| description of riouxgolvania kapapkamui sp. n. (nematoda: muspiceoidea: muspiceidae), a peculiar intradermal parasite of bats in hokkaido, japan. | riouxgolvania kapapkamui sp. n. (nematoda: muspiceoidea: muspiceidae), a peculiar intradermal parasite, is described based on gravid adults, eggs, and first-, second-, and third-stage larvae collected from dermal nodules formed in myotis macrodactylus and myotis ikonnikovi bats from hokkaido, japan. the nematode is readily distinguished from 3 previously described congeners in having a globular body with brown, transverse striae in the anterior region of fully grown females. the third-stage larv ... | 2012 | 22493947 |
| genetic diversity and phylogenetic analysis of newly discovered bat astroviruses in korea. | bats have been identified as a natural reservoir for several potentially zoonotic viruses. recently, astroviruses have been reported in bats in many countries, but not korea. we collected 363 bat samples from thirteen species at twenty-nine sites in korea across 2016 and tested them for astrovirus. the detection of the rna-dependent rna polymerase (rdrp) gene in bat astroviruses was confirmed in thirty-four bats across four bat species in korea: twenty-five from miniopterus fuliginosusi, one fro ... | 2018 | 30097745 |
| stereotypy and variability of social calls among clustering female big-footed myotis (myotis macrodactylus). | echolocating bats have developed advanced auditory perception systems, predominantly using acoustic signaling to communicate with each other. they can emit a diverse range of social calls in complex behavioral contexts. this study examined the vocal repertoire of five pregnant big-footed myotis bats (myotis macrodactylus). in the process of clustering, the last individual to return to the colony (li) emitted social calls that correlated with behavior, as recorded on a pc-based digital recorder. ... | 2018 | 29515093 |
| social vocalizations of big-footed myotis (myotis macrodactylus) during foraging. | acoustic signals play a crucial role in transmitting information and maintaining social stability in gregarious animals, especially in echolocating bats, which rely primarily on biological sonar for navigating in the dark. in the context of foraging without relying on tactile, visual or olfactory cues, acoustic signals convey information not only on food but also on ownership and defense of resources. however, studies on such information remain fragmentary. in the present study, we aim to docume ... | 2019 | 30585415 |
| the epidemiological characteristics of the korean bat paramyxovirus between 2016 and 2019. | bats are considered reservoirs of severe emerging human pathogens. notably, bats host major mammalian paramyxoviruses from the family paramyxoviridae, order mononegavirales. in this study, paramyxoviruses were investigated by reverse transcription semi-nested polymerase chain reaction (rt-semi-nested pcr) and reverse transcription polymerase chain reaction (rt-pcr), based on the rt-semi-nested pcr using the consensus paramyxovirus primers targeting the rna dependent-rna-polymerase (rdrp) region. ... | 2020 | 32512880 |
| long-term surveillance of bat coronaviruses in korea: diversity and distribution pattern. | bats harbour diverse coronaviruses (covs), some of which are associated with zoonotic infections, as well as inter-species transmission. in this study, a total of 512 bat faecal samples from the bat habitats at different geographical locations in south korea were investigated between 2016 and 2019. seventy-eight samples were positive for coronaviruses (15.2%), comprising 68 alphacoronaviruses (13.3%) and 10 betacoronaviruses (2.0%). the positive rates tended to increase during the awakening (apr ... | 2020 | 32473082 |
| dynamic adjustment of echolocation pulse structure of big-footed myotis (myotis macrodactylus) in response to different habitats. | studying relationships between characteristics of sonar pulses and habitat clutter level is important for the understanding of signal design in bat echolocation. however, most studies have focused on overall spectral and temporal parameters of such vocalizations, with focus less on potential variation in frequency modulation rates (mrs) occurring within each pulse. in the current study, frequency modulation (fm) characteristics were examined in echolocation pulses recorded from big-footed myotis ... | 2014 | 25234900 |
| situational and age-dependent decision making during life threatening distress in myotis macrodactylus. | echolocation and audiovocal communication have been studied extensively in bats. the manner in which these abilities are incorporated within escape behaviors during life-threatening distress is largely unknown. here we tested the hypothesis that behavioral response profiles expressed during distress are relatively stereotypic given their evolutionary adaptations to avoid predators. we subjected juvenile and adult big-footed myotis (myotis macrodactylus) to a sequence of three types of life threa ... | 2015 | 26181328 |
| complete mitochondrial genome of a large-footed bat, myotis macrodactylus (vespertilionidae). | the complete mitochondrial genome was sequenced and characterized newly from a large-footed bat, myotis macrodactylus (vespertilionidae). the total length of the m. macrodactylus genome is 17,562 bp, with a base composition of 34.0% a, 29.9% t, 23.0% c and 13.0% g. a short sequence of catacg is repeated 60 times in d-loop region. amino acid of m. macrodactylus was 92.7% similar to that of m. formosus. nucleotide similarity was 86.6% in all the other gene regions except for d-loop with low 66.8% ... | 2015 | 24102594 |
| acoustic identification of eight species of bat (mammalia: chiroptera) inhabiting forests of southern hokkaido, japan: potential for conservation monitoring. | assessing the impact of forest management on bat communities requires a reliable method for measuring patterns of habitat use by individual species. a measure of activity can be obtained by monitoring echolocation calls, but identification of species is not always straightforward. we assess the feasibility of using analysis of time-expanded echolocation calls to identify free-flying bats in the tomakomai experimental forest of hokkaido university, hokkaido, northern japan. echolocation calls of ... | 2004 | 15459453 |
| occurrence of centrioles in interphasic hepatocytes of bat and chicken. | occurrence of centrioles in non-dividing hepatocytes was examined by electron microscopy in the bat, miniopterus schreibersi (kuhl) and myotis macrodactylus (temminck), and the chicken. in both species centrioles were mostly found in the apical hyaloplasmic halo which was distinct in the chicken but rather indistinct in the bat. there was no difficulty in locating centrioles in the hepatocytes of either species. in the chicken centrioles were found in the attenuated apical cytoplasmic areas of 4 ... | 1978 | 718390 |
