Biogeography and priority areas for the conservation of bats in the Brazilian Cerrado
In this study, we describe the distribution pattern of bat species and select priority areas for the conservation of the Cerrado based on a systematic planning approach. We estimated species richness and calculated the total beta diversity based on Sørensen’s dissimilarity index (βsor). We estimated the species turnover using Simpson’s dissimilarity index (βsim). We then evaluated the nesting (βsne) by the difference between the dissimilarity indices (βsor and βsim). Based on this analysis, we identified the priority areas for the conservation of bats in the Cerrado based on the zonation approach. We found that the species richness and beta diversity of bats in the Cerrado are concentrated primarily in the central and northern portions of the biome. We also discovered that the conservation units of the Cerrado are ineffective for the protection of species with a restricted distribution (≤ 150 grid cells), such as Vampyrum spectrum, for which we propose the creation of new conservation units that better cover the diversity patterns observed in the present study. By conserving this diversity, we will also be protecting local habitats, which will in turn enable the survival of a wide range of species, and provide the ecosystems with the capacity to respond adequately to future changes in the environment.
