Anurans of the cerrado of the Estação Ecológica and the Floresta Estadual de Assis, southeastern Brazil

Abstract

The Brazilian cerrado is a hotspot of biodiversity, areas with many endemic species subjected to severe habitat loss. About 150 amphibian species are known to the Brazilian cerrado, and 28% of them are endemic. Studies focusing cerrado anuran communities are rare. Here we provide a commented list of anurans of two conservation unities of the municipality of Assis, southeastern Brazil: the Estação Ecológica de Assis and the Floresta Estadual de Assis. Twenty three anuran species were recorded, and these belong to 13 genera and six families. The anuran fauna of the cerrado of Assis is dominated by the families Hylidae (eight species) and Leptodactylidae (six species), a pattern commonly found in neotropical sites. Species richness and taxonomic composition at the family level were similar to those of other Brazilian cerrados and perturbed areas characterized by deforestation and increase of open areas. The taxocenosis contains species widespread in open formations of the Cerrado-Caatinga-Chaco complex.
