-)). Regardless of their ribotype, all isolates displayed high-level resistance to the fluoroquinolones ciprofloxacin, enrofloxacin and levofloxacin. Some isolates were also resistant to meropenem and/or ertapenem. A ribotype 078 isolate recovered from a male zebra foal initially showed in vitro resistance to metronidazole (MIC ≥ 256 μg/ml), but lost that trait after subculturing on non-selective media. We conclude that zoo animals belonging to different species can carry ribotype 078 and other toxigenic strains of C. difficile showing resistance to antimicrobial compounds commonly used in veterinary and/or human medicine.

Zoos in the twenty-first century: Can't we find a better way to love nature?

NASA Astrophysics Data System (ADS)

Dewey-Platt, Lauren Kay

As a new millennium approaches, many forms of life on the planet and the environments in which they have evolved are increasingly threatened by human activities Wildlife is being marginalized, and native habitats are disappearing at an unprecedented rate. Equally disturbing is the impending demise of traditional human societies---peoples who have evolved outside of the confines and conditions of modern Western influence. The loss of these human and animal societies has occurred so rapidly that implications are largely unknown. Research on how modern Americans relate to animals, particularly wildlife, revealed a clear and disturbing incongruity best exemplified in the current paradigm of zoo exhibition and education. Although zoos purport to educate visitors about the ecology of natural environments and the universal plight of wildlife, research shows that people, particularly children, learn less about ecological principles in zoos with live animals than they do in non-living natural history exhibits. While designers employ a variety of visual techniques in natural history exhibition, environmental sound as an educational exhibit component is largely nonexistent. Many animal species communicate through sound, especially species in underwater environments. As the audio equivalent of a landscape, the soundscape is as important as any other habitat feature to the well-being of wildlife populations. Using recorded sounds of natural environments, an exhibition soundscape was designed and produced for Oceanario de Lisboa in Lisbon, Portugal---the centerpiece of the 1998 World Exposition in Lisbon, Portugal. With programmed sound serving as a major component of natural history exhibition, a conceptual design of a novel zoo for the twenty-first century was described. The "NewZew" concept is based on a growing awareness that the best way to save species is to salvage, preserve, and restore their natural habitats---activities that are largely antithetical to current zoo

The use of modern electronic media offers new ways of (environmental) knowledge transfer. All kind of information can be made quickly available as well as queryable and can be processed individually. The Institute for Geoinformatics and Remote Sensing (IGF) in collaboration with the Osnabrueck Zoo, is developing a zoo information system, especially for new media (e.g. mobile devices), which provides information about the animals living there, their natural habitat and endangerment status. Thereby multimedia information is being offered to the zoo visitors. The implementation of the 2D/3D components is realized by modern database and Mapserver technologies. Among other technologies, the VRML (Virtual Reality Modeling Language) standard is used for the realization of the 3D visualization so that it can be viewed in every conventional web browser. Also, a mobile information system for Pocket PCs, Smartphones and Ultra Mobile PCs (UMPC) is being developed. All contents, including the coordinates, are stored in a PostgreSQL database. The data input, the processing and other administrative operations are executed by a content management system (CMS).

Role of Brazilian zoos in ex situ bird conservation: from 1981 to 2005.

2011-01-01

Zoos may play an important role in conservation when they maintain and breed large numbers of animals that are threatened with extinction. Bird conservation is in a privileged situation owing to the extensive biological information available about this class. Annual inventories produced by the "Sociedade de Zoológicos do Brasil" in the years 1981, 1990, 2000, and 2005 were analyzed. Variables, such as the number of zoos per geographic region; number of birds held; number of bird species in each IUCN threat category; number of exotic and native bird species; number of potentially breeding bird species; number of bird species in each order; and number of threatened bird species breeding, were analyzed. Brazilian zoos kept more than 350 bird species. The number of bird species and specimens held by the Brazilian Zoos increased from 1981 to 2000, but decreased in 2005. The same pattern was observed for the number of species in each IUCN threat category. Results showed that the potential of the Brazilian zoos in bird conservation needs to be enhanced because they maintain threatened species but do not implement systematic genetic, reproductive, or behavioral management protocols for most species. © 2010 Wiley Periodicals, Inc.

Is wounding aggression in zoo-housed chimpanzees and ring-tailed lemurs related to zoo visitor numbers?

Chimpanzees in laboratory colonies experience more wounds on weekdays than on weekends, which has been attributed to the increased number of people present during the week; thus, the presence of more people was interpreted as stressful. If this were also true for primates in zoos, where high human presence is a regular feature, this would clearly be of concern. Here we examine wounding rates in two primate species (chimpanzees Pan troglodytes and ring-tailed lemurs Lemur catta) at three different zoos, to determine whether they correlate with mean number of visitors to the zoo. Wounding data were obtained from a zoo electronic record keeping system (ZIMS™). The pattern of wounds did not correlate with mean gate numbers for those days for either species in any group. We conclude that there is no evidence that high visitor numbers result in increased woundings in these two species when housed in zoos.

Given current extinction trends, the number of species requiring conservation breeding programs (CBPs) is likely to increase dramatically. To inform CBP policies for threatened terrestrial vertebrates, we evaluated the number and representation of threatened vertebrate species on the IUCN Red List held in the ISIS zoo network and estimated the complexity of their management as metapopulations. Our results show that 695 of the 3,955 (23%) terrestrial vertebrate species in ISIS zoos are threatened. Only two of the 59 taxonomic orders show a higher proportion of threatened species in ISIS zoos than would be expected if species were selected at random. In addition, for most taxa, the management of a zoo metapopulation of more than 250 individuals will require the coordination of a cluster of 11 to 24 ISIS zoos within a radius of 2,000 km. Thus, in the zoo network, the representation of species that may require CBPs is currently low and the spatial distribution of these zoo populations makes management difficult. Although the zoo community may have the will and the logistical potential to contribute to conservation actions, including CBPs, to do so will require greater collaboration between zoos and other institutions, alongside the development of international agreements that facilitate cross-border movement of zoo animals. To maximize the effectiveness of integrated conservation actions that include CBPs, it is fundamental that the non-zoo conservation community acknowledges and integrates the expertise and facilities of zoos where it can be helpful.

2009-03-01

The quantitative assessment of the status of soils in Moscow Zoo was performed using traditional and original methods based on the differentiated system of indices. The studies were conducted in animal open-air cages and on plots available for visitors. The dynamics of the temperature and water-air regimes in the root-inhabited layer, the density, the acidity, and the salinity of the soils were studied. The level of the biological activity was assessed according to the intensity of the organic matter decomposition and the substrate-induced respiration. In the background of the rather satisfactory status of the soils, negative factors were found: a periodic excess or deficit of moisture and, for the most part, low biological activity (low respiration and decomposition of the lignin-cellulose test material). Recommendations for the improvement of the status of the soil cover in Moscow Zoo are proposed.

Behavioral thermoregulation in a group of zoo-housed colobus monkeys (Colobus guereza).

2014-01-01

Although wild primates are known to modify behavior in response to thermal stress, less is known about behavioral thermoregulation in zoo-housed primates. Zoo exhibits expose individuals to unique thermal environments and may constrain the thermoregulatory strategies available to individual animals. In this study, we observed a group of seven colobus monkeys (Colobus guereza) living on a concrete "Monkey Island" style exhibit that featured limited shade and limited arboreal space. Behaviors were recorded using continuous focal animal sampling (n = 63 days, 97.7 hr). Logistic regression revealed 23°C was the temperature at which monkeys began resting more in shade than in sun. When temperatures exceeded 23°C, animals spent more time in open sitting postures with limbs extended from the body; sat less frequently in closed, hunched postures; spent more time in social contact; and performed more self-directed behaviors. Exhibit use also shifted under higher temperatures, with more time spent in areas with shade and lower surface temperatures. Lastly, when provided with access to an indoor holding area, the colobus monkeys spent more than half the time indoors when temperatures exceeded 23°C, yet only 10% of their time indoors when the temperature was below this value. Although postural changes have been reported in wild colobus, the postural and other behavioral changes observed in the current study occurred at temperatures lower than expected based on the published thermoneutral zone of colobus monkeys and highlight the importance of considering the specific thermoregulatory responses of zoo animals. © 2014 Wiley Periodicals, Inc.

Vohra, Rais; Clark, Rick; Shah, Nilofar

2008-11-01

To characterize occupational envenomations from exotic and native creatures, we surveyed North American zoos and aquaria. Survey questionnaires were mailed to curators at 216 zoos/aquaria which are accredited by the Association of Zoos and Aquariums (AZA) and listed on the AZA website. Reptile curators were asked to complete the zoo surveys. The questions addressed the number and types of bites, availability of antivenom (AV) on the premises, and sources of general information about envenoming. Responses were kept anonymous. A total of 216 surveys were mailed. The response rate was 58% for this pilot research project. Twenty-six (21%) of responding institutions replied that they had at least one incident of bite from a venomous species in the last 10 years. Species of animals included a variety of native and exotic terrestrial and marine species. There were no deaths or serious outcomes reported as complications of these incidents. Less than one-third of responding institutions reported having AVs on-site for medical use in case of envenomations. A variety of information sources, including internally developed protocols and poison center resources, were reported as sources of envenoming information for respondents. Clinicians and toxicologists should be prepared to care for cases of envenomations from exotic zoo or aquarium species such as the ones identified in this survey in their practice regions.

The occurrence of a coccidian parasite, Cryptosporidium, among birds in the Kuala Lumpur National Zoo was investigated in this study. A hundred bird fecal samples were taken from various locations of the zoo. Fecal smears prepared using direct smear and formalin ethyl acetate concentration technique were stained with modified Ziehl-Neelsen stain. Samples positive for Cryptosporidium with Ziehl-Neelsen stain were later confirmed using the immunofluorescence technique and viewed under the epifluorescence microscope. Six species of bird feces were confirmed positive with Cryptosporidium oocysts. They included Wrinkled Hornbill (Aceros corrugatus), Great Argus Pheasant (Argusianus argus), Black Swan (Cygnus atratus), Swan Goose (Anser cygnoides), Marabou Stork (Leptoptilos crumeniferus), and Moluccan Cockatoo (Cacatua moluccencis). These birds were located in the aviary and lake, with the Moluccan Cockatoo routinely used as a show bird. Results obtained in this study indicated that animal sanctuaries like zoos and bird parks are important sources of Cryptosporidium infection to humans, especially children and other animals.

Quarantine is designed primarily to prevent the introduction of transmissible diseases to zoological collections. Improvements in preventive medicine, disease eradication, and comprehensive pathology programs call into question current industry quarantine standards. Disease risk analysis was used at the San Diego Zoo (SDZ) and the SDZ Safari Park to eliminate quarantine isolation and transmissible disease testing for animals transferred between the two institutions. To determine if a risk-based approach might be valid between other institutions and SDZ, we reviewed quarantine data for animals arriving at SDZ from 81 Association of Zoos and Aquariums (AZA)-accredited and 124 other sources (e.g., non-AZA-accredited institutions, private breeders, private dealers, governmental bodies) over a 5-yr period (2009-2013). No mammal or herptile failed quarantine due to transmissible diseases of concern. Approximately 2.5% of incoming birds failed quarantine due to transmissible disease; however, all 14 failed individuals were obtained from three nonaccredited sources (private breeders, confiscation). The results of our study suggest that a risk-based approach could be used to minimize or eliminate quarantine for the transfer of animals from institutions with comprehensive disease surveillance programs and/or preshipment testing practices. Quarantine isolation with testing remains an essential defense against introducing transmissible diseases of concern when there is a lack of health knowledge about the animals being received.

When the Galaxy Zoo website calling for citizen scientists around the world to help classify galaxies from the Sloan Digital Sky Survey was launched, it brought down the servers hosting the images. The Galaxy Zoo tapped into the incredible desire of the public to get involved in and contribute to scientific research. With the he help of over a quarter million citizen scientists, we were able to map out the evolution of galaxy populations from star formation to quiescence and how this "quenching" is related to changes in morphology. Citizen scientists also discovered unusual objects in public data, such as "Hanny's Voorwerp", a quasar light echo which can constrain black hole accretion on timescales of 10-100 kyr. Finally, the work of citizen scientists taking part in Galaxy Zoo points to a future where machine learning and humans both contribute to systems capable of analyzing extremely large data sets.

Preference assessments in the zoo: Keeper and staff predictions of enrichment preferences across species.

Mehrkam, Lindsay R; Dorey, Nicole R

Environmental enrichment is widely used in the management of zoo animals, and is an essential strategy for increasing the behavioral welfare of these populations. It may be difficult, however, to identify potentially effective enrichment strategies that are also cost-effective and readily available. An animal's preference for a potential enrichment item may be a reliable predictor of whether that individual will reliably interact with that item, and subsequently enable staff to evaluate the effects of that enrichment strategy. The aim of the present study was to assess the utility of preference assessments for identifying potential enrichment items across six different species--each representing a different taxonomic group. In addition, we evaluated the agreement between zoo personnel's predictions of animals' enrichment preferences and stimuli selected via a preference assessment. Five out of six species (nine out of 11 individuals) exhibited clear, systematic preferences for specific stimuli. Similarities in enrichment preferences were observed among all individuals of primates, whereas individuals within ungulate and avian species displayed individual differences in enrichment preferences. Overall, zoo personnel, regardless of experience level, were significantly more accurate at predicting least-preferred stimuli than most-preferred stimuli across species, and tended to make the same predictions for all individuals within a species. Preference assessments may therefore be a useful, efficient husbandry strategy for identifying viable enrichment items at both the individual and species levels. © 2015 Wiley Periodicals, Inc.

Salivary samples were collected over a 24-hr period from one group of six juvenile (7-12 years) and one group of three adult (24-25 years) African elephant females, Loxodonta africana, and the cortisol concentration was measured in unextracted samples by EIA. Samples were collected during May, June, and November 2012 (n = 147) using cotton swabs at 4-hr intervals from 20:00 to 20:00 of the next day (seven samples per animal in each trial). The animals are kept under standard zoo management: the herd is maintained in their indoor enclosures until 10:00 and then released into the outdoor enclosures until 21:00-21:30 (May/June) and 18:30-19:00 (November). No adult elephant bull was present at the zoo during this time. The results demonstrate a clear diurnal pattern of cortisol secretion with the lowest concentration observed at 20:00 (2.03 ± 0.08 ng/ml saliva) and the peak concentrations at 08:00 (5.26 ± 0.35 ng/ml saliva). Although the cortisol values were higher in the adult cows compared to the juvenile cows in the May-June period, the differences were not significant. However, the values obtained in November from the juvenile group were significantly higher (P < 0.05) than the concentrations measured in this group in June. In conclusion, salivary cortisol in zoo elephants follows a circadian rhythm (sleep-wake cycle) adapted to daily zoo husbandry routines. © 2016 Wiley Periodicals, Inc.

Seal Formation Mechanism Beneath Animal Waste Holding Ponds

NASA Astrophysics Data System (ADS)

Cihan, A.; Tyner, J. S.; Wright, W. C.

2005-12-01

Infiltration of animal waste from holding ponds can cause contamination of groundwater. Typically, the initial flux from a pond decreases rapidly as a seal of animal waste particulates is deposited at the base of the pond. The purpose of this study was to investigate the mechanism of the seal formation. Twenty-four soil columns (10-cm diameter by 43-cm long) were hand-packed with sand, silty loam or clay soils. A 2.3 m column of dairy or swine waste was applied to the top of the each column. The leakage rate from each column was measured with respect to time to analyze the effect of seal formation on different soil textures and animal waste types. We tested our hypothesis that seal growth and the subsequent decrease of leachate production adheres to a filter cake growth model. Said model predicts that the cumulative leakage rate is proportional to the square root of time and to the square root of the height of the waste.

A survey of diabetes prevalence in zoo-housed primates.

Kuhar, C W; Fuller, G A; Dennis, P M

2013-01-01

In humans, type II diabetes mellitus is a condition in which the pancreas is capable of producing insulin but cells do not appropriately respond to insulin with an uptake of glucose. While multiple factors are associated with type II diabetes in humans, a high calorie diet and limited exercise are significant risk factors for the development of this disease. Zoo primates, with relatively high caloric density diets and sedentary lifestyles, may experience similar conditions that could predispose them to the development of diabetes. We surveyed all Association of Zoos and Aquariums (AZA) facilities with primates in their collections to determine the prevalence of diabetes, diagnosis and treatment methods, and treatment outcomes. Nearly 30% of responding institutions reported at least one diabetic primate in their current collection. Although the majority of reported cases were in Old World Monkeys (51%), all major taxonomic groups were represented. Females represented nearly 80% of the diagnosed cases. A wide variety of diagnosing, monitoring, and treatment techniques were reported. It is clear from these results diabetes should be considered prominently in decisions relating to diet, weight and activity levels in zoo-housed primates, as well as discussions surrounding animal health and welfare. © 2012 Wiley Periodicals, Inc.

While it is commonly believed that animals live longer in zoos than in the wild, this assumption has rarely been tested. We compared four survival metrics (longevity, baseline mortality, onset of senescence and rate of senescence) between both sexes of free-ranging and zoo populations of more than 50 mammal species. We found that mammals from zoo populations generally lived longer than their wild counterparts (84% of species). The effect was most notable in species with a faster pace of life (i.e. a short life span, high reproductive rate and high mortality in the wild) because zoos evidently offer protection against a number of relevant conditions like predation, intraspecific competition and diseases. Species with a slower pace of life (i.e. a long life span, low reproduction rate and low mortality in the wild) benefit less from captivity in terms of longevity; in such species, there is probably less potential for a reduction in mortality. These findings provide a first general explanation about the different magnitude of zoo environment benefits among mammalian species, and thereby highlight the effort that is needed to improve captive conditions for slow-living species that are particularly susceptible to extinction in the wild.

Ecological ethics in captivity: balancing values and responsibilities in zoo and aquarium research under rapid global change.

PubMed

Minteer, Ben A; Collins, James P

2013-01-01

Ethical obligations to animals in conservation research and management are manifold and often conflicting. Animal welfare concerns often clash with the ethical imperative to understand and conserve a population or ecosystem through research and management intervention. The accelerating pace and impact of global environmental change, especially climate change, complicates our understanding of these obligations. One example is the blurring of the distinction between ex situ (zoo- and aquarium-based) conservation and in situ (field-based) approaches as zoos and aquariums become more active in field conservation work and as researchers and managers consider more intensive interventions in wild populations and ecosystems to meet key conservation goals. These shifts, in turn, have consequences for our traditional understanding of the ethics of wildlife research and management, including our relative weighting of animal welfare and conservation commitments across rapidly evolving ex situ and in situ contexts. Although this changing landscape in many ways supports the increased use of captive wildlife in conservation-relevant research, it raises significant ethical concerns about human intervention in populations and ecosystems, including the proper role of zoos and aquariums as centers for animal research and conservation in the coming decades. Working through these concerns requires a pragmatic approach to ethical analysis, one that is able to make trade-offs among the many goods at stake (e.g., animal welfare, species viability, and ecological integrity) as we strive to protect species from further decline and extinction in this century.

These guidelines for veterinary medical care and veterinary hospitals are written to conform with the requirements of the Animal Welfare Act, which states that programs of disease prevention and parasite control, euthanasia, and adequate veterinary care shall be established and maintained under the supervision of a veterinarian. Ideally the zoo and aquarium should be providing the best possible veterinary medical care for the animals in their collections. Many of these animals are rare and endangered and the institutions should endeavor both to provide for the long term health and well being of these animals and to advance the field of non-domestic animal medicine. It is hoped that this publication will aid in this process.

2016-01-01

A two-step catalytic process for the production of biodiesel from waste frying oil (WFO) at low cost, utilizing waste animal-bone as catalyst and solar radiation as heat source is reported in this work. In the first step, the free fatty acids (FFA) in WFO were esterified with methanol by a catalytic process using calcined waste animal-bone as catalyst, which remains active even after 10 esterification runs. The trans-esterification step was catalyzed by NaOH through thermal activation process. Produced biodiesel fulfills all the international requirements for its utilization as a fuel. A probable reaction mechanism for the esterification process is proposed considering the presence of hydroxyapatite at the surface of calcined animal bones. Copyright © 2015 Elsevier Ltd.

Arsenic: a roadblock to potential animal waste management solutions.

PubMed

Nachman, Keeve E; Graham, Jay P; Price, Lance B; Silbergeld, Ellen K

2005-09-01

The localization and intensification of the poultry industry over the past 50 years have incidentally created a largely ignored environmental management crisis. As a result of these changes in poultry production, concentrated animal feeding operations (CAFOs) produce far more waste than can be managed by land disposal within the regions where it is produced. As a result, alternative waste management practices are currently being implemented, including incineration and pelletization of waste. However, organic arsenicals used in poultry feed are converted to inorganic arsenicals in poultry waste, limiting the feasibility of waste management alternatives. The presence of inorganic arsenic in incinerator ash and pelletized waste sold as fertilizer creates opportunities for population exposures that did not previously exist. The removal of arsenic from animal feed is a critical step toward safe poultry waste management.

Myiasis is a major disease condition in human and veterinary medicine. Domestic, free-ranging, and zoo-housed animals can be severely affected by myiasis. Depending on case severity, multiple treatment episodes may be indicated and can lead to recurrent capturing, handling stress, and anesthetics, all of which increase the risk of adverse responses (including death) individually and also in the herd. As an insecticide, ivermectin is often used for larval control. A total of 28 individual myiasis cases were retrospectively evaluated, out of which 11 cases were also treated using an ivermectin sustained-release varnish (SRV). The clinical outcome of all cases was assessed and the results suggest that the use of a topical ivermectin SRV (with or without concurrent injectable ivermectin) can reduce handling and treatments, has no adverse effects, and has minimal recurrence of the disease when compared with cases treated without it.

Quantifying the impact of Wellington Zoo's persuasive communication campaign on post-visit behavior.

2015-01-01

Zoos potential to facilitate visitor conservation behavior is commonly articulated. Few studies, however, have quantified whether zoos' conservation messages result in visitors implementing the behavior. To test if zoo conservation messages are adopted at home, I implemented a persuasive communication campaign which advocated keeping cats indoor at night, a behavior that is a potential solution to cats depredating native wildlife. Furthermore, I tested if a public commitment (signing a pledge card) strengthened the relationship between on-site intention to engage in the behavior and actual implementation of the behavior at home. The conservation behavior was included in the twice-daily animal presentations in the amphitheater. A sample of 691 visitors completed a survey as they exited the amphitheater that measured their recall of the conservation behavior and intention to engage in the behavior at home. The last 311 visitors to complete the survey were asked to sign a pledge card which was publicly displayed in the amphitheater. Six weeks after their zoo trip, visitors were contacted and asked if they had implemented the behavior. Recall of the conservation behavior was high (91% for control, 100% for pledge group) and the entire pledge group had implemented the behavior whereas just half (51%) of the control group did. Furthermore, signing the pledge card strengthened the relationship between onsite intention and at home behavior (r = 1.0 of for the pledge group and r = 0.21 for the control group). Overall, the zoo's conservation message was recalled and behavior implemented at home. © 2015 Wiley Periodicals, Inc.

Blastocystis sp. is a common intestinal parasite infecting humans and a wide range of animals worldwide. It exhibits an extensive genetic diversity and 17 subtypes (STs) have thus far been identified in mammalian and avian hosts. Since several STs are common to humans and animals, it was proposed that a proportion of human infections may result from zoonotic transmission. However, the contribution of each animal source to human infection remains to be clarified. Therefore, the aim of this study was to expand our knowledge of the epidemiology and host specificity of this parasite by performing the largest epidemiological survey ever conducted in animal groups in terms of numbers of species screened. A total of 307 stool samples from 161 mammalian and non-mammalian species in two French zoos were screened by real-time PCR for the presence of Blastocystis sp. Overall, 32.2% of the animal samples and 37.9% of the species tested were shown to be infected with the parasite. A total of 111 animal Blastocystis sp. isolates were subtyped, and 11 of the 17 mammalian and avian STs as well as additional STs previously identified in reptiles and insects were found with a varying prevalence according to animal groups. These data were combined with those obtained from previous surveys to evaluate the potential risk of zoonotic transmission of Blastocystis sp. through the comparison of ST distribution between human and animal hosts. This suggests that non-human primates, artiodactyls and birds may serve as reservoirs for human infection, especially in animal handlers. In contrast, other mammals such as carnivores, and non-mammalian groups including reptiles and insects, do not seem to represent significant sources of Blastocystis sp. infection in humans. In further studies, more intensive sampling and screening of potential new animal hosts will reinforce these statements and expand our understanding of the circulation of Blastocystis sp. in animal and human populations.

Bovine Viral Diarrhea Virus in Zoos: A Perspective from the Veterinary Team

PubMed Central

Kottwitz, Jack J.; Ortiz, Melissa

2016-01-01

The many different species in close proximity make zoological collections a unique environment for disease transmission. Bovine Viral Diarrhea Virus (BVDV) is of special concern with zoos due to the numerous exotic ruminant species that this virus can infect. BVDV occurs as both a non-cytopathic and a cytopathic strain both of which are capable of infecting exotic ruminants. The cytopathic strain causes mucosal disease (MD) and death. Infection with the non-cytopathic strain may produce persistently infected (PI) animals. PI individuals may show vague clinical signs, including abortion. Management of BVDV in zoos should focus on identification of PI individuals and prevention of infection of other animals of the collection. Variability makes serological testing as the sole method of screening for BVDV infection undesirable in exotic ruminants. Combination testing provides a definitive answer, especially in sensitive wildlife. Use of a combination of antigen-capture ELISA (ACE) with haired skin, Real Time-PCR (RT-PCR) on whole blood, and antibody detection via serum neutralization has the greatest potential to identify PI animals. An animal that is positive on both ACE and RT-PCR, but is negative on serology should be considered highly suspicious of being a PI, and should be isolated and undergo repeat testing 4–6 weeks later to confirm positive status. This testing methodology also allows screening of pregnant and newborn animals. Isolation or culling may need to be considered in animals determined to be positive via combination testing. These decisions should only be made after careful consideration and evaluation, especially with endangered species. PMID:26779151

Vector-borne transmission of Trypanosoma cruzi among captive Neotropical primates in a Brazilian zoo.

Neotropical primates are important sylvatic hosts of Trypanosoma cruzi, the etiological agent of Chagas disease. Infection is often subclinical, but severe disease has been described in both free-ranging and captive primates. Panstrongylus megistus, a major T. cruzi vector, was found infesting a small-primate unit at Brasília zoo (ZooB), Brazil. ZooB lies close to a gallery-forest patch where T. cruzi circulates naturally. Here, we combine parasitological and molecular methods to investigate a focus of T. cruzi infection involving triatomine bugs and Neotropical primates at a zoo located in the Brazilian Savannah. We assessed T. cruzi infection in vectors using optical microscopy (n = 34) and nested PCR (n = 50). We used quantitative PCR (qPCR) to examine blood samples from 26 primates and necropsy samples from two primates that died during the study. We determined parasite lineages in five vectors and two primates by comparing glucose-6-phosphate isomerase (G6pi) gene sequences. Trypanosoma cruzi was found in 44 vectors and 17 primates (six genera and eight species); one Mico chrysoleucus and one Saguinus niger had high parasitaemias. Trypanosoma cruzi DNA was detected in three primates born to qPCR-negative mothers at ZooB and in the two dead specimens. One Callithrix geoffroyi became qPCR-positive over a two-year follow-up. All G6pi sequences matched T. cruzi lineage TcI. Our findings strongly suggest vector-borne T. cruzi transmission within a small-primate unit at ZooB - with vectors, and perhaps also parasites, presumably coming from nearby gallery forest. Periodic checks for vectors and parasites would help eliminate T. cruzi transmission foci in captive-animal facilities. This should be of special importance for captive-breeding programs involving endangered mammals, and would reduce the risk of accidental T. cruzi transmission to keepers and veterinarians.

Nutritional status for six captive canid species (n=34) and four captive ursid species (n=18) were analyzed. The species analyzed included: African wild dog (Lycaon pictus), arctic fox (Alopex lagopus), gray wolf (Canis lupus), maned wolf (Chrysocyon brachyurus), Mexican wolf (Canis lupus baleiyi), red wolf (Canis rufus), brown bear (Ursus arctos), polar bear (Ursus maritimus), spectacled bear (Tremarctos ornatus), and sun bear (Ursus malayanus). Diet information was collected for these animals from each participating zoo (Brookfield Zoo, Fort Worth Zoo, Lincoln Park Zoological Gardens, and North Carolina Zoological Park). The nutritional composition of the diet for each species at each institution met probable dietary requirements. Blood samples were collected from each animal and analyzed for vitamin D metabolites 25(OH)D and 1,25(OH)(2)D, vitamin A (retinol, retinyl stearate, retinyl palmitate), vitamin E (alpha-tocopherol and gamma-tocopherol) and selected carotenoids. Family differences were found for 25(OH)D, retinol, retinyl stearate, retinyl palmitate and gamma-tocopherol. Species differences were found for all detectable measurements. Carotenoids were not detected in any species. The large number of animals contributing to these data, provides a substantial base for comparing the nutritional status of healthy animals and the differences among them.

How Abnormal Is the Behaviour of Captive, Zoo-Living Chimpanzees?

2011-01-01

Background Many captive chimpanzees (Pan troglodytes) show a variety of serious behavioural abnormalities, some of which have been considered as possible signs of compromised mental health. The provision of environmental enrichments aimed at reducing the performance of abnormal behaviours is increasing the norm, with the housing of individuals in (semi-)natural social groups thought to be the most successful of these. Only a few quantitative studies of abnormal behaviour have been conducted, however, particularly for the captive population held in zoological collections. Consequently, a clear picture of the level of abnormal behaviour in zoo-living chimpanzees is lacking. Methods We present preliminary findings from a detailed observational study of the behaviour of 40 socially-housed zoo-living chimpanzees from six collections in the United States of America and the United Kingdom. We determined the prevalence, diversity, frequency, and duration of abnormal behaviour from 1200 hours of continuous behavioural data collected by focal animal sampling. Results, Conclusion and Significance Our overall finding was that abnormal behaviour was present in all sampled individuals across six independent groups of zoo-living chimpanzees, despite the differences between these groups in size, composition, housing, etc. We found substantial variation between individuals in the frequency and duration of abnormal behaviour, but all individuals engaged in at least some abnormal behaviour and variation across individuals could not be explained by sex, age, rearing history or background (defined as prior housing conditions). Our data support a conclusion that, while most behaviour of zoo-living chimpanzees is ‘normal’ in that it is typical of their wild counterparts, abnormal behaviour is endemic in this population despite enrichment efforts. We suggest there is an urgent need to understand how the chimpanzee mind copes with captivity, an issue with both scientific and welfare

A potentially fatal mix of herpes in zoos.

Pathogens often have a limited host range, but some can opportunistically jump to new species. Anthropogenic activities that mix reservoir species with novel, hence susceptible, species can provide opportunities for pathogens to spread beyond their normal host range. Furthermore, rapid evolution can produce new pathogens by mechanisms such as genetic recombination. Zoos unintentionally provide pathogens with a high diversity of species from different continents and habitats assembled within a confined space. Institutions alert to the problem of pathogen spread to unexpected hosts can monitor the emergence of pathogens and take preventative measures. However, asymptomatic infections can result in the causative pathogens remaining undetected in their reservoir host. Furthermore, pathogen spread to unexpected hosts may remain undiagnosed if the outcome of infection is limited, as in the case of compromised fertility, or if more severe outcomes are restricted to less charismatic species that prompt only limited investigation. We illustrate this problem here with a recombinant zebra herpesvirus infecting charismatic species including zoo polar bears over at least four years. The virus may cause fatal encephalitis and infects at least five mammalian orders, apparently without requiring direct contact with infected animals. Copyright © 2012 Elsevier Ltd.

To appreciate the genetic diversity and zoonotic implications of Enterocytozoon bieneusi in nonhuman primates (NHPs) in zoos, we genotyped E. bieneusi in captive NHPs in seven zoos located at six major cities in China, using ribosomal internal transcribed spacer (ITS)-based PCR and sequence analyses. A total of 496 fecal specimens from 36 NHP species under nine families were analyzed and E. bieneusi was detected in 148 (29.8%) specimens of 25 NHP species from six families, including Cercopithecidae (28.7%), Cebidae (38.0%), Aotidae (75.0%), Lemuridae (26.0%), Hylobatidae (50.0%) and Hominidae (16.2%) (P = 0.0605). The infection rates were 29.0%, 15.2%, 18.2%, 37.3%, 29.2%, 37.7% and 44.8% in Shijiazhuang Zoo, Wuhan Zoo, Taiyuan Zoo, Changsha Wild Animal Zoo, Beijing Zoo, Shanghai Zoo and Shanghai Wild Animal Park, respectively (P = 0.0146). A total of 25 ITS genotypes were found: 14 known (D, O, EbpC, EbpA, Type IV, Henan-IV, BEB6, BEB4, Peru8, PigEBITS5, EbpD, CM1, CM4 and CS-1) and 11 new (CM8 to CM18). Genotype D was the most prevalent one (40/148), followed by CM4 (20/148), CM1 (15/148), O (13/148), CM16 (13/148), EbpC (11/148). Of them, genotypes D, EbpC, CM4 and O were widely distributed in NHPs (seen in 9 to 12 species) whereas genotypes CM1 and CM16 were restricted to one to three NHP species. In phylogenetic analysis, 20 genotypes (121/148, 81.8%), excluding genotypes BEB4, BEB6, CM9, CM4 and CM18, belonged to group 1 with zoonotic potential. New genotype CM9 clustered in group 2 with BEB4 and BEB6. The remaining two genotypes CM4 and CM18 formed new cluster (group 9) in between two other genotypic clusters found in primates. The findings of high diversity in E. bieneusi genotypes and their zoonotic potentiality concluded the importance of captive NHPs as reservoir hosts for human microsporidiosis. PMID:25705879

2016-01-01

Improving the welfare of nonhuman animals in captivity and maintaining behavioral competence for future conservation purposes is of the highest priority for zoos. The behavior of an aggressive male drill (Mandrillus leucophaeus poensis) was assessed in Barcelona Zoo. The 2-year study presented in this article examined the effects of introducing changes in the exhibit of the drill to improve his welfare by analyzing scan behaviors. First, a partial visual barrier was applied and proved to be insufficient to decrease the long-term stress indicators assessed. Next, a feeding enrichment program was implemented. The results supported the hypothesis that feeding and explorative activities would increase, whereas apathetic and stereotypic behaviors would decrease. However, visitor-directed aggression did not vary, indicating that more profound structural modifications were needed to reduce the negative impact of the agonistic interactions between the drill and the public. The study emphasized the usefulness of environmental enrichment evaluations in assessing captive animal welfare.

Zoo visitor perceptions, attitudes, and conservation intent after viewing African elephants at the San Diego Zoo Safari Park.

Elephants in the wild face several conservation issues. With the rebranding of zoos as conservation and education pioneers, they have the ability to both educate and inspire guests to action. The purpose of this research was to analyze visitor perceptions and attitudes toward elephant conservation and outcomes post-exhibit visit. A one-page survey was randomly administered to assess perceptions of elephant behavior, attitudes about elephant conservation, and intended conservation-related outcomes from September 2013 to January 2014. Principle component analysis identified three major components: concern for elephants in zoos, importance of elephants in the wild, and modification of nature. Visitors who scored highly on conservation intent were those with positive attitudes towards elephants in the wild and negative attitudes regarding the modification of nature. The greatest changes in conservation intent were a result of a self-reported up-close encounter and the ability to witness active behaviors. Providing guests with the opportunity to witness or experience such occurrences may aid in a more successful delivery of the zoo's conservation message. Further research into guest emotions and affective states in relation to viewing elephants in a zoological institution would provide greater insight into improving the guest experience and helping zoos meet their conservation mission.

We conducted the first horizon scan for zoos and aquariums to identify the 10 most important emerging issues for species conservation. This involved input from more than 100 experts from both the wider conservation community and the world zoo and aquarium community. Some of the issues are globally important: diseases, zoonoses, and biosecurity issues; new (communication) technologies; global water shortage and food insecurity; developing economies and markets for wildlife consumption; changes in wildlife population dynamics; and political instability and conflicts. Other issues are more specific to zoos and aquariums: need for extractive reserves; space shortage in zoos and aquariums; need for metapopulation management; and demand for caring of more species in zoos and aquariums. We also identified some broad approaches to these issues. Addressing the emerging issues identified in our horizon scan will further increase the contribution of the world zoo and aquarium community to global biodiversity conservation. © 2014 Wiley Periodicals, Inc.

Managing waste from confined animal feeding operations in the United States: the need for sanitary reform.

PubMed

Graham, Jay P; Nachman, Keeve E

2010-12-01

Confined food-animal operations in the United States produce more than 40 times the amount of waste than human biosolids generated from US wastewater treatment plants. Unlike biosolids, which must meet regulatory standards for pathogen levels, vector attraction reduction and metal content, no treatment is required of waste from animal agriculture. This omission is of concern based on dramatic changes in livestock production over the past 50 years, which have resulted in large increases in animal waste and a high degree of geographic concentration of waste associated with the regional growth of industrial food-animal production. Regulatory measures have not kept pace with these changes. The purpose of this paper is to: 1) review trends that affect food-animal waste production in the United States, 2) assess risks associated with food-animal wastes, 3) contrast food-animal waste management practices to management practices for biosolids and 4) make recommendations based on existing and potential policy options to improve management of food-animal waste.

From Animal Waste to Energy; A Study of Methane Gas converted to Energy.

NASA Astrophysics Data System (ADS)

Weiss, S.

2016-12-01

Does animal waste produce enough harvestable energy to power a household, and if so, what animal's waste can produce the most methane that is usable. What can we power using this methane and how can we power these appliances within an average household using the produced methane from animal waste. The waste product from animals is readily available all over the world, including third world countries. Using animal waste to produce green energy would allow low cost energy sources and give independence from fossil fuels. But which animal produces the most methane and how hard is it to harvest? Before starting this experiment I knew that some cow farms in the northern part of the Central California basin were using some of the methane from the waste to power their machinery as a safer, cheaper and greener source through the harnessed methane gas in a digester. The fermentation process would occur in the digester producing methane gasses as a side product. Methane that is collected can later be burned for energy. I have done a lot of research on this experiment and found that many different farm and ranch animals produce methane, but it was unclear which produced the most. I decided to focus my study on the waste from cows, horses, pig and dogs to try to find the most efficient and strongest source of methane from animal waste. I produced an affordable methane digester from plastic containers with a valve to attach a hose. By putting in the waste product and letting it ferment with water, I was able to produce and capture methane, then measure the amount with a Gaslab meter. By showing that it is possible to create energy with this simple digester, it could reduce pollution and make green energy easily available to communities all over the world. Eventually this could result into our sewer systems converting waste to energy, producing an energy source right in your home.

Problems with parasitic infections and their interspecies transmissions are common in zoological gardens and could pose serious health damage to captive animals. This study presents results of eight-year monitoring of intestinal parasites in animals from Zoo Ljubljana, Slovenia. A total of 741 faecal samples from 40 animal species were collected two to four times per year and examined microscopically. Intestinal parasites were detected in 45% of samples, with detection of helminths (Cestoda, Nematoda - Ascaridida, Enoplida, Strongylida, Oxyurida, Rhabditida and Trichurida) and protists (Apicomplexa and Ciliophora) in 25% and 13% of samples, respectively; mixed infection was found in 7% of samples. The mostly infected were ungulates (61%), followed by reptiles (44%), ratites (29%), primates (22%) and carnivores (7%). During the observation period, the number of infected animal species increased from 8 to 25. This is the first long-term monitoring study of intestinal parasites in zoo animals from Slovenia. Routine monitoring of parasitic infection and regular deworming and hygienic measures are necessary to prevent gastrointestinal infections in captive animals.

Methods of contraception are necessary for management of zoo felids; however, the most commonly used contraceptive (melengestrol acetate implant) is associated with serious adverse reactions with long-term use. Porcine zona pellucida (pZP) vaccines are promising as contraceptives, but their safety in zoo felids has not been tested. pZP vaccine was administered to 27 female felids representing 10 species, including African lion (Panthera leo), Asian leopard (P. pardus), jaguar (P. onca), tiger (P. tigris), snow leopard (P. uncia), cougar (Felis concolor), Siberian lynx (F. lynx), Canada lynx (F. canadensis), serval (F. serval), and bobcat (F. rufus), in 15 facilities. Over 6 wk, each animal received three i.m. injections of 65 microg pZP with Freund's complete adjuvant (FCA), Freund's incomplete adjuvant, or carbopol as the adjuvant. Behavioral signs of estrus were seen in 14 of the vaccinated felids. An unacceptably high incidence of adverse reactions was seen including injection site swelling, lameness, limb swelling, or abscessation (or all) in five felids after injection with FCA as the initial adjuvant. Adverse behavioral signs, including increased irritability and aggression, were seen in four felids. Six of the felids were assayed for antibodies against pZP during the 12 mo after vaccination; all showed antibody production. Antibody levels appeared to peak 1-4 mo after vaccination began, although elevated antibody levels persisted in two animals for > 12 mo after the first injection. All vaccinated felids were ovariohysterectomized 3-13 mo after vaccination. Folliculogenesis was present in all treated animals, and there was no histopathologic evidence of inflammatory damage to ovaries. Contraceptive efficacy was not specifically evaluated in this study; however, two of the three felids housed with an intact male became pregnant during the study, one of which gave birth to healthy cubs.

Ocular oxyspirurosis of primates in zoos: intermediate host, worm morphology, and probable origin of the infection in the Moscow zoo.

PubMed

Ivanova, E; Spiridonov, S; Bain, O

2007-12-01

Over the last century, only two cases of ocular oxyspirurosis were recorded in primates, both in zoos, and two species were described: in Berlin, Germany, Oxyspirura (O.) conjunctivalis from the lemurid Microcebus murinus, later also found in the lorisid Loris gracilis; in Jacksonville, Florida, O. (O.) youngi from the cercopithecid monkey Erythrocebus patas. In the present case from the Moscow zoo, oxyspirurosis was recorded in several species of Old World lemuriforms and lorisiforms, and some South American monkeys. i) The intermediate host was discovered to be a cockroach, as for O. (O.) mansoni, a parasite of poultry. The complete sequence identity between ITS-1 rDNA from adult nematodes of the primate and that of the larval worms from the vector, Nauphoete cinerea, confirmed their conspecificity. ii) Parasites from Moscow zoo recovered from Nycticebus c. coucang were compared morphologically to those from other zoos. The length and shape of the gubernaculum, used previously as a distinct character, were found to be variable. However, the vulvar bosses arrangement, the distal extremity of left spicule and the position of papillae of the first postcloacal pair showed that the worms in the different samples were not exactly identical and that each set seemed characteristic of a particular zoo. iii) The presence of longitudinal cuticular crests in the infective stage as well as in adult worms was recorded. Together with several other morphological and biological characters (long tail and oesophagus, cockroach vector), this confirmed that Oxyspirura is not closely related to Thelazia, another ocular parasite genus. iv) The disease in the Moscow zoo is thought to have started with Nycticebus pygmaeus imported fromVietnam, thus the suggestion was that Asiatic lorisids were at the origin of the Moscow set of cases. The natural host(s) for the Berlin and Jacksonville cases remain unknown but they are unlikely to be the species found infected in zoos. Consequently the

Serum concentrations of several nutrients were measured in 12 captive wild felid species including caracal (Felis caracal), cheetah (Acinonyx jubatus), cougar (Felis concolor), fishing cat (Felis viverrinus), leopard (Panthera pardus), lion (Panthera leo), ocelot (Felis pardalis), pallas cat (Felis manul), sand cat (Felis margarita), serval (Felis serval), snow leopard (Panthera uncia) and tiger (Panthera tigris). Diet information was collected for these animals from each participating zoo (Brookfield Zoo, Fort Worth Zoo, Lincoln Park Zoological Gardens and North Carolina Zoological Park). The nutritional composition of the diets at each institution met the probable dietary requirements for each species except for the pallas cat. Blood samples were collected from each animal (n = 69) and analyzed for lipids (total cholesterol, triacylglycerides, HDL cholesterol and LDL cholesterol), vitamin D metabolites [25-hydroxycholecalciferol (25(OH)D) and 1,25-dihydroxycholecalciferol (1,25(OH)(2)D)], vitamin A (retinol, retinyl stearate and retinyl palmitate), vitamin E (alpha- and gamma-tocopherol) and selected carotenoids. Species differences were found for all except triacylglycerides and 1,25(OH)(2)D. Genus differences were found for retinol, retinyl palmitate, retinyl stearate, gamma-tocopherol and beta-carotene. Circulating nutrient concentrations for many of the species in this study have not been reported previously and most have not been compared with the animals' dietary intakes. The large number of animals analyzed provides a substantial base for comparing the serum nutrient concentrations of healthy animals, for both wild and captive exotic species.

Two fatal tiger attacks in zoos.

PubMed

Tantius, Britta; Wittschieber, Daniel; Schmidt, Sven; Rothschild, Markus A; Banaschak, Sibylle

2016-01-01

Two captive tiger attacks are presented that took place in Cologne and Münster zoos. Both attacks occurred when the handlers, intent on cleaning the enclosures, entered whilst the tigers accidently retained access to the location, and thus defended their territory against the perceived intruders. Both victims suffered fatal neck injuries from the bites. At Münster, colleagues managed to lure the tiger away from its victim to enable treatment, whilst the Cologne zoo tiger had to be shot in order to allow access to be gained. Whilst it was judged that human error led to the deaths of the experienced zookeepers, the investigation in Münster was closed as no third party was found to be at fault, whereas the Cologne zoo director was initially charged with being negligent. These charges were subsequently dismissed as safety regulations were found to be up to date.

Cows outnumbered bulls 4 to 1 (Loxodonta) and 3 to 1 (Elephas). Groups contained 7 or fewer: mean, 4.28 (sigma = 5.73). One fifth of elephants lived alone or with one conspecific. Forty-six elephants (5.5%) had no conspecific. Many zoos ignore minimum group sizes of regional zoo association guidelines. The American Zoo and Aquarium Association recommends that breeding facilities keep herds of 6 to 12 elephants. The British and Irish Association of Zoos and Aquariums recommends keeping together at least 4 cows over 2 years old. Over 69% Asian and 80% African cow groups-including those under 2 years-consisted of fewer than 4 individuals. Recently, Europe and North America have made progress with some zoos no longer keeping elephants and with others investing in improved facilities and forming larger herds. The welfare of individual elephants should outweigh all other considerations; zoos should urgently seek to integrate small groups into larger herds.

Usually cited in reference to the potential reach of zoo education, one of the popular figures for global zoo visitation is that 600 million people visit zoos annually. However, this number needs clarification on two fronts. First, there are many zoo visitors who are not included in the calculation because they visited a zoo that was not included in the count. Second, it does not take into consideration the people visit either the same or different zoos more than once annually. Using data collected from several sources, including zoo visitors themselves, this article focuses on one country--Australia--that contributes 15.6 million to the visitation total, and contends that the correct number of unique annual zoo visitors to Australian zoos is likely to be between 8 and 10 million. However, rather than suggesting an overemphasis on the potential of zoos for educating visitors, having regular repeat visitors represents a distinct advantage for zoos, allowing for progressive education opportunities. © 2012 Wiley Periodicals, Inc.

Understanding factors that influence reproduction and offspring survival in zoo populations is critical for management of threatened and endangered species. Examination of long-term data (1989-2011) compiled from the Association of Zoos and Aquarium's zoo-managed tiger breeding program provides the basis for a more thorough understanding of reproduction and scientifically based decisions for effective population management in this endangered felid. Biological and management-related factors that could influence tiger breeding success and cub survival were evaluated using logistic mixed models. Breeding success improved with female age until approximately age five, then declined thereafter. Experienced female breeders had greater breeding success than inexperienced females. Litter size was most predictive of cub survival, with average-sized litters (3-4 cubs) experiencing the highest proportional survival. Management-related factors, such as whether the breeding institution had a recent tiger litter and whether both animals were already located at the same institution, also influenced breeding success and cub survival. These results highlight the importance of institutional husbandry experience and the need to retain knowledge through staff turnovers to achieve optimal reproductive success. Using fecal estrogen data, frequency of ovarian cyclicity and mean cycle length did not differ by female age or parity; thus, lack of cyclicity and/or increased cycle duration are not likely explanations for declining breeding success with age. These results provide valuable reproductive information that should improve scientific management of zoo-based tiger populations. Copyright © 2013 Elsevier B.V. All rights reserved.

A survey conducted by the World Association of Zoos and Aquariums, in collaboration with national and regional zoo and aquarium associations, showed that annually more than 700 million people visit zoos and aquariums worldwide and are thus potentially exposed to environmental education. Furthermore, the world zoo and aquarium community reportedly spends about US$ 350 million on wildlife conservation each year. Therefore, the world zoo and aquarium community has the potential to play an important role in both environmental education and wildlife conservation. Systematic reviews are encouraged to provide further evidence for the effectiveness of zoos and aquariums as centers of education and conservation. © 2010 Wiley Periodicals, Inc.

Antibiotic resistance in avian pathogenic Escherichia coli (APEC) is a common problem in the Indonesian poultry industry. Zoo birds have been postulated as sentinels, reservoirs, and potential spreaders of antibiotic resistance, although much is still unknown about the strains of zoo birds. Disinfection can reduce the infection burden. However, little is known about the presence of resistance against these products. Sixty one APEC strains were isolated from Indonesian zoo birds. The resistance to different classes of antibiotics as well as the minimum inhibitory concentrations (MIC) and minimum bactericidal concentrations (MBC) of five disinfectants most often used in the poultry industry was determined. Resistance to tetracycline (42.6%), sulfonamides (24.5%), ampicillin (22.9%), gentamicin (19.6), nalidixic acid (18.03%) and streptomycin (16.3%) was high, but resistance to other tested antibiotics was low and none of the isolates were resistant to extended spectrum beta-lactamase (ESBL) producers. Sixteen strains (26.2%) were found positive for multi drug resistance. The MIC of the disinfectants for the APEC strains showed normal distribution, indicating that there was no acquired resistance. MBCs were similar to MICs using the broth dilution method, showing the bactericidal effect of the disinfectants. Phenotypic resistance to commonly used disinfectants could not be found, indicating that the current use of disinfectants in the zoo and aviaries did not select for resistance. Significantly high resistance rates against commonly used antibiotics in Indonesian zoos is worrisome and indicates that widespread use of antibiotics could have negative implications for animal health and the environment. Proper use of antibiotics and surveillance programs to monitor antimicrobial resistance in pathogenic bacteria are warranted.

Fatal injuries caused by attacks by large wild cats are extremely rare in forensic medical practice in Europe. There are very few cases described in the forensic medical literature concerning incidents in zoos similar to the tiger attack on a 58-year-old male zoo employee that we present here. While preparing a runway for tigers, the man was attacked by a male Sumatran tiger. Another zoo employee was an eyewitness to the accident; in his testimony he described the sequence of events in detail. The autopsy showed the injuries typical of a tiger attack: traces of claws and canine teeth indicating that the victim of the attack was knocked down from behind, along with deep and extensive fatal wounds to the neck. The injuries were inflicted by means of a compound mechanism: tissues were penetrated by the animal's canines, crushed with great force (transfixing injury), and violently distended. The skin revealed four characteristic deep wounds caused by canines as well as bite marks resulting from the action of six incisors. The neck area revealed extensive damage, including torn muscles, the esophagus and trachea, large blood vessels of the neck, and fractures of vertebrae C2 and C5 with internal channels resulting directly from penetration by the animal's canines. The mechanism of distension, as a result of the animal jerking its head after biting the victim in the neck, produced a complete tear of the spine and the vertebral arteries, as well as an intramural rupture of the carotid arteries which has never been described before. In the interests of a detailed assessment of bone damage, the cervical spine was macerated. The applied autopsy techniques and detailed analysis of injuries enabled us to demonstrate the compound mechanism that inflicted them, combining penetration of tissues by the canines, crushing, and distension.

The hepatitis E virus (HEV) has been described in humans and various animal species in different regions of the world. However, the knowledge on natural HEV infection in non-human primates and the corresponding risk of zoonotic transmission is scarce. To determine whether primates in captivity are affected by HEV infection, we investigated 259 individual sera of clinically healthy non-human primates of 14 species from nine German zoos. Using a commercial double-antigen-sandwich ELISA and a commercial IgG ELISA, 10 animals (3·9%) reacted positive in at least one assay. Three ape species and one Old World monkey species were among the seropositive animals: bonobo (Pan paniscus), gorilla (Gorilla gorilla gorilla), lar gibbon (Hylobates lar) and drill (Mandrillus leucophaeus). Testing for anti-HEV-IgM antibodies by commercial ELISA and for viral RNA by reverse-transcription real-time polymerase chain reaction resulted in negative results for all animals indicating the absence of acute HEV infections. In the past, no clinical signs of hepatitis were recorded for the seropositive animals. The results suggest that non-human primates in zoos can get naturally and subclinically infected with HEV or related hepeviruses. Future studies should evaluate potential sources and transmission routes of these infections and their impact on human health.

General anesthesia poses risks for larger zoo species, like cardiorespiratory depression, myopathy, and hyperthermia. In ruminants, ruminal bloat and regurgitation of rumen contents with potential aspiration pneumonia are added risks. Thus, the use of sedation to perform minor procedures is justified in zoo animals. A combination of detomidine and butorphanol has been routinely used in domestic animals. This drug combination, administered by remote intramuscular injection, can also be applied for standing sedation in a range of zoo animals, allowing a number of minor procedures. The combination was successfully administered in five species of nondomesticated equids (Przewalski horse [ Equus ferus przewalskii; n = 1], onager [ Equus hemionus onager; n = 4], kiang [ Equus kiang ; n = 3], Grevy's zebra [ Equus grevyi ; n = 4], and Somali wild ass [ Equus africanus somaliensis; n = 7]), with a mean dose range of 0.10-0.17 mg/kg detomidine and 0.07-0.13 mg/kg butorphanol; the white ( Ceratotherium simum simum; n = 12) and greater one-horned rhinoceros ( Rhinoceros unicornis ; n = 4), with a mean dose of 0.015 mg/kg of both detomidine and butorphanol; and Asiatic elephant bulls ( Elephas maximus ; n = 2), with a mean dose of 0.018 mg/kg of both detomidine and butorphanol. In addition, the combination was successfully used for standing sedation in six species of artiodactylids: giraffe ( Giraffa camelopardalis reticulata; n = 3), western bongo ( Tragelaphus eurycerus eurycerus; n = 2), wisent ( Bison bonasus ; n = 5), yak ( Bos grunniens ; n = 1), water buffalo ( Bubalus bubalis ; n = 4) and Bactrian camel ( Camelus bactrianus ; n = 5). The mean dose range for artiodactylid species except bongo was 0.04-0.06 mg/kg detomidine and 0.03-0.06 mg/kg butorphanol. The dose in bongo, 0.15-0.20 mg/kg detomidine and 0.13-0.15 mg/kg butorphanol, was considerably higher. Times to first effect, approach, and recovery after antidote were short. The use of detomidine and butorphanol has

Today, accredited zoos are not just places for entertainment, they are actively involved in research for conservation and health. During recent decades in which the challenges for biodiversity conservation and public health have escalated, zoos have made significant changes to address these difficulties. Zoos increasingly have four key areas of focus: education, recreation, conservation, and research. These key areas are important in addressing an interrelated global conservation ( i.e. habitat and wildlife loss) and public health crisis. Zoo and public health professionals working together within a One Health framework represent a powerful alliance to address current and future conservation and public health problems around the world. For researchers, practitioners, and students, the collaboration between zoos and public health institutions offers the opportunity to both teach and operationalize this transdisciplinary approach. Using examples from our programs, we give a template for moving forward with collaborative initiatives and sustainable solutions involving partners in both zoos and public health institutions. We provide examples of cooperative programs and suggest a model for consideration in the development of further activities in this area.

The educational claims of zoos: where do we go from here?

PubMed

Moss, Andrew; Esson, Maggie

2013-01-01

Zoos exude a certain self-confidence regarding their roles as education providers. Indeed, the education outputs of zoos are, at face value, pretty impressive, with most investing in learning opportunities for leisure visitors, education groups and in some cases, as part of their in situ programs. However, these outputs are not necessarily reliable indicators of the educational achievements of zoos. Quantity does not necessarily equate to quality, just as outputs do not necessarily lead to outcomes. Zoo-accreditation organizations such as the AZA and EAZA offer us clear insight into the strategic vision underpinning the education goals for zoo visitors; a heightened appreciation of the value of biodiversity and a connectedness with the natural world. Unsurprisingly, most zoos have educational goals that ally neatly with the vision of their respective accreditation body. Consequently, we are left with fairly narrow, top-down educational goals. This does not necessarily sit well with what we know about the unpredictability of "free choice" learning in environments such as zoos and aquariums, or what is known about public science communication. Research that seeks to explore the impacts of zoo visits often focuses on evaluating performance based on educational goals and the findings are used as a means of providing evidence of institutional achievement. However, any visitor outcome that falls outside of this narrow range could well be missed by the research. In this article, we propose that research that takes unpredictable and unexpected outcomes into account is necessary and overdue. © 2012 Wiley Periodicals, Inc.

Animal and industrial waste anaerobic digestion: USA status report

Lusk, P.D.

1996-01-01

Pollutants from unmanaged animal and bio-based industrial wastes can degrade the environment, and methane emitted from decomposing wastes may contribute to global climate change. One waste management system prevents pollution and converts a disposal problem into a new profit center. Case studies of operating systems indicate that the anaerobic digestion of animal and industrial wastes is a commercially available bioconversion technology with considerable potential for providing profitable coproducts, including a cost-effective renewable fuel. Growth and concentration of the livestock industry create opportunities to properly dispose of the large quantities of manures generated at dairy, swine, and poultry farms. Beyond themore » farm, extension of the anaerobic digestion process to recover methane has considerable potential for certain classified industries - with a waste stream characterization similar to livestock manures. More than 35 example industries have been identified, and include processors of chemicals, fiber, food, meat, milk, and pharmaceuticals. Some of these industries already recover methane for energy. This status report examines some current opportunities for recovering methane from the anaerobic digestion of animal and industrial wastes in the US. Case studies of operating digesters, including project and maintenance histories, and the operator`s {open_quotes}lessons learned,{close_quotes} are included as a reality check. Factors necessary for successful projects, as well as a list of reasons explaining why some anaerobic digestion projects fail, are provided. The role of management is key; not only must digesters be well engineered and built with high-quality components, they must also be sited at facilities willing to incorporate the uncertainties of a new technology. Anaerobic digestion can provide monetary benefits and mitigate possible pollution problems, thereby sustaining development while maintaining environmental quality.« less

Metastrongyloid induced pneumonia has been described sporadically in the red panda (Ailurus fulgens). Early descriptions in pandas recently imported to the USA from China involved parasites morphologically similar to Angiostrongylus spp. and Crenosomatidae. More recently, four cases of severe verminous pneumonia associated with Angiostrongylus vasorum have been reported from European zoos. A coprological survey of the red panda population within European zoos was conducted in 2008. Faecal samples from 115 pandas originating from 54 zoos were collected on 3 consecutive days. Using Baermann technique, 40 animals (35%) from 20 zoos (37%) were found to shed metastrongyloid first stage larvae (L(1)). Based on their morphology and size, the L(1) observed could be divided into three morphologically distinct types: (1) a Crenosoma sp. type (n=5, overall prevalence: 4.3%), (2) an A. vasorum type (n=3, 2.6%), and (3) an unidentified metastrongyloid species, similar to, but morphologically distinct from A. vasorum (n=32, 27.8%). Further confirmation of species identification was provided by PCR amplification and sequencing of the 18S rRNA gene, which confirmed three different species. The novel Crenosoma species was most genetically analogous to Crenosoma mephitidis and the unidentified metastrongyloid species was most similar to Stenurus minor and Torynurus convulutus. Routine and quarantine health care of red pandas in captivity should take account of the risk of Angiostrongylus and Crenosoma infection in endemic areas, but should also be cognisant of the widespread presence of an apparently less pathogenic species of lungworm. The identity of the two potentially novel species is subject to further work.

DISEASE RISK ANALYSIS--A TOOL FOR POLICY MAKING WHEN EVIDENCE IS LACKING: IMPORT OF RABIES-SUSCEPTIBLE ZOO MAMMALS AS A MODEL.

Hartley, Matt; Roberts, Helen

2015-09-01

Disease control management relies on the development of policy supported by an evidence base. The evidence base for disease in zoo animals is often absent or incomplete. Resources for disease research in these species are limited, and so in order to develop effective policies, novel approaches to extrapolating knowledge and dealing with uncertainty need to be developed. This article demonstrates how qualitative risk analysis techniques can be used to aid decision-making in circumstances in which there is a lack of specific evidence using the import of rabies-susceptible zoo mammals into the United Kingdom as a model.

Cultural Historical Activity Theory served as the analytical framework for the study of a professional development event for a zoo's education department, specifically designed to build understandings of "Affective Transformation," an element pertinent to the organization's strategic plan. Three key products—an Affective Transformation model, scaffolding schematic, and definition, "providing emotional experiences for visitors which increase caring for animals and nature that may lead to zoo-related nature-protective behaviors"—emerged as a result of ongoing deliberation among professional development community members over two days. Participants, including both management- and non-management-level staff, as well as an expert facilitator, contributed complementary expertise to the process. The discussions, therefore, crossed both vertical and horizontal layers of authority. Moreover, leadership was distributed across these levels in the development of these products. Members used pre-existing resources, as well as tools created in the course of the professional development event. Interactions among participants and resources were instrumental in Affective Transformation product development. Examination of one zoo's construction of understanding of affective goals, therefore, may offer insights to other organizations with similar aspirations.

This study was conducted at the Oklahoma City Zoo in fall 2010 and subjects were students' ages 14-18 who either participated in a formal conservation education class led by zoo educators or in a field trip in which they were engaged in free-choice learning. Two research questions were: 1) Does a trip to the zoo affect conservation attitudes and 2) does learning experience, free-choice or formal, affect conservation attitudes? A criterion group design was used and the instrument used to measure conservation attitudes was Tool 4 from the Visitor Evaluation Toolbox produced by the Association of Zoos and Aquariums MIRP study (Falk, J., Bronnenkant, K., Vernon, C., & Heimlich, J., 2009). Group one (N=110) engaged in a free-choice (field trip only) experience and group two (N=367) engaged in a formal conservation education class. The survey was administered retrospectively to both groups upon completion of their learning experience at the zoo. Statistical analysis was conducted using SPSS 17.0. A paired sample t-test showed the overall mean within both groups increased in a positive direction from 67.965 (retrospective) to 72.345 (present). With alpha set at .05 the two-tailed probability was <0.001, therefore confirming that the change in conservation attitudes was significant. An independent sample t-test of the change in scores between the groups produced p values of 0.792 and 0.773 and revealed that the change was not significant. Findings did illustrate that a trip to the zoo did positively and significantly affect conservation attitudes among teens and that the type of learning experience did not significantly affect change in conservation attitude scores.

Using a Field Trip Inventory to Determine If Listening to Elementary School Students' Conversations, While on a Zoo Field Trip, Enhances Preservice Teachers' Abilities to Plan Zoo Field Trips

2013-10-01

This study investigated whether listening to spontaneous conversations of elementary students and their teachers/chaperones, while they were visiting a zoo, affected preservice elementary teachers' conceptions about planning a field trip to the zoo. One hundred five preservice elementary teachers designed field trips prior to and after listening to students' conversations during a field trip to the zoo. In order to analyze the preservice teachers' field trip designs, we conducted a review of the literature on field trips to develop the field trip inventory (FTI). The FTI focussed on three major components of field trips: cognitive, procedural, and social. Cognitive components were subdivided into pre-visit, during-visit, and post-visit activities and problem-solving. Procedural components included information about the informal science education facility (the zoo) and the zoo staff and included advanced organizers. Social components on student groups, fun, control during the zoo visit, and control of student learning. The results of the investigation showed that (a) the dominant topic in conversations among elementary school groups at the zoo was management, (b) procedural components were mentioned least often, (c) preservice teachers described during-visit activities more often than any other characteristic central to field trip design, (d) seven of the nine characteristics listed in the FTI were noted more frequently in the preservice teachers' field trip designs after they listened to students' conversations at the zoo, and (e) preservice teachers thought that students were not learning and that planning was important.

Oosterman, Joukje M; Wijers, Marijn; Kessels, Roy P C

2013-01-01

The Zoo Map Test of the Behavioral Assessment of the Dysexecutive Syndrome battery is often applied to measure planning ability as part of executive function. Successful performance on this test is, however, dependent on various cognitive functions, and deficient Zoo Map performance does therefore not necessarily imply selectively disrupted planning abilities. To address this important issue, we examined whether planning is still the most important predictor of Zoo Map performance in a heterogeneous sample of neurologic and psychiatric outpatients (N = 71). In addition to the Zoo Map Test, the patients completed other neuropsychological tests of planning, inhibition, processing speed, and episodic memory. Planning was the strongest predictor of the total raw score and inappropriate places visited, and no additional contribution of other cognitive scores was found. One exception to this was the total time, which was associated with processing speed. Overall, our findings indicate that the Zoo Map Test is a valid indicator of planning ability in a heterogeneous patient sample.

Wild Origins: The Evolving Nature of Animal Behavior

Flores, Ifigenia

For billions of years, evolution has been the driving force behind the incredible range of biodiversity on our planet. Wild Origins is a concept plan for an exhibition at the National Zoo that uses case studies of animal behavior to explain the theory of evolution. Behaviors evolve, just as physical forms do. Understanding natural selection can help us interpret animal behavior and vice-versa. A living collection, digital media, interactives, fossils, and photographs will relay stories of social behavior, sex, navigation and migration, foraging, domestication, and relationships between different species. The informal learning opportunities visitors are offered at the zoo will create a connection with the exhibition's teaching points. Visitors will leave with an understanding and sense of wonder at the evolutionary view of life.

Impact of animal waste application on runoff water quality in field experimental plots.

PubMed

Hill, Dagne D; Owens, William E; Tchoounwou, Paul B

2005-08-01

Animal waste from dairy and poultry operations is an economical and commonly used fertilizer in the state of Louisiana. The application of animal waste to pasture lands not only is a source of fertilizer, but also allows for a convenient method of waste disposal. The disposal of animal wastes on land is a potential nonpoint source of water degradation. Water degradation and human health is a major concern when considering the disposal of large quantities of animal waste. The objective of this research was to determine the effect of animal waste application on biological (fecal coliform, Enterobacter spp. and Escherichia coli) and physical/chemical (temperature, pH, nitrate nitrogen, ammonia nitrogen, phosphate, copper, zinc, and sulfate) characteristics of runoff water in experimental plots. The effects of the application of animal waste have been evaluated by utilizing experimental plots and simulated rainfall events. Samples of runoff water were collected and analyzed for fecal coliforms. Fecal coliforms isolated from these samples were identified to the species level. Chemical analysis was performed following standard test protocols. An analysis of temperature, ammonia nitrogen, nitrate nitrogen, iron, copper, phosphate, potassium, sulfate, zinc and bacterial levels was performed following standard test protocols as presented in Standard Methods for the Examination of Water and Wastewater [1]. In the experimental plots, less time was required in the tilled broiler litter plots for the measured chemicals to decrease below the initial pre-treatment levels. A decrease of over 50% was noted between the first and second rainfall events for sulfate levels. This decrease was seen after only four simulated rainfall events in tilled broiler litter plots whereas broiler litter plots required eight simulated rainfall events to show this same type of reduction. A reverse trend was seen in the broiler litter plots and the tilled broiler plots for potassium. Bacteria numbers

The unsustainability of many animal programs managed by zoos and aquariums has brought renewed attention to unresolved questions about various management strategies. Solving the "sustainability crisis" for many species will require housing more adults and producing more offspring than there are existing spaces in accredited zoos and aquariums. Careful reproductive management is central to addressing this challenge, but opinions differ about which management strategies are best for an individual, for a species, for an institution, or for a country or region. The primary options for limiting the number of animals that would be surplus to the population are to prevent reproduction or to euthanize. However, there is much misunderstanding about methods for controlling reproduction, in particular about contraceptives and species differences in their effects. Careful weighing of all the options is called for. Lifetime Reproductive Planning may help increase breeding success through careful reproductive management but cannot eliminate production of surplus animals. Limiting reproduction does not address the problem of animals already in the population. Despite best efforts and planning, consistently hitting target numbers for a population may never be achieved. Increasing capacity provides a temporary patch when targets are exceeded, but is not a long-term solution, since each generation potentially produces even more individuals needing even more space. Welfare considerations should be included in discussions of management euthanasia and its alternatives. Such discussions will be most productive if based on full awareness of the advantages and disadvantages of all the options.

We present the detailed, visual morphologies of approximately 60,000 galaxies observed by the UKIRT Infrared Deep Sky Survey and then classified by participants in the Galaxy Zoo project. Our sample is composed entirely of nearby objects with redshifts of z ≤ 0.3, which enables us to robustly analyze their morphological characteristics including smoothness, bulge properties, spiral structure, and evidence of bars or rings. The determination of these features is made via a consensus-based analysis of the Galaxy Zoo project data in which inconsistent and outlying classifications are statistically down-weighted. We then compare these classifications of infrared morphology to the objects’ optical classifications in the Galaxy Zoo 2 release (Willett et al. 2013). It is already known that morphology is an effective tool for uncovering a galaxy’s dynamical past, and previous studies have shown significant correlations with physical characteristics such as stellar mass distribution and star formation history. We show that majority of the sample has agreement or expected differences between the optical and infrared classifications, but also present a preliminary analysis of a subsample of objects with striking discrepancies.

The disposal of food waste is a large environmental problem. In the United Kingdom (UK), approximately 15 million tonnes of food are wasted each year, mostly disposed of in landfill, via composting, or anaerobic digestion (AD). European Union (EU) guidelines state that food waste should preferentially be used as animal feed though for most food waste this practice is currently illegal, because of disease control concerns. Interest in the potential diversion of food waste for animal feed is however growing, with a number of East Asian states offering working examples of safe food waste recycling - based on tight regulation and rendering food waste safe through heat treatment. This study investigates the potential benefits of diverting food waste for pig feed in the UK. A hybrid, consequential life cycle assessment (LCA) was conducted to compare the environmental and health impacts of four technologies for food waste processing: two technologies of South Korean style-animal feed production (as a wet pig feed and a dry pig feed) were compared with two widespread UK disposal technologies: AD and composting. Results of 14 mid-point impact categories show that the processing of food waste as a wet pig feed and a dry pig feed have the best and second-best scores, respectively, for 13/14 and 12/14 environmental and health impacts. The low impact of food waste feed stems in large part from its substitution of conventional feed, the production of which has substantial environmental and health impacts. While the re-legalisation of the use of food waste as pig feed could offer environmental and public health benefits, this will require support from policy makers, the public, and the pig industry, as well as investment in separated food waste collection which currently occurs in only a minority of regions.

Measures of physiological stress in zoo animals can give important insights into how they are affected by aspects of their captive environment. We analysed the factors influencing variation in glucocorticoid metabolites in faeces (fGCs) from zoo meerkats as a proxy for blood cortisol concentration, high levels of which are associated with a stress response. Levels of fGCs in captive meerkats declined with increasing group size. In the wild, very small groups of meerkats are at a higher risk of predation, while in larger groups, there is increased competition for resources. Indeed, group sizes in captivity resemble those seen in unstable coalitions in the wild, which may represent a stressful condition and predispose meerkats to chronic stress, even in the absence of natural predators. Individuals in large enclosures showed lower levels of stress, but meerkat density had no effect on the stress measures. In contrast with data from wild meerkats, neither sex, age nor dominance status predicted stress levels, which may reflect less food stress owing to more equal access to resources in captivity versus wild. The median number of visitors at the enclosure was positively correlated with fGC concentrations on the following day, with variation in the visitor numbers having the opposite effect. Our results are consistent with the hypothesis that there is an optimum group size which minimizes physiological stress in meerkats, and that zoo meerkats at most risk of physiological stress are those kept in small groups and small enclosures and are exposed to consistently high numbers of visitors.

Aquatic animals are the most popular pets in the United States based on the number of owned pets. They are popular display animals and are increasingly used in research settings. Enrichment of captive animals is an important element of zoo and laboratory medicine. The importance of enrichment for aquatic animals has been slower in implementation. For a long time, there was debate over whether or not fish were able to experience pain or form long-term memories. As that debate has reduced and the consciousness of more aquatic animals is accepted, the need to discuss enrichment for these animals has increased. Copyright © 2015 Elsevier Inc.

Informal science institutions are a significant provider of science teacher professional development. As pressure continues to critically analyze the work of teachers and their effectiveness in the classroom, it is important to understand how informal science institutions contribute to effective change in teacher science content knowledge and pedagogy. This research study analyzed zoo and aquarium provided teacher professional development to respond to the research questions: How do zoos and aquaria determine and assess their goals for teacher professional development? How do these goals align with effective teacher change for science content knowledge and pedagogy? Theoretical frameworks for high quality teacher professional development, effective evaluation of teacher professional development, and learning in informal science settings guided the research. The sample for the study was AZA accredited zoos and aquariums providing teacher professional development (N=107). Data collection consisted of an online questionnaire, follow-up interviews, and content analysis of teacher professional development artifacts. Analysis revealed that by and large zoos and aquariums are lacking in their provision of science teacher professional development. Most professional development focuses on content or resources, neglecting pedagogy. Assessments mismatch the goals and rely heavily on self-report and satisfaction measures. The results demonstrate a marked difference between those zoos and aquariums that are larger in capacity versus those that are medium to small in size. This may be an area of research for the future, as well as analyzing the education resources produced by zoos and aquariums as these were emphasized heavily as a way they serve teachers.

Animal waste from dairy and poultry operations is an economical and commonly used fertilizer in the state of Louisiana. The application of animal waste to pasture lands not only is a source of fertilizer, but also allows for a convenient method of waste disposal. The disposal of animal wastes on land is a potential nonpoint source of water degradation. Water degradation and human health is a major concern when considering the disposal of large quantities of animal waste. The objective of this research was to determine the effect of animal waste application on biological (fecal coliform, Enterobacter spp. and Escherichia coli) and physical/chemical (temperature, pH, nitrate nitrogen, ammonia nitrogen, phosphate, copper, zinc, and sulfate) characteristics of runoff water in experimental plots. The effects of the application of animal waste have been evaluated by utilizing experimental plots and simulated rainfall events. Samples of runoff water were collected and analyzed for fecal coliforms. Fecal coliforms isolated from these samples were identified to the species level. Chemical analysis was performed following standard test protocols. An analysis of temperature, ammonia nitrogen, nitrate nitrogen, iron, copper, phosphate, potassium, sulfate, zinc and bacterial levels was performed following standard test protocols as presented in Standard Methods for the Examination of Water and Wastewater [1]. In the experimental plots, less time was required in the tilled broiler litter plots for the measured chemicals to decrease below the initial pre-treatment levels. A decrease of over 50% was noted between the first and second rainfall events for sulfate levels. This decrease was seen after only four simulated rainfall events in tilled broiler litter plots whereas broiler litter plots required eight simulated rainfall events to show this same type of reduction. A reverse trend was seen in the broiler litter plots and the tilled broiler plots for potassium. Bacteria numbers

Factors affecting yearly and monthly visits to Taipei Zoo

This study investigated factors affecting yearly and monthly numbers of visits to Taipei Zoo. Both linear and nonlinear regression models were used to estimate yearly visits. The results of both models showed that the "opening effect" and "animal star effect" had a significantly positive effect on yearly visits, while a SARS outbreak had a negative effect. The number of years had a significant influence on yearly visits. Results showed that the nonlinear model had better explanatory power and fitted the variations of visits better. Results of monthly model showed that monthly visits were significantly influenced by time fluctuations, weather conditions, and the animal star effect. Chinese New Year, summer vacation, numbers of holidays, and animal star exhibitions increased the number of monthly visits, while the number of days with temperatures at or below 15 °C, the number of days with temperatures at or above 30 °C, and the number of rainy days had significantly negative effects. Furthermore, the model of monthly visits showed that the animal star effect could last for over two quarters. The results of this study clarify the factors affecting visits to an outdoor recreation site and confirm the importance of meteorological factors to recreation use.

Energy Supply- Production of Fuel from Agricultural and Animal Waste

The Society for Energy and Environmental Research (SEER) was funded in March 2004 by the Department of Energy, under grant DE-FG-36-04GO14268, to produce a study, and oversee construction and implementation, for the thermo-chemical production of fuel from agricultural and animal waste. The grant focuses on the Changing World Technologies (CWT) of West Hempstead, NY, thermal conversion process (TCP), which converts animal residues and industrial food processing biproducts into fuels, and as an additional product, fertilizers. A commercial plant was designed and built by CWT, partially using grant funds, in Carthage, Missouri, to process animal residues from a nearby turkey processingmore » plant. The DOE sponsored program consisted of four tasks. These were: Task 1 Optimization of the CWT Plant in Carthage - This task focused on advancing and optimizing the process plant operated by CWT that converts organic waste to fuel and energy. Task 2 Characterize and Validate Fuels Produced by CWT - This task focused on testing of bio-derived hydrocarbon fuels from the Carthage plant in power generating equipment to determine the regulatory compliance of emissions and overall performance of the fuel. Task 3 Characterize Mixed Waste Streams - This task focused on studies performed at Princeton University to better characterize mixed waste incoming streams from animal and vegetable residues. Task 4 Fundamental Research in Waste Processing Technologies - This task focused on studies performed at the Massachusetts Institute of Technology (MIT) on the chemical reformation reaction of agricultural biomass compounds in a hydrothermal medium. Many of the challenges to optimize, improve and perfect the technology, equipment and processes in order to provide an economically viable means of creating sustainable energy were identified in the DOE Stage Gate Review, whose summary report was issued on July 30, 2004.

Risks to farm animals from pathogens in composted catering waste containing meat.

PubMed

Gale, P

2004-07-17

Uncooked meat may contain animal pathogens, including bovine spongiform encephalopathy, foot-and-mouth disease virus, African swine fever virus and classical swine fever virus, and to prevent outbreaks of these diseases in farm animals, the disposal of meat from catering waste is controlled under the Animal By-Products Regulations. This paper estimates the risks to farm animals of grazing land on to which compost, produced by the composting of catering waste containing meat, has been applied. The factors controlling the level of risk are the separation of the meat at source, the efficiency of the composting process, and the decay and dilution of the pathogens in soil. The net pathogen destruction by the composting process is determined largely by the degree of bypass, and to accommodate the possibility of large joints or even whole carcases being discarded uncooked to catering waste, a time/temperature condition of 60 degrees C for two days is recommended. Where data are lacking, worst-case assumptions have been applied. According to the model, classical swine fever virus constitutes the highest risk, but the assessment shows that a two-barrier composting approach, together with a two-month grazing ban, reduces the risk to one infection in pigs every 190 years in England and Wales. This work defined the operational conditions for the composting of catering waste as set out in the Animal By-Products Regulations 2003 (SI 1482).

Quality vs. quantity: assessing the visibility of the jaguars housed at Chester Zoo, UK.

PubMed

Turnock, Suzanne; Moss, Andrew

2015-01-01

To fulfill an educational or visitor-related role in the zoo's collection, a species needs to be visible to the visiting public. However, this may not always be achievable for animals housed in naturalistic enclosures, particularly species which are highly camouflaged and have an elusive nature, such as jaguars. Four jaguars housed at Chester Zoo (UK) were studied to assess the quality of visibility from the public viewing area and to provide recommendations for assessing visibility to evaluate the educational role of elusive species. Data were recorded on whether the jaguar could be seen, the proportion of the body that was visible and their behavior. The jaguars could be seen 19.5% (i.e. quantity), from the public viewing area, of the observed time. 69.2% of this time the whole of the jaguars' body was on-show and it was possible to observe their behavior during all of these observations. However, when less of the body was visible, the behavior of the jaguars could be observed on significantly fewer occasions (P < .001). When we incorporate behavior and proportion of body into the analysis and look at 'educationally meaningful visibility' (i.e. whole of the animal's body and a behavior could be observed), then the measurement of visibility is reduced to 13.3% (i.e. quality). A simple yes or no, in relation to whether an animal is visible or not, does not give us the detail needed to assess if a species is fulfilling an educational role. Potential solutions to address poor visibility are also discussed. © 2015 Wiley Periodicals, Inc.

The management of African (Loxodonta africana) and Asian (Elephas maximus) elephants in zoos involves a range of practices including feeding, exercise, training, and environmental enrichment. These practices are necessary to meet the elephants' nutritional, healthcare, and husbandry needs. However, these practices are not standardized, resulting in likely variation among zoos as well as differences in the way they are applied to individual elephants within a zoo. To characterize elephant management in North America, we collected survey data from zoos accredited by the Association of Zoos and Aquariums, developed 26 variables, generated population level descriptive statistics, and analyzed them to identify differences attributable to sex and species. Sixty-seven zoos submitted surveys describing the management of 224 elephants and the training experiences of 227 elephants. Asian elephants spent more time managed (defined as interacting directly with staff) than Africans (mean time managed: Asians = 56.9%; Africans = 48.6%; p<0.001), and managed time increased by 20.2% for every year of age for both species. Enrichment, feeding, and exercise programs were evaluated using diversity indices, with mean scores across zoos in the midrange for these measures. There were an average of 7.2 feedings every 24-hour period, with only 1.2 occurring during the nighttime. Feeding schedules were predictable at 47.5% of zoos. We also calculated the relative use of rewarding and aversive techniques employed during training interactions. The population median was seven on a scale from one (representing only aversive stimuli) to nine (representing only rewarding stimuli). The results of our study provide essential information for understanding management variation that could be relevant to welfare. Furthermore, the variables we created have been used in subsequent elephant welfare analyses.

1995-01-01

A biocalorimeter and waste management system is provided for making metabolic heat release measurements of animals or humans in a calorimeter (enclosure) using ambient air as a low velocity source of ventilating air through the enclosure. A shroud forces ventilating air to pass over the enclosure from an end open to ambient air at the end of the enclosure opposite its ventilating air inlet end and closed around the inlet end of the enclosure in order to obviate the need for regulating ambient air temperature. Psychrometers for measuring dry- and wet-bulb temperature of ventilating air make it possible to account for the sensible and latent heat additions to the ventilating air. A waste removal system momentarily recirculates high velocity air in a closed circuit through the calorimeter wherein a sudden rise in moisture is detected in the ventilating air from the outlet.

Low pathogenic influenza A virus activity at avian interfaces in Ohio zoos, 2006-2009.

This investigation to examine influenza A virus activity in avian species at four Ohio zoos was initiated to better understand the ecology of avian-origin influenza A (AIV) virus in wild aquatic birds and the possibility of spill-over of such viruses into captive zoo birds, both native and foreign species. Virus isolation efforts resulted in the recovery of three low pathogenic (LP) AIV isolates (one H7N3 and two H3N6) from oral-pharyngeal or cloacal swabs collected from over 1000 zoo birds representing 94 species. In addition, 21 LPAIV isolates possessing H3N6, H4N6, or H7N3 subtype combinations were recovered from 627 (3.3%) environmental fecal samples collected from outdoor habitats accessible to zoo and wild birds. Analysis of oral-pharyngeal and cloacal swabs collected from free-ranging mallards (Anas platyrhynchos) live-trapped at one zoo in 2007 resulted in the recovery of 164 LPAIV isolates (48% of samples) representing five HA and six NA subtypes and at least nine HA-NA combinations. The high frequency of isolate recovery is undoubtedly due to the capture and holding of wild ducks in a common pen before relocation. Serologic analyses using an agar gel immune diffusion assay detected antibodies to the influenza A virus type-specific antigen in 147 of 1237 (11.9%) zoo bird sera and in 14 of 154 (9%) wild mallard sera. Additional analyses of a limited number of zoo bird sera demonstrated HA- and NA-inhibition activity to 15 HA and nine NA subtypes. The spectrum of HA antibodies indicate antibody diversity of AIV infecting zoo birds; however, the contribution of heterologous cross-reactions and steric interference was not ruled out. This proactive investigation documented that antigenically diverse LPAIVs were active in all three components of the avian zoologic-wild bird interfaces at Ohio zoos (zoo birds, the environment, and wild birds). The resulting baseline data provides insight and justification for preventive medicine strategies for zoo birds.

Leptospirosis on captive wild animals in Latin America.

PubMed

Vieira, Anahi S; Lilenbaum, Walter

2017-12-01

Leptospirosis is a worldwide bacterial infection, being more prevalent in tropical regions. Human beings, domestic animals and wildlife species are susceptible to a wide variety of serovars. Zoos have a great importance in keeping endangered species, increasing populations and accumulating knowledge on these species. Although some studies describe the occurrence of leptospirosis in captivity animals, a systematic review regarding the infection in these animals in tropical areas has never been conducted. Thus, the objective of this study was to systematically gather and analyze data regarding leptospirosis among captive wild animals in Latin America. A total of 141 species were studied, 93 genus, 44 families and 15 orders from three classes. Median seroprevalence ranged from 0 to 52% and predominant serogroups were Canicola and Icterohaemorrhagiae for mammalian, and Sejroe for reptiles. One important outcome is that, when kept on zoos, wildlife is more frequently infected by incidental strains instead of adapted strains. Preventive measures should consider periodic serosurvey of all animal species in captivity, as well as the use of commercial vaccines to reduce leptospiral infection and its hazards.

A multi-zoo investigation of nutrient provision for captive red-crested turacos.

PubMed

Hulbert, Alexander J; Hunt, Kerry A; Rose, Paul E

2017-03-01

Turacos (Musophagidae) are common zoo birds; the 14 species of Tauraco being most often exhibited. Turacos possess unique non-structural, copper-based feather pigments, and a specialized dietary strategy. Tauraco inhabit tropical woodlands, foraging for predominantly folivorous and/or frugivorous food items. Using a study population of 16 red-crested turacos (T. erythrolophus) at seven zoos in the United Kingdom, the nutrient composition of diets from diet sheets was calculated, using Zootrition v.2.6, Saint Louis Zoo, USA for analyses of important nutrients within each diet, and compared against an example of currently available literature. For all nutrients analyzed, significant differences were noted between amounts presented in each zoo's diet (as fed). Turacos are presented with a wide range of ingredients in diets fed, and all zoos use domestic fruits to a large extent in captive diets. Similarities exist between zoos when comparing amounts of as-fed fiber. Analysis of the calcium to phosphorous ratio for these diets showed there to be no significant difference from the published ratio available. While this is a small-scale study on only a limited number of zoos, it provides useful information on current feeding practice for a commonly-housed species of bird and highlights potential areas of deviation away from standard practice, as well as identifying ways of reducing wastage of food. Data on wild foraging behavior and food selection, or collaboration with tauraco keepers from institutions in the tropics, is recommended as a way of improving feeding regimes and updating feeding practice for this and other Tauraco species. © 2017 Wiley Periodicals, Inc.

Weather sensitivity for zoo visitation in Toronto, Canada: a quantitative analysis of historical data.

PubMed

Hewer, Micah J; Gough, William A

2016-11-01

Based on a case study of the Toronto Zoo (Canada), multivariate regression analysis, involving both climatic and social variables, was employed to assess the relationship between daily weather and visitation. Zoo visitation was most sensitive to weather variability during the shoulder season, followed by the off-season and, then, the peak season. Temperature was the most influential weather variable in relation to zoo visitation, followed by precipitation and, then, wind speed. The intensity and direction of the social and climatic variables varied between seasons. Temperatures exceeding 26 °C during the shoulder season and 28 °C during the peak season suggested a behavioural threshold associated with zoo visitation, with conditions becoming too warm for certain segments of the zoo visitor market, causing visitor numbers to decline. Even light amounts of precipitation caused average visitor numbers to decline by nearly 50 %. Increasing wind speeds also demonstrated a negative influence on zoo visitation.

With increased scrutiny surrounding the welfare of elephants in zoological institutions, it is important to have empirical evidence on their current welfare status. If elephants are not receiving adequate exercise, it could lead to obesity, which can lead to many issues including acyclicity and potentially heart disease. The goal of the current study was to compare the walking rates of elephants in the wild versus elephants in zoos to determine if elephants are walking similar distances relative to their wild counterparts. Eleven wild elephants throughout different habitats and locations in Botswana were compared to 8 elephants at the San Diego Zoo Safari Park. Direct comparisons revealed no significant difference in average walking rates of zoo elephants when compared with wild elephants. These results suggest that elephants at the San Diego Zoo Safari Park walk similar rates to those of wild elephants and may be meeting their exercise needs.

Zoos serve as centers for both research and education. The challenge is to convey messages about their conservation projects while meeting visitor expectations, which often include recreation and entertainment. One way this can be achieved is through the design of immersive exhibits that draw visitors in and engage them with interactive educational elements. Regenstein African Journey (RAJ) opened at Lincoln Park Zoo in 2003 and was designed to take visitors on a simulated safari through Africa. Because visitor experience was a major design goal, we conducted a timing and tracking study to evaluate use of the building and educational components. For a 9-week period in 2003, we tracked 338 visitors to RAJ and recorded continuous data as they moved through the building. Data were collected on handheld computers that provided precise timing data. The median visit was 11.08 min, 41% of which was spent looking at animals and 9% of which was spent engaged with interpretive elements. We found significant differences in the way visitors used signage: those in groups without children spent more of their visit engaged with signage than those with children and visitors who spent more of their visit interacting socially spent less time engaged with signage. By understanding how visitors use the educational opportunities presented to them, we can better meet their expectations and more effectively achieve the goal of conservation education.

A field trip to the local zoo is often a staple in many elementary school curricula. Many zoos offer free entry to local teachers and their students. Teachers take students on field trips to enrich the curriculum, make connections to what students are learning in school, and provide students with meaningful learning experiences (Kisiel 2007).…

Designing and validating instruments for identifying public health problems in some zoological parks in Colombia, thereby allowing them to be evaluated. Four instruments were designed and validated along with the participation of five zoos. The instruments were validated regarding appearance, content, sensitivity to change, reliability tests and determining the tools' usefulness. An evaluation scale was created which assigned a maximum of 400 points, having the following evaluation intervals: 350-400 points meant good public health management, 100-349 points for regular management and 0-99 points for deficient management. The instruments were applied to the five zoos as part of the validation, forming a base-line for future evaluation of public health in them. Four valid and useful instruments were obtained for evaluating public health in zoos in Colombia. The five zoos presented regular public health management. The base-line obtained when validating the instruments led to identifying strengths and weaknesses regarding public health management in the zoos. The instruments obtained generally and specifically evaluated public health management; they led to diagnosing, identifying, quantifying and scoring zoos in Colombia in terms of public health. The base-line provided a starting point for making comparisons and enabling future follow-up of public health in Colombian zoos.

Environmental enrichment techniques present animals with cognitive challenges while providing them opportunities to make choices and exert control over their environment. In this way, cognitive research and training is enriching to animals and can be used as a form of enrichment in zoos and aquariums. Cognitive research demonstrations also provide an opportunity to enhance visitor experience, as well as foster interactions between animals and keepers. We investigated how cognitive research sessions involving eastern box turtles (Terrapene carolina carolina) at Disney's Animal Kingdom ® impacted both the rate of visitors coming to the exhibit and the amount of time they spent engaged. Further, we used a questionnaire to assess the impact of keeper participation in these sessions on their relationships with and perceptions of the turtles. While visitation rate to the exhibit was not impacted, cognitive research sessions held visitor attention for longer than keeper interpretation or at times during which no keepers or researchers were present. We also found that keepers that had worked with the turtles for longer and keepers that regularly participated in cognitive research sessions reported stronger bonds with the turtles. Our research suggests that use of cognitive research and training demonstrations for guest viewing in zoos and aquariums may enhance visitor learning opportunities by increasing the amount of time they spend at the exhibit. Our study also provides evidence that participation in such demonstrations by zoo and aquarium professionals can be related to improved keeper-animal bonds, potentially resulting in better husbandry and enhanced animal welfare. © 2017 Wiley Periodicals, Inc.

Moon Zoo: Educating side-by-side with Doing Science (Invited)

2010-12-01

The Moon Zoo citizen science project (http://www.moonzoo.org) engages individuals - primarily members of the public - in identifying geological (and sometimes technological) features on the lunar surface. Using a flash-based interface that runs in a web browser, users can mark craters, linear features, and even left-behind lunar landers on Lunar Reconnaissance Orbiter images. These science tools are embedded in an environment designed to encourage learning and collaboration. On the main Moon Zoo site users can explore educational content, including video tutorials, articles, glossary terms, and flash interactive activities. Additionally, there is a blog and a forum to encourage collaboration and social learning, and a twitter feed for general communications. Through this suite of software Moon Zoo users can contribute to science while learning about the Moon and geology. The Moon Zoo educational content is designed with one purpose in mind: To make sure that a curious user can find information quickly, easily, and on (or within 1-click of) the Moon Zoo site. The Internet is filled with many excellent lunar educational products, and many high-quality digital products exist in offline archives. Finding desired resources, however, can sometimes be a challenge even for professional educators. In order to make finding content easier, we developed a glossary list and a basic concept map for our website that addresses geology, lunar exploration, observing, and the moon in history and culture, and then we populated these terms and concepts with already available materials. We also do things in a way that encourages both doing science tasks and learning at the same time! Specifically, we use pop-out audio and video players that allow users to listen, learn, and classify the lunar surface all at once. To try and understand our users better we are conducting both learning and motivations studies while also monitoring site usage. Our learning assessments use an assessment tool

A retrospective study was conducted to evaluate disease patterns in birds at the Detroit Zoo from 1973 through 1983. Data were derived from the zoo's medical and animal census records; the mean (+/- SD) population of birds during the study period was 469 +/- 42. Overall annual morbidity rates were 12.5% to 21.5%, with spring months having the highest morbidity rates. Annual mortality rates were 3.1% to 15.2%; 23.9% of the deaths were caused by microbial agents (particularly Erysipelothrix rhusiopathiae, hemolytic Escherichia coli, Salmonella spp, Aeromonas spp and Proteus spp), 15.4% by trauma, and 42.5% by nondetermined causes. The mute swan (Cygnus olor), mallard duck (Anas platyrhynchos), common gallinule (Gallinula chloropus), common rhea (Rhea americana), and red-billed hornbill (Tockus erythrorhynchus) were the 5 species most frequently affected of the 1,032 deaths from 1973 through 1983. The most frequently isolated parasites were Microtetramere spp, coccidian species, Diplotriaena spp, and Trichomonia spp.

Global amphibian declines are one of the biggest challenges currently facing the conservation community, and captive breeding is one way to address this crisis. Using information from the International Species Information System zoo network, we examined trends in global zoo amphibian holdings across species, zoo region, and species geographical region of origin from 1994 to 2014. These trends were compared before and after the 2004 Global Amphibian Assessment to assess whether any changes occurred and whether zoo amphibian conservation effort had increased. The numbers of globally threatened species (GTS) and their proportional representation in global zoo holdings increased and this rate of increase was significantly greater after 2004. North American, European, and Oceanian GTS were best represented in zoos globally, and proportions of Oceanian GTS held increased the most since 2004. South American and Asian GTS had the lowest proportional representation in zoos. At a regional zoo level, European zoos held the lowest proportions of GTS, and this proportion did not increase after 2004. Since 1994, the number of species held in viable populations has increased, and these species are distributed among more institutions. However, as of 2014, zoos held 6.2% of globally threatened amphibians, a much smaller figure than for other vertebrate groups and one that falls considerably short of the number of species for which ex situ management may be desirable. Although the increased effort zoos have put into amphibian conservation over the past 20 years is encouraging, more focus is needed on ex situ conservation priority species. This includes building expertise and capacity in countries that hold them and tracking existing conservation efforts if the evidence-based approach to amphibian conservation planning at a global level is to be further developed. © 2015 Society for Conservation Biology.

The main objective of the present study was to determined the occurrence of Encephalitozoon intestinalis, E. hellem, E. cuniculi, and Enterocytozoon bieneusi in Poland in animal faecal using the FISH (Fluorescent In Situ Hybridization) and multiplex FISH techniques. Additional objectives included: (1) identification of animal hosts of microsporidia that are infectious to humans amongst free-ranging, captive, livestock and domestic animals; (2) a molecular analysis of randomly selected parasite isolates and determination of their zoonotic potential; (3) evaluation of the role of animals in the dissemination of microsporidia spores in the environment, and an estimation of the potential risk of infection for other animals and humans. A total of 1340 faecal samples collected from 178 species of animals were examined using conventional staining (chromotrope-2R and calcofluor white M2R staining) and molecular techniques (FISH and multiplex FISH techniques). Microsporidian spores were detected in 33 faecal samples (2.5%) obtained from 17 animal species. Microsporidia were demonstrated more often in birds (6.1%) than in mammals (0.7%); the difference was statistically significant (p < 0.00001). In addition, the prevalence of microsporidian infections in waterfowl was significantly higher than the prevalence of microsporidian infections in other animals (p < 0.03). Animal reservoirs of human infectious microsporidia were disclosed in six of 38 sites where faecal samples were taken from animals. Three species of human virulent microsporidia were identified in animals. Spores of E. hellem were found in 25 faecal samples (1.9%) taken from 12 bird species (6 zoo bird species, 4 free-ranging bird species, 2 livestock bird species). Spores of E. intestinalis were identified in five faecal samples (0.4%) taken from two livestock bird species and two zoo mammal species. In turn, E. bieneusi spores were detected only in three faecal samples (0.2%) taken from three zoo mammal species

Maintaining adequate welfare in captive elephants is challenging. Few studies have investigated overnight rest behavior in zoo elephants, yet time spent resting has been identified as a welfare indicator in some species. We investigated resting behavior in Asian elephants (Elephas maximus) in UK zoos, with the aim of identifying patterns or preferences in lying rest. Details of standing (SR) and lying (LR) rest behavior were identified by observing video footage of inside enclosures collected for 14 elephants (2 male, 12 female) housed at three UK zoos (Zoo A: 18 nights; Zoo B: 27 nights; Zoo C: 46 nights) from 16:00 to 08:30 (approximately). Elephants engaged in a mean of 58-337 min rest per night. Time of night affected mean duration of LR bouts (P < 0.001); longest bouts were observed between 22:01 and 06:00. Elephants showed a substrate preference when lying to rest; LR was not observed on concrete or tiled flooring. Where sand was available (to 11/14 elephants), all elephants engaged in LR on sand flooring. Only two elephants engaged in LR on rubber flooring (available to 7/14 elephants). Mean duration of rest bouts was greater when a conspecific was within two body lengths than when conspecifics were not (P < 0.01). Our study indicated that elephants show substrate preferences when choosing an area for rest and engage in more rest when conspecifics are in close proximity. The results of this study could be used as a basis for future studies investigating the link between rest and welfare in captive elephants. © 2015 Wiley Periodicals, Inc.

Cryptoccosis--systemic mycosis caused by Cryptococcus species--has considerably raised its incidence in the last years, mainly associated with the human immunodeficiency virus infection. It has also been described in animals, but rare cases. a case of a female cheetah (Acinonyx jubatus) kept in the Nacional Zoo of Havana was presented. The animal came from South Africa. She began losing weight, and suffering asthenia, anorexia and breathing problems with abundant nasal secretion. mycological testing of these secretions disclosed the presence of serotype B Cryptococcus gattii. Because of the origin and captive condition of the animal, it was believed that the infection had been latent for 16 months at least. up to the present, in Cuba, all clinical Cryptococcus isolates were C. neoformans var. grubii, so it is considered that the infection was caught in the country of origin of the female cheetah. This is the first C. gattii isolate in Cuba from an animal coming from South Africa where this fungus is endemic.

Our ongoing research program is examining the motivations of participants in the Galaxy Zoo citizen science project. At the 2009 AAS summer meeting, we presented preliminary results from a survey taken by more than 10,000 participants of the original Galaxy Zoo. We are continuing to analyze data from this survey. Galaxy Zoo is an online citizen science project in which more than 230,000 participants have classified the morphologies of galaxies. The original Galaxy Zoo, in which participants classified galaxies as elliptical or spiral, has led to more than a dozen science journal papers published or in peer review. In our research, we have found that Galaxy Zoo participants are mostly male and represent a wide range of ages and educations. They are primarily motivated by a desire to contribute to scientific research (40%), interest in astronomy (13%), and looking at beautiful galaxy images (10%). In this poster, we present results from free response data. Each question about motivation included an "Other" response where participants could indicate that their motivation for participating was not included in the survey instrument. By analyzing these "Other" responses, we can ensure that we have a complete list of motivations present in the Galaxy Zoo participant population, and we can also gain insight into what other populations might be recruited to participate in Galaxy Zoo. We have had multiple raters analyze these "Other" responses. We have uncovered new motivations at a very low level in our sample - for example, a "religious/spiritual" motivation that was indicated by 5 of the 205 people who entered text in the "Other" field (from among the 10,000 survey respondents). In this poster, we will present results from this analysis of the "Other" motivations, as well as results from analyzing our full dataset.

Evaluating the contribution of zoos and aquariums to Aichi Biodiversity Target 1.

The United Nations Strategic Plan for Biodiversity 2011-2020 is a key initiative within global efforts to halt and eventually reverse the loss of biodiversity. The very first target of this plan states that "by 2020, at the latest, people are aware of the values of biodiversity and the steps they can take to conserve and use it sustainably." Zoos and aquariums worldwide, attracting more than 700 million visits every year, could potentially make a positive contribution to this target. However, a global evaluation of the educational impacts of visits to zoos and aquariums is entirely lacking in the existing literature. To address this gap, we conducted a large-scale impact evaluation study. We used a pre- and postvisit repeated-measures survey design to evaluate biodiversity literacy-understanding of biodiversity and knowledge of actions to help protect it-of zoo and aquarium visitors worldwide. Ours was the largest and most international study of zoo and aquarium visitors ever conducted. In total, 5661 visitors to 26 zoos and aquariums from 19 countries around the globe participated in the study. Aggregate biodiversity understanding and knowledge of actions to help protect biodiversity both significantly increased over the course of zoo and aquarium visits. There was an increase from previsit (69.8%) to postvisit (75.1%) in respondents demonstrating at least some positive evidence of biodiversity understanding. Similarly, there was an increase from previsit (50.5%) to postvisit (58.8%) in respondents who could identify actions to help protect biodiversity that could be achieved at an individual level. Our results are the most compelling evidence to date that zoo and aquarium visits contribute to increasing the number of people who understand biodiversity and know actions they can take to help protect biodiversity. © 2014 Society for Conservation Biology.

Upper respiratory tract disease (URTD) is a significant cause of morbidity in captive orangutans (Pongo abelii, Pongo pygmaeus), and the pathogenesis is often unknown.  The prevalence of respiratory disease in captive European orangutans (201 animals; 20 zoos) and possible predisposing factors were investigated. Bornean orangutans (P. pygmaeus) showed chronic respiratory signs significantly more often (13.8%) than Sumatran (P. abelii; 3.6%), and males (15.8%) were more often afflicted than females (3.9%). Hand-reared animals (21%) developed air sacculitis more often than parent-reared animals (5%). Diseased animals were more often genetically related to animals with respiratory diseases (93%) than to healthy animals (54%). None of the environmental conditions investigated had a significant effect on disease prevalence. Results suggest a higher importance of individual factors for the development of URTD than environmental conditions. Bornean, male and hand-reared orangutans and animals related to diseased animals need increased medical surveillance for early detection of respiratory disease. © 2011 University of Zurich.

Glucocorticoid quantification using non-invasive methods provides a powerful tool for assessing the health and welfare of wildlife in zoo-based programmes. In this study, we provide baseline data on faecal-based glucocorticoid (cortisol) monitoring of Sumatran tigers (Panthera tigris ssp. sumatrae) managed at the Melbourne Zoo in Victoria, Australia. We sampled five tigers daily for 60 days. Faecal cortisol metabolites (FCMs) in tiger faecal extracts were quantified using enzyme immunoassays that were successfully validated using parallelism and accuracy recovery checks. Two female tigers had significantly higher mean FCM levels than the two males and another female, suggesting that females may have higher FCM levels. A significant elevation was noted in the FCM levels for one female 2 days after she was darted and anaesthetized; however, the FCM levels returned to baseline levels within 3 days after the event. Comparative analysis of FCM levels of tigers sampled at Melbourne Zoo with tigers sampled earlier at two other Australian Zoos (Dreamworld Themepark and Australia Zoo) showed that FCM levels varied between zoos. Differences in the enclosure characteristics, timing of sampling, size and composition of groupings and training procedures could all contribute to this variation. Overall, we recommend the use of non-invasive sampling for the assessment of adrenocortical activity of felids managed in zoos in Australia and internationally in order to improve the welfare of these charismatic big cats.

We present a new way of exploring your favorite Galaxy Zoo galaxies within the context of the sky using Microsoft Research's WorldWide Telescope. Galaxy Zoo has a fantastic community that is eager to learn and contribute to science through morphological classifications of galaxies. WorldWide Telescope is an interactive observatory that allows users to explore the sky. WorldWide Telescope uses images from the world's best telescopes, including the galaxies of the Sloan Digital Sky Survey. WorldWide Telescope provides a fantastic sense of size and distance that is hard to experience in Galaxy Zoo. Creating tours from favorite galaxies directly from Galaxy Zoo aims to solve this dilemma.The incorporation of Galaxy Zoo and WorldWide telescope provides a great resource for users to learn more about the galaxies they are classifying. Users can now explore the areas around certain galaxies and view information about that location from within WorldWide Telescope. Not only does this encourage self-motivated research but after tours are created they can be shared with anyone. We hope this will help spread citizen science to different audiences via email, Facebook, and Twitter.Without the WorldWide Telescope team at Microsoft Research this project would not have been possible. Please go start exploring at http://wwt.galaxyzoo.org. This project was funded through the Microsoft Research Academic Program.

2017-01-01

While seasonality has often been investigated with respect to reproduction, seasonality of mortality has received less attention. We investigated whether a seasonal signal of mortality exists in wild ruminants kept in zoos, using data from 60,591 individuals of 88 species. We quantified the mortality in the 3 consecutive months with the highest above-baseline mortality (3 MM). 3 MM was not related to relative life expectancy of species, indicating that seasonal mortality does not necessarily impact husbandry success. Although 3 MM was mainly observed in autumn/winter months, there was no evidence for an expected negative relationship with the latitude of the species' natural habitat and no positive relationship between 3 MM and the mean temperature in that habitat, indicating no evidence for species from lower latitudes/warmer climates being more susceptible to seasonal mortality under zoo conditions. 3 MM was related to reproductive biology, with seasonally reproducing species also displaying more seasonal mortality. This pattern differed between groups: In cervids, the onset of seasonal mortality appeared linked to the onset of rut in both sexes. This was less evident in bovids, where in a number of species (especially caprids), the onset of female seasonal mortality was linked to the lambing period. While showing that the origin of a species from warmer climate zones does not constrain husbandry success in ruminants in terms of an increased seasonal mortality, the results suggest that husbandry measures aimed at protecting females from rutting males are important, especially in cervids.

Health data for free-living eastern box turtles (Terrapene carolina carolina) at the Maryland Zoo in Baltimore were analyzed. One hundred and eighteen turtles were captured on or near zoo grounds over the course of 15 yr (1996-2011), with recapture of many individuals leading to 208 total evaluations. Of the 118 individuals, 61 were male, 50 were female, and 7 were of undetermined sex. Of the 208 captures, 188 were healthy, and 20 were sick or injured. Complete health evaluations were performed on 30 turtles with physical examination records, complete blood counts (CBCs), and plasma biochemistry profiles. Eight animals were sampled more than once, yielding 40 total samples for complete health evaluations of these 30 individuals. The 40 samples were divided into healthy (N=29) and sick (N=11) groups based on clinical findings on physical examination. Samples from healthy animals were further divided into male (N=17) and female (N= 12) groups. CBC and biochemistry profile parameters were compared between sick and healthy groups and between healthy males and females. Sick turtles had lower albumin, globulin, total protein (TP), calcium, phosphorous, sodium, and potassium than healthy animals. Sick turtles also had higher heterophil to lymphocyte ratios. Healthy female turtles had higher leukocyte count, eosinophil count, total solids, TP, globulin, cholesterol, calcium, and phosphorous than healthy males. Banked plasma from all 40 samples was tested for antibodies to Mycoplasma agassizii and Mycoplasma testudineum via enzyme-linked immunosorbent assay. One sample from a clinically healthy female was antibody positive for M. agassizii; none were positive for M. testudineum. This study provides descriptive health data for eastern box turtles and CBC and biochemistry profile information for T. carolina carolina at and near the Maryland Zoo in Baltimore. It also reports low serologic evidence of exposure to mycoplasmosis.

Galaxy Zoo (www.galaxyzoo.org) is familiar to many as a hugely successful citizen science project. Hundreds of thousands of members of the public have contributed to Galaxy Zoo which collects visual classifications of galaxies in images from a variety of surveys (e.g. the Sloan Digital Sky Survey, Hubble Space Telescope surveys, and others) using an internet tool. Galaxy Zoo inspired the creation of "The Zooniverse" (www.zooniverse.org) which is now the world's leading online platform for citizens science, hosting a growing number of projects (at the time of writing ~30) making use of crowdsourced data analysis in all areas of academic research, and boasting over 1.3 million participants.Galaxy Zoo has also shown itself, in a series of (now ~60) peer reviewed papers, to be a fantastic database for the study of galaxy evolution. Participation in citizen science is also fantastic public engagement with scientific research. But what do the participants learn while they are involved in crowdsourced data analysis?In this talk I will discuss how public engagement via citizen science can be an effective means of outreach from data intensive astronomical surveys. A citizen science project (if done right) can and should increase the scientific output of an astronomical project, while at the same time inspiring participants to learn more about the science and techniques of astronomy.

The article shows the possibility of using the electromagnetic field of ultrahigh frequency (EMF UHF) for drying and disinfecting of such animal waste as pig manure and poultry droppings. The studied modes included the following options: processing exposure of 60, 90, 120 sec, the capacity of 60 kW, the frequency of 915 MHz. The method of UHF processing of manure and poultry droppings is environmentally safe and effective in neutralizing the pathogenic microflora, as well as larvae and eggs of worms. The following processing mode of animal waste in the electromagnetic field of ultrahigh frequency was recognized as optimal: exposure of 90 seconds, the capacity of 60 kW, the frequency of 915 MHz. This option leads to the complete destruction of pathogenic and conditionally pathogenic microorganisms, as well as the eggs and larvae of worms. As a result of this processing, a high level of microbiological safety of pig manure and poultry droppings is achieved that allows using them as organic fertilizers. The peculiarities of some species of pathogenic fungi developing on the surface of the wheat grain are shown. Pre-processed animal waste (pig manure and and poultry droppings) were applied in experimental variants. Used organic fertilizers underwent electromagnetic processing of ultra-high frequency. The qualitative composition of the microflora on the surface of the grain depends on the type of animal waste (manure or droppings) and used dose. The safest part of the microflora of grain was marked with the application of the UHF-processed pig manure and poultry droppings in doses of 10 t/ha.

In 2013, public health officials in Multnomah County, Oregon, started an investigation of a tuberculosis (TB) outbreak among elephants and humans at a local zoo. The investigation ultimately identified three bull elephants with active TB and 118 human contacts of the elephants. Ninety-six (81%) contacts were evaluated, and seven close contacts were found to have latent TB infection. The three bulls were isolated and treated (elephants with TB typically are not euthanized) to prevent infection of other animals and humans, and persons with latent infection were offered treatment. Improved TB screening methods for elephants are needed to prevent exposure of human contacts.

SUMMARY Hepatitis E virus (HEV) is a zoonotic pathogen of which several species of animals are considered to be reservoirs. Thirty-eight faecal samples, obtained from 22 species of animals including birds in a wildlife first-aid centre in Eastern China, were tested for HEV RNA. Our survey revealed that in total 28·9% (95% confidence interval 14·5–43·4) of the faecal samples from various mammals and birds were HEV RNA positive. Sequence and phylogenetic analyses of the 11 isolates demonstrated that all sequences clustered in genotype 4 with 96–100% identity to each other. In addition, serum samples from seven animal handlers have shown that five (71·4%) were seropositive. The findings imply that cross-species infection of HEV had probably occurred in this zoo-like location, and moreover, birds can be infected naturally with mammalian HEV. PMID:17961279

2016-05-01

This study assesses the suitability of vegetable waste produced by food industry for use as a raw material for animal feed. It includes safety and nutritional viability, technical feasibility and environmental evaluation. Vegetable by-products were found to be nutritionally and sanitarily appropriate for use in animal feed. The drying technologies tested for making vegetable waste suitable for use in the animal feed market were pulse combustion drying, oven and microwave. The different meal prototypes obtained were found to comply with all the requirements of the animal feed market. An action plan that takes into account all the stages of the valorisation process was subsequently defined in agreement with local stakeholders. This plan was validated in a pilot-scale demonstration trial. Finally, the technical feasibility was studied and environmental improvement was performed. This project was funded by the European LIFE+ program (LIFE09 ENV/ES/000473). Copyright © 2015 Elsevier Ltd. All rights reserved.

Habitat characteristics of larval mosquitoes in zoos of South Carolina, USA.

Tuten, Holly C

2011-06-01

To investigate whether the unique assemblage of habitats in zoos could affect mosquito oviposition behavior and to provide zoos with suggestions for mosquito control, larvae were sampled and associated habitat variables were measured in 2 zoos in South Carolina, U.S.A. Fifty-nine sites were sampled from March 2008 to January 2009. A total of 1630 larvae representing 16 species was collected and identified. The dominant species was Aedes albopictus (46.0%), followed by Ae. triseriatus (23.6%), Culex restuans (12.4%), and Cx. pipiens complex (9.7%). Principal components and multiple logistic regression analyses showed that across both zoos the distribution of Ae. albopictus larvae was predicted by ambient and site temperature, precipitation, dissolved oxygen, and container habitats. The distribution of Ae. triseriatus larvae was predicted by natural containers and shade height < or =2 m. Overall larval mosquito presence (regardless of species) was predicted by ambient and site temperature, precipitation, dissolved oxygen, presence of natural habitats, and absence of aquatic vegetation. Additionally, C8 values of pairwise species associations indicated significant habitat-based relationships between Ae. albopictus and Ae. triseriatus, and Cx. pipiens complex and Cx. restuans. In general, species-habitat associations conformed to previously published studies. Recommendations to zoo personnel include elimination of artificial container habitats, reduction of shade sources < or =2 m over aquatic habitats, use of approved mosquito larvicides, and training in recognizing and mitigating larval mosquito habitats.

Visitor circulation and nonhuman animal welfare: an overlooked variable?

PubMed

Davey, Gareth; Henzi, Peter

2004-01-01

This article investigates visitor circulation and behaviors within a gallery of primate exhibits in relation to their possible implications for nonhuman animal welfare. When entering a primate house, the majority of visitors (84%) turned right, a pattern upheld throughout all times of the day. These findings demonstrate the existence of the "right-turn" principle, a concept previously identified and investigated in the museum setting. The existence of this circulation pattern in zoos has important implications for the practical management of animal welfare issues because unbalanced or large numbers of visitors at specific enclosures could present a stressful influence. The "direction bias" could not be attributed to demographic or behavioral traits, therefore suggesting that the principle, like similar findings from museum research, generalizes across visitor populations and, therefore, zoos. A visitor sample at another exhibit (located outside the exhibit gallery) did not display a direction bias, suggesting that the marked circulation pattern may be specific to exhibit galleries. The article discusses the significance and consequences of visitor circulation with respect to visitor management and animal welfare.

Skin diseases affect millions of people and animals worldwide, including Asian elephants. This study sought to determine the pathogen of skin diseases that occurred in Asian elephants in Chongqing Zoo, China. The isolated fungus was identified through its cultural characteristics, morphology, and polymerase chain reaction (PCR) amplification. The PCR amplification using common fungal primers (ITS1 and ITS4) determined that the pathogen was 99.7% homologous to Microsporum canis. This is the first report on elephants infected with Microsporum canis in China.

Rodhain, F

A large number of zoo-anthroponoses is known, in the natural cycle of which are involved rodents or lagomorphs. This is mainly related to the numerical importance of rodents, their ecological plasticity, their relationships with man. Thus, it is important, for the epidemiologist, to differentiate synanthropic rodents living in close contact with man and often spread by him, which are at the origine of frequently urban diseases, from wild rodents usually having only few contacts with man in rural areas only. The events allowing the passage of an infectious agent from rodent to man appear varied, as are epidemiological schemes in which these animals can play different roles: they can act, alone or together with other animals, as natural reservoirs, or, on the contrary, they are only occasionally infected, and the transmission can occur by direct contact, by bite, through the environment, or with the help of an arthropod vector. It is particularly interesting to follow the evolution of some of these epidemiological systems, in order to evaluate the impact of human activities, such as deforestations, new technics for agriculture and cattle breeding, urbanization, increasing transportation, development of leisure activities. In order to reduce this infectious risk, we should look for the means of a correct balance between rodent and human populations, by joining the control of epidemiologically dangerous species, modification of some of our behaviours, a relevant health information, together with the care of the protection of natural ecosystems.

From Waste to Watts: The fermentation of animal waste occuring in a digester producing methane gasses as a side product and converted to energy.

Weiss, S.

2015-12-01

The waste product from animals is readily available all over the world, including third world countries. Using animal waste to produce green energy would allow low cost energy sources and give independence from fossil fuels. But which animal produces the most methane and how hard is it to harvest? Before starting this experiment I knew that some cow farms in the northern part of the Central California basin were using some of the methane from the waste to power their machinery as a safer, cheaper and greener source through the harnessed methane gas in a digester. The fermentation process would occur in the digester producing methane gasses as a side product. Methane that is collected can later be burned for energy. I have done a lot of research on this experiment and found that many different farm and ranch animals produce methane, but it was unclear which produced the most. I decided to focus my study on the waste from cows, horses, pig and dogs to try to find the most efficient and strongest source of methane from animal waste. I produced an affordable methane digester from plastic containers with a valve to attach a hose. By putting in the waste product and letting it ferment with water, I was able to produce and capture methane, then measure the amount with a Gaslab meter. By showing that it is possible to create energy with this simple digester, it could reduce pollution and make green energy easily available to communities all over the world. Eventually this could result into our sewer systems converting waste to energy, producing an energy source right in your home.

An Interpretive Study of Meanings Citizen Scientists Make When Participating in Galaxy Zoo

As the Web 2.0 world lurches forward, so do intellectual opportunities for students and the general public to meaningfully engage in the scientific enterprise. In an effort to assess the intrinsic motivation afforded by participation in Galaxy Zoo, we have inductively analyzed more than 1,000 contributions in the Galaxy Zoo Forum and coded posts thematically. We find that participants overwhelmingly want to meaningfully contribute to a larger scientific enterprise as well as have seemingly unique access to high quality, professional astronomical data. While other citizen science projects work through large data sets, Galaxy Zoo is unique in its motivations and retention abilities. Many of these motivations originate in the aesthetic power of astronomical images, which Galaxy Zoo successfully harnesses, while not compromising the scientific value of the project. From the data emerged several trends of motivation, the primary being the sense of community created within the project that promotes professional-amateur collaboration; fulfilling a dream of being an astronomer, physicist, or astronaut; tapping into a potential well of interest created during the space race era; the spiritual aspect generated when the imagination interacts with Galaxy Zoo; and, uniting them all, the aesthetic appeal of the galaxy images. In addition, a very powerful tool also emerged as a method of retention unique to Galaxy Zoo. This tool, known as variable ratio reinforcement in behavioral psychology, uses the most appealing images as positive reinforcement to maintain classification rates over time.

2015-01-01

Pangolins are considered difficult to maintain in zoos, often attributed to problems in feeding management. Taipei Zoo's designation as a wildlife rescue center for Chinese pangolins (Manis pentadactyla) has resulted in long term feeding experience with development of diets that support recovery, maintenance, and reproduction, as well as experimental opportunities to further understand digestive physiology to optimize nutrition. Opportunistic dissection of 10 animals revealed details of the tongue, salivary glands, stomach and gastrointestinal tract (GIT), including confirmation of anatomical differences between Asian and African pangolin species. Length of the total GIT relative to body length (∼ 9:1) was greater than found in domestic carnivores, more similar to omnivorous species. Intake and digestion trials conducted with 4 animals demonstrated that pangolins maintained body weights (BW; 6-9 kg) consuming diets containing 32-40% crude protein, 20-25% crude fat, and 13-28% crude fiber (DM basis). Daily DM intakes ranged from ∼40 to 70 g per animal, with digestible energy intake 51.5-87.5 kcal /kg BW(0.75) /day; pangolins consumed 9.4-15.2 g DM/kg BW(0.75) /day. Dietary energy data support observations of low metabolism and maintenance requirements for this species, similar to values reported for other myrmecophageous species. Addition of 5% ground chitin to diets improved fecal consistency, and decreased digestibility of DM, protein, and energy; addition of chitosan (chitin treated with NaOH) resulted in diet rejection. This information may assist in enhancement of captive diets, as well as in controlling obesity in pangolins. © 2015 Wiley Periodicals, Inc.

2014-08-01

The aim of the present study was to evaluate the frequency of antibiotic resistance in Salmonella spp. strains from wild animals in captivity at the Culiacan Zoo and the Mazatlan Aquarium in Sinaloa, Mexico. We identified 17 different Salmonella enterica serovars at a prevalence of 19.90% (Culiacan Zoo) and 6.25% (Mazatlan Aquarium). Antibiotic sensitivity tests revealed that, of the 83 strains studied, 100% were multidrug resistant (MDR). The drugs against which the greatest resistance was observed were: penicillin, erythromycin, dicloxacillin, ampicillin, cephalothin, and chloramphenicol. We therefore conclude that MDR is common among Salmonella isolates originating from wild animals in captivity in Sinaloa.

Faecal samples were individually collected from pet (n = 63) and zoo (n = 83) birds representing 14 orders and 63 species. All the samples were examined by faecal flotation technique. In a subgroup of samples (n = 75), molecular assays were also used to detect Cryptosporidium oocysts and Giardia duodenalis cysts. Overall, 35.6% of the birds harboured parasites (42.2% of zoo birds and 27% of pet birds), including Strongyles-Capillarids (8.9%), Ascaridia (6.8%), Strongyles (5.5%), G. duodenalis Assemblage A (5.3%), Coccidia (4.1%), Cryptosporidium (4%), Porrocaecum (2.7%), Porrocaecum-Capillarids (2%), and Syngamus-Capillarids (0.7%). The zoonotic G. duodenalis Assemblage A and Cryptosporidium were exclusively found in Psittaciformes, with prevalences of 10.3% and 7.7% within this bird group. Zoo birds were more likely to harbor mixed infections (OR = 14.81) and symptomatic birds to be parasitized (OR = 4.72). Clinicians should be aware of the public health implications posed by zoonotic G. duodenalis Assemblages and Cryptosporidium species in captive birds. PMID:22536128

Biting midges of the genus Culicoides (Diptera: Ceratopogonidae) were collected during the summer of 2007 at the Greenville and Riverbanks Zoos in South Carolina with Centers for Disease Control and Prevention (CDC) traps equipped with ultraviolet or incandescent lights and baited with carbon dioxide. Sixteen species of Culicoides were collected, four of which represented more than 80%. They were Culicoides guttipennis (Coquillett), Culicoides mulrenanni Beck, Culicoides obsoletus (Meigen), and Culicoides sanguisuga (Coquillett). C. guttipennis was found on a dead colobus monkey and a dead golden-headed lion tamarin; Culicoides husseyi Wirth & Blanton was collected from an unidentified, abandoned bird's nest. Ultraviolet light-equipped traps captured significantly more Culicoides specimens than traps with incandescent light. Half of the collected species previously have been associated with vertebrate pathogens, indicating a potential risk to captive animals. PMID:20569132

Motivation of Citizen Scientists Participating in Moon Zoo

Moon Zoo is an online citizen science project with the aim of providing detailed crater counts for as much of the Moon's surface as possible. In addition to focusing on craters, volunteers are encouraged to remain vigilant for sightings of atypical features which may lead to new discoveries. Volunteers accomplish these tasks by exploring images captured by NASA's Lunar Reconnaissance Orbiter (LRO) which has a resolution of 50cm per pixel. To be successful, Moon Zoo needs to attract and retain a large population of citizen scientists. In this study, we examine the factors motivating Moon Zoo participants who invest many hours exploring these images. In this, the first of a two-phased study, we conducted a qualitative analysis using semi-structured interviews as a means of data collection. A stratified sample of participants was used in an attempt to uncover the driving forces behind decisions to participate from a wide-range of participants. Inquiring and probing questions were asked about factors which led volunteers to Moon Zoo as well as reasons which kept them committed to exploring the Moon's surface through this online portal. Responses were then categorized using a grounded theory approach, and frequency distributions are calculated where appropriate. Aggregate results from these interviews are presented here including the demographics of the sample and motivators as per the content analysis. The information gathered from this phase will be used to guide the development of an online survey to further explore volunteers’ motivation based on the presented classification schemes. The survey will then be used to guide future research and development in the area of citizen science in the field of astronomy. These findings will also be useful in charting new boundaries for future research.

Almost nothing is known about the natural vocal behavior of lesser galagos living in zoos. This is perhaps because they are usually kept in nocturnal exhibits separated from the visitors by a transparent and acoustically insulating glass barrier. The aim of the present study was therefore to fill this gap in knowledge of the vocal behavior of lesser galagos from zoos. This knowledge might be beneficial because the vocalizations of these small primates can be used for species determination. We performed a 10-day-long acoustic monitoring of vocal activity in each of seven various groups of Galago senegalensis and G. moholi living at four zoos. We quantitatively evaluated the occurrence of four loud vocalization types present in both species, including the most species-specific advertisement call. We found that qualitative as well as quantitative differences exist in the vocal behavior of the studied groups. We confirmed that the observed vocalization types can be collected from lesser galagos living at zoos, and the success can be increased by selecting larger and more diverse groups. We found two distinct patterns of diel vocal activity in the most vocally active groups. G. senegalensis groups were most vocally active at the beginning and at the end of their activity period, whereas one G. moholi group showed an opposite pattern. The latter is surprising, as it is generally accepted that lesser galagos emit advertisement calls especially at dawn and dusk, i.e., at the beginning and at the end of their diel activity. © 2016 Wiley Periodicals, Inc.

The Masoala rainforest hall of the Zurich Zoo, Switzerland, covers a ground surface area of 10,856 m2 and reaches 30 m in height. With its transparent ETFE foiled roof it provides a tropical climate for a large diversity of plants and animals. In combination with an effort to estimate dry deposition of elemental mercury, we made an attempt to measure turbulent transfer velocity with an ultrasonic anemometer inside the hall. Not surprising, the largest turbulence elements were on the order of the hall dimension. Although the dimensions of the hall seem to be small (200,000 m3) for eddy covariance flux measurements and the air circulation inside the hall was extremely weak, the spectra of wind velocity components and virtual (sonic) temperature obeyed the general statistical description expected under unconstrained outdoor measurement conditions. We will present results from a two-week measurement campaign in the Masoala rainforest hall and make a suggestion for the deposition velocity to be used to estimate dry deposition of atmospheric components to the tropical vegetation surface.

In 1995 and 1996, the shedding of Toxoplasma gondii oocysts was monitored in the faeces of Felidae in six zoos in the Czech Republic. In all, 2287 samples of faeces from 19 species of Felidae were examined. In Ostrava Zoo, four episodes of shedding of Toxoplasma-like oocysts were identified, using a flotation examination, in a pair of wild cats (Felis silvestris), six episodes in a wild cat held separately, and three episodes in a pair of Amur leopard cats (F. euptilurus). After the passage of sporulated oocysts through laboratory mice, T. gondii was confirmed in the pair of wild cats (three episodes), in the wild cat held separately (three episodes) and in the pair of Amur leopard cats (one episode). In Jihlava Zoo, one episode of shedding of T. gondii oocyst was identified in Geoffroy's cat (Oncifelis geoffroyi) using flotation and isolation examination. The possible sources of toxoplasmosis of the Felidae in zoos are discussed.

Release and Removal of Microorganisms from Land-Deposited Animal Waste and Animal Manures: A Review of Data and Models.

2015-09-01

Microbial pathogens present a leading cause of impairment to rivers, bays, and estuaries in the United States, and agriculture is often viewed as the major contributor to such contamination. Microbial indicators and pathogens are released from land-applied animal manure during precipitation and irrigation events and are carried in overland and subsurface flow that can reach and contaminate surface waters and ground water used for human recreation and food production. Simulating the release and removal of manure-borne pathogens and indicator microorganisms is an essential component of microbial fate and transport modeling regarding food safety and water quality. Although microbial release controls the quantities of available pathogens and indicators that move toward human exposure, a literature review on this topic is lacking. This critical review on microbial release and subsequent removal from manure and animal waste application areas includes sections on microbial release processes and release-affecting factors, such as differences in the release of microbial species or groups; bacterial attachment in turbid suspensions; animal source; animal waste composition; waste aging; manure application method; manure treatment effect; rainfall intensity, duration, and energy; rainfall recurrence; dissolved salts and temperature; vegetation and soil; and spatial and temporal scale. Differences in microbial release from liquid and solid manures are illustrated, and the influential processes are discussed. Models used for simulating release and removal and current knowledge gaps are presented, and avenues for future research are suggested.

2007-01-01

Waste from agricultural livestock operations has been a long-standing concern with respect to contamination of water resources, particularly in terms of nutrient pollution. However, the recent growth of concentrated animal feeding operations (CAFOs) presents a greater risk to water quality because of both the increased volume of waste and to contaminants that may be present (e.g., antibiotics and other veterinary drugs) that may have both environmental and public health importance. Based on available data, generally accepted livestock waste management practices do not adequately or effectively protect water resources from contamination with excessive nutrients, microbial pathogens, and pharmaceuticals present in the waste. Impacts on surface water sources and wildlife have been documented in many agricultural areas in the United States. Potential impacts on human and environmental health from long-term inadvertent exposure to water contaminated with pharmaceuticals and other compounds are a growing public concern. This workgroup, which is part of the Conference on Environmental Health Impacts of Concentrated Animal Feeding Operations: Anticipating Hazards-Searching for Solutions, identified needs for rigorous ecosystem monitoring in the vicinity of CAFOs and for improved characterization of major toxicants affecting the environment and human health. Last, there is a need to promote and enforce best practices to minimize inputs of nutrients and toxicants from CAFOs into freshwater and marine ecosystems.

2015-11-20

Polyhydroxyalkanoates (PHAs) are biodegradable and biocompatible polyesters considered as alternatives to petroleum-based plastics. Ralstonia eutropha is a model organism for PHA production. Utilizing industrially rendered waste animal fats as inexpensive carbon feedstocks for PHA production is demonstrated here. An emulsification strategy, without any mechanical or chemical pre-treatment, was developed to increase the bioavailability of solid, poorly-consumable fats. Wild type R. eutropha strain H16 produced 79-82% (w/w) polyhydroxybutyrate (PHB) per cell dry weight (CDW) when cultivated on various fats. A productivity of 0.3g PHB/(L × h) with a total PHB production of 24 g/L was achieved using tallow as carbon source. Using a recombinant strain of R. eutropha that produces poly(hydroxybutyrate-co-hydroxyhexanoate) [P(HB-co-HHx)], 49-72% (w/w) of PHA per CDW with a HHx content of 16-27 mol% were produced in shaking flask experiments. The recombinant strain was grown on waste animal fat of the lowest quality available at lab fermenter scale, resulting in 45 g/L CDW with 60% (w/w) PHA per CDW and a productivity of 0.4 g PHA/(L × h). The final HHx content of the polymer was 19 mol%. The use of low quality waste animal fats as an inexpensive carbon feedstock exhibits a high potential to accelerate the commercialization of PHAs.

Enterocytozoon bieneusi is the dominant specie of microsporidia which can infect both anthroponotic and zoonotic species. The golden snub-nosed monkey is an endangered primate which can also infect by E. bieneusi. To date, few genetic data on E. bieneusi from golden snub-nosed monkeys has been published. Therefore, to clarify the prevalence and genotypes of E. bieneusi in captive golden snub-nosed monkeys is necessary to assess the potential for zoonotic transmission. We examined 160 golden snub-nosed monkeys from six zoos in four cities in China, using PCR and comparative sequence analysis of the ribosomal internal transcribed spacer (ITS). The overall prevalence of E. bieneusi was 46.2% (74/160); while the prevalence was 26.7%, 69.1%, 69.4% and 33.3% in Shanghai Zoo, Shanghai Wild Animal Park, Tongling Zoo, and Taiyuan Zoo respectively (P = 0.006). A total of seven E. bieneusi genotypes were found that included four known (D, J, CHG1, and CHG14) and three new (CM19-CM 21) genotypes. The most common genotype was D (54/74, 73.0%), followed by J (14/74, 18.9%); other genotypes were restricted to one or two samples. Phylogenetic analysis revealed that genotype D belonged to the previously-characterized Group 1, with zoonotic potential; whereas genotypes J, CHG1, CHG14 and CM19-CM 21 clustered in the previously-characterized Group 2, the so-called cattle host specificity group. The findings of high prevalence of zoonotic E. bieneusi genotypes D and J in golden snub-nosed monkeys suggest that golden snub-nosed monkeys may be the reservoir hosts for human microsporidiosis, and vice versa.

Understanding the basic reproductive biology and limitations to successful breeding of the southern three-banded armadillo (Tolypeutes matacus) is necessary to maintain viable zoo populations. Our objectives were to: 1) describe the reproductive biology using non-invasive, fecal hormone analysis; 2) assess influence of season on gonadal hormonal patterns in both the sexes; 3) characterize reproductive cyclicity and pregnancy in the female; and 4) characterize the onset of sexual maturity in males. Nineteen armadillos were monitored including: 13 (7 males, 6 females) from Lincoln Park Zoo and six (3 males, 3 females) from San Antonio Zoological Garden. Fecal samples (n=5220; 275/animal/yr) were collected 5 to 7 times a week for 1 year. Hormones were extracted from feces and analyzed for progestagen (females) and androgen (males) metabolite concentrations using enzyme immunoassays. Mean estrous cycle length (26.4±1.3 days) did not vary (P<0.05) among individuals (n=9). Mean gestation length (n=3) was 114.0±0.6 days long with mean fecal progestagen metabolites increasing 10-fold during pregnancy. Seasons did not influence (P<0.05) fecal androgen or progestagen metabolites. These data can assist with management decisions, which will directly affect the success of this species in zoos.

Emerging infectious diseases are increasingly originating from wildlife. Many of these diseases have significant impacts on human health, domestic animal health, and biodiversity. Surveillance is the key to early detection of emerging diseases. A zoo based wildlife disease surveillance program developed in Australia incorporates disease information from free-ranging wildlife into the existing national wildlife health information system. This program uses a collaborative approach and provides a strong model for a disease surveillance program for free-ranging wildlife that enhances the national capacity for early detection of emerging diseases.

The bonobo, Pan paniscus, is one of the most endangered primate species. In the context of the Bonobo Species Survival Plan(®), the Milwaukee County Zoo established a successful breeding group. Although the bonobo serves as a model species for human evolution, no prenatal growth curves are available. To develop growth graphs, the animals at the Milwaukee County Zoo were trained by positive reinforcement to allow for ultrasound exams without restraint. With this method, the well being of mother and fetus were maintained and ultrasound exams could be performed frequently. The ovulation date of the four animals in the study was determined exactly so that gestational age was known for each examination. Measurements of biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC), and femur length (FL) were used to create growth curves. Prenatal growth of P. paniscus was compared with the data of humans and the common chimpanzee, P. troglodytes. With respect to cranial structures, such as BPD and HC, humans have significant acceleration of growth compared with P. paniscus and P. troglodytes. In P. paniscus, growth of AC was similar to HC throughout pregnancy, whereas in humans AC only reaches the level of HC close to term. Growth rate of FL was similar in humans and the two Pan species until near day 180 post-ovulation. After that, the Pan species FL growth slowed compared with human FL. The newly developed fetal growth curves of P. paniscus will assist in monitoring prenatal development and predicting birth dates of this highly endangered species. © 2010 Wiley-Liss, Inc.

The presence of Cryptosporidium oocysts in 20 zoo animals of the Xining Zoo, 16 farm yaks and 42 farm goats in Qinghai province, China was investigated by an immunofluorescence test (IFT). The species and/or genotypes were determined by nested polymerase chain reaction (PCR) and sequence analysis of a fragment of the small subunit (SSU) rRNA gene. Cryptosporidium oocysts were found in 16 zoo animals, 2 yaks, and 15 goats by IFT. The IFT positive samples were further investigated by PCR, and 16 of them were found to be positive by that method also. Sequence analysis of the PCR products derived from Cryptosporidium oocysts from Black leopard (Panthera pardus), Heijing He (Grus nigricollis), Barbary sheep (Ammotragus lervia), Takin (Budorcas taxicolor), Lesser panda (Ailurus fulgens), and White-eared pheasant (Crossoptilon crossoptilon) fecal samples matched that of Cryptosporidium parvum mouse genotype. Sequence analyses of other PCR products were consistent with cervine genotype Cryptosporidium from Ibex (Capra ibex), a novel Cryptosporidium genotype from a wild yak (Bos mutus), C. bovis-like genotype from one goat sample and also a novel Cryptosporidium genotype from one other separate goat sample. The present work reports the first data on Cryptosporidium infections in animals from the Qinghai province of mountainous central western China and the first findings of the 'cervine' genotype in Capra ibex, C. bovis-like genotype and the new Cryptosporidium spp. in farm goat and in wild yak.

Scientists are increasing their efforts to promote public engagement with their science, but the efficacy of the methods used is often not scientifically evaluated. Here, we designed, installed and evaluated the educational impact of interactive games on touchscreens at two primate research centres based in zoo environments. The games were designed to promote interest in and understanding of primates and comparative psychology, as a scaffold towards interest in science more generally and with the intention of targeting younger individuals (under 16's). We used systematic observational techniques and questionnaires to assess the impact of the games on zoo visitors. The games facilitated increased interest in psychology and science in zoo visitors, and changed the knowledge of visitors, through demonstration of learning about specific scientific findings nested within the games. The impact of such devices was greatest on younger individuals (under 16's) as they were significantly more likely to engage with the games. On the whole, therefore, this study demonstrates that interactive devices can be successful educational tools, and adds to the growing body of evidence that conducting research on public view in zoos can have a tangible impact on public engagement with science.

Disposal of animal manure without treatment can be harmful to the environment. In this study, samples of four zoo animal dungs and one horse dung were pre-composted in two ways: (a) traditional composting and (b) bokashi pre-composting for 1month, followed by vermicomposting for 3months. The permanence (PEf) and reproductive potential (RP) of Eisenia foetida as well as the quality of vermicompost were evaluated. The PEf values and RP index of E. foetida were higher for samples pre-composted using the traditional composting method (98.7-88% and 31.85-16.27%, respectively) followed by vermicomposting (92.7-72.7% and 22.96-13.51%, respectively), when compared with those for bokashi pre-composted samples followed by vermicomposting, except for the horse dung sample (100% for both the parameters). The values of electrical conductivity (EC), cation exchange capacity (CEC), organic C, total N, available P, C/N ratio, and pH showed that both treatments achieved the norms of vermicompost (<4mScm -1 , 40cmolkg -1 , 20-50%, 1-4%, ≤20, 5.5-8.5, respectively). However, the maturity indices of vermicompost, namely, organic matter loss, N loss, and CEC/organic carbon (OC) ratio indicated that bokashi pre-composting followed by vermicomposting produced the highest values (98.7-70.7%, 97.67-96.65%, and 2.7-1.97%, respectively), when compared with the other method adapted in this study. Nevertheless, further studies with plants for plant growth evaluation are needed to assess the benefits and limitations of these two pre-composting methods prior to vermicomposting.

We present quantified visual morphologies of approximately 48 000 galaxies observed in three Hubble Space Telescope legacy fields by the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey (CANDELS) and classified by participants in the Galaxy Zoo project. 90 per cent of galaxies have z ≤ 3 and are observed in rest-frame optical wavelengths by CANDELS. Each galaxy received an average of 40 independent classifications, which we combine into detailed morphological information on galaxy features such as clumpiness, bar instabilities, spiral structure, and merger and tidal signatures. We apply a consensus-based classifier weighting method that preserves classifier independence while effectively down-weighting significantly outlying classifications. After analysing the effect of varying image depth on reported classifications, we also provide depth-corrected classifications which both preserve the information in the deepest observations and also enable the use of classifications at comparable depths across the full survey. Comparing the Galaxy Zoo classifications to previous classifications of the same galaxies shows very good agreement; for some applications, the high number of independent classifications provided by Galaxy Zoo provides an advantage in selecting galaxies with a particular morphological profile, while in others the combination of Galaxy Zoo with other classifications is a more promising approach than using any one method alone. We combine the Galaxy Zoo classifications of `smooth' galaxies with parametric morphologies to select a sample of featureless discs at 1 ≤ z ≤ 3, which may represent a dynamically warmer progenitor population to the settled disc galaxies seen at later epochs.

Dreamers, Poets, Citizens, and Scientists: Motivations for Engaging in GalaxyZoo Citizen Science

A particularly successful effort to engage the public in science has been to move the nearly countless galaxies imaged by the Sloan Digital Sky Survey to citizen scientists in a project known widely as Galaxy Zoo (URL; http://www.galaxyzoo.org). To everyone’s surprise, the unexpectedly large participation in the website has caused the data set, numbering over a million images, to be classified multiple times, quicker than the project leader anticipated, and continues to boast a high hit count on the website (15 classifications per second). Within 24 hours of launch, the site was receiving 70,000 classifications an hour, and more than 50 million classifications were received by the project during its first year, from almost 150,000 people. In a parallel effort, the Galaxy Zoo forum was created to handle the flood of emails that occurred alongside the flood of classifications, the team hoping that it would encourage the participants to handle each others' questions. By examining the motivations, methods and appeal of Galaxy Zoo to the participating public, other models of citizen science might be purposefully formulated to take advantage of the success exhibited in Galaxy Zoo. In addition, we want to understand the reasons people engage in science in informal settings in order to better enhance teaching methods in formal settings. Although in the past citizen science has primarily been used as a data collection method, there are many new opportunities contained in citizen science motivations and methods that we can use in future applications. This new and innovative method of online citizen science creates data for researchers of galaxies, but there is a parallel set of underlying data that has not yet been deeply analyzed: the motivations and underlying themes within the population of citizen scientists that could lead us to improve future citizen science projects. To address this, we pursued an investigation of the underlying reasons for the success of Galaxy Zoo

Zoos and aquariums aim to achieve lasting impact on their public audiences' awareness of biodiversity, its value, and the steps they can take to conserve it. Here, we evaluate the long-term educational impact of visits to zoos and aquariums on biodiversity understanding and knowledge of actions to help protect biodiversity. A minimum of two years after completing a repeated-measures survey before and after visiting a zoo or aquarium, the same participants were invited to take part in a follow-up online survey. Despite the small number of respondents (n = 161), our study may still represent the best available quantitative evidence pertaining to zoo and aquarium visits' long-term educational impact. We found that improvements in respondents' biodiversity understanding from pre- to post-visit leveled off, staying unchanged in the follow-up survey. In contrast, the improved knowledge of actions to help protect biodiversity from pre- to post-visit showed further improvement from post-visit to delayed post-visit follow-up survey. These results suggest that the immediate positive effects of a zoo or aquarium visit on biodiversity-related learning outcomes may be long lasting and even help lay the groundwork for further improvements over an extended period of time following the visit. © 2017 Wiley Periodicals, Inc.

Introductions of sable antelope (Hippotragus niger) can be difficult due to the potential ensuing aggression compounded by their large horns. The goal was to use hormonal assays and behavioral analyses to evaluate the success of an introduction of 2 adult females at Lincoln Park Zoo. The objectives were to (a) document behavioral and hormonal changes in 2 female sable antelope during the introduction, (b) compare fecal glucocorticoid metabolites (FGM) in each individual during the introduction stages, (c) measure fecal androgen metabolites (FAM) during introduction and compare with dominance rank and observed aggression, and (d) monitor estrous cycle synchronization. Results demonstrate that FGM were higher before than during and after the introduction. Behavioral observations indicated limited aggression between females, although the keeper survey results revealed that the new female was more dominant and had higher mean FGM and FAM than the resident. Both sable antelope were reproductively active throughout the year. Results indicate that fecal hormone analysis can provide zoo management with valuable information to minimize the risk of aggression, injury, and stress during introductions of nonhuman animals.

Adolescent Learning in the Zoo: Embedding a Non-Formal Learning Environment to Teach Formal Aspects of Vertebrate Biology

2012-06-01

The aim of this study was to assess the outcome of a zoo visit in terms of learning and retention of knowledge concerning the adaptations and behavior of vertebrate species. Basis of the work was the concept of implementing zoo visits as an out-of-school setting for formal, curriculum based learning. Our theoretical framework centers on the self-determination theory, therefore, we used a group-based, hands-on learning environment. To address this questions, we used a treatment—control design (BACI) with different treatments and a control group. Pre-, post- and retention tests were applied. All treatments led to a substantial increase of learning and retention knowledge compared to the control group. Immediately after the zoo visit, the zoo-guide tour provided the highest scores, while after a delay of 6 weeks, the learner-centered environment combined with a teacher-guided summarizing scored best. We suggest incorporating the zoo as an out-of-school environment into formal school learning, and we propose different methods to improve learning in zoo settings.

Visitor reaction to pacing behavior: influence on the perception of animal care and interest in supporting zoological institutions.

PubMed

Miller, Lance J

2012-01-01

Many publications within the field of zoo animal welfare have stated the importance of decreasing stereotypic behavior (e.g., pacing) to help ensure a positive visitor experience. The idea behind these statements is that visitors want to see animals engaged in natural behavior. Additionally, it is thought that watching an animal exhibit species-appropriate behavior could help increase a visitor's connection to wildlife and ultimately their interest in conservation. However, until recently, no information was available to validate such statements. The purpose of this research was to examine people's reaction to viewing an animal engaged in pacing behavior. Participants were randomly selected to fill out a survey after watching a short video of either a tiger pacing or resting (control). Results indicate that having viewed a tiger pacing significantly decreases people's perception of the level of care animals receive at that facility. In addition, people's interest in supporting zoos decreased as a result of viewing this behavior. Results are discussed from an animal welfare, business, and conservation perspective. © 2011 Wiley Periodicals, Inc.

A high prevalence of larval Echinococcus multilocularis (Em) infection was found in zoo primates in Hokkaido, Japan. In October 1997, a Japanese monkey (Macaca fuscata) died and histopathologically diagnosed as alveolar hydatidosis. Serum samples were collected from the remaining Japanese monkeys and examined for antibodies against Em by enzyme-linked immunosorbent assay and western blotting. Serological tests showed 12 more animals of the remaining 57 monkeys were possibly infected. Ultrasonography revealed that nine of these 12 animals had a cystic lesion in the liver. The band patterns of western blotting in the monkeys were very similar to those in human.

Changes in biogas production due to different ratios of some animal and agricultural wastes.

2001-03-01

The biogas production and some biochemical parameters of anaerobic fermentation at 30 degrees C for 40 days were studied for eight experimental groups of fermentation media, as affected by two factors: (1) the type of the animal waste (sheep waste, S and goat waste, G), and (2) the ratio of waste to olive cake which constitutes four levels (100:0 for S1 and G1; 80:20 for S2 and G2; 60:40 for S3 and G3 and 40:60 for S4 and G4). The results indicated that there was a significant decrease (P < 0.05) in the biogas production with an increase in the proportion of olive cake in place of animal waste. However, there was a significant increase in the biogas production for the S4 treatment compared with G4, reflecting an effect induced by the type of animal waste. The biogas production amounted to (l/kg VS/40 d): 62 (S1), 53 (S2), 49 (S3), 40 (S4), 58 (G1), 50 (G2), 44 (G3) and 25 (G4). The reduction in total solid (TS) weight, volatile solids (VS), neutral-detergent fiber decreased significantly (P < 0.05) with the increase in olive cake proportion in the digester. The reductions in VS were (% in DM): 58.2 (S1), 37.8 (S2), 26.6 (S3), 22.6 (S4), 58.1 (G1), 36 (G2), 33.4 (G3), 14.4 (G4). The rates of energy consumption were (MJ/kg DM/40 d): 15.36 (S1), 10.12 (S2), 7.84 (S3), 6.68 (S4), 14.16 (G1), 9.68 (G2), 8.41 (G3), 3.29 (G4).

Norway rats (Rattus norvegicus) are zoonotic reservoirs for Leptospira spp. and Toxoplasma gondii, and influence diseases in urban areas. Free-ranging and laboratory-raised rats from two zoos in southern Brazil were tested for Leptospira spp. and T. gondii using microscopic agglutination and modified agglutination tests, respectively. Overall, 25.6% and 4.6% free-ranging rats tested positive for Leptospira spp. and T. gondii, respectively, with co-seropositivity occurring in two animals. For laboratory-raised rats, 20% tested positive for Leptospira spp. Also, Leptospira biflexa serovar Patoc and Leptospira noguchii serovar Panama were found. Serosurveys can show the environmental prevalence of zoonotic pathogens.

The naked mole rat, Heterocephalus glaber, is a highly unusual mammal that displays a complex social system similar to that found in eusocial insects. Colonies of H. glaber are commonly maintained in zoo collections because they represent fascinating educational exhibits for the public. However, little is known about the genetic structure or sex ratio of captive populations of H. glaber. In this study, we developed a set of microsatellite markers to examine genetic variation in three captive zoo populations of H. glaber. We also studied sex ratio of these captive populations. Our goal was to determine levels of genetic variation within, and genetic differences between, captive populations of H. glaber. Overall, we found modest levels of genetic variation in zoo populations. We also uncovered little evidence for inbreeding within the captive populations. However, zoo populations did differ genetically, which may reflect the isolation of captive naked mole rat colonies. Finally, we found no evidence of biased sex ratios within colonies. Overall, our study documents levels of genetic variation and sex ratios in a captive eusocial mammalian population. Our results may provide insight into how to manage captive populations of H. glaber. © 2018 Wiley Periodicals, Inc.

The conditions in densely populated Bangladesh favor picornavirus transmission, resulting in a high rate of infection in the human population. Data suggest that nonhuman primates (NHP) may play a role in the maintenance and transmission of diverse picornaviruses in Bangladesh. At the Dhaka Zoo, multiple NHP species are caged in close proximity. Their proximity to other species and to humans, both zoo workers and visitors, provides the potential for cross-species transmission. To investigate possible interspecies and intraspecies transmission of picornaviruses among NHP, we collected fecal specimens from nine NHP taxa at the Dhaka Zoo at three time points, August 2007, January 2008, and June 2008. Specimens were screened using real-time PCR for the genera Enterovirus, Parechovirus, and Sapelovirus, and positive samples were typed by VP1 sequencing. Fifty-two picornaviruses comprising 10 distinct serotypes were detected in 83 fecal samples. Four of these serotypes, simian virus 19 (SV19), baboon enterovirus (BaEV), enterovirus 112 (EV112), and EV115, have been solely associated with infection in NHP. EV112, EV115, and SV19 accounted for 88% of all picornaviruses detected. Over 80% of samples from cages housing rhesus macaques, olive baboons, or hamadryas baboons were positive for a picornavirus, while no picornaviruses were detected in samples from capped langurs or vervet monkeys. In contrast to our findings among synanthropic NHP in Bangladesh where 100% of the picornaviruses detected were of human serotypes, in the zoo population, only 15% of picornaviruses detected in NHP were of human origin. Specific serotypes tended to persist over time, suggesting either persistent infection of individuals or cycles of reinfection.

Four of these serotypes, simian virus 19 (SV19), baboon enterovirus (BaEV), enterovirus 112 (EV112), and EV115, have been solely associated with infection in NHP. EV112, EV115, and SV19 accounted for 88% of all picornaviruses detected. Over 80% of samples from cages housing rhesus macaques, olive baboons, or hamadryas baboons were positive for a picornavirus, while no picornaviruses were detected in samples from capped langurs or vervet monkeys. In contrast to our findings among synanthropic NHP in Bangladesh where 100% of the picornaviruses detected were of human serotypes, in the zoo population, only 15% of picornaviruses detected in NHP were of human origin. Specific serotypes tended to persist over time, suggesting either persistent infection of individuals or cycles of reinfection. PMID:23097447

Adequate levels of dietary vitamin C are necessary for capybaras (Hydrochoerus hydrocharis) because they cannot synthesize the vitamin endogenously. Beginning in 2013, hair and weight loss, as well as general dermatitis, were observed in all individual capybaras (n = 4) in a mixed exhibit at Seoul Zoo. Seven additional vegetables, leafy greens, and fruits that increased dietary vitamin C concentration from ∼300-400 to >600 mg/kg dry matter were added to the diet since January 2015. Within 6 months, capybaras' skin and coats improved considerably, with hair becoming thicker and glossier. Animals visually appeared healthier and gained weight. In conclusion, hair loss, dermatitis, and weight loss in capybara can be improved by feeding enough fresh green leaves, vegetables, and fruits. Although vitamin C is considered a major factor for alleviation of poor body condition observed, increased status of other nutrients (i.e., vitamin B 6 ) provided by the diet change may also have contributed to the improvements seen in the capybara.

Equine herpesvirus type 1 (EHV-1) causes respiratory disorders and abortion in equids while EHV-1 regularly causes equine herpesvirus myeloencephalopathy (EHM), a stroke-like syndrome following endothelial cell infection in horses. Both EHV-1 and EHV-9 infections of non-definitive hosts often result in neuronal infection and high case fatality rates. Hence, EHV-1 and EHV-9 are somewhat unusual herpesviruses and lack strict host specificity, and the true extent of their host ranges have remained unclear. In order to determine the seroprevalence of EHV-1 and EHV-9, a sensitive and specific peptide-based ELISA was developed and applied to 428 sera from captive and wild animals representing 30 species in 12 families and five orders. Members of the Equidae, Rhinocerotidae and Bovidae were serologically positive for EHV-1 and EHV-9. The prevalence of EHV-1 in the sampled wild zebra populations was significantly higher than in zoos suggesting captivity may reduce exposure to EHV-1. Furthermore, the seroprevalence for EHV-1 was significantly higher than for EHV-9 in zebras. In contrast, EHV-9 antibody prevalence was high in captive and wild African rhinoceros species suggesting that they may serve as a reservoir or natural host for EHV-9. Thus, EHV-1 and EHV-9 have a broad host range favoring African herbivores and may have acquired novel natural hosts in ecosystems where wild equids are common and are in close contact with other perissodactyls.

2018-05-01

The effects of visitor presence on zoo and aquarium animals have become increasingly well studied, using measures such as behavioral responses and exhibit usage. Many taxa remain underrepresented in this literature; this is the case for marine mammals, despite widespread public concern for their welfare in managed care settings. The current study therefore used behavioral activity budgets and exhibit usage to assess the responses of California sea lions (Zalophus californianus) and harbor seals (Phoca vitulina) to visitors at the Seal Cove exhibit at Six Flags Discovery Kingdom, Vallejo CA. Data was collected via focal follow video recordings over the summer season of 2016, and analyzed using MANCOVAs, discriminant analyses, and modified Spread of Participation Indices. The sea lions showed no significant changes in behavior when visitors were present, but did show greater preference for the water bordering visitor viewing areas during these times. Two sea lions gave birth during the study period, and showed greater preference for land areas both adjacent to and out of sight of visitors when nursing compared to while pregnant. In contrast, the harbor seals showed significant behavioral changes in the presence of visitors, including increased vigilance and feeding. This was associated with increased preferential use of water areas adjacent to the visitor viewing area. Visitors were able to purchase fish to throw to the animals, which likely contributed to the differences observed. Overall, this study found little evidence for negative visitor impacts on two pinniped species in a zoo setting. © 2018 Wiley Periodicals, Inc.

Male-specific bacteriophage (MSB) densities were determined in animal and human fecal wastes to assess their potential impact on aquatic environments. Fecal samples (1,031) from cattle, chickens, dairy cows, dogs, ducks, geese, goats, hogs, horses, seagulls, sheep, and humans as well as 64 sewerage samples were examined for MSB. All animal species were found to harbor MSB, although the great majority excreted these viruses at very low levels. The results from this study demonstrate that in areas affected by both human and animal wastes, wastewater treatment plants are the principal contributors of MSB to fresh, estuarine, and marine waters.

Laboratory animal research published in plastic surgery journals in 2014 has extensive waste: A systematic review.

PubMed

Freshwater, M Felix

2015-11-01

Laboratory animal research must be designed in a manner that minimizes bias if it is to yield valid and reproducible results. In 2009, a survey that examined 271 animal studies found that 87% did not use randomization and 86% did not use blinding. This has been called "research waste" because it wasted time and resources. This systematic review measured the quantity of research waste in plastic surgery journals in 2014. The PRISMA-P protocol was used. SCOPUS and PubMed searches were done for all animal studies published in 2014 in Aesthetic Plast Surg, Aesthet Surg J, Ann Plast Surg, JPRAS, J Plast Surg Hand Surg and Plast Reconstr Surg. These were supplemented by manual searches of the 2014 issues not indexed. Articles were analyzed for descriptions of randomization, randomization methodology, allocation concealment, and blinding of the primary outcome assessment. Corresponding authors who mentioned randomization without elaborating were emailed for details. 112 of 154 articles met the inclusion criteria. Only 24/112 (21.4%) had blinding of the primary outcome measure, 28/110 (25.5%) of articles that required randomization mentioned it. While 12/28 articles clearly described randomizing the intervention, only 4/28 described the method of randomization, and 2/28 mentioned allocation concealment. Only two authors responded and described the randomization methodology. The quality of plastic surgery laboratory animal research published in 2014 was poor. Use of the National Centre for the Replacement Refinement & Reduction of Animals in Research's "Animal Research: Reporting In Vivo Experiments" (ARRIVE) Guidelines by authors, and enforcement of them by editors and reviewers could improve research quality and reduce waste.

OBJECTIVE To determine the incidence of and risk factors for clinical feline herpesvirus (FHV) infection in zoo-housed cheetahs and determine whether dam infection was associated with offspring infection. DESIGN Retrospective cohort study. ANIMALS 144 cheetah cubs born in 6 zoos from 1988 through 2007. PROCEDURES Data were extracted from the health records of cheetahs and their dams to identify incident cases of clinical FHV infection and estimate incidence from birth to 18 months of age. Univariate and multivariable Cox proportional hazards models, controlling for correlations among cheetahs with the same dam, were used to identify risk factors for incident FHV infection. RESULTS Cumulative incidence of FHV infection in cheetah cubs was 35% (50/144). No significant association between dam and offspring infection was identified in any model. Factors identified as significant through multivariable analysis varied by age group. For cheetahs up to 3 months of age, the most important predictor of FHV infection was having a dam that had received a preparturition FHV vaccine regimen that included a modified-live virus vaccine versus a dam that had received no preparturition vaccine. Other risk factors included being from a small litter, being born to a primiparous dam, and male sex. CONCLUSIONS AND CLINICAL RELEVANCE This study provided the first population-level characterization of the incidence of and risk factors for FHV infection in cheetahs, and findings confirmed the importance of this disease. Recognition that clinical FHV infection in the dam was not a significant predictor of disease in cubs and identification of other significant factors have implications for disease management.

Urban animals and birds in particular are able to cope with diverse novel threats in a city environment such as avoiding novel, unfamiliar predators. Predator avoidance often includes alarm signals that can be used also by hetero-specifics, which is mainly the case in mixed-species flocks. It can also occur when species do not form flocks but co-occur together. In this study we tested whether urban crows use alarm calls of conspecifics and hetero-specifics (jackdaws, Corvus monedula) differently in a predator and a non-predator context with partly novel and unfamiliar zoo animal species. Birds were tested at the Tiergarten Schönbrunn in the city of Vienna by playing back con- and hetero-specific alarm calls and control stimuli (great tit song and no stimuli) at predator (wolf, polar bear) and non-predator (eland antelope and cranes, peccaries) enclosures. We recorded responses of crows as the percentage of birds flying away after hearing the playback (out of those present before the playback) and as the number of vocalizations given by the present birds. A significantly higher percentage of crows flew away after hearing either con- or hetero-specific alarm calls, but it did not significantly differ between the predator and the non-predator context. Crows treated jackdaw calls just as crow calls, indicating that they make proper use of hetero-specific alarm calls. Responding similarly in both contexts may suggest that the crows were uncertain about the threat a particular zoo animal represents and were generally cautious. In the predator context, however, a high percentage of crows also flew away upon hearing the great tit control song which suggests that they may still evaluate those species which occasionally killed crows as more dangerous and respond to any conspicuous sound.

The Amur leopard is at the point of extinction. At present there are fewer than 35 in the wild. Their natural habitat ranges from China to the North Korean peninsula to Primorsky Krai in Russia. A reintroduction plan has been proposed to increase the population in the wild; however, this proposed plan still has many questions to be answered as to how effective it will be. The main objective is to reintroduce animals from a select group within the Far Eastern leopard programme or the Species Survival programme, which consist of leopards from select populations in the Northern Hemisphere. Zoos are central to the success of this plan, providing suitable breeding pairs to breed animals for reintroduction and also raising much needed funds to finance the project. Zoos are also central in educating the public about the critical status of the Amur leopard and other endangered animals of the world. Veterinary surgeons, by the very nature of their professional skills, are at the forefront of this seemingly endless battle against extinction of thousands of species that are critical to maintaining the balance of our fragile ecosystem. Veterinarians can analyze the health risks and health implications of reintroduction on the animals to be reintroduced and also on the native population. A world without large cats is a world hard to imagine. If we look closer at the implications of extinction, we see the domino effect of their loss and an ecosystem out of control. © 2013 Published by Elsevier Inc.

Stereotypic behavior is an important indicator of compromised welfare. Zoo elephants are documented to perform stereotypic behavior, but the factors that contribute to performance have not been systematically assessed. We collected behavioral data on 89 elephants (47 African [Loxodonta africana], 42 Asian [Elephas maximus]) at 39 North American zoos during the summer and winter. Elephants were videoed for a median of 12 daytime hours per season. A subset of 32 elephants (19 African, 13 Asian) was also observed live for a median of 10.5 nighttime hours. Percentages of visible behavior scans were calculated from five minute instantaneous samples. Stereotypic behavior was the second most commonly performed behavior (after feeding), making up 15.5% of observations during the daytime and 24.8% at nighttime. Negative binomial regression models fitted with generalized estimating equations were used to determine which social, housing, management, life history, and demographic variables were associated with daytime and nighttime stereotypic behavior rates. Species was a significant risk factor in both models, with Asian elephants at greater risk (daytime: p<0.001, Risk Ratio = 4.087; nighttime: p<0.001, Risk Ratio = 8.015). For both species, spending time housed separately (p<0.001, Risk Ratio = 1.009), and having experienced inter-zoo transfers (p<0.001, Risk Ratio = 1.175), increased the risk of performing higher rates of stereotypy during the day, while spending more time with juvenile elephants (p<0.001, Risk Ratio = 0.985), and engaging with zoo staff reduced this risk (p = 0.018, Risk Ratio = 0.988). At night, spending more time in environments with both indoor and outdoor areas (p = 0.013, Risk Ratio = 0.987) and in larger social groups (p = 0.039, Risk Ratio = 0.752) corresponded with reduced risk of performing higher rates of stereotypy, while having experienced inter-zoo transfers (p = 0.033, Risk Ratio = 1.115) increased this risk.

Early-life exposures and Johne's disease risk in zoo ruminants.

PubMed

Burgess, Tristan L; Witte, Carmel L; Rideout, Bruce A

2018-01-01

Johne's disease, caused by Mycobacterium avium subsp. paratuberculosis (MAP), is a chronic, progressive bacterial enteritis of ruminants that can cause serious losses in both livestock and exotic species. Infection risk in exotic ruminants is associated with maternal infection status, but the effect of other herdmates on risk of infection has not been reported, to our knowledge. We conducted a retrospective cohort study to evaluate the association between MAP infection status and early-life contact with infected herdmates. The study population included 3,234 individuals representing 128 species at San Diego Zoo Global facilities between 1991 and 2010. Animal movement, health, and pathology records were used to trace enclosure-sharing contacts between members of the study population and any MAP-infected animal. Contact-days were counted by age of the reference animal and the number of unique infected individuals contacted. Herdmate infection status was stratified by stage of infection (180 d prior to diagnosis), age, and whether relevant lesions were found at autopsy. Having an infected herdmate was a strong risk factor for infection (OR = 4.4; 95% CI: 1.9-10.3), and each method of defining herdmate infection status showed significant differences in infection risk. The best predictor was number of contact-days within the first week of life, with a 2-fold increase in risk associated with each doubling in the number of contact-days (OR = 2.1; 95% CI: 1.1-4.0). We conclude that early contact with infected animals is an important predictor of MAP infection risk, although the effect size is smaller than that previously described for maternal infection status.

Genealogical records of animals (studbook) are created to avoid reproduction between closely related individuals, which could cause inbreeding, particularly for such endangered species as the Panthera onca (Linnaeus, 1758). Jaguar is the largest felid in the Americas and is considered an important ecological key species. In Mexico, wild jaguar populations have been significantly reduced in recent decades, and population decline typically accompany decreases in genetic variation. There is no current census of captive jaguars in Mexico, and zoos do not follow a standardized protocol in breeding programs based on genetic studies. Here, we emphasise the importance of maintaining an adequate level of genetic variation and propose the implementation of standardised studbooks for jaguars in Mexico, mainly to avoid inbreeding. In addition, achieving the aims of studbook registration would provide a population genetic characterisation that could serve as a basis for ex situ conservation programmes.

Toxoplasmosis, caused by the protozoan Toxoplasma gondii, is one of the most widespread zoonoses in the world. It can affect most warm-blooded animals but only felids are its definitive hosts. We determined seroprevalence and associated risk factors in birds and mammals kept in two zoological parks in northern Portugal. Sera from 77 birds and 42 mammals were assayed for the presence of T. gondii antibodies by the modified agglutination test (MAT, cut-off titre 20); 34.5% (41/119) were seropositive. All seropositive animals were apparently healthy except one seropostive mandarin (Aix galericulata) which had chorioretinitis. This is the first report on T. gondii seroprevalence in wild animals in captivity in Portugal. The present findings indicate a widespread exposure of zoo animals in Portugal to T. gondii.

Callitrichid hepatitis (CH) is an acute, frequently fatal viral hepatitis which affects members of the primate family Callitrichidae (R. J. Montali, E. C. Ramsay, C. B. Stephensen, M. Worley, J. A. Davis, and K. V. Holmes, J. Infect. Dis. 160:759-765, 1989; E. C. Ramsay, R. J. Montali, M. Worley, C. B. Stephensen, and K. V. Holmes, J. Zoo Wildlife Med. 20:178-183, 1989). Outbreaks of the disease occur in zoos and animal parks. In this study, CH-specific antigens were identified in the livers of infected animals by using immune sera from primates with CH and CH-exposed asymptomatic animals. Three CH-specific antigens with apparent molecular masses of 34, 54, and 65 kDa were identified. A polyclonal antiserum was raised against the 54-kDa antigen. These antigens were not found in the livers of uninfected animals and may be viral proteins. Our results suggest that at least five of the six outbreaks of CH considered here were caused by the same virus or by an antigenically related virus. Images PMID:2123012

The Neutron Star Zoo

Neutron stars are a very diverse population, both in their observational and their physical properties. They prefer to radiate most of their energy at X-ray and gamma-ray wavelengths. But whether their emission is powered by rotation, accretion, heat, magnetic fields or nuclear reactions, they are all different species of the same animal whose magnetic field evolution and interior composition remain a mystery. This article will broadly review the properties of inhabitants of the neutron star zoo, with emphasis on their high-energy emission. XXX Neutron stars are found in a wide variety of sources, displaying an amazing array of behavior. They can be isolated or in binary systems, accreting, heating, cooling, spinning down, spinning up, pulsing, flaring and bursting. The one property that seems to determine their behavior most strongly is their magnetic field strength, structure and evolution. The hot polar caps, bursts and flares of magnetars are likely due to the rapid decay and twisting of their superstrong magnetic fields, whose very existence requires some kind of early dynamo activity. The intermediate-strength magnetic fields of RPPs determines their spin-down behavior and radiation properties. However, the overlap of the magnetar and RPP populations is not understood at present. Why don't high-field RPPs burst or flare? Why don't lower-field magnetars sometimes behave more like RPPs? INS may be old magnetars whose high fields have decayed, but they do not account for the existence of younger RPPs with magnetar-strength fields. Not only the strength of the magnetic field but also its configuration may be important in making a NS a magnetar or a RPP. Magnetic field decay is a critical link between other NS populations as well. "Decay" of the magnetic field is necessary for normal RPPs to evolve into MSPs through accretion and spin up in LMXBs. Some kind of accretion-driven field reduction is the most likely mechanism, but it is controversial since it is not

As part of a health investigation on koalas at San Diego Zoo, serum samples were analyzed from 18 free-ranging and 22 zoo-based koalas, Phascolarctos cinereus. Serum concentrations of calcium, chloride, cobalt, copper, iron, magnesium, manganese, molybdenum, phosphorus, potassium, selenium, sodium, zinc, and vitamins A, E, and 25(OH)D3 were quantified. Calcium, chloride, molybdenum, selenium, and vitamin E concentrations were significantly higher in zoo-based koalas than in free-ranging koalas, whereas magnesium, manganese, phosphorus, and zinc concentrations were significantly higher in the free-ranging koalas. No significant differences were found between genders. The results from this study will help to establish a starting point for determining target circulating nutrient concentrations in koalas.

Expansion and intensification of large-scale animal feeding operations (AFOs) in the United States has resulted in concern about environmental contamination and its potential public health impacts. The objective of this investigation was to obtain background data on a broad profile of antimicrobial residues in animal wastes and surface water and groundwater proximal to large-scale swine and poultry operations. The samples were measured for antimicrobial compounds using both radioimmunoassay and liquid chromatography/electrospray ionization-mass spectrometry (LC/ESI-MS) techniques. Multiple classes of antimicrobial compounds (commonly at concentrations of >100 μg/l) were detected in swine waste storage lagoons. In addition, multiple classes of antimicrobial compounds were detected in surface and groundwater samples collected proximal to the swine and poultry farms. This information indicates that animal waste used as fertilizer for crops may serve as a source of antimicrobial residues for the environment. Further research is required to determine if the levels of antimicrobials detected in this study are of consequence to human and/or environmental ecosystems. A comparison of the radioimmunoassay and LC/ESI-MS analytical methods documented that radioimmunoassay techniques were only appropriate for measuring residues in animal waste samples likely to contain high levels of antimicrobials. More sensitive LC/ESI-MS techniques are required in environmental samples, where low levels of antimicrobial residues are more likely.

The personality trait of curiosity has been shown to increase welfare in humans. If this positive welfare effect is also true for non-humans, animals with high levels of curiosity may be able to cope better with stressful situations than their conspecifics. Before discoveries can be made regarding the effect of curiosity on an animal's ability to cope in their environment, a way of measuring curiosity across species in different environments must be created to standardise testing. To determine the suitability of novel objects in testing curiosity, species from different evolutionary backgrounds with sufficient sample sizes were chosen. Barbary sheep ( Ammotragus lervia) n  = 12, little penguins ( Eudyptula minor) n  = 10, ringtail lemurs ( Lemur catta) n  = 8 , red tailed black cockatoos ( Calyptorhynchus banksia) n  = 7, Indian star tortoises ( Geochelone elegans) n  = 5 and red kangaroos ( Macropus rufus) n  = 5 were presented with a stationary object, a moving object and a mirror. Having objects with different characteristics increased the likelihood individuals would find at least one motivating. Conspecifics were all assessed simultaneously for time to first orientate towards object (s), latency to make contact (s), frequency of interactions, and total duration of interaction (s). Differences in curiosity were recorded in four of the six species; the Barbary sheep and red tailed black cockatoos did not interact with the novel objects suggesting either a low level of curiosity or that the objects were not motivating for these animals. Variation in curiosity was seen between and within species in terms of which objects they interacted with and how long they spent with the objects. This was determined by the speed in which they interacted, and the duration of interest. By using the measure of curiosity towards novel objects with varying characteristics across a range of zoo species, we can see evidence of evolutionary, husbandry and individual

2017-06-01

A retrospective study was conducted to review neoplasia of captive snakes in the Zoo Atlanta collection from 1992 to 2012. Of 255 snakes that underwent necropsy and histopathologic examination at Zoo Atlanta during the study period, 37 were observed with neoplasia at necropsy. In those 37 snakes, 42 neoplastic lesions of 18 primary cell types were diagnosed. Thirty-five of those neoplasms (83.3%) were malignant, and of those, 19 were of mesenchymal origin, whereas 14 were of epithelial origin. The median annual rate of neoplasia at necropsy was 12.5% (interquartile range = 2.8-19.5%) over the 21-yr study period. The mean estimated age at death for snakes with neoplasia was 13.2 yr (range, 1-24 yr). Investigating the incidence and clinical significance of neoplasia in captive snakes is vital for developing effective preventative and treatment regimes.

Numerous studies addressed the diversity of bird Plasmodium and Haemoproteus parasites. However, a few have been carried out in continental avian hotspot regions such as Brazil, a country with markedly different biomes, including Amazon, Brazilian Savanna, Atlantic Forest, Caatinga, Pantanal, and Pampas. We present the first study on hemosporidian (Haemosporida) parasites in free-living birds from an Atlantic Forest fragment where more than 80 avian species have been reported. Within this area, the São Paulo Zoo locates, and it is the fourth largest zoo in the world and the largest in Latin America. A total of 133 free-living bird samples representing 12 species were collected in the zoo, with the overall hemosporidian prevalence of 18 % by PCR-based diagnostics. Twenty-four positive PCR signals were reported from four different bird species, including migratory ones. Columba livia, an urban species, considered nowadays a pest in big cities, showed 100 % prevalence of Haemoproteus spp., mainly Haemoproteus columbae. We discuss the epidemiological importance of new parasites introduced by migratory birds in the São Paulo Zoo area and the risk it poses to the captive species, which are natives or exotics. We also warn about the influence these parasites can have on the biodiversity and the structure of host populations by altering the competitive interaction between the free-living and the captive birds.

Microbiological Safety of Animal Wastes Processed by Physical Heat Treatment: An Alternative To Eliminate Human Pathogens in Biological Soil Amendments as Recommended by the Food Safety Modernization Act.

PubMed

Chen, Zhao; Jiang, Xiuping

2017-03-01

Animal wastes have high nutritional value as biological soil amendments of animal origin for plant cultivation in sustainable agriculture; however, they can be sources of some human pathogens. Although composting is an effective way to reduce pathogen levels in animal wastes, pathogens may still survive under certain conditions and persist in the composted products, which potentially could lead to fresh produce contamination. According to the U.S. Food and Drug Administration Food Safety Modernization Act, alternative treatments are recommended for reducing or eliminating human pathogens in raw animal manure. Physical heat treatments can be considered an effective method to inactivate pathogens in animal wastes. However, microbial inactivation in animal wastes can be affected by many factors, such as composition of animal wastes, type and physiological stage of the tested microorganism, and heat source. Following some current processing guidelines for physical heat treatments may not be adequate for completely eliminating pathogens from animal wastes. Therefore, this article primarily reviews the microbiological safety and economic value of physically heat-treated animal wastes as biological soil amendments.

Rates of inbreeding and genetic adaptation for populations managed as herds in zoos with a rotational mating system or with optimized contribution of parents.

PubMed

Mucha, S; Komen, H

2016-08-01

This study compares two genetic management scenarios for species kept in herds, such as deer. The simulations were designed so that their results can be extended to a wide range of zoo populations. In the first scenario, the simulated populations of size 3 × 20, 6 × 40 or 20 × 60 (herds × animals in herd) were managed with a rotational mating (RM) scheme in which 10%, 20% or 50% of males were selected for breeding and moved between herds in a circular fashion. The second scenario was based on optimal contribution theory (OC). OC requires an accurate pedigree to calculate kinship; males were selected and assigned numbers of offspring to minimize kinship in the next generation. RM was efficient in restriction of inbreeding and produced results comparable with OC. However, RM can result in genetic adaptation of the population to the zoo environment, in particular when 20% or less males are selected for rotation and selection of animals is not random. Lowest rates of inbreeding were obtained by combining OC with rotation of males as in the RM scheme. RM is easy to implement in practice and does not require pedigree data. When full pedigree is available, OC management is preferable. © 2015 Blackwell Verlag GmbH.

It is common for biomechanics data sets to contain numerous dependent variables recorded over time, for many subjects, groups, and/or conditions. These data often require standard sorting, processing, and analysis operations to be performed in order to answer research questions. Visualization of these data is also crucial. This manuscript presents biomechZoo, an open-source toolbox that provides tools and graphical user interfaces to help users achieve these goals. The aims of this manuscript are to (1) introduce the main features of the toolbox, including a virtual three-dimensional environment to animate motion data (Director), a data plotting suite (Ensembler), and functions for the computation of three-dimensional lower-limb joint angles, moments, and power and (2) compare these computations to those of an existing validated system. To these ends, the steps required to process and analyze a sample data set via the toolbox are outlined. The data set comprises three-dimensional marker, ground reaction force (GRF), joint kinematic, and joint kinetic data of subjects performing straight walking and 90° turning manoeuvres. Joint kinematics and kinetics processed within the toolbox were found to be similar to outputs from a commercial system. The biomechZoo toolbox represents the work of several years and multiple contributors to provide a flexible platform to examine time-series data sets typical in the movement sciences. The toolbox has previously been used to process and analyse walking, running, and ice hockey data sets, and can integrate existing routines, such as the KineMat toolbox, for additional analyses. The toolbox can help researchers and clinicians new to programming or biomechanics to process and analyze their data through a customizable workflow, while advanced users are encouraged to contribute additional functionality to the project. Students may benefit from using biomechZoo as a learning and research tool. It is hoped that the toolbox can play a

Inquiry-based activities that utilize the Cool Cosmos image galleries have been designed and developed by K12 teachers enrolled in The Invisible Universe Online for Teachers course. The exploration activities integrate the Our Infrared World Gallery (http://coolcosmos.ipac.caltech.edu/image_galleries/our_ir_world_gallery.html) with either the Infrared Zoo gallery (http://coolcosmos.ipac.caltech.edu/image_galleries/ir_zoo/index.html) or the Infrared Yellowstone image http://coolcosmos.ipac.caltech.edu/image_galleries/ir_yellowstone/index.html) and video (http://coolcosmos.ipac.caltech.edu/videos/ir_yellowstone/index.html) galleries. Complete instructor guides have been developed for the activities and will be presented by the authors in poster and CD form. Although the activities are written for middle and highschool learners, they can easily be adapted for college audiences. The Our Infrared World Gallery exploration helps learners think critically about visible light and infrared light as they compare sets of images (IR and visible light) of known objects. For example: by taking a regular photograph of a running faucet, can you tell if it is running hot or cold water? What new information does the IR image give you? The Infrared Zoo activities encourage learners to investigate the differences between warm and cold blooded animals by comparing sets of IR and visible images. In one activity, learners take on the role of a pit viper seeking prey in various desert and woodland settings. The main activities are extended into the real world by discussing and researching industrial, medical, and societal applications of infrared technologies. The Infrared Yellowstone lessons give learners a unique perspective on Yellowstone National Park and it's spectacular geologic and geothermal features. Infrared video technology is highlighted as learners make detailed observations about the visible and infrared views of the natural phenomena. The "Cool Cosmos" EPO activities are

Bats may be held captive in zoos and breeding programmes, and for rehabilitation due to illness, abandonment or injury. To describe the frequency and characteristics of skin disease in captive bats. Zoos (n = 164) in Europe, North America, Australia and New Zealand, Wildlife Disease Association members and rehabilitators were invited to complete online questionnaires on skin lesions and housing. Associations between lesion type and site, frequency, species, age, suspected cause and season, and their association with housing in zoos were tested using chi-squared and two-sample z-tests. Skin lesions were seen by 38.5% (15 of 39) of responding zoos and more frequently by rehabilitators (66.7%, 18 of 27; P = 0.024). Of the total of 153 lesions of any type reported by zoos and rehabilitators, almost two thirds occurred on the pinnae (49 of 153, 32%) or wing membranes (45 of 153, 29%). Amongst pinnal lesions, crusting (27%), swelling and redness (25%) and necrosis (20%) were most frequent. In zoos, pinnal (P = 0.001) and wing lesions (P = 0.045) were associated with "season", being more common in winter. Pruritus was rare but more often reported from rehabilitation centres (12 of 77 observed lesions) than from zoos (1 of 76) (P = 0.0015). Lesions most often affected adult and geriatric bats in zoos, and juveniles and adults in rehabilitation. Eight respondents reported that skin disease necessitated euthanasia in individual bats. There was no significant association between type of housing and lesions. Pinnal and wing lesions were common in captive bats, often with necrosis. Further research into the causes is needed to improve health and welfare of captive bats. © 2016 ESVD and ACVD.

Composting operations are a rich source for prospection of biomass degradation enzymes. We have analyzed the microbiomes of two composting samples collected in a facility inside the São Paulo Zoo Park, in Brazil. All organic waste produced in the park is processed in this facility, at a rate of four tons/day. Total DNA was extracted and sequenced with Roche/454 technology, generating about 3 million reads per sample. To our knowledge this work is the first report of a composting whole-microbial community using high-throughput sequencing and analysis. The phylogenetic profiles of the two microbiomes analyzed are quite different, with a clear dominance of members of the Lactobacillus genus in one of them. We found a general agreement of the distribution of functional categories in the Zoo compost metagenomes compared with seven selected public metagenomes of biomass deconstruction environments, indicating the potential for different bacterial communities to provide alternative mechanisms for the same functional purposes. Our results indicate that biomass degradation in this composting process, including deconstruction of recalcitrant lignocellulose, is fully performed by bacterial enzymes, most likely by members of the Clostridiales and Actinomycetales orders.

Characterizing abnormal behavior in a large population of zoo-housed chimpanzees: prevalence and potential influencing factors

PubMed Central

Jacobson, Sarah L.; Bloomsmith, Mollie A.

2016-01-01

Abnormal behaviors in captive animals are generally defined as behaviors that are atypical for the species and are often considered to be indicators of poor welfare. Although some abnormal behaviors have been empirically linked to conditions related to elevated stress and compromised welfare in primates, others have little or no evidence on which to base such a relationship. The objective of this study was to investigate a recent claim that abnormal behavior is endemic in the captive population by surveying a broad sample of chimpanzees (Pan troglodytes), while also considering factors associated with the origins of these behaviors. We surveyed animal care staff from 26 accredited zoos to assess the prevalence of abnormal behavior in a large sample of chimpanzees in the United States for which we had information on origin and rearing history. Our results demonstrated that 64% of this sample was reported to engage in some form of abnormal behavior in the past two years and 48% of chimpanzees engaged in abnormal behavior other than coprophagy. Logistic regression models were used to analyze the historical variables that best predicted the occurrence of all abnormal behavior, any abnormal behavior that was not coprophagy, and coprophagy. Rearing had opposing effects on the occurrence of coprophagy and the other abnormal behaviors such that mother-reared individuals were more likely to perform coprophagy, whereas non-mother-reared individuals were more likely to perform other abnormal behaviors. These results support the assertion that coprophagy may be classified separately when assessing abnormal behavior and the welfare of captive chimpanzees. This robust evaluation of the prevalence of abnormal behavior in our sample from the U.S. zoo population also demonstrates the importance of considering the contribution of historical variables to present behavior, in order to better understand the causes of these behaviors and any potential relationship to psychological

Haemochromatosis in a Brazilian tapir (Tapirus terrestris) in an Australian zoo.

A 23-year-old Brazilian, or lowland, tapir with a 6-month history of loss of body condition developed clinical signs and laboratory findings consistent with liver failure. The animal was euthanased and a diagnosis of hepatic haemochromatosis was made based on histopathology. Two other healthy tapirs in the same collection had chronically elevated serum and tissue iron concentrations. The excessive accumulation of iron in tissues with resultant tissue damage (i.e. haemochromatosis) has been reported in a range of captive species. This and other reported cases of haemochromatosis in the Brazilian tapir would suggest that this condition is an important consideration in the management of this species in zoos. Further research into the endogenous regulation of iron metabolism, especially the role of hepcidin, in tapirs and other species at risk of iron storage disorders may be helpful in the prevention of this condition. © 2012 The Authors.

A survey of abnormal repetitive behaviors in North American river otters housed in zoos.

PubMed

Morabito, Paige; Bashaw, Meredith J

2012-01-01

Stereotypic behaviors, indicating poor welfare and studied in a variety of species (especially carnivores), appear related to characteristics of current and past environments. Although North American river otters (Lontra canadensis) often develop abnormal, repetitive, possibly stereotypic behaviors, no published reports describe otter housing and management or characterize how these variables relate to abnormal repetitive behavior (ARB) occurrence. The first author developed surveys to gather data on housing, individual history, management, and the prevalence of ARBs in otters housed in facilities accredited by the Association of Zoos and Aquariums. Consistent with anecdotal evidence that otters are prone to ARBs, 46% of river otters in the study exhibit them. ARBs were mostly locomotor and often preceded feeding. Exhibits where otters were fed and trained housed a greater percentage of nonhuman animals with ARBs. This study supports the Tarou, Bloomsmith, and Maple (2005) report that more hands-on management is associated with higher levels of ARBs because management efforts are only for animals with ARBs. Escape motivation, breeding season, feeding cues, and ability to forage may affect ARBs in river otters and should be investigated.

Ratios of conservative chemicals have been used to identify sources of groundwater contamination. While chloride/bromide ratios have been reported for several common sources of groundwater contamination, little work has been done on leachate derived from farm-animal waste. In this study, chloride/bromide ratios were measured in leachate derived from longhorn-cattle, quarterhorse, and pygme-goat waste at a farm in Abilene, Texas, USA. (Minimum, median, and maximum) chloride/bromide ratios of (66.5, 85.6, and 167), (119, 146, and 156), and (35.4, 57.8, and 165) were observed for cattle, horses, and goats, respectively. These ratios are below typical values for domestic wastewater and within the range commonly observed for oilfield brine. Results of this study have important implications for identifying sources of contaminated groundwater in settings with significant livestock and/or oil production.

The Moon Zoo citizen science website launched in May 2010 and invited the public to annotate images from the Lunar Reconnaissance Orbiter's Narrow Angle Camera (NAC). Tasks included marking the edges of craters with an ellipse tool, indicating where linear features (e.g. scarps) and special types of craters (e.g. dark haloed) are located with a box, and rating the number of boulders in an image. The goal of this project is to create crater and feature catalogues for large areas of the moon. In addition to doing science, Moon Zoo also seeks to educate its audience through educational content, to engage them through social media, and to understand them through research into their motivations and behaviors.

2007-08-01

Enteric pathogens in animal waste that is not properly processed can contaminate the environment and food. The persistence of pathogens in animal waste depends upon the waste treatment technology, but little is known about persistence of porcine viruses. Our objectives were to characterize the porcine enteric viruses (porcine noroviruses [PoNoVs], porcine sapoviruses [PoSaVs], rotavirus A [RV-A], RV-B, and RV-C) in fresh feces or manure and to evaluate the effects of different candidate environmentally superior technologies (ESTs) for animal waste treatment on the detection of these viruses. Untreated manure and samples collected at different stages during and after treatment were obtained from swine farms that used conventional waste management (CWM) and five different candidate ESTs. The RNA from porcine enteric viruses was detected by reverse transcription-PCR and/or seminested PCR; PoSaV and RV-A were also detected by enzyme-linked immunosorbent assay. Cell culture immunofluorescence (CCIF) and experimental inoculation of gnotobiotic (Gn) pigs were used to determine RV-A/C infectivity in posttreatment samples. The PoSaV and RV-A were detected in pretreatment samples from each farm, whereas PoNoV and RV-C were detected in pretreatment feces from three of five and four of five farms using the candidate ESTs, respectively. After treatment, PoSaV RNA was detected only in the samples from the farm using CWM and not from the farms using the candidate ESTs. RV-A and RV-C RNAs were detected in four of five and three of four candidate ESTs, respectively, after treatment, but infectious particles were not detected by CCIF, nor were clinical signs or seroconversion detected in inoculated Gn pigs. These results indicate that only RV-A/C RNA, but no viral infectivity, was detected after treatment. Our findings address a public health concern regarding environmental quality surrounding swine production units.

Sustainable production of renewable fuels has become an imperative goal but also remains a huge challenge faced by the chemical industry. A variety of low-value, renewable sources of carbon such as wastes and by-products must be evaluated for their potential as feedstock to achieve this goal. Hydrogenation of blends comprising waste animal fat (≤70 wt%) and low-value fluid catalytic cracking light cycle oil (≥30 wt%), with a total aromatic content of 87.2 wt%, was studied on a commercial sulfided NiMo/Al 2 O 3 catalyst. The fuel fraction in the diesel boiling range was separated by fractional distillation from the organic liquid product obtained from the catalytic conversion of the blend of 70 wt% waste animal fat and 30 wt% light cycle oil. Diesel fuel of the best quality was obtained under the following reaction conditions: T = 615-635 K, P = 6 MPa, LHSV = 1.0 h -1 , H 2 /feedstock ratio = 600 Nm 3 /m 3 . The presence of fat in the feedstock was found to promote the conversion of light cycle oil to a paraffinic blending component for diesel fuel. Thus, a value-added alternative fuel with high biocontent can be obtained from low-value refinery stream and waste animal fat. The resultant disposal of waste animal fat, and the use of fuel containing less fossil carbon for combustion helps reduce the emission of pollutants. Copyright © 2018 Elsevier Ltd.

Many of the goals and performance objectives for elementary science deal with hands-on experiences such as observing the characteristics of living things, sorting and classifying, and measuring and recording data. Ideal environments for learning episodes that can foster these objectives are zoos and parks or nature preserves. This poster describes a program that uses the University faculty, local master elementary teachers, and Zoo staff and facilities to: (1) educate K-6 teachers about zoology, ecology, and evolution, (2) provide practical, on-site learning exercises as examples of how teachers can develop zoo visits that will be true learning experiences, (3) help themore » participants develop zoo-related exercises of classroom use, (4) show the participants the behind-the scenes work that goes on at a zoo, and (5) establish a close rapport between the teachers and a large group of professional resource persons. We present the results of evaluations and follow-up interviews, and we note the key features of this program and suggest how our experience may be used by other partnerships.« less

Leukemia and lymphoma account for more than 60% of deaths in captive koalas (Phascolarctos cinereus) in northeastern Australia. Although the endogenizing gammaretrovirus koala endogenous retrovirus (KoRV) was isolated from these koalas, KoRV has not been definitively associated with leukemogenesis. We performed KoRV screening in koalas from the San Diego Zoo, maintained for more than 45 y with very limited outbreeding, and the Los Angeles Zoo, maintained by continuously assimilating captive-born Australian koalas. San Diego Zoo koalas are currently free of malignant neoplasias and were infected with only endogenous KoRV, which we now term subtype "KoRV-A," whereas Los Angeles Zoo koalas with lymphomas/leukemias are infected in addition to KoRV-A by a unique KoRV we term subtype "KoRV-B." KoRV-B is most divergent in the envelope protein and uses a host receptor distinct from KoRV-A. KoRV-B also has duplicated enhancer regions in the LTR associated with increased pathology in gammaretroviruses. Whereas KoRV-A uses the sodium-dependent phosphate transporter 1 (PiT1) as a receptor, KoRV-B employs a different receptor, the thiamine transporter 1 (THTR1), to infect cells. KoRV-B is transmitted from dam to offspring through de novo infection, rather than via genetic inheritance like KoRV-A. Detection of KoRV-B in native Australian koalas should provide a history, and a mode for remediation, of leukemia/lymphoma currently endemic in this population.

The new Zooniverse initiative is addressing the data flood in the sciences through a transformative partnership between professional scientists, volunteer citizen scientists, and machines. As part of this project, we are exploring the application of machine learning techniques to data mining problems associated with the large and growing database of volunteer science results gathered by the Galaxy Zoo citizen science project. We will describe the basic challenge, some machine learning approaches, and early results. One of the motivators for this study is the acquisition (through the Galaxy Zoo results database) of approximately 100 million classification labels for roughly one million galaxies, yielding a tremendously large and rich set of training examples for improving automated galaxy morphological classification algorithms. In our first case study, the goal is to learn which morphological and photometric features in the Sloan Digital Sky Survey (SDSS) database correlate most strongly with user-selected galaxy morphological class. As a corollary to this study, we are also aiming to identify which galaxy parameters in the SDSS database correspond to galaxies that have been the most difficult to classify (based upon large dispersion in their volunter-provided classifications). Our second case study will focus on similar data mining analyses and machine leaning algorithms applied to the Galaxy Zoo catalog of merging and interacting galaxies. The outcomes of this project will have applications in future large sky surveys, such as the LSST (Large Synoptic Survey Telescope) project, which will generate a catalog of 20 billion galaxies and will produce an additional astronomical alert database of approximately 100 thousand events each night for 10 years -- the capabilities and algorithms that we are exploring will assist in the rapid characterization and classification of such massive data streams.

This report represents the prevalence of endoparasitic infections of birds in zoological gardens in Serbia. Coprological examination conducted during 2015 and 2016, involved samples from 318 individual birds belonging to 112 species, in three zoo gardens (Belgrade, Palić and Bor). Individual faeces samples were analysed by the flotation method in salt solution. The presence of endoparasites was established in 51.96% (Belgrade), 46.16% (Palić) and 16.66% (Bor) of the tested birds. We diagnosed coccidian oocysts, eggs of Capillaria spp, Heterakis spp, Trichostrongylus spp, Ascaridia spp, Syngamus trachea and eggs of yet unidentified trematode. There were no detection of parasites from the class of cestodes. Prevalence of infection with coccidia, depending on location, was in the ranges between 8.33% and 32.84%, capillariosis 2.77% and 29.41%, heterakiosis 2.56% and 12.74%, trichostrongylidosis 5.55% and 25.64%, askaridiosis 10.25% and 10.78%, syngamosis 2.94% and trematodes of unknown etiology 2.45%. Coinfections with two or three parasitic species were detected in Belgrade and Palić Zoo Gardens, while quadruple infection was established in birds of Belgrade Zoo Garden. Obtained results can be used in establishing programs for health protection of endangered bird species.

The behavior of an infant female orangutan at Dublin Zoo before and after the death of her mother was recorded using scan sampling and compared. Social interactions and associations of the infant with the other individuals in the group were also compared before and after the death of her mother. Increases in climbing and object manipulation were observed, and a decrease in resting occurred. The infant orangutan significantly increased the amount of time she spent in close contact with another related adult female in the group after her mother's death. This case study describes an example of a zoo-housed infant orangutan being successfully fostered by a related female without human intervention. It also provides a quantification of the behavior of an infant orangutan before and after being orphaned. Zoo Biol 30:205-211, 2011. © 2010 Wiley-Liss, Inc. © 2010 Wiley-Liss, Inc.

In the wild, western lowland gorillas consume a diet high in fiber and low in caloric density. In contrast, many gorillas in zoos consume a diet that is high-calorie and low in fiber. Some items commonly used in captive gorilla diets contain high levels of starch and sugars, which are minimal in the natural diet of gorillas. There is a growing concern that captive gorillas may qualify as obese. Furthermore, the leading cause of death for adult male gorillas in zoos is heart disease. In humans, a diet that is high in simple carbohydrates is associated with both obesity and the incidence of heart disease. In response to these issues, we implemented a biscuit-free diet (free of biscuits and low in fruit) and measured serum biomarkers of obesity and insulin resistance pre- and post-diet change at three institutions: North Carolina Zoological Garden, Cleveland Metroparks Zoo, and Columbus Zoo and Aquarium. We also added a resistant starch supplement to gorilla diets at two of the above institutions. We anticipated that these diet changes would positively affect biomarkers of obesity and insulin resistance. Both diet manipulations led to a reduction in insulin. Resistant starch also decreased overall serum cholesterol levels. Future research will examine these health changes in a greater number of individuals to determine if the results remain consistent with these preliminary findings. © 2014 Wiley Periodicals, Inc.

Simian immunodeficiency virus infections in vervet monkeys (Clorocebus aethiops) at an Australian zoo.

A number of monkey species, including African green monkeys and African vervet monkeys (Chlorocebus aethiops), are frequently infected in the wild and in captivity with a Simian immunodeficiency virus strain, SIVagm, a primate lentivirus. Up to 50% of African green monkeys are estimated to be infected with SIVagm. SIV strains are very closely related to HIV-2 strains, which are a cause of AIDS in humans, predominantly in western Africa, although cases in Australia have also been reported. It is generally thought that SIV is non-pathogenic in several natural hosts, including African green monkeys. Nevertheless many SIV strains induce a profound immunodeficiency virtually identical to HIV-1 induced AIDS in humans when administered to Asian macaque species such as rhesus (Macaca mulatta) or pigtailed macaques (M nemestrina). SIV infection of Asian macaque species is frequently employed as an animal model for AIDS vaccine studies. In November 1996 a group of 10 African vervet monkeys were imported from the USA for display at Victoria's Open Range Zoo in Werribee. Two animals in this group of monkeys later developed a fatal gastroenteric illness. These diagnoses led us to initiate SIV testing of the colony.

Sex chromosome differentiation began early during mammalian evolution. The karyotype of almost all placental mammals living today includes a pair of heterosomes: XX in females and XY in males. The genomes of different species may contain homologous synteny blocks indicating that they share a common ancestry. One of the tools used for their identification is the Zoo-FISH technique. The aim of the study was to determine whether sex chromosomes of some members of the Canidae family (the domestic dog, the red fox, the arctic fox, an interspecific hybrid: arctic fox x red fox and the Chinese raccoon dog) are evolutionarily conservative. Comparative cytogenetic analysis by Zoo-FISH using painting probes specific to domestic dog heterosomes was performed. The results show the presence of homologous synteny covering the entire structures of the X and the Y chromosomes. This suggests that sex chromosomes are conserved in the Canidae family. The data obtained through Zoo-FISH karyotype analysis append information obtained using other comparative genomics methods, giving a more complete depiction of genome evolution.

Lion, ungulate, and visitor reactions to playbacks of lion roars at Zoo Atlanta.

Felids in captivity are often inactive and elusive in zoos, leading to a frustrating visitor experience. Eight roars were recorded from an adult male lion and played back over speakers as auditory enrichment to benefit the lions while simultaneously enhancing the zoo visitor experience. In addition, ungulates in an adjacent exhibit were observed to ensure that the novel location and increased frequency of roars did not lead to a stress or fear response. The male lion in this study roared more in the playback phase than in the baseline phases while not increasing any behaviors that would indicate compromised welfare. In addition, zoo visitors remained at the lion exhibit longer during playback. The nearby ungulates never exhibited any reactions stronger than orienting to playbacks, identical to their reactions to live roars. Therefore, naturalistic playbacks of lion roars are a potential form of auditory enrichment that leads to more instances of live lion roars and enhances the visitor experience without increasing the stress levels of nearby ungulates or the lion themselves, who might interpret the roar as that of an intruder.

The presence of free-ranging urban birds is a risk factor for transmitting pathogens to captive animals and humans alike, including Salmonella spp. and diarrheagenic Escherichia coli. Cloacal swabs from 156 synanthropic Great egrets (Ardea alba) and feral pigeons (Columba livia domestica) that inhabit the surroundings of an urban zoo were processed for the identification of Salmonella spp. and diarrheagenic E. coli pathotypes. Bacterial species identification and genotypic characterization employed the matrix-assisted laser desorption ionization-time of flight mass spectrometry and PCR techniques, respectively, comparing their phylogenetic profiles through amplified fragment length polymorphism (AFLP) analysis. A total of 11 birds were positive for Salmonella Typhimurium (7%) and 9 individuals (5.8%) for diarrheagenic E. coli (enteropathogenic E. coli/Shiga-toxin producing E. coli [EPEC/STEC]) strains. S. Typhimurium strains presented highly similar AFLP profiles (85-100%), whereas EPEC/STEC strains showed more polymorphism. The results show free-ranging birds as carriers for both microorganisms in a zoo environment in Brazil for the first time and suggest these species as possible sources of infection to other animals as well as exposing personnel and visitors to potential zoonotic microorganisms. The presence of carriers highlights the importance of a surveillance system and the need for preventive measures to avoid attracting growing number of synanthropic avian species.

The aim of this research was evaluation of microbial contamination of air within and in the vicinity of animal waste disposal plants. Air samples were analyzed to determine total bacterial and fungal counts as well as microbial species composition. Measurements of climate conditions (temperature, humidity, air motion) and total dust concentration were also performed. Total numbers of bacteria and fungi surpassed the threshold limit values for production halls. The most abundant bacteria detected were those consisting of physiological microflora of animal dermis and mucosa. Fungal species composition proved to be most differentiated in the air beyond the plant area. Aspergillus versicolor, a pathogenic and allergenic filamentous fungus, was isolated only inside the rendering plant processing hall. The measurement results showed a low sanitary-hygienic state of air in the plant processing halls and substantial air pollution in its immediate vicinity.

The surrounding thermal environment has a direct influence on the well-being of an animal. However, few studies have investigated the microclimatic conditions that result from outdoor zoo enclosure designs and whether this affects where animals choose to spend time. Two African lions (Panthera leo) and two Siberian/Amur tigers (Panthera tigris altaica) were observed for a total of 18 full days during the summer and fall of 2009. Their activities and locations were recorded to the nearest minute of each test day. Simultaneous on-site microclimate measurements were taken of air temperature, relative humidity, solar radiation, and wind. Observations indicated that the locations where the animals chose to spend time were influenced by the microclimatic conditions. All subjects spent more time in the shade on their sunny warm days than on other days and differed from one another in their choice of shade source on all days. Temperature-comparable sunny and cloudy days showed a greater use of sun on the cloudy days. Species-specific differences between the lions (whose native habitat is hot) and the tigers (whose native habitat is temperate with cold winters) were observed with the tigers displaying more cooling behaviors than the lions in terms of solar radiation input and evaporative heat loss. The tigers were also more active than the lions. The results of this study provide new insight into how lions and tigers respond to microclimatic conditions in a captive environment.

Animal manure waste is considered as an environmental challenge especially in farming areas mainly because of gaseous emission and water pollution. Among all the pollutants emitted from manure waste, ammonia is of greatest concern as it could contribute to formation of aerosols in the air and could hardly be controlled by traditional disposal methods like landfill or composting. On the other hand, manure waste is also a renewable source for energy production. In this work, an environmental friendly animal waste disposal process with combined ammonia recovery and energy production was proposed and investigated both experimentally and economically. Lab-scale feasibility study results showed that 70% of ammonia in the manure waste could be converted to struvite as fertilizer, while solid manure waste was successfully gasified in a 10kW downdraft fixed-bed gasifier producing syngas with the higher heating value of 4.9MJ/(Nm 3 ). Based on experimental results, economic study for the system was carried out using a cost-benefit analysis to investigate the financial feasibility based on a Singapore case study. In addition, for comparison, schemes of gasification without ammonia removal and incineration were also studied for manure waste disposal. The results showed that the proposed gasification-based manure waste treatment process integrated with ammonia recovery was most financially viable. Copyright © 2017 Elsevier Ltd.

Varanid lizards have been maintained in zoological parks for more than a century, yet few studies to date have attempted to pinpoint significant health issues affecting their management or areas of captive husbandry that are in need of improvement. In an effort to identify and better understand some of the husbandry-related challenges and health issues specifically affecting varanids in zoos, this study examined mortality in 16 species maintained at the Bronx Zoo between 1968 and 2009. Out of 108 records reviewed, complete necropsy reports were available for 85 individuals. Infection-related processes including bacterial (15.3%), protozoal (12.9%), nematode (9.4%), and fungal (3.5%) infections accounted for the greatest number of deaths (47.1%). Noninfectious diseases including female reproductive disorders (7.1%), neoplasia (7.1%), gout (10.8%), and hemipenal prolapse (1.3%) accounted for 29.4% of deaths. Multiple disease agents were responsible for 5.9% of deaths, and a cause for death could not be determined for 17.7% of individuals. Reproductive complications accounted for 11.5% of female deaths, but were identified in 23.1% of females. Although not necessarily the cause for death, gout was present in 18.8% of individuals. Differences in mortality between species, genders, and origin (captive-bred vs. wild-caught) were also evaluated. The results of this study corroborate earlier findings that identify bacterial infections, neoplasia, female reproductive disorders, gout, and endoparasitism as major sources of mortality in captive varanids. In light of these results, we discuss potential etiologies and offer recommendations for improving captive management practices in zoos. © 2012 Wiley Periodicals, Inc.

Highlights: • Produced bio-fuels (bio-oil and bio-char) from some animal fatty wastes. • Investigated the effects of main parameters on pyrolysis products distribution. • Determined the suitable conditions for the production of the maximum of bio-oil. • Characterized bio-oils and bio-chars obtained from several animal fatty wastes. - Abstract: Several animal (lamb, poultry and swine) fatty wastes were pyrolyzed under nitrogen, in a laboratory scale fixed-bed reactor and the main products (liquid bio-oil, solid bio-char and syngas) were obtained. The purpose of this study is to produce and characterize bio-oil and bio-char obtained from pyrolysis of animal fatty wastes. Themore » maximum production of bio-oil was achieved at a pyrolysis temperature of 500 °C and a heating rate of 5 °C/min. The chemical (GC–MS analyses) and spectroscopic analyses (FTIR analyses) of bio-oil showed that it is a complex mixture consisting of different classes of organic compounds, i.e., hydrocarbons (alkanes, alkenes, cyclic compounds…etc.), carboxylic acids, aldehydes, ketones, esters,…etc. According to fuel properties, produced bio-oils showed good properties, suitable for its use as an engine fuel or as a potential source for synthetic fuels and chemical feedstock. Obtained bio-chars had low carbon content and high ash content which make them unattractive for as renewable source energy.« less

Human health is a major concern when considering the disposal of large quantities of animal waste. Health concerns could arise from exposure to pathogens and excess nitrogen associated with this form of pollution. The objective was to collect and analyze health data related to selected bacterial infections associated with the use of animal waste in Louisiana. An analysis of adverse health effects has been conducted based on the incidence/prevalence rates of campylobacteriosis, E. coli O157:H7 infection, salmonellosis and shigellosis. The number of reported cases increased during the summer months. Analysis of health data showed that reported disease cases of E. coli O157:H7 were highest among Caucasian infants in the 0-4 year old age category and in Caucasian children in the 5-9 year old age category. Fatalities resulting from salmonellosis are low and increases sharply with age. The number of reported cases of shigellosis was found to be higher in African American males and females than in Caucasians. The high rate of identification in the younger population may result from the prompt seeking of medical care, as well as the frequent ordering of stool examination when symptoms become evident among this group of the population. The association with increasing age and fatality due to salmonellosis could be attributed to declining health and weaker immune systems often found in the older population. It is concluded that both animal waste and non-point source pollution may have a significant impact on human health.

Enteric pathogens in animal waste that is not properly processed can contaminate the environment and food. The persistence of pathogens in animal waste depends upon the waste treatment technology, but little is known about persistence of porcine viruses. Our objectives were to characterize the porcine enteric viruses (porcine noroviruses [PoNoVs], porcine sapoviruses [PoSaVs], rotavirus A [RV-A], RV-B, and RV-C) in fresh feces or manure and to evaluate the effects of different candidate environmentally superior technologies (ESTs) for animal waste treatment on the detection of these viruses. Untreated manure and samples collected at different stages during and after treatment were obtained from swine farms that used conventional waste management (CWM) and five different candidate ESTs. The RNA from porcine enteric viruses was detected by reverse transcription-PCR and/or seminested PCR; PoSaV and RV-A were also detected by enzyme-linked immunosorbent assay. Cell culture immunofluorescence (CCIF) and experimental inoculation of gnotobiotic (Gn) pigs were used to determine RV-A/C infectivity in posttreatment samples. The PoSaV and RV-A were detected in pretreatment samples from each farm, whereas PoNoV and RV-C were detected in pretreatment feces from three of five and four of five farms using the candidate ESTs, respectively. After treatment, PoSaV RNA was detected only in the samples from the farm using CWM and not from the farms using the candidate ESTs. RV-A and RV-C RNAs were detected in four of five and three of four candidate ESTs, respectively, after treatment, but infectious particles were not detected by CCIF, nor were clinical signs or seroconversion detected in inoculated Gn pigs. These results indicate that only RV-A/C RNA, but no viral infectivity, was detected after treatment. Our findings address a public health concern regarding environmental quality surrounding swine production units. PMID:17601821

Antibodies to Toxoplasma gondii were determined in 167 mammals in three zoos in Mexico City, Mexico, using the modified agglutination test (MAT). Overall, antibodies to T. gondii were found in 89 (53.3%) of the 167 animals tested. Antibodies were found in 35 of 43 wild Felidae: 2 of 2 bobcats (Lynx rufus); 4 of 4 cougars (Puma concolor); 10 of 13 jaguars (Panthera onca); 5 of 5 leopards (Panthera pardus); 7 of 7 lions (Panthera leo); 2 of 3 tigers (Panthera tigris); 2 of 3 ocelots (Leopardus pardalis); 2 of 2 Sumatran tigers (Panthera tigris sumatrae); lof 2 Jaguarundi (Herpailurus jagouaroundi); but not in 0 of 2 oncillas (Leopardus tigrinus). Such high seroprevalence in wild felids is of public health significance because of the potential of oocyst shedding. Four of 6 New World primates (2 of 2 Geoffroy's spider monkeys [Ateles geoffroyi], 1 of 3 Patas monkeys [Erythrocebus patas], and 1 of 1 white-headed capuchin [Cebus capucinus]) had high MAT titers of 3,200, suggesting recently acquired infection; these animals are highly susceptible to clinical toxoplasmosis. However, none of these animals were ill. Seropositivity to T. gondii was found for the first time in a number of species.

During the 19th and early 20th century zoological gardens ranged among the most prominent places of popular natural history While aristocratic owners of earlier menageries installed animal collections mostly to symbolize their power over nature as well as to display their extensive diplomatic relations, the zoological gardens founded from the 1830s onwards all over Europe by members of the local bourgeois elites were supposed to mediate their social and political values by "enjoyably educating" a broader public. The new zoos were introduced as places at the antipodes of the frenzy, noise and motion of modern urban life, as spaces of pure, authentic nature whose observation would teach people a reasonable and responsible way of life in a civilised bourgeois community. Taking the Berlin Zoo as an example this paper questions these programmatic imaginations by showing how popular Naturkunde (natural history) was informed by cultures of urban entertainment and spectacle. It discusses the numerous relations and productive tensions that evolved out of the establishment of a "realm of nature" in the middle of the ever growing modern metropolis and investigates the consequences the zoo's rise as "the city's most important attraction" around the turn of the century had for the public perception of natural history as well as for the institution's scientific program.

This study was based on the food waste to animal feed demonstration projects in China. A safety analysis of animal feeds from three typical treatment processes (i.e., fermentation, heat treatment, and coupled hydrothermal treatment and fermentation) was presented. The following factors are considered in this study: nutritive values characterized by organoleptic properties and general nutritional indices; the presence of bovine- and sheep-derived materials; microbiological indices for Salmonella, total coliform (TC), total aerobic plate counts (TAC), molds and yeast (MY), Staphylococcus Aureus (SA), and Listeria; chemical contaminant indices for hazardous trace elements such as Cr, Cd, and As; and nitrite and organic contaminants such as aflatoxin B1 (AFB1) and hexachlorocyclohexane (HCH). The present study reveals that the feeds from all three conversion processes showed balanced nutritional content and retained a certain feed value. The microbiological indices and the chemical contaminant indices for HCH, dichlorodiphenyltrichloroethane (DDT), nitrite, and mercury all met pertinent feed standards; however, the presence of bovine- and sheep-derived materials and a few chemical contaminants such as Pb were close to or might exceed the legislation permitted values in animal feeding. From the view of treatment techniques, all feed retained part of the nutritional values of the food waste after the conversion processes. Controlled heat treatment can guarantee the inactivation of bacterial pathogens, but none of the three techniques can guarantee the absence of cattle- and sheep-derived materials and acceptable levels of certain contaminants. The results obtained in this research and the feedstuffs legislation related to animal feed indicated that food waste-derived feed could be considered an adequate alternative to be used in animal diets, while the feeding action should be changed with the different qualities of the products, such as restrictions on the application

A total of 2475 animals from Germany, both captive and wild, were tested for antibodies against Francisella tularensis to obtain more knowledge about the presence of this pathogen in Germany. An indirect and a competitive ELISA served as screening methods, positive and inconclusive samples were confirmed by Western blot. Of the zoo animals sampled between 1992 and 2007 (n = 1122), three (0·3%) were seropositive. The seroconversion of a hippopotamus in Berlin Zoo was documented. From 1353 serum samples of wild foxes (Vulpes vulpes), raccoon dogs (Nyctereutes procyonoides) and wild boars (Sus scrofa), collected between 2005 and 2009 in the federal state of Brandenburg (surrounding Berlin), a total of 101 (7·5%) tested positive for antibodies to F. tularensis lipopolysaccharide. Our results indicate a higher seroprevalence of F. tularensis in wildlife in eastern Germany than commonly assumed. Furthermore, we found foxes and raccoon dogs to be biological indicators for tularaemia.

Research with humans and other animals suggests that walking benefits physical health. Perhaps because these links have been demonstrated in other species, it has been suggested that walking is important to elephant welfare, and that zoo elephant exhibits should be designed to allow for more walking. Our study is the first to address this suggestion empirically by measuring the mean daily walking distance of elephants in North American zoos, determining the factors that are associated with variations in walking distance, and testing for associations between walking and welfare indicators. We used anklets equipped with GPS data loggers to measure outdoor daily walking distance in 56 adult female African (n = 33) and Asian (n = 23) elephants housed in 30 North American zoos. We collected 259 days of data and determined associations between distance walked and social, housing, management, and demographic factors. Elephants walked an average of 5.3 km/day with no significant difference between species. In our multivariable model, more diverse feeding regimens were correlated with increased walking, and elephants who were fed on a temporally unpredictable feeding schedule walked 1.29 km/day more than elephants fed on a predictable schedule. Distance walked was also positively correlated with an increase in the number of social groupings and negatively correlated with age. We found a small but significant negative correlation between distance walked and nighttime Space Experience, but no other associations between walking distances and exhibit size were found. Finally, distance walked was not related to health or behavioral outcomes including foot health, joint health, body condition, and the performance of stereotypic behavior, suggesting that more research is necessary to determine explicitly how differences in walking may impact elephant welfare.

Distance walked was also positively correlated with an increase in the number of social groupings and negatively correlated with age. We found a small but significant negative correlation between distance walked and nighttime Space Experience, but no other associations between walking distances and exhibit size were found. Finally, distance walked was not related to health or behavioral outcomes including foot health, joint health, body condition, and the performance of stereotypic behavior, suggesting that more research is necessary to determine explicitly how differences in walking may impact elephant welfare.

Despite ample focus on this endangered species, conservation planning for chimpanzees residing outside Africa has proven a challenge because of the lack of ancestry information. Here, we analysed the largest number of chimpanzee samples to date, examining microsatellites in >100 chimpanzees from the range of the species in Africa, and 20% of the European zoo population. We applied the knowledge about subspecies differentiation throughout equatorial Africa to assign origin to chimpanzees in the largest conservation management programme globally. A total of 63% of the genotyped chimpanzees from the European zoos could be assigned to one of the recognized subspecies. The majority being of West African origin (40%) will help consolidate the current breeding programme for this subspecies and the identification of individuals belonging to the two other subspecies so far found in European zoos can form the basis for breeding programmes for these. Individuals of various degree of mixed ancestry made up 37% of the genotyped European zoo population and thus highlight the need for appropriate management programmes guided by genetic analysis to preserve maximum genetic diversity and reduce hybridization among subspecies.

Moon Zoo is a citizen science project that utilises internet crowd-sourcing techniques. Moon Zoo users are asked to review high spatial resolution images from the Lunar Reconnaissance Orbiter Camera (LROC), onboard NASA's LRO spacecraft, and perform characterisation such as measuring impact crater sizes and identify morphological 'features of interest'. The tasks are designed to address issues in lunar science and to aid future exploration of the Moon. We have tested various methodologies and parameters therein to interrogate and reduce the Moon Zoo crater location and size dataset against a validated expert survey. We chose the Apollo 17 region as a test area since it offers a broad range of cratered terrains, including secondary-rich areas, older maria, and uplands. The assessment involved parallel testing in three key areas: (1) filtering of data to remove problematic mark-ups; (2) clustering methods of multiple notations per crater; and (3) derivation of alternative crater degradation indices, based on the statistical variability of multiple notations and the smoothness of local image structures. We compared different combinations of methods and parameters and assessed correlations between resulting crater summaries and the expert census. We derived the optimal data reduction steps and settings of the existing Moon Zoo crater data to agree with the expert census. Further, the regolith depth and crater degradation states derived from the data are also found to be in broad agreement with other estimates for the Apollo 17 region. Our study supports the validity of this citizen science project but also recommends improvements in key elements of the data acquisition planning and production.
