Morcegos (Mammalia, Chiroptera) em remanescente de Floresta Atlântica, Rio de Janeiro, sudeste do Brasil

Abstract

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.

Mammals in forest remnants of an ecotonal Atlantic Forest-Cerrado area from southeastern Brazil

“…The high richness of bats, compared with others studies (e.g., Muylaret et al, 2014;Novaes et al, 2014c;Souza et al, 2015) may be explained by two non-mutually exclusive hypotheses: (1) high diversity of bats in natural environments, which can represent up to 50% of species in the mammal community of a region (Timm, 1994;Hutterer et al, 1995;Modesto et al, 2008); and (2) differential sampling effort for different groups, once the bats have been a major focus of field research over recent years. In the present study, the most abundant bat species were S. lilium and A. lituratus, which together account for more than half of all captures.…”

“…In the present study, the most abundant bat species were S. lilium and A. lituratus, which together account for more than half of all captures. Similarly, a high abundance of these species has been found in other areas of the Atlantic Forest and Cerrado (e.g., Muylaret et al, 2014;Souza et al, 2015), particularly in perturbed areas.…”

Enhancing sampling design in mist-net bat surveys by accounting for sample size optimization

“…Sampling was conducted between 2008 and 2012, and encompassed dense evergreen forests at the continental boundaries between the Serra do Mar and seasonal semi-deciduous forests, which represent typical low to mid elevation forests of coastal regions of southeastern Brazil. Data from these four bat communities represent 59 sampling nights and 1,877 individuals captured [28, 29]. …”

Expansion of the southern limit of Vampyrodes caraccioli Thomas, 1889 (Chiroptera, Phyllostomidae) and first record for Santa Catarina state, southern Brazil

“…This species has been recorded for the Atlantic Forest biome in the northeast (Faria 2006), southeast (Lourenço et al 2010, Souza et al 2015 and recently in the south region of Brazil, in Paraná state, with this being the austral limit known for this species (Carvalho et al 2014). Studies about the fauna of bats for the state of Santa Catarina had not listed V. caraccioli (Cherem et al 2004, Passos et al 2010) and this study also represents the first record of this species in the state of Santa Catarina.…”

“…Vampyrodes. caraccioli is usually reported with small abundance in inventories (e.g Kalko and Handley 2001, Martins et al 2006, Souza et al 2015, compromising further information about its biology and ecology. The present note aims to report the expansion of the Southern limit distribution of Vampyrodes caraccioli and the first record for Santa Catarina state in southern Brazil.…”
