Demographic dynamics of the Suyá, a Jê people of the Xingu Indigenous Park, Central Brazil, 1970-2004.  

PubMed

This paper analyses the demographic dynamics of the Suyá, a Jê people, inhabitants of the Xingu Indigenous Park, Mato Grosso State, Brazil, during the years 1970-2004. Data was gathered from medical records of the São Paulo Federal University Health Program at the Xingu Indigenous Park. The demographic characteristics addressed include composition by age and sex, crude birth rates, general mortality rates, mortality rates by age and sex, proportional mortality by sex, age, and basic causes of death. The results show a population recovery process, with growth rates of 3% per year between 1970 and 2004. In addition to moderate birth rates and declining mortality rates, migration has also played an important role in the demographic dynamics. Mortality indicators show a decline in general and infant mortality rates, higher death rates among women, higher proportions of deaths among individuals < 1 and 50+ years of age, and major causes of death to be infectious diseases and cancer.

Assessing Physical Activity in Public Parks in Brazil Using Systematic Observation  

PubMed Central

Objectives. We assessed park use in Recife, Brazil, and differences in physical activity and occupation rates in public parks with and without the Academia da Cidade Program (ACP), which provides cost-free, supervised physical activity classes. Methods. We used the System for Observing Play and Recreation in Communities (SOPARC) in 128 targeted areas in 10 park sites (5 ACP sites, 5 non-ACP sites) to obtain data on the number of users and their physical activity levels and estimated age. Each area was assessed 4 times a day for 11 days over a 4-week period. Results. A total of 32 974 people were observed during 5589 observation visits to target areas. People using ACP parks were more likely to be seen engaging in moderate-to-vigorous (64% vs 49%) and vigorous (25% vs 10%) physical activity. Relatively more participants in ACP sites than in non-ACP sites were females (45% vs 42% of park users) and older adults (14.7% vs 5.7% of park users). Conclusions. On the basis of systematic observation, ACP appears to be a useful strategy in promoting park use and physical activity among the population in Recife.

Evaluation of the noise pollution in urban parks of Curitiba, Brazil  

NASA Astrophysics Data System (ADS)

This work shows a study about the noise pollution found in six urban parks of Curitiba, Paran, Brazil. The equivalent noise levels (Leq) have been measured in points spread throughout the park, and interviews have been conducted with some park visitors. It has been found out that 52.48% out of the measurement sites did not satisfy the Municipal Law no. 10,625, which states the noise emission level of 55 dB(A) as the limit value for green areas. The results of the questionnaires applied to the local visitors have showed that 39% out of the interviewed people used to visit the park every day and that 75% out of them seek for the realization of a physical activity. During the realization of their activities in the parks, 22% out of the interviewed people pointed to the noise pollution as the source of annoyance and 28% out of them pointed the local security. In this sense, it has been verified that half of the analyzed parks were inserted in acoustically polluted areas, which incurs a real state depreciation in their vicinities.

POLYCYCLIC AROMATIC HYDROCARBONS ASSESSMENT IN SEDIMENT OF NATIONAL PARKS IN SOUTHEAST BRAZIL  

PubMed Central

The aim of this work was to assess the levels of polycyclic aromatic hydrocarbons (PAHs) in the environment and their sources found in protected regions of southeastern Brazil. Samples of sediments were collected at four National Parks: Itatiaia National Park (PNIT), Serra da Bocaina National Park (PNSB), Serra dos Orgãos National Park (PNSO) and Jurubatiba National Park (PNJUB). The National Parks studied comprise rainforests, altitudinal fields and ‘restinga’ environments located in the Minas Gerais, Rio de Janeiro and São Paulo states. The sampling was conducted between 2002 and 2004 from June to September. In general, the environmental levels of PAHs found were similar to those in other remote areas around the globe. PNIT exhibited the highest median values of total PAHs in sediment (97 ng·g?1), followed by PNJUB (89 ng·g?1), PNSO (57 ng·g?1) and PNSB (27 ng·g?1). The highest levels of total PAHs (576 and 24430 ng·g?1) could be associated to a point source contamination where are characterizated for human activities. At PNSB and PNIT the PAH profiles were richer in 2 and 3 ring compounds, whereas at PNSO and PNJUB, the profiles exhibited 3 and 4 ring compounds. The phenanthrene predominance in most samples could indicate the influence of biogenic synthesis. The samples with a petrogenic pattern found in this study might be associated with the vicinity of major urban areas, highway traffic and/or industrial activities close to PNSO and PNIT. At PNIT and PNJUB, forest fires and slash and burn agricultural practices may drive the results towards a pyrolytic pattern.

Population genetic structure of Sisyrinchium micranthum Cav. (Iridaceae) in Itapu? State Park, Southern Brazil  

PubMed Central

Sisyrinchium micranthum Cav. is a member of the family Iridaceae, which is distributed over the American continent. In Brazil, this species is found, not only in disturbed areas and coastal regions, but is also very common in urban centers, such as public parks, during the spring. Chromosome counts for North American specimens are 2n = 32 and 2n = 48, whereas in southern Brazil, there is a polyploidy series with three chromosome numbers, 2n = 16, 2n = 32, and 2n = 48. Population analyses using DNA molecular markers are inexistent for this species, in spite of its wide distribution and morphological variation. To study the genetic population structure of S. micranthum, five natural populations were accessed in a conservation park within the Atlantic Rain Forest Biome in southern Brazil. Here, the chromosome numbers 2n = 16 and 2n = 48 had already been described. Molecular analysis showed that the populations are highly structured with low gene flow among them. The population with 2n = 48 was genetically less variable than and distinct from the other populations. Population genetics in relation to cytogenetic data provided new insights regarding the genetic diversification and mating system of S. micranthum.

Diversity of phlebotomine sand flies (Diptera: Psychodidae) in Ibitipoca State Park, Minas Gerais, Brazil.  

PubMed

Leishmaniasis is a complex of zoonotic diseases that are endemic to many Brazilian states. They are transmitted to the vertebrates by the bite of the hematophagous female sand fly (Diptera: Psychodidae) vectors. Despite the increasing occurrence of visceral and cutaneous leishmaniasis cases in large urban centers, their transmission continues to occur primarily in a wild environment and may be associated with professional activities, ecotourism activities, or both. This study investigates the ecological parameters of the sand flies present in Ibitipoca State Park, Minas Gerais, Brazil. During 2009, systematic collections of sand flies were made monthly using HP light traps installed at five sites, including three natural settings (a cave, riparian vegetation, and a rain forest), the tourist and researchers' accommodations, and a surrounding domestic livestock area. In total, 161 sand flies (seven species) were collected, the most abundant, particularly in the surrounding domestic livestock area, being Lutzomyia (Psychodopygus) lloydi (Antunes, 1937). Furthermore, a previously unidentified Lutzomyia (Sciopemyia) sp. was prevalent in the cave environment. There are no existing records of the occurrence of leishmaniasis in Ibitipoca State Park; however, the some species of the subgenus Psychodopygus are known vectors of Leishmania spp in Brazil. Hence, the presence of a species of this genus in areas surrounding the park may represent a risk to ecotourism and the local inhabitants. Our study shows the importance of regular monitoring of the various areas used by humans to determine the distribution and spread of sand fly vectors for preventive management to forestall potential risk to health and consequent effect on ecotourists.

Intra-plate seismicity and flexural stresses in central Brazil  

NASA Astrophysics Data System (ADS)

Explaining intra-plate seismicity is a challenging task. Different models have been proposed combining weak zones and stress concentration mechanisms. Here we propose that flexural deformation is a major factor to explain seismicity in Central Brazil. A SW-NE-oriented seismic zone between the Amazon and the São Francisco cratons coincides with high gravity anomalies, possibly due to a SW-NE belt of thin crust. The load from the high-density, shallow mantle rocks causes upper crustal compressional stresses up to 100 MPa in the 200 km wide seismic zone. Away from the central zone of horizontal compression, extensional stresses in the peripheral bulge balance the regional compression explaining the aseismic areas. Three other seismic clusters in Brazil also correlate with high gravity anomalies, suggesting that flexural deformation contributes significantly to explain mid-plate seismicity in Brazil.

Climatic factors influencing triatomine occurrence in Central-West Brazil.  

PubMed

We estimated the geographic distributions of triatomine species in Central-West Region of Brazil (CW) and analysed the climatic factors influencing their occurrence. A total of 3,396 records of 27 triatomine species were analysed. Using the maximum entropy method, ecological niche models were produced for eight species occurring in at least 20 municipalities based on 13 climatic variables and elevation. Triatoma sordida and Rhodnius neglectus were the species with the broadest geographic distributions in CW Brazil. The Cerrado areas in the state of Goiás were found to be more suitable for the occurrence of synanthropic triatomines than the Amazon forest areas in the northern part of the state of Mato Grosso. The variable that best explains the evaluated models is temperature seasonality. The results indicate that almost the entire region presents climatic conditions that are appropriate for at least one triatomine species. Therefore, it is recommended that entomological surveillance be reinforced in CW Brazil. PMID:23778666

[Seasonal dynamics of Amblyomma ticks (Acari:Ixodidae) in an urban Park of Londrina City, Parana, Brazil].  

PubMed

Ticks are important to public health due to diseases they transmit to animals and humans and, economic losses they cause to livestock production. Among other agents, such as Babesia, Ehrlichia, Anaplasma, the Rickettsia are the most important pathogens transmitted by ticks in Brazil. Worldwide there are about 870 tick species described and, of these, 55 species were already reported in Brazil, being the genus Amblyomma the most numerous with 33 species. The A. cajennense is the principal tick involved in the transmission of the Brazilian Spotted Fever. New cases of the disease, in some regions of Brazil, have been associated with the increment of the capybara population, wild animal considered primary host for A. cajennense and A. dubitatum. The objectives of this work were to identify and study the population dynamic of free-living ticks species presents in the Arthur Thomas Municipal Park, where lives a group of capybaras, among other wild animals and birds. From August 2006 to July 2007, free-living nymph and adult tick stages were collected using carbon dioxide traps, and for larvae capture was used the technique of the dragging with white flannel. All the ticks captured were transported to the laboratory, fixed in ethanol, counted and identified by morphological criteria. The three stages of the genus Amblyomma spp were present all over the 12 months of the studied period. Larvae and nymphs were present in the park all over the year with population peaks in both semesters of the studied period. Adult of A. cajennense were more abundant on the ground of the park during the spring-summer months and, A. dubitatum presented populational peaks in September/ October, 2006 and July, 2007. Considering these data it can be concluded that visitors and people that work in the park are exposed to the ticks all over the year, with larger risk of attacks in the hottest months. PMID:20059815

Archaean gold mineralization in central eastern Brazil: a review  

NASA Astrophysics Data System (ADS)

A brief outline of the nature and distribution of the major Archaean terranes of central eastern Brazil is given in the first section of this paper. Integration of presently available data indicates that the entire Archaean gold mineralization of some economic importance is restricted to greenstone-type lithostratigraphic sequences such as those occurring in the Sao Francisco craton and the Jequie and Goias mobile belts of central eastern Brazil. This mineralization associated with greenstone belts consists of two different genetical types: (1) a stratiform syngenetic type intimately associated with its host rocks and (2) a structurally controlled epigenetic type related to hydrothermal solutions. The study of the former type includes a detailed description of the major gold mines of the Iron Quadrangle where the gold mineralization is closely associated with various types of banded iron formations (BIF), providing clear geological and geochemical evidence for their syngenetic exhalative volcano-sedimentary origin. The epigenetic type is best exemplified by the orebodies of the “Faixa Weber” within the mafic metavolcanic unit of the Rio Itapicuru belt and other small gold occurrences such as those present in the Crixas belt.

Twentieth century atmospheric metal fluxes into Central Park Lake, New York City  

SciTech Connect

It is generally assumed that declining atmospheric lead concentrations in urban centers during the 1970s and 1980s were due almost entirely to the progressive introduction of unleaded gasoline. However, most environmental data are from monitoring programs that began only two to three decades ago, which limits their usefulness. Here, trace metal and radionuclide data from sediment cores in Central Park Lake provide a record of atmospheric pollutant deposition in New York City through the 20th century, which suggests that leaded gasoline combustion was not the dominant source of atmospheric lead for NYC. Lead deposition rates, normalized to known Pb-210 atmospheric influxes, were extremely high, reaching maximum values from the late 1930s to early 1960s, decades before maximum emissions from combustion of leaded gasoline. Temporal trends of lead, zinc, and tin deposition derived from the lake sediments closely resemble the history of solid waste incineration in New York City. Furthermore, widespread use of solid waste incinerators in the United States and Europe over the last century suggests that solid waste incineration may have provided the dominant source of atmospheric lead and several other metals to many urban centers.

Demography and health of the Xavante Indians of Central Brazil.  

PubMed

This study investigates the demographic and health behavior of the Xavante Indians of Mato Grosso State, Central Brazil. Data covering the period 1999 to 2004 was collected using information from household censuses and vital statistics. In addition to standard demographic analyses, survival analysis was carried out. Results show a young age structure, derived from a combination of high fertility rates (7.7 live births per woman) and declining mortality. Mortality rates, especially infant mortality (97 per thousand), remain very high, surpassing regional and national rates. Natural increase is the main contributing factor to population growth. The annual population growth rate is 4.4%. Results suggest that recent declines in mortality and fertility may be related to transformations in the implementation of basic health care services and internal diversity, the latter of which seems to be associated with local history and sociocultural determinants.

Molecular tracers of saturated and polycyclic aromatic hydrocarbon inputs into Central Park Lake, New York City  

SciTech Connect

Saturated hydrocarbons (SH) and polycyclic aromatic hydrocarbons (PAHs) have been quantified in a sediment core obtained from Central Park Lake, New York City. Radionuclides {sup 210}Pb and {sup 137}Cs were used to assign approximate dates to each individual section in the core. The dating profile based on {sup 210}Pb matches very well with the time constraints provided by {sup 137}Cs. Radionuclide-derived depositional dates are consistent with temporal information from the petroleum-indicator ratio U/R (the ratio of unresolved complex mixture (UCM) to saturated hydrocarbons in the aliphatic fraction) and the history of fuel use in the NYC area. Ratios of 1,7-dimethylphenanthrane (DMP) to 1,7-DMP plus 2,6-DMP (1,7/(1,7 + 2,6)-DMP), retene to retene plus chrysene (Ret/(Ret + Chy)), and fluoranthene to fluoranthene plus pyrene (Fl/(Fl + Py))) provide additional source discrimination throughout the core. Results show that the ratio U/R is sensitive to petroleum inputs and Ret/(Ret + Chy) is responsive to contributions from softwood combustion, whereas both Fl/(Fl + Py) and 1,7/(1,7 + 2,6)-DMP can be used to discriminate among wood, coal, and petroleum combustion sources. Combined use of these ratios suggests that in New York City, wood combustion dominated 100 years ago, with a shift to coal combustion occurring from the 1900s to the 1950s.

Changes in determinants of deforestation and forest degradation in Popa Mountain Park, Central Myanmar.  

PubMed

Implementing effective conservation requires an understanding of factors affecting deforestation and forest degradation. Previous studies have investigated factors affecting deforestation, while few studies have examined the determinants of both of deforestation and forest degradation for more than one period. To address this gap, this study examined factors influencing deforestation and forest degradation during 1989-2000 and 2000-2005 in the Popa Mountain Park, Myanmar. We applied multinomial logistic regression (MNL) using land cover maps derived from Landsat images as the dependent variables as well as spatial and biophysical factors as the independent variables. The MNL models revealed influences of the determinants on deforestation and forest degradation changes over time. For example, during 1989-2000, deforestation from closed forest was positively correlated to the distance from the park boundary and was negatively correlated with distance from villages, roads, the park circular road, slope, western aspect and elevation. On the other hand, during 2000-2005, deforestation of closed forest was positively correlated with distance from villages, roads, the park circular road, slope and western aspect, and negatively correlated with distance from the park boundary and elevation. Similar scenarios were observed for the deforestation of open forest and forest degradation of closed forest. The study also found most of the determinants influenced deforestation and forest degradation differently. The changes in determinants of deforestation and forest degradation over time might be attributable to the general decrease in resource availability and to the effect of conservation measures conducted by the park.

Nutritional status and growth of indigenous Xavante children, Central Brazil  

PubMed Central

Background The aim of this study was to characterize the nutritional status of Xavante Indian children less than 10 years of age in Central Brazil and to evaluate the hypothesis of an association between child nutrition and socioeconomic differentiation in this population. Methods A cross-sectional study was conducted in July 2006 that included all children under the age of 10 from the Xavante village Pimentel Barbosa in Mato Grosso, Brazil. The data collected included weight, height, and sociodemographic information. Sociodemographic data were used to generate two indices ("income" and "wealth") and to determine the proportion of adults in each household. Descriptive analyses were performed for weight-for-age (W/A), height-for-age (H/A), and weight-for-height (W/H) using the NCHS and the WHO growth references. Univariate and multivariate analyses were conducted using H/A and W/A as a response variables. Results Of a total of 246 children under the age of ten residing in the village, 232 (94.3%) were evaluated. Following the NCHS reference, 5.6% of children under the age of ten presented low W/A and 14.7% presented low H/A. Among children under the age of five, deficit percentages for weight and height were 4.5% and 29.9%, respectively, following the WHO curves. Among children < 2 years of age, H/A index variability was found to be directly related to child's age and inversely related to the proportion of adults in the household. Maternal BMI was positively associated with growth for children from 2 to 4 years of age, explaining 11.5% of the z-score variability for the H/A index. For children 5 years of age and older, the wealth index and maternal height were positively associated with H/A. No significant associations were found using W/A as the dependent variable. Conclusion This study demonstrated that undernutrition, in particular linear growth deficit, is a notable health issue for Xavante children. These findings contrast with the nutritional profile observed among Brazilian children nationally, which is characterized by a sharp decline in child undernutrition in recent decades, even in the poorest regions of the country. This discrepancy calls attention to the persistent health disparities that exist between indigenous and non-indigenous people in Brazil.

The distribution and relative abundance of sand fly species were studied in the municipality of Barreirinhas, Maranhão State, Brazil, around the Lençóis Maranhenses National Park, from January to June 2005, August 2004, July 2005, and September/2008. A total of 6,658 specimens were captured. The most frequent species were Lutzomyia whitmani (46.6%), L. longipalpis (29.9%), L. evandroi (17.1%), and L. lenti (4.8%), while L. termitophila, L. flaviscutellata, L. migonei, L. infraspinosa, L. sordellii, L. wellcomei, L. antunesi, and L. trinidadensis represented 1.6%. The presence of Leishmania vector species explains the high detection rate for tegumentary leishmaniasis in 2000 (308.2), 2001 (310.9), 2002 (338.2), and 2005 (313.6) and active foci of human visceral leishmaniasis in the municipality of Barreirinhas.

Future drying of the southern Amazon and central Brazil  

NASA Astrophysics Data System (ADS)

Recent climate modeling suggests that the Amazon rainforest could exhibit considerable dieback under future climate change, a prediction that has raised considerable interest as well as controversy. To determine the likelihood and causes of such changes, we analyzed the output of 15 models from the Intergovernmental Panel on Climate Change Fourth Assessment Report (IPCC/AR4) and a dynamic vegetation model VEGAS driven by these climate output. Our results suggest that the core of the Amazon rainforest should remain largely stable. However, the periphery, notably the southern edge, is in danger of drying out, driven by two main processes. First, a decline in precipitation of 24% in the southern Amazon lengthens the dry season and reduces soil moisture, despite of an increase in precipitation during the wet season, due to the nonlinear response in hydrology and ecosystem dynamics. Two dynamical mechanisms may explain the lower dry season precipitation: (1) a stronger north-south tropical Atlantic sea surface temperature gradient; (2) a general subtropical drying under global warming when the dry season southern Amazon is under the control of the subtropical high pressure. Secondly, evaporation will increase due to the general warming, thus also reducing soil moisture. As a consequence, the median of the models projects a reduction of vegetation by 20%, and enhanced fire carbon flux by 10-15% in the southern Amazon, central Brazil, and parts of the Andean Mountains. Because the southern Amazon is also under intense human influence, the double pressure of deforestation and climate change may subject the region to dramatic changes in the 21st century.

Assessment of the quality of stormwater from an industrial park in central Taiwan.  

PubMed

The purposes of this study were to assess the quality of rainstorm runoffs from an industrial park developed to accommodate general industries in Taiwan and to investigate the possible contributors of pollutants in the runoffs. Rainstorm runoffs from this industrial park were found to contain COD and TSS with average event mean concentrations of two events of 2,202.6 ± 1,356 and 784.7 ± 409 mg/l, respectively. The pollution level of these runoffs was found to be tens of times higher than that which may be contributed by accumulation of pollutants in top soils. Other possible sources of the pollutants were those accumulated in rainwater discharge channels and those which overflow from individual pre-treatment plants within the industrial lots. The assessment results are useful in devising the best management practices for the stormwater discharges. The heavy loadings suggest that installations of additional runoff pollution control practices at different zones are necessary at this and similar industrial parks. PMID:21544496

Seasonal variation of the phytoplankton community structure in the São João River, Iguaçu National Park, Brazil.  

PubMed

The limnological characteristics and the phytoplankton community of the pelagic region of the São João River, tributary of the Iguaçu River, Iguaçu National Park were analyzed from August 2008 to July 2009. 221 taxa were identified and the Bacillariophyceae class was the most representative. Bacillariophyceae and Chrysophyceae were the dominant classes in density and Bacillariophyceae in biovolume. According to the DCA carried out for phytoplankton density and biovolume, significant differences were identified between the periods, and between the sites and study periods, respectively. The highest richness of species reached 40 taxa in September 2008 at station 1. The Shannon-Wiener diversity indexes and evenness, calculated from the density of phytoplankton, were temporally heterogeneous and spatially similar. In general, the significant temporal variations in the composition of the phytoplankton community were due to variations in limnological conditions, mainly temperature, transparency and nutrients. Spatially the structure was more similar due to the proximity among the stations. Moreover, the similarity of the distribution of communities in lotic environments were due to the unidirectional flow. PMID:23644782

Epidemiology of HIV Infection in Central Brazil: Data From Voluntary Counseling and Testing Centers.  

PubMed

Voluntary counseling and testing (VCT) is recommended to facilitate early identification of HIV infection. Data from VCT centers in Goiás and Federal District, Central Brazil, evaluated HIV prevalence and identified risk factors for HIV among individuals ages 13 years and older. Results indicated a 1.5% overall prevalence of HIV. Factors independently associated with HIV infection were: getting tested in a large city, being illiterate, having had a previous HIV test, living with an HIV-infected sexual partner, and being a noninjection illicit drug user. Being referred by friends was strongly associated with HIV infection. For men, being a health care worker, sex worker, man who has sex with men, or injection drug user were significant. In Central Brazil, HIV remains concentrated in males and subpopulations with known risk behaviors. Higher prevalence among individuals referred to VCT by friends highlights the importance of social network-based HIV prevention interventions in Brazil. PMID:23465400

Since the emergence of West Nile virus (WNV) in North America in 1999, there have been several reports of WNV activity in Central and South American countries. To detect WNV in Brazil, we performed a serological survey of horses from different regions of Brazil using recombinant peptides from domain III of WNV. Positive samples were validated with the neutralisation test. Our results showed that of 79 ELISA-positive horses, nine expressed WNV-specific neutralising antibodies. Eight of the infected horses were from the state of Mato Grosso do Sul and one was from the state of Paraíba. Our results provide additional evidence for the emergence of WNV in Brazil and for its circulation in multiple regions of the country. PMID:24037110

Temperate and semi-arid tufas in the Pleistocene to Recent fluvial barrage system in the Mediterranean area: The Ruidera Lakes Natural Park (Central Spain)  

NASA Astrophysics Data System (ADS)

The Ruidera Lakes Natural Park, in Central Spain, contains a well-exposed Pleistocene to Recent freshwater carbonate (tufa) succession dominated by fluvial barrages and lacustrine deposits. The majority of exposed tufas are Holocene to Recent in age. Today, carbonate accumulation is currently manifested as active phytoherm barrage constructions, marginal lacustrine stromatolitic terraces, lacustrine lime muds (all produced mainly by precipitation) and sand-size detrital tufa. The depositional history of the Ruidera Park sites has been interpreted from natural outcrops, rotary drill and percussion auger cores. These reveal a long Quaternary record of microbially dominated barrage framework developments and associated lacustrine carbonates. These alternate with frost weathering deposits and detrital tufa episodes, especially during cooler conditions. U-series dating of several earlier tufa deposits within the park indicates four distinct episodes of tufa development at 190 250 ka B.P., 90 130 ka B.P., 30 40 ka B.P. and 16 ka B.P. Present. The three oldest episodes appear to be related to cyclic tufa-building events associated with warm periods of Oxygen Isotope Stages (OIS): 7, 5 and 3. Growth under present conditions is slow and several barrages have been damaged by human activity and drought events.

Ecotoxicological assessment of sediments from an urban marine protected area (Xixová-Japuí State Park, SP, Brazil).  

PubMed

This study aimed to evaluate the environmental quality of the marine portion of Xixová-Japuí State Park (XJSP), an urban marine protected area, which is influenced by multiple contamination sources, by using ecotoxicological and geochemical analyses. Sediments were predominantly sandy, with low CaCO3 and organic matter contents, and presented contamination by metals (Cd,Cu,Zn). Acute toxicity was detected in three tested samples, and copepod exposed to sediments from four stations exhibited lower fecundities, despite the absence of significant effects. Contamination and toxicity seemed to be associated, suggesting that the environment is degraded and presents risks to the biota. Whole sediment TIE indicated ammonia as a main responsible for toxicity, suggesting sewage is a main contributor to sediment degradation. As external contamination sources seem to be negatively influencing the sediment quality, the park conservation objectives are not being fully reached, demanding actions to mitigate impacts.

In order to investigate the hepatitis C virus (HCV) infection prevalence and risk factors in hemophiliacs in Central Brazil, 90 patients were interviewed and serum samples tested for HCV RNA and anti-HCV antibodies. An overall prevalence of 63.3% (CI 95%: 53.0-72.7) was found. Multivariate analysis of risk factors showed that number of blood transfusions was significantly associated with this infection. Most hemophiliacs received locally produced cryoprecipitate. All infected patients were transfused before the screening of blood units for anti-HCV. However, hemophiliacs who received exclusively screened cryoprecipitate were HCV negative. It confirms the expected decline in transfusion-acquired hepatitis C. PMID:12219127

Crustal structure model of Central Section of Tocantins Province, Central Brazil, with deep seismic refraction and gravity data  

NASA Astrophysics Data System (ADS)

This research is based on the execution of two lines of deep seismic refraction of 300 km of extension (L1- Porangatu and L2-Cavalcante), crossing over central section of Tocantins Province in Central Brazil, from west to east by using, in each line, 120 seismographs with digital recording, and explosions with controlled time and explosive charges between 500 and 1,000 kg in each 50 km; GPS receivers were employed in order to control hour and geographical coordinates from recording points. This kind of experiment under those conditions is pioneer in Brazil. Initially the experiment data, which have been considered of good quality, allowed the elaboration of 1D models, using TTInvers program. Successive models were related to represent layers with similar characteristics in a preliminary model aiming of modelling in 2D, accomplished with MacRay program. The 2D models obtained in this work represent the final result of seismic velocity distribution from crust beneath L1 and L2 lines. Results show a crust under central section of Tocantins Province with thickness varying from 36 to 43 km, and whose parameters are correlated to main geological structures existents in surface. Vp as well as Vp/Vs ratio mean values vary about 6.5 km/s and 1.74, respectively, with the exception of fold-thrust belt, whose values are 6.3 km/s and 1.73. Those values reach 6.8 km/s and 1.74 beneath São Francisco craton. There are indicia of double subduction occurred in eastern portion of Tocantins Province with São Francisco craton subducting to west (in ~760 Ma), as well as in western portion, with São Francisco craton subducting to east (in ~620 Ma). The gravimetric model, obtained in this work based on this work seismic model, adequately adjusts with observed gravimetric data by using theoretical densities slightly modified, within the limits allowed by the function employed to calculating the densities based on modelled Vp values. Adopted mantle densities to modelling took in consideration Paleoproterozoic age, beneath São Francisco craton, less dense (3.31 g/cm3), and with higher Vp (8.26 km/s), as well as Neoproterozoic one, beneath Tocantins Province, denser (3.34 g/cm3), and with lower Vp (8.07 km/s).

Uvá complex, the oldest orthogneisses of the Archean-Paleoproterozoic terrane of central Brazil  

NASA Astrophysics Data System (ADS)

The Archean-Paleoproterozoic terrane of central Brazil is an exotic and allochthonous part of the Tocantins Province, a large Brasiliano/Pan-African orogen of the South American Platform formed during the Brasiliano orogeny. The terrane amalgamated to the province during the late stages of the orogeny as a crustal segment consisting of six Archean orthogneiss complexes and five low-grade metamorphic, in part Paleoproterozoic (Rhyacian) greenstone belts. The Uvá complex is the southernmost orthogneiss association of the Archean-Paleoproterozoic terrane of central Brazil. New U-Pb LA-ICP-MS data from zircon crystals show that the complex formed at least during two magmatic stages. The older consists of polydeformed tonalite and granodiorite batholitic and diorite stock protoliths with igneous age of 3040 Ma to 2930 Ma. The youngest comprises tonalite, monzogranite and granodiorite tabular bodies formed between 2876 and 2846 Ma. As compared to the orthogneisses of the northern portion of the terrane, both the oldest and youngest granitogenesis stages of the Uvá complex are, in average, about 150 Ma older. This suggests that the northern and southern orthogneisses formed during different times as independent crustal segments, but when and why they amalgamated is still under investigation.

Impacts of animal traffic on the Brazilian Amazon parrots (Amazona species) collection of the Quinzinho de Barros Municipal Zoological Park, Brazil, 1986-2007.  

PubMed

Eleven species of Amazon parrots (genus Amazona) are known to occur in Brazil, and nest poaching and illegal traffic pose serious conservation threats to these species. When the illegal owners realize these animals are incompatible with their expectations and lifestyle, or when the police arrests traders and owners, these trafficked animals are often considered unfit for release and sent to local zoos and captive breeders. A retrospective survey of animal and necropsy records from 1986 to 2007 was used to evaluate the impacts of animal traffic on the population composition and mortality patterns of Amazon parrots at the Quinzinho de Barros Municipal Zoological Park, Sorocaba, Brazil. Data were obtained for 374 Amazon parrots of ten Brazilian species, and there was evidence that the studied population could be split into two major groups: a majority belonging to the Amazona aestiva species and a minority belonging to the remaining species. In comparison, the animals of the first group were more frequently admitted from traffic-related origins (98 vs. 75%), had a shorter lifespan (median 301 days vs. 848 days) and a higher mortality within the first year postadmission (54 vs. 37%), were less likely to receive expensive treatments, and were more frequently housed off-exhibit. On an average, parrots were found to have a short postadmission lifespan (median 356 days), with 92.5% of the birds dying within their first five years in captivity. The paper discusses the difficult dilemmas these incoming traffic-related animals pose to zoo management and official anti-traffic policies. PMID:20069544

Tomographic imaging of the equatorial and low-latitude ionosphere over central-eastern Brazil  

NASA Astrophysics Data System (ADS)

A four-dimensional time-dependent tomographic algorithm, named Multi Instrument Data Analysis System (MIDAS), is used to image the equatorial and low-latitude ionosphere over the central-eastern sides of the Brazilian territory. From differential phase data obtained by a chain of ground-based GPS receiver the total electron content (TEC) is estimated and then, together with a modeled ionosphere from International Reference Ionosphere (IRI) model, the electron density distribution is reconstructed and the parameters of the F2-peak layer are accessed from the images. This paper presents the first study of ionospheric tomography using real dual-frequency data from the Brazilian Network for Continuous GPS Monitoring (RBMC). Ionospheric F2-peak electron density (NmF2) accessed from the images are compared to concurrent measurements from three ionosondes installed across Brazil. One year of data during the solar maximum period from March/2001 to February/2002 is used to analyze the seasonal and hourly variation of the F2-layer peak density. The accuracy with which MIDAS images the electron density during geomagnetic quiet periods is investigated through its correlation and deviation with the ionosonde and IRI model data, respectively. The main aspects of the reconstruction results at the equatorial ionization anomaly (EIA) region over Brazil are highlighted and discussed.

Patterns in abundance and diversity of faecally dispersed parasites of tiger in Tadoba National Park, central India  

PubMed Central

Background Importance of parasites in ecological and evolutionary interactions is being increasingly recognized. However, ecological data on parasites of important host species is still scanty. We analyze the patterns seen in the faecal parasites of tigers in the Tadoba National Park, India, and speculate on the factors and processes shaping the parasite community and the possible implications for tiger ecology. Results The prevalence and intensities were high and the parasite community was dominated by indirect life cycle parasites. Across all genera of parasites variance scaled with the square of the mean and there was a significant positive correlation between prevalence and abundance. There was no significant association between different types of parasites. Conclusions The 70 samples analyzed formed 14 distinct clusters. If we assume each of the clusters to represent individual tigers that were sampled repeatedly and that resident tigers are more likely to be sampled repeatedly, the presumed transient tigers had significantly greater parasite loads than the presumed resident ones.

Assessment of the treatment of chronic hepatitis C in the state of Mato Grosso, central Brazil.  

PubMed

In Brazil, the treatment of hepatitis C virus (HCV) infection is funded by the national public health system (SUS). To evaluate treatment results in the state of Mato Grosso, central Brazil, we have consulted the files of the office of the State Department of Health responsible for supplying such medications. We obtained information on 232 treatments of 201 patients who underwent treatment in or prior to 2008. The study was conducted by reviewing medical records, making telephone calls and interviewing the assistant physicians. Thirty-nine patients (19.4%) had cirrhosis and HCV genotype 1 predominated (64.3%). Excluding patients with comorbidities or treatment without ribavirin we analysed 175 treatments (sustained virologic response occurred in 32.6% of cases). Twenty-six of these 175 were retreatments and the sustained virological response (SVR) rate among them was 30.8%; the SVR rate was 32.9% among those receiving treatment for the first time. The SVR rate of genotype 1 patients was 27.8%, whereas it was 37.5% in non-1 genotype patients. The adjusted multivariate analysis showed association of SVR with the absence of cirrhosis [odds ratio (OR): 7.7; confidence interval (CI) 95%: 2.5, 33.3], the use of pegylated interferon (OR: 5.8; CI 95%: 1.5, 21.4), non-1 genotype (OR: 5.3; CI 95%: 1.7, 16.7) and uninterrupted treatment (OR: 9.0; CI 95%: 3.3, 45.4). The SVR rates were similar to those found in other Brazilian studies about HCV, but lower than those found in national and international clinical trials. These data suggest that the treatments of chronic hepatitis C that are made available by SUS does not, under normal conditions, work as well as the original controlled studies indicated.

Spatial distribution of tropical wetlands in Central Brazil as influenced by geological and geomorphological settings  

NASA Astrophysics Data System (ADS)

Tropical wetlands in Central Brazil are located in savanna areas and are made up of more terrestrial-type wetlands - campo limpo úmido (grassland-type savanna), campo sujo úmido (shrub-type savanna), mata galeria (riverine forest); as well as more aquatic-type wetlands - vereda (valley-side marsh with palm groves of Mauritia flexuosa), várzea (backswamp), lake, and river. They are regulated by a seasonal climatic regime characterized by a wet-rainy season from October to March and then followed by a dry season. Underground water is abundant and rivers frequently overflow during the rainy season. Many of these wetlands which are protected by law are significant regulators of water quality. In order to predict tropical wetland function and draw up environmental management policies, it is important to understand how abiotic and biotic factors influence tropical wetland origin and spatial distribution. In this large-scale study we set out to investigate the influence that geological and geormorphological settings, i.e. geological substrates and geomorphological units, have on the spatial distribution of tropical wetlands in Central Brazil. Two watersheds, the Caiapó and Piracanjuba, were selected in order to carry out the study. They present different types of rock and unconsolidated surface materials. Planation surface, escarpment and steep slope, gentle slope, and aggradation are the dominant geomorphological units in the watersheds. Principal component analysis was conducted in order to determine the influence of the selected abiotic variables on the spatial distribution of tropical wetlands. The study showed that the presence of sedimentary and low-grade metamorphic rocks and planation surface strongly influence the spatial distribution of the more terrestrial-type wetlands. Geological and geomorphological settings explain about 60% of the variability in the spatial distribution of these wetland types. No clear effect of the abiotic variables selected was observed on the more aquatic-type wetlands. An association between stratified layers or planar geological surfaces, groundwater discharge zones, and slope breaks is suggested to explain the influence of the geological and geomorphological settings on the wetlands under review. The study demonstrated the importance of considering abiotic factors, not usually included in classification schemes, to further understand the spatial distribution of tropical wetlands.

Seismic characteristics of central Brazil crust and upper mantle: A deep seismic refraction study  

USGS Publications Warehouse

A two-dimensional model of the Brazilian central crust and upper mantle was obtained from the traveltime interpretation of deep seismic refraction data from the Porangatu and Cavalcante lines, each approximately 300 km long. When the lines were deployed, they overlapped by 50 km, forming an E-W transect approximately 530 km long across the Tocantins Province and western Sa??o Francisco Craton. The Tocantins Province formed during the Neoproterozoic when the Sa??o Francisco, the Paranapanema, and the Amazon cratons collided, following the subduction of the former Goia??s ocean basin. Average crustal VP and VP/VS ratios, Moho topography, and lateral discontinuities within crustal layers suggest that the crust beneath central Brazil can be associated with major geological domains recognized at the surface. The Moho is an irregular interface, between 36 and 44 km deep, that shows evidences of first-order tectonic structures. The 8.05 and 8.23 km s-1 P wave velocities identify the upper mantle beneath the Porangatu and Cavalcante lines, respectively. The observed seismic features allow for the identification of (1) the crust has largely felsic composition in the studied region, (2) the absence of the mafic-ultramafic root beneath the Goia??s magmatic arc, and (3) block tectonics in the foreland fold-and-thrust belt of the northern Brasi??lia Belt during the Neoproterozoic. Seismic data also suggested that the Bouguer gravimetric discontinuities are mainly compensated by differences in mass distribution within the lithospheric mantle. Finally, the Goia??s-Tocantins seismic belt can be interpreted as a natural seismic alignment related to the Neoproterozoic mantle domain. Copyright 2006 by the American Geophysical Union.

Anurans from a local assemblage in central Brazil: linking local processes with macroecological patterns.  

PubMed

Macroecological variables of Anuran species found in a local assemblage from Central Brazil (Silvânia, Goiás State) were linked to population dyamics statistics of these species. Geographical range size (GRS), body size, and species' midpoints were the macroecological variables investigated for those species found in the local assemblage and for all other species (105 in the total) found in the Cerrado biome. For each species found in the local assemblage, data on abundance was obtained. Using this data, local population variability as expressed by the coefficient of variation was estimated. Distribution of means, medians, maximum, variances, and skewness (g1), for both GRS and body size, estimated in the local assemblage were compared, using null models, with the data extracted from the overall Cerrado species pool. The results indicated a clear macroecological relationship between GRS and body size and a decrease in local abundance when distance between the locality analyzed and species midpoint increased. According to null models, both body size and GRS values measured in the local assemblage can be considered a random sample from the regional species pool (Cerrado region). Finally, a three-dimensional analysis using body size, GRS, and local population estimates (abundance and variability), indicated that less abundant and more fluctuating species fell near the lower boundary of the polygonal relationship between GRS and body size. Thus, macroecological results linked with local data on population dynamics supported the minimum viable population model. PMID:15195363

Landscape conservation genetics of Dipteryx alata ("baru" tree: Fabaceae) from Cerrado region of central Brazil.  

PubMed

In this paper random amplified polymorphic DNA (RAPD) was used to evaluate the degree of among-population differentiation and associated spatial patterns of genetic divergence for Dipteryx alata Vogel populations from Cerrado region of central Brazil, furnishing support for future programs of conservation of this species. We analyzed patterns of genetic and spatial population structure using 45 RAPD loci scored for 309 trees, sampled from five different regions with two populations each. Genetic structure analysis suggested that panmixia null hypothesis can be rejected, with significant among-population components of 15%. Hierarchical partition by Analysis of Molecular Variance (AMOVA) shows that 5% of genetic variation is within regions, whereas 10% of variation is among regions, and these results were confirmed by a Bayesian analyses on HICKORY. The Mantel correlogram revealed that this divergence is spatially structured, so that local populations situated at short geographic distances could not be considered independent units for conservation and management. However, genetic discontinuities among populations were found in the northwest and southeast parts of the study area, corresponding to regions of recent socio-economic expansion and high population density, respectively. Taking both geographic distances and genetic discontinuities into account it is possible to establish a group of population to be conserved, covering most of D. alata geographic distribution and congruent with previously established priority areas for conservation in the Cerrado region.

Molecular Characteristics of HIV Type 1 Infection Among Prisoners from Central Western Brazil  

PubMed Central

Abstract This study among antiretroviral-experienced prisoners from central western Brazil investigated mutations associated with secondary resistance to nucleoside/nonnucleoside reverse transcriptase inhibitors (NRTI/NNRTI), protease inhibitors (Stanford HIV-1 Resistance/International Aids Society Databases), and HIV-1 subtypes (REGA/phylogenetic analyses/SimPlot). Twenty-seven prisoners from three prisons (16 males and four females from Mato Grosso do Sul State and seven males from Goiás State) had HIV-1 protease and reverse transcriptase fragments sequenced after nested PCR. Median age was 35 years. Seven males and two females were intravenous drug users, three males referred homosexual practice. Resistance mutations were present in 37% (10/27): NRTI+NNRTI mutations (n=5), NRTI mutations (n=3), multidrug-resistant mutations (n=2). Subtype B (48%), subtype C (11%), B/F1, B/C, and F1/B/C recombinants (40.7%) were detected. Possible intraprison transmissions were identified: two intravenous drug user females (subtype C); two clusters among homosexual males (subtype B and B/F1). High resistance rate and possible intraprison transmission highlight the need for improved prevention, counseling, and treatment strategies for prisoners.

First molecular typing of cryptococcemia-causing cryptococcus in central-west Brazil.  

PubMed

Molecular epidemiology studies on cryptococcemia are limited. This study aimed to describe the clinical features of patients with bloodstream infections by Cryptococcus sp. in a public tertiary hospital in Mato Grosso do Sul, as well as identify the fungus' molecular type and determine its antifungal susceptibility. Molecular typing was performed using URA5 restriction fragment length polymorphism PCR, and antifungal susceptibility was determined by microdilution method standardized by the Clinical and Laboratory Standards Institute. Over 14 years, 48 patients were diagnosed with cryptococcemia. The majority (72.9 %) was male with a median age of 40 years; 81.3 % of the patients had HIV/AIDS and 72.9 % died. Cryptococcus neoformans was the most commonly isolated species (97.9 %). Molecular analysis identified the genotypes C. neoformans VNI (93.7 %), C. neoformans VNII (4.2 %), and Cryptococcus gattii VGII (2.1 %). In vitro, these fungi were not resistant to fluconazole, itraconazole, voriconazole, and amphotericin B. This is the first description of the molecular types of cryptococcemia agents in central-west Brazil. Its high lethality, especially in HIV-negative patients, suggests that early diagnosis and prompt antifungal therapy are crucial for a good clinical outcome. PMID:23846587

Spatial point analysis based on dengue surveys at household level in central Brazil  

PubMed Central

Background Dengue virus (DENV) affects nonimunne human populations in tropical and subtropical regions. In the Americas, dengue has drastically increased in the last two decades and Brazil is considered one of the most affected countries. The high frequency of asymptomatic infection makes difficult to estimate prevalence of infection using registered cases and to locate high risk intra-urban area at population level. The goal of this spatial point analysis was to identify potential high-risk intra-urban areas of dengue, using data collected at household level from surveys. Methods Two household surveys took place in the city of Goiania (~1.1 million population), Central Brazil in the year 2001 and 2002. First survey screened 1,586 asymptomatic individuals older than 5 years of age. Second survey 2,906 asymptomatic volunteers, same age-groups, were selected by multistage sampling (census tracts; blocks; households) using available digital maps. Sera from participants were tested by dengue virus-specific IgM/IgG by EIA. A Generalized Additive Model (GAM) was used to detect the spatial varying risk over the region. Initially without any fixed covariates, to depict the overall risk map, followed by a model including the main covariates and the year, where the resulting maps show the risk associated with living place, controlled for the individual risk factors. This method has the advantage to generate smoothed risk factors maps, adjusted by socio-demographic covariates. Results The prevalence of antibody against dengue infection was 37.3% (95%CI [35.5–39.1]) in the year 2002; 7.8% increase in one-year interval. The spatial variation in risk of dengue infection significantly changed when comparing 2001 with 2002, (ORadjusted = 1.35; p < 0.001), while controlling for potential confounders using GAM model. Also increasing age and low education levels were associated with dengue infection. Conclusion This study showed spatial heterogeneity in the risk areas of dengue when using a spatial multivariate approach in a short time interval. Data from household surveys pointed out that low prevalence areas in 2001 surveys shifted to high-risk area in consecutive year. This mapping of dengue risks should give insights for control interventions in urban areas.

2001-2010 glacier changes in the Central Karakoram National Park: a contribution to evaluate the magnitude and rate of the "Karakoram anomaly"  

NASA Astrophysics Data System (ADS)

We use Landsat images to quantify recent (2001 and 2010) glacier area coverage and its change within the recently established Central Karakoram National Park, CKNP, Northern Pakistan, including Baltoro and Biafo-Ispar glaciers, at Mt. K2 toe. Trends of climate variables (1980-2009) as provided by PMD of Pakistan for low altitude stations, are investigated, to assess possible effect of climate upon glaciers within the CKNP. The work was developed in fulfillment of the SEED and PAPRIKA projects, promoted and managed by the EvK2CNR Committee, aimed to promote social development in the CKNP area, and investigate water resources in upper Indus basin. We found substantially unchanged ice cover, which is consistent with recent the literature, suggesting the presence of the so called Karakoram Anomaly. The climate data display i) a slight decrease of Summer temperatures, possibly decreasing snow and ice melt, and ii) an increase of wet days during Winter, possibly increasing the number of snowfalls, and possibly of ice shielding via snow albedo. These joint effects, together with increasing debris coverage, may have in turn contributed to unchanged glacier area, in spite of the general warming trend. Our study highlights possible underlying mechanisms of the Karakoram Anomaly, and the need for further studies of climate variables at high altitudes, including snowfall accumulation, temperature and solar radiation, to understand more accurately glacier mass budgets and evolution in this area.

Adverse events and technical complaints related to central venous catheters marketed in Brazil  

PubMed Central

Aim The objective of this study was to critically analyze data of the National Notification System for Adverse Events and Technical Complaints (Notivisa) related to central venous catheters, through an evaluation of the description of notifications recorded between 2006 and 2009. Methods Notifications were categorized and evaluated to: (i) determine the number of adverse events and technical complaints, (ii) verify compliance with the classification criteria defined by the legislation, (iii) reclassify notifications, when necessary, in order for them to fit in with the legal definitions, (iv) verify registered companies in Brazil, (v) quantify the notifications according to the registered company and product lot, and (vi) identify the country of original of the notified product. Microsoft Excel(r) 2010 was used to categorize and systematize the data. Results Some conceptual errors and incomplete records were found. Altogether, 228 notifications of technical complaints and 119 of adverse events were identified. Some notifications on guidewires and broken catheters were reported which led to the necessity of duplicating some medical procedures and to the occurrence of lesions/lacerations of vessels and tissue injury. Forty-seven percent of companies presented at least one notification in Notivisa and in all, 38 product lots had more than one notification. Conclusion These data support a necessity for cooperation between all entities of the National Health Surveillance System to check compliance of this type of product and to properly report adverse events and technical complaints. It is also important to incorporate minimum standards for the management of technologies in health services, including in the acquisition of products and training of staff.

Prevalence and incidence of dengue virus and antibody placental transfer during late pregnancy in central Brazil  

PubMed Central

Background Maternal dengue antibodies are considered to play a significant role in dengue pathogenesis among infants. Determining the transplacental specific antibody transfer is invaluable for establishing the optimal vaccination age among infants in endemic regions. Methods We conducted a cross-sectional study among pairs of maternal and corresponding umbilical cord blood samples in public hospitals. The prevalence and incidence of dengue infection were determined in 505 pairs of pregnant women and neonates during a large outbreak (2009–2010) in central Brazil. The women were interviewed at late pregnancy to assess current or past symptoms of dengue. All parturients and their neonates were screened using Dengue IgG Indirect ELISA (Panbio) to assess previous dengue exposure. A semi-quantitative measurement of the IgG antibody expressed by the index ratio was calculated using optical density (OD) values according to the manufacturer’s instructions. The studied population of parturients and their offspring was also screened for recent dengue infection by the Dengue IgM-capture ELISA (Panbio). Those participants with history of fever and two or more symptoms of dengue at least 10 days before the delivery were also tested for the dengue NS1 antigen using the Dengue Early ELISA (Panbio) and RT-PCR. Results The mean maternal age was 25.8 (SD?=?6.4), and 83.6% of deliveries were between 37 and 41 weeks. Approximately half of the 505 women and neonates were IgG-seropositive, yielding 99.3% co-positive mother-child frequency of antibody transfer (Kappa?=?0.96). The incidence of dengue infection was 2.8% (95% CI 1.4–4.4%) among the women considering 14 IgM-positive results and one DENV2 detected by RT-PCR. The dengue NS1 antigen was undetectable in the matched pairs. Conclusion This study provides critical data on the prevalence of transplacental transferred maternal-infant anti-dengue antibodies and incidence of infection. The design of future vaccine trials should consider diverse regional epidemiological scenarios.

Nitrous oxide fluxes and nitrogen cycling along a pasture chronosequence in Central Amazonia, Brazil  

NASA Astrophysics Data System (ADS)

We studied nitrous oxide (N2O) fluxes and soil nitrogen (N) cycling following forest conversion to pasture in the central Amazon near Santarém, Pará, Brazil. Two undisturbed forest sites and 27 pasture sites of 0.5 to 60 years were sampled once each during wet and dry seasons. In addition to soil-atmosphere fluxes of N2O we measured 27 soil chemical, soil microbiological and soil physical variables.

Soil N2O fluxes were higher in the wet season than in the dry season. Fluxes of N2O from forest soils always exceeded fluxes from pasture soils and showed no consistent trend with pasture age. At our forest sites, nitrate was the dominant form of inorganic N both during wet and dry season. At our pasture sites nitrate generally dominated the inorganic N pools during the wet season and ammonium dominated during the dry season. Net mineralization and nitrification rates displayed large variations. During the dry season net immobilization of N was observed in some pastures. Compared to forest sites, young pasture sites (?2 years) had low microbial biomass N and protease activities. Protease activity and microbial biomass N peaked in pastures of intermediate age (4 to 8 years) followed by consistently lower values in older pasture (10 to 60 years). The C/N ratio of litter was low at the forest sites (~25) and rapidly increased with pasture age reaching values of 60-70 at pastures of 15 years and older.

Nitrous oxide emissions at our sites were controlled by C and N availability and soil aeration. Fluxes of N2O were negatively correlated to leaf litter C/N ratio, NH4+-N and the ratio of NO3--N to the sum of NO3--N + NH4+-N (indicators of N availability), and methane fluxes and bulk density (indicators of soil aeration status) during the wet season. During the dry season fluxes of N2O were positively correlated to microbial biomass N, ?-glucosidase activity, total inorganic N stocks and NH4+-N. In our study region, pastures of all age emitted less N2O than old-growth forests, because of a progressive decline in N availability with pasture age combined with strongly anaerobic conditions in some pastures during the wet season.

Lithospheric and sublithospheric anisotropy beneath central-southeastern Brazil constrained by long period magnetotelluric data  

NASA Astrophysics Data System (ADS)

Electric anisotropy calculated from geoelectric strikes of magnetotelluric (MT) data and seismic anisotropy derived from shear-wave splitting parameters are jointly analyzed to estimate the degree and orientation of strain in the subcontinental mantle of central-southeastern Brazil. High-quality long-period MT soundings are available at 90 sites concentrated along four profiles at the southwestern and southern borders of the Paleoproterozoic-Archean São Francisco craton. This data set is complemented by a previous study of SKS and SKKS splitting measurements available at more than 40 sites covering a slightly wider region. For this study, the MT data were processed with modern techniques, including recovery of the undistorted EM field polarizations through correction of static shift and phase mixing due to galvanic distortions. Three-dimensional forward modelling of MT and GDS (geomagnetic depth soundings) transfer functions supports interpretation of deep electrical anisotropy in the region. Magnetotelluric phase responses of orthogonal propagation modes present slight splitting at long periods for most of the sites, indicative of overall electrically low mantle anisotropy to depths greater than 250 km. The electrical strike azimuths are parallel to the fast NW directions of shear-wave splitting along the southern borders of the São Francisco craton, suggesting that the seismic anisotropy also resides within the same depth range. Since this direction is very different from that of present-day South American westward absolute plate motion, it is inferred that no significant lateral mantle flow or deformation related to the plate motion is observed under the study area, either because it is absent or the rigid lithosphere is much thicker than expected. To explain the prevailing electric and seismic common direction it is suggested that a mechanical coupling between lithospheric and sublithospheric mantle exists. A relic strain, possibly resulting from ancient continental collision processes, is interpreted to have induced a general alignment of olivine down to mantle depths beneath the continental rigid plate. The observed slightly enhanced conductive texture could be associated with hydrogen diffusion along the aligned olivine a-axis, especially within mantle patches subjected to metasomatic processes. The coincidence of mantle strikes with the trend of surface deformation pattern also suggests that crust, lithospheric and sublithospheric upper-mantle have deformed and translated coherently, preserving the regional NW direction since the tectono-thermal event responsible for the deformation. Distinct electric azimuths from the general NW trend are observed in regions probably perturbed by Cretaceous rift-related intraplate magmatism and in zones of complex deep structures produced by superposed nearly simultaneous oblique Neoproterozoic collisions in the southeast of the São Francisco craton.

Brazil's population in 1985 was 135 million, with an annual growth rate (1982) of 2.3%. The infant mortality rate (1981) was 92/1000, and life expectancy stood at 62.8 years. 76% of the adult population was literate. Brazil is a federal republic which recognizes 5 political parties. 55% of the population is Portuguese, Italian, German, Japanese, African, or American Indian; 38% is white. Of the work force of 50 million, 35% are engaged in agriculture, 25% work in industry, and 40% are employed in services. Trade union membership totals 6 million. The agricultural sector accounts for 12% of the GDP and 40% of exports. Brazil is largely self-sufficient in terms of food. The GDP was US$218 billion in 1984, with an annual growth rate of 4%. Per capita GDP was US$1645. Brazil's power, transportation, and communications systems have improved greatly in recent years, providing a base for economic development. High inflation rates have been a persistent problem. PMID:12178118

Seroprevalence of Toxoplasma gondii in free-living Amazon River dolphins (Inia geoffrensis) from central Amazon, Brazil.  

PubMed

Toxoplasma gondii is an important pathogen in aquatic mammals and its presence in these animals may indicate the water contamination of aquatic environment by oocysts. Serum samples from 95 free-living Amazon River dolphins (Inia geoffrensis) from the Mamirauá Sustainable Development Reserve (RDSM), Tefé, Amazonas, Central Amazon, Brazil were tested for T. gondii antibodies using the modified agglutination test (MAT). Antibodies (MAT ? 25) to T. gondii were found in 82 (86.3%) dolphins with titers of 1:25 in 24, 1:50 in 56, and 1:500 in 2. Results suggest a high level contamination of the aquatic environment of the home range of these animals. PMID:21764516

The occurrence and prevalence of Metacuterebra apicalis (Diptera: Cuterebridae) in natural populations of Oryzomys subflavus, Bolomys lasiurus, and Thalpomys cerradensis (Rodentia: Muridae) from August 1990 to July 1992 in the cerrado, a common savanna-like vegetation type of central Brazil, are reported. An increase in bot infection in the 3 rodent species between October 1991 and July 1992 without correlation to precipitation was detected. The prevalence was lower than in neotropical forest formations. Mean intensity was 1.3 bots (range 1-2) for T. cerradensis and 1 bot for B. lasiurus and O. subflavus. This is the first record of T. cerradensis as host of bot flies. PMID:8410558

Ritual use of plants with possible action on the central nervous system by the Kraho Indians, Brazil.  

PubMed

The aim of the present study was to document the use of plants, probably acting on the central nervous system (CNS), in rituals carried out by the Kraho Indians, who occupy the cerrado biome in the central region of Brazil. The 2 years of fieldwork were guided by methods of anthropology and botany. The local shamans have indicated 286 formulas, consisting of 138 plant species in 50 uses that could be associated with some type of action on the CNS; of which 98 formulas, 87 plants and 25 uses, appear to involve psychoactive properties, such as: 'to get slow', 'stimulant effect', 'to calm down', 'to enhance memory', 'to reduce anxiety' and 'to induce sleep'. Phytochemical and pharmacological literature data were queried to establish any correlation between indigenous knowledge and scientific indications, for each one of the 138 plant species. Studies were available for 11 of these plants; and for two of them, scientific data coincided with indigenous information. PMID:15852494

Molecular and geographic analyses of vampire bat-transmitted cattle rabies in central Brazil  

PubMed Central

Background Vampire bats are important rabies virus vectors, causing critical problems in both the livestock industry and public health sector in Latin America. In order to assess the epidemiological characteristics of vampire bat-transmitted rabies, the authors conducted phylogenetic and geographical analyses using sequence data of a large number of cattle rabies isolates collected from a wide geographical area in Brazil. Methods Partial nucleoprotein genes of rabies viruses isolated from 666 cattle and 18 vampire bats between 1987 and 2006 were sequenced and used for phylogenetic analysis. The genetic variants were plotted on topographical maps of Brazil. Results In this study, 593 samples consisting of 24 genetic variants were analyzed. Regional localization of variants was observed, with the distribution of several variants found to be delimited by mountain ranges which served as geographic boundaries. The geographical distributions of vampire-bat and cattle isolates that were classified as the identical phylogenetic group were found to overlap with high certainty. Most of the samples analyzed in this study were isolated from adjacent areas linked by rivers. Conclusion This study revealed the existence of several dozen regional variants associated with vampire bats in Brazil, with the distribution patterns of these variants found to be affected by mountain ranges and rivers. These results suggest that epidemiological characteristics of vampire bat-related rabies appear to be associated with the topographical and geographical characteristics of areas where cattle are maintained, and the factors affecting vampire bat ecology.

Serological markers and risk factors related to hepatitis B virus in dentists in the Central West region of Brazil  

PubMed Central

The hepatitis B virus (HBV) has been considered the major occupational risk agent for dentists. The Central West region of Brazil is considered an intermediate endemic pattern area, but currently there is no information about the HBV prevalence in dentists of Goiânia, Goiás. This study aimed at the detection of the HBV infection rate and risk factors for dentists of Goiânia and the comparison of the obtained data with the general population and other groups. A randomized sample of 680 professionals participated in this study. All dentists gave written consent for the procedure and filled out a questionnaire about risk factors. The HBV serological markers were analyzed using ELISA test and the presence of anti-HBc was observed in 41 (6.0%) of the dentists. None of them was HBsAg positive. Significant relationships with HBV positivity were observed with gender, the time working as a dentist and the use of incomplete personal protective equipment (PPE). The HBV prevalence found in this group of dentists was lower than the endemic pattern of the general population, other health care workers of the region and the dentists from other regions in Brazil. These results may indicate a positive impact of vaccination considering the high adherence of the dentists to the immunization program (98.4%). Finally, the use of complete PPE by the majority as well as other standard precautions recommended for health care workers could be responsible for the low HBV seroprevalence.

Evolutionary Relationships of the Triatoma matogrossensis Subcomplex, the Endemic Triatoma in Central-Western Brazil, Based on Mitochondrial DNA Sequences.  

PubMed

Abstract. The phylogenetic relationships among species of Triatoma matogrossensis subcomplex (T. baratai, T. guazu, T. matogrossensis, T. sordida, T. vandae, and T. williami) was addressed by using fragments of cytochrome oxidase I (COI), 16S rDNA (16S), and cytochrome b (Cytb) through Bayesian and parsimony analyses. We did not recover a monophyletic T. matogrossensis subcomplex, and their members were found clustered in three strongly supported clades, as follows: i) T. jurbergi + T. matogrossensis + T. vandae + T. garciabesi + T. sordida; ii) with T. guasayana as the sister group of clade (i); and iii) T. williami + T. guazu, however not closely related to the clade formed by the previously mentioned species. The other two endemic species from Central-Western Brazil, T. baratai and T. costalimai, were not recovered with strong clade support as related to other members of this subcomplex. Results call for a further revision in the classification of the subcomplexes within the genus Triatoma. PMID:24002487

Characteristics of Mesospheric Gravity Waves Observed in the Central Region of Brazil  

NASA Astrophysics Data System (ADS)

Gravity waves observations were carried out at Palmas (10.16o S, 48.26o W) Brazil, between September 2007 and December 2008, using an all-sky airglow imager to measure the OH emis-sion. The gravity waves were divided in two groups following they morphology as band and ripples type waves. The main characteristics of the band type waves are: horizontal wavelength between 10-35 km; observed period raging from 5 to 25 minutes; observed phase speed between 5-60 m/s. Preferential propagation directions of the bands are northward and southward, show-ing a clear anisotropy. For the ripples the main wave parameters are: horizontal wavelength ranging between 5 and 15 km; observed period mainly distributed between 5 and 15 minutes and horizontal phase velocity from 5 to 30 m/s. The ripples showed the same anisotropy as in the preferential propagation direction as the band type waves. The gravity wave characteristics observed at Palmas were compared with other observations carried out in Brazil, showing simi-lar features. In order to explain the seasonal variation of the wave propagation direction, maps of Outgoing Longwave Radiation (ORL) were used to locate regions with intense deep con-vection (OLR < 220 W.m-2 ) in the lower atmosphere. During summer and autumn the wave sources regions are well correlated with deep convection areas located at west and northwest of Palmas.

Formic and acetic acid over the central Amazon region, Brazil 1. Dry season  

SciTech Connect

We have determined the atmospheric concentrations of formic and acetic acid in the gas phase, in aerosols, and in rain during the dry season (July--August 1985) in the Amazonia region of Brazil. At ground level the average concentrations of gas phase formic and acetic acid were 1.6 +- 0.6 and 2.2 +- 1.0 ppb, respectively. The diurnal behavior of both acids at ground level and their vertical distribution in the forest canopy point to the existence of vegetative sources as well as to production by chemical reactions in the atmosphere. Dry deposition of the gaseous acids appears to be a major sink. The concentrations of formic and acetic acid in the gas phase were about 2 orders of magnitude higher than concentrations of the corresponding species in the atmospheric aerosol. About 50--60%/sub 0/ of the aerosol (total) formate and acetate were in the size fraction below 1.0 ..mu..m diameter.

Diversity of sandflies (Psychodidae: Phlebotominae) captured in sandstone caves from Central Amazonia, Brazil.  

PubMed

In the present paper we describe the diversity of phlebotomine sandflies collected in three sandstone caves in the municipality of Presidente Figueiredo, state of Amazonas, Brazil. The phlebotomines were captured during 2006 with CDC light traps. Guano samples from inside the Gruta Refúgio do Maruaga were collected to investigate the presence of immature specimens. A total of 2,160 adult phlebotomines representing 15 species were captured. Pintomyia pacae was the dominant species in Gruta dos Animais (1,723 specimens) and Gruta dos Lages (50 specimens) and Deanemyia maruaga new comb (280 specimens) was the dominant species in Gruta Refúgio do Maruaga. A total of 18 guano samples were collected and seven of these samples included immature specimens. A total of 507 immature specimens were captured; 495 of these specimens were larvae and 12 were pupae. The presence of paca (Agouti paca) footprints near Gruta dos Animais and Gruta dos Lages suggests the association of Pi. pacae with this rodent. This finding may explain the abundance of Pi. pacae in these locations, while the species is relatively rare in the forest. Deanemyia maruaga is a cave species that uses guano to breed during its immature stages. Adult specimens of this species are apparently parthenogenetic and autogenous and represent the second record of parthenogenesis for the subfamily Phlebotominae. PMID:21655825

Vulnerability to AIDS among the elderly in an urban center in central Brazil  

PubMed Central

OBJECTIVE: As the world population ages with an improved quality of life and sexual longevity, the prevalence of AIDS is rising among the elderly. The purpose of this study was to estimate the vulnerability to AIDS among individuals attending senior community centers in Campo Grande, Mato Grosso do Sul, Brazil. METHOD: This descriptive, exploratory investigation included 329 subjects selected in a probabilistic manner. Individuals with scores on the Mini-Mental State Examination indicating cognitive impairment were excluded from the analyses. Barthel's and Lawton's functional assessment scales were applied. Interviews were conducted to evaluate the presence of cognitive and behavioral factors associated with HIV transmission. RESULTS: Most subjects were non-dependent, fell within the 60- to 69-year age bracket and were female. A majority of individuals reported having knowledge about AIDS and were aware that the elderly are vulnerable to the disease. More than a quarter (26.9%) of the sample reported previous HIV testing. No participants reported drug use, homosexual orientation, or alcohol abuse. A minority of participants reported using medication for erectile dysfunction. Casual and multiple partners accounted for 12% and 34% of reported intercourse experiences, respectively. Condom use was reported by 14% of respondents. CONCLUSION: Unprotected sex was the primary factor accounting for vulnerability to AIDS among the elderly.

Genetic parameters for type classification of Nelore cattle on central performance tests at pasture in Brazil.  

PubMed

The objective of this study was to characterize Nelore cattle on central performance tests in pasture, ranked by the visual classification method EPMURAS (structure, precocity, muscle, navel, breed, posture, and sexual characteristics), and to estimate genetic and phenotypic correlations between these parameters, including visual as well as production traits (initial and final weight on test, weight gain, and weight corrected for 550 days). The information used in the study was obtained on 21,032 Nelore bulls which were participants in the central performance test at pasture of the Brazilian Association for Zebu Breeders (ABCZ). Heritabilities obtained were from 0.19 to 0.50. Phenotypic correlations were positive from 0.70 to 0.97 between the weight traits, from 0.65 to 0.74 between visual characteristics, and from 0.29 to 0.47 between visual characteristics and weight traits. The genetic correlations were positive ranging from 0.80 to 0.98 between the characteristics of structure, precocity and musculature, from 0.13 to 0.64 between the growth characteristics, and from 0.41 to 0.97 between visual scores and weight gains. Heritability and genetic correlations indicate that the use of visual scores, along with the selection for growth characteristics, can bring positive results in selection of beef cattle for rearing on pasture.

Evaluation of Paracoccidioides brasiliensis infection by gp 43 intradermal test in rural settlements in Central-West Brazil.  

PubMed

Epidemiological studies of paracoccidioidomycosis have been based on surveys achieved with intradermal tests, and paracoccidioidin is the most common antigen used in most cases. The glycoprotein of 43-kDa (gp43) has been used in intradermal tests. It is the most antigenic component of Paracoccidioides brasiliensis, and it provides greater specificity to evaluate infection for this fungus. In this study, the prevalence of P. brasiliensis infection was estimated with intradermal tests involving gp43 for 695 people in rural Central-West Brazil. The infection rate was 45.8 % (95 % CI = 42.1-49.5), and the average age of those infected was 45.8 ± 18.2 years. The prevalence did not show gender-based differences but increased with age. The results demonstrate the importance of P. brasiliensis infection in rural settlements and the early exposure of children in the region to the fungus. Despite the high antigenicity and specificity of gp43, its usage must be standardized, so that epidemiological surveys will be comparable and more accurately reflect P. brasiliensis infection in endemic areas.

Paleomagnetism of the Santa Fé Group, central Brazil: Implications for the late Paleozoic apparent polar wander path for South America  

NASA Astrophysics Data System (ADS)

Paleomagnetic and rockmagnetic data are reported for the Floresta Formation (Santa Fé Group) of the Sanfranciscana Basin, central Brazil. This formation represents the Permo-Carboniferous glacial record of the basin and comprises the Brocotó (diamictites and flow diamictites), Brejo do Arroz (red sandstones and shales with dropstones and invertebrate trails), and Lavado (red sandstones) members, which crop out near the cities of Santa Fé de Minas and Canabrava, Minas Gerais State. Both Brejo do Arroz and Lavado members were sampled in the vicinities of the two localities. Alternating field and thermal demagnetizations of 268 samples from 76 sites revealed reversed components of magnetization in all samples in accordance with the Permo-Carboniferous Reversed Superchron. The magnetic carriers are magnetite and hematite with both minerals exhibiting the same magnetization component, suggesting a primary origin for the remanence. We use the high-quality paleomagnetic pole for the Santa Fé Group (330.9°E 65.7°S; N = 60; ?95 = 4.1°; k = 21) in a revised late Carboniferous to early Triassic apparent polar wander path for South America. On the basis of this result it is shown that an early Permian Pangea A-type fit is possible if better determined paleomagnetic poles become available.

A study of weeds as potential inoculum sources for a tomato-infecting begomovirus in central Brazil.  

PubMed

Tomato severe rugose virus (ToSRV) is the most important begomovirus species in Brazilian tomato production. Many weeds are associated with tomato, and some are hosts of begomoviruses. Only one species of weed, Nicandra physaloides, has been found to be infected with ToSRV. In this study, four weed species were investigated for their capacity to be infected by ToSRV and serve as a potential source of inoculum for tomato. Begomoviruses from naturally infected Crotalaria spp., Euphorbia heterophylla, N. physaloides, and Sida spp. were successfully transferred to tomato plants by biolistic inoculation. ToSRV was the major virus transferred to tomato. In contrast, other begomoviruses were transferred to weeds, such as Sida micrantha mosaic virus and Euphorbia yellow mosaic virus. Furthermore, a new strain of Sida micrantha mosaic virus is reported. We also confirmed that Crotalaria spp., E. heterophylla, and Sida spp. are infected with ToSRV but at low viral titers and in mixed infections with weed-infecting begomoviruses. Thus, it was demonstrated that weeds are potential sources of ToSRV for tomato in central Brazil. PMID:23489523

Upper-mantle seismic structure beneath SE and Central Brazil from P- and S-wave regional traveltime tomography  

NASA Astrophysics Data System (ADS)

We present models for the upper-mantle velocity structure beneath SE and Central Brazil using independent tomographic inversions of P- and S-wave relative arrival-time residuals (including core phases) from teleseismic earthquakes. The events were recorded by a total of 92 stations deployed through different projects, institutions and time periods during the years 1992-2004. Our results show correlations with the main tectonic structures and reveal new anomalies not yet observed in previous works. All interpretations are based on robust anomalies, which appear in the different inversions for P- and S-waves. The resolution is variable through our study volume and has been analyzed through different theoretical test inversions. High-velocity anomalies are observed in the western portion of the São Francisco Craton, supporting the hypothesis that this Craton was part of a major Neoproterozoic plate (San Franciscan Plate). Low-velocity anomalies beneath the Tocantins Province (mainly fold belts between the Amazon and São Francisco Cratons) are interpreted as due to lithospheric thinning, which is consistent with the good correlation between intraplate seismicity and low-velocity anomalies in this region. Our results show that the basement of the Paraná Basin is formed by several blocks, separated by suture zones, according to model of Milani & Ramos. The slab of the Nazca Plate can be observed as a high-velocity anomaly beneath the Paraná Basin, between the depths of 700 and 1200 km. Further, we confirm the low-velocity anomaly in the NE area of the Paraná Basin which has been interpreted by VanDecar et al. as a fossil conduct of the Tristan da Cunha Plume related to the Paraná flood basalt eruptions during the opening of the South Atlantic.

Relationships among vegetation, geomorphology and hydrology in the Bananal Island tropical wetlands, Araguaia River basin, Central Brazil  

NASA Astrophysics Data System (ADS)

The Bananal Plain spreading on the Middle Araguaia River basin in Central Brazil at the Cerrado-Amazonia ecotone is a unique system that sustains the largest seasonal wetlands of the Cerrado biome. The huge Bananal Plain is an intracratonic sedimentary basin filled with Pleistocene sediments of the Araguaia formation. Covering approximately two million hectares, the Bananal Island is a major geomorphologic feature of the Bananal plain. Fieldwork and the analysis of a temporal series of MODIS-VI and Landsat ETM images allowed us to discriminate Cerrado phyto-physiognomies on the Bananal Island. Maps of vegetation and geomorphologic units were created, and from the correlation between landforms and vegetation types we identified morpho-vegetation units.Our approach allowed us to postulate that Pleistocene landforms strongly influence, if not dominate, the distribution of vegetation units.For example, the distribution of current gallery forest is not only controlled by active floodplains, but also by alluvial belts abandoned by avulsion. Additionally, arboreal Cerrado vegetation is supported by laterite developed on the sediments of the Araguaia Formation. Some of these inactive landforms are in part modified by the present day geomorphologic processes and colonized by successional vegetation that varies from alluvial forest to Cerrado.Characterized by a very flat landscape with a hindered drainage, the muddy sediments of the Araguaia Formation and the high seasonal rainfall favor the development of regional seasonal wetlands.The Bananal plain is a key area for understanding the Quaternary climatic and biogeographic changes in tropical South America. The control exerted by relict Quaternary landforms on the current vegetation units demonstrates the strong links between geomorphologic aspects of the landscape and ecological patterns. This multidisciplinary approach provides a better understanding of the biogeographic patterns in the Cerrado-Amazon ecotone, which is useful for identifying and designing areas for conservation.

Water budgets, water quality, and analysis of nutrient loading of the Winter Park chain of lakes, central Florida, 1989-92  

USGS Publications Warehouse

The Winter Park chain of lakes (Lakes Maitland, Virginia, Osceola, and Mizell) has a combined area of about 900 acres, an immediate drainage area of about 3,100 acres, and mean depths ranging from 11 to 15 feet. The lakes are an important recreational resource for the surrounding communities, but there is concern about the possible effects of stormwater runoff and seepage of nutrient-enriched ground water on the quality of water in the lakes. The lakes receive water from several sources: rainfall on lake surfaces, inflow from other surface-water bodies, stormflow that enters the lakes through storm drains or by direct runoff from land adjacent to the lakes and ground-water seepage. Water leaves the lakes by evaporation, surface outflow, and ground-water outflow. Of the three, only surface outflow can be measured directly. Rainfall, surface inflow and outflow, and lake-stage data were collected from October 1, 1989, to September 30, 1992. Stormflow, evaporation and ground-water inflow and outflow were estimated for the 3 years of the study. Ground-water outflow was calculated by evaluating the rate of lake-stage decline during dry periods. Estimated ground-water outflow was compared to downward leakage rates estimated by ground-water flow models. Lateral ground-water inflow from surficial sediments was calculated as the residual of the flow budget. Flow budgets were calculated for the 3 years of the study. In water year 1992 (a year with about average rainfall), inflow consisted of rainfall, 48 inches; stormflow, 15 inches; surface inflow, 67 inches; and ground water, 40 inches. The calculated outflows were evaporation, 47 inches; surface outflow, 90 inches; and ground water, 33 inches. Water-quality data also were used to calculate nutrient budgets for the lakes. Bimonthly water samples were collected from the lakes and at surface inflow and outflow sites, and were analyzed for physical characteristics, dissolved oxygen, pH, specific conductance, major ions, the nutrients nitrogen and phosphorus, and chlorophyll (collected at lake sites only). Specific conductance ranged from about 190 to 230 microsiemens per centimeter at 25 degrees Celsius in Lakes Maitland, Virginia and Osceola and from about 226 to 260 microsiemens per centimeter at 25 degrees Celsius in Lake Mizell. The median concentrations of total ammonia-plus-organic nitrogen in all the lakes ranged from 0.79 to 0.99 milligrams per liter. Median total phosphorus concentrations ranged from less than 0.02 to 0.20 milligrams per liter. Stormwater samples were collected for 17 storms at one storm-drain site and 16 storms at another storm-drain site on Lake Osceola. Median total nitrogen concentrations at the sites were 2.23 and 3.06 milligrams per liter and median total phosphorus concentrations were 0.34 and 0.40 milligrams per liter. The water quality in the Winter Park lakes generally is fair to good, based on a trophic-state index used by the Florida Department of Environmental Protection for assessing the tropic state of Florida lakes. This index was determined from median total nitrogen, total phosphorus, and chlorophyll-a concentrations, and median Secchi-disk transparency for all lakes for the period September 1989 to June 1992. Based on a one-time sampling of 20 sites around the lakes, surficial ground-water quality is highly variable. Nutrient concentrations were highly variable and could not be correlated to the proximity of septic tanks. Fertilizer probably is the primary source of nutrients in the surficial ground water. Nutrient budgets were calculated for the lakes for the 3 years of the study. The most variable source of nutrient loading to the lakes is stormwater. Nutrient-loading modeling indicates that reduction of nutrients in stormflow probably would improve lake-water quality. However, even with complete removal of nitrogen and phosphorus from stormwater, the lakes might still be mesotrophic with respect to both nutrients during periods of below ave

Airborne geophysical surveys in the north-central region of Goias (Brazil): implications for radiometric characterization of tropical soils.  

PubMed

Progress obtained in analysis aerogammaspectrometric and aeromagnetic survey data for the north-central region of the state of Goias (Brazil) are presented. The results obtained have allowed not only determination of the abundances of naturally radioactive elements but also new insights into the processes that determine the radiometric characteristics of the main soil types. There are indications that the radioelement abundances of soils are not only related to their physical properties, but also chemical characteristics of source rocks from which they are derived. For example, oxisol soils derived from the felsic source rocks of the Mara Rosa and Green stone belts have equivalent uranium (eU) values higher than 1.7 ppm, while those derived from source rocks of the relatively more basic Uruaçu Group and sediment sequences of Proterozoic age are characterized by eU contents of less than 1 ppm. Oxisol soils of the Median massif, ultisol soils of the Paranoá, Canastra and Araxá Groups, cambisol soils of the Araí Group and plintosol soils of the Bambuí Group constitute an intermediate class with eU contents in the range of 1-1.3 ppm. Equivalent thorium abundances of soil types display similar trends, the range of variation being 4-16 ppm. Potassium abundances on the other hand are rather uniform with values in the range of 1-1.3%, the only exception being the sedimentary sequences of Proterozoic age, which has a mean value of 0.7%. These observations have been considered as indicative of characteristic features of tropical soils in the study area. In this context, we point out the possibility of using results of aerogammaspectrometry surveys as a convenient complementary tool in identifying geochemical zoning of soils in tropical environments. The ratios of eU/K are found to fall in the range of 1-1.7, which is typical of common soils. The ratios of eTh/K exhibit a relatively wide interval, with values in the range of 4-16. The ratios of eTh/eU are found to have values in the range of 2-12. Also, there appears to be a rather reasonable association between the spatial distributions of positive anomalies of the radioelement ratios with the lineaments derived from the vertical derivative of the magnetic field. The map of the analytic signal of the magnetic field also reveals a similar association. Such associations imply that the processes which determine evolutionary trends of soil types are somehow related to the events that control the development of structural features in subsurface layers.

Epidemiology of hepatitis B virus infection in first-time blood donors in the southwestern region of Goi?s, central Brazil  

PubMed Central

Introduction Little is known about the epidemiology of hepatitis B virus (HBV) infection in populations from inner cities, especially in Central Brazil. Thus the objective of this study was to estimate the prevalence of HBV infection, and to analyze the factors associated with HBV infection, in a population of first-time blood donors in the southwestern region of Goiás, Central Brazil. Methods A total of 984 individuals were interviewed and gave blood samples to detect serological markers of HBV (HBsAg, anti-HBs, and anti-HBc) by enzyme linked immunosorbent assays. Results An overall prevalence of 6.9% was found for HBV, with constituent prevalence rates of 3.6% and 11.6%, in subjects classified as fit and unfit to donate blood according the epidemiological screening, respectively. Only three individuals were positive for anti-HBs alone, suggesting previous vaccination against HBV. The variables of prior blood transfusion (OR = 2.3), tattoo/piercing (OR = 2.1), illicit drug use (OR = 2.3), sex with a partner with hepatitis (OR = 14.7), and history of sexually transmitted diseases (OR = 2.9) were independently associated with HBV-positivity. These data suggested a low endemicity of hepatitis B in the studied population. Conclusion The findings of low hepatitis B immunization coverage and the association of hepatitis B with risky behavior highlight that there is a need to intensify hepatitis B prevention programs in the southwest region of Goiás.

New apatite fission-track data reflecting the landscape evolution using the example of the southeastern passive continental margin in Central Brazil  

NASA Astrophysics Data System (ADS)

Low-temperature thermochronolgy like AFT yield a well established tool to understand and reconstruct the rift to post-rift evolution of the passive continental margin in Brazil. The aim of the study is to quantify the temperature, exhumation, uplift, and long-term dynamic evolution of the topography of the southeastern passive continental margin in the states of Paraná and Santa Catarina (Central Brazil) along different transects. The working area shows the active evolution since the Early Cretaceous with altitudes up to 1400 m a.s.l and partly deep incised valleys. The first transect crosses the Ponta Grossa Arch with Devonian to Jurassic sediments in an NE-SW direction from the escarpment (Escarpa Devoniana) of the Serra Mantiquera in the NE to the escarpment in the SE built up of the overlying Early Cretaceous flood basalts of the Serra Urtigueira. The second transect drops down perpendicular to the coast where the eastern escarpment of the Serra Geral (up to 1400 m a.s.l) reaches nearly the coast. The highlands consist of Cretaceous flood basalts whereas the coastal lowlands constist of Precambrian metamorphic and intrusive rocks. Previous apatite fission-track data of the states of Parana and Santa Catarina provide ages between 144 (5) Ma (Gallgher et al., 1994) and 25 (1.8) Ma (Franco-Magalhaes, A.O.B., subm.) and show different post-rift reactivation from the Cretaceous to the Paleogene. But none of the studies indicate a clear relationship between age distribution and topography or age distribution and stratigraphic age. This study is based on samples taken along the transects within the working area. The results will provide new insigths into the evolution of the southeastern passive continental margin in Central Brazil concerning the thermal, exhumation, and uplift history of the Brazilian passive continental margin.

The North Park, South Park, and Raton Basins of Colorado: An Integrated Geophysical Study  

NASA Astrophysics Data System (ADS)

North and South Park are intermontane basins in north-central Colorado and the Raton Basin is in south-central Colorado. These basins were formed in the compressive environment of the Late Cretaceous-Early Tertiary Laramide orogeny. Other structural events affecting the region of these basins include the Pennsylvanian-Permian Ancestral Rocky Mountain orogeny and Neogene extension in the case of the Raton Basin. The purpose of this study is to determine the structure and origin of the Park and Raton Basins and integrate the results with other studies carried out by the CD-ROM (Continental Dynamics-Rocky Mountain) project. Gravity and magnetic data have been modeled for North and South Park resulting in a series of filtered (smoothed and bandpassed) maps and 2.5-D models. The filtered gravity maps display a gravity low in the North Park basin due to Tertiary fill. A regional gravity low in the South Park area is associated with the Colorado Mineral Belt. The 2.5-D model for North Park reflects the synclinal nature of the basin. The 2.5-D models also indicate that South Park has the thinnest basin fill and is bounded on the east by the Elkhorn Thrust Fault. The Raton Basin is the easternmost of the Laramide age basins and new gravity and magnetic maps for it are being integrated with previous work done in the Park Basins. Spatial analysis of the various data will be used to clarify the structure and origin of these basins. Methods being employed include overlays of gravity contours over topography using a DEM. TM images will also be used in the construction of other overlays.

Associations between forest fragmentation patterns and geneticstructure in Pfrimer’s Parakeet (Pyrrhura pfrimeri), an endangered endemic to central Brazil’s dry forests  

USGS Publications Warehouse

When habitat becomes fragmented, populations of species may become increasingly isolated. In the absence of habitat corridors, genetic structure may develop and populations risk reductions in genetic diversity from increased genetic drift and inbreeding. Deforestation of the Cerrado biome of Brazil, particularly of the dry forests within the Parana˜ River Basin, has incrementally occurred since the 1970s and increased forest fragmentation within the region. We performed landscape genetic analyses of Pfrimer’s parakeet (Pyrrhura pfrimeri), a globally endangered endemic to the region, to determine if forest fragmentation patterns were associated with genetic structuring in this species. We used previously generated satellite imagery that identified the locations of Parana˜ River Basin forest fragments in 1977, 1993/94, and 2008. Behavioral data quantifying the affinity of Pfrimer’s parakeet for forest habitat was used to parameterize empirically derived landscape conductance surfaces. Though genetic structure was observed among Pfrimer’s parakeet populations, no association between genetic and geographic distance was detected. Likewise, least cost path lengths, circuit theorybased resistance distances, and a new measure of least cost path length complexity could not be conclusively associated with genetic structure patterns. Instead, a new quantity that encapsulated connection redundancy from the 1977 forest fragmentation data provided the clearest associations with pairwise genetic differentiation patterns (Jost’s D: r = 0.72, P = 0.006; FST: r = 0.741, P = 0.001). Our analyses suggest a 35-year or more lag between deforestation and its effect on genetic structure. Because 66 % of the Parana˜ River Basin has been deforested since 1977, we expect that genetic structure will increase substantially among Pfrimer’s Parakeet populations in the future, especially if fragmentation continues at its current pace.

Effects of cold fronts on MODIS-derived sensible and latent heat fluxes in Itumbiara reservoir (Central Brazil)  

NASA Astrophysics Data System (ADS)

In this work we investigate the cold front passage effects on sensible and latent heat flux in a tropical hydroelectric reservoir. The study area, Itumbiara reservoir (Goiás State/Brazil) at the beginning of the austral winter, is characterized by the presence of a weak thermal stratification and the passage of several cold fronts from higher latitudes of South America. Sensible and latent heat fluxes were estimated considering the atmospheric boundary layer stability. In situ and MODIS water surface temperature data were used to adjust the coefficients for momentum and heat exchanges between water and atmosphere and spatialize the sensible and latent heat fluxes. The results showed that during a cold front event the sensible heat flux can be up to five times greater than the flux observed before. The latent heat flux tends to decrease during the cold front but increase again after the passage. The highest values of heat loss were observed at littoral zone and some Reservoir's embayment. The heat loss intensification can be separated in two moments: first, during the cold front passage, when the wind speed increases and the air temperature decreases; second, after the cold front passage, with air humidity decreasing. This can be considered a key process to understanding the heat loss in the Itumbiara reservoir.

Sandflies (Diptera, Psychodidae) from forest areas in Botucatu municipality, central western S?o Paulo State, Brazil  

PubMed Central

Background The study of the distribution and ecology of sandfly species is essential for epidemiological surveillance and estimation of the transmission risk of Leishmania spp. infection. Findings In the present study, sandflies were captured in native fragmented forest areas in Rubião Júnior district, Botucatu municipality, São Paulo state, Brazil, between September 2001 and January 2005. A minimum of two automatic light traps were installed per night from 6 pm to 8 am, in different months, resulting in approximately 900 collecting hours. During this period, 216 sandfly specimens of sixteen species were captured. Pintomyia monticola and Brumptomyia guimaraesi were the most abundant with 56 specimens (25.93%) captured per species, followed by Pintomyia fischeri 28 (12.96%) and Psathyromyia pascalei 18 (8.33%). Other captured species were Lutzomyia amarali, Sciopemyia sordellii, Psathyromyia aragaoi, Nyssomyia whitmani, Migonemyia migonei, Pintomyia bianchigalatiae, Pintomyia misionensis, Brumptomyia carvalheiroi, Brumptomyia cardosoi, Brumptomyia cunhai, Brumptomyia nitzulescui, Brumptomyia brumpti and Brumptomyia spp. represented by 58 (26.85%) specimens. Conclusions Although less frequently found, the presence of Pintomyia fischeri, Nyssomyia whitmani and Migonemyia migonei, known vectors of Leishmania braziliensis, indicates risk of American cutaneous leishmaniasis occurrence. Moreover, the absence of Lutzomyia longipalpis-the main vector of Leishmania infantum chagasi, which is the agent of American visceral leishmaniasis-suggests that there is no risk of introduction and establishment of this disease in the studied area.

Environmental implications of jatropha biofuel from a silvi-pastoral production system in central-west Brazil.  

PubMed

We present a life cycle assessment of synthetic paraffinic kerosene produced from Jatropha curcas. The feedstock is grown in an intercropping arrangement with pasture grasses so that Jatropha is coproduced with cattle. Additional innovations are introduced including hybrid seeds, detoxification of jatropha seedcake, and cogeneration. Two fuel pathways are examined including a newly developed catalytic decarboxylation process. Sensitivities are examined including higher planting density at the expense of cattle production as well as 50% lower yields. Intercropping with pasture and detoxifying seedcake yield coproducts that are expected to relieve pressure on Brazil's forests and indirectly reduce environmental impacts of biofuel production. Other innovations also reduce impacts. Results of the baseline assessment indicate that innovations would reduce impacts relative to the fossil fuel reference scenario in most categories including 62-75% reduction in greenhouse gas emissions, 64-82% reduction in release of ozone depleting chemicals, 33-52% reduction in smog-forming pollutants, 6-25% reduction in acidification, and 60-72% reduction in use of nonrenewable energy. System expansion, which explicitly accounts for avoided deforestation, results in larger improvements. Results are robust across allocation methodologies, improve with higher planting density, and persist if yield is reduced by half. PMID:23713609

Molecular Detection and Characterization of Gastroenteritis Viruses Occurring Naturally in the Stream Waters of Manaus, Central Amaz?nia, Brazil?  

PubMed Central

To assess the presence of the four main viruses responsible for human acute gastroenteritis in a hydrographic network impacted by a disordered urbanization process, a 1-year study was performed involving water sample collection from streams in the hydrographic basin surrounding the city of Manaus, Amazonas, Brazil. Thirteen surface water sample collection sites, including different areas of human settlement characterized as urban, rural, and primary forest, located in the Tarumã-Açu, São Raimundo, Educandos, and Puraquequara microbasins, were defined with a global positioning system. At least one virus was detected in 59.6% (31/52) of the water samples analyzed, and rotavirus was the most frequent (44.2%), followed by human adenovirus (30.8%), human astrovirus (15.4%), and norovirus (5.8%). The viral contamination observed mainly in the urban streams reflected the presence of a local high-density population and indicated the gastroenteritis burden from pathogenic viruses in the water, principally due to recreational activities such as bathing. The presence of viral genomes in areas where fecal contamination was not demonstrated by bacterial indicators suggests prolonged virus persistence in aquatic environments and emphasizes the enteric virus group as the most reliable for environmental monitoring.

Fertility of Vriesea gigantea Gaud. (Bromeliaceae) in southern Brazil.  

PubMed

Plant fertility is a central subject of many questions in plant evolutionary and conservation biology. Pollen availability, abiotic resources, and flowering pattern can limit fruit and seed production. Open pollination and pollen supplementation studies are used to estimate any pollen limitation in natural populations. To study the impact of these factors on the reproductive success of Vriesea gigantea, an epiphytic bromeliad in the Atlantic Rainforest in Brazil, its fertility in four natural populations in Itapuã State Park was assessed by considering plant and inflorescence size, flower production, fruit and seed set, flower and fruit set pattern, and seed viability and germination rate. Supplemental pollination in adult plants was used to determine whether fruit production in V. gigantea is limited by reception of pollen. The results showed that V. gigantea has a high production of flowers, fruits, and seeds. Seeds are highly viable in all populations, presenting an average germination rate of 94% (SE ± 3.5). Plants of V. gigantea from Itapuã State Park are highly fertile. The high proportion of fruit and seed set after manual hand pollination indicates that the species is self-compatible. Pollination treatments showed evidence of pollinator limitation in the Itapuã State Park population. PMID:21636436

Effect of public opinion on national park planning in Turkey: A case study  

NASA Astrophysics Data System (ADS)

National park plans are mainly prepared by a central planning team of the National Parks of Turkey. In this article, a model is presented that proposes a different approach to preparing national park plans. The study is based on a questionnaire distributed among the residents of the villages just outside a selected national park in Turkey and the relevant local and general authorities who are interested in the national park in their region, to find out the effect of public opinion on national park planning. Four basic strategies that represent the four main alternative approaches to forming policies in the planning of the park were identified. Respondents were asked to choose one and to suggest their own ideas. As this is a first attempt of such a study in Turkey, the results of the survey have been very encouraging. Therefore, this paper suggests that the assessment of public opinion should be borne in mind throughout the planning process in Turkey.

Physical activity, park access, and park use among California adolescents.

In California, 2.15 million adolescents (62.9%) do not engage in at least 60 minutes of physical activity five or more days per week. Adolescents who visited a park in the past month and those who live in a park service area are more likely to meet this goal. Lower-income California adolescents are less likely to visit local parks and more likely to believe local parks are unsafe. Actions by state and local policymakers to increase park access and attractiveness, especially to underserved populations, may be an effective way to promote physical activity among California's adolescents.

Diet, reproduction and population structure of the introduced Amazonian fish Cichla piquiti (Perciformes: Cichlidae) in the Cachoeira Dourada reservoir (Paranaíba River, central Brazil).  

PubMed

The Blue Peacock Bass (Cichla piquiti), native to the Tocantins-Araguaia river basin of the Amazon system, was introduced into the basin of the Paranaíba River, Paraná River system. Cachoeira Dourada reservoir is one of a series of dams on the Paranaíba River in central Brazil, where this fish has become established. A study of its feeding spectrum, combined with information about its reproductive characteristics and population structure, would enable the current state of this species in the reservoir to be assessed and might provide useful data for the management of other species native to this habitat. This study showed that the peacock bass has no predators or natural competitors in the reservoir and that reproduces continuously, with high reproductive rates, and has a smaller median length at first maturity (L50) than other species of Cichla. Its successful establishment in habitats strongly affected by human activity should cause changes in the whole structure of the local fish communities. Nonetheless, in this reservoir, there appears to be some sharing of the functions of this species with native carnivorous fish, a situation that may be sustained by the presence of a wide variety of foraging fish.

PubMed

The objective of this study was to evaluate potential avian dispersers of Miconia theaezans by dietary habits in the Cerrado of Central Brazil. Forty-two hours and 40 minutes of focal tree observation were conducted between 7:00 AM and 5:00 PM. For each bird species that consumed the fruit, we registered: the time they remained on the plant, the total amount of fruit they consumed, foraging tactics and strategies to consume the fruit. Five-hundred and fifty-nine units of fruit were consumed in 47 visits by seven bird species. Thraupidae was the most frequent and representative family and Tangara cayana was the main consumer. The Tachyphonus rufus had the highest rate of intake of the entire fruit, however the rates were not significantly different among the visitors. The most-used foraging tactic by all species was to consume the fruit while "perched" (95.74% of the visits). The most commonly-used consumption strategy was to mandibulate the fruit and swallow all the contents (65.12%). Omnivores were the predominant visitors (71.43%) and made most of the visits (89.36%). All visiting species could act as potential dispersers of M. theaezans, which demonstrates the low selectiveness of this pioneer plant towards its frugivorous. PMID:22437381

Preliminary investigation of the central nervous system effects of 'Tira-capeta' (Removing the Devil), a cigarette used by some Quilombolas living in Pantanal Wetlands of Brazil.  

PubMed

During an ethnopharmacological survey carried out among some Quilombolas living in Brazil, 48 plants with possible central nervous system (CNS) action were cited. A mixture of nine plants, known as 'Tira-capeta' (Removing the Devil) cigarette, has been utilized for years as a tonic for the brain. The effects observed after consuming this cigarette are: dizziness, lightness sensation, humor changes, yawns, heavy eyes, hunger, sleep and relaxation. This study aimed to verify the effects of a hydroalcohol extract of 'Tira-capeta' cigarette (ETC), as well as to evaluate the phytochemical profile. The phytochemical screening carried out through characterization reactions, thin layer chromatography and high efficiency liquid chromatography indicated the presence of tannins, phenolic acids, flavonoids, saponins and alkaloids; tannins and phenolic acids being the principal constituents. The pharmacological tests showed that ETC induced a biphasic effect, with intense initial stimulation of the CNS, followed by a general depressor state; decreased the latency for sleeping and increased the total sleeping time (50, 100 and 500 mg/kg), without causing prejudice in motor coordination (doses up to 200 mg/kg); induced catalepsy in mice, verified 10 and 50 min after drug administration (500 mg/kg). Also, no anxiolytic or anxiogenic effects were verified in rats submitted to the elevated plus-maze. PMID:18570235

Yellowstone National Park  

NSDL National Science Digital Library

Yellowstone National Park was established on March 1, 1872, as the first national park in the world. The overwhelming and unique beauty found in this natural wonder is truly difficult to describe.This Topic In Depth begin with the excellent National Park Service's (1) official Yellowstone Web Site, which contains the park's history, virtual field trips, park information, visitor guides, web cams, kids pages, and more. The next site offered by EarthTalk Studios is called Yellowstone Geographic. This extensive and graphically reliant site contains superb interactive activities related to the park and comes close to its goal of being "the best Yellowstone Web Site on the planet." The third site from UnMuseum.org called Weird Geology: Geysers explores the workings of Yellowstone's famous geysers with descriptions, photographs, illustrations, and a movie of an eruption. The next site from Exploratorium is a learning activity called Geyser: Cyclic Hot Water Fountain. With the help of their teacher, students build a working model of a geyser from common chemical equipment. From the University of Michigan, Meg Streepey's Geysers and the Earth's Plumbing Systems Web Site describes (for more advanced students) how geysers work, including how to analyze their thermal and hydrologic regimes. Another research site, from the University of Utah's College of Mines and Earth Sciences, is the GPS Surveys of the Yellowstone Hotspot and the Wasatch Fault, Utah. Objectives of the study are "to measure and understand the spatial and temporal variations of the crustal deformation produced by the interaction between lithospheric plate motion and the asthenospheric hotspot." The last two sites are from the USGS, the first of which is the Yellowstone River Basin National Water-Quality Assessment Program site. It contains a project description, available data, and other relevant information. The last site, Yellowstone Volcano Observatory, is a facility that is designed for observing volcanic and earthquake activity in the park. This site also contains a project description, volcanic data, maps, descriptions of volcanic rock, a frequently asked questions link, and more.

Geology, petrology and geochemistry of the "Americano do Brasil" layered intrusion, central Brazil, and its Ni-Cu sulfide deposits  

NASA Astrophysics Data System (ADS)

The "Americano do Brasil" Complex (ABC) is part of a cluster of coeval synorogenic mafic-ultramafic intrusions emplaced during the Brasiliano/Pan-African Orogenic Cycle in Brazil. The medium-sized ABC consists of interlayered dunite, peridotite, websterite, and gabbronorite. High Fo values of olivine (up to Fo88) and the crystallization sequence of the ABC (Ol + Chr ? Ol + Opx + Chr ? Cpx + Opx ? Opx + Pl + Cpx ? Opx + Pl + Cpx + Ilm + Mag) suggest crystallization from tholeiitic high-MgO parental magmas. Light rare earth element (REE)-enriched mantle-normalized REE profiles and ?Nd(T) values of +2.4 for cumulate rocks from the ABC suggest a depleted mantle source for the parental magma. The ABC Ni-Cu sulfide deposit (3.1 Mt at 1.12 wt.% Ni and 1.02 wt.% Cu) consists of three distinctively different orebodies (S1, S2, and G2). The S2 orebody, an unusual occurrence of stratiform massive sulfide hosted by dunite and peridotite in the interior of a layered intrusion, results from sulfides accumulated at the transient base of the magma chamber following a new influx of parental magma. The G2 orebody has an irregular and roughly cylindrical shape, consisting mainly of net-textured sulfides. The G2 orebody is hosted by peridotite and pyroxenite and located stratigraphically below the S1 orebody. S2 and G2 orebodies are characterized by low Cu/Cu + Ni ratios (mainly below 0.4). The S1 orebody, hosted by websterite and gabbronorite in the more fractionated sequence of the ABC, is a cluster of several irregular discontinuous orebodies of Ni-Cu disseminated sulfides. The sulfides of the S1 orebody have high Cu/Cu + Ni ratios (mainly between 0.5 and 0.8) and are highly depleted in PGE. The S1 orebody is interpreted to result from a later event of sulfide segregation in the magma chamber, possibly following the event that originated the G2 orebody. The bulk of ?34S values for sulfides of the ABC orebodies and their host rocks fall in the range of 0 ± 2‰. Higher ?34S values (between 3‰ and 5‰) are restricted to pyrite from xenoliths of gneiss located close to the S1 orebody and sulfides from the S1 orebody. Crustal xenoliths and chemical data (lithogeochemistry and sulfur isotope composition) provide evidence of crustal contamination of the igneous rocks hosting the S1 orebody, suggesting that sulfur saturation was induced by contamination with sulfide-bearing crustal rocks. The ABC deposit is an example of Ni-Cu sulfide mineralization hosted by synorogenic mafic-ultramafic intrusions. The S2 orebody is the first documented example of an economic stratiform massive sulfide orebody located within layered intrusions, expanding the opportunities for exploration of Ni-Cu sulfides in orogenic regions worldwide.

The hydrothermal system in the vicinity of Lassen Volcanic National Park contains a central region of fluid upflow in which steam and liquid phases separate, with steam rising through a parasitic vapor-dominated zone and liquid flowing laterally toward areas of hot spring discharge south of the Park. A simplified numerical model was used to simulate the 10,000-20,000 year evolution of this system and to show that under certain circumstances fluid withdrawal from hot-water reservoirs south of the Park could significantly alter the discharge of steam from thermal areas within the Park.

Parks and wilderness are a unique experiment in public ownership and management with no significant counterparts in our national experience. Despite occasional controversy, the propriety of large-scale federal land ownership and management was a settled issue long before the era of big national government or federal regulation began. This gave rise to a paradox with greater continuity in federal policy and public perception of land policy on one hand and the dislocating of old, established federal land management bureaucracies on the other. The author shows in the history of the wilderness movement that the American system is capable of producing real change; that reform is possible even if the methods are unexpected. Sharing the power among the administration, courts, and legislature opens the process to a range of interest groups with different opportunities for access. As values change, the system makes transitions manageable.

Geochemistry of Jamari complex, central-eastern Rondônia: Andean-type magmatic arc and Paleoproterozoic crustal growth of the southwestern Amazonian Craton, Brazil  

NASA Astrophysics Data System (ADS)

The Jamari complex (gabbro-diorite-tonalite/enderbite-granodiorite/charnoenderbite) represents a Paleoproterozoic (ca. 1.76-1.74 Ga) magmatic arc emplaced along the southwestern Amazonian Craton in central-eastern Rondônia, Brazil. Comprising metaplutonic and metasedimentary rocks, the Jamari complex constitutes the polydeformed Paleoproterozoic basement of Rondônia state. Together with regional data from the Rondônia-Juruena Province, our findings suggest that the southwestern border of the Amazonian Craton was the site of magmatic arc evolution from at least ca. 1.78 to 1.63 Ga. Elemental geochemical data show that intermediate/acid orthogneisses are metaluminous to mildly peraluminous, and have a medium to high-K, calc-alkaline signature, suggesting that they were formed in an immature Andean-type magmatic arc. Gabbros have signatures similar to tholeiites of active continental margin and diorites show characteristics compatible with rocks of tholeiite/calc-alkaline active continental margin volcanic arc. The chemical data of the Jamari complex felsic plutonic rocks show general trends of increasing contents of incompatible elements (K2O, Rb, Nb, Th, La, Ba and Sr) and decreasing contents of compatible elements (Ni, V, Sc, MgO, Fe2O3, Al2O3, CaO and TiO2) with increasing SiO2. Although these variations are consistent with closed system fractional crystallization processes, the wide variation of Rb/Zr, La/Sm, K/Rb, Nb/Y, Th/Y and Th/Yb in the felsic rocks may indicate random crustal contamination during the evolution of these rocks. Normalized trace element patterns show enrichment in LILEs (Rb, Ba, K, Th and Ce) relative to HFSEs (Nb, Zr, P and Ti) and are very similar to calc-alkaline subduction-related rocks from orogenic belts. The Jamari complex represents the western extension of similar metaplutonic rocks (Juruena Complex, Mato Grosso), occurring along some 500 km of the Paleoproterozoic Madeirinha orogen (1.78-1.63 Ga). During this event the rocks were metamorphosed under upper amphibolite to granulite facies conditions that only mildly disturbed their igneous characteristics. Zircon U-Pb crystallization ages (ID-TIMS, SHRIMP and LA-ICP-MS) set the acretional phase of the magmatic arc in Rondônia between 1.76 and 1.74 Ga. Metamorphic mineral paragenesis and textural features in these rocks, combined with geochronologic data, indicate that metamorphic conditions in the study area reached the granulite facies (T = ca. 750-800 °C, P = 7 to 8 kbar) in a tectonothermal collisional event that occurred between 1.67 and 1.63 Ga. The Jamari complex in this region was subsequently reworked during the Rondonian-San Ignácio Orogeny (1.50-1.30 Ga), a tectonic episode characterized by crytical metamorphic mineral assemblages and anatexis, suggesting upper-amphibolite-facies metamorphism. The youngest tectonic event recognized in the Jamari complex is associated with tectonic reactivation, deformation, thermal overprint, and magmatism related to the Sunsás Orogeny (1.30-0.95 Ga). Its effects are represented by extensive development of shear zones (Ji-Paraná system), mylonitic belts, rifts and sedimentary deposits, and post-collisional A-type intrusions. Nd isotopic data of the high-grade orthogneisses show a wide range of ?Nd values (-1.5 to +5.6) and a wide spectrum of TDM model-ages, from 1.79 to 2.2 Ga. These values demonstrate that the crustal generation processes involved juvenile mantle sources and variable proportions of older recycled crust.

Views of the National Parks  

NSDL National Science Digital Library

There is no true substitute for visiting one of America's great national parks, but this website, designed "to present the natural, cultural, and historical resources of our national parks," is a nice surrogate for an in-person jaunt. On the homepage, visitors can select a park or theme from several dozen headings, including National Mall, Whiskeytown, Glaciers, and Devils Tower. Within each area, visitors can examine a series of high-quality images, along with four or five sections that address different aspects of each topic or specific park. Perhaps the most useful elements of the site are the very fine resources for teachers. Clicking on the Teachers' Lounge area will bring up a number of high-quality educational articles, lesson plans, and educational standards guidelines. All told, there are 14 different lesson plans here, which are complemented by links to external resources and additional readings. [KMG

Suicide and the parking garage.  

PubMed

Each year over one million Americans attempt suicide, and over 30,000 succeed. One of the most popular and successful, methods of suicide is jumping, the authors point out, and one of the most widely-used venues for jumping are parking garages. Especially vulnerable to such suicide attempts are the parking structures of hospitals, they report, because it has been found that most persons who jump to their death had been previously treated for a mental health condition. (One hospital in Massachusetts recently reported that a man jumped or fell from the second floor of one of its parking decks, the second such incident at one of its garages in five years.) In this article the authors discuss how parking professionals can help prevent suicide from happening and how to handle this situation if it does occur in your garage. PMID:21916292

Lichens of the U. S. national parks  

USGS Publications Warehouse

Over 26,100 records of lichens present in 144 U.S. national park units were assembled from various sources into a database and analyzed. Within these 144 park units 2,435 species and 375 genera are reported, representing 63% and 74% of the North American flora, respectively. The park units are located in 41 states and Washington, D.C. The average number of species in a park is 104, but the median is 60, indicating there are many parks with a small number of species and a few with high numbers. Isle Royale National Park has the most species, 611, and twelve parks have only one species reported. The number of records of lichens present ranged from one for 25 parks, to 1,623 for Isle Royale. Physcia aipolia is the most frequently observed species, being found in 65 parks. One fourth of the park units are classified cultural resource parks, while the remainder are considered natural resource parks. This study was based on 453 sources, including literature citations, park reports and collections in the University of Minnesota Herbarium.

Eco-hydrologic role of urban parks in Queretaro City  

NASA Astrophysics Data System (ADS)

Urban parks are essential for the well-being and comfort of urban zones, vegetation plays an important role in the water balance, but these areas rarely are considered as urban infrastructure, this is why studies are necessary to assess the eco-hydrological role of urban parks and the micro climate effect of them in adjacent areas. The study is carried out during the raining seasons of 2010 and 2011 in six urban parks located in the central area of the Queretaro valley: Alameda Centro, Alamos, Alcanfores Norte, Arboledas, Cerro de las campanas and Queretaro 2000. This work aims to measure and modeling the rainfall interception process from measuring some random plots into the urban parks, also to evaluate the water balance and the runoff that is spilled to the drainage system. According to previous studies it is expected that vegetation intercepts more than 60% of total rainfall so the runoff in urban areas decrease, also to quantify the available water volume to infiltrate to aquifer recharge.

The Geologic Story of Canyonlands National Park  

USGS Publications Warehouse

On September 12, 1964, President Lyndon B. Johnson signed an act of Congress establishing Canyonlands as our thirty second national park, the first addition to the park system since 1956. The birth of Canyonlands National Park was not without labor pains. In the 1930's virtually all the vast canyon country between Moab, Utah, and Grand Canyon, Ariz., was studied for a projected Escalante National Park. But Escalante failed to get off the ground, even when a second attempt was made in the 1950's. Not until another proposal had been made and legislative compromises had been worked out did the park materialize, this time under a new name - Canyonlands. Among the many dignitaries who witnessed the signature on September 12 was one of the men most responsible for the park's creation, park superintendent Bates E. Wilson, who did the pioneer spade work in the field.

Seattle Parks & Recreation Sherwood History Files  

NSDL National Science Digital Library

The Seattle Parks & Recreation Sherwood History Files are the work of one Donald N. Sherwood, who worked as an engineer for the department for 22 years. In the course of his work, he began compiling sketch maps of the parks, and annotating them with historical tidbits and other pieces of information. Also, he began writing individual histories for each facility when the information didn't quite fit on the maps. This site afford interested parties access to these remarkable and truly unusual documents. All told, there are over 80 separate files here, documenting unique pieces of the Seattle parks landscape, including Alki Beach Park, Golden Gardens Park, and the celebrated Gas Works Park on Lake Union. For anyone with an interest in parks and recreation management or the Emerald City, this site will be a most welcome find.

The vascular plant flora of Hopewell Culture National Historical Park. Ross County, Ohio  

USGS Publications Warehouse

HopewellCulture National Historical Park, a unit of the United States National Park Service located in Ross County in south central Ohio, was created to restore, protect, and interpret the legacy of the mound building Hopewell prehistoric peoples. The vascular flora of the park had been estimated to be only 20% known prior to the undertaking of this project. During the spring, summer, and fall of 1995, almost 700 plant specimens were collected by three investigators from five units of the park. Totals of 438 species, 281 genera, and 93 families of vascular plants were discovered, representing 40% of the flora of Ross County, and 17% of the flora of Ohio. Introduced species constituted 32% of the flora. Sixty-five species are new records for Ross County. Two species of special concern, Spiranthes ovalis and Eleocharis ovata, are on the state's threatened and endangered species list. The Hopewell unit had the highest plant diversity of the five units.

Air pollution vulnerabiity of 22 midwestern parks  

SciTech Connect

Air pollution increases in United States national parks as sources grow closer. As this happens, biota will be increasingly affected. Can it be determined in advance which parks will be more impacted by these air pollutants that others? This study of 22 park units in the midwestern United States attempted to answer this question. Plant lists were compiled for the 22 parks, relative abundances of all species (common, intermediate, rare) estimated, their sensitivities from their life cycle types (annual, perennial-deciduous, perennial-evergreen) determined, and overall vulnerability as the average product of the two was calculated using a 3-2-1 scale for weighting the abundances. Scotts Bluff National Monument in western Nebraska was the most vulnerable park in the region, while Isle Royale National Park in Lake Superior was the least. This difference was due to the higher abundances of annual plant species in Scotts Bluff. Changing the values used for abundances changed the order of park vulnerabilites. Three air pollutants (ozone, sulfur dioxide, and sulfate) were found to increase from west to east in the midwest. Overlaying these patterns on the park vulnerabilities, and a customer analysis of the data, resulted in a determination of the air pollution risks to groups of parks. The parks most at risk (high vulnerability+high pollution levels) were two in Ohio (Hopewell Culture National Historical Park and Cuyahoga Valley National Recreation Area) and one in Indiana (Lincoln Boyhood National Memorial). Ten parks were grouped at lowest risk in an arc from Lake Superior, northern Minnesota, and Wisconsin through Nebraska and Kansas. Of three different surrogate methods tested for a relationship with overall vulnerability, only one appeared to be useful. Vulnerability could be directly calculated if a park`s vegetative structure was known without assembling the complete flora. 22 refs., 7 figs., 9 tabs.

Atmospheric mercury speciation in Yellowstone National Park  

USGS Publications Warehouse

Atmospheric concentrations of elemental mercury (Hg0), reactive gaseous Hg (RGM), and particulate Hg (pHg) concentrations were measured in Yellowstone National Park (YNP), U.S.A. using high resolution, real time atmospheric mercury analyzers (Tekran 2537A, 1130, and 1135). A survey of Hg0 concentrations at various locations within YNP showed that concentrations generally reflect global background concentrations of 1.5-2.0 ng m- 3, but a few specific locations associated with concentrated geothermal activity showed distinctly elevated Hg0 concentrations (about 9.0 ng m- 3). At the site of intensive study located centrally in YNP (Canyon Village), Hg0 concentrations did not exceed 2.5 ng m- 3; concentrations of RGM were generally below detection limits of 0.88 pg m- 3 and never exceeded 5 pg m- 3. Concentrations of pHg ranged from below detection limits to close to 30 pg m-3. RGM and pHg concentrations were not correlated with any criteria gases (SO2, NOx, O3); however pHg was weakly correlated with the concentration of atmospheric particles. We investigated three likely sources of Hg at the intensive monitoring site: numerous geothermal features scattered throughout YNP, re-suspended soils, and wildfires near or in YNP. We examined relationships between the chemical properties of aerosols (as measured using real time, single particle mass spectrometry; aerosol time-of-flight mass spectrometer; ATOFMS) and concentrations of atmospheric pHg. Based on the presence of particles with distinct chemical signatures of the wildfires, and the absence of signatures associated with the other sources, we concluded that wildfires in the park were the main source of aerosols and associated pHg to our sampling site. ?? 2005 Elsevier B.V.

The Glória quartz-monzodiorite: isotopic and chemical evidence of arc-related magmatism in the central part of the Paleoproterozoic Mineiro belt, Minas Gerais State, Brazil.  

PubMed

The Glória quartz-monzodiorite, one of the mafic plutons of the Paleoproterozoic Mineiro belt, is intrusive into banded gneisses, amphibolites, schists and phyllites of the Rio das Mortes greenstone belt, in the southern portion of the São Francisco Craton, State of Minas Gerais, Brazil. The Glória quartz-monzodiorite yields a SHRIMP U-Pb zircon age of 2188 +/- 29 Ma, suggesting a tectonic relationship with the pre-collisional phase of the Mineiro belt. According to the Nd isotopic evidence (epsilonNd(T) = -3.4; T DM = 2.68 Ga) the original magmas was formed by a mixture among Archean crustal material and Paleoproterozoic juvenile magma. The Glória quartz-monzodiorite shows metaluminous and calc-alkaline tendency with intermediate K content, comparable to that of volcanic-arc rocks. The primary mineralogical assemblage was partly modified by metamorphism, dated between 2131-2121 Ma in nearby coeval plutons. Such metamorphism is significantly older than the reported metamorphic episodes of the Mineiro belt in the Quadrilátero Ferrífero region (2059-2041 Ma) in the eastern portion of the study area. This evidence, together with chemical and isotopic data from other mafic and felsic plutons coeval with the Glória quartz-monzodiorite, indicate a tectonic and magmatic migration within the Mineiro belt from west to east.

The Bronx Park Postcard Collection  

NSDL National Science Digital Library

Over the years since its origins in the late 1880s, the Bronx Park has been expanded several times. In 1891, the city of New York allotted 250 acres of the park to the New York Botanical Garden, and in 1897 assigned 250 more to the Bronx Zoo. This particular digital collection brings together postcards of the grounds held by the Wildlife Conservation Society Library and the Garden's LuEsther T. Mertz Library. The collection here includes over 450 postcards, which visitors can browse by subject headings, including Zoo animals, Paths and walkways, and Bronx River. The Zoo animals area is well worth a look, as it features a range of animals, including a Noah's Ark exhibit, camels, and Indian elephants. It's an amazing archive of documents related to one of the most famous zoos in the United States, and historians and others will find it quite marvelous.

Coordinating OBS Parks in Europe  

NASA Astrophysics Data System (ADS)

Within Europe there are more than 380 Ocean Bottom Seismometers (OBS) distributed across 10 instrument parks in 6 countries. At least 120 of these OBS are wideband or broadband, over 260 can be deployed for at least 6 months at a time and 140 for at least one year. New parks are planned in two other European countries, which should add over 70 OBSs to this "fleet". However, these parks are under the control of individual countries or universities and hence to date this has made it difficult to organize large-scale experiments, especially for seismologists without marine experience. There has recently been an initiative to coordinate the use of these distributed instruments and their data products, to encourage large-scale experiments, possibly with onshore and offshore components, by seismologists who have not necessarily used OBSs before. The ongoing or planned developments include: Helping scientists with marine-specific formalities such as ship requests; clearer explanations of the noise floors of OBS instrumentation; improved clarity of instrument pricing and availability; standardized data output formats and data validation; and archiving in established seismological data centers. These efforts should allow improved experiment design in scientifically interesting regions with an offshore component and an easier, clearer way to organize large-scale, multi-country experiments. We will present details of this initiative to help organize large-scale experiments, the particularities of OBS sensors and marine deployments, the available instrumentation and new developments.

[An epidemiological profile of dental caries in 12-year-old children residing in cities with and without fluoridated water supply in the central western area of the State of São Paulo, Brazil].  

PubMed

This study aimed to analyze the epidemiological profile of dental caries in the central western region of the State of São Paulo, Brazil, focusing on 12-year-old children by gender, comparing the DMFT index in fluoridated and non-fluoridated cities. The study used data from the Epidemiological Surveys in the State of São Paulo, 1998, pertaining to the 10th Regional Health Directorate, including 8 cities. The sample consisted of 485 schoolchildren, both boys and girls, distributed by city. In Pederneiras (a medium-sized city with a fluoridated water supply), DMFT was 7.06, higher than the Brazilian national mean for 1986. Boys showed a higher prevalence of dental caries than girls, showing a new trend for dental caries in the region. There was no statistically significant difference between DMFT in municipalities of the same size, regardless of the presence or absence of fluoride in the water supply, thus suggesting a "convergence" phenomenon, possibly due to the intake of other sources of fluoride and the presence of a "halo" effect. Prevalence of caries in the region was "high", with a DMFT of 4.82, thus failing to reach the goals set for the year 2000. PMID:12244360

Neighborhood poverty, park use, and park-based physical activity in a Southern California city.  

PubMed

A rich literature indicates that individuals of lower socio-economic status engage in less leisure time physical activity than individuals of higher socio-economic status. However, the source of the difference is believed to be, in part, due to differential access to resources that support physical activity. However, it has not been shown as to whether equal access to parks can mitigate differences in leisure time physical activity. Using systematic direct observation, we quantified physical activity in neighborhood parks in a large Southern California city located in areas with high, medium, and a low percentage of households in poverty. We documented how neighborhood parks are managed and programmed and also interviewed both a sample of park users and a random sample of households within a mile radius of the parks. We found that parks are used less in high-poverty areas compared to medium- and low-poverty area parks, even after accounting for differences in size, staffing, and programming. The strongest correlates of park use were the number of part time staff, the number of supervised and organized programs, and knowing the park staff. Perceptions of safety were not relevant to park use among those interviewed in the park, however it had a small relationship with reported frequency of park use among local residents. Among park users, time spent watching electronic media was negatively correlated with the frequency of visiting the park. Future research should test whether increasing park staffing and programming will lead to increased park use in high-poverty neighborhoods. PMID:23010338

Geologic Map of the Shenandoah National Park Region, Virginia  

USGS Publications Warehouse

The geology of the Shenandoah National Park region of Virginia was studied from 1995 to 2008. The focus of the study was the park and surrounding areas to provide the National Park Service with modern geologic data for resource management. Additional geologic data of the adjacent areas are included to provide regional context. The geologic map can be used to support activities such as ecosystem delineation, land-use planning, soil mapping, groundwater availability and quality studies, aggregate resources assessment, and engineering and environmental studies. The study area is centered on the Shenandoah National Park, which is mostly situated in the western part of the Blue Ridge province. The map covers the central section and western limb of the Blue Ridge-South Mountain anticlinorium. The Skyline Drive and Appalachian National Scenic Trail straddle the drainage divide of the Blue Ridge highlands. Water drains northwestward to the South Fork of the Shenandoah River and southeastward to the James and Rappahannock Rivers. East of the park, the Blue Ridge is an area of low relief similar to the physiography of the Piedmont province. The Great Valley section of the Valley and Ridge province is west of Blue Ridge and consists of Page Valley and Massanutten Mountain. The distribution and types of surficial deposits and landforms closely correspond to the different physiographic provinces and their respective bedrock. The Shenandoah National Park is underlain by three general groups of rock units: (1) Mesoproterozoic granitic gneisses and granitoids, (2) Neoproterozoic metasedimentary rocks of the Swift Run Formation and metabasalt of the Catoctin Formation, and (3) siliciclastic rocks of the Lower Cambrian Chilhowee Group. The gneisses and granitoids mostly underlie the lowlands east of Blue Ridge but also rugged peaks like Old Rag Mountain (996 meter). Metabasalt underlies much of the highlands, like Stony Man (1,200 meters). The siliciclastic rocks underlie linear ridges from 800 to 400 meters in altitude. The Page Valley is underlain by Cambrian and Ordovician carbonate rocks. Siliciclastic rocks are mostly west of the South Fork of the Shenandoah River and underlie Massanutten Mountain. Surficial deposits in the highlands include colluvium and debris fans. The lowlands have broad alluvial fans, alluvial plains, and fluvial terraces. Ridges underlain by siliciclastic rocks have abundant boulder fields. Numerous sinkholes and caves are due to the dissolution of the carbonate bedrock.

In search of traditional bio-ecological knowledge useful for fisheries co-management: the case of jaraquis Semaprochilodus spp. (Characiformes, Prochilodontidae) in Central Amazon, Brazil.  

PubMed

The jaraquis (Semaprochilodus spp.) are the most abundant group in the fishing landing in Manaus. However, just command and control management strategies have been used by the fishery governmental agency in the region without the power to enforce centralized decisions. The fishermen and their culture represent a source of information on dynamics of the resources and aquatic environments, fundamental in making possible the co-management of the fishing resources. The present study aims to contribute to management through identification of common information available in scientific and traditional knowledge about the jaraquis' bio-ecology. There were 57 semi-structured interviews recorded with fishermen of Manaus and rural areas of Manacapuru in 2002 concerning biological and ecological aspects. Similarity was observed between scientific and traditional knowledge in the following items: size of first sexual maturation, spawning type, parental care, trophic relationships and migratory behavior, as well as in some aspects of the mortality and growth of the species. However, there was less ethnoicthyological information on fecundity and the determination of the age and growth of adult fish. Common information would be used preferably by agencies to start an effective and technical dialogue with commercial and riverine fishermen to design management plans in a decentralized strategy.

Mollusks of Manuel Antonio National Park, Pacific Costa Rica.  

PubMed

The mollusks in Manuel Antonio National Park on the central section of the Pacific coast of Costa Rica were studied along thirty-six transects done perpendicular to the shore, and by random sampling of subtidal environments, beaches and mangrove forest. Seventy-four species of mollusks belonging to three classes and 40 families were found: 63 gastropods, 9 bivalves and 2 chitons, during this study in 1995. Of these, 16 species were found only as empty shells (11) or inhabited by hermit crabs (5). Forty-eight species were found at only one locality. Half the species were found at one site, Puerto Escondido. The most diverse habitat was the low rocky intertidal zone. Nodilittorina modesta was present in 34 transects and Nerita scabricosta in 30. Nodilittorina aspera had the highest density of mollusks in the transects. Only four transects did not clustered into the four main groups. The species composition of one cluster of transects is associated with a boulder substrate, while another cluster of transects associates with site. Two clusters were not associated to any of the factors recorded. Some species were present in previous studies but absent in 1995, while others were absent in the previous studies but found in 1995. For example, Siphonaria gigas was present in 1995 in many transects with a relatively high density, but absent in 1962, probably due to human predation before the establishment of the park. Including this study, a total of 97 species of mollusks in three classes and 45 families have been reported from Manuel Antonio National Park. Sixty-nine species are new reports for the area: 53 gastropods, 14 bivalves and 2 chitons. There are probably more species of mollusks at Manuel Antonio National Park, than the 97 reported here, because some areas have not been adequately sampled (e.g., deep environments) and many micro-mollusks could not be identified.

Initial analysis from a lidar observation campaign of sugar cane fires in the central and western portion of the São Paulo State, Brazil  

NASA Astrophysics Data System (ADS)

The central and western portion of the Sao Paulo State has large areas of sugar cane plantations, and due to the growing demand for biofuels, the production is increasing every year. During the harvest period some plantation areas are burnt a few hours before the manual cutting, causing significant quantities of biomass burning aerosol to be injected into the atmosphere. During August 2010, a field campaign has been carried out in Ourinhos, situated in the south-western region of Sao Paulo State. A 2-channel Raman Lidar system and two meteorological S-Band Doppler Radars are used to indentify and quantify the biomass burning plumes. In addiction, CALIPSO Satellite observations were used to compare the aerosol optical properties detected in that region with those retrieved by Raman Lidar system. Although the campaign yielded 30 days of measurements, this paper will be focusing only one case study, when aerosols released from nearby sugar cane fires were detected by the Lidar system during a CALIPSO overpass. The meteorological radar, installed in Bauru, approximately 110 km northeast from the experimental site, had recorded "echoes" (dense smoke comprising aerosols) from several fires occurring close to the Raman Lidar system, which also detected an intense load of aerosol in the atmosphere. HYSPLIT model forward trajectories presented a strong indication that both instruments have measured the same air masss parcels, corroborated with the Lidar Ratio values from the 532 nm elastic and 607 nm Raman N2 channel analyses and data retrieved from CALIPSO have indicated the predominance of aerosol from biomass burning sources.

Elk Monitoring Protocol for Lewis and Clark National Historical Park, Version 1.0  

USGS Publications Warehouse

Maintaining elk (Cervus elaphus roosevelti) herds that frequent Lewis and Clark National Historical Park (NHP) is central to the park’s purpose of preserving the historic, cultural, scenic, and natural resources. Elk were critical to sustaining the members of the Lewis and Clark expedition by providing food and clothing over the winter of 1805-1806. Today, elk viewing opportunities in the park and surrounding region generate broad appeal with the visiting public, which number over 250,000 per year at the Fort Clatsop visitor center. This protocol describes procedures for monitoring trends in the use of the Fort Clatsop area by Roosevelt elk. Specific objectives of elk monitoring in Lewis and Clark NHP are to measure the relative use and proportion of area used by elk during winter in the Fort Clatsop Unit of the park, and the rate at which elk are sighted from roads in and around the park. Relative use and the proportion of area used by elk are determined from elk fecal pellet surveys conducted every other year in the Fort Clatsop park unit. Pairs of observers visit a systematic array of permanent plots in the fall to clear them of elk fecal pellets, and return to the plots in late winter to count elk fecal pellets that have accumulated during winter. Half of the subplots are counted by two independent observers, which allows for the estimation of relative use and proportion of area occupied by elk with analyses of detection biases that account for unseen elk pellet groups. Standardized road surveys are conducted in and near the Fort Clatsop park unit three or four times monthly during alternate months. Data from road surveys are used to quantify the rate that park visitors would be expected to see elk, when driving the selected set of routes. The monitoring protocol is based on three field seasons of development and testing. The protocol narrative describes the background, rationale, sampling design, field methods, analytical methods, data management, reporting, personnel requirements, and operational requirements for elk monitoring in Lewis and Clark NHP. The sampling design reflects tradeoffs between statistical and ecological considerations, safety, and current budget considerations. The protocol provides adequate power to detect a doubling or halving of elk use in the Fort Clatsop unit and surrounding areas within 15 years. Step-by-step guidance for planning and completing the monitoring tasks are in the attached standard operating procedures (SOPs). Information on the status and trends of elk use in Lewis and Clark NHP will allow park managers to assess the effects on elk of restoration programs within the park, build community partnerships, and identify potential linkages between regional land use changes and elk use of the Park. Lewis and Clark NHP has an active ecological restoration program that aims to recreate, where possible, ecological conditions that Lewis and Clark encountered. The restoration program includes an extensive exotic plant removal program, wetland restoration, and silvicultural treatments that will hasten development of late-seral conditions in recently acquired forest lands of the Fort Clatsop park unit. In the future, monitoring results can be used to test for spatial associations between ecological restoration treatments and relative use by elk. The park also plans to feature results from elk monitoring prominently in its educational outreach activities to help interpret the historical and current ecological context of the Lewis and Clark story, and engender public support for the park mission and management activities. Although NPS does not manage non-park lands, information about trends in the distribution of elk use will be valuable in public outreach and discussions with other partnering agencies and regional private landowners.

Shrimp U Pb zircon age evidence for Paleoproterozoic sedimentation and 2.05 Ga syntectonic plutonism in the Nyong Group, South-Western Cameroon: consequences for the Eburnean Transamazonian belt of NE Brazil and Central Africa  

NASA Astrophysics Data System (ADS)

The Nyong Group of the NW corner of the Congo craton is a metasedimentary and metaplutonic rock unit that underwent a high-grade tectono-metamorphic event at ˜2050 Ma associated with charnockite formation. However, the age of the sedimentation and associated plutonism was not known. In view of this, the unit was considered to be part of the Archean Congo craton reactivated during a Paleoproterozoic or a Pan-African orogeny. Such interpretation was widely supported by the persistence of Archean inheritance revealed by Nd isotope data on whole rocks and U Pb on zircons. New SHRIMP analyses on detrital zircons from metasediments (BIF, orthopyroxene gneiss and garnet gneiss) yield Mesoarchean to Paleoproterozoic ages, with the youngest zircon at 2423 ± 4 Ma, thus giving the maximum deposition age for the Nyong Group. Data on a metagranodiorite at Bonguen and a metasyenite at Lolodorf yield emplacement ages of 2066 ± 4 Ma and 2055 ± 5 Ma respectively, with Archean inheritance (2836 ± 11 Ma) for the metasyenite. The syntectonic emplacement of these plutonic rocks is supported by the age of 2044 ± 9 Ma obtained on the Bienkop charnockite, associated with Eburnean high-grade metamorphism which continued probably up to 1985 ± 8 Ma. These new data permit correlation of the Nyong rocks with the Paleoproterozoic of NE Brazil and the discussion of the source provenance of detritus for the Nyong Group. Finally, it is proposed that the West Central African Belt (WCAB) in southern Cameroon, Gabon, Congo and Angola represents a segment of the Eburnean Transamazonian orogeny that resulted from the convergence and collision between the São Francisco-Nigerian Shield block and a former Congo megacraton.

Optimal parking orbits for manned Mars missions  

NASA Astrophysics Data System (ADS)

This paper summarizes a Mars parking orbit optimization effort. This parking orbit study includes the selection of optimal elliptic Mars parking orbits that meet mission constraints and that include pertinent apsidal misalignment losses. Mars missions examined are for the opportunity years of 2014, 2016, and 2018. For these mission opportunities, it is shown that the optimal parking orbits depend on the year that the mission occurs and are coupled with the outbound, Mars stay, and return phases of the mission. Constraints included in the parking orbit optimization process are periapsis lighting angle (related to a daylight landing requirement), periapsis latitude (related to a landing latitude range requirement) and the vehicle Trans-Earth-Injection stage mass. Also, effects of mission abort requirements on optimal parking orbits are investigated. Off-periapsis maneuvers for Mars orbit capture were found to be cost effective in reducing the mission delta-V for the 2016 abort from Mars capture scenario. The total capture and departure delta-V was `split' between the capture maneuver and the departure maneuver to reduce the 2016 Mars departure delta-V to below the level of the corresponding stage of the 2014 baseline mission. Landing results are provided that show Mars landing site access from the optimal elliptic parking orbits for Mars excursion vehicles with low (0.2) and high (1.3 and 1.6) lift to drag ratio.

The quandary of local people—Park relations in Nepal's Royal Chitwan National Park  

NASA Astrophysics Data System (ADS)

This paper analyzes five major causes of park-people conflicts that have occurred in Nepal's Royal Chitwan National Park. The causes include illegal transactions of forest products from the park, livestock grazing in the park, illegal hunting and fishing, crop damage, and threats to human and animal life caused by wild animals from the park. The conflicts indicate a reciprocal relationship between the park and local people. They reflect the attitudes of local people and representatives of the park authority whose priorities and objectives largely diverge. The results show that people settled adjacent to the park are heavily dependent on its resources. Even in places where some, albeit few alternative sources exist, local people continue to trespass the park boundary as these sources are inadequate to ensure the fulfillment of local people's resource needs. Illegal transactions of resources continue throughout the year; however, they are less intense during summer due to flooding caused by the Rapti River, which forms the park boundary towards the northern section where this study is conducted. The frequency of local people's visits to the park is mainly determined by their age, distance between homesteads and park, and volume of crop loss caused by wild animals. Crop damage is the function of size of landholding, distance, and frequency of crop raid. Local people claim that they have no intention of letting their livestock graze in the park; however, the dense vegetation of the park attracts livestock grazing on riverbanks just outside the open park boundary. Many head of livestock are killed by carnivores of the park. Human casualties are mainly caused by sloth bear ( Melursus ursinus), tiger ( Panthera tigris), wild pig ( Sug scrofa), and rhinoceros ( Rhinoceros unicornis). There had been some earlier attempts to reconcile the conflicts by offering local people different kinds of compensations; however, these were unsuccessful measures. An integrated approach is essential if efforts to resolve the park-people conflicts are to succeed. The government is in the process of launching a project that aims to resolve the inherent problems with such an approach. Suggestions are made to incorporate some key elements, such as maintaining effective communication between various parties and the potential for wildlife conservation among local people.

Fishes of the Adirondack Park  

SciTech Connect

This review of the ichthyology of the area of the Adirondack Park contained within the blue line centers on biological surveys of the six major watersheds of the study area done in 1930-1935. The total area of 9261 square miles contains 2000-3000 water bodies. The ichthyofauna consists of 96 forms, including four kinds of hybrids commonly produced and used in stock programs; of the remaining 92 forms, 23 may be classified as Boreal or peri-glacial. The Atlantian group consists of 20 species and the Mississippian and adjacent Pleistocene refugia have provided about 45 members of the fauna. Two of the fauna are the rainbow and steelhead trout and the Kokanee salmon, introduced from the west coast; three species are from the old world. Spraying for insect control, introduction of exotic plant species, and acid precipitation have all measurably impacted fish populations in recent years, often in complex and synergistic ways. For example, a decline of fish populations in Big Moose Lake is probably the complex result of present and past lumbering, fishing, stocking, forest fires and hurricane damage, as well as acid precipitation. As the system diversifies, many populations of Boreal forms are being lost, and new forms of Atlantian and Mississippian heritage are being established. 253 references, 7 tables.

Holocene climate in the western Great Lakes national parks and lakeshores: Implications for future climate change  

USGS Publications Warehouse

We reconstruct Holocene climate history (last 10,000 years) for each of the U.S. National Park Service units in the western Great Lakes region in order to evaluate their sensitivity to global warming. Annual precipitation, annual temperature, and July and January temperatures were reconstructed by comparing fossil pollen in lake sediment with pollen in surface samples, assuming that ancient climates were similar to modern climate near analogous surface samples. In the early Holocene, most of the parks experienced colder winters, warmer summers, and lower precipitation than today. An exception is Voyageurs National Park in northern Minnesota where, by 8000 years ago, January temperatures were higher than today. The combination of high mean annual temperature and lower precipitation at Voyageurs resulted in a dry period between 8000 and 5000 years ago, similar to the Prairie Period in regions to the south and west. A mid-Holocene warm-dry period also occurred at other northern and central parks but was much less strongly developed. In southern parks there was no clear evidence of a mid-Holocene warm-dry period. These differences suggest that global model predictions of a warm, dry climate in the northern Great Plains under doubled atmospheric CO2 may be more applicable to Voyageurs than to the other parks. The contrast in reconstructed temperatures at Voyageurs and Isle Royale indicates that the ameliorating effect of the Great Lakes on temperatures has been in effect throughout the Holocene and presumably will continue in the future, thus reducing the potential for species loss caused by future temperature extremes. Increased numbers of mesic trees at all of the parks in the late Holocene reflect increasing annual precipitation. This trend toward more mesic conditions began 6000 years ago in the south and 4000 years ago in the north and increased sharply in recent millennia at parks located today in lake-effect snow belts. This suggests that lake-effect snowfall is sensitive to continental-scale changes in climate and could be affected by future climate change. Plant and animal species sensitive to changes in the moisture regime could thus be endangered within the Great Lakes parks.

Brazil & the Latin American Economy  

NSDL National Science Digital Library

This week's In the News follows repercussions of world financial crises in the key Latin American economy of Brazil. The nine resources discussed provide background information, press coverage, and economic data on Brazil and related economies. With a population of 164 million and GDP of $480 billion, Brazil represents Latin America's largest economic force. Heavy US financial investments, however, tie Brazil directly to Dow Jones Industrial Average falls (reviewed in the September 10, 1998 Scout for Business & Economics) and their Asian and Russian causes (reviewed in the July 16, 1998 _Scout Report for Business & Economics_--http://scout.cs.wisc.edu/report/bus-econ/1998/be-980716txt.html#22). International concern for Latin America grew when Brazil lost $1.8 billion in foreign capital following drops in the Dow, September 10, 1998--a decisive factor in stock tumbles in Mexico and Venezuela as well. Such damaging results led to a bold rise in interest rates from the Banco Central do Brasil and negotiations with the IMF. A US and Brazilian market rally since September 11, however, leaves many officials hopeful for a stable Latin American future.

[Recreational attraction of urban park wetlands in Beijing].  

PubMed

Taking the 20 urban park wetlands in Beijing as test objects, a 3-layer evaluation index system including urban park wetland landscape quality, location condition, and accessibility for the recreational attraction of urban bark wetlands was established, and, by using analytic hierarchy process (AHP) and an integrating index evaluation method, the recreational attraction of the urban park wetlands in Beijing was quantitatively assessed, and validated with questionnaire data. In Beijing, the urban park wetlands with high recreational attraction were in the order of the Summer Palace, Olympic Park, Qinglong Lake Park, Beihai Park, Yuanmingyuan Park, Yuyuantan Park, Shidu, Golden Sea Lake scenic area, Taoranting Park, and Yeyahu wetland. The Rice Fragrance Lake wetland and Zhenzhuhu scenic area had the lowest recreational attraction, and the others were fair. The evaluation results were supported by the questionnaire data, which indicated that the index system and evaluation model were useful. According to the recreational services, the 20 park wetlands in Beijing could be clustered into four categories, which could be managed in different ways. Appropriately assessing the recreational services of urban park wetlands could help the decision-making on the urban parks optimal planning and designing, improve human living environment, and optimize the spatial distribution of urban landscape.

Lichens of the U.S. National Parks  

USGS Publications Warehouse

Over 26,100 records of lichens present in 144 U.S. national park units were assembled from various sources into a database and analyzed. Within these 144 park units 2,435 species and 375 genera are reported, representing 63% and 74% of the North American flora, respectively. The park units are located in 41 states and Washington, D.C. The average number of species in a park is 104, but the median is 60, indicating there are many parks with a small number of species and a few with high numbers. Isle Royale National Park has the most species, 611, and twelve parks have only one species reported. The number of records of lichens present ranged from one for 25 parks, to 1,623 for Isle Royale. Physcia aipolia is the most frequently observed species, being found in 65 parks. One fourth of the park units are classified cultural resource parks, while the remainder are considered natural resource parks. This study was based on 453 sources, including literature citations, park reports and collections in the University of Minnesota Herbarium.

The Parkes 21 CM multibeam receiver  

NASA Astrophysics Data System (ADS)

Several extragalactic HI surveys using a 21-cm 13-beam focal plane array will begin in late 1996 using the Parkes 64-m telescope. These surveys are designed to detect efficiently nearby galaxies that have failed to be identified optically because of low optical surface brightness or high optical extinction. We discuss scientific and technical aspects of the multibeam receiver including astronomical objectives, feed, receiver and correlator design and data acquisition. A comparison with other telescopes shows that the Parkes multibeam receiver has significant speed advantages for any large-area 21- cm galaxy survey in the velocity range range 0 - 14000 km per sec.

Parks, Place and Pedagogy - Education Partnerships with the National Park Service  

NASA Astrophysics Data System (ADS)

The Michigan Teaching Excellence Program (MITEP) is a multi-year program of teacher leadership development that empowers science teachers in Grand Rapids, Kalamazoo, and Jackson to lead their schools and districts through the process of improving science teaching and learning. A component of this program is facilitated through partnership between academia, K-12 educators, and the National Park Service (NPS) that aims to develop place-based education strategies that improve diversity and Earth Science literacy. This tangible education method draws upon both the sense of place that National Parks offer and the art of interpretation employed by the park service. Combined, these deepen cognitive process and provide a more diverse reflection of what place means and the processes behind shaping what we see. Our partnerships present participants the opportunity to intern in a Midwest national park for 3-8 weeks during their third year in the program. In summer 2011, eleven teachers from the Grand Rapids school district participated in this innovative way of learning and teaching Earth Science. One goal was to develop geological interpretive materials desired and needed for the parks. Secondly, and important to place-based educational methodologies, these deliverables will be used as a way of bringing the parks to urban classrooms. Participants lived in the parks and worked directly with both national park and Michigan Tech staff to create lesson plans, podcasts, media clips, video, and photographic documentation of their experiences. These lesson plans will be hosted in the Views of the National Park website in an effort to provide innovative teaching resources nationally for teachers or free-choice learners wishing to access information on Midwest national parks. To the benefit of park staff, working with teachers from urban areas offered an opportunity for park staff to access diverse learners in urban settings unable to visit the park. The foundation has been laid for future work in this program aiming to develop a stronger appreciation of environment and geological processes and connections between what K-12 students do and their impact on Earth systems. This paper presents preliminary results of the following evaluation methods: 1) pre-post surveys administered to examine depth and breadth of geological knowledge, awareness of cultural significance, and emotional meanings and attachments toward the park, and 2) semi-structured interviews with participants, park staff, and academic faculty to determine how these programs can be best implemented and improved in both parks and classrooms alike. Learning about Earth system processes can be fostered by employing different ways of knowing, or the art of interpretation. It is hoped that this engagement between teachers, parks, and academia will increase diversity in Earth Science, enrich Earth Science curriculum, and help develop a sense of place for students
