Comunidades de anfíbios no baixo rio bonito no estado de Goiás– Brasil

Abstract

The Cerrado biome is one of great importance, being part of the 25 global "hotspots”. In the Cerrado are present 209 species of amphibians found in the Cerrado, where 51.7 % are endemic, and new species are still being described and some areas have not been adequately sampled. The study aimed to show the richness and abundance of amphibian communities, with respect to seasonality and patterns of habitat use in Cerrado of lower river Bonito, State of Goiás hold two sampling campaigns: the first was held in January 2011 and the second in July 2012. We determined 10 sampling transects, with 5 points on each bank. Effective sampling with pitfall traps were used and fall (pit-fall associated with driftfences), active samples (sweeps) and auditory method (vocalization). We recorded 411 individuals of the class Amphibia, over 1 order, 6 families, 11 genera and 26 species. Os trasectos 1, 2, 3 and 4 showed higher abundance because they are environments that present vegetation types of gallery forests and paths, since transects 5, 6, 7, 8, 9 and 10 there was little abundance , being a transformed by the action of men.The rainy season showed higher abundance of species, and the vast majority of them are prevalent this time area. During the dry season had a predominance of species as Rhinella schneideri and Physalaemus cuvieri. This study has great importance, so there is a better understanding of the distribution of amphibians in the Cerrado biome.
