ABSTRACT
Caves are essential roosts for most species of bats and 25% of the Brazilian species were already sampled at caves. In spite of the extensive carste area observed in Brazil, few lists of cave bats are available in Brazil. We accomplished inventory in the APA Nascentes do Rio Vermelho and we compared the richness with other published samples. Twentyeight species of bats were confirmed in APANRV, of which 75% were captured at caves. The number of species of bats for each cave varied from 2 to 16, with an average of 7.54 species. Of the five caves sampledboth in the rainy season and in the dry season, three showed more species during dry season. It was not obtained significant linear relationship between the geographical distance and the Jaccard similarity among the samples. The simple regression between the observed richness and the number of sampled caves in all available Brazilian samples was significantand positive; however it was not obtained significant relationship of the richness with the latitude and the biome.
