| absent or low rate of adult neurogenesis in the hippocampus of bats (chiroptera). | bats are the only flying mammals and have well developed navigation abilities for 3d-space. even bats with comparatively small home ranges cover much larger territories than rodents, and long-distance migration by some species is unique among small mammals. adult proliferation of neurons, i.e., adult neurogenesis, in the dentate gyrus of rodents is thought to play an important role in spatial memory and learning, as indicated by lesion studies and recordings of neurons active during spatial beha ... | 2007 | 17520014 |
| antibodies against duvenhage virus in insectivorous bats in swaziland. | several rabies-related lyssaviruses have been associated with bat species in southern africa, the rarest of these being duvenhage virus (duvv), for which only five isolations have been made over five decades. three of these were from human fatalities, and it is not known which bat species acts as reservoir. in studying a population of nycteris thebaica in the kingdom of swaziland, a landlocked country bordering mozambique and south africa, we found evidence of the circulation of a lyssavirus. vi ... | 2013 | 24502729 |
| the importance of acacia trees for insectivorous bats and arthropods in the arava desert. | anthropogenic habitat modification often has a profound negative impact on the flora and fauna of an ecosystem. in parts of the middle east, ephemeral rivers (wadis) are characterised by stands of acacia trees. green, flourishing assemblages of these trees are in decline in several countries, most likely due to human-induced water stress and habitat changes. we examined the importance of healthy acacia stands for bats and their arthropod prey in comparison to other natural and artificial habitat ... | 2013 | 23441145 |
| support for the allotonic frequency hypothesis in an insectivorous bat community. | the allotonic frequency hypothesis proposes that certain insectivorous bat species can prey upon moths that can hear bat echolocation calls by using echolocation frequencies outside the sensitivity range of moth ears. the hypothesis predicts that the peak frequencies of bat echolocation calls are correlated with the incidence of moths in the diets of these bats. the aim of this study was to test this prediction on a bat community dominated by bats using low duty cycle echolocation calls, i.e. ae ... | 2003 | 12647192 |
| on a new trematode, prohemistomum azimi n. sp. (trematoda: cyathocotylidae) from the egyptian slit-faced bat. | prohemistomum azimi n. sp. is described from one out of four egyptian slit-faced bats, nycteris thebaica geffroy, 1910 captured from giza, egypt. the new species is compared with other related species of the genus and its specific diagnosis is outlined. the new species is the first record of the genus prohemistomum odhner, 1913 from chiroptera. | 1977 | 595795 |
| interspecific variation in thermoregulation among three sympatric bats inhabiting a hot, semi-arid environment. | bats in hot roosts experience some of the most thermally challenging environments of any endotherms, but little is known about how heat tolerance and evaporative cooling capacity vary among species. we investigated thermoregulation in three sympatric species (nycteris thebaica, taphozous mauritianus and sauromys petrophilus) in a hot, semi-arid environment by measuring body temperature (t(b)), metabolic rate and evaporative water loss (ewl) at air temperatures (t(a)) of 10-42 °c. s. petrophilus ... | 2012 | 22740044 |
| placentation in the egyptian slit-faced bat nycteris thebaica (chiroptera: nycteridae). | bats are a highly successful, widely distributed group, with considerable variation in placental structure. the egyptian slit-faced bat nycteris thebaica is a member of one of the few families with previously undescribed placentation. it was found that, although the interhemal type of the nycteris placenta is endotheliochorial with a single layer of cytotrophoblast, the arborizing pattern of the maternal vessels and especially the extraordinary major placental artery differs from the placenta of ... | 2009 | 19674786 |
| molecular phylogenetics of slit-faced bats (chiroptera: nycteridae) reveal deeply divergent african lineages. | the bat family nycteridae contains only the genus nycteris, which comprises 13 currently recognized species from africa and the arabian peninsula, one species from madagascar, and two species restricted to malaysia and indonesia in south-east asia. we investigated genetic variation, clade membership, and phylogenetic relationships in nycteridae with broad sampling across africa for most clades. we sequenced mitochondrial cytochrome b (cytb) and four independent nuclear introns (2,166 bp) from 25 ... | 2019 | 31894177 |
| a comparative morphological and histological study of the gastrointestinal tract of four insectivorous bat species: asellia tridens, chaerephon pumilus, nycteris thebaica, rhinopoma hardwickii. | various studies address the morphology of the gastrointestinal tracts (gits) of insectivorous bat species. however, detailed morphometric studies including mucin histochemistry are scarce. this study compares various git measurements as well as the quantification of intestinal mucin secreting cells in four insectivorous bat species representing four different families of chiroptera. alcian blue/periodic acid schiff's stain was used to differentiate between acid and neutral mucin-secreting cells ... | 2019 | 31116472 |
