In this study, we sought to analyze the extent to which changes in the parameters of a community of anurans in an Atlantic Forest area could be explained by the seasonal changes in some environmental factors such as precipitation and temperature. Our study was carried out in the Vale Natural Reserve, located in Linhares, Espírito Santo, Southeastern Brazil, between June 2015 and May 2016. To sample the community we use 21 plots of 250 meters, 1km away from each other, following the RAPELD methodology. We recorded a total of 326 individuals of anurans, corresponding to 23 species, belonging to 6 families. We conclude that the anurans community of the Vale Natural Reserve remained relatively stable in terms of species richness and composition, and in their structure between seasons and that the parameter that most varied seasonally were the general abundance of anurans and the specific abundances, with lower abundance values generally occurring during the dry season. Our study provides the first data on the effects of seasonality on the composition, richness and abundance of an anuran amphibian community for the Vale Natural Reserve area and for a Tabuleiro Forest area in Espírito Santo, Southeastern Brazil.
