Abstract Aim To investigate the influence of ecological factors, geologic and climatic history on current diversity patterns bat communities. We predicted that (i) our three different biodiversity dimensions (species richness, functional phylogenetic diversity) will have a positive relationship with habitat heterogeneity; (ii) variation in be positively influenced by elevation; (iii) stability, less regions higher instability. Location Neotropical Savannah (Cerrado). Methods calculated nine metrics: species diversity, mean paired distance (MFD) distances (MPD), richness‐corrected (SES‐FD), (SES‐PD) (SES.MFD SES.MPD) using distribution records for 111 species. Habitat heterogeneity, variables, elevation, floristic stability were used as independent variables. hierarchical Bayesian models to spatialise based best predictors. Results Cerrado heterogeneity is important distances. Precipitation, temperature, most predictors biodiversity. Species richness inversely related instability, which predictor this metric. There decline where composition has been more altered during last 30,000 years, mainly southern Cerrado. Main Conclusions Present‐day historical factors simultaneously explain communities major driver bats, closely lineages share habitats homogeneous vegetation. changes observed metrics (PD FD) ones corrected (SES‐PD SES‐FD) opposite ways. indicate filtered adaptive traits occupied
