The Caatinga is the only endemic Brazilian biome, and covers part of eight Brazilian states, mainly in the Northeast, with a total area of 735,000 km2. Its principal characteristics include a high mean annual temperatures and evapotranspiration, and a low annual precipitation, between approximately 240 mm and 1500 mm, with low relative humidity. The vegetation is composed mainly of dense, spiny shrubs adapted to the region s semi-arid conditions. The difficulties of conducting research under these conditions led to the traditional view of the Caatinga as a biome of low species diversity and endemism. However, a number of recent studies have demonstrated a relatively rich fauna and flora, including 143 species of mammals, more than half of them bats. While these animals represent three-quarters of the mammalian fauna of the Caatinga, only one species is considered to be endemic. While there have been considerable advances in the scientific knowledge on the bats of Caatinga, only 7% of its area can be considered minimally surveyed, with many data gapsfor thatregion. Data on the reproduction, systematic, diet, and distribution of bats are available for a small number of localities. In Sergipe, a total of 37 species are known to occur, although few sites have been surveyed up to now. The present study aimed to provide data on a bat community of the Caatinga in Sergipe, analyzing aspects of the ecology of this group in a relatively well-preserved habitat, with unique characteristics that have a major potential for the conservation of the region s flora and fauna.
