Dinâmica de anfíbios em áreas palustres no Parque Nacional da Lagoa do Peixe

Abstract

Wetlands are important ecosystems for conservation, due to the great biodiversity they support. Anuran amphibians are important components of the biological communities in southern Brazil wetlands. Lack of data is one of the main restrictions to conservation programs. In this sense, studies on diversity, species richness, geographic distribution, and ecology of anuran populations are needed. Hydroperiod and habitat diversity are important factors influencing species distribution and communities structure in anurans. However, there are no such data for adult anurans and tadpoles in wetlands of coastal dunes in southern Brazil. The aim of this study was to test whether habitat diversity and hydroperiod can be related to spatial and temporal distribution of anurans in wetlands of coastal dunes in Rio Grande do Sul. Besides, we tested whether anurans composition were associated to structural features. These features were area, numbers of drought, months of drought, anuran predator richness, floating vegetation,
