| Abstract | |
In order to investigate the effects of habitat loss and fragmentation of the Atlantic Rain Forest in leaf-litter anuran and lizards we sampled 15 fragments and six localities of continuous forest in the Tapiraí and Piedade region, Atlantic Plateau of São Paulo. Forest fragments supports a higher species richness in comparison to other studies developed in the Atlantic Plateau, but mainteined lower diversity than continuous forest localities. Differences in species composition among localities can be explained by geographic distance, forest and vegetation structure and microhabitat disponibility. The effects of isolation increase and area reduction in leaf-litter anurans were correlated to species natural history, and constituted important characteristics to diversity conservation in this region. Our study suggests that leaf-litter anurans and lizards distribution and persistence in fragmented landcapes could be determined by an interaction of fragmentation effects and ambiental disturbance.
