Bats (Mammalia: Chiroptera) from a remnant of Atlantic Forest in Pernambuco, northeastern Brazil / Morcegos (Mammalia: Chiroptera) de um remanescente de Mata Atlântica em Pernambuco, Nordeste do Brasil

The RPPN Carnijó (08° 07’ 07” S, 35° 05’ 32” N) is a 25 hectare fragment of Atlantic Forest located in the municipality of Moreno, Pernambuco. Bats were sampled at this site during a total of 19 months between 2006 and 2008. Four mist-nets were set for six hours each night along trails, the forest edge, natural clearings, and over watercourses, while roosts were located during daytime searches. A total of 518 specimens were captured during 43 nights, representing 20 species in 16 genera. Total species richness was estimated to be 25.7 ± 2.0, and diversity was H’ = 2.07. The family Phyllostomidae predominated, with 98% (N = 509) of the specimens captured. The species recorded represent 28% of the known chiropteran fauna of the state of Pernambuco. The results indicate that the reserve may play a fundamentally important role in the maintenance of local biodiversity by acting as a “stepping stone” linking the larger fragments within the local landscape.

Os morcegos foram amostrados durante 19 meses, entre 2006 e 2008. Quatro redes de neblina foram armadas por seis horas em cada noite em trilhas no interior da área florestada, na borda, em clareiras naturais e próximas a córregos e alagados. Buscas por abrigos foram realizadas durante o dia. Um total de 518 espécimes foram capturados em 43 noites de amostragem, representando 20 espécies de 16 gêneros. A riqueza foi estimada em 25,7 ± 2,0 e a diversidade foi H’ = 2,07. A família Phyllostomidae predominou com 98% (N = 509) das espécies capturadas. As espécies registradas no presente estudo representam 28% da quiropterofauna conhecida para o estado de Pernambuco. Os resultados indicam que a RPPN Carnijó pode desempenhar um importante papel na manutenção da biodiversidade local atuando como “trampolim ecológico” na paisagem local.

Updated compilation of bat species (Chiroptera) for the Brazilian state of Sergipe, including new records

This article is a summary study of the existing knowledge related to the occurrence and distribution of bat species in Sergipe, Northeastern Brazil, and includes new records of Peropteryx macrotis (Wagner, 1843) and the first record of Diphylla ecaudata Spix, 1823 for this state. The specimens were captured in groundlevel through the use of mist-nets on the Fazenda Mundo Novo (9º 38’31” Lat S, 37º 47’ 18” Long W) under the municipality of Canindé do São Francisco. The morphology of the specimens was compared with previous descriptions of the respective species available in the scientific literature. A total of 43 bat species belonging to 31 genera and eight families (Phyllostomidae = 29 species; Emballonuridae = 3; Molossidae = 3; Noctilionidae = 2; Vespertilionidae = 2; Mormoopidae = 2; Furipteridae = 1; Natalidae = 1) are now known as occurring in Sergipe. Among them, 20 species are found in the Caatinga (10 endemic), and 32 in the Atlantic Forest (20 endemics). The registered richness represents 24.4% of the bat fauna recorded in Brazil. Despite the relatively small size of the Sergipe state (approximately 22,000 km²), much of its area remains unsurveyed, and further studies are clearly necessary in order to define the true diversity of its chiropteran fauna. In particular, the subterranean ecosystems demand special attention due to not only the paucity of data available for these environments, but also the considerable anthropogenic pressures they suffer, facts that may threaten the existence of these unique habitats and the bats that depend on them.

Extension of the geographical distribution of Lonchophylla dekeyseri Taddei, Vizotto and Sazima, 1983 (Chiroptera: Phyllostomidae): New record in northeastern Brazil

This paper aims to extend the geographical distribution of Lonchophylla dekeyseri  in Brazil, as well as to register its first record in the State of Paraíba, northeastern Brazil. This record was based on two captured specimens, one male and one female. Measures and qualitative morphological characters were in accordance to those described in the literature. The city of Buíque, State of Pernambuco, located approximately 570 km away from the last record of L. dekeyseri in the Caatinga biome, is now the orient al limit of known geographical distribution for this species in Brazil.
