RESUMO(*) Museu Paraense Emilio Goeldi, Belem, PA. INTRODUCAOOs dois determinantes ecologicos mais importantes da estrutura social dos morcegos parecem ser abrigos adequados e suprimento suficiente de alimento (Bradbury,1977). Dwyer notaram que os morcegos que utilizam cavernas ou estruturas construfdas pelo homem, ten dem a ser mais gregarios ao menos, interespecificamente, e quando colon ias grandes ocor rem, ha uma marcada tendencia para segregacao sazonal dos sexos. A coabitacao entre varias especies de morcegos que utilizam abrigos internos (protegidos) e bastante comum .Muitas vezes, varias especies parti 1 ham 0 abrigo em contato corporal uma com as outras (Goodwin & Greenhall, I960 -Bradbury (1977) cita, como regra geral, que estas associa_ coes sao casuais, com cada especie ocupando uma regilo particular do abrigo e com 0

Bats (Mammalia: Chiroptera) from Guarulhos, state of São Paulo, Brazil

“…All four species have been observed cohabiting caves of the valley of the Rio Ribeira, SP (Trajano 1985), and the first three were observed in cohabitation in caves in the Federal District, Central-Western Brazil (Bredt et al 1999). Marques (1985) had recorded C. perspicillata and A. caudifer cohabiting manholes in Manaus, AM, northern Brazil.…”

“…Seven species (D. rotundus, C. perspicillata, G. soricina, A. caudifer, S. lilium, A. lituratus, and A. fimbriatus) were captured in the net set in front of the tunnel's entrance. We did not check if these species were roosting inside the tunnel, but in the literature only D. rotundus and C. perspicillata were frequently observed harboring in this type of day roost (Marques 1985;Gomes and Uieda 2004;Oliveira et al 2009). …”

The bats of Argentina

“…It was first reported in Argentina by Fomes and Massoia (1969). Roosts include bridges, culverts, tree holes, roofs of ru¬ ral dwellings, caves, and crevices (e.g., Marques, 1985). Willig (1983) found it in buildings with Glossophaga soricina.…”

Trachops cirrhosus

“…Trachops cirrhosus roosts mainly in trees and hollow logs (Armstrong 1969;Goodwin and Greenhall 1961;Handley 1976;Krull and Kalko 1994;Kunz 1982;Patterson 1992), but has roosted in caves (Jones 1966), culverts (Handley 1976;Starrett and Casebeer 1968), buildings (Tuttle 1976), and an abandoned railroad tunnel (Starrett and Casebeer 1968 (Goodwin and Greenhall1961;Marques 1985;Ruschi 1953). T. cirrhosus roosts in groups of up to 50 individuals (Hall and Dalquest 1963), and both sexes may roost together (Nowak 1999).…”
