molecular evidence of chlamydia-like organisms in the feces of myotis daubentonii bats.	chlamydia-like organisms (clos) are recently identified members of the chlamydiales order. clos share intracellular lifestyles and biphasic developmental cycles, and they have been detected in environmental samples as well as in various hosts such as amoebae and arthropods. in this study, we screened bat feces for the presence of clos by molecular analysis. using pan-chlamydiales pcr targeting the 16s rrna gene, chlamydiales dna was detected in 54% of the specimens. pcr amplification, sequencing ...	2017	27815278
parasites of parasites of bats: laboulbeniales (fungi: ascomycota) on bat flies (diptera: nycteribiidae) in central europe.	bat flies (streblidae and nycteribiidae) are among the most specialized families of the order diptera. members of these two related families have an obligate ectoparasitic lifestyle on bats, and they are known disease vectors for their hosts. however, bat flies have their own ectoparasites: fungi of the order laboulbeniales. in europe, members of the nycteribiidae are parasitized by four species belonging to the genus arthrorhynchus. we carried out a systematic survey of the distribution and fun ...	2017	28222795
flight in ground effect dramatically reduces aerodynamic costs in bats.	most flying animals, from insects to seabirds [1], perform flights close to ground or water when taking off or landing [2], drinking, and feeding [3-5] or when traveling near water surfaces [1, 6, 7]. when flying close to a surface within approximately one wingspan, the surface acts as an aerodynamic mirror, interrupting the downwash [8, 9], resulting in increased pressure underneath the wing and suppression of wingtip vortex development [10]. this aerodynamic interaction lowers the energy added ...	2018	30344122
no effect of artificial light of different colors on commuting daubenton's bats (myotis daubentonii) in a choice experiment.	progressive illumination at night poses an increasing threat to species worldwide. light at night is particularly problematic for bats as most species are nocturnal and often cross relatively large distances when commuting between roosts and foraging grounds. earlier studies have shown that illumination of linear structures in the landscape disturbs commuting bats, and that the response of bats to light may strongly depend on the light spectrum. here, we studied the impact of white, green, and r ...	2018	29808964
spring weather conditions influence breeding phenology and reproductive success in sympatric bat populations.	climate is known to influence breeding phenology and reproductive success in temperate-zone bats, but long-term population level studies and interspecific comparisons are rare. investigating the extent to which intrinsic (i.e. age), and extrinsic (i.e. spring weather conditions), factors influence such key demographic parameters as the proportion of females becoming pregnant, or completing lactation, each breeding season, is vital to understanding of bat population ecology and life-history trait ...	2018	29635800
molecular epidemiology and evolution of european bat lyssavirus 2.	bat rabies cases in europe are mainly attributed to two lyssaviruses, namely european bat lyssavirus 1 (eblv-1) and european bat lyssavirus 2 (eblv-2). prior to the death of a bat worker in finland in 1985, very few bat rabies cases were reported. enhanced surveillance in the two subsequent years (1986-1987) identified 263 cases (more than a fifth of all reported cases to date). between 1977 and 2016, 1183 cases of bat rabies were reported, with the vast majority (>97%) being attributed to eblv- ...	2018	29303971
detection and characterization of distinct alphacoronaviruses in five different bat species in denmark.	bat populations harbour a multitude of viruses; some of these are pathogenic or potentially pathogenic in other animals or humans. therefore, it is important to monitor the populations and characterize these viruses. in this study, the presence of coronaviruses (covs) in different species of danish bats was investigated using active surveillance at different geographical locations in denmark. faecal samples were screened for the presence of covs using pan-cov real-time rt-pcr assays. the amplico ...	2018	30208582
frequent or scarce? damage to flight-enabling body parts in bats (chiroptera).	bat wings are characterized by high endurance, and these mammals have developed a number of adaptations that protect them from falling into obstacles and potential injuries. however, in bat populations, there are individuals with visible fresh or healed injuries to the flight-enabling body parts. the aim of this research was to determine the differences in the occurrence of wing membrane damages among species of bats that differ in ecology and behavior. the study was conducted in southern and we ...	2019	31329631
virus- and interferon alpha-induced transcriptomes of cells from the microbat myotis daubentonii.	antiviral interferons (ifn-alpha/beta) are possibly responsible for the high tolerance of bats to zoonotic viruses. previous studies focused on the ifn system of megabats (suborder yinpterochiroptera). we present statistically robust rna sequencing (rna-seq) data on transcriptomes of cells from the "microbat" myotis daubentonii (suborder yangochiroptera) responding at 6 and 24 h to either an ifn-inducing virus or treatment with ifn. our data reveal genes triggered only by virus, either in both h ...	2019	31465999
genetic diversity of the yokose virus, xybx1332, isolated from bats (myotis daubentonii) in china.	yokose virus was first isolated from bats (miniopterus fuliginosus) collected in yokosuka, japan, in 1971, and is a new member of the family flaviviridae, genus flavivirus. in this study, we isolated a yokose virus from a serum sample of myotis daubentonii (order chiroptera, family vespertilionidae) collected in yunnan province, china in 2013.	2019	30634973
artificial illumination near rivers may alter bat-insect trophic interactions.	artificial illumination at night represents an increasingly concerning threat to ecosystems worldwide, altering persistence, behaviour, physiology and fitness of many organisms and their mutual interactions, in the long-term affecting ecosystem functioning. bats are very sensitive to artificial light at night because they are obligate nocturnal and feed on insects which are often also responsive to lights. here we tested the effects of led lighting on prey-predator interactions at riverine ecosy ...	2019	31284209
habitat usage of daubenton's bat (myotis daubentonii), common pipistrelle (pipistrellus pipistrellus), and soprano pipistrelle (pipistrellus pygmaeus) in a north wales upland river catchment.	distributions of daubenton's bat (myotis daubentonii), common pipistrelle, (pipistrellus pipistrellus), and soprano pipistrelle (pipistrellus pygmaeus) were investigated along and altitudinal gradient of the lledr river, conwy, north wales, and presence assessed in relation to the water surface condition, presence/absence of bank-side trees, and elevation. ultrasound recordings of bats made on timed transects in summer 1999 were used to quantify habitat usage. all species significantly preferred ...	2019	31031948
differences in seasonal survival suggest species-specific reactions to climate change in two sympatric bat species.	long-lived animals with a low annual reproductive output need a long time to recover from population crashes and are, thus, likely to face high extinction risk, if the current global environmental change will increase mortality rates. to aid conservation of those species, knowledge on the variability of mortality rates is essential. unfortunately, however, individual-based multiyear data sets that are required for that have only rarely been collected for free-ranging long-lived mammals. here, we ...	2019	31380063

live fast, don't die young: survival-reproduction trade-offs in long-lived income breeders.	trade-offs between survival and reproduction are at the core of life-history theory, and essential to understanding the evolution of reproductive tactics as well as population dynamics and stability. factors influencing these trade-offs are multiple and often addressed in isolation. further problems arise as reproductive states and survival in wild populations are estimated based on imperfect and potentially biased observation processes, which might lead to flawed conclusions. in this study, we ...	2019	30737781
effect of sex and reproductive status on the immunity of the temperate bat myotis daubentonii.	studies of immunity in bat species are rare. however, it is important to determine immunological variations to identify factors influencing the health status of these endangered mammals from an evolutionary, ecological, conservation, and public health point of view. immunity is highly variable and can be influenced by both internal (e.g. hormone levels, energy demand) and external factors (e.g. pathogens, climate). as bats have some peculiar ecological, energetic, and putative immunological char ...	2019	32218715
metal and metalloid exposure and oxidative status in free-living individuals of myotis daubentonii.	metal elements, ubiquitous in the environment, can cause negative effects in long-lived organisms even after low but prolonged exposure. insectivorous bats living near metal emission sources can be vulnerable to such contaminants. although it is known that bats can bioaccumulate metals, little information exists on the effects of metal elements on their physiological status. for example, oxidative status markers are known to vary after detoxification processes and immune reactions. here, for two ...	2019	30439584
the sonar beam of macrophyllum macrophyllum implies ecological adaptation under phylogenetic constraint.	all animals are adapted to their ecology within the bounds of their evolutionary heritage. echolocating bats clearly show such adaptations and boundaries through their biosonar call design. adaptations include not only the overall time-frequency structure, but also the shape of the emitted echolocation beam. macrophyllum macrophyllum is unique within the phyllostomid family, being the only species to predominantly hunt for insects in the open, on or above water, and as such it presents an intere ...	2020	32398318
phenology of reproductive condition varies with age and spring weather conditions in male myotis daubentonii and m. nattereri (chiroptera: vespertilionidae).	we examine the extent to which intrinsic and extrinsic factors influence reproductive phenology in male bats at the population level. using data from thirteen breeding seasons (2006-2018), encompassing the reproductive histories of 1546 myotis daubentonii and 530 m. nattereri males, we compare rates of sexual maturation and the temporal distribution of phases of spermatogenesis between juvenile (born that season) and adult (born in previous seasons) males. we found that (i) higher proportions of ...	2020	32313091
between roost contact is essential for maintenance of european bat lyssavirus type-2 in myotis daubentonii bat reservoir: 'the swarming hypothesis'.	many high-consequence human and animal pathogens persist in wildlife reservoirs. an understanding of the dynamics of these pathogens in their reservoir hosts is crucial to inform the risk of spill-over events, yet our understanding of these dynamics is frequently insufficient. viral persistence in a wild bat population was investigated by combining empirical data and in-silico analyses to test hypotheses on mechanisms for viral persistence. a fatal zoonotic virus, european bat lyssavirus type 2 ...	2020	32015375
retinal ganglion cell topography and spatial resolving power in echolocating and non-echolocating bats.	bats are nocturnal mammals known for their ability to echolocate, yet all bats can see, and most bats of the family pteropodidae (fruit bats) do not echolocate - instead they rely mainly on vision and olfaction to forage. we investigated whether echolocating bats, given their limited reliance on vision, have poorer spatial resolving power (srp) than pteropodids and whether tongue click echolocating fruit bats differ from non-echolocating fruit bats in terms of visual performance. we compared the ...	2020	32818939
serological survey of lyssaviruses in polish bats in the frame of passive rabies surveillance using an enzyme-linked immunosorbent assay.	background: bats are known to host a number of nonpathogenic viruses, as well as highly pathogenic viruses causing fatal diseases like rabies. serological surveys as part of active and passive bat rabies surveillance mainly use seroneutralization assays, demonstrating the presence of lyssavirus-specific antibodies in a variety of european bats, particularly against european bat lyssaviruses type 1 (eblv-1). here, we present the first serological survey in european bats of this kind during which ...	2020	32121200
