MARTINS, Ana C. M.; BERNARD, Enrico; GREGORIN, Renato  e  SILVA, Wanuyze A. S. da. Filling data gaps on the diversity and distribution of Amazonian bats (Chiroptera): the case of Amapá, easternmost Brazil. Zoologia (Curitiba, Impr.) [online]. 2011, vol.28, n.2, pp. 177-185. ISSN 1984-4670.  http://dx.doi.org/10.1590/S1984-46702011000200004.

Brazil is the second most bat species-rich country in the world, but the information on its species diversity, occurrence and distribution is still heterogeneous and fragmented. None of the Brazilian biomes are well surveyed for bats, but this situation is more critical in Amazonia, an area covering nearly 2/3 of the country. Here we provide updated information on the bats of Amapá, once a data gap in the diversity and distribution of bats in the easternmost Amazonia, and the Guiana Shield as well. Rapid biological assessments (5,551 mistnet.hours) were conducted in conservation units and areas of concern, resulting in 1,695 captures, 59 species, 36 genera and six families for the State. New records for the state and for the Guiana Shield area are reported. With our records, 82 species of bats are currently known in Amapá, filling a gap in the knowledge of bat fauna in the Amazon River's delta region.
