detection of virus-related sequences associated with potential etiologies of hepatitis in liver tissue samples from rats, mice, shrews, and bats.hepatitis is a major global health concern. however, the etiology of 10-20% hepatitis cases remains unclear. some hepatitis-associated viruses, like the hepatitis e virus, are zoonotic pathogens. rats, shrews, and bats are reservoirs for many zoonotic pathogens. therefore, understanding the virome in the liver of these animals is important for the investigation of the etiologies of hepatitis and monitoring the emerging zoonotic viruses. in this study, viral metagenomics and pcr methods were used ...202134177835
insectivorous bat reproduction and human cave visitation in cambodia: a perfect conservation storm?cave roosting bats represent an important component of southeast asian bat diversity and are vulnerable to human disturbance during critical reproductive periods (pregnancy, lactation and weaning). because dramatic growth of cave tourism in recent decades has raised concerns about impacts on cave bats in the region, we assessed the reproductive phenology of two insectivorous species (hipposideros larvatus sensu lato and taphozous melanopogon) at three caves in cambodia for 23 months in 2014-2016 ...201829709036
microclimate and physiological effects in the roosts of cave dwelling bats: implications in roost selection and conservation in sarawak, malaysian borneo.bats play crucial ecological and economic roles. however, this group of mammals is largely threatened due to anthropogenic activities inside or around their caves. in the present study, we investigate the effects of cave microclimate and physiological parameters on bat roost preference in fairy cave nature reserve (fairy cave nr). the microclimate and physiological parameters including temperature (°c), relative humidity (rh), light intensity (lux), air flow, passage dimension (m), roost height ...201830520355
new locality records of ixodes granulatus and ixodes vespertilionis (acari: ixodidae) from tree-shrews (scandentia: tupaiidae) and bats (chiroptera: hipposideridae) in laos.between may and june 2015, 512 bats, six rodents, and six tree-shrews were examined for ectoparasites in vientiane and khammouane provinces, laos. thirty-seven ticks (33 females and four males) identified as ixodes granulatus supino were collected from four individuals of the northern tree-shrew, tupaia belangeri (wagner) (scandentia:tupaiidae), and one female of ixodes vespertilionis koch was collected from one individual of the intermediate leaf-nosed bat, hipposideros larvatus (horsfield) (ch ...201829897563
molecular detection and sequence characterization of diverse rhabdoviruses in bats, china.the rhabdoviridae is among the most diverse families of rna viruses and currently classified into 18 genera with some rhabdoviruses lethal to humans and other animals. herein, we describe genetic characterization of three novel rhabdoviruses from bats in china. of these, two viruses (jinghong bat virus and benxi bat virus) found in rhinolophus bats showed a phylogenetic relationship with vesiculoviruses, and sequence analyses indicate that they represent two new species within the genus vesiculo ...201829196194
karyotype evolution in rhinolophus bats (rhinolophidae, chiroptera) illuminated by cross-species chromosome painting and g-banding comparison.rhinolophus (rhinolophidae) is the second most speciose genus in chiroptera and has extensively diversified diploid chromosome numbers (from 2n = 28 to 62). in spite of many attempts to explore the karyotypic evolution of this genus, most studies have been based on conventional giemsa staining rather than g-banding. here we have made a whole set of chromosome-specific painting probes from flow-sorted chromosomes of aselliscus stoliczkanus (hipposideridae). these probes have been utilized to esta ...200717899409
karyotypic evolution and phylogenetic relationships in the order chiroptera as revealed by g-banding comparison and chromosome painting.bats are a unique but enigmatic group of mammals and have a world-wide distribution. the phylogenetic relationships of extant bats are far from being resolved. here, we investigated the karyotypic relationships of representative species from four families of the order chiroptera by comparative chromosome painting and banding. a complete set of painting probes derived from flow-sorted chromosomes of myotis myotis (family vespertilionidae) were hybridized onto metaphases of cynopterus sphinx (2n = ...200717310301
counting in the dark: non-intrusive laser scanning for population counting and identifying roosting bats.population surveys and species recognition for roosting bats are either based on capture, sight or optical-mechanical count methods. however, these methods are intrusive, are tedious and, at best, provide only statistical estimations. here, we demonstrated the successful use of a terrestrial light detection and ranging (lidar) laser scanner for remotely identifying and determining the exact population of roosting bats in caves. lidar accurately captured the 3d features of the roosting bats and t ...201222826802
'compromise' in echolocation calls between different colonies of the intermediate leaf-nosed bat (hipposideros larvatus).each animal population has its own acoustic signature which facilitates identification, communication and reproduction. the sonar signals of bats can convey social information, such as species identity and contextual information. the goal of this study was to determine whether bats adjust their echolocation call structures to mutually recognize and communicate when they encounter the bats from different colonies. we used the intermediate leaf-nosed bats (hipposideros larvatus) as a case study to ...201627029005
