It is predicted that climate change will cause species extinctions and distributional shifts in coming decades, but data to validate these predictions are relatively scarce. Here, we compare recent historical surveys for 48 Mexican lizard at 200 sites. Since 1975, 12% of local populations have gone extinct. We verified physiological models extinction risk with observed extended projections worldwide. estimate 4% extinct worldwide, by 2080 projected reach 39% may 20%. Global were validated...
The effects of Brazil´s political crisis on biodiversity conservation are likely to be global. Brazil is not only the World´s most biodiverse nation, it responsible for greater part Amazon forest, which regulates climate and provides rain much southern South America. was a World leader in satellite monitoring land-use change, in-situ monitoring, reduction tropical-forest deforestation, protection indigenous lands, model other developing nations. Coordinated public responses will necessary...
Several species of Glaucomastix lizards have been described over the past decade, most these inhabit inland Brazil. abaetensis is a threatened whiptail endemic to Brazilian coastal "restinga" (sandy habitats) from Bahia State Sergipe, with distribution limited by riverine barriers. In order investigate differentiation and relationships in G. abaetensis, we integrated phylogeographic analysis, Bayesian delimitation morphological data detect geographical patterns historical events responsible...
The thermal biology and flight distance of the tropical lizard Tropidurus oreadicus was studied on iron ore outcrops (called canga) at Serra dos Carajas, in Brazilian Amazonia. Body temperature varied markedly throughout day (range 32.0 to 38.1 °C), but mean preferred body 35.8 °C. air microhabitat explained a considerable part variation, other factors such as direct insolation substratum teperature may also be importance. In morning, lizards usually climbed onto rocks assumed progressively...
In this study we review the records regarding occurrence of Hemidactylus mabouia Moreau De Jonnès, 1818 in Brazil, looking for species natural habitats, order to assess present status gecko as an exotic or invasive alien country. We surveyed available H. living conditions, considering secondary data obtained from literature, supplemented with original field by authors during fieldwork. found a total 36 literature and/or reporting habitats different localities 13 Brazilian states. The states...
Morphological similarity associated to restricted distributions and low dispersal abilities make the direct developing “Terrarana” frogs of genus Euparkerella a good model for examining diversification processes. We here infer phylogenetic relationships within Euparkerella, using DNA sequence data from one mitochondrial four nuclear genes coupled with traditional Bayesian reconstruction approaches more recent coalescent methods species tree inference. also used clustering analysis...
Abstract Natural environments disturbed by human activities can suffer from species extinctions, but some still harbor high taxonomic diversity. However, disturbances may have impacts beyond the level, if lost represent unique functions in ecosystem. In this study, we evaluated to what extent amount of habitat determine functional diversity and nestedness amphibian communities an Atlantic Forest fragmented landscape Brazil, there is a threshold which severe loss As responses depend on their...
Understanding the effects of random versus niche-based processes on biodiversity patterns is a central theme in ecology, and an important tool for predicting habitat loss fragmentation biodiversity. We investigated predictive power to explain species richness dissimilarity amphibian assemblages fragmented tropical landscape Atlantic Forest South America. analyzed large database abundance occupancy, sampled 21 forest fragments ranging size from 1.9 619 ha. compared observed with outcomes two...
ABSTRACT The high diversity of amphibians in the central Amazon Rain Forest allowed us to examine influence tadpole antipredator defenses on assemblage structure and composition within bodies water (α diversity) among aquatic sites (β at a local scale. During three‐year study composition, we found that anuran community used variety for reproduction; these ranged from streams streamside ponds isolated forest ponds. distribution several species was negatively related fish density, while other...
The scincids Mabuya macrorhyncha and M. agilis occur sympatrically syntopically at the Barra de Marica restinga, in Rio Janeiro State, Southeastern Brazil. use of three different niche dimensions (space, food, time) by two species was compared certain morphometric differences between them were analyzed. differed considerably microhabitat both horizontally vertically. strongly associated with bromeliads, while found mainly on leaf-litter had a low degree arboreality. Both unimodal activity...

Biodiversity corridors comprise a mosaic of land uses connecting fragments natural forest across landscape. Two such have been established along the eastern coast Brazil: Serra do Mar and Central da Mata Atlântica corridors, which most coastal plains are restinga areas. In this study, we analyze present status endemic endangered terrestrial vertebrates both corridors. We sampled 10 restingas in recording species amphibians, reptiles, birds, mammals. Some harbor relatively large number...
The reproductive and fat body cycle of the tropidurid lizard Liolaemus lutzae was studied in tropical seasonal habitat Restinga da Barra de Marici Rio Janeiro, southeastern Brazil. Females have a marked seasonality reproduction (September to March), possibly correlated with rainfall. store bodies during drought periods, investing it production first clutch beginning season. Recruitment juveniles began middle December ended May-June following year. minimum size at maturity for females (51.5...
Abstract In a ‘restinga’ habitat of southeastern Brazil, we studied the food habits and microhabitat use two lizards with distinct foraging modes: tropidurid Tropidurus torquatus, sit‐and‐wait predator, teiid Cnemidophorus ocellifer, wide forager. The diet species differed strongly, indicating low level similarity in their trophic niche. predator fed mainly on mobile prey, whereas forager sedentary prey (larvae). spatial niche breadth T. torquatus was larger than that C. ocellifer. Despite...
