AbstractStudies on bat ecology and distribution in the Brazilian Cerrado are scarce. Here we describe a bat assemblage from a savanna landscape in central Brazil and explore the richness, diversity, abundance and the influence of habitat and seasonality. We conducted 48 nights of sampling in both dry and wet seasons and in three habitat types. We estimated the richness and diversity indexes. We assessed the influence of habitat and season on species abundance with a generalized linear mixed model. Overall, we captured 254 individuals of 19 species and our effort sampled 90% of the estimated richness. The Phyllostomidae family was the most frequent, with 76.3% of all captures.
