Morcegos capturados no municĂpio de Belo Horizonte, 1999-2003 Bats found in the city of Belo Horizonte, MG, 1999-2003
Entre os anos de 1999 e 2001, realizaram-se 18 capturas de morcegos em Belo Horizonte, sendo uma na estação seca e uma na estação chuvosa em cada regional administrativa. Foram capturados 316 exemplares, com predominĂąncia de Artibeus lituratus (Olfers, 1818), 55,1%, Platyrrhinus lineatus (Geoffroy, 1810), 24,4% e Glossophaga soricina (Pallas, 1766), 10,1%, alĂ©m de Sturnira lilium (Geoffroy, 1810), Phyllostomus discolor (Wagner, 1843), Carollia perspicillata (Linnaeus, 1758), Myotis nigricans (Schinz, 1821) e Anoura caudifer (Geoffroy, 1818), totalizando oito espĂ©cies, pertencentes Ă s famĂlias Phyllostomidae e Vespertilionidae. Observou-se concentração de partos prĂłximos Ă estação chuvosa, coincidindo com a maior disponibilidade de alimento para os perĂodos de prenhez e lactação. Partos esporĂĄdicos ocorreram durante todo o ano. Entre 2002 e 2003, foi feita uma busca em diversos tipos de abrigos nas mesmas regionais. Os abrigos foram registrados, e as espĂ©cies encontradas foram somadas Ă s jĂĄ observadas na primeira parte deste estudo, bem como Ă s citadas em diversas fontes bibliogrĂĄficas e disponĂveis em coleçÔes acadĂȘmicas, gerando um relato atualizado das espĂ©cies de morcegos jĂĄ encontrados no municĂpio.<br>A total of 316 bats were trapped using mist nets during 18 nights at nine strategic locations in Belo Horizonte between 1999 and 2001. The most predominant species were Artibeus lituratus (Olfers, 1818), 55.1%, Platyrrhinus lineatus (Geoffroy, 1810), 24.4%, and Glossophaga soricina (Pallas, 1766), 10.1%. Other trapped species were: Sturnira lilium (Geoffroy, 1810), Phyllostomus discolor (Wagner, 1843), Carollia perspicillata (Linnaeus, 1758), Myotis nigricans (Schinz, 1821) and Anoura caudifer (Geoffroy, 1818), resulting in a total of eight species belonging the families Phyllostomidae and Vespertilionidae. All species bred predominantly during the wet season, probably because of the need for food availability to support energetic demands during pregnancy and lactation. However, all species bred at other times of the year as well. An updated list of bat species found in Belo Horizonte was prepared which included those observed in the first part of this study, those cited in scientific papers and academic collections and those recorded in additional observations during 2002 and 2003
Partição de recursos alimentares entre quatro espĂ©cies de morcegos frugĂvoros (Chiroptera, Phyllostomidae)
Dados ecolĂłgicos dos quirĂłpteros da Reserva Volta Velha, ItapoĂĄ, Santa Catarina, Brasil Ecological data of Chiroptera from Reserva Volta Velha, ItapoĂĄ, Santa Cantarina, Brazil
<abstract language="eng">A study on the ecology of Chiroptera was made at the Reserve of Volta Velha on the Northern coast of Santa Catarina. This study aimed at knowing the frequency of the individuals colleeted in each season, part of their feeding diet and their time of activity as well as their breeding activity. The investigation was carried out from March, 1990 to February, 1991 by means of periodical captures which ocurred during four days each month totalizing 144 hours of net use. One hundred and thirty-five individuals belonging to 15 different species were caught. Sturnira lilium (Geoffroy, 1810), Artibeus lituratus (Olfers, 1818) and Myotis nigricans (Schinz, 1821) were captured in the highest number throughout the seasons of the year. Fruit-eating bats confirm their feeding preference for Cecropiaceae, Solanaceae. Myrtaceae and Piperaceae. The births occurred mostly in seasons other than the dry. Around 1:15 hours after sunset was the time when the highest numher of individuals were collected in the nets
