the karyotype and 5s rrna genes from spanish individuals of the bat species rhinolophus hipposideros (rhinolophidae; chiroptera).the karyotype of individuals of the species rhinolophus hipposideros from spain present a chromosome number of 2n = 54 (nfa = 62). the described karyotype for these specimens is very similar to another previously described in individual from bulgaria. however, the presence of one additional pair of autosomal acrocentric chromosomes in the bulgarian karyotype and the differences in x chromosome morphology indicated that we have described a new karyotype variant in this species. in addition, we ha ...200818066670
street lighting disturbs commuting bats.anthropogenic disturbance is a major cause of worldwide declines in biodiversity. understanding the implications of this disturbance for species and populations is crucial for conservation biologists wishing to mitigate negative effects. anthropogenic light pollution is an increasing global problem, affecting ecological interactions across a range of taxa and impacting negatively upon critical animal behaviors including foraging, reproduction, and communication (for review see). almost all bats ...200919540116
phylogeography and postglacial recolonization of europe by rhinolophus hipposideros: evidence from multiple genetic markers.the demographic history of rhinolophus hipposideros (lesser horseshoe bat) was reconstructed across its european, north african and middle-eastern distribution prior to, during and following the most recent glaciations by generating and analysing a multimarker data set. this data set consisted of an x-linked nuclear intron (bgn; 543 bp), mitochondrial dna (cytb-trna-control region; 1630 bp) and eight variable microsatellite loci for up to 373 individuals from 86 localities. using this data set o ...201323889545
the patterns of seasonal activity of ixodes vespertilionis (acari: ixodidae) on rhinolophus hipposideros in nursery colonies.the aim of this study was to describe the dynamics of the long-legged bat tick ixodes vespertilionis infestation on the lesser horseshoe bat rhinolophus hipposideros in 2 nursery colonies roosting in attics. out of a total of 810 lesser horseshoe bats examined, 217 (26.8%) were found to be infested with a total of 464 i. vespertilionis individuals. the developmental stage most frequently found was the larva, followed by the nymph, and the adult female. bats were significantly more frequently inf ...201424252260
first amplification of eimeria hessei dna from the lesser horseshoe bat (rhinolophus hipposideros) and its phylogenetic relationships with eimeria species from other bats and rodents.although coccidian parasites of the genus eimeria are among the best-documented parasites in bats, few eimeria species found in bats have been characterised using molecular tools, and none of the characterised species are found in european countries. phylogenetic relationships of eimeria species that parasitise bats and rodents can be related to the morphology of oocysts, independently from host range, suggesting that these species are derived from common ancestors. in the present study, we isol ...201424594259
wing membrane biopsies for bat cytogenetics: finding of 2n = 54 in irish rhinolophushipposideros (rhinolophidae, chiroptera, mammalia) supports two geographically separated chromosomal variants in europe, 2 different diploid chromosome numbers, 2n = 54 and 2n = 56, have been described in the lesser horseshoe bat (rhinolophushipposideros). the eastern form with 2n = 56 extends from the czech republic to greece. to date, specimens with 54 chromosomes have been reported only from spain and germany. this study expands the distributional area of the western variant to ireland. strikingly, this distribution of european chromosomal variants is in contrast to the available molecular data that ...201627333200
which temporal resolution to consider when investigating the impact of climatic data on population dynamics? the case of the lesser horseshoe bat (rhinolophus hipposideros).climatic variables are often considered when studying environmental impacts on population dynamics of terrestrial species. however, the temporal resolution considered varies depending on studies, even among studies of the same taxa. most studies interested in climatic impacts on populations tend to average climatic data across timeframes covering life cycle periods of the organism in question or longer, even though most climatic databases provide at least a monthly resolution. we explored the im ...201728695278
seasonal changes in spermatogenesis of the japanese lesser horseshoe bat, rhinolophus cornutus from a morphological viewpoint.seasonal changes in spermatogenesis of japanese lesser horseshoe bats, rhinolophus cornutus, captured in aomori prefecture (japan) were examined by light microscopy. in march, the seminiferous tubules revealed almost no lumen. the seminiferous epithelium consisted of sertoli cells and spermatogonia. the interstitium occupied a relatively large area. in june, the seminiferous tubules gradually increased in diameter. lumen was clearly seen at the center of seminiferous tubules. mitotic figures of ...200212484443
differential rates of genic and chromosomal evolution in bats of the family for nondifferentially stained chromosomes from 10 species of rhinolophus (chiroptera: rhinolophidae) suggest a conserved chromosomal evolution. g-banded chromosomes for three well differentiated species (rhinolophus hipposideros, rhinolophus blasii, and rhinolophus acuminatus) corroborate a low level of gross chromosomal rearrangements. additionally, a comparison between g-banded chromosomes of rhinolophus (rhinolophidae) and hipposideros (hipposideridae) suggests extreme conservatism in ch ...19883169543
moth hearing in response to bat echolocation calls manipulated independently in time and frequency.we measured the auditory responses of the noctuid moth noctua pronuba to bat echolocation calls which were manipulated independently in time and frequency. such manipulations are important in understanding how insect hearing influences the evolution of echolocation call characteristics. we manipulated the calls of three bat species (rhinolophus hipposideros, myotis nattereri and pipistrellus pipistrellus) that use different echolocation call features by doubling their duration or reducing their ...200011467425
detection of coronaviruses in bats of various species in italy.bats are natural reservoirs for many mammalian coronaviruses, which have received renewed interest after the discovery of the severe acute respiratory syndrome (sars) and the middle east respiratory syndrome (mers) cov in humans. this study describes the identification and molecular characterization of alphacoronaviruses and betacoronaviruses in bats in italy, from 2010 to 2012. sixty-nine faecal samples and 126 carcasses were tested using pan-coronavirus rt-pcr. coronavirus rnas were detected i ...201324184965
detection of diverse novel bat astrovirus sequences in the czech republic.astroviruses are a major cause of gastroenteritis in humans and animals. recently, novel groups of astroviruses were identified in apparently healthy insectivorous bats. we report the detection of diverse novel astrovirus sequences in nine different european bat species: eptesicus serotinus, hypsugo savii, myotis emarginatus, m. mystacinus, nyctalus noctula, pipistrellus nathusii or p. pygmaeus, p. pipistrellus, vespertilio murinus, and rhinolophus hipposideros. in six bat species, astrovirus se ...201526273815
the peripheral auditory characteristics of noctuid moths: responses to the search-phase echolocation calls of batsthe noctuid moths agrotis segetum and noctua pronuba show peak auditory sensitivity between 15 and 25 khz, and a maximum sensitivity of 35 db spl. a. segetum shows a temporal integration time of 69 ms. it is predicted that bats using high-frequency and short-duration calls will be acoustically less apparent to these moths. short-duration frequency-modulated (fm) calls of plecotus auritus are not significantly less acoustically apparent than those of other fm bats with slightly longer call durati ...19969318627
characterization of a novel g3p[3] rotavirus isolated from a lesser horseshoe bat: a distant relative of feline/canine rotaviruses.bats are considered important animal reservoirs for many viruses pathogenic to humans. an approach based on viral metagenomics was used to study gut specimens from 78 insectivorous bats in yunnan province, china. seventy-four reads were found to be related to group a rotavirus (rva). further reverse transcription-pcr screening and viral isolation on cell cultures confirmed the presence of a novel rva strain, named rva/bat-tc/mslh14/2012/g3p[3], in 1 (6%) of 16 lesser horseshoe bats. full genomic ...201324027312

detection and characterization of a novel reassortant mammalian orthoreovirus in bats in europe.a renewed interest in mammalian orthoreoviruses (mrvs) has emerged since new viruses related to bat mrv type 3, detected in europe, were identified in humans and pigs with gastroenteritis. this study reports the isolation and characterization of a novel reassortant mrv from the lesser horseshoe bat (rhinolophus hipposideros). the isolate, here designated batmrv1-it2011, was first identified by electron microscopy and confirmed using pcr and virus-neutralization tests. the full genome sequence wa ...201526569289
identification of sars-like coronaviruses in horseshoe bats (rhinolophus hipposideros) in slovenia.bats have been identified as a natural reservoir for an increasing number of emerging zoonotic viruses, such as hendra virus, nipah virus, ebola virus, marburg virus, rabies and other lyssaviruses. recently, a large number of viruses closely related to members of the genus coronavirus have been associated with severe acute respiratory syndrome (sars) and detected in bat species. in this study, samples were collected from 106 live bats of seven different bat species from 27 different locations in ...201020217155
population genetic structure and demographic history of the endemic formosan lesser horseshoe bat (rhinolophus monoceros).intraspecific phylogenies can provide useful insights into how populations have been shaped by historical and contemporary processes. taiwan formed around 5 million years ago from tectonic uplift, and has been connected to mainland asia several times since its emergence. a central mountain range runs north to south, bisecting the island, and potentially impedes gene flow along an east-west axis. the formosan lesser horseshoe bat (rhinolophus monoceros) is endemic to taiwan, where it is found mai ...200616629817
cycle of the seminiferous epithelium in the java fruit bat (pteropus vampyrus) and the japanese lesser horseshoe bat (rhinolophus cornutus).the cycle of the seminiferous epithelium in the java fruit bat, pteropus vampyrus, and the japanese lesser horseshoe bat, rhinolophus cornutus, was investigated by light microscopy and the characteristics of spermiogenesis were compared between these two species. in the java fruit bat, the cycle of the seminiferous epithelium was divided into 11 stages and developing spermatids were subdivided into 13 steps. while in the japanese lesser horseshoe bat, the cycle of the seminiferous epithelium was ...200111503905
white-nose syndrome fungus: a generalist pathogen of hibernating traits and phylogeny can determine infection risk by driving pathogen transmission and its ability to infect new hosts. predicting such risks is critical when designing disease mitigation strategies, and especially as regards wildlife, where intensive management is often advocated or prevented by economic and/or practical reasons. we investigated pseudogymnoascus [geomyces] destructans infection, the cause of white-nose syndrome (wns), in relation to chiropteran ecology, behaviour and phylo ...201424820101
four new mitochondrial genomes and the increased stability of evolutionary trees of mammals from improved taxon sampling.we have sequenced four new mitochondrial genomes to improve the stability of the tree for placental mammals; they are two insectivores (a gymnure, echinosorex gymnurus and formosan shrew soriculus fumidus); a formosan lesser horseshoe bat (rhinolophus monoceros); and the new zealand fur seal (arctocephalus forsteri). a revision to the hedgehog sequence (erinaceus europaeus) is also reported. all five are from the laurasiatheria grouping of eutherian mammals. on this new data set there is a stron ...200212446798
determinants of echolocation call frequency variation in the formosan lesser horseshoe bat (rhinolophus monoceros).the origin and maintenance of intraspecific variation in vocal signals is important for population divergence and speciation. where vocalizations are transmitted by vertical cultural inheritance, similarity will reflect co-ancestry, and thus vocal divergence should reflect genetic structure. horseshoe bats are characterized by echolocation calls dominated by a constant frequency component that is partly determined by maternal imprinting. although previous studies showed that constant frequency c ...200919692399
echolocation call structure and intensity in five species of insectivorous bats.echolocation call intensity was measured in the laboratory for five species of british insectivorous bats in free flight and in the hand. all species showed similar call intensities of between 80 and 90 db pespl (peak equivalent spl) at 1 m during flight except plecotus auritus, whose call intensity was between 68 and 77 db pespl at 1 m. calls from stationary bats were about 13 db less intense than calls during flight. a method is proposed to measure the root mean square (rms) amplitude of echol ...19957699316
evidence for two karyotypic variants of the lesser horseshoe bat ( rhinolophus hipposideros , chiroptera, mammalia) in central europe.three different diploid chromosome numbers (2n = 54, 56 and 58) have been reported in the lesser horseshoe bat, rhinolophus hipposideros. asia minor and the middle east are inhabited by r. hipposideros specimens with 58 chromosomes. in europe, specimens with 56 chromosomes have been recorded from several localities in the czech republic, slovakia, italy and greece. up to now, specimens with 54 chromosomes have been reported only from spain and possibly from switzerland. with the record of 54 chr ...201323635426
