AbstractThe richness and abundance of adults and tadpoles of anuran amphibians were studied during 15 months in ten water bodies, in Nova Itapirema, São Paulo, Brazil, region that was intensively impacted by agricultural activities. Twenty-seven species of anurans were registered, and among them four species were new records for this region. Most species are typical from open areas, and the higher richness and species diversity were found in lentic water bodies. However, due to the few water bodies in fragments of riparian forest, comparisons among water bodies in open area and in fragments of riparian forest were not possible. Six descriptors of water bodies heterogeneity were determined, but no one was related with the species richness. On the other hand, both richness and abundance of species were strongly correlated with climatic variables. The species composition (b diversity) was similar among the water bodies, which probably reflect the great niche breadth, typical of species from unstable or modified environments. The anuran richness observed in the studied region is similar to other localities where the level of environmental conservation is higher, as the Estação Ecológica de Águas Emendadas (Federal District) and the Floresta Nacional de Silvânia (Goiás).
