Popis: A central issue for ecologists is to understand the variables that determine species distribution. Many studies have suggested that environmental variables are the main factors that shape anuran communities. Nevertheless, several natural environments have not been assessed with ecological studies of this nature, including specific ecosystems of the South American Cerrado morphoclimatic domain. In the present study, we investigated the relationship between environmental variables and the spatial distribution of anurans in ecosystems of semi-deciduous and riparian forests in a transitional region between the Cerrado and Caatinga environments in the western Bahia state, Brazil. We collected fauna and environmental variables data in 10 sampling units during two rainy periods. The original information on species composition and abundance in the community was reduced to a single axis using a non-metric multidimensional scaling method (NMDS) and environmental data were reduced to two main factors using...
