Mammalia, Chiroptera, Vespertilionidae, Myotis albescens: new occurrence site in the state of Rio Grande do Sul, Brazil

Abstract

None.

Mammalia, Chiroptera, Rio Grande, state of Rio Grande do Sul, Brazil

“…A single individual of Eptesicus brasiliensis (Desmarest, 1819) was captured in mist net over sandy riparian wood, while another one was found dead in an attic with ceramic roof in urban area. A single individual of Myotis albescens was captured in mist net over coastal stream with shrub/ herbaceous riparian vegetation, which was previously reported in a preliminary phase of this study (Quintela et al 2008). Two specimens of Myotis nigricans (Schinz, 1821) were found dead in a bridge over a coastal stream with sandy riparian wood, while another specimen was captured in mist net in a marsh area.…”

Families and species of bats recorded in the municipality of Rio Grande, Rio Grande do Sul State, being: a = field sampling, b = IB-FURG collection, c = previous records (Fabian et al 1999;Pacheco and Freitas 2003;Quintela et al 2008); MN = number of specimens captured in mist nets, DR = number of specimens captured in diurnal roosts, DS = number of dead specimens found in habitats, IB = number of individuals stored in IB-FURG collection; Hg = herbaceous grassland, Rw = stream with sandy riparian wood, Rh = stream with herbaceous/arbustive riparian vegetation, Sd = shrub dune, Sg = shrub grassland, Sw = swamp, Ua = urban area, ? = no data available.…”

“…In the southern portion of the geomorphological unit of coastal plain, considered as part of an area of extreme biological importance for mammal conservation in Atlantic Forest and Campos Sulinos biomes (Conservation International do Brasil et al 2000), little effort has been made for the understanding of the richness and ecological features of mammalian fauna assemblages. Published data on chiropteran occurrence in this important area have been restricted to punctual records of Desmodus rotundus (É. Geoffroy, 1818) (Fabián et al 1999), Nyctinomops laticaudatus (É. Geoffroy, 1805) (Pacheco and Freitas 2003) and Myotis albescens (É. Geoffroy, 1806) (Quintela et al 2008). Aiming to contribute to information gathering about the chiropteran fauna in this region, we present a list of bat species recorded in the municipality of Rio Grande, southern Rio Grande do Sul coastal plain, besides data on habitat occupancy.…”

Legal Atlantic Forest (Mata Atlântica Legal): integrating biogeography to public policies towards the conservation of the biodiversity hotspot

“…Reptiles from southern RS are predominantly Pampean (QUINTELA et al, 2006), as are bats, with the influence of typical species from open formations (QUINTELA, et al, 2008). Above all, studies of biotic changes along the Holocene, over the last 10,000 years, indicate a gradual dynamic of expansion and shrinkage of rainforests, dry forests, and savannas in this region, and the previous presence of marsupials typical from areas of the southeast Atlantic Forest and dry forests of central Brazil (HADLER et al, 2009).…”

Morcegos de Frederico Westphalen, Rio Grande do Sul, Brasil (Mammalia: Chiroptera): riqueza e utilização de abrigos

“…Entre outubro de 2004 e junho de 2008, foram realizadas amostragens de quirópteros em onze áreas no município (Apêndice I). Três destas áreas receberam esforços sistematizados, onde cada uma Myotis albescens (E. Geoffroy, 1806) -Listada como espécie com "dados insuficientes" por Pacheco & Freitas (2003), teve recentemente reavaliada sua distribuição geográfica no Rio Grande do Sul, estando presente em oito localidades (Quintela et al 2008). Em Frederico Westphalen a espécie foi capturada nas áreas 1 e 3.…”
