| Chrotopterus auritus (Peters, 1856) (Phyllostomidae, Chiroptera) é a única espécie carnívora de morcego registrada para o estado do Rio Grande do Sul. Neste trabalho a dieta e o uso de abrigos diurnos foram estudados. Sete cavernas foram monitoradas, a cada quinze dias, no período de maio/2002 a abril/2003, nos municípios de Machadinho e Barracáo, Rio Grande do Sul, Brasil. A dieta foi estudada por meio da análise das fezes (n=67) e restos alimentares (n=63) coletados quinzenalmente em cada abrigo. Mamíferos, aves e artrópodes constituíram a base alimentar de C. auritus. O resultado do exame das fezes não evidencia a preferência por presas como mamíferos, aves ou artrópodes, pois não há diferença significativa na freqüéncia de ocorréncia dos mesmos. O... |

| A study has been made on the geographical distribution and comparative external and cranial morphological analysis of Artibeus lituratus Olfers, 1818 and Artibeus fimbriatus Gray, 1838 (Chiroptera, Phyllostomidae) in the state of Rio Grande do Sul, Brazil. A. lituratus and A. fimbriatus were found to be sympatric in the state north to the "Planície Costeira", in the "Depressão Central", in the hillsides of "Serra Geral", and in the northern region of the state, areas previously covered by forests. The southernmost point for Artibeus Leach, 1821 distribution is 30º South, and A. lituratus and A. fimbriatus are the two species found more to the south. The two species studied do not show sexual dimorphism as to external characteristics. Cranial measurements... |

| Abstract Bats of the Phyllostomidae family exhibit different reproductive patterns in Neotropical regions and the strategy adopted depends on the regional climate. Here we studied the reproductive biology of Artibeus fimbriatus at the southern limit of their distribution in Brazil. This region has no rainy season, and the climate is characterized by high temperatures and variable photoperiods. We examined 129 A. fimbriatus females over several months, and used histological procedures where necessary in order to determine whether bats were pregnant. Females exhibited a long reproductive period and were pregnant from June until February. The reproduction events were found to be dependent on the photoperiod, but independent of annual accumulated... |
