| nutrition or detoxification: why bats visit mineral licks of the amazonian rainforest. | many animals in the tropics of africa, asia and south america regularly visit so-called salt or mineral licks to consume clay or drink clay-saturated water. whether this behavior is used to supplement diets with locally limited nutrients or to buffer the effects of toxic secondary plant compounds remains unclear. in the amazonian rainforest, pregnant and lactating bats are frequently observed and captured at mineral licks. we measured the nitrogen isotope ratio in wing tissue of omnivorous short ... | 2008 | 18431492 |
| species richness and abundance of bats in fragments of the stational semidecidual forest, upper paraná river, southern brazil. | the upper paraná river floodplain is inserted in a region of the mata atlântica biome, which is a critical area to preserve. due to the scarcity of researches about the chiropterofauna in this region, the present study investigated species richness and abundance of bats in remnants from the stational semidecidual forest of the upper paraná river, southern brazil. samplings were taken every month, from january to december 2006, using 32 mist nets with 8.0 x 2.5 m, resulting in 640 m2/h and totali ... | 2009 | 19738978 |
| cytotaxonomy of the subgenus artibeus (phyllostomidae, chiroptera) by characterization of species-specific markers. | the genus artibeus represents a highly diverse group of bats from the neotropical region, with four large species occurring in brazil. in this paper, a comparative cytogenetic study was carried out on the species artibeus obscurus schinz, 1821, artibeus fimbriatus gray, 1838, artibeus lituratus olfers, 1818 and artibeus planirostris spix, 1823 that live sympatrically in the northeast of brazil, through c-banding, silver staining and dna-specific fluorochromes (cma3 and dapi). all the species had ... | 2012 | 24260649 |
| phylogeography of the dark fruit-eating bat artibeus obscurus in the brazilian amazon. | artibeus obscurus (mammalia: chiroptera) is endemic to south america, being found in at least 18 brazilian states. recent studies revealed that different populations of this genus present distinct phylogeographic patterns; however, very little is known on the population genetics structure of a. obscurus in the amazon rainforest. here, using a fragment (1010bp) of the mitochondrial gene cytochrome b from 87 samples, we investigated patterns of genetic divergence among populations of a. obscurus f ... | 2013 | 24127548 |
| a phylogenetic analysis using multidirectional chromosome painting of three species (uroderma magnirostrum, u. bilobatum and artibeus obscurus) of subfamily stenodermatinae (chiroptera-phyllostomidae). | the species of genera uroderma and artibeus are medium-sized bats belonging to the family phyllostomidae and subfamily stenodermatinae (mammalia, chiroptera) from south america. they have a wide distribution in the neotropical region, with two currently recognized species in uroderma and approximately 20 species in artibeus. these two genera have different rates of chromosome evolution, with artibeus probably having retained the ancestral karyotype for the subfamily. we used whole chromosome pai ... | 2013 | 23775139 |
| megamitochondria in the serous acinar cells of the submandibular gland of the neotropical fruit bat, artibeus obscurus. | as part of a continuing investigation of the comparative ultrastructure of chiropteran salivary glands, we examined the submandibular glands of eight species of neotropical fruit bats in the genus artibeus. we previously described secretory granules of unusual substructure in the seromucous demilunar cells of this organ in some species in this genus. in the present study, we turned our attention to the serous acinar cells in the same glands. | 1997 | 9143663 |
| 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 ... | 2017 | 28875505 |
| molecular detection of bartonella spp. and rickettsia spp. in bat ectoparasites in brazil. | the family streblidae comprises a monophyletic group of hippoboscoidea, hematophagous dipterans that parasitize bats. bartonella spp. and rickettsia spp. have been reported in bats sampled in europe, africa, asia, north, central and south america. however, there are few reports on the bartonella and rickettsia bacteria infecting hippoboscoidea flies and mites. while spinturnicidae mites are ectoparasites found only in bats, those belonging to the family macronyssidae comprise mites that also par ... | 2018 | 29870549 |
| second-growth and small forest clearings have little effect on the temporal activity patterns of amazonian phyllostomid bats. | secondary forests and human-made forest gaps are conspicuous features of tropical landscapes. yet, behavioral responses to these aspects of anthropogenically modified forests remain poorly investigated. here, we analyze the effects of small human-made clearings and secondary forests on tropical bats by examining the guild- and species-level activity patterns of phyllostomids sampled in the central amazon, brazil. specifically, we contrast the temporal activity patterns and degree of temporal ove ... | 2020 | 32440274 |
