| phyllostomid bat microbiome composition is associated to host phylogeny and feeding strategies. | the members of the phyllostomidae, the new-world leaf-nosed family of bats, show a remarkable evolutionary diversification of dietary strategies including insectivory, as the ancestral trait, followed by appearance of carnivory and plant-based diets such as nectarivory and frugivory. here we explore the microbiome composition of different feeding specialists: insectivore macrotus waterhousii, sanguivore desmodus rotundus, nectarivores leptonycteris yerbabuenae and glossophaga soricina, and frugi ... | 2015 | 26042099 |
| rapidly evolving repetitive dnas in a conservative genome: a test of factors that affect chromosomal evolution. | the hypothesis that tandemly repeated dna sequences may facilitate chromosomal rearrangements was tested by comparing a conservatively evolving karyotype of a bat species (macrotus waterhousii) with data published for a rapidly evolving karyotype of an equid species (equus zebra). empirical data generated from the phylogenetic screening of rapidly evolving repetitive dnas from approximately 0.1% of the m. waterhousii genome showed only one sequence that was repetitive in m. waterhousii but low i ... | 1994 | 7981939 |
| [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 |
| exploring demographic, physical, and historical explanations for the genetic structure of two lineages of greater antillean bats. | observed patterns of genetic structure result from the interactions of demographic, physical, and historical influences on gene flow. the particular strength of various factors in governing gene flow, however, may differ between species in biologically relevant ways. we investigated the role of demographic factors (population size and sex-biased dispersal) and physical features (geographic distance, island size and climatological winds) on patterns of genetic structure and gene flow for two line ... | 2011 | 21445291 |
| characterization of polymorphic microsatellite loci for two species of phyllostomid bats from the greater antilles (erophylla sezekorni and macrotus waterhousii). | we developed 12 polymorphic microsatellite loci for the buffy flower bat (erophylla sezekorni) and 10 loci for waterhouse's big-eared bat (macrotus waterhousii). in e. sezekorni, we tested 65 individuals from three islands, cuba, exuma, and abaco. mean number of alleles per locus was 10.7 (range 5-20). in m. waterhousii, we tested 39 individuals from one island, exuma. mean number of alleles per locus was 6.9 (range 4-13). we will use these markers to study the phylogeography and mating system o ... | 2008 | 21585843 |
| a new species of torrestrongylus (trichostrongylidae, anoplostrongylinae) from macrotus waterhousii (chiroptera: phyllostomidae) in central mexico. | a new species of nematode, torrestrongylus tetradorsalis n. sp., is described herein, based on specimens recovered from the small intestine of the leaf-nosed bat, macrotus waterhousii, from the biosphere reserve "sierra de huautla" in the state of morelos, mexico. the new species is included in torrestrongylus because it features a bursa of the type 3 - 2, a divided cephalic vesicle with an anterior half in the shape of an umbrella, and a posterior widened half. the new species can be distinguis ... | 2015 | 26514594 |
| resource partitioning by insectivorous bats in jamaica. | in this investigation, we use variation in wing morphology, echolocation behaviour, patterns of habitat use and molecular diet analysis to demonstrate that six species of sympatric insectivorous bats in jamaica show significant differences that could explain resource partitioning among the species. high-intensity echolocating species that used shorter, broadband signals and had shorter, broader wings (pteronotus macleayii, pteronotus quadridens, mormoops blainvillii) foraged most in edge habitat ... | 2014 | 25187923 |
| narrow sound pressure level tuning in the auditory cortex of the bats molossus molossus and macrotus waterhousii. | in the auditory system, tuning to sound level appears in the form of non-monotonic response-level functions that depict the response of a neuron to changing sound levels. neurons with non-monotonic response-level functions respond best to a particular sound pressure level (defined as "best level" or level evoking the maximum response). we performed a comparative study on the location and basic functional organization of the auditory cortex in the gleaning bat, macrotus waterhousii, and the aeria ... | 2014 | 24269749 |
| dna synapomorphies for a variety of taxonomic levels from a cosmid library from the new world bat macrotus waterhousii. | an effective method yielding taxon-specific markers from the genome of a single individual would be valuable for many types of scientific investigations, including systematic, forensic, conservation, and evolutionary studies. we explored the use of cosmid libraries, with insert sizes averaging 35 kb, to streamline the process of locating sequences of dna that can serve as taxonomic markers from the specific to the ordinal levels. by screening approximately 2.6% of the leaf-nosed bat (macrotus wa ... | 1997 | 11975334 |
| how bats achieve a small c-value: frequency of repetitive dna in macrotus. | bats possess a genome approximately 50-87% the size of other eutherian mammals. we document that the events that have achieved or maintained a small genome size in the mexican leaf-nosed bat macrotus waterhousii have resulted in a lower copy number of interspersed and tandemly repetitive elements. these conclusions are based on examination of 1726 randomly chosen recombinant cosmids, with an average insert size of 35.7 kb and representing 2.6% of the haploid genome of m. waterhousii. probes repr ... | 1995 | 8589520 |
| reproductive biology of the male leaf-nosed bat, macrotus waterhousii in southwestern united states. | the reproductive biology of the bat macrotus waterhousii was investigated anatomically and physiologically several times monthly throughout the year. the male spermatogenic cycle is initiated in june; sperm are available in august. testicular hypertrophy is accompanied by increased levels of testicular ascorbic acid and circulating plasma testosterone. sperm are present in the seminiferous tubules and later the epididymides from august to early december. regression in testicular size begins in l ... | 1976 | 943969 |

| genomic consequences of dietary diversification and parallel evolution due to nectarivory in leaf-nosed bats. | the new world leaf-nosed bats (phyllostomids) exhibit a diverse spectrum of feeding habits and innovations in their nutrient acquisition and foraging mechanisms. however, the genomic signatures associated with their distinct diets are unknown. | 2020 | 32510151 |
| interspecific comparisons of immunohistochemical localization of retinal neurotransmitters in four species of bats. | four ecologically distinctive neotropical bat species of the family phyllostomidae were collected and their retinae surveyed immunohistochemically for the presence of neurotransmitter candidates: glucagon, somatostatin, vasoactive intestinal peptide, substance p (sp), methionine enkephalin, serotonin (5-ht) and two enzymes, glutamic acid decarboxylase (gad) and tyrosine hydroxylase (toh). in all four species immunoreactivity (ir) to gad, toh and sp was found. gad-ir and sp-ir showed little inter ... | 1987 | 2444311 |
