| intestinal disaccharidases in five species of phyllostomoid bats. | 1. intestinal disaccharidases were studied in nectarivorous (leptonycteris curasoae and glossophaga soricina), frugivorous (artibeus jamaicensis and sturnira lilium), and insectivorous (pteronotus personatus) adult bats. 2. adult bats lacked measurable lactase activity. with the exception of trehalase activity, which was present only in p. personatus, nectar- and fruit-eating bats exhibited higher disaccharidase activities standardized by intestinal nominal area than insect-eating p. personatus. ... | 1992 | 1451428 |
| doppler-shift compensation behavior by wagner's mustached bat, pteronotus personatus. | doppler-shift compensation behavior (dsc) is a highly specialized vocal response displayed by bats that emit pulses with a prominent constant frequency (cf) component and adjust the frequency of their cf component to compensate for flight-speed induced doppler shifts in the frequency of the returning echoes. dsc has only been observed in one member of the neotropical mormoopidae, a family of bats that use pulses with prominent cf components, leading researchers to suspect that dsc is a uniquely ... | 2008 | 18537384 |
| influence of feeding habits in the endocrine pancreas of insectivore bat pteronotus personatus and nectarivore bat anoura geoffroyi: a comparative stereological and immunohistochemical study. | pteronotus personatus as an insectivore bat and has a diet that consists of a high protein diet, whereas the diet of anoura geoffroyi, a predominantly nectarivore bat, is rich in simple sugars like sucrose, glucose and fructose. considering that diet influences the activation of different pathways, which may influence morphological adaptations in the gastrointestinal system, the aim of this study was to compare the morphology of the endocrine pancreas in p. personatus and a. geoffroyi. for this, ... | 2017 | 28109546 |
| [population dynamics, roost selection and reproductive patterns of some cave bats from western of mexico]. | population dynamics, roost selection and reproductive patterns of some cave bats from western of mexico. almost half of bat species that occur in mexico use caves as permanent or temporal roosts. however, the ecological studies about cave bat communities are scarce. in this work we studied the population dynamics, roost selection and reproductive patterns of some bats present in el salitre cave, colima, mexico. we carried out monthly samplings between august 2003-march 2005 using a harp trap for ... | 2012 | 23025105 |
| a new spirurid (nematoda) parasite from mormoopid bats in mexico. | a new nematode species, spirura mexicana n. sp., is described from specimens recovered from the esophageal mucosa of the parnell's mustached bat pteronotus parnellii , davy's naked-backed bat pteronotus davyi, wagner's mustached bat pteronotus personatus, and the ghost-faced bat mormoops megalophylla in the state of morelos, mexico. this nematode is characterized by having a relatively short prostoma, 5-6 pairs of caudal papillae, and a smooth distal end of the tail in females. this is the first ... | 2012 | 22509820 |
| helminth fauna associated with three neotropical bat species (chiroptera: mormoopidae) in veracruz, mexico. | bats are recognized as potential hosts of pathogens exploiting the food chain to reach them as definitive hosts. however, very little is known about their endoparasites, especially for neotropical bats. in this study, we assessed the helminth fauna associated with 3 insectivorous bat species roosting in the same single hot cave in central veracruz, mexico: the ghost-faced bat (mormoops megalophylla), the naked-backed bat (pteronotus davyi) and wagner's mustached bat (pteronotus personatus). duri ... | 2017 | 28420310 |
| the bat fauna of the kararaô and kararaô novo caves in the area under the influence of the belo monte hydroelectric dam, in pará, brazil. | brazil's large territory displays significant richness in caves with about 12 thousand caves already recorded. nevertheless, studies on bats in these environments are extremely scarce and fragmented. this study characterized the chiropteran fauna from two sandstone caves under the influence of the belo monte hydroelectric dam (belo monte uhe) in pará, brazil. the kararaô and kararaô novo caves are located on the same ridge, 250 m apart. three expeditions were carried out in 2013 and 2014, with a ... | 2015 | 26691088 |
| isolation and characterization of microsatellite marker loci in the wagner's mustached bat pteronotus psilotis (chiroptera: mormoopidae) and crossamplification in other related species. | pteronotus psilotis, a mormoopid bat, is an insectivorous, gregarious and strict cave-dwelling species that is found areas between the sea level and an elevation of about 1000 masl. this species is present in diverse habitats ranging from rain forest to dry deciduous forest. nine microsatellite loci were developed for wagner's mustached bat, pteronotus psilotis using the next-generation sequencing approach, and their utility for population genetics studies was assessed. all loci were polymorphic ... | 2018 | 30555067 |
| new records and phylogenetic position of ornithodoros knoxjonesi (ixodida: argasidae). | larvae of ornithodoros knoxjonesi collected at five localities in three countries were studied using morphological and molecular methods to confirm this species' taxonomic validity. the larva of o. knoxjonesi is characterized as having 14 pairs of dorsal setae, eight pairs of ventral setae, plus a posteromedian seta; an elongate dorsal plate, tapered anteriorly; and a hypostome that is narrower near its midlength, with posteriorly projecting denticles. although the larvae of o. knoxjonesi and or ... | 2020 | 32723648 |
| mitochondrial genome of pteronotus personatus (chiroptera: mormoopidae): comparison with selected bats and phylogenetic considerations. | we described the complete mitochondrial genome (mitogenome) of the wagner's mustached bat, pteronotus personatus, a species belonging to the family mormoopidae, and compared it with other published mitogenomes of bats (chiroptera). the mitogenome of p. personatus was 16,570 bp long and contained a typically conserved structure including 13 protein-coding genes, 22 transfer rna genes, two ribosomal rna genes, and one control region (d-loop). most of the genes were encoded on the h-strand, except ... | 2017 | 27995348 |
| dietary overlap and seasonality in three species of mormoopid bats from a tropical dry forest. | competing hypotheses explaining species' use of resources have been advanced. resource limitations in habitat and/or food are factors that affect assemblages of species. these limitations could drive the evolution of morphological and/or behavioural specialization, permitting the coexistence of closely related species through resource partitioning and niche differentiation. alternatively, when resources are unlimited, fluctuations in resources availability will cause concomitant shifts in resour ... | 2015 | 26369564 |
