Experimental Evidence for Spatial Learning in Cuttlefish (Sepia officinalis )  

Microsoft Academic Search

Laboratory mazes were used to study spatial-learning capabilities in cuttlefish (Sepia officinalis), using escape for reinforcement. In preliminary observations, cuttlefish in an artificial pond moved actively around the environment and appeared to learn about features of their environment. In laboratory experiments, cuttlefish exited a simple alley maze more quickly with experience and retained the learned information. Similar improvement was not

Color matching on natural substrates in cuttlefish, Sepia officinalis  

Microsoft Academic Search

The camouflaging abilities of cuttlefish (Sepia officinalis) are remarkable and well known. It is commonly believed that cuttlefish—although color blind—actively match various colors\\u000a of their immediate surroundings, yet no quantitative data support this notion. We assembled several natural substrates chosen\\u000a to evoke the three basic types of camouflaged body patterns that cuttlefish express (uniform\\/stipple, mottle, and disruptive)\\u000a and measured the

Present status of the French Atlantic fishery for cuttlefish ( Sepia officinalis)  

Microsoft Academic Search

Fishery statistics for the period 1989–1996 indicates that cuttlefish (Sepia officinalis Linnaeus, 1758) is the main cephalopod resource exploited by the French fishery. Most cuttlefish landings come from demersal trawlers, while artisanal coastal trap net catches appear to be a minor component of cuttlefish fishing. Fishery statistics from all available databases were analysed to (a) evaluate the quality of the

A preliminary analysis of sleep-like states in the cuttlefish Sepia officinalis.  

PubMed

Sleep has been observed in several invertebrate species, but its presence in marine invertebrates is relatively unexplored. Rapid-eye-movement (REM) sleep has only been observed in vertebrates. We investigated whether the cuttlefish Sepia officinalis displays sleep-like states. We find that cuttlefish exhibit frequent quiescent periods that are homeostatically regulated, satisfying two criteria for sleep. In addition, cuttlefish transiently display a quiescent state with rapid eye movements, changes in body coloration and twitching of the arms, that is possibly analogous to REM sleep. Our findings thus suggest that at least two different sleep-like states may exist in Sepia officinalis. PMID:22701609

The use of background matching vs. masquerade for camouflage in cuttlefish Sepia officinalis

Cuttlefish, Sepia officinalis, commonly use their visually-guided, rapid adaptive camouflage for multiple tactics to avoid detection or recognition by predators.

Symmetrical crypsis and asymmetrical signalling in the cuttlefish Sepia officinalis  

PubMed Central

The salience of bilateral symmetry to humans has led to the suggestion that camouflage may be enhanced in asymmetrical patterns. However, the importance of bilateral symmetry in visual signals (and overall morphology) may constrain the evolution of asymmetrical camouflage, resulting in the bilaterally symmetrical cryptic patterns that we see throughout the animal kingdom. This study investigates the cuttlefish (Sepia officinalis), which can control the degree of symmetry in its coloration. Ten juvenile S. officinalis were filmed in two behavioural contexts (cryptic and threatened) to test the prediction that cryptic patterns will be expressed more asymmetrically than an anti-predator signal known as the ‘deimatic display’. Cryptic body patterns, particularly those with a disruptive function, were found to exhibit a high degree of bilateral symmetry. By contrast, the components of the deimatic display were often expressed asymmetrically. These results are contrary to the predicted use of symmetry in defensive coloration, indicating that the role of symmetry in both crypsis and visual signalling is not as straightforward as previously suggested.

Mechanisms of population structuring in giant australian Cuttlefish Sepia apama.  

PubMed

While a suite of approaches have been developed to describe the scale, rate and spatial structure of exchange among populations, a lack of mechanistic understanding will invariably compromise predictions of population-level responses to ecosystem modification. In this study, we measured the energetics and sustained swimming capacity of giant Australian cuttlefish Sepia apama and combined these data with information on the life-history strategy, behaviour and circulation patterns experienced by the species to predict scales of connectivity throughout parts of their range. The swimming capacity of adult and juvenile S. apama was poor compared to most other cephalopods, with most individuals incapable of maintaining swimming above 15 cm s(-1). Our estimate of optimal swimming speed (6-7 cm s(-1)) and dispersal potential were consistent with the observed fine-scale population structure of the species. By comparing observed and predicted population connectivity, we identified several mechanisms that are likely to have driven fine-scale population structure in this species, which will assist in the interpretation of future population declines.

Comparison in nutritional quality between wild and cultured cuttlefish Sepia pharaonis  

NASA Astrophysics Data System (ADS)

In this study, the proximate composition and the amino and fatty acid profiles of shrimp Litopenaeus vannamei (prey) and wild and cultured cuttlefish Sepia pharaonis (the latter fed the prey) were determined and compared with FAO/WHO recommendations. The resulting scores for isoleucine, phenylalanine+tyrosine, histidine, lysine, threonine, and tryptophan in cultured cuttlefish were ?150. The ratio of EAA (essential amino acids)/nonessential amino acids in cultured cuttlefish (0.82) was higher than in the wild form (0.80). All EAA amino acid scores for cultured cuttlefish were higher than their wild counterparts, except for histidine and tryptophan. Both groups of cuttlefish possessed similar saturated fatty acid content, with the cultured containing much more total (?) monounsaturated fatty acids, ? n-6 polyunsaturated fatty acids (PUFA), and eicosapentaenoic acid (C20:5 n-3) but less ? n-3 PUFA, arachidonic acid (C20:4 n-6), and docosahexaenoic acid (C22:6 n-3) than their wild counterparts. Therefore, the present results suggest that these cultured cuttlefish were better than the wild form for human health. Notably, these results also indicate that the nutritional composition of these cuttlefish might have been significantly affected by diet.

The use of background matching vs. masquerade for camouflage in cuttlefish Sepia officinalis.

Cuttlefish, Sepia officinalis, commonly use their visually-guided, rapid adaptive camouflage for multiple tactics to avoid detection or recognition by predators. Two common tactics are background matching and resembling an object (masquerade) in the immediate area. This laboratory study investigated whether cuttlefish preferentially camouflage themselves to resemble a three-dimensional (3D) object in the immediate visual field (via the mechanism of masquerade/deceptive resemblance) rather than the 2D benthic substrate surrounding them (via the mechanisms of background matching or disruptive coloration). Cuttlefish were presented with a combination of benthic substrates (natural rocks or artificial checkerboard and grey printouts) and 3D objects (natural rocks or cylinders with artificial checkerboards and grey printouts glued to the outside) with visual features known to elicit each of three camouflage body pattern types (Uniform, Mottle and Disruptive). Animals were tested for a preference to show a body pattern appropriate for the 3D object or the benthic substrate. Cuttlefish responded by masquerading as the 3D object, rather than resembling the benthic substrate, only when presented with a high-contrast object on a substrate of lower contrast. Contrast is, therefore, one important cue in the cuttlefish's preference to resemble 3D objects rather than the benthic substrate. PMID:21964504

Quantification of cuttlefish (Sepia officinalis) camouflage: a study of color and luminance using in situ spectrometry.  

PubMed

Cephalopods are renowned for their ability to adaptively camouflage on diverse backgrounds. Sepia officinalis camouflage body patterns have been characterized spectrally in the laboratory but not in the field due to the challenges of dynamic natural light fields and the difficulty of using spectrophotometric instruments underwater. To assess cuttlefish color match in their natural habitats, we studied the spectral properties of S. officinalis and their backgrounds on the Aegean coast of Turkey using point-by-point in situ spectrometry. Fifteen spectrometry datasets were collected from seven cuttlefish; radiance spectra from animal body components and surrounding substrates were measured at depths shallower than 5 m. We quantified luminance and color contrast of cuttlefish components and background substrates in the eyes of hypothetical di- and trichromatic fish predators. Additionally, we converted radiance spectra to sRGB color space to simulate their in situ appearance to a human observer. Within the range of natural colors at our study site, cuttlefish closely matched the substrate spectra in a variety of body patterns. Theoretical calculations showed that this effect might be more pronounced at greater depths. We also showed that a non-biological method ("Spectral Angle Mapper"), commonly used for spectral shape similarity assessment in the field of remote sensing, shows moderate correlation to biological measures of color contrast. This performance is comparable to that of a traditional measure of spectral shape similarity, hue and chroma. This study is among the first to quantify color matching of camouflaged cuttlefish in the wild. PMID:23254307

A new haemocyanin in cuttlefish (Sepia officinalis) eggs: sequence analysis and relevance during ontogeny  

PubMed Central

Background Haemocyanin is the respiratory protein of most of the Mollusca. In cephalopods and gastropods at least two distinct isoforms are differentially expressed. However, their physiological purpose is unknown. For the common cuttlefish Sepia officinalis, three isoforms are known so far, whereas for only two of them the complete mRNA sequences are available. In this study, we sequenced the complete mRNA of the third haemocyanin isoform and measured the relative expression of all three isoforms during embryogenesis to reveal a potential ontogenetic relevance. Results The cDNA of isoform 3 clearly correlates to the known Sepia officinalis haemocyanin subunits consisting of eight functional units and an internal duplicated functional unit d. Our molecular phylogenetic analyses reveal the third isoform representing a potentially ancestral haemocyanin isoform, and the analyses of the expression of haemocyanin type 3 reveal that haemocyanin type 3 only can be observed within eggs and during early development. Isoforms 1 and 2 are absent at these stages. After hatching, isoform 3 is downregulated, and isoform 1 and 2 are upregulated. Conclusions Our study clearly shows an embryonic relevance of the third isoform, which will be further discussed in the light of the changes in the physiological function of haemocyanin during ontogeny. Taken together with the fact that it could also be the isoform closest related to the common ancestor of cuttlefish haemocyanin, the phylogeny of cuttlefish haemocyanin may be recapitulated during its ontogeny.

Complete mitochondrial genome of the common cuttlefish Sepia pharaonis (Sepioidea, Sepiidae).  

PubMed

In this study, the complete mitochondrial genome of the common cuttlefish Sepia pharaonis was determined first. The genome was 16,208?bp in length and contained 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes and 2 main non-coding regions [both are control regions (CR)], the gene composition and order of which were similar to most other invertebrates. The overall base composition of S. pharaonis is T: 36.3%, C: 14.7%, A: 40.9% and G: 8.1%, with a hightly A?+?T bias of 77.2%. Two control regions all contain termination-associated sequences and conserved sequence blocks. This mitogenome sequence data would play an important role in the investigations of the phylogenetic relationships, taxonomic resolution and phylogeography of the Sepiidae. PMID:23725482

Evidence for distributed light sensing in the skin of cuttlefish, Sepia officinalis  

PubMed Central

We report that the skin of cuttlefish, Sepia officinalis, contains opsin transcripts suggesting a possible role of distributed light sensing for dynamic camouflage and signalling. The mRNA coding for opsin from various body regions was amplified and sequenced, and gene expression was detected in fin and ventral skin samples. The amino acid sequence of the opsin polypeptide that these transcripts would produce was identical in retina and fin tissue samples, but the ventral skin opsin transcripts differed by a single amino acid. The diverse camouflage and signalling body patterns of cephalopods are visually controlled, and these findings suggest a possible additional mechanism of light sensing and subsequent skin patterning. Cuttlefish, along with a number of other cephalopod species, have been shown to be colour-blind. Since the opsin in the fin is identical to that of the retina (?max = 492 nm), and the ventral transcripts are also unlikely to be spectrally different, colour discrimination by the skin opsins is unlikely. However, spectral discrimination could be provided by involving other skin structures (chromatophores and iridophores), which produce changeable colours and patterns. This ‘distributed sensing’ could supplement the otherwise visually driven dynamic camouflage system by assisting with colour or brightness matching to adjacent substrates. PMID:20392722

Microbiological quality of cuttlefish (Sepia pharaonis) fillets stored in dry and wet ice.  

PubMed

Microbiological quality of cuttlefish (Sepia pharaonis) fillets stored in three different ice conditions was studied. Fillets stored in wet ice at a ratio of 1:1 (package III) were sensorially acceptable for only 18 h, while that stored in dry ice at 1:1 (package I) and combination of dry ice and wet ice at 1:0.2:0.5 (package II) were in acceptable condition up to 24 h without re-icing and thus there was an extension of shelf life by about 33%. Total bacterial load was 7 log?? cfu/g at the end of the storage period. Total psychrophilic population increased from zero to 7 log?? cfu/g while total lactic acid bacteria from zero to 5 log?? cfu/g. H?S producers were detected only at 18 h, with a count of 1 log?? cfu/g. Sulphite-reducing Clostridia increased gradually from zero to 110 most probable number count/g. Fresh cuttlefish fillets carried a bacterial flora of Micrococcus, Planococcus, Streptococcus, Moraxella, Proteus and Aeromonas. Pseudomonas was dominant in wet ice pack, while Aeromonas was dominant in both the dry ice and combination pack. Immediately after packing, the temperatures recorded in packages I, II and III were 10.5, 1.2 and 3.0?°C, respectively, which drastically decreased in 1 h and then maintained and finally increased gradually. The results indicate that use of combination of dry ice and wet ice is economical and very much useful to seafood industries, as this package considerably reduced the cost of air freight, as well as improved the quality and shelf life of cuttlefish.

Identification and expression of two oxytocin/vasopressin-related peptides in the cuttlefish Sepia officinalis.  

PubMed

Two novel members of the oxytocin/vasopressin superfamily have been identified in the cephalopod Sepia officinalis. Oxytocin/vasopressin gene sequences were cloned by Race PCR. The two precursors we identified exhibit the classical organization of OT/VP superfamily precursors: a signal peptide followed by a nonapeptide and a neurophysin domain. The neurophysin domain is entirely conserved for the cuttlefish precursors, but the nonapeptides and the signal peptides differ. The first nonapeptide, called sepiatocin, is highly homologous to Octopus vulgaris octopressin. The second nonapeptide, called pro-sepiatocin, shows sequence homologies with a Crustacean oxytocin/vasopressin-like peptide identified in Daphnia culex and with a novel form of oxytocin described in New World monkeys. The expression of pro-sepiatocin is restricted to the supraesophageal and subesophageal masses of the brain whereas sepiatocin is expressed in the entire central nervous system. Sepiatocin, as described for octopressin, modulates the contractile activity of several muscles such as penis, oviduct and vena cava muscles; this suggests its involvement in reproduction and blood circulation. Pro-sepiatocin is released in the hemolymph; it is a neurohormone able to target numerous peripheral organs. PMID:23764263

Comparison of the ontogeny of hunting behavior in pharaoh cuttlefish (Sepia pharaonis) and oval squid (Sepioteuthis lessoniana).  

PubMed

Animals adopt various forms of hunting according to their ecological, morphological, and cognitive features, and their specific hunting skills are acquired ontogenetically in relation to these features. It is noted that cuttlefish and squid hunt prey through the elongation of tentacles used specifically to capture prey. However, these two cephalopods have different lifestyles, leading to questions such as whether hunting skill is acquired similarly after birth and whether tentacle elongation is behaviorally identical. To address these questions, we observed and compared how captive pharaoh cuttlefish (Sepia pharaonis) and oval squid (Sepioteuthis lessoniana) attack prey during their early life stages. Like the adults, S. pharaonis hatchlings used the tentacular lunge attack, whereas S. lessoniana hatchlings used the arm-opening attack. S. lessoniana began to exhibit the tentacular strike attack after 30 days of age. In addition to timing of the emergence of a specific hunting mode, some differences were observed in the physical aspect of hunting behavior. For cuttlefish, maximum tentacle length and maximum speed of tentacle elongation increased from hatching to 30 days of age and then decreased. In contrast, for squid, maximum tentacle length increased from hatching to 30 days of age and then became constant. The distance to prey was positively correlated with maximum length and speed of tentacle elongation in S. pharaonis and with maximum swimming speed in S. lessoniana. These results show that cuttlefish mainly use an ambush strategy and that squid use a pursuit strategy. Possible causes for the ontogenetic differences in hunting behavior are discussed.

The W-shaped pupil in cuttlefish (Sepia officinalis): functions for improving horizontal vision.  

PubMed

The eyes of cuttlefish (Sepia officinalis) have a modified horizontal slit-pupil with a distinctive W-shape in bright light, while in darkness the pupil is circular. Two suggestions have previously been made for a function of the W-shape: (1) camouflaging the eye; (2) providing distance information. Since neither of these suggestions can fully explain the function of this pupil across the entire visual field, particularly the frontal and caudal periphery, we re-addressed the question of its functional significance. We took infra-red images of the eyes of live S. officinalis at different light intensities and from different viewing angles. This allowed us to determine the shape and light-admitting area of the pupil for different parts of the visual field. Our data show that the W-shaped pupil projects a blurred "W" directly onto the retina and that it effectively operates as vertical slits for the frontal and caudal parts of the visual field. We also took images of the natural habitat of S. officinalis and calculated the average vertical brightness distribution in the visual habitat. Computing a retinal illumination map shows that the W-shaped pupil is effective in balancing a vertically uneven light field: The constricted pupil reduces light from the dorsal part of the visual field significantly more than it reduces light from the horizontal band. This will cut the amount of direct sunlight that is scattered by the lens and ocular media, and thus improve image contrast particularly for the dimmer parts of the scene. We also conclude that the pupil provides even attenuation along the horizontal band, whereas a circular pupil would attenuate the image relatively more in the important frontal and caudal periphery of the visual field.

Influence of environmental parameters on the life-history and population dynamics of cuttlefish Sepia officinalis in the western Mediterranean  

NASA Astrophysics Data System (ADS)

The cuttlefish Sepia officinalis constitutes an important fishery resource in the Mediterranean, where it is exploited by both the bottom trawl and small-scale fleet. However, there is currently scarce information on the Mediterranean stocks, since most studies on the population dynamics of this species have been undertaken in the northeast Atlantic. In this work we first analysed different aspects of the cuttlefish life-history from the western Mediterranean such as population structure, reproduction and the trade-offs between somatic condition and reproduction investments. Secondly, we investigated the effects of different environmental parameters (e.g. climate indices, sea surface temperature (SST), rainfall, chlorophyll-a concentration (Chla) and moon phase) on these populations, analysing several landing time series spanning the last 45 years. Our results revealed that Mediterranean cuttlefish populations exhibit strong seasonal variations owing to a reproductive migration towards coastal waters. The positive relationships between somatic and reproductive condition pointed to an income breeder strategy; this was reinforced by the percentage of empty stomachs, which was lowest just before the reproductive period peak. Despite the putative high sensitivity of cephalopod populations to external abiotic factors, our results showed that Mediterranean cuttlefish populations were not affected by most of the environmental parameters investigated. Significant effects were found for SST and a local climatic index, but no or very weak influences were evident for other parameters such as large-scale climatic phenomena (e.g. North Atlantic Oscillation, Mediterranean Oscillation) or other locally-related variables (e.g. rainfall, Chla). Our results revealed a shift in the cuttlefish population dynamics in the early 1980s, which could be related to important changes in the local hydroclimatology reported by previous authors.

Response of female cuttlefish Sepia officinalis (Cephalopoda) to mirrors and conspecifics: evidence for signaling in female cuttlefish.  

PubMed

Cuttlefish have a large repertoire of body patterns that are used for camouflage and interspecific signaling. Intraspecific signaling by male cuttlefish has been well documented but studies on signaling by females are lacking. We found that females displayed a newly described body pattern termed Splotch toward their mirror image and female conspecifics, but not to males, prey or inanimate objects. Female cuttlefish may use the Splotch body pattern as an intraspecific signal, possibly to reduce agonistic interactions. The ability of females to produce a consistent body pattern in response to conspecifics and mirrors suggests that they can recognize same-sex conspecifics using visual cues, despite the lack of sexual dimorphism visible to human observers.

Effect of early feeding experience on subsequent prey preference by cuttlefish, Sepia officinalis.  

PubMed

Food preferences were investigated in cuttlefish during the first 3 months' posthatching, using choice tests between crabs, shrimps, and young fish. The results showed that without previous feeding experience, cuttlefish preferred shrimps on Day 3. This suggests an innate food preference; however, it was possible to induce a preference for an originally nonpreferred prey item in 3-day-old and naïve cuttlefish, demonstrating the flexibility of this initial behavioral preference in response to previous individual experience. This preference suggests a learning process involving a form of long-term memory, demonstrated for the first time in juvenile cuttlefish. Until Day 30, juvenile cuttlefish fed exclusively shrimps chose shrimps. This preference probably depends on their previous feeding experience. Finally, it appears that from Day 60, cuttlefish reared on the same restricted diet have a tendency to switch their preference to novel prey items, which diversify their diet. PMID:15549683

Expression of the SOFaRP2 gene in the central nervous system of the adult cuttlefish Sepia officinalis.  

PubMed

FMRFamide-related Peptides (FaRPs) are involved in a variety of physiological processes, including reproduction, feeding, development, body patterning and osmoregulation in vertebrates and invertebrates. Here we investigate the expression pattern of cuttlefish Sepia officinalis FaRP2 gene in the brain by in situ hybridization. The SOFaRP2 gene was found to be expressed most intensively in the posterior chromatophore lobe, vasomotor lobe and subvertical lobe. In addition, positive staining was also found in the fin lobe, brachial lobe, anterior chromatophore lobe, anterior, dorsal and lateral basal lobes, inferior and superior frontal lobes, and optic lobe. The expression pattern of SOFaRP2 suggests its involvement in chromatophore regulation, feeding behavior, and learning and memory. PMID:23465584

A review of the factors influencing spawning, early life stage survival and recruitment variability in the common cuttlefish (Sepia officinalis).  

PubMed

Global landings of cephalopods (cuttlefish, squid and octopus) have increased dramatically over the past 50 years and now constitute almost 5% of the total world's fisheries production. At a time when landings of many traditional fin-fish stocks are continuing to experience a global decline as a result of over-exploitation, it is expected that fishing pressure on cephalopod stocks will continue to rise as the fishing industry switch their focus onto these non-quota species. However, long-term trends indicate that landings may have begun to plateau or even decrease. In European waters, cuttlefish are among the most important commercial cephalopod resource and are currently the highest yielding cephalopod group harvested in the north-east Atlantic, with the English Channel supporting the main fishery for this species. Recruitment variability in this short-lived species drives large fluctuations in landings. In order to provide sustainable management for Sepia officinalis populations, it is essential that we first have a thorough understanding of the ecology and life history of this species, in particular, the factors affecting spawning, early life stage (ELS) survival and recruitment variability. This review explores how and why such variability exists, starting with the impact of maternal effects (e.g. navigation, migration and egg laying), moving onto the direct impact of environmental variation on embryonic and ELSs and culminating on the impacts that these variations (maternal and environmental) have at a population level on annual recruitment success.

Characterization of Homeobox Genes Reveals Sophisticated Regionalization of the Central Nervous System in the European Cuttlefish Sepia officinalis  

PubMed Central

Cephalopod mollusks possess a number of anatomical traits that often parallel vertebrates in morphological complexity, including a centralized nervous system with sophisticated cognitive functionality. Very little is known about the genetic mechanisms underlying patterning of the cephalopod embryo to arrive at this anatomical structure. Homeodomain (HD) genes are transcription factors that regulate transcription of downstream genes through DNA binding, and as such are integral parts of gene regulatory networks controlling the specification and patterning of body parts across lineages. We have used a degenerate primer strategy to isolate homeobox genes active during late-organogenesis from the European cuttlefish Sepia officinalis. With this approach we have isolated fourteen HD gene fragments and examine the expression profiles of five of these genes during late stage (E24-28) embryonic development (Sof-Gbx, Sof-Hox3, Sof-Arx, Sof-Lhx3/4, Sof-Vsx). All five genes are expressed within the developing central nervous system in spatially restricted and largely non-overlapping domains. Our data provide a first glimpse into the diversity of HD genes in one of the largest, yet least studied, metazoan clades and illustrate how HD gene expression patterns reflect the functional partitioning of the cephalopod brain.

The effects of season and sex in the metal levels of mature common cuttlefish (Sepia officinalis) in Mersin Bay, Northeastern Mediterranean.  

PubMed

The effects of sex and season on metal levels of the mantle of the common cuttlefish that was caught from Mersin Bay were evaluated. The annual range of mantle length (ML), total length (TL), and weight of common cuttlefish specimens were 110 to 183 mm, 380 to 581 mm, and 150.24 to 477.13 g, respectively. The annual range of metal levels in the mantle tissue of common cuttlefish were: 2.34 to 3.89 ?g Cd g(-1), 0.30 to 0.63 ?g Cr g(-1), 0.15 to 0.54 ?g Pb g(-1), 2.35 to 14.90 ?g Cu g(-1), 23.22 to 51.88 ?g Zn g(-1), and 5.12 to 10.65 ?g Fe g(-1). Cu levels of females were significantly higher (P < 0.05) than those found in male throughout all the seasons while Pb levels were lower (P < 0.05) in males than females. Cr levels in the mantle tissue of cuttlefish did not change throughout the seasons. On the contrary, Cd, Pb, Cu, Zn, and Fe levels in the mantle tissue of cuttlefish changed throughout all the seasons. The highest Cd, Zn, and Fe levels were obtained in spring while the highest Cu levels were obtained in autumn. It was also found out that this species was rich in terms of metal levels, particularly, Cd, Cu, Zn, and Fe. It was found out that the mantle tissue of the common cuttlefish, Sepia officinalis, which was caught from Mersin Bay, was contaminated with Cd in all the seasons. PMID:22417374

Chemical composition and tissue energy density of the cuttlefish (Sepia apama) and its assimilation efficiency by Diomedea albatrosses.  

PubMed

The cuttlefish Sepia apama Gray (Mollusca: Cephalopoda) is a seasonally abundant food resource exploited annually by moulting albatrosses throughout winter and early spring in the coastal waters of New South Wales, Australia. To assess its nutritional value as albatross forage, we analysed S. apama for water, lipid protein, ash contents, energy density and amino acid composition. Because albatrosses consistently consume S. apama parts preferentially in the order of head, viscera and mantle, we analysed these sections separately, but did not identify any nutritional basis for this selective feeding behaviour. The gross energy value of S. apama bodies was 20.9 kJ/g dry mass, but their high water content (>83%; cf <70% for fish) results in a relatively low energy density of 3.53 kJ/g. This may contribute to a need to take large meals, which subsequently degrade flight performance. Protein content was typically >75% dry mass, whereas fat content was only about 1%. Albatrosses feed on many species of cephalopods and teleost fish, and we found the amino acid composition of S. apama to be comparable to a range of species within these taxa. We used S. apama exclusively in feeding trials to estimate the energy assimilation efficiency for Diomedea albatrosses. We estimated their nitrogen-corrected apparent energy assimilation efficiency for consuming this prey to be 81.82 ± 0.72% and nitrogen retention as 2.90 ± 0.11 g N kg(-1) d(-1). Although S. apama has a high water content and relatively low energy density, its protein composition is otherwise comparable to other albatross prey species. Consequently, the large size and seasonal abundance of this prey should ensure that albatrosses remain replete and adequately nourished on this forage while undergoing moult. PMID:20640855

Depth perception: cuttlefish (Sepia officinalis) respond to visual texture density gradients.  

PubMed

Studies concerning the perceptual processes of animals are not only interesting, but are fundamental to the understanding of other developments in information processing among non-humans. Carefully used visual illusions have been proven to be an informative tool for understanding visual perception. In this behavioral study, we demonstrate that cuttlefish are responsive to visual cues involving texture gradients. Specifically, 12 out of 14 animals avoided swimming over a solid surface with a gradient picture that to humans resembles an illusionary crevasse, while only 5 out of 14 avoided a non-illusionary texture. Since texture gradients are well-known cues for depth perception in vertebrates, we suggest that these cephalopods were responding to the depth illusion created by the texture density gradient. Density gradients and relative densities are key features in distance perception in vertebrates. Our results suggest that they are fundamental features of vision in general, appearing also in cephalopods. PMID:24942108

Microanatomy and ultrastructure of outer mantle epidermis of the cuttlefish, Sepia esculenta (Cephalopoda: Sepiidae).  

PubMed

This study describes the ultrastructural characteristics of external epidermis of mantle of Sepia esculenta using light and electron microscopy. The epidermis was thicker on the ventral surface than on the dorsal surface, with a higher secretory cell distribution on the ventral surface than on the dorsal surface. The epidermis was a single layer composed of epithelial cells, secretory cells, ciliated cells and neuroglial cells. Epithelial cells were columnar with well-developed microvilli on the free surface, and the microvilli were covered with glycocalyx. The epithelial cells were connected to the neighboring cells by tight junctions and membrane interdigitations of the apico-frontal surface. Well-developed microfilaments were arranged in a vertical direction in the cortical cytoplasm. The secretory cells were categorized into three types (A, B and C) in accordance with the light microscopical characteristics and ultrastructures of the secretory granules. The distribution of these cells was in the following order: Type A>Type B>Type C. SEM observation revealed that the secretory pore size of the Type A secretory cells was approximately 8.6 ?m×12.2 ?m. Cytoplasm displayed a red color as the result of Masson's trichrome stain and H-E stain, and contained polygonal granules of approximately 1.2 ?m2 with a high electron density. The secretory pore size of the Type B secretory cells was approximately 10.1 ?m×12.1 ?m. As the results of AB-PAS (pH 2.5) and AF-AB (pH 2.5) reactions, the cytoplasm displayed a red color. The cells contained membrane bounded secretory granules with very low electron density. The secretory pore of the Type C secretory cells was circular shape, and approximately 5.5 ?m×5.5 ?m. Cytoplasm was found to be homogeneous under H-E stain and Masson's trichrome stain, and displayed a red color. As the result of AB-PAS (pH 2.5) reaction, the cytoplasm displayed a red color. The electron density of the secretory substance was the highest among the three types of secretory cells. The ciliated cells had a ciliary tuft on the free surface and were distributed throughout the mantle with the exception of the adhesive organs. Neuroglial cells were connected to the basal membrane, epithelial cells, secretory cells and nerve fibers through cytoplasmic process, and contained neurosecretory granules with high electron density within the cytoplasm.

Purification and molecular cloning of SE-cephalotoxin, a novel proteinaceous toxin from the posterior salivary gland of cuttlefish Sepia esculenta.  

PubMed

Cephalopods contain toxins in their salivary glands, presumably to paralyze prey animals such as crabs and bivalves. Proteinaceous toxins (called cephalotoxins) with crab lethality have previously been purified from three species of octopodiform cephalopods (octopuses) but their detailed properties and primary structures have remained unknown. In this study, salivary glands of six species of decapodiform cephalopods were newly found to be toxic; three species of cuttlefish were lethal only to crabs and three species of squid to both mice and crabs. A proteinaceous toxin (named SE-cephalotoxin) in the salivary gland of cuttlefish Sepia esculenta was soluble only in high-salt solvents. This unique solubility enabled us to purify SE-cephalotoxin by gel filtration HPLC and hydroxyapatite HPLC. SE-cephalotoxin was shown to be a 100 kDa monomeric glycoprotein with an LD(50) (against crabs) of 2 microg/kg. Based on the determined partial amino acid sequence, a full-length cDNA (3402 bp) coding for SE-cephalotoxin was cloned by RT-PCR and RACE. The SE-cephalotoxin precursor protein (1052 amino acid residues) is composed of a signal peptide (region 1-21), propeptide (region 22-29) and mature protein (region 30-1052). A database search failed to find any proteins sharing homology with SE-cephalotoxin. PMID:18694775

Effects of increased pCO2 and temperature on trace element (Ag, Cd and Zn) bioaccumulation in the eggs of the common cuttlefish, Sepia officinalis  

NASA Astrophysics Data System (ADS)

Cephalopods play a key role in many marine trophic networks and constitute alternative fisheries resources, especially given the ongoing decline in finfish stocks. Along the European coast, the eggs of the cuttlefish Sepia officinalis are characterized by an increasing permeability of the eggshell during development, which leads to selective accumulation of essential and non-essential elements in the embryo. Temperature and pH are two critical factors that affect the metabolism of marine organisms in the coastal shallow waters. In this study, we are testing the effects of pH and temperature through a crossed (3×2) laboratory experiment. Seawater pH showed a strong effect on the egg weight and non-significant impact on the hatchlings weight at the end of development implying egg swelling process and embryo growth disturbances. The lower pH of incubation seawater of eggs, the more the hatchlings accumulated 110m Ag in their tissues. The 109Cd CF decreased with increasing pH and 65Zn CF reached the maximal values pH 7.85, independent of temperature. Our results suggest that pH and temperature affected both the permeability properties of the eggshell and the embryo metabolism. To the best of our knowledge, this is one of the first studies on the ocean acidification and ocean warming consequences on the metal uptake in marine organisms, stimulating further interest to evaluate the likely ecotoxicological impact of the global change on the early-life stage of the cuttlefish.

Visual interpolation for contour completion by the European cuttlefish (Sepia officinalis) and its use in dynamic camouflage  

PubMed Central

Cuttlefish rapidly change their appearance in order to camouflage on a given background in response to visual parameters, giving us access to their visual perception. Recently, it was shown that isolated edge information is sufficient to elicit a body pattern very similar to that used when a whole object is present. Here, we examined contour completion in cuttlefish by assaying body pattern responses to artificial backgrounds of ‘objects’ formed from fragmented circles, these same fragments rotated on their axis, and with the fragments scattered over the background, as well as positive (full circles) and negative (homogenous background) controls. The animals displayed similar responses to the full and fragmented circles, but used a different body pattern in response to the rotated and scattered fragments. This suggests that they completed the broken circles and recognized them as whole objects, whereas rotated and scattered fragments were instead interpreted as small, individual objects in their own right. We discuss our findings in the context of achieving accurate camouflage in the benthic shallow-water environment. PMID:22337697

Can cuttlefish learn by observing others?  

PubMed

Observational learning is the ability to learn through observing others' behavior. The benefit of observational learning is apparent in that individuals can save time and energy without trial-and-error, thus enhance the chance of survival and reproduction. Cephalopods (octopus, squid, and cuttlefish) have the most sophisticated central nervous system among invertebrates, and it is conceivable that cephalopods can develop some forms of cognition. Although it has been suggested that octopuses have the capacity of observational learning, a previous study indicates that cuttlefish do not improve their predation tactics by observing conspecifics. Given that the danger avoidance is important for animals' survival, we sought to reevaluate whether cuttlefish show some form of observational learning or observational conditioning under threatening conditions. Cuttlefish (Sepia pharaonis) were divided into three groups: the Experiencer group, the Observer group, and the Control group. In the training phase, a toy submarine was remotely controlled to expel the cuttlefish from its initially preferred place to establish the threat-place association in the Experiencer group. In the Observer group, the threat-place association was established by expelling a conspecific demonstrator at the observer's initially preferred place while the observer watched the whole process from behind a transparent divider. In the Control group, the observer watched a conspecific and a static toy submarine without actual threat. In the testing phase, the choice of safe place in the absence of threat was used to probe the learning/conditioning of cuttlefish. In the Experiencer group, we found that animals chose the safe place more often than their initially preferred place after training, an indication of the association learning/conditioning. However, in the Observer group, only a subset of animals showed this threat-place association by observation, while the place preference was unchanged in the Control group. These results indicate that most cuttlefish did not learn by observing others, but individual differences exist, and some cuttlefish may have the potential of observational learning/conditioning within their cognitive capacities.

Nine novel angiotensin I-converting enzyme (ACE) inhibitory peptides from cuttlefish (Sepia officinalis) muscle protein hydrolysates and antihypertensive effect of the potent active peptide in spontaneously hypertensive rats.  

PubMed

This study aimed to identify novel ACE inhibitory peptides from the muscle of cuttlefish. Proteins were hydrolyzed and the hydrolysates were then subjected to various types of chromatography to isolate the active peptides. Nine ACE inhibitory peptides were isolated and their molecular masses and amino acid sequences were determined using ESI-MS and ESI-MS/MS, respectively. The structures of the most potent peptides were identified as Val-Glu-Leu-Tyr-Pro, Ala-Phe-Val-Gly-Tyr-Val-Leu-Pro and Glu-Lys-Ser-Tyr-Glu-Leu-Pro. The first peptide displayed the highest ACE inhibitory activity with an IC50 of 5.22?M. Lineweaver-Burk plots suggest that Val-Glu-Leu-Tyr-Pro acts as a non-competitive inhibitor against ACE. Furthermore, antihypertensive effects in spontaneously hypertensive rats (SHR) also revealed that oral administration of Val-Glu-Leu-Tyr-Pro can decrease systolic blood pressure significantly (p<0.01). These results suggest that the Val-Glu-Leu-Tyr-Pro would be a beneficial ingredient for nutraceuticals and pharmaceuticals acting against hypertension and its related diseases. PMID:25306378

Cuttlefish use visual cues to determine arm postures for camouflage  

PubMed Central

To achieve effective visual camouflage, prey organisms must combine cryptic coloration with the appropriate posture and behaviour to render them difficult to be detected or recognized. Body patterning has been studied in various taxa, yet body postures and their implementation on different backgrounds have seldom been studied experimentally. Here, we provide the first experimental evidence that cuttlefish (Sepia officinalis), masters of rapid adaptive camouflage, use visual cues from adjacent visual stimuli to control arm postures. Cuttlefish were presented with a square wave stimulus (period = 0.47 cm; black and white stripes) that was angled 0°, 45° or 90° relative to the animals' horizontal body axis. Cuttlefish positioned their arms parallel, obliquely or transversely to their body axis according to the orientation of the stripes. These experimental results corroborate our field observations of cuttlefish camouflage behaviour in which flexible, precise arm posture is often tailored to match nearby objects. By relating the cuttlefishes' visual perception of backgrounds to their versatile postural behaviour, our results highlight yet another of the many flexible and adaptive anti-predator tactics adopted by cephalopods.

Selective signalling by cuttlefish to predators.  

PubMed

Rather than simply escaping, prey animals often attempt to deter an attack by signalling to an approaching predator, but this is a risky strategy if it allows time for the predator to draw closer (especially when the signal is a bluff). Because prey are vulnerable to multiple predators, the hunting techniques of which vary widely, it could well be beneficial for a prey animal to discriminate predators and to signal only to those that are likely to be deterred. Higher vertebrates make alarm calls that can identify the type of predator to the signaller's conspecifics, and a recent study shows that squirrels direct an infrared deterrent signal specifically at infrared-sensitive pit-vipers and not at other snakes. We show here that naïve juvenile cuttlefish (Sepia officinalis L.) use a visual signal selectively during encounters with different predatory species. We analysed sequences of defensive behaviours produced by cuttlefish, to control for effects of relative threat level (or 'response urgency'). This showed that a high contrast 'eyespot' signal, known as the deimatic display, was used before flight against visually oriented teleost fish, but not crabs and dogfish, which are chemosensory predators.

Comparative morphology of changeable skin papillae in octopus and cuttlefish.  

PubMed

A major component of cephalopod adaptive camouflage behavior has rarely been studied: their ability to change the three-dimensionality of their skin by morphing their malleable dermal papillae. Recent work has established that simple, conical papillae in cuttlefish (Sepia officinalis) function as muscular hydrostats; that is, the muscles that extend a papilla also provide its structural support. We used brightfield and scanning electron microscopy to investigate and compare the functional morphology of nine types of papillae of different shapes, sizes and complexity in six species: S. officinalis small dorsal papillae, Octopus vulgaris small dorsal and ventral eye papillae, Macrotritopus defilippi dorsal eye papillae, Abdopus aculeatus major mantle papillae, O. bimaculoides arm, minor mantle, and dorsal eye papillae, and S. apama face ridge papillae. Most papillae have two sets of muscles responsible for extension: circular dermal erector muscles arranged in a concentric pattern to lift the papilla away from the body surface and horizontal dermal erector muscles to pull the papilla's perimeter toward its core and determine shape. A third set of muscles, retractors, appears to be responsible for pulling a papilla's apex down toward the body surface while stretching out its base. Connective tissue infiltrated with mucopolysaccharides assists with structural support. S. apama face ridge papillae are different: the contraction of erector muscles perpendicular to the ridge causes overlying tissues to buckle. In this case, mucopolysaccharide-rich connective tissue provides structural support. These six species possess changeable papillae that are diverse in size and shape, yet with one exception they share somewhat similar functional morphologies. Future research on papilla morphology, biomechanics and neural control in the many unexamined species of octopus and cuttlefish may uncover new principles of actuation in soft, flexible tissue.

New protocols to improve the deposition and hatching of Sepia officinalis' eggs.  

PubMed

The objective of this study was the development of hatching protocols in controlled conditions to obtain juveniles, in order to restock and increase the resource of Sepia officinalis. The study was divided into the following phases: development and application of artificial surfaces at specific sites of the Molise coast in Italy; induction of eggs hatching and juveniles maintenance under controlled condition; juveniles introduction into specific sites and assessment their increment; experimental data elaboration. The obtained results concerned both the effectiveness of the artificial surfaces tasted during the study and the importance of the recovery of the eggs laid on artificial surfaces (artefacts and fishing gear) for preservation and the management of the Sepia officinalis resource. The induction tests conducted on eggs hatching under controlled conditions confirmed what described in the extant literature. Water salinity was detected as the only limiting factor, with values ? 20% related to the absence of hatching. The described practices for harvesting and induction of hatching for the production of juvenile cuttlefish may be endorsed by the operators at relatively low cost and throughout the year, with obvious economic benefits.

Five new species of dicyemid mesozoans (Dicyemida: Dicyemidae) from two Australian cuttlefish species, with comments on dicyemid fauna composition.  

PubMed

Five new species of dicyemid mesozoans in two genera are described from two Australian cuttlefish species, Sepia apama Gray (giant Australian cuttlefish) and S. novaehollandiae Hoyle (nova cuttlefish): Dicyema coffinense n. sp. from S. apama collected from Coffin Bay, South Australia (SA), Australia; D. koinonum n. sp. from S. apama and S. novaehollandiae collected from Gulf St Vincent (GSV) and Spencer Gulf (SG), SA, Australia; D. multimegalum n. sp. from S. apama collected from Cronulla and North Bondi, New South Wales, Australia; D. vincentense n. sp. from S. novaehollandiae collected from GSV, SA, Australia; and Dicyemennea spencerense n. sp. from S. novaehollandiae and S. apama collected from SG, SA, Australia. Totals of 51 S. apama and 27 S. novaehollandiae individuals were examined, of which all except for four S. apama were infected by at least one dicyemid species. Dicyemid parasites were also observed in host individuals that were held in tanks for 2-3 months prior to examination, including nematogen-exclusive infections, leading to questions about persistence of dicyemids after host death and the mechanism responsible for the switch between a nematogen phase and a rhombogen phase. Variations in host size, calotte shape and collection locality are explored as predictors of differences in observed composition of the parasite fauna. In particular, dicyemid parasite fauna varied with host collection locality. As these parasites are highly host-species specific, their use as biological tags to assess cephalopod population structure using a combined morphological and molecular approach is discussed. This study increases the number of dicyemid species described from Australian cephalopods from five to ten, and from 117 to 122 species described worldwide. PMID:24048746

Lower hypoxia thresholds of cuttlefish early life stages living in a warm acidified ocean  

PubMed Central

The combined effects of future ocean acidification and global warming on the hypoxia thresholds of marine biota are, to date, poorly known. Here, we show that the future warming and acidification scenario led to shorter embryonic periods, lower survival rates and the enhancement of premature hatching in the cuttlefish Sepia officinalis. Routine metabolic rates increased during the embryonic period, but environmental hypercapnia significantly depressed pre-hatchling's energy expenditures rates (independently of temperature). During embryogenesis, there was also a significant rise in the carbon dioxide partial pressure in the perivitelline fluid (PVF), bicarbonate levels, as well as a drop in pH and oxygen partial pressure (pO2). The critical partial pressure (i.e. hypoxic threshold) of the pre-hatchlings was significantly higher than the PVF oxygen partial pressure at the warmer and hypercapnic condition. Thus, the record of oxygen tensions below critical pO2 in such climate scenario indicates that the already harsh conditions inside the egg capsules are expected to be magnified in the years to come, especially in populations at the border of their thermal envelope. Such a scenario promotes untimely hatching and smaller post-hatching body sizes, thus challenging the survival and fitness of early life stages. PMID:23926158

Simulated, Emulated, and Physical Investigative Analysis (SEPIA) of networked systems.  

SciTech Connect

This report describes recent progress made in developing and utilizing hybrid Simulated, Emulated, and Physical Investigative Analysis (SEPIA) environments. Many organizations require advanced tools to analyze their information system's security, reliability, and resilience against cyber attack. Today's security analysis utilize real systems such as computers, network routers and other network equipment, computer emulations (e.g., virtual machines) and simulation models separately to analyze interplay between threats and safeguards. In contrast, this work developed new methods to combine these three approaches to provide integrated hybrid SEPIA environments. Our SEPIA environments enable an analyst to rapidly configure hybrid environments to pass network traffic and perform, from the outside, like real networks. This provides higher fidelity representations of key network nodes while still leveraging the scalability and cost advantages of simulation tools. The result is to rapidly produce large yet relatively low-cost multi-fidelity SEPIA networks of computers and routers that let analysts quickly investigate threats and test protection approaches.

Relations between total mercury, methylmercury and selenium in five tissues of Sepia officinalis captured in the south Portuguese coast.  

PubMed

Mercury, methylmercury and selenium were determined in digestive gland, branchial hearts, mantle, kidney and gills of Sepia officinalis from two areas of the south Portuguese coast. To the best of our knowledge these are the first data on Hg, MeHg and Se in branchial hearts, kidney and gills of cuttlefish. Digestive gland, branchial hearts and kidney presented higher levels of Hg and Se than mantle and gills. Methylmercury was significantly higher in digestive gland, branchial hearts and mantle. The enhanced levels of Hg in digestive gland and branchial heart reinforce the elevated storage capacity of these two tissues. The percentage of MeHg varied from 6.1% in gills to 92% in mantle. Linear and positive MeHg-Hg relations were obtained for the five tissues, being the better relation and higher slope observed for mantle, followed by branchial hearts, digestive gland, kidney and gills. The Se:Hg molar ratios showed a surplus of Se in all tissues. Calculations based on the equimolarity of Se:Hg point that 95-99% of Se are not linked to Hg (Se free). The negligible quantity of Se associated with Hg suggests that the mechanism of MeHg demethylation was not triggered in none of the tissues, presumably because the threshold for MeHg toxicity was not achieved.

Integration of sediment contamination with multi-biomarker responses in a novel potential bioindicator (Sepia officinalis) for risk assessment in impacted estuaries.  

PubMed

For the purpose of biomonitoring, species that combine ecological and commercial importance may provide a link between ecological and human health risk. The common cuttlefish, Sepia officinalis, holds both characteristics in south-western Europe, albeit remaining unsurveyed in ecotoxicological studies. Cuttlefish collected from an impacted estuary in SW Portugal and a reference location off the coast were analysed for a battery of biomarker responses in the digestive gland and gills. The contrast to reference animals revealed that biomarker responses, especially those related to oxidative stress, were consistent with sediment contamination by PAHs, even in a situation that combines complex toxicant mixtures, moderate levels of contamination and high ecotoxicological diversity. However, environmental parameters related to the differences between shore and estuarine habitats should not be overruled. Also, digestive gland metallothionein retained significant specificity to metals even though previous studies in the area with clams and fish failed to trigger a conclusive response. The highest net differences in biomarker responses were detected in the gills, likely indicating higher sensitivity to environmental stressors. Still, the digestive gland responses were overall the most consistent with sediment contamination and effectively differentiated between estuarine industrial- and rural-impacted sites. The results indicate that S. officinalis may be a candidate to meet the European Union's requirements for efficient biomonitoring programmes, with the additional importance of being cosmopolitan, abundant, commercially valuable and combining the molluscan biology that has been granting bivalves their high value for biomonitoring with foraging behaviour, thus better able to reflect anthropogenic stressors impacting a wider area than sedentary organisms. Nevertheless, further investigations in unpolluted sites are needed to better evaluate the background levels of biomarker responses in the species. PMID:24142132

PubMed

Three new species of dicyemid mesozoans are described for the first time from Australian octopus and cuttlefish species. Dicyemennea floscephalum sp. n. is described from Octopus berrima Stranks et Norman (southern keeled octopus) collected from Spencer Gulf and Gulf St. Vincent, South Australia, Australia and represents the first description of a species of Dicyemennea Whitman, 1883 from Australian waters. Dicyema papuceum sp. n. and D. furuyi sp. n. are described from Sepia papuensis Hoyle (Papuan cuttlefish) collected from Shark Bay, Western Australia, Australia. Dicyemennea floscephalum sp. n. is a medium to large species that reaches approximately 4.9 mm in length. The vermiform stages are characterised by having 23-28 peripheral cells, and a disc-shaped, flower-like calotte in larger individuals. An anterior abortive axial cell is absent in vermiform embryos and verruciform cells were not observed in nematogens and rhombogens. Infusoriform embryos comprise 37 cells; one nucleus is present in each urn cell. Dicyema papuceum sp. n. is a small species that reaches approximately 1.1 mm in length. The vermiform stages are characterised by having 30-33 peripheral cells and a relatively small, cap-shaped calotte. An anterior abortive axial cell is absent in vermiform embryos and verruciform cells were occasionally observed in nematogens. Infusoriform embryos comprise 37 cells; two nuclei are present in each urn cell. Dicyema furuyi sp. n. is a large species that reaches approximately 5.3 mm in length. The vermiform stages are characterised by having 22-24 peripheral cells and an elongate calotte. An anterior abortive axial cell is absent in vermiform embryos and verruciform cells were not observed in nematogens and rhombogens. Infusoriform embryos comprise 37 cells; one nucleus is present in each urn cell. Three secondary nematogens were also observed in the right renal appendages of two host individuals, confirming the occurrence of this form. PMID:24261132

How visual edge features influence cuttlefish camouflage patterning.  

PubMed

Rapid adaptive camouflage is the primary defense of soft-bodied cuttlefish. Previous studies have shown that cuttlefish body patterns are strongly influenced by visual edges in the substrate. The aim of the present study was to examine how cuttlefish body patterning is differentially controlled by various aspects of edges, including contrast polarity, contrast strength, and the presence or absence of "line terminators" introduced into a pattern when continuous edges are fragmented. Spatially high- and low-pass filtered white or black disks, as well as isolated, continuous and fragmented edges varying in contrast, were used to assess activation of cuttlefish skin components. Although disks of both contrast polarities evoked relatively weak disruptive body patterns, black disks activated different skin components than white disks, and high-frequency information alone sufficed to drive the responses to white disks whereas high- and low-frequency information were both required to drive responses to black disks. Strikingly, high-contrast edge fragments evoked substantially stronger body pattern responses than low-contrast edge fragments, whereas the body pattern responses evoked by high-contrast continuous edges were no stronger than those produced by low-contrast edges. This suggests that line terminators vs. continuous edges influence expression of disruptive body pattern components via different mechanisms that are controlled by contrast in different ways.

Embryonic exposure to predator odour modulates visual lateralization in cuttlefish.  

PubMed

Predation pressure acts on the behaviour and morphology of prey species. In fish, the degree of lateralization varies between high- and low-predation populations. While lateralization appears to be widespread in invertebrates, we do not know whether heredity and early experience interact during development as in vertebrates. Here we show, for the first time, that an exposure to predator odour prior to hatching modulates visual lateralization in newly hatched cuttlefish. Only cuttlefish that have been exposed to predator odour display a left-turning bias when tested with blank seawater in a T-shaped apparatus. Exposure to predator odour all the incubation long could appear as an acute predictor of a high-predation surrounding environment. In addition, cuttlefish of all groups display a left-turning preference when tested with predator odour in the apparatus. This suggests the ability of cuttlefish to innately recognize predator odour. To our knowledge, this is the first clear demonstration that lateralization is vulnerable to ecological challenges encountered during embryonic life, and that environmental stimulation of the embryo through the olfactory system could influence the development of subsequent visual lateralization.

Delayed and asynchronous ganglionic maturation during cephalopod neurogenesis as evidenced by Sof-elav1 expression in embryos of Sepia officinalis (Mollusca, Cephalopoda).  

PubMed

Among the Lophotrochozoa, centralization of the nervous system reaches an exceptional level of complexity in cephalopods, where the typical molluscan ganglia become highly developed and fuse into hierarchized lobes. It is known that ganglionic primordia initially emerge early and simultaneously during cephalopod embryogenesis but no data exist on the process of neuron differentiation in this group. We searched for members of the elav/hu family in the cuttlefish Sepia officinalis, since they are one of the first genetic markers of postmitotic neural cells. Two paralogs were identified and the expression of the most neural-specific gene, Sof-elav1, was characterized during embryogenesis. Sof-elav1 is expressed in all ganglia at one time of development, which provides the first genetic map of neurogenesis in a cephalopod. Our results unexpectedly revealed that Sof-elav1 expression is not similar and not coordinated in all the prospective ganglia. Both palliovisceral ganglia show extensive Sof-elav1 expression soon after emergence, showing that most of their cells differentiate into neurons at an early stage. On the contrary, other ganglia, and especially both cerebral ganglia that contribute to the main parts of the brain learning centers, show a late extensive Sof-elav1 expression. These delayed expressions in ganglia suggest that most ganglionic cells retain their proliferative capacities and postpone differentiation. In other molluscs, where a larval nervous system predates the development of the definitive adult nervous system, cerebral ganglia are among the first to mature. Thus, such a difference may constitute a cue in understanding the peculiar brain evolution in cephalopods. PMID:23047428

Evidence of episodic-like memory in cuttlefish.  

PubMed

The recollection of past experiences allows us to recall what happened during a particular event, and where and when it occurred [1]. Since the first study on episodic-like memory in scrub-jays [2], there has been widespread acceptance of the idea that tests in animals should integrate the 'what', 'where' and 'when' components of a unique event that occurred in the past [3,4]. This is referred to as episodic-like memory rather than episodic memory per se, in acknowledgement of the lack of evidence for, or against, the phenomenological aspects that accompany episodic recollection in humans. So far, evidence for episodic-like memory has only been found in some birds and mammals. We show here that cuttlefish, cephalopod mollusks, keep track of what they have eaten, and where and how long ago they ate, in order to match their foraging behavior with the time of replenishing of different foods. Foraging in cuttlefish fulfils the criteria of 'what', 'where' and 'when' of unique events and thus provides behavioral evidence of episodic-like memory in an invertebrate. PMID:24309275

The "prawn-in-the-tube" procedure: what do cuttlefish learn and memorize?  

PubMed

For several decades the "prawn-in-the-tube" procedure has been extensively used in the exploration of behavioral plasticity and its neural correlates in cuttlefish. Although the nature of the task has been characterized, the effect of reinforcement and the extent of different cues cuttlefish can use to solve and memorize the task remain unclear. To determine whether cuttlefish learned to inhibit predatory behavior because of pain incurred when the tentacles hit the glass tube, the shrimp prey (typically attacked with a tentacle strike) was replaced by crabs (normally caught by a jumping strategy, using all eight arms together, which is thought less likely to be painful). We showed that the cuttlefish is still capable of learning inhibition of predatory behavior when it adopts another catching strategy, which suggests that pain from the tentacles hitting the tube has little effect on the learning process. The two latest experiments have shown that cuttlefish do not learn to inhibit predatory behavior towards a specific type of prey, but rather learn and memorize visual (light polarization) and tactile information from the glass tube. The "prawn-in-the-tube" procedure is a powerful and user-friendly tool in the investigation of the processing and retention of multisensory information in invertebrates. Our recent findings now open up new areas of investigation into the neural correlates of learning and memory processes in cuttlefish. PMID:23178535

Cellular attachment and osteoblast differentiation of mesenchymal stem cells on natural cuttlefish bone.  

PubMed

The purpose of this study was to describe an approach that aims to provide fundamental information for the application of natural cuttlefish bone. Before applying cuttlefish bone as a bone defect filling material, we evaluated proliferation, adhesion, and cell viability of human mesenchymal stem cells (hMSCs) cultured on cuttlefish bone. Cuttlefish bone was separated into two parts (dorsal shield and lamellar region) and each part was used. Cell proliferation and viability were assessed using the MTS assay and live/dead fluorescence staining method. The morphology was observed using scanning electron microscopy (SEM). hMSCs were stimulated with osteogenic medium and osteoblast differentiation was evaluated. The fluorescence images showed that the seeded cells grew well and that cell distribution was in accordance with the surface morphology of the cuttlefish bone. Compared with the dorsal shield, cells penetrated deeper into the three-dimensional inner space of the lamellar part. Furthermore, under osteogenic differentiation conditions, alkaline phosphatase activity increased and the mRNA expression of ALP, runt-related transcription factor 2, and collagen type I ?1 was increased in hMSCs cultured on both the dorsal shield and lamellar block. These results indicate the potential of cuttlefish bone as an ideal scaffold for bone regenerative materials. PMID:22447716

From Trap to Nursery. Mitigating the Impact of an Artisanal Fishery on Cuttlefish Offspring  

PubMed Central

Background Overexploitation and the impact of several types of human activities have caused declines of marine resources. The direct and active involvement of fishermen in the management of marine resources is effective not only for resource conservation, but also for changing fishermen’s attitudes. In this study, we proposed and tested the efficacy and suitability of a measure for mitigating the impact of a trap fishery on cuttlefish eggs in the North Adriatic Sea. This measure directly involves fishermen in promoting the conservation of the early, and more vulnerable, stages of the cuttlefish life cycle. Methodology/Principal findings Through surveys on fishing boats and interviews with fishermen, we found that traps placed in coastal areas during the cuttlefish breeding season have a high impact on cuttlefish eggs, with over 3 million eggs likely being destroyed by 3750 traps of 15 fishermen in less than 3 miles of coast. The use of removable ropes attached inside traps as an additional substrate for egg deposition allowed the recovery of 23.7% of the eggs deposited on the traps on average, without affecting the catch rate of adults. Experiments examining hatching success in the field highlighted the need for a careful choice of hatching sites to maximise the efficacy of the mitigation measure. Conclusions/Significance The proposed mitigation measure reduced the impact of fishing on cuttlefish eggs, with no significant effect on the commercial catch. Fishermen showed a positive attitude towards the application of this measure, which is inexpensive and easy to employ. The direct involvement of fishermen in the management of this resource and the maintenance of traditional fishing methods are a novel aspect of the proposed measure and represent the basis for its success.

Early exposure to odors changes later visual prey preferences in cuttlefish.  

PubMed

Developmental studies have shown that environmental stimulation received by a developing sensory system can alter the developmental outcome of both that sensory system and other aspects of the nervous system. We investigated the ecologically relevant question of whether prior exposure to prey early in development within one sensory modality could influence later prey choice within a different sensory modality. Cuttlefish are visual predators; they can detect prey odors but attacks on prey cannot be elicited without visual stimulation. Cuttlefish eggs were exposed to the odor of shrimp (preferred prey), crabs (non-preferred prey), mollusks (non-prey), or a seawater control (no prey). Seven days after hatching, prey preferences were tested with a visual choice test between crabs and shrimp. Hatchlings exposed to crabs odors and the seawater control were significantly more likely to attack shrimp. Hatchlings exposed to mollusk odors showed no visual prey preference, while those exposed to shrimp preferentially attacked crabs. These results demonstrate a complex relationship between an early sensory exposure and later prey preference PMID:21157990

PCL-coated hydroxyapatite scaffold derived from cuttlefish bone: morphology, mechanical properties and bioactivity.  

PubMed

In the present study, poly(?-caprolactone)-coated hydroxyapatite scaffold derived from cuttlefish bone was prepared. Hydrothermal transformation of aragonitic cuttlefish bone into hydroxyapatite (HAp) was performed at 200°C retaining the cuttlebone architecture. The HAp scaffold was coated with a poly(?-caprolactone) (PCL) using vacuum impregnation technique. The compositional and morphological properties of HAp and PCL-coated HAp scaffolds were studied by means of X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA) and scanning electron microscopy (SEM) with energy dispersive X-ray (EDX) analysis. Bioactivity was tested by immersion in Hank's balanced salt solution (HBSS) and mechanical tests were performed at compression. The results showed that PCL-coated HAp (HAp/PCL) scaffold resulted in a material with improved mechanical properties that keep the original interconnected porous structure indispensable for tissue growth and vascularization. The compressive strength (0.88MPa) and the elastic modulus (15.5MPa) are within the lower range of properties reported for human trabecular bones. The in vitro mineralization of calcium phosphate (CP) that produces the bone-like apatite was observed on both the pure HAp scaffold and the HAp/PCL composite scaffold. The prepared bioactive scaffold with enhanced mechanical properties is a good candidate for bone tissue engineering applications. PMID:24268280

Characteristics of the tertiary egg membrane of cuttlefish Sepiella maindroni de Rochebrune  

NASA Astrophysics Data System (ADS)

We separated tertiary egg membrane (TGM) from 2- and 25-day-old eggs of cuttlefish Sepiella maindroni de Rochebrune, and revealed its ultrastructure, physical (solubility, barrier property) and biochemical (histology, histochemistry, nutritional components, bacteriostasis) characteristics. The results show that TGM could not be dissolved with natural seawater, alcohol, ether or hydrochloric acid (HCl), but it could be dissolved with 2-chloroethanol, diethylamine, and sodium hydroxide (NaOH). The black TGM was more effective in blocking off mud particulates, microorganisms ( Chlorella vulgaris, Vibrio alginolyticus) and lighter than the white TGM. The elasticity of black and white TGMs was 1.8 N and 1.5 N, respectively. There were some ink particulates and rod-shaped bacteria in the black TGM. The nutritional components were different between black and white TGMs: Lipid content was lower and protein content was higher in the black TGM. TGM could also inhibit the growth of Vibrio alginolyticus.

Isolation and characterization of new polymorphic microsatellite markers from the cuttlefish Sepiella maindroni (Cephalopoda; Sepiidae).  

PubMed

Fifteen new polymorphic microsatellite loci were developed for the cuttlefish Sepiella maindroni. In 32 individuals from a wild population of coastal Ningde, Fujian Province, China, the number of alleles at these loci varied between 2 and 12, with an average of 5.86. The mean observed and expected heterozygosities were 0.6917 and 0.5993, respectively. Among these polymorphic microsatellite loci, 4 (SM2, SM19, SM40, and SM81) significantly deviated from Hardy-Weinberg equilibrium after sequential Bonferroni's correction. All of them were in linkage equilibrium. These microsatellite loci would be useful for evaluating the effect of releasing on extant S. maindroni populations as well as for investigating genetic diversity and population structure of this species.

Effects of Chitin and Sepia Ink Hybrid Hemostatic Sponge on the Blood Parameters of Mice  

PubMed Central

Chitin and sepia ink hybrid hemostatic sponge (CTSH sponge), a new biomedical material, was extensively studied for its bene?cial biological properties of hemostasis and stimulation of healing. However, studies examining the safety of CTSH sponge in the blood system are lacking. This experiment aimed to examine whether CTSH sponge has negative effect on blood systems of mice, which were treated with a dosage of CTSH sponge (135 mg/kg) through a laparotomy. CTSH sponge was implanted into the abdominal subcutaneous and a laparotomy was used for blood sampling from abdominal aortic. Several kinds of blood parameters were detected at different time points, which were reflected by coagulation parameters including thrombin time (TT), prothrombin time (PT), activated partial thromboplatin time (APTT), fibrinogen (FIB) and platelet factor 4 (PF4); anticoagulation parameter including antithrombin III (AT-III); fibrinolytic parameters including plasminogen (PLG), fibrin degradation product (FDP) and D-dimer; hemorheology parameters including blood viscosity (BV) and plasma viscosity (PV). Results showed that CTSH sponge has no significant effect on the blood parameters of mice. The data suggested that CTSH sponge can be applied in the ?eld of biomedical materials and has potential possibility to be developed into clinical drugs of hemostatic agents. PMID:24727395

Extraction, characterization and antioxidant property of chitosan from cuttlebone Sepia kobiensis (Hoyle 1885).  

PubMed

Chitin was extracted from the cuttlebone of Sepia kobiensis and chitosan was prepared through deacetylation. The chitosan was characterized for its structural, physical and thermal (CHN, DDA, FT-IR, NMR, XRD, Viscometric analysis, SEM and DSC) properties. Further, the chitosan exhibited the antioxidant activity of 50.68-74.36% at 1-10 mg ml(-1) and it also showed the reducing power of 0.28% at 1 mg ml(-1). At 10 mg ml(-1), the chitosan exhibited the scavenging ability of 46.17%, on 1,1-diphenyl-2-picrylhydrazyl radicals, 23.38-73.70% on superoxide radicals at 0.05-1.6 mg ml(-1) and 18.34% to 62.39% (0.1-3.2 mg ml(-1)) on hydroxyl radicals; whereas at 1-10 mg ml(-1) the chelating ability on ferrous ions was calculated as 49.74-73.59%. Based on the potential antioxidant activity, scavenging ability on hydroxyl radicals and chelating abilities on ferrous ions, the chitosan from the cuttlebone of S. kobiensis may not only be used as a potent natural antioxidant but also as a possible food quality enhancer ingredient in the pharmaceutical industry.

A single-factor experiment was conducted to study the effects of different temperature (15, 18, 21, 24, 27, 30, and 33 degrees C) on the embryonic development and larval growth of Sepia lycidas, aimed to search for the optimum temperature for the development and growth of S. lycidas. The results showed that temperature had significant effects on the embryonic development and larval growth of S. lycidas (P < 0.05). The suitable temperature for hatching ranged from 21 degrees C to 30 degrees C, and the optimum temperature was 24 degrees C. At the optimum temperature, the hatching rate was (93.3 +/- 2.9)%, incubation period was (24.33 +/- 0.58) d, hatching period was (6.00 +/- 1.00) d, completely absorked rate of yolk sac was (96.4 +/- 3.1)%, and newly hatched larvae mass was (0.258 +/- 0.007) g. The effective accumulated temperature model was N = 284.42/(T-12.57). The suitable temperature for the larval survival and growth ranged from 21 degrees C to 30 degrees C, and the optimum temperature was from 24 degrees C to 27 degrees C. At the optimum temperature, the survival rate ranged from 70.0% to 73.3%, and the specific growth rate was from 2.4% to 3.8%. PMID:24015570

The golden ratio autocorrelation function

On the base of the recurrence relation formalism an autocorrelation function is obtained, the continued fraction form of which corresponds to the golden ratio ones. It turns out that this GR autocorrelation is known in science and obeys all necessary conditions, in contrast to the exponential autocorrelation function. Using the Kubo approach it is shown how exponential correlations appear in the linear response theory as a result on non-Hermitian relaxation of the system.

The Influence of Sexual and Larval Selection on the Maintenance of Polymorphism at the Sepia Locus in DROSOPHILA MELANOGASTER  

PubMed Central

Sexual selection is measured between two strains of Drosophila melanogaster: a wild strain and a strain mutant at the sepia locus. Frequency-dependent male mating was found to be successful, whereas the female genotype exerted no influence. The rarer the male genotype becomes, the greater is its mating success. A selection model is built for this behavior characteristic in which selection operates differently in the two sexes. The genetic consequencies of this model upon the maintenance of genetic polymorphism at the sepia locus are compared to experimental data from previous population cage studies. The fit obtained with this sexual selection model is compared to that of the larvel selection model previously investigated. A model composed of both sexual and larval components of fitness is presented. The role that each major selection component is expected to play in experimental populations as the gene frequency changes is discussed. Sexual selection leads to an equilibrium level higher than larval selection, and the combined model is very close to the experimental values. PMID:6777247

Traceability: The golden calf (revisited)  

SciTech Connect

The ancient religious symbol of the golden calf has become a present day metaphor for a tangible but specious object that diverts the attention from an intangible, authentic, and crucial entity that it purports to represent. Peter Stein, measurement guru, for several years (1962 et seq.) has noted that calibration traceability has taken on the character of a Golden Calf.'' He has cautioned that with the present day emphasis on formal quality assurance in measurement, calibration traceability as a primary attestation of accuracy can be disproportionately emphasized to the detriment of actual measurement accuracy. This seemingly paradoxical claim is well-founded as illustrated by many examples where the more important issues of measurement qualification, validation, system characterization, and transient correction are recognized as affecting end accuracy much more critically than usual calibration errors. This paper extends Stein's areas of concern and reviews several practical examples where instrument errors of the magnitude typically revealed in standards laboratory calibration are dwarfed by the more generally consequential measurement errors of misapplication and naive reliance on highly accurate laboratory calibration of component instruments. The purpose of the paper is not to denigrate calibration nor its traceability. Rather, it is to caution that experimenters, standards and specifications writers, calibration laboratories, and measurement quality auditors must recognize these two important aspects of quality assurance as merely a partial, and certainly not a predominant, tool for the assurance of accuracy and quality in measurement. 12 refs., 1 figs.

The Binet-Fibonacci formula for Fibonacci numbers is treated as a q-number (and q-operator) with Golden ratio bases $q=\\phi$ and $Q=-1/\\phi$. Quantum harmonic oscillator for this Golden calculus is derived so that its spectrum is given just by Fibonacci numbers. Ratio of successive energy levels is found as the Golden sequence and for asymptotic states it appears as the Golden ratio. This why we called this oscillator as the Golden oscillator. By double Golden bosons, the Golden angular momentum and its representation in terms of Fibonacci numbers and the Golden ratio are derived.

The golden rule of reviewing  

USGS Publications Warehouse

A major bottleneck in the time required to publish a scientific or scholarly paper is the speed with which reviews by peers are returned to journals. Peer review is a reciprocal altruistic system in which each individual may perform every task—editors, reviewers, and authors—at different times. Journals have no way to coerce reviewers to return their critiques faster. To greatly shorten the time to publication, all actors in this altruistic network should abide by the Golden Rule of Reviewing: review for others as you would have others review for you. Say yes to reviewing whenever your duties and schedule allow; provide a thorough, fair, and constructive critique of the work; and do it at your first opportunity regardless of the deadline.

The effects of season and sex on fat, fatty acids and protein contents of Sepia officinalis in the northeastern Mediterranean Sea.  

PubMed

The effects of season and sex on the fatty acids (FAs) and proximate compositions of the mantle of the mature common cuttlefish were evaluated. The results of the proximate composition showed that the lowest lipid content was obtained from females in winter (0.74%), whereas the highest level of lipid was found in males in autumn (0.94%; p < 0.05). The protein levels of the mantle of the mature male of common cuttlefish were significantly higher (p < 0.05) than those found in female specimens. The FA compositions of each sex for all seasons ranged from 29.4% to 32.5% saturated FAs, 8.7-11.1% monounsaturated FAs and 48.2-54.6% polyunsaturated fatty acids (PUFAs). The proportions of n-3 PUFAs (44.0-50.6%) were higher than n-6 PUFAs (3.4-4.3%) regardless of sex and seasons. The levels of eicosapentaenoic acid in the mature common cuttlefish mantle in spring, autumn and winter were 15.9-17.8%, 16.3-17.2% and 15.7-16.8% while those of docosahexaenoic acid were 32.5-33.0%, 27.5-29.0% and 28.7-31.1%, respectively.

Paraparesis in a Golden Retriever.  

PubMed

A 7-year-old female spayed Golden Retriever dog presented with fever and a 10-day history of neurological signs, including ambulatory paraparesis and pelvic limb ataxia. Neurological examination initially revealed a T3-L3 myelopathy. Thoracic radiographs revealed a diffuse miliary pulmonary pattern. Endotracheal washes and fine-needle aspirates from several organs aimed at identifying a potential infectious agent or neoplastic process were all unsuccessful. Due to worsening of the clinical signs, euthanasia was elected. Necropsy findings included multifocal, pale to dark red, firm nodules infiltrating the lungs, heart, mesentery, pancreas, small intestine, brain, and spinal cord. Cytological examination of impression smears obtained from the pulmonary nodules during necropsy revealed clusters of epithelioid cells admixed with fewer spindle cells, erythrocytes, and scattered leukocytes. Clinical signs and cytological findings initially suggested the possibility of a widespread granulomatous disease or a metastatic epithelial neoplasm as possible clinical differentials in this case. The final diagnosis was based on the gross and histological findings, with confirmation following histochemistry and immunohistochemistry. PMID:24193142

Primary productivity in the Golden Horn.  

PubMed

The shores of the Golden Horn--once most important seaport of the region--represented throughout history a romantic and recreational venue. This tributary to the Bosphorus, however, became seriously polluted with the extensive industrialization and rapid population growth in Istanbul over the past century. Two main tributaries, the Alibeykoy and the Kagithane, dumped both liquid and solid waste from residential areas and industry (small and large-scale) into the Golden Horn. As a result of this pollution, the landward three to four kilometers of the estuary became swamped with sediment. The dominance of anaerobic activity resulted in a highly unpleasant smell, and the shallow depth as one progressed up the bay restricted navigation. In early 1997 The Istanbul Metropolitan Municipality began a dredging operation and gradually diverted all domestic and industrial wastewater discharge from the Golden Horn. Since then there have been remarkable improvements in water quality. This paper presents the state of eutrophication through the water body of the Golden Horn; parameters such as DO, TKN, NH(3)-N, NO(3)-N, the total phosphorus (TP) and dissolved phosphorus (PO(4)-P), phytoplankton and chlorophyll-a have been were analyzed in samples of water taken from various points in the Golden Horn. The presence of DO and the phytoplankton, both indicators of primary productivity in an aquatic body, has been evaluated in relation to former conditions. PMID:16240188

Quetzalcoatl was both man and god, myth and true history, and was worshipped through centuries in temples in the great sacred cities of Teotihuacan, Tollan, and Chichen Itza. The White god, ruler of the Toltec golden age, who sailed toward the east promising to return, remains a mystery. (Author/NQ)

Radiographic features of Golden Retriever muscular dystrophy.  

PubMed

Golden Retriever muscular dystrophy is an inherited, degenerative myopathy due to the absence of dystrophin and is used as a model of Duchenne muscular dystrophy of young boys. This report describes the radiographic abnormalities of Golden Retriever muscular dystrophy in 26 dogs. The thoracic abnormalities included diaphragmatic asymmetry (18/26), diaphragmatic undulation (18/26), and gastro-esophageal hiatal hernia (6/26). Pelvic abnormalities included narrowing of the body of the ilia (14/19), ventral deviation and curvature of the tuber ischii (14/19), elongation of the obturator foramen with a decrease in opacity of the surrounding bone (12/19), and lateral flaring of the wings of the ilia (12/19). Abdominal abnormalities consisted of hepatomegaly (14/22) and poor serosal detail (12/22). The unique thoracic abnormalities were a consistent finding in affected Golden Retriever muscular dystrophy dogs. The diagnosis of muscular dystrophy should be included in the differential list if the combination of diaphragm undulation and asymmetry, and gastro-esophageal hiatal hernia are identified. These diaphragmatic abnormalities are related to hypertrophy and hyperplasia of the diaphragm. Additionally, the skeletal changes of pelvic tilt, elongation of the pelvis, widening of the obturator foramina and thinning of the ischiatic tables appear to be specific to Golden Retriever muscular dystrophy in dogs. These pelvic abnormalities are most likely secondary to bone remodeling associated with the progressive skeletal myopathy and subsequent contracture/fibrosis. PMID:17153067

Comparative study of physico-mechanical and antioxidant properties of edible gelatin films from the skin of cuttlefish.  

PubMed

Physicochemical properties of edible films based on cuttlefish skin gelatin extracted without (G0) or with different concentrations of pepsins (5 (G5), 10 (G10) and 15 (G15) U/g of skin) were investigated. Edible films prepared with partially hydrolyzed gelatins had lower tensile strength (TS) and elongation at break (EAB), but higher water vapour permeability (WVP) and water solubility than the control film. FTIR spectra of obtained gelatin films revealed a significant loss of molecular order of the triple helix. In addition, differential scanning calorimetric (DSC) analysis indicated that partially hydrolyzed gelatine films exhibited lower transition temperature and enthalpy compared with those of control film. The properties of the films were related to their microstructure, which was observed by scanning electron microscopy. Films with G0 and G5 had a smooth surface and a more compact structure, while films prepared with G10 and G15 had coarser surface. Thus, the chain length of extracted gelatin directly affected the properties of corresponding films. PMID:23820179

The sisters of the golden section.  

PubMed

The golden proportion is widely believed to be extraordinarily prevalent in nature and the arts, which is often ascribed to it being the limit of the ratio between any two successive elements in the Fibonacci sequence. It is suggested here that the golden ratio may not be as exceptional as generally believed. Mathematically, some interesting properties are common to all members of a family of sequences, denoted ARS, characterised as solutions to the classic rabbit reproduction problem varying on some parameter, j, including the Fibonacci sequence as a prototypical member--ARS2. Furthermore, for j > 1, any limit of the ratio between successive elements in ARS(j), shares the same formal properties with all other such limits. Three actual interpretations and three further geometric applications of ARS3, all intimately analogous to corresponding ARS2 ones, are presented for the sake of illustration. Empirically, it is suggested here that, owing to the communality of interesting mathematical properties between ARS sequences, as well as between corresponding limits, nature might appear to have made use of some other limits, aside of its variegated use of the limit of ARS2--the golden ratio. Initial empirical clues are provided. Finally, the issue whether there really is special import to golden proportions in nature and the arts is revisited in view of some empirical comparisons of appearances related to Fibonacci numbers and ARS3 numbers, particular its limit (-1.466) and the inverse of that limit (-0.682). It is argued that the claim that Fibonacci-related numbers are especially distinguished seems to warrant a more qualified approach than it has often met. PMID:21936299

New "Golden" Ratios for Facial Beauty  

PubMed Central

In four experiments, we tested the existence of an ideal facial feature arrangement that could optimize the attractiveness of any face given its facial features. Participants made paired comparisons of attractiveness between faces with identical facial features but different eye-mouth distances and different interocular distances. We found that although different faces have varying attractiveness, individual attractiveness is optimized when the face’s vertical distance between the eyes and the mouth is approximately 36% of its length, and the horizontal distance between the eyes is approximately 46% of the face’s width. These “new” golden ratios match those of an average face. PMID:19896961

Productivity of golden eagles wearing backpack radiotransmitters  

USGS Publications Warehouse

We examined the association between the presence of backpack radiotransmitters and Golden Eagle (Aquila chrysaetos)reproduction (percentage of occupied territories producing young, and number of nestlings produced) over three years. The association between radio-tagging and nesting success and the number of nestlings produced varied significantly among years. A negative association with tagging was observed in one of three years, which coincided with low prey (jackrabbit) populations and a cold spring. However, small sample size and breeding by subadults may confound this result.

Sepia ink oligopeptide induces apoptosis in prostate cancer cell lines via caspase-3 activation and elevation of Bax/Bcl-2 ratio.  

PubMed

Sepia ink oligopeptide (SIO) is a tripeptide extracted from Sepia ink. To test the hypothesis that SIO inhibits prostate cancer by inducing apoptosis, the effects of SIO on the proliferation of three human prostate cancer cell lines were examined using a CCK-8 assay. SIO significantly inhibited the proliferation of DU-145, PC-3 and LNCaP cells in a time- and dose-dependent manner. Flow cytometry studies showed that exposing DU-145, PC-3 and LNCaP cells to 5, 10, or 15 mg/mL SIO for 24 h increased the percentage of the early-stage apoptotic cells from 11.84% to 38.26% (DU-145), 22.76% to 39.96% (PC-3) and 5.05% to 16.11% (LNCaP), respectively. In addition, typical morphologic changes were observed in the cells with acridine orange/ethidium bromide staining. SIO treatment induced strong S and G?/M phase cell cycle arrest in a dose-dependent manner in DU-145 and LNCaP. In contrast, SIO treatment induced strong Sub G? and G?/G? phase cell cycle arrest in a dose-dependent manner in PC-3. SIO exposure for 24 h decreased the expression of the anti-apoptotic protein Bcl-2 and increased the expression of the apoptogenic protein Bax. Moreover, the Bax/Bcl-2expression ratio was increased. Concurrently, the expression of caspase-3 was upregulated. These data support our hypothesis that SIO has anticarcinogenic properties. PMID:23170075

Drugs are often used in combination and, for pharmacologists, the manner of their interactions can cast light on drug mechanisms and biological processes. Here we provide simplified descriptions of commonly used analytical methods for analysing drug combinations and describe a new and practical experimental solution to address the mechanistic question: ‘Do two channel-blocking drugs bind at the same site?’ We define two simple mathematical models that describe the effects of two channel blockers acting simultaneously at either the same (Syntopic Model) or different (Allotopic Model) binding sites within a channel pore. We find that the optimum concentrations of two drugs for distinguishing between the two models are related to the mathematical Golden Ratio. PMID:23972927

Use of Hydrogen Peroxide to Improve Golden Shiner Egg Hatchability  

Microsoft Academic Search

The efficacy of hydrogen peroxide (H2O2) in controlling fungal infections (saprolegniasis) in the eggs of golden shiner Notemigonus crysoleucas was assessed in two experiments. Golden shiner eggs were exposed in a 15-min static bath (21°C) to 0, 50, 100, or 200 mg H2O2\\/L in the first experiment and to 0, 200, 400, and or 800 mg\\/L in the second experiment.

Native Americans who lived in the state found a bounty of fish, pleasant climates, and a rather hospitable way of life. Europeans arriving from Spain, Britain, and Russia found much to enjoy here as well in the 16th and 17th centuries. In the middle of the 19th century, the proverbial and literal "gold in them hills" brought prospectors from all corners of the globe who dreamed of making a vast fortune. The 20th century saw a feverish period of land speculation, the explosive growth of Southern California, and glittering dreamscapes promoted by real estate developers and movie moguls alike. Today, things are much different, as the state continues to attract fewer new residents every year, and taxes continue to be quite onerous for middle-income families. During the 2000s, the state did continue to grow by about 10% in terms of population, but this was meager compared with growth rates of 53% in the 1950s. Speaking on this recent transformation, Professor Dowell Myers noted, "If things go really bad in the Midwest, Southern California could be a beacon of hope. But in general, immigration has slowed down now and is not likely to turn upward." The director of the Huntington-USC Institute on California and the West, William Deverell, offered another perspective recently, "The hold California has on people has been every bit as much psychological as actual-but people are leaving. It can be very, very difficult here."The first link will take visitors to an excellent piece on the current state of California from CNN's series "Defining America".

Progress towards the 'Golden Age' of biotechnology.  

PubMed

Biotechnology uses substances, materials or extracts derived from living cells, employing 22 million Europeans in a € 1.5 Tn endeavour, being the premier global economic growth opportunity this century. Significant advances have been made in red biotechnology using pharmaceutically and medically relevant applications, green biotechnology developing agricultural and environmental tools and white biotechnology serving industrial scale uses, frequently as process feedstocks. Red biotechnology has delivered dramatic improvements in controlling human disease, from antibiotics to overcome bacterial infections to anti-HIV/AIDS pharmaceuticals such as azidothymidine (AZT), anti-malarial compounds and novel vaccines saving millions of lives. Green biotechnology has dramatically increased food production through Agrobacterium and biolistic genetic modifications for the development of 'Golden Rice', pathogen resistant crops expressing crystal toxin genes, drought resistance and cold tolerance to extend growth range. The burgeoning area of white biotechnology has delivered bio-plastics, low temperature enzyme detergents and a host of feedstock materials for industrial processes such as modified starches, without which our everyday lives would be much more complex. Biotechnological applications can bridge these categories, by modifying energy crops properties, or analysing circulating nucleic acid elements, bringing benefits for all, through increased food production, supporting climate change adaptation and the low carbon economy, or novel diagnostics impacting on personalized medicine and genetic disease. Cross-cutting technologies such as PCR, novel sequencing tools, bioinformatics, transcriptomics and epigenetics are in the vanguard of biotechnological progress leading to an ever-increasing breadth of applications. Biotechnology will deliver solutions to unimagined problems, providing food security, health and well-being to mankind for centuries to come. PMID:23797042

Fatal acute toxoplasmosis in three golden lion tamarins (Leontopithecus rosalia).  

PubMed

Fatal acute toxoplasmosis was diagnosed in three golden lion tamarins (Leontopithecus rosalia), a breeding pair and their male offspring, by histology and immunohistochemistry. The distribution and severity of lesions differed among the animals, but the small intestine and the pancreaticoduodenal lymph nodes were especially affected. Protozoal organisms consistent with Toxoplasma gondii tachyzoites, often clustered, were seen in all lesions and were specifically immunostained with a T. gondii polyclonal antibody. The infection was probably acquired orally. Several breeding groups of golden lion tamarins have succumbed to toxoplasmosis both in North American and European zoos, so this disease should be considered an important problem in this endangered species. Toxoplasma gondii can cause latent infections in New World primates and therefore could potentially induce abortions or congenital infections in wild golden lion tamarins born from latently infected reintroduced females.

The Golden ratio, ionic and atomic radii and bond lengths  

NASA Astrophysics Data System (ADS)

This work arose from the author's finding that the ratio of the radius of hydrogen, estimated recently (C.H. Suresh, N. Koga, J. Phys. Chem. A, 105, 5940 (2001)) by density functional methods, to the ground state Bohr radius is the Golden ratio, which operates in a variety of natural phenomena. It is found that the Golden ratio indeed plays a quantitative role in atomic physics. The interesting results are (1) that it arises in atomic dimensions due to the electrostatic forces between negative and positive charges; (2) that the energy of atomic hydrogen is actually equivalent to the energy of the simplest atomic condenser with the Golden mean capacity; (3) that the origin of two terms in the Rydberg equation for absorption and emission is in fact in the ground state term; (4) that all atoms can be assigned definite values of cationic and anionic radii based on the Golden ratio and covalent radii; (5) that these radii are additive and explain quantitatively bond lengths like those of alkali halides, of hydrides of many elements and of many other bonds, whether covalent or ionic or both; and (6) that the work functions of alkali metals can be evaluated using the bond lengths.

Helminth fauna of a Japanese golden eagle, Aquila chrysaetos japonica.  

PubMed

A Japanese golden eagle, Aquila chrysaetos japonica, was found dead in Nagano Prefecture PB 399-8200, Japan, and subjected to necropsy. The necropsy revealed that the entire length of the intestine was filled with several masses of intestinal parasites. The recovered helminths were identified as one digenean trematode species, Neodiplostomum reflexum; two species of nematodes, Synhimantus sp. and larvae of Porrocaecum sp.; and a single species of Acanthocephala, Centrorhynchus sp. Digenea and acanthocephalans were found in massive numbers, obliterating the intestinal lumen, which suggests that the bird died as a result of the parasitic intestinal obstruction. The same type of helminths as those observed in this case was previously recorded in crested serpent eagles (Spilornis cheela perplexus) in Japan, but the present study emphasizes the presence of the four species in the Japanese golden eagle as a new host record. To the authors' knowledge, this is the first report of N. reflexum in Japan. PMID:23272374

The golden-silk spider repairs the webbing each day, replacing half but never the whole web at one time. Its web may measure two to three feet across. The center shares a boundary with the Merritt Island National Wildlife Refuge, a 92,000-acre refuge that is a habitat for more than 331 species of birds, 31 mammals, 117 fishes, and 65 amphibians and reptiles. The marshes and open water of the refuge provide wintering areas for 23 species of migratory waterfowl, as well as a year-round home for great blue herons, great egrets, wood storks, cormorants, brown pelicans and other species of marsh and shore birds, as well as a variety of insects.

[Doctor HUANG Shi-ping's acupuncture with golden needles].  

PubMed

Taking Doctor HUANG Shi-ping as the representative, the school of Huang's golden needle is based on Chinese martial art. Golden needles are adopted as main tool. Attaching great importance on the combination of acupuncture and moxibustioin, it is also characterized with penetrating needling with long needles. Through the development of three generations, it once outshone other schools in the field of acupuncture, and became famous all over the world. It made great contribution to the development of the course of acupuncture. However, with the development of the history, the form of acupuncture education as well as apparatus were all undergone an unified reform. Therefore, Doctor HUANG Shi-ping's acupuncture school be lost gradually. PMID:24195225

San Francisco Public Library: Golden Gate International Exposition  

NSDL National Science Digital Library

Opened on February 18, 1939 the Golden Gate International Exposition was designed to celebrate the completion of the Golden Gate Bridge and the San Francisco-Oakland Bay Bridge. The theme of this exposition was "Pageant of the Pacific,â and offered a gauzy Pacific Rim influence to the art, architecture, and landscape design at the fairgrounds while blending in modernism and technological innovations. Originally running through October of 1939, it was brought back for a second round from May 25 - September 29, 1940. This digital collection from the San Francisco Public Library brings together 130 plus photos that document the built environment of this grand exposition, including shots of the Danish Pavilion, sculptors working on the various monuments around the fairgrounds, and some rather elaborate molds of the Bay Bridge.

Golden Beam Data for Proton Pencil Beam Scanning  

PubMed Central

Proton, as well as other ion, beams applied by electro-magnetic deflection in pencil-beam scanning (PBS) are minimally perturbed and thus can be quantified a-priori by their fundamental interactions in medium. This a-priori quantification permits an optimal reduction of characterizing measurements on a particular PBS delivery system. The combination of a-priori quantification and measurements will then suffice to fully describe the physical interactions necessary for treatment planning purposes. We consider, for proton beams, these interactions and derive a “Golden” beam data set. The Golden beam data set quantifies the pristine Bragg peak depth dose distribution in terms of primary, multiple Coulomb scatter, and secondary, nuclear scatter, components. The set reduces the required measurements on a PBS delivery system to the measurement of energy spread and initial phase space as a function of energy. The depth doses are described in absolute units of Gy(RBE).mm2.Gp?1, where Gp equals 109 (giga) protons, thus providing a direct mapping from treatment planning parameters to integrated beam current. We used this Golden beam data on our PBS delivery systems and demonstrate that it yields absolute dosimetry well within clinical tolerance. PMID:22330090

Complete migration cycle of golden eagles breeding in northern Quebec  

USGS Publications Warehouse

Radio tracking via satellite was initiated to study the year-round movements of Golden Eagles(Aquila chrysaetosc anadensis) breeding on the east coast of Hudson Bay, Quebec. In June and August 1992, six Golden Eagles(five adults and one juvenile) were marked, three of which completed their year-round movements. The eagles left their breeding area in mid- to late October and migrated to known wintering areas in the eastern United States. They used different routes but each followed the same general path during fall and spring migrations which lasted between 26 and 40 days,and 25 and 51 days, respectively. Eagles wintered from 93 to 135 days in areas located 1,650 to 3,000 km south of their breeding territory. In spring 1993, satellite telemetry located the eagles in their former breeding territory in late March, mid-April and early May. This study confirms previous suggestion that some breeding Golden Eagles wintering in eastern United States come from northern Quebec and describes the first successful tracking of the complete yearly migration cycle of a bird of prey.

Effect of sediment settling on controlling golden mussel invasion in water transfer project  

NASA Astrophysics Data System (ADS)

Inter-basin water transfer projects have been widely used to solve uneven distribution of water resources and water shortage in China. Along with the transferring of water resources, golden mussel (Limnoperna fortunei), the filter-collector macro-invertebrate species originating from southern China has also been inadvertently transferred to new aquatic environment, resulting in quick and uncontrolled spread of the species. The golden mussels are invasive by nature and endowed with a strong byssus for attaching onto their habitat, allowing them to easily invade natural and artificial aquatic systems, which was resulted in high-density golden mussel attachment that causes serious bio-fouling. Invasion and bio-fouling by golden mussels in water transfer systems has drawn attention widely because it has resulted in high resistance to water flow, corrosion of pipe walls and even clogging of tunnels, as well as causing water pollution and ecological imbalance in the regions that receive water infested with golden mussels. Field investigation was conducted along the East River, which is the main drinking water resource for Cantong province and Hongkong, China, to study the natural habitats of golden mussels. Surveys of water transfer tunnels which carry water from the East River to several big cities in Cantong province were done to study golden mussel invasion and attachment in tunnels. It is found that in the natural habitat, golden mussels mainly attach to bedrock and bank stones and solid surfaces facing upstream, while no golden mussels are attached on the surfaces facing downstream and suffering sediment deposition. In the water transfer tunnels, golden mussel attachment densities of 40,000 individuals/m2 mainly occurred on the portion of tunnel walls which face downwards and thus avoid sedimentation. An experiment was designed to study the effect of sediment settling on golden mussel attachment. The results showed that settling of fine sediment particles affects golden mussels by preventing them from filtering food and oxygen from water, and in this way killing them. The attachment density decreased with increased sediment deposition. Golden mussel density decreased by about 70-90% when the sedimentation rate increased by 3-6 times. Therefore, spraying with fine sediment or creating hyper-concentration of sediment water to treat golden mussels before they enter tunnels is recommended as an effective strategy for controlling golden mussel invasion and high-density bio-fouling. Key words: golden mussel invasion; bio-fouling; sediment settling; habitat; controlling strategy

Modified evisceration technique in a golden eagle (Aquila chrysaetos).  

PubMed

Two different modified techniques have been described for enucleation in raptors, including the transaural approach and the globe-collapsing procedure. This case report describes an alternative, modified evisceration procedure in a mature female Golden Eagle (Aquila chrysaetos). The advantages of this procedure are decreased anesthetic time, ease of procedure, decreased risk of excessive traction of the optic nerve, decreased intraoperative orbital trauma, and preservation of the natural symmetry of the head. The major disadvantage of this procedure is that it does not allow complete histologic examination of the globe. Patients with intraocular infection or neoplasia, or significant orbital disease may be poor candidates for this technique. PMID:21929613

Golden Bars of Consensus and the Truth Quark  

E-print Network

Scientists are imprisoned by Golden Bars of Consensus, says Burton Richter (hep-ex/0001012). A case in point is the mass of the Truth Quark. The consensus analysis of the experimental data indicates that the mass of the Truth Quark is about 170 GeV. On the other hand, an alternative analysis of the same data indicates that the mass of the Truth Quark is about 130 GeV. If the design of future experiments, including trigger, event selection, data analysis procedures, error analysis, etc., takes into account only the consensus value, and if the consensus value happens to be incorrect, then results of future experiments might be compromised.

The normal electrocardiogram of conscious golden eagles (Aquila chrysaetos).  

PubMed

The aim of this study was to describe the normal electrocardiographic patterns and values in conscious golden eagles (Aquila chrysaetos). The standard bipolar and augmented unipolar limb leads' electrocardiograms were recorded in the golden eagles. The waveforms were analyzed in all leads at 50 mm/sec and at 10 mm = 1 mV to determine P, PR (segment and interval), QRS, ST, and QT durations and P, net QRS complex, and T amplitudes. The polarity of each waveform was tabulated in all leads. The mean electrical axis for the frontal plane was calculated using standard bipolar leads II and III. The mean heart rate was 346.7 +/- 14.29 beats/min. The P wave was predominantly positive in standard bipolar leads I and II and augmented unipolar limb leads aVL and aVF. The dominant pattern ofwaveforms of the QRS complexes were QS in leads I, II, III, and aVF, whereas in leads aVR and aVL, the pattern was always R. The T wave was slightly positive in leads I, II, and aVF. The average value of the heart mean electrical axis was -85.9 +/- 7.50 degrees. Establishment of normal electrocardiogram values will facilitate a better understanding of electrocardiographic changes seen in many avian diseases. PMID:20945639

Extracting effective Higgs couplings in the golden channel  

NASA Astrophysics Data System (ADS)

Kinematic distributions in Higgs decays to four charged leptons, the so called `golden channel, are a powerful probe of the tensor structure of its couplings to neutral electroweak gauge bosons. In this study we construct the first part of a comprehensive analysis framework designed to maximize the information contained in this channel in order to perform direct extraction of the various possible Higgs couplings. To that end we first complete an earlier analytic calculation of the leading order fully differential cross sections for the golden channel signal and background to include the 4 e and 4 ? final states with interference between identical final states. We also examine the relative fractions of the different possible combinations of scalar-tensor couplings by integrating the fully differential cross section over all kinematic variables as well as show various doubly differential spectra for both the signal and background. From these analytic expressions we then construct a `generator level' analysis framework based on the maximum likelihood method. We demonstrate the ability of our framework to perform multi-parameter extractions of all the possible effective couplings of a spin-0 scalar to pairs of neutral electroweak gauge bosons including any correlations. This framework provides a powerful method for study of these couplings and can be readily adapted to include the relevant detector and systematic effects which we demonstrate in an accompanying study to follow.

Time-place learning in golden shiners (Pisces: Cyprinidae).  

PubMed

The goal of this study was to determine whether fish can learn to forage in different places at different times of the day, each place being associated with a specific time. Groups of eight golden shiners (Notemigonus crysoleucas) were kept in aquaria equipped with automatic feeders that dropped food on one side in the morning and on the other side in the afternoon, or on one side in the morning, the other side at midday, and back on the first side in the evening. After 3-4 weeks, food was withheld and the position of the fish within the aquaria was noted at 5-min intervals throughout the day. Consistent with time-place learning, most fish were on the correct side at the correct time. However, another experiment with three places instead of two provided only equivocal evidence of time-place learning; this could reflect the fact that, in the lakes they inhabit, golden shiners may need only distinguish between two places: open waters and littoral. Experiments with phase-shifts of the photoperiod showed that temporal discrimination is based on a circadian clock that can be gradually phase-advanced by 6 h in about 3 days. PMID:24896874

Valence atom with bohmian quantum potential: the golden ratio approach  

PubMed Central

Background The alternative quantum mechanical description of total energy given by Bohmian theory was merged with the concept of the golden ratio and its appearance as the Heisenberg imbalance to provide a new density-based description of the valence atomic state and reactivity charge with the aim of clarifying their features with respect to the so-called DFT ground state and critical charge, respectively. Results The results, based on the so-called double variational algorithm for chemical spaces of reactivity, are fundamental and, among other issues regarding chemical bonding, solve the existing paradox of using a cubic parabola to describe a quadratic charge dependency. Conclusions Overall, the paper provides a qualitative-quantitative explanation of chemical reactivity based on more than half of an electronic pair in bonding, and provide new, more realistic values for the so-called “universal” electronegativity and chemical hardness of atomic systems engaged in reactivity (analogous to the atoms-in-molecules framework).

Its web may measure two to three feet across and it repairs the webbing each day, replacing half but never the whole web at one time. The center shares a boundary with the Merritt Island National Wildlife Refuge, a 92,000-acre refuge that is a habitat for more than 331 species of birds, 31 mammals, 117 fishes, and 65 amphibians and reptiles. The marshes and open water of the refuge provide wintering areas for 23 species of migratory waterfowl, as well as a year-round home for great blue herons, great egrets, wood storks, cormorants, brown pelicans and other species of marsh and shore birds, as well as a variety of insects.

Implications of the Higgs discovery in the MSSM golden region  

NASA Astrophysics Data System (ADS)

If the lightest CP-even Higgs boson in the MSSM is discovered at the LHC, two measurements could be made simultaneously: the Higgs mass mh and the event rate B?(gg ? h ? ??). We study to what extent the combination of these two measurements would allow us to extract parameters in the stop mass matrix, including the off-diagonal mixing term, with a focus on the MSSM golden region where the stops are light and the mixing is large. Even though both the production cross-section and the decay amplitude are not sensitive to supersymmetric parameters outside of the stop sector, the branching ratio depends on the total decay width, which is dominated by the Higgs decay to b quarks and sensitive to both the pseudo-scalar mass mA and the supersymmetric Higgs mass ?. In the end we find mA is an important input in extracting the stop mass parameters, while a fair estimate of the off-diagonal mixing term could be obtained without prior knowledge of ?.

Saprophytic and cycloheximide resistant fungi isolated from golden hamster.  

PubMed

Healthy hair samples from golden hamsters were examined for the presence of dermatophytes and non-dermatophytes using baiting technique and direct inoculation. Thirty-four species and 2 varieties attributed to 17 genera were recovered. Paecilomyces variotii (isolated from 84.4% of the examined hair) and Aspergillus niger (81.3%) were the more frequent isolates on Sabouraud's dextrose agar (SDA) without cycloheximide. Our results have clearly demonstrated that the hair of hamster was free from true dermatophytes. Using the dilution plate method many fungal species were isolated from cage material (7 genera and 10 species + 1 variety); from faeces (10 genera and 17 species); from standard chow (3 genera and 6 species) of hamster. P. variotii which was the most frequent fungus in the preceding 3 substrates was completely absent in the presence of cycloheximide in SDA. The present study has demonstrated for the first time the isolation of Trichophyton rubrum from hamster faeces. Also, several saprophytic and cycloheximide resistant fungi were isolated. In the air of hamster cage Cladosporium cladosporioides, Penicillium chrysogenum, Alternaria alternata and Scopulariopsis brevicaulis were the most dominant species on SDA with or without cycloheximide. Using the agar diffusion method, Aloe sap, onion oil, garlic bulb extract and aqueous leaf extracts of Andropogon citratus, Euphorbia sp. and Ruta graveolens were tested for their antifungal activity on 10 fungal species. It was observed that onion oil exhibited a high inhibitory effect against most of the tested fungi. PMID:9768288

Oropouche virus experimental infection in the golden hamster (Mesocrisetus auratus).  

PubMed

Oropouche virus (OROV), of the family Bunyaviridae, is the second most frequent arbovirus causing febrile disease in Brazil. In spite of this, little is known about pathogenesis of OROV infection. This report describes an experimental model of OROV in golden hamster (Mesocricetus auratus). Following subcutaneous inoculation of OROV, over 50% of the animals developed disease characterized by lethargy, ruffled fur, shivering, paralysis, and approximately one third died. Animals were sacrificed on days 1, 3, 5, 8 and 11 post-inoculation to collect tissue samples from brain, heart, liver, lung, spleen, muscle and blood for virus titration, histology and OROV immunohistochemistry. OROV was detected in high titers in blood, liver and brain, but not in the other organs. Histopathology revealed meningoencephalitis and hepatitis, with abundant OROV antigen detected in liver and brain. Diffuse galectin-3 immunostaining in brain and liver supports microglial and Kupfer cells activation. This is the first description of an experimental model for OROV infection and should be helpful to study pathogenesis and possibly to test antiviral interventions such as drugs and vaccine candidates.

Assembly of designer TAL effectors by Golden Gate cloning.  

PubMed

Generation of customized DNA binding domains targeting unique sequences in complex genomes is crucial for many biotechnological applications. The recently described DNA binding domain of the transcription activator-like effectors (TALEs) from Xanthomonas consists of a series of repeats arranged in tandem, each repeat binding a nucleotide of the target sequence. We present here a strategy for engineering of TALE proteins with novel DNA binding specificities based on the 17.5 repeat-containing AvrBs3 TALE as a scaffold. For each of the 17 full repeats, four module types were generated, each with a distinct base preference. Using this set of 68 repeat modules, recognition domains for any 17 nucleotide DNA target sequence of choice can be constructed by assembling selected modules in a defined linear order. Assembly is performed in two successive one-pot cloning steps using the Golden Gate cloning method that allows seamless fusion of multiple DNA fragments. Applying this strategy, we assembled designer TALEs with new target specificities and tested their function in vivo. PMID:21625552

Forty wild canids including 31 golden jackals (Canis aureus Linné, 1758) and 9 red foxes (Vulpes vulpes Linné, 1758) collected between 2008 and 2011 in the northeast, northwest and center of Tunisia were necropsied and examined for intestinal helminth parasites. All jackals and foxes were found infected with a prevalence rate of 95% for cestodes, 82.5% for nematodes and 7.5% for acanthocephalans. A total of twelve helminth species were recorded in red foxes: cestodes, Dipylidium caninum (55.6%), Diplopylidium noelleri (55.6%), Mesocestoïdes lineatus (55.6%), Mesocestoïdes litteratus (33%), Mesocestoïdes corti (22%); nematodes, Ancylostoma caninum (11%), Uncinaria stenocephala (44%), Spirura rytipleurites (11%), Trichuris vulpis (33%), Pterygodermatites affinis (67%), Oxynema linstowi (33%) and the acanthocephalan Macracanthorhynchus hirudinaceus (22%). The fifteen recovered helminth species in jackals were Echinococcus granulosus (9.7%), D. caninum (16%), D. noelleri (16%), M. lineatus (74%), M. litteratus (23%), M. corti (12.9%), Taenia pisiformis (3.2%), Taenia spp. (19%), Toxocara canis (16%), Toxascaris leonina (6.5%), A. caninum (9.7%), U. stenocephala (68%), P. affinis (6.5%), O. linstowi (3.2%) and Macracanthorhynchus hirudinaceus (3.2%). This is the first report on the presence of P. affinis, D. noelleri and O. linstowi in Tunisia. E. granulosus was found in young jackals, aged less than 4 years old, with a higher abundance in females (8.9 worms). M. lineatus presented the highest mean intensity of 231.86 and 108.8 tapeworms respectively in jackals and foxes. Canids from the northwest region had the highest prevalence (77.5%) and highest intensity (243.7) of helminth species compared to those from the northeast and central areas. U. stenocephala and O. linstowi had the highest mean intensity for nematodes in both jackals and foxes at 14.3 and 88 worms respectively. PMID:24938826

[Prevalence of pectinate ligament dysplasia in golden retrievers in Switzerland].  

PubMed

The prevalence of pectinate ligament dysplasia was evaluated in a prospective multi-center examination of randomly selected Golden retrievers of variable sex and age. The examinations were carried out by qualified veterinary ophthalmologists between May 1 and May 31, 2013. A total of 92 dogs (29 male and 62 female dogs) were examined. The dogs were between 6 months and 14 years old (4.53 ± 3.02 years). Gonioscopy was performed under topical anesthesia using a Koeppe lens and a hand-held slit lamp with ? 10-x magnification. Four quadrants (dorsal, lateral, medial, ventral) were examined in each eye. For each quadrant a score between 3 (normal) and 0 (grossly abnormal) was assigned. The average total score for all quadrants was 2.14 ± 0.95. The width of the drainage angle W was 2.29 ± 0.88, while the score for mesodermal dysplasia MD was 1.98 ± 0.98. There was no significant difference between left and right eyes, however, a significant difference was found between female and male dogs, as well as between young dogs and older dogs. The width of the drainage angle decreased with age and the degree of mesodermal dysplasia increased. Female dogs had lower total scores compared to male dogs and the ventral and lateral quadrants had significantly lower scores than the other quadrants. In conclusion, 52/92 (56.5 %) showed signs of Pectinate ligament dysplasia and would have to be excluded from a breeding program according to the guidelines of the European College of Veterinary Ophthalmologists.

A pilot golden eagle population study in the Altamont Pass Wind Resource Area, California  

SciTech Connect

Orloff and Flannery (1992) estimated that several hundred reports are annually killed by turbine collisions, wire strikes, and electrocutions at the Altamont Pass Wind Resource Area (WRA). The most common fatalities were those of red-tailed hawks (Buteo jamaicensis), American kestrels (Falco sparvatius), and golden eagles (Aquila chrysaetos), with lesser numbers of turkey vultures (Cathartes aura), common ravens (Corvus corax), bam owls (Tyto alba), and others. Among the species of raptors killed at Altamont Pass, the one whose local population is most likely to be impacted is the golden eagle. Besides its being less abundant than the others, the breeding and recruitment rates of golden eagles are naturally slow, increasing their susceptibility to decline as a result of mortality influences. The golden eagle is a species afforded special federal protection because of its inclusion within the Bald Eagle Protection Act as amended in 1963. There are no provisions within the Act which would allow the killing ``taking`` of golden eagles by WRA structures. This report details the results of field studies conducted during 19941. The primary purpose of the investigation is to lay the groundwork for determining whether or not turbine strikes and other hazards related to energy at Altamont Pass may be expected to affect golden eagles on a population basis. We also seek an understanding of the physical and biotic circumstances which attract golden eagles to the WRA within the context of the surrounding landscape and the conditions under which they are killed by wind turbines. Such knowledge may suggest turbine-related or habitat modifications that would result in a lower incidence of eagle mortality.

Evaluation of amitrole (aminotriazole) for potential carcinogenicity in orally dosed rats, mice, and golden hamsters  

SciTech Connect

Amitrole was evaluated for carcinogenic potential in lifespan studies on Wistar rats, NMRI mice, and golden hamsters. At the start of the studies the animals were 6 weeks old. Amitrole was administered, mixed with pulverized chow, at dietary concentrations of 0, 1, 10, and 100 micrograms/g (ppm). Each treated group and control group consisted of 75 male and 75 female rats and mice and of 76 male and 76 female golden hamsters. Additional animals were used to evaluate the functional state of the thyroid. Somewhat lower body weights, slightly reduced survival times, and transient effects on thyroid function were observed in golden hamsters at 100 ppm. In mice, a slight increase in pituitary gland hyperemias was seen at 100 ppm; also an effect on thyroid function usually occurred at the same concentration. In rats, a very large number of cystic dilatations of follicles in the thyroid at 100 ppm and a dose-unrelated increase in hemorrhages and hyperemias in the pituitary gland were indicative of an effect of amitrole on these organs. The strongest effect of amitrole on thyroid function, as compared to golden hamsters and mice, was seen in rats at 100 ppm. At this concentration a highly increased number of thyroid and pituitary gland tumors was observed in rats. In golden hamsters and mice, no tumor induction was seen.

A study on the practical applicability of the rule of golden rectangle in dental aesthetics.  

PubMed

Maxillary central incisors are of critical value in the aesthetics of a smile. The Golden Rectangle ratio concept may play an important role in selecting the optimum width and length of this tooth. The aim of the study was to investigate the existence of this ratio among individuals with natural dentition and to validate its role in aesthetic oral rehabilitation. The clinical crown length of the maxillary left central incisor (CI) and combined crown width of the maxillary left and right CI of 70 subjects were measured. The crown width to crown length ratio was calculated and compared with the Golden Rectangle ratio and statistically analysed. Eighty percent of the subjects varied within 2 standard deviations of the ratio of 1.618. No statistically significant influence of gender on the ratio was observed. Golden rectangle was found to have a significant relationship with aesthetic appearance of maxillary central incisors. PMID:21780732

Golden carbon nanotubes as multimodal photoacoustic and photothermal high-contrast molecular agents  

NASA Astrophysics Data System (ADS)

Carbon nanotubes have shown promise as contrast agents for photoacoustic and photothermal imaging of tumours and infections because they offer high resolution and allow deep tissue imaging. However, in vivo applications have been limited by the relatively low absorption displayed by nanotubes at near-infrared wavelengths and concerns over toxicity. Here, we show that gold-plated carbon nanotubes-termed golden carbon nanotubes-can be used as photoacoustic and photothermal contrast agents with enhanced near-infrared contrast (~102-fold) for targeting lymphatic vessels in mice using extremely low laser fluence levels of a few mJ cm-2. Antibody-conjugated golden carbon nanotubes were used to map the lymphatic endothelial receptor, and preliminary in vitro viability tests show golden carbon nanotubes have minimal toxicity. This new nanomaterial could be an effective alternative to existing nanoparticles and fluorescent labels for non-invasive targeted imaging of molecular structures in vivo.

The chemical oceanographic consequences of environmental restoration projects in the Golden Horn estuary (Marmara Sea, Turkey).  

PubMed

The input of industrial and domestic waste to the horizontal circulation in the Golden Horn Estuary of Marmara Sea has resulted in one of the most polluted estuaries in the past. Consequently, the dissolved oxygen concentrations in both the surface and bottom waters decreased toward to the estuary head during 1998-2005. In contrast, the total suspended solids content of the surface water decreased toward to the estuary mouth. However, construction of the operational collector system surrounding the estuary during the process of rehabilitation projects, combined with the opening of the middle pontoons of the Valide Sultan Bridge, resulted in gradually improved water quality of the estuary with a concomitant decrease in pollution. However, phytoplankton blooms and eutrophication persist especially in the innermost part of the Golden Horn in 2005. The region from the estuary mouth up to Camialti has a dynamic structure, and sufficient circulation seemingly occurs in this part of the Golden Horn. PMID:19353286

A discriminant function analysis of specimen measurements separates 96% of two forms of Lesser Golden Plover in breeding plumage, previously described as subspecies. The forms breed sympatrically in northwest Alaska and are not isolated by habitat, but the incidence of specimens phenotypically intermediate between the two forms is no higher there than in areas of allopatry.

Do male golden egg bugs carry eggs they have fertilized? A microsatellite analysis  

Microsoft Academic Search

In the golden egg bug, Phyllomorpha laciniata (Heteroptera, Coreidae), both males and females carry eggs on their back. Although females cannot carry their own eggs, males may carry eggs that they have fertilized. If males carry eggs they have fertilized, their behavior may be interpreted as paternal care. In this article, we provide genetic data for paternity assignment of eggs

Radioactivity levels in mussels and sediments of the Golden Horn by the Bosphorus Strait, Marmara Sea.

The Golden Horn is an estuary located in the center of ?stanbul receiving freshwater discharges from two creeks and connecting to the Bosphorus Strait. Activity concentrations of natural and artificial radionuclides were determined in mussels (Mytilus galloprovincialis) and sediments from the Golden Horn sampled in February 2012. Mean activity concentrations of (137)Cs, (40)K, (226)Ra, (228)Ra, (210)Po and (210)Pb in the mussels were determined at 1.03±0.23, 389±41.6, 2.61±1.23, not detected (ND), 91.96±37.88 and 11.48±4.85 Bq kg(-1), respectively. In sediments, it was observed that (137)Cs, (40)K, (226)Ra, (228)Ra, (210)Po and (210)Pb activity concentrations in<63 ?m particle fraction of sediment were generally higher than those determined in mussels. Po-210 and (210)Po/(210)Pb ratios in mussels from the Golden Horn were much lower than in mussels from other coastal regions and this was related to low plankton productivity and eutrophication of the Golden Horn.

The geology and mineralisation at the Golden Pride gold deposit, Nzega Greenstone Belt, Tanzania  

NASA Astrophysics Data System (ADS)

The Golden Pride gold deposit (˜3 Moz) is located in the central part of the Nzega Greenstone Belt at the southern margin of the Lake Victoria Goldfields in Tanzania. It represents an inferred Late Archaean, orogenic gold deposit and is hosted in intensely deformed meta-sedimentary rocks in the hanging wall of the approximately E-W striking Golden Pride Shear Zone. The hanging-wall sequence also includes felsic (quartz porphyritic) to mafic (lamprophyric) intrusions, as well as banded iron formations. Hydrothermal alteration phases associated with mineralisation are dominated by sericite and chlorite. Two main ore types can be distinguished, chlorite and silica ore, both occupying dilational sites and structural intersections in the hanging wall of the main shear zone. Sulphide minerals in both ore types include pyrrhotite, arsenopyrite, pyrite and accessory sphalerite, galena, sulphosalts and Ni-Co-Bi sulphides. Gold and tellurides are late in the paragenetic sequence and associated with a secondary phase of pyrrhotite deposition. Sulphur isotope compositions range from -6 to 7 per mil and are interpreted to reflect contributions from two distinct sources to the mineralising fluids in the Golden Pride gold deposit. A redox change, potentially induced by the intrusion of mafic melts, together with structural elements in the hanging wall of the Golden Pride Shear Zone, are interpreted to be the main controls on gold mineralisation in this deposit.

Genetic diversity of a newly established population of golden eagles on the Channel Islands, California  

USGS Publications Warehouse

Gene flow can have profound effects on the genetic diversity of a founding population depending on the number and relationship among colonizers and the duration of the colonization event. Here we used data from nuclear microsatellite and mitochondrial DNA control region loci to assess genetic diversity in golden eagles of the recently colonized Channel Islands, California. Genetic diversity in the Channel Island population was low, similar to signatures observed for other recent colonizing island populations. Differences in levels of genetic diversity and structure observed between mainland California and the islands suggests that few individuals were involved in the initial founding event, and may have comprised a family group. The spatial genetic structure observed between Channel Island and mainland California golden eagle populations across marker types, and genetic signature of population decline observed for the Channel Island population, suggest a single or relatively quick colonization event. Polarity in gene flow estimates based on mtDNA confirm an initial colonization of the Channel Islands by mainland golden eagles, but estimates from microsatellite data suggest that golden eagles on the islands were dispersing more recently to the mainland, possibly after reaching the carrying capacity of the island system. These results illustrate the strength of founding events on the genetic diversity of a population, and confirm that changes to genetic diversity can occur within just a few generations.

Parasite community interactions: Trypanosoma cruzi and intestinal helminths infecting wild golden lion tamarins Leontopithecus rosalia and golden-headed lion tamarins L. chrysomelas (Callitrichidae, L., 1766).  

PubMed

The parasite prevalence and infection intensity in primate wild populations can be affected by many variables linked to host and/or parasite ecology or either to interparasite competition/mutualism. In this study, we tested how host sex, age, and place of origin, as well parasitic concomitant infections affect the structure of golden lion and golden-headed lion tamarins parasite community, considering Trypanosoma cruzi and intestinal helminths infection in these primates. A total of 206 tamarins from two Atlantic Coastal rain forest areas in Brazil were tested during 4 years for prevalence of T. cruzi infection and helminth prevalence. Three intestinal helminth groups showed high prevalences in both tamarin species: Prosthenorchis sp., Spiruridae, and Trichostrongylidae. An association between presence of T. cruzi infection and higher intestinal helminth prevalence was found in both tamarin species. Two explanations for this association seem to be plausible: (1) lower helminth-linked mortality rates in T. cruzi-infected tamarins and (2) lower elimination rates of helminths in such tamarins. A higher frequency of T. cruzi-positive blood cultures was significantly correlated to female tamarins and to the presence of Trichostrongylidae infection. The possibility of an increase in the transmissibility of T. cruzi and the three analyzed helminths in lion tamarins with concomitant infections is discussed. PMID:17676342

Presence of Leishmania and Brucella species in the golden jackal Canis aureus in Serbia.  

PubMed

The golden jackal Canis aureus occurs in south-eastern Europe, Asia, the Middle East, the Caucasus, and Africa. In Serbia, jackals neared extinction; however, during the last 30 years, the species started to spread quickly and to increase in number. Few studies in the past have revealed their potential role as carriers of zoonotic diseases. Animal samples were collected over a three-year period (01/2010-02/2013) from 12 sites all over Serbia. Of the tissue samples collected, spleen was chosen as the tissue to proceed; all samples were tested for Leishmania species and Brucella species by real-time PCR. Of the 216 samples collected, 15 (6.9%) were positive for Leishmania species, while four (1.9%) were positive for B. canis. The potential epidemiologic role of the golden jackal in carrying and dispersing zoonotic diseases in Serbia should be taken under consideration when applying surveillance monitoring schemes.

Golden Rule of Radiation Hardness: a Study of Strain Effect on Controlled Radiation Damage  

NASA Astrophysics Data System (ADS)

Stain is widely presented in microstructures. Strain effect to radiation hardness is critical in understanding and engineering nano-materials. Here we studied the strain effect on the controlled radiation damage in monolayer hexagonal boron nitride (h-BN) through ab initio density functional theory calculations. We observed a general behavior of reduction in the radiation hardness by the strain, for both B-vacancy and N-vacancy configurations, in both compressive and tensive strain states, at the directions of zigzag, armchair and bi-axial. We proposed a golden rule of the radiation hardness states that any effort adding energy to the system will reduce the radiation hardness. Such golden rule of radiation hardness could be widely applied to material design and engineering for those devices working in irradiation-enrich environments, for example, electronic and optoelectronic devices in outer space.

Pneumonitis in Syrian golden hamsters (Mesocricetus auratus) infected with Rio Mamoré virus (family Bunyaviridae, genus Hantavirus).  

PubMed

Rio Mamoré virus is an etiological agent of hantavirus pulmonary syndrome in South America. The purpose of this study was to determine whether Rio Mamoré virus strain HTN-007 in Syrian golden hamsters is pathogenic. None of 37 adult hamsters infected by intramuscular injection of HTN-007, including 10 animals killed on Day 42 or 43 post-inoculation, exhibited any symptom of disease. Histological abnormalities included severe or moderately severe pneumonitis in 6 (46.2%) of the 13 animals killed on Day 7 or 10 post-inoculation. The primary target of infection in lung was the endothelium of the microvasculature. Collectively, these results indicate that Rio Mamoré virus strain HTN-007 in adult Syrian golden hamsters can cause a nonlethal disease that is pathologically similar to hantavirus pulmonary syndrome.

Rock Magnetic and Paleointensity Study of Eastern California's ~83 Ma Golden Bear and Coso Dikes  

NASA Astrophysics Data System (ADS)

Extraordinary intermediate-composition (Kspar +/- quartz andesite porphyry) dikes are coincident with the end of Sierra Nevada magmatism and crop out on both the east and the west sides of Owens Valley, but offset dextrally by >60 km. If this offset represents ancient (possibly Cretaceous) strike-slip partitioning of Pacific-North America plate boundary strain, then at least one of the south- and east-sited Coso dikes might be expected to be paleomagnetically "identical" to its presumed paleo-contiguous, north- and west-sited Golden Bear partner. Accompanying a directional study by Pluhar and colleagues at CSU-Fresno, we are characterizing magnetic mineralogy, fabric, and thermal lability of Coso dikes and the Golden Bear dike. We are also applying the pTRM difference multi-specimen paleointensity technique to these samples, testing for across-Owens Valley correlation.

Golden Ratio estimate of success probability based on one and only sample  

E-print Network

This paper proposes iterative Bayesian method to estimate success probability based on unique sample. The procedure is replacing the distribution characteristic of prior with Bayes estimate on the every iteration until they coincide. Iterative Bayes estimate is generally independent of hyperparameters. For binomial, Poisson, exponential and normal model, iterative limit is shown to be MLE in case the expectation of conjugate prior is replaced respectively. Particularly, suppose success appears in one and only trial, while the mode of triangle prior is replaced iterative Bayesian method gives $1/\\phi \\approx 0.618$ ($\\phi$ is Golden Ratio) as the estimate of success probability $p$, this result reveals the truth of Golden Ratio from the point of statistics. Furthermore, under triangle prior the unique sample $X$ from binomial model $B(n,p)$ is considered. Existence and uniqueness of iterative Bayes estimator $\\hat{p}_{IB}$ for parameter $p$ is given.

Mating patterns in the golden lion tamarin (Leontopithecus rosalia): continuous receptivity and concealed estrus.  

PubMed

Sociosexual behavior was monitored on a daily basis for 3 months in 5 pairs of golden lion tamarins (Leontopithecus rosalia). Urine samples were collected daily from each female and urinary estrogen cycles were determined by radioimmunoassay. Mounts and copulations were observed during all phases of the estrogen cycle. Peaks or regular cycles in sexual behavior were not documented. There were no significant changes in affiliative behavior by females or males that were associated with changes in urinary estrogen values. A negative relationship between pair bond duration and frequency of sexual interactions was observed: newly established pairs exhibited 2-6 times more frequent sexual behavior than a long-established pair. The lack of a conspicuous sexual signal in female golden lion tamarins may be related to a pattern of continuous sexual receptivity. Both reproductive patterns, concealed estrus and continuous receptivity, are explicable in relation to either monogamous or polyandrous mating systems. PMID:3143650

Echinococcus multilocularis and Trichinella spiralis in golden jackals (Canis aureus) of Hungary.  

PubMed

Over the last decades the distribution area of the golden jackal (Canis aureus) has increased significantly in Europe, particularly in the Balkan Peninsula and in Central Europe. Vagrant individuals were described in many European countries. Herein, we report Echinococcus multilocularis (total worm count: 412) and Trichinella spiralis (101 larvae/g for muscles of the lower forelimb) infections in two golden jackals shot in Hungary. It is a new host record of E. multilocularis and T. spiralis in Europe and Hungary, respectively. As jackals migrate for long distances through natural ecological corridors (e.g., river valleys), they may play a significant role in the long distance spread of zoonotic parasites into non-endemic areas of Europe. Therefore, monitoring zoonotic parasites in this host species can be recommended in the European Union. PMID:23688637

Anal. 16, No. 7, 1377-1390 (2006)]. The FGR is a key condition in a study of the asymptotic dynamics of trapped solitons.

Assessment of Facial Golden Proportions among North Maharashtri-an Population  

PubMed Central

Background: Divine Proportion in Orthodontics and Prosthodontics has always been intriguing. This was applied to the North Maharashtrian population to evaluate the relationship between facial esthetics and the golden proportions. Materials & Methods: Facial proportions were assessed by examining photographs of sum total of 300 subjects of North Maharashtrian population. Young adults with a skeletal and dental Class 1 occlusion, competent lips, and balanced facial proportion were selected. Photographic prints were taken and manually parameters were plotted and analysis was done. Results: The measurements of anterior facial height showed proportionality with the total facial height. The values showed shorter lower anterior facial height and deviation of facial width parameters from the divine proportion indicating small mouth, nose, and narrow-set eyes with respect to the inter-temporal width. Conclusion: There is soft-tissue facial balance of North Maharashtrian population in comparison with the golden proportion. However, certain parameters show some deviation from the divine proportion.. How to cite this article: Sunilkumar L N, Jadhav K S, Nazirkar G, Singh S, Nagmode P S, Ali F M.

Novel function of lipids as a pheromone from the Harderian gland of golden hamster  

PubMed Central

Sexual diversity of ADG in Harderian gland of golden hamster was demonstrated on TLC. Female ADG contained iso- and anteiso-branched acyl and alkyl components, but male ADG contained only straight chain ones, which suggested the hormonal control of the expression of acyl-CoA dehydrogenases in the catabolism of BCAA. Acyl-CoA dehydrogenases were not expressed in the absence of testosterone, and then isovaleryl-CoA, 2-methylbutyryl-CoA, and isobutyryl-CoA accumulated, and acted as primers for the synthesis of iso- and anteiso-branched fatty acids. The incorporation of [U-14C] leucine into lipids was monitored by TLC. The cholesterol fraction was labeled in males but not in female, which means that cholesterol was not produced from BCAA in female gland due to the lack of expression of acyl-CoA dehydrogenases. We monitored the behavior of male hamsters toward female gland lipids, and found slightly greater attractiveness in female ones than that in male ones although the difference was not significant. Considering the lifestyle of golden hamster in nature, we propose a hypothesis that the lipids from the Harderian gland of golden hamster serve as a pheromone to declare their territory and to seek the mate with good congeniality.

Ontogenetic development of digestive functionality in golden pompano Trachinotus ovatus (Linnaeus 1758).  

PubMed

Ontogenetic development of the digestive system in golden pompano (Trachinotus ovatus, Linnaeus 1758) larvae was histologically and enzymatically studied from hatch to 32 day post-hatch (DPH). The development of digestive system in golden pompano can be divided into three phases: phase I starting from hatching and ending at the onset of exogenous feeding; phase II starting from first feeding (3 DPH) and finishing at the formation of gastric glands; and phase III starting from the appearance of gastric glands on 15 DPH and continuing onward. The specific activities of trypsin, amylase, and lipase increased sharply from the onset of first feeding to 5-7 DPH, followed by irregular fluctuations. Toward the end of this study, the specific activities of trypsin and amylase showed a declining trend, while the lipase activity remained at similar levels as it was at 5 DPH. The specific activity of pepsin was first detected on 15 DPH and increased with fish age. The dynamics of digestive enzymes corresponded to the structural development of the digestive system. The enzyme activities tend to be stable after the formation of the gastric glands in fish stomach on 15 DPH. The composition of digestive enzymes in larval pompano indicates that fish are able to digest protein, lipid and carbohydrate at early developmental stages. Weaning of larval pompano is recommended from 15 DPH onward. Results of the present study lead to a better understanding of the ontogeny of golden pompano during the larval stage and provide a guide to feeding and weaning of this economically important fish in hatcheries.

Development block of golden hamster ICSI embryos is associated with decreased expression of HDAC1, HSPA1A and MYC.  

PubMed

We have investigated the mechanism for embryo development block in vitro and to improve the development rate of golden hamster embryos in vitro. Intracytoplasmic sperm injection (ICSI) technique was used to produce golden hamster ICSI embryos. The changes in the histone acetylation and the expression of histone deacetylase and related genes were analyzed by immunocytochemical staining and real-time PCR both in golden hamster in vivo embryos and in ICSI embryos. Aged oocytes significantly increased the oocyte spontaneous activation rate. In vitro cultured ICSI embryos suffered from severe development block in M199TE medium. Expression of histone deacetylase 1 (HDAC1) was significantly decreased in the nuclei of the arrested ICSI 2-cell embryos, and its nuclear and cytoplasmic expression pattern was also markedly altered. The acetylation level of H4K5, however, was not significantly changed between golden hamster in vivo embryos and ICSI embryos. HSPA1A and MYC, the marker genes for zygotic genome activation (ZGA), were transcriptionally decreased in arrested ICSI 2-cell embryos. Transcription of HDAC1 was also downregulated in these embryos, whereas the mRNA expression of the proapoptotic gene, BAX, was not changed. These results indicate that the golden hamster ICSI embryo development block during ZGA is associated with decreased nuclear expression and altered expression of HDAC1. HSPA1A, MYC, and HDAC1 mRNA levels, which decrease, resulting in ZGA failure. PMID:24890342

Search for the Golden Moon Bear: Using Readerâs Theater to Teach Science  

NSDL National Science Digital Library

Readerâs theater is an activity in which students, while reading directly from scripts, are able to tell a story in its most entertaining form. Typically, teachers create or purchase premade scripts of stories, and students focus on reading those scripts in a fluent and expressive manner. However, in the lesson presented here, students turn the book, Search for the Golden Bear Moon: Science and Adventure in the Asian Tropics by Sy Montgomery into a readerâs theater script themselves. This article describes how students act out this genetics-based story to strengthen their language skills and reinforce science concepts in the process.

Subspecies-informative SNP assays for evaluating introgression between native golden trout and introduced rainbow trout.  

PubMed

We characterize 20 single nucleotide polymorphism assays for evaluating hybridization between native golden trout subspecies (Oncorhynchus mykiss aguabonita and O. m. whitei) and introduced rainbow trout strains. These assays utilize the 5'-nuclease reaction, facilitating high-throughput genotyping of many individuals and making them useful in quantifying and monitoring introgression and potentially applicable to studies of other O. mykiss groups. Minor allele frequency differentials (?q) among native and introduced rainbow groups ranged from 0 to 1, with an average differential of 0.75 for both subspecies aguabonita and whitei relative to the hatchery rainbow trout strain.

The energy level spacing for two harmonic oscillators with golden mean ratio of frequencies  

NASA Astrophysics Data System (ADS)

Berry and Tabor discussed, among other things, a beautiful problem about the energy level spacing distribution for a system of two harmonic oscillators. They gave some interesting theoretical arguments which show that there is no level clustering for generic harmonic oscillators, and various numerical experiments were exposed and discussed. But the main question they posed about the existence of the limit distribution of the level spacing remained open. The present paper discusses this question in the case when the ratio of the frequencies is the golden mean ?=(?5-1)/2. The approach enables one to study the generic case of the frequency ratio as well, which is done elsewhere.

Lead contamination of golden eagles Aquila chrysaetos within the range of the California condor Gymnogyps californianus  

USGS Publications Warehouse

Blood samples were taken from 66 golden eagles from June 1985 to January 1986 and analyzed for their lead content. Thirty-nine percent had blood lead levels greater than 0.2 ppm, indicating exposure to environmental lead. Within the exposed group, 3 had blood levels exceeding 0.6 ppm and one exceeded 1.0 ppm. These data suggest that lead, probably in the form of shot, bullets, or bullet fragments, poses a hazard to scavenging birds within the range of the California condor.

Short-term oscillations in avian molt intensity: Evidence from the golden eagle Aquila chrysaetos

From a year-long study of molt in the golden eagle Aquila chrysaetos, we recorded 2069 contour feathers replaced in 137 d (6 May-19 September). Very few contour feathers were lost outside this period. From precise daily counts of feathers lost, and using time series analysis, we identified short-term fluctuations (i.e., 19-d subcycles) around a midsummer peak (i.e., a left-skewed normal distribution). Because these subcycles have never before been reported and because the physiological basis for many aspects of avian molt is poorly known, we offer only hypothetical explanations for the controls responsible for the subcycles. ??

Short-day exposure eliminates the LH response to naloxone in golden hamsters.  

PubMed

Short-day-induced testicular regression in golden hamsters is accompanied by changes in opiatergic control of LH release. Serum LH in long-day-exposed hamsters is elevated by subcutaneous injections of naloxone. By day 42 of short-day exposure, naloxone is unable to stimulate LH secretion; responsiveness to naloxone is restored after reexposure to long days. The change in response to naloxone may reflect a loss of opiate regulation of LH release; an alternative, but not mutually exclusive, hypothesis is that additional opiate-independent mechanisms inhibit LH despite the blockade of opiate LH inhibition by naloxone.

First molecular evidence of Hepatozoon canis infection in red foxes and golden jackals from Hungary  

PubMed Central

Background Recently, Hepatozoon canis infection has been detected among shepherd, hunting and stray dogs in the southern part of Hungary, which is considered to be free of Rhipicephalus sanguineus sensu lato and close to the border with Croatia. The aim of this study was to acquire information on the possibility that red foxes and/or golden jackals could play a role in the appearance and spread of H. canis in Hungary. Methods A conventional PCR was used to amplify a 666 bp long fragment of the Hepatozoon 18S rRNA gene from blood samples collected from 334 foxes shot in 231 locations in 16 counties and 15 golden jackals shot in 9 locations in two southwestern counties close to Croatia. A second PCR assay was performed in some of the samples positive by the first PCR to amplify a larger segment (approximately 1500 bp) of the 18S rRNA gene of Hepatozoon spp. for further phylogenetic analysis. Results Hepatozoon infection was detected in canids shot in 30 locations and 9 counties. Altogether 26 foxes (8.0%, 95% CI: 5-11%) and 9 jackals (60%, 95% CI: 33-81%) were PCR positive. Hepatozoon canis sequences were obtained from 12 foxes and 7 jackals. DNA sequences from 16 animals were 99-100% similar to H. canis from Croatian foxes or dogs while two of the sequences were 99% similar to an Italian fox. Half (13/26) of the infected red foxes and all golden jackals were shot in the two southwestern counties. Conclusions This is the first report on molecular evidence of H. canis in red foxes (Vulpes vulpes) and golden jackals (Canis aureus) from Hungary, which is considered free from the tick vector of H. canis, R. sanguineus. Although no R. sanguineus sensu lato had been found on infected or non-infected wild canids, the detection of authochnous canine hepatozoonosis in Hungary might imply that the range of R. sanguineus sensu lato has reached this country.

A CPV module containing 30 III-V multijunction cells was operated on-sun for one year in Golden, Colorado. Each cell was characterized prior to and following exposure. A module power degradation of 10% was observed and found to be a result as an overall decrease in cell short circuit current and the presence of at least one shunted cell. A positive correlation between initial shunt current and an increase in shunt current following exposure was also found. Cell exfoliation was also observed and found to be coincident with the presence of water and/or charring of the cell package due to an off-sun event.

A novel laboratory anticestode assay was developed using Hymenolepis diminuta in the hamster. The commercial anticestode compounds, praziquantel, bunamidine, and niclosamide were active against patent infections of Hymenolepis diminuta in golden hamsters (Mesocricetus auratus) when given orally at 3.125, 100, and 200 mg/kg, respectively. The gastrointestinal nematode anthelmintics, cambendazole and mebendazole, were active at 50 mg/kg. Rafoxanide (fasciolicide) was active at 25 mg/kg, the lowest level tested. The coccidiostat, nicarbazin, was active at experimental levels (800 mg/kg and up). The anthelmintic-ectoparasiticide (endectocide), ivermectin, was inactive against the tapeworm at 0.5 mg/kg, as expected. PMID:15357098

The influence of weather on Golden Eagle migration in northwestern Montana  

USGS Publications Warehouse

We analyzed the influence of 17 weather factors on migrating Golden Eagles (Aquila chrysaetos) near the Continental Divide in Glacier National Park, Montana, U.S.A. Local weather measurements were recorded at automated stations on the flanks of two peaks within the migration path. During a total of 506 hr of observation, the yearly number of Golden Eagles in autumn counts (1994-96) averaged 1973; spring counts (1995 and 1996) averaged 605 eagles. Mean passage rates (eagles/hr) were 16.5 in autumn and 8.2 in spring. Maximum rates were 137 in autumn and 67 in spring. Using generalized linear modeling, we tested for the effects of weather factors on the number of eagles counted. In the autumn model, the number of eagles increased with increasing air temperature, rising barometric pressure, decreasing relative humidity, and interactions among those factors. In the spring model, the number of eagles increased with increasing wind speed, barometric pressure, and the interaction between these factors. Our data suggest that a complex interaction among weather factors influenced the number of eagles passing on a given day. We hypothesize that in complex landscapes with high topographic relief, such as Glacier National Park, numerous weather factors produce different daily combinations to which migrating eagles respond opportunistically. ?? 2001 The Raptor Research Foundation, Inc.

Predators as prey at a Golden Eagle Aquila chrysaetos eyrie in Mongolia  

USGS Publications Warehouse

Although golden eagles (Aquila chrysaetos) have for decades been known to occasionally take large or dangerous quarry, the capturing of such was generally believed to be rare and/or the act of starved birds. This report provides details of an exceptional diet at a golden eagle eyrie in eastern Mongolia with unquantified notes on the occurrence of foxes at other eyries in Mongolia. Most of the prey we recorded were unusual, including 1 raven (Corvus corax), 3 demoiselle cranes (Anthropoides virgo), 1 upland buzzard (Buteo hemilasius), 3 owls, 27 foxes, and 11 Mongolian gazelles. Some numerical comparisons are of interest. Our value for gazelle calves (10 minimum count, 1997) represents 13% of 78 prey items and at least one adult was also present. Our total of only 15 hares (Lepus tolai) and 4 marmots (Marmota sibirica) compared to 27 foxes suggests not so much a preference for foxes, but rather that populations of more normal prey were probably depressed at this site. Unusual prey represented 65% of the diet at this eyrie.

GoldenBraid: An Iterative Cloning System for Standardized Assembly of Reusable Genetic Modules  

PubMed Central

Synthetic Biology requires efficient and versatile DNA assembly systems to facilitate the building of new genetic modules/pathways from basic DNA parts in a standardized way. Here we present GoldenBraid (GB), a standardized assembly system based on type IIS restriction enzymes that allows the indefinite growth of reusable gene modules made of standardized DNA pieces. The GB system consists of a set of four destination plasmids (pDGBs) designed to incorporate multipartite assemblies made of standard DNA parts and to combine them binarily to build increasingly complex multigene constructs. The relative position of type IIS restriction sites inside pDGB vectors introduces a double loop (“braid”) topology in the cloning strategy that allows the indefinite growth of composite parts through the succession of iterative assembling steps, while the overall simplicity of the system is maintained. We propose the use of GoldenBraid as an assembly standard for Plant Synthetic Biology. For this purpose we have GB-adapted a set of binary plasmids for A. tumefaciens-mediated plant transformation. Fast GB-engineering of several multigene T-DNAs, including two alternative modules made of five reusable devices each, and comprising a total of 19 basic parts are also described. PMID:21750718

Functional Integral Representations and Golden-Thompson Inequalities in Boson-Fermion Systems  

NASA Astrophysics Data System (ADS)

For a general class of boson-fermion Hamiltonians H acting in the tensor product Hilbert space L2(?n) ? ?(?r) of L2(?n) and the fermion Fock space ?(?r) over ?r(n, r ? ?), we establish, in terms of an n-dimensional conditional oscillator measure, a functional integral representation for the trace Tr(F ? zNfe-tH)(F ? L?(?n), z ? ??{0}, t > 0), where Nf is the fermion number operator on ?(?r). We prove a Golden-Thompson type inequality for |Tr(F ? zNfe-tH)|. Also we discuss applications to a model in supersymmetric quantum mechanics and present an improved version of the Golden-Thompson inequality in supersymmetric quantum mechanics given by Klimek and Lesniewski ([Lett. Math. Phys.21 (1991) 237-244]). An upper bound for the number of the supersymmetric states is given as well as a sufficient condition for the spontaneous supersymmetry breaking. Moreover, we derive a functional integral representation for the analytical index of a Dirac type operator on ?n (Witten index) associated with the supersymmetric quantum mechanical model.

Pilot Inventory of Mammals, Reptiles, and Amphibians, Golden Gate National Recreation Area, California, 1990-1997  

USGS Publications Warehouse

The United States Geological Survey Golden Gate Field Station conducted a baseline inventory of terrestrial vertebrates within the Golden Gate National Recreation Area (GGNRA), Marin, San Francisco, and San Mateo Counties, California between 1990 and 1997. We established 456 permanent study plots in 6 major park habitats, including grassland, coastal scrub, riparian woodland, coastal wetland, broad-leaved evergreen forest, and needle-leaved evergreen forest. We tested multiple inventory methods, including live traps, track plate stations, and artificial cover boards, across all years and habitats. In most years, sampling occurred in 3-4 primary sampling sessions between July and September. In 1994, additional sampling occurred in February and May in conjunction with an assessment of Hantavirus exposure in deer mice (Peromyscus maniculatus). Overall, we detected 32 mammal, 14 reptile, and 6 amphibian species during 25,222 trap-nights of effort. The deer mouse-the most abundant species detected--accounted for 67% of total captures. We detected the Federal Endangered salt marsh harvest mouse (Reithrodontomys raviventris) at one coastal wetland plot in 1992. This project represents the first phase in the development of a comprehensive terrestrial vertebrate inventory and monitoring program for GGNRA. This report summarizes data on relative abundance, frequency of occurrence, distribution across habitat types, and trap success for terrestrial vertebrates detected during this 7-year effort. It includes comprehensive descriptions of the inventory methods and sampling strategies employed during this survey and is intended to help guide the park in the implementation of future longterm ecological monitoring programs.

The United States Geological Survey Golden Gate Field Station conducted a baseline inventory of terrestrial vertebrates within the Golden Gate National Recreation Area (GGNRA), Marin, San Francisco, and San Mateo Counties, California between 1990 and 1997. We established 456 permanent study plots in 6 major park habitats, including grassland, coastal scrub, riparian woodland, coastal wetland, broad-leaved evergreen forest, and needle-leaved evergreen forest. We tested multiple inventory methods, including live traps, track plate stations, and artificial cover boards, across all years and habitats. In most years, sampling occurred in 3?4 primary sampling sessions between July and September. In 1994, additional sampling occurred in February and May in conjunction with an assessment of Hantavirus exposure in deer mice (Peromyscus maniculatus). Overall, we detected 32 mammal, 14 reptile, and 6 amphibian species during 25,222 trap-nights of effort. The deer mouse?the most abundant species detected--accounted for 67% of total captures. We detected the Federal Endangered salt marsh harvest mouse (Reithrodontomys raviventris) at one coastal wetland plot in 1992. This project represents the first phase in the development of a comprehensive terrestrial vertebrate inventory and monitoring program for GGNRA. This report summarizes data on relative abundance, frequency of occurrence, distribution across habitat types, and trap success for terrestrial vertebrates detected during this 7-year effort. It includes comprehensive descriptions of the inventory methods and sampling strategies employed during this survey and is intended to help guide the park in the implementation of future longterm ecological monitoring programs.

Phase-shifting the light-dark cycle influences food-anticipatory activity in golden shiners.  

PubMed

This study provides evidence that a circadian light-entrainable oscillator is at least partially involved in the timing of food-anticipatory activity (FAA) in a fish, the golden shiner, Notemigonus crysoleucas. Shoals of four golden shiners were fed for 11-20 days at a fixed daily time (either early night, midnight, late night, early day, midday, or late day). Most (78%) shoals developed peaks of FAA during that period of time. Food was then withheld for 7 days, and the light-dark (LD) cycle was either advanced or delayed by 6 h on the first of those days. The activity waveform of most (53-58%) shoals shifted along with the LD cycle, as indicated by significant correlation coefficients between pre- and postshift waveforms plotted relative to LD. Nonsignificant correlations were linked to low activity levels rather than to persistence of the activity peak at the old clock time. Activity shifts were gradual, taking 2-4 days, which indicates that the underlying mechanism is circadian rather than hourglass. PMID:10978478

Effects of fire on golden eagle territory occupancy and reproductive success  

USGS Publications Warehouse

We examined effects of fire on golden eagle (Aquila chrysaetos) territory occupancy and reproductive success in southwestern Idaho because wildfires since 1980 have resulted in large-scale losses of shrub habitat in the Snake River Plain. Success (percentage of pairs that raised young) at burned territories declined after major fires (P = 0.004). Pairs in burned areas that could expand into adjacent vacant territories were as successful as pairs in unburned territories and more successful than pairs in burned territories that could not expand. Success at extensively burned territories was lowest 4-6 years after burning but increased 4-5 years later. The incidence and extent of fires did not help predict territories that would have low occupancy and success rates in postburn years. The presence of a vacant neighboring territory and the amount of agriculture and proportion of shrubs within 3 km of the nesting centroid best predicted probability of territory occupancy. Nesting success during preburn years best predicted the probability of a territory being successful in postburn years. Burned territories with high success rates during preburn years continued to have high success rates during postburn years, and those with low success in preburn years continued to be less successful after burning. In areas where much shrub habitat has been lost to fire, management for golden eagles should include active fire suppression and rehabilitation of burned areas.

Semi-automated XML markup of biosystematic legacy literature with the GoldenGATE editor.  

PubMed

Today, digitization of legacy literature is a big issue. This also applies to the domain of biosystematics, where this process has just started. Digitized biosystematics literature requires a very precise and fine grained markup in order to be useful for detailed search, data linkage and mining. However, manual markup on sentence level and below is cumbersome and time consuming. In this paper, we present and evaluate the GoldenGATE editor, which is designed for the special needs of marking up OCR output with XML. It is built in order to support the user in this process as far as possible: Its functionality ranges from easy, intuitive tagging through markup conversion to dynamic binding of configurable plug-ins provided by third parties. Our evaluation shows that marking up an OCR document using GoldenGATE is three to four times faster than with an off-the-shelf XML editor like XML-Spy. Using domain-specific NLP-based plug-ins, these numbers are even higher. PMID:17992751

Tropical cloud forest climate variability and the demise of the Monteverde golden toad  

PubMed Central

Widespread amphibian extinctions in the mountains of the American tropics have been blamed on the interaction of anthropogenic climate change and a lethal pathogen. However, limited meteorological records make it difficult to conclude whether current climate conditions at these sites are actually exceptional in the context of natural variability. We use stable oxygen isotope measurements from trees without annual rings to reconstruct a century of hydroclimatology in the Monteverde Cloud Forest of Costa Rica. High-resolution measurements reveal coherent isotope cycles that provide annual chronological control and paleoclimate information. Climate variability is dominated by interannual variance in dry season moisture associated with El Niño Southern Oscillation events. There is no evidence of a trend associated with global warming. Rather, the extinction of the Monteverde golden toad (Bufo periglenes) appears to have coincided with an exceptionally dry interval caused by the 1986–1987 El Niño event. PMID:20194772

Toxicity of dispersant application: Biomarkers responses in gills of juvenile golden grey mullet (Liza aurata).  

PubMed

Dispersant use in nearshore areas is likely to increase the exposure of aquatic organisms to petroleum. To measure the toxicity of this controversial response technique, golden grey mullets (Liza aurata) were exposed to mechanically dispersed oil, chemically dispersed oil, dispersant alone in seawater, water-soluble fraction of oil and to seawater as a control treatment. Several biomarkers were assessed in the gills (enzymatic antioxidant activities, glutathione content, lipid peroxidation) and in the gallbladder (polycylic aromatic hydrocarbons metabolites). The significant differences between chemically dispersed oil and water soluble fraction of oil highlight the environmental risk to disperse an oil slick when containment and recovery can be conducted. The lack of significance between chemically and mechanically dispersed oil suggests that dispersant application is no more toxic than the natural dispersion of the oil slick. The results of this study are of interest in order to establish dispersant use policies in nearshore areas. PMID:21592637

Making Friends: Social Attraction in Larval Green and Golden Bell Frogs, Litoria aurea  

PubMed Central

Socio-ecological models combine environmental and social factors to explain the formation of animal groups. In anurans, tadpole aggregations have been reported in numerous species, but the factors driving this behaviour remain unclear. We conducted controlled choice experiments in the lab to determine whether green and golden bell frog (Litoria aurea) tadpoles are directly attracted to conspecifics (social factors) in the absence of environmental cues. Using repeated measures, we found that individual tadpoles strongly preferred associating with conspecifics compared to being alone. Furthermore, this preference was body size dependent, and associating tadpoles were significantly smaller than non-associating tadpoles. We suggest that small tadpoles are more vulnerable to predation and therefore more likely to form aggregations as an anti-predator behaviour. We demonstrate that tadpoles present an ideal model system for investigating how social and ecological factors influence group formation in vertebrates. PMID:23424662

Avian pox infection with secondary Candida albicans encephalitis in a juvenile golden eagle (Aquila chrysaetos).  

PubMed

Abstract: A juvenile golden eagle (Aquila chrysaetos) was presented with proliferative epithelial lesions, consistent with avian poxvirus infection, around the eyes, on commissures of the beak, and on both feet. Despite treatment, the eagle declined clinically, and, 15 days after presentation, the eagle began seizuring and was euthanatized because of a poor prognosis. On postmortem examination, avian poxvirus infection was confirmed in the nodular skin lesions, and Candida albicans was cultured from the skin, lungs, and brain. Breaks in the skin barrier from poxvirus infection likely led to secondary infection with C albicans. Systemic vascular dissemination of C albicans to the brain resulted in thrombosis, hemorrhage, local hypoxia, and the clinically observed seizures. The combination of the breach in the primary immune system, immunosuppression, and a prolonged course of antibiotics were contributory factors to the opportunistic fungal infection in this eagle. Candida albicans should be considered as a differential diagnosis for encephalitis in an immunocompromised avian patient. PMID:20496607

Behavior genetics of canine aggression: behavioral phenotyping of golden retrievers by means of an aggression test.  

PubMed

Molecular genetic analysis of complex traits such as aggression strongly depends on careful phenotyping of individuals. When studying canine aggression, the information provided by the owners of the dogs is often not detailed and reliable enough for this purpose. Therefore we subjected 83 golden retrievers, both aggressive and nonaggressive individuals, to a behavioral test. These tests were analyzed with help of an ethogram, resulting in a behavioral profile for each of the dogs. In this article three methods are described of converting these profiles into a measure of behavioral phenotype. The usefulness of the methods is evaluated by comparing the test results with information provided by owners. Moreover, the hypothesis underlying all these methods, that a lowered threshold for aggressive behavior in general is present in the dogs, is also evaluated. Future research will need to reveal whether the methods meet the high standards that are necessary for studying complex traits. PMID:14574125

Sleeping site selection by golden-backed uacaris, Cacajao melanocephalus ouakary (Pitheciidae), in Amazonian flooded forests.  

PubMed

In Amazonian seasonally flooded forest (igapó), golden-backed uacaris, Cacajao melanocephalus ouakary, show high selectivity for sleeping trees. Of 89 tree species in igapó, only 16 were used for sleeping (18%). Hydrochorea marginata (Fabaceae) and Ormosia paraensis (Fabaceae) were used most frequently (41% of records) despite being uncommon (Ivlev electivity ratios were 0.76, and 0.84, respectively), though the third most commonly used species (11%), Amanoa oblongifolia (Euphorbiaceae), was selected at near parity. All three species have broad, open canopies with large horizontal limbs and uncluttered interiors. Compared with random trees, sleeping trees had above average diameter at breast height (DBH) and height, lacked lianas and wasp nests, and were more frequently within 5 m of open water. Uacaris generally slept one adult per tree or widely separated in the same canopy and on the outer third of the branch. These behaviours are interpreted as maximising detection of both aerial and arboreal predators. PMID:22371101

Splendide Californie: French Artists' Impressions of the Golden State, 1786-1900  

NSDL National Science Digital Library

The California Historical Society's Website presents accessible, interesting, and well-designed scholarly and educational materials relating to California history. Running March 1 -- June 10, 2001, the site has posted an exhibition of painted images of California -- Splendide Californie French Artists' Impressions of the Golden State, 1786-1900 -- that presents texts and images of French Impressionists painting and drawing California's landscape and culture. Of course, these are lesser-known artists in comparison to their Parisian compatriots, and their artwork is not always as "impressionistic" as the school's exemplars. Nonetheless, the exhibit provides a fascinating look at one of the cultural synergies that took place in the days of California's most frenetic development.

Hormones and the neuromuscular control of courtship in the golden-collared manakin (Manacus vitellinus)  

PubMed Central

Many animals engage in spectacular courtship displays, likely recruiting specialized neural, hormonal and muscular systems to facilitate these performances. Male golden-collared manakins (Manacus vitellinus) of Panamanian rainforests perform physically elaborate courtship displays that include novel forms of visual and acoustic signaling. We study the behavioral neuroendocrinology of this male’s courtship, combining field behavioral observations with anatomical, biochemical and molecular laboratory-based studies. Seasonally, male courtship is activated by testosterone with little correspondence between testosterone levels and display intensity. Females prefer males whose displays are exceptionally frequent, fast and accurate. The activation of androgen receptors (AR) is crucial for optimal display performance, with AR expressed at elevated levels in several neuromuscular tissues. Apparently, courtship enlists an elaborate androgen-dependent network that includes spinal motoneurons, skeletal muscles and somatosensory systems. This work highlights the value of studying non-traditional species to illuminate physiological adaptations and, hopefully, stimulates future research on other species with complex behaviors.

A Pentagonal Crystal, the Golden Section, alcove packing and aperiodic tilings  

E-print Network

A Lie theoretic interpretation is given to a pattern with five-fold symmetry occurring in aperiodic Penrose tiling based on isosceles triangles with length ratios equal to the Golden Section. Specifically a $B(\\infty)$ crystal based on that of Kashiwara is constructed exhibiting this five-fold symmetry. It is shown that it can be represented as a Kashiwara $B(\\infty)$ crystal in type $A_4$. Similar crystals with $(2n+1)$-fold symmetry are represented as Kashiwara crystals in type $A_{2n}$. The weight diagrams of the latter inspire higher aperiodic tiling. In another approach alcove packing is seen to give aperiodic tiling in type $A_4$. Finally $2m$-fold symmetry is related to type $B_m$.

Curcumin, a component of golden spice: from bedside to bench and back.  

PubMed

Although the history of the golden spice turmeric (Curcuma longa) goes back thousands of years, it is only within the past century that we learned about the chemistry of its active component, curcumin. More than 6000 articles published within the past two decades have discussed the molecular basis for the antioxidant, anti-inflammatory, antibacterial, antiviral, antifungal, and anticancer activities assigned to this nutraceutical. Over sixty five clinical trials conducted on this molecules, have shed light on the role of curcumin in various chronic conditions, including autoimmune, cardiovascular, neurological, and psychological diseases, as well as diabetes and cancer. The current review provides an overview of the history, chemistry, analogs, and mechanism of action of curcumin. PMID:24793420

Patterns of social preference across different social contexts in golden lion tamarins (Leontopithecus rosalia).  

PubMed

We investigated the role of mutual and circumstantial factors in maintaining exclusive social relationships in a New World primate. Four breeding pairs of golden lion tamarins (Leontopithecus rosalia rosalia) were allowed to interact with their mate or an unfamiliar, opposite-sex adult in each of 4 different social contexts: in view of the mate, out of the mate's view, with only the mate present, and with only the unfamiliar animal present. Males and females were in proximity to, approached, and sniffed their mates significantly more often than they did unfamiliar tamarins. These behaviors suggest a preference for the familiar mate. However, when mates were absent, tamarins demonstrated significantly higher levels of approach and sniffs toward unfamiliar animals. These patterns of behavior indicate that circumstantial factors, such as social context, may regulate social interactions between paired tamarins and unfamiliar, opposite-sex conspecifics.

Golden Gate Bridge response: a study with low-amplitude data from three earthquakes  

USGS Publications Warehouse

The dynamic response of the Golden Gate Bridge, located north of San Francisco, CA, has been studied previously using ambient vibration data and finite element models. Since permanent seismic instrumentation was installed in 1993, only small earthquakes that originated at distances varying between ~11 to 122 km have been recorded. Nonetheless, these records prompted this study of the response of the bridge to low amplitude shaking caused by three earthquakes. Compared to previous ambient vibration studies, the earthquake response data reveal a slightly higher fundamental frequency (shorter-period) for vertical vibration of the bridge deck center span (~7.7–8.3 s versus 8.2–10.6 s), and a much higher fundamental frequency (shorter period) for the transverse direction of the deck (~11.24–16.3 s versus ~18.2 s). In this study, it is also shown that these two periods are dominant apparent periods representing interaction between tower, cable, and deck.

Increased flight altitudes among migrating golden eagles suggest turbine avoidance at a Rocky Mountain wind installation.  

PubMed

Potential wind-energy development in the eastern Rocky Mountain foothills of British Columbia, Canada, raises concerns due to its overlap with a golden eagle (Aquila chrysaetos) migration corridor. The Dokie 1 Wind Energy Project is the first development in this area and stands as a model for other projects in the area because of regional consistency in topographic orientation and weather patterns. We visually tracked golden eagles over three fall migration seasons (2009-2011), one pre- and two post-construction, to document eagle flight behaviour in relation to a ridge-top wind energy development. We estimated three-dimensional positions of eagles in space as they migrated through our study site. Flight tracks were then incorporated into GIS to ascertain flight altitudes for eagles that flew over the ridge-top area (or turbine string). Individual flight paths were designated to a category of collision-risk based on flight altitude (e.g. flights within rotor-swept height; ?150 m above ground) and wind speed (winds sufficient for the spinning of turbines; >6.8 km/h at ground level). Eagles were less likely to fly over the ridge-top area within rotor-swept height (risk zone) as wind speed increased, but were more likely to make such crosses under headwinds and tailwinds compared to western crosswinds. Most importantly, we observed a smaller proportion of flights within the risk zone at wind speeds sufficient for the spinning of turbines (higher-risk flights) during post-construction compared to pre-construction, suggesting that eagles showed detection and avoidance of turbines during migration.

Sensory effects of hexanal vapor on fresh-cut slices of golden delicious apples.  

PubMed

Hexanal is a natural antimicrobial molecule that characterizes apples aroma. In this paper, the sensory effects of hexanal, as a component of packaging atmosphere, on fresh sliced Golden Delicious apples after storage at 4 °C for 8 d were evaluated. In particular, a colorimetric analysis of slices treated with different concentrations of hexanal vapor (coming from 3.040 to 0.076 mmol of liquid aldehyde per liter of air) fixed at 0.076 mmol/L the amount of hexanal in evaluating sensory effects in the subsequent analysis. Color and texture evaluation of slices by Two-out-of-Five method did not highlight any significant difference between treatment and control. The results from olfactory evaluation showed instead that treated samples had an intense odor compared with those untreated (P < 0.001). A significant difference between treatment and control was also highlighted during the flavor evaluation (P < 0.01); however, from the panelists' observations it emerged that such an effect would work negatively. The positive effect of the tested dose of hexanal on the odor of Golden Delicious slices and its flavor acceptability were verified by using regular apple consumers. A significant preference (P < 0.001) for the odor of treated apple slices came out, so the small dose of hexanal intensifies the odor of apples pleasantly. The different flavor of treated samples was not identified by the consumers, who altogether expressed positive judgments about it. This suggests the nicety of this difference that in the absence of an untreated reference sample is very difficult to detect. PMID:22900672

Hormonal induction of supermale golden rosy barb and isolation of Y-chromosome specific markers.  

PubMed

Viable supermales of the golden rosy barb Puntius conchonius are generated through hormonal sex reversal and progeny testing. Discrete immersion (3 h/day on the second, fourth, and sixth day after hatching) of the fry in Estradiol-17beta (E2) at doses of 400-600 microg/L ensures greater than 40% survival and production of more than 98% F1 females; of these 50% are heterogametic females, that when crossed with normal males, sire 25% YY supermales. Supermales sire female progenies at the frequencies between 0 and 8%. Reproductive performance of hormonally sex-reversed females and androgenetic females is inferior to the normal ones. Conversely, the performance of androgenetic males is superior but suffers from low fertilizability. The relative performance of supermale produced by breeding sex-reversed parents is superior to those produced by androgenesis. Using the SRY-specific primers, the PCR analysis of the genomic DNA of the male golden rosy barb produces three products of 588, 333, and 200 bp length. However only the 200 bp product is amplified in the female genome. Hence it is possible to use the first two products as molecular markers to rapidly identify fish possessing a Y chromosome. The presence of 333 and 588 bp fragments in normal (X1Y2), hormonally induced (Y1Y2) and androgenetic (Y2Y2) males and the absence of relation between the 200 bp fragment and the X-chromosome indicates that the male specific markers are specific to Y-chromosome. For the first time, a Y-chromosome specific molecular marker for a cyprinid has been identified, isolated, and characterized. PMID:13129504

A population study of golden eagles in the Altamont Pass Wind Resource area. Second-year progress report  

SciTech Connect

Since January 1994, the Predatory Bird Research Group, University of California, Santa Cruz, has been conducting a field investigation of the ecology of golden eagles (Aquila chrysaetos) in the vicinity of the Altamont Pass Wind Resource Area (WRA). The 190 km{sup 2} facility lies just east of San Francisco Bay in California and contains about 6,500 wind turbines. Grassland and oak savanna habitats surrounding the WRA support a substantial resident population of golden eagles. Each year, the U.S. Fish and Wildlife Service receivers reports from the wind industry of about 30 golden eagle casualties occurring at the WRA, and it is probable that many more carcasses go unnoticed. Over 90 percent of the casualties are attributed to collisions with wind turbines. The main purpose of this study is to estimate the effect of turbine-related mortality on the golden eagle population of the area. Assessing the impact of the WRA kills on the population requires quantification of both survival and reproduction. To estimate survival rates of both territorial and non-territorial golden eagles, we tagged 179 individuals with radio-telemetry transmitters expected to function for about four years and equipped with mortality sensors. Population segments represented in the tagged sample include 79 juveniles, 45 subadults, 17n floaters (non-territorial adults), and 38 breeders. Effective sample sizes in the older segments increase as younger eagles mature or become territorial. Since the beginning of the study, we have conducted weekly roll-call surveys by airplane to locate the tagged eagles in relation to the WRA and to monitor their survival. The surveyed area extends from the Oakland Hills southeast through the Diablo Mountain Range to San Luis Reservoir about 75 km southeast of the WRA. The surveys show that breeding eagles rarely enter the WRA while the non-territorial eagles tend to move about freely throughout the study area and often visit the WRA.

Coastal Processes and Geomorphology along Crissy Beach and Inside San Francisco's Golden Gate  

NASA Astrophysics Data System (ADS)

The Golden Gate inlet to San Francisco Bay is a highly dynamic zone for sediment transport and geomorphic patterns. The behavior of the coastline has historically not been considered during land use planning, leading to a heavily manipulated shoreline in areas such as Ocean Beach, Crissy Field and other portions of the northern shore of San Francisco. Understanding of the regional and local coastal processes is even more important for future land-use planning and habitat restoration as sea level rises. The goal of this study is to present a summary of the coastal dynamics that govern the geomorphology of Crissy Field Beach and Marsh area, and estimate the future shore response to sea level rise. The Crissy Field marsh restoration in the late 1990s marked a new stage of studying coastal processes in this area of the Golden Gate Littoral Cell. For the past decade, the USGS and ESA PWA have conducted hydrodynamic, sediment transport, and geomorphic investigations extending from Ocean Beach to Crissy Marsh. USGS work has been driven by understanding the long-term function of the marsh while ESA PWA has focused on applying science to address coastal engineering and shoreline protection issues. We present a synthesis of this body of work as an example of successful public-private collaboration on coastal sciences. Several datasets were combined to characterize the region's dynamism. The local wave climate includes short period waves generated from local winds blowing over San Francisco Bay and longer period waves (swell) that arrive at Crissy Field from distant sources through the Golden Gate entrance. Tidal current data and model simulations indicate the presence of a residual circulation cell with ebb -dominance (eastward flow) offshore of Crissy Beach and a weaker westward current in the very nearshore region. Cross-shore transects of bathymetry and topography from 1947, 1978, 1997, 2007 and 2008 suggest patterns of erosion and deposition patterns occur on decadal, annual and seasonal timescales. Variability of the shoreline was further analyzed using the Digital Shoreline Analysis System (DSAS) in GIS, based on decadal aerial photographs beginning in the 1920s and long-term dredging records from the San Francisco Marina located immediately east of Crissy Beach. Based on the data and numerical modeling results, an overall sediment budget was estimated to determine the trends of potential geomorphic change. The geomorphic response to sea-level rise is vital to infrastructure design at Crissy Beach. Based on compilation and analysis of USGS and ESA PWA data and model results describing historic and present conditions, the accretion patterns on the west part of the beach are not expected to continue linearly. Incorporating anticipated sea level-rise rates established for California (0.35 m by 2050, 1.40 m by 2100), ESA PWA's calculated water levels are projected to exceed estimated shoreline elevations calculated from accretion rates. Transgression of the beach upward and landward is expected, as long as space is available for managed retreat.

Flexible Retrospective Selection of Temporal Resolution in Real-time Speech MRI Using a Golden-Ratio Spiral View Order  

PubMed Central

In speech production research using real-time MRI, the analysis of articulatory dynamics is performed retrospectively. A flexible selection of temporal resolution is highly desirable because of natural variations in speech rate and variations in the speed of different articulators. The purpose of the study is to demonstrate a first application of golden-ratio spiral temporal view order to real-time speech MRI and investigate its performance by comparison with conventional bit-reversed temporal view order. Golden-ratio view order proved to be more effective at capturing the dynamics of rapid tongue tip motion. A method for automated blockwise selection of temporal resolution is presented that enables the synthesis of a single video from multiple temporal resolution videos and potentially facilitates subsequent vocal tract shape analysis.
