Seasonal and habitat structure of an anuran assemblage in a semideciduous forest area in Southeast Brazil

Abstract

In this study, we evaluated the reproductive activity and the temporal and spatial distributions of anuran assemblages in three environments within a semideciduous forest in Southeast Brazil, located at Municipality of Barão de Monte Alto, State of Minas Gerais, Brazil. The field activities were carried out during three consecutive days, monthly throughout the rainy seasons of 2013–2014 and 2014–2015. We recorded 28 anurans species, distributed in eight families. We observed the spatial-temporal distribution of some species, and their associated reproductive behaviors through exploration of vocalizations at different sites. The spatial and temporal distribution of the species seems to adapt to abiotic and biotic factors of their environment.
