The bats (Mammalia: Chiroptera) of the Argentine Chaco

Abstract

The Western and Eastern Chaco have the largest number of species with 31 each, while the Central Chaco has only 14 species. This difference in richness is related to contact of the Chaco with humid and transitional habitats adjacent to the western and eastern subregions. A comparison with the bat faunas of the Chaco of Paraguay and Bolivia is given, as well as comments about taxonomy, feeding guilds, abundance, and reproduction. -from Authors
