Abstract
Neotropical forests show high anuran species richness, but some Brazilian forest formations, like cerradão, semideciduous forests and restingas, remain poorly known. The composition of anuran species were determined for four forest sites belonging to different biomes in southeastern Brazil, based on two complementary techniques (visual encounter survey and survey on breeding sites), both applied simultaneously. A total of 60 anuran species belonging to eight families was recorded. Species richness and levels of endemism were higher in the Atlantic rainforest site. Sites located in the Cerrado domain were more alike than those located in the Atlantic Forest Domain. Similarity in anuran species composition was negatively correlated to the geographical distance among sites, which explains part of similarities in species composition. Factors affecting these occurrence patterns are discussed. One species (if its identity is confirmed) is considered Data Deficient by IUCN (The World Conservation Union), though it is not included in the Brazilian list of threatened amphibians. The presence of certain species with special habitats and microclimate requirements (bioindicators) suggests well-preserved ecosystems.
As florestas neotropicais apresentam altas riquezas de espécies de anuros, mas algumas formações florestais brasileiras, como o cerradão, as florestas semidecíduas e as restingas, permanecem pouco conhecidas. A composição de espécies de anuros de quatro áreas florestais pertencentes a diferentes biomas do sudeste do Brasil foi determinada com base em duas técnicas complementares (procura visual e investigação nos sítios reprodutivos), aplicadas de forma simultânea. Registramos um total de 60 espécies de anuros, incluídas em oito famílias. A riqueza de espécies e o nível de endemismo foram maiores na área coberta por floresta pluvial atlântica. As áreas localizadas no domínio do Cerrado foram mais similares entre si do que as áreas localizadas no domínio da Mata Atlântica. Os índices de similaridade mostraram-se negativamente relacionados com a distância geográfica entre as áreas, explicando parte das similaridades observadas. Os fatores que influenciam os padrões de ocorrência são discutidos. Uma das espécies (caso sua identidade seja confirmada) é considerada como Deficiente em Dados pela IUCN (The World Conservation Union), mas não está incluída na lista da fauna brasileira ameaçada de extinção. A presença de certas espécies com requisitos especiais de hábitat e microclima (bioindicadores) sugerem que os ecossistemas estão bem-preservados.
