Bats (Mammalia, Chiroptera) in a remnant of Atlantic Forest, Rio de Janeiro, southeastern Brazil
Biodiversity inventories are essential to generate information leading to the proposal of conservation plans, especially for threatened areas. Despite being one of the best sampled regions for bats in Brazil, some areas of Rio de Janeiro still represent knowledge gaps. Between May 2011 and June 2012, we performed 36 nightly samplings to conduct an inventory of bat species in Reserva Ecológica de Guapiaçu, in Cachoeiras de Macacu, in the state of Rio de Janeiro, southeastern Brazil. We used 10 mist-nets per night opened from sunset to sunrise. A total of 1,290 individuals belonging to 31 bat species were caught. They were distributed in three families, Phyllostomidae (24 species), Vespertilionidae (four species) and Molossidae (three species). We recorded two other species of two families, Noctilionidae and Thyropteridae, by direct observations. The species richness of bats in Reserva Ecológica de Guapiaçu is one of the largest ever recorded in the Atlantic Forest.
