consumption of leaves by platyrrhinus lineatus (chiroptera, stenodermatinae): are these bats primarily frugivorous or broadly phytophagous?until now, the consumption of leaves by bats has been considered rare or sporadic, even among the herbivorous families pteropodidae and phyllostomidae. among the phyllostomids there are reports of folivory in the genera artibeus and platyrrhinus, based on opportunistic observations. here, we conducted behavioural sampling using camera-trapping in the roost of a colony of platyrrhinus lineatus already known to consume leaves during the dry and wet seasons, in order to investigate the frequency of ...201728065498
ultrastructural characteristics of spermatogenesis in pallas's mastiff bat, molossus molossus (chiroptera: molossidae).despite the large number of species, their wide distribution, and unique reproductive characteristics, neotropical bats have been poorly studied, and important aspects of the reproduction of these animals have not been elucidated. we made an ultrastructural analysis of spermatogenesis in molossus molossus (molossidae). the process of spermatogonial differentiation is similar to that found in other bats and is also relatively similar to that of primates, with three main spermatogonia types: a(d), ...201222253210
atlantic bats: a dataset of bat communities from the atlantic forests of south america.bats are the second most diverse mammal order and they provide vital ecosystem functions (e.g., pollination, seed dispersal, and nutrient flux in caves) and services (e.g., crop pest suppression). bats are also important vectors of infectious diseases, harboring more than 100 different virus types. in the present study, we compiled information on bat communities from the atlantic forests of south america, a species-rich biome that are highly threatened by habitat loss and fragmentation. atlantic ...201728875505
