Whole-genome sequences provide massive amounts of data that can illuminate many aspects of a species’biology and evolutionary history,as well as valuable information for conservation planning.This is particularly important for large carnivores,whose large area requirements and typical low densities make them prone to undergo rapid genetic erosion(e.***.accumulation of runs of homozygosity,Diez del Molino et al.,2018;Leroy et al.,2018)in the face of habitat loss and human persecution.One such species is the jaguar(Pan-thera onca),the largest extant felid in the Americas,whose range has already declined by>50%and some of whose remaining popu-lations have been severely impacted by human-induced habitat frag-mentation(De La Torre et al.,2018).

Understanding of resource requirements of vulnerable species is key for conservation planning.Here,we used sta-ble carbon(δ13C)and nitrogen isotopes(δ15N)of hair from giant armadillos(Priodontes maximus)to understand individual resource use.We collected hair from 19 giant armadillos analyzing 34 samples from the Brazilian Pan-tanal and compared the resource use between sexes and age classes.We also assessed the relationship of isotopic values with individuals’body mass and the habitat type used.We observed a wide variation in resource use by giant armadillos,showing that individuals consume prey that feeds on distinct resources and occupies different habitat types,indicating that there is individual variation in foraging behavior.Most giant armadillos presented a mixed diet(C3/C4 resources,forests/open areas),but a quarter of individuals had strictly C4 diets(open areas).Males are more prone to forage on C4 resources,presenting an isotopic niche 2.6-times larger than that of females.Subadults presented diets more associated with habitats with high arboreal cover(C3 resources,forests),while adults foraged more in open areas(C4 resources).This result is mirrored by the positive relationship betweenδ13C values and body mass,suggesting that larger giant armadillos tend to feed more in open areas.We observed thatδ13C values decreased as individuals increased the use of habitats with high arboreal cover.We stress the importance of con-serving the natural mosaic in the Pantanal landscape for the species persistence,given that giant armadillos require all habitat types to fulﬁll their dietary,spatial,and developmental needs.

Abiotic drivers shape seed inputs and outputs in a tropical wetland on Croton trinitatis population

Background:Predicting how natural and anthropogenic drivers shape different ecological indicators,such as plant populations along environmental gradients,can be a relevant tool for establishing management and conservation criteria of tropical wetlands.We aimed to assess the effects of seasonal flood disturbance,type of grasslands and topographical conditions on Croton trinitatis population distribution in a tropical wetland.Methods:The study was carried out in a seasonally flooded grassland(Central-West Brazil).We conducted samplings of soil on the dry and flood hydrophases of the Pantanal.We took the samples in eight seasonal ponds,with 1 km interval between them.Transects were marked during the flood period,observing the water level,one in the lowest zone,in the middle of the pond=low(ca.60 cm deep),one at the pond edge=mid(ca.30 cm deep)and one in the higher zone,on the external part=high(ca.1 cm deep).Results:The results showed that the topography,seasonality,and types of grassland determine differences in the abundance patterns of adult plants and seedlings,and seed bank and seed predation.The abiotic factors can shape plant population-related ecological processes and patterns,with outputs(germination and predation)and inputs(local dispersion and from neighbouring areas)of proportional seeds for the population maintenance in this environment.Conclusion:We emphasize the importance of these findings,to show that abiotic factors are not the only ones to be considered in ecological studies of distribution and structuring of populations in habitats with extreme seasonal events.

Effects of Biodegradable Detergents in Morphological Parameters of Liver in Two Neotropical Fish Species(Prochilodus lineatus and Astyanax altiparanae)

Indiscriminate disposal of residues of domestic and/or industrial origin in aquatic ecosystems resulting from urban activities causes concern about their effects on the fauna. Substances absorbed by animals, such as those cited above, are metabolized by the liver, as it is the main target organ of several pollutants and also exercises basic vital functions in the organism. For this reason the liver is used as the main and most reliable biomarker in environmental studies. Thus the objective of the present study was to identify hepatic alterations resulting from exposure to water contaminated by a few commercial brands of biodegradable detergents and their effects when present together with several other contaminants found in nature. For such, a solution of 1 ppm of biodegradable detergents and water from an urban lake were tested on two widely distributed native Brazilian fish (Astyanax altiparanae and Prochilodus lineatus). Several alterations were found on the liver, including cytoplasm vacuolization, nuclear displacement, macrophage recruitment and reduced liver glycogen, showing a degenerative process in the liver of the fish, due to the action of contaminants.

Traumatic brain injury (TBI) is a worldwide public health problem. Populations with a growing number of vehicles are experiencing many traumas and accidents. The highest-risk group is young men. Significant advances in neurosurgery and intensive therapy have resulted in increased survival rates of TBI patients. These higher survival rates, in turn, have led to an increasingly higher number of patients with neurological, cognitive, clinical, and social problems. This lack of knowledge about TBI has been called by some “the silent epidemic”. In recent years, studies of patients with moderate and severe TBI are increasing. Glasgow Coma Scale ≤ 8 and abnormal pupils at admission are used to determine the prognosis of patients with moderate or severe TBI. Several biomarkers such as interleukins, thiobarbituric acid reactive species, and some hormones have been studied in an effort to aid prognosis. Testosterone plays a key role in men. Thus, an understanding of androgens in TBI is essential to follow these survivors of head trauma. This review will discuss the epidemiology of TBI, its association with male hypogonadism, and possible treatments.

The Impacts of Sugarcane Expansion on Wildlife in the State of Sao Paulo,Brazil

Journal of Sustainable Bioenergy Systems 2012年第4期2卷 138-144页

Brazil has become one of the top producers and exporters of food, fibre, and bionergy in the world.The expansion of livestock and soybean production in the Amazon basin appears to be independent of the sugarcane expansion in southeastern Brazil whereas the impact of sugarcane expansion over areas of soybean plantation in previous Cerrado biome is still unknown. However, the expansion of sugarcane production in the state of S?o Paulohas been shown to cause an increase in the local abundance of rodents and result in the emergence of infectious diseases such as hantaviruses and leptospirosis in humans. In addition, with an increase in the use of agrochemicals there will be an increase in euthrophication of watercourses and soil pollution. Considering that S?o Paulo has a population of approximately 40 million people, these local impacts are relevant. Environmental law should be improved and enforced in Brazil to ensure that sugarcane production is not only economically profitable but also environmentally responsible.
