| predicting species distributions using record centre data: multi-scale modelling of habitat suitability for bat roosts. | conservation increasingly operates at the landscape scale. for this to be effective, we need landscape scale information on species distributions and the environmental factors that underpin them. species records are becoming increasingly available via data centres and online portals, but they are often patchy and biased. we demonstrate how such data can yield useful habitat suitability models, using bat roost records as an example. we analysed the effects of environmental variables at eight spat ... | 2015 | 26053548 |
| reproduction of rescued vespertilionid bats (nyctalus noctula) in captivity: veterinary and physiologic aspects. | long-term conservation and educational activities of numerous nongovernmental organizations have greatly increased public awareness about bats and their lifestyle. as a result, there is growing public concern about threats to bat populations. many species of bats declined over recent decades and there is great demand for medical services to help injured or diseased bats. veterinary clinicians dealing with such cases have to consider many issues, including ethical issues associated with the delay ... | 2017 | 28169186 |
| novel hantavirus identified in european bat species nyctalus noctula. | hantaviruses are emerging rna viruses that cause human diseases predominantly in asia, europe, and the americas. besides rodents, insectivores and bats serve as hantavirus reservoirs. we report the detection and genome characterization of a novel bat-borne hantavirus isolated from insectivorous common noctule bat. the newfound virus was tentatively named as brno virus. | 2017 | 28025098 |
| common noctule bats are sexually dimorphic in migratory behaviour and body size but not wing shape. | within the large order of bats, sexual size dimorphism measured by forearm length and body mass is often female-biased. several studies have explained this through the effects on load carrying during pregnancy, intrasexual competition, as well as the fecundity and thermoregulation advantages of increased female body size. we hypothesized that wing shape should differ along with size and be under variable selection pressure in a species where there are large differences in flight behaviour. we te ... | 2016 | 27880791 |
| habitat use of migratory bats killed during autumn at wind turbines. | the killing of large numbers of migratory bats at wind turbines is a pressing conservation problem. even though avoidance and mitigation measures could benefit from a better knowledge of the species' migratory habits, we lack basic information about what habitats and corridors bats use during migration. we studied the isotopic niche dimensions of three bat species that are frequently killed at wind turbines in germany: non-migratory pipistrellus pipistrellus, mid-distance migratory nyctalus noct ... | 2016 | 27411249 |
| habitat use of bats in relation to wind turbines revealed by gps tracking. | worldwide, many countries aim at countering global climate change by promoting renewable energy. yet, recent studies highlight that so-called green energy, such as wind energy, may come at environmental costs, for example when wind turbines kill birds and bats. using miniaturized gps loggers, we studied how an open-space foraging bat with high collision risk with wind turbines, the common noctule nyctalus noctula (schreber, 1774), interacts with wind turbines. we compared actual flight trajector ... | 2016 | 27373219 |

| testing hypotheses of bat baculum function with 3d models derived from microct. | the baculum (os penis) has been extensively studied as a taxon-specific character in bats and other mammals but its mechanical function is still unclear. there is a wide consensus in the literature that the baculum is probably a sexually selected character. using a novel approach combining postmortem manipulation and three-dimensional (3d) imaging, we tested two functional hypotheses in the common noctule bat nyctalus noctula, the common pipistrelle pipistrellus pipistrellus, and nathusius' pipi ... | 2015 | 25655647 |
| tracking post-hibernation behavior and early migration does not reveal the expected sex-differences in a "female-migrating" bat. | long-distance migration is a rare phenomenon in european bats. genetic analyses and banding studies show that females can cover distances of up to 1,600 km, whereas males are sedentary or migrate only short distances. the onset of this sex-biased migration is supposed to occur shortly after rousing from hibernation and when the females are already pregnant. we therefore predicted that the sexes are exposed to different energetic pressures in early spring, and this should be reflected in their be ... | 2014 | 25517947 |
| wind farm facilities in germany kill noctule bats from near and far. | over recent years, it became widely accepted that alternative, renewable energy may come at some risk for wildlife, for example, when wind turbines cause large numbers of bat fatalities. to better assess likely populations effects of wind turbine related wildlife fatalities, we studied the geographical origin of the most common bat species found dead below german wind turbines, the noctule bat (nyctalus noctula). we measured stable isotope ratios of non-exchangeable hydrogen in fur keratin to se ... | 2014 | 25118805 |

| male dispersal in the noctule bat (nyctalus noctula): where are the limits? | studying the dispersal behaviour of small, volant, and nocturnal animals such as microchiropterans with direct methods (banding--recapture, telemetry) is a very difficult task. the development of easily scorable and highly variable genetic markers nowadays allows us to study some aspects of dispersal indirectly, using population genetics. here, we applied these indirect methods to characterize male dispersal behaviour in a european bat species. the eight microsatellite loci analysed were highly ... | 1999 | 10518319 |
| no evidence of bottleneck in the postglacial recolonization of europe by the noctule bat (nyctalus noctula). | during the pleistocene, the habitat of the noctule bat (nyctalus noctula) was limited to small refuge areas located in southern europe, whereas the species is now widespread across this continent. using mtdna (control region and nd1 gene) polymorphisms, we asked whether this recolonization occurred through bottlenecks and whether it was accompanied by population growth. sequences of the second hypervariable domain of the control region were obtained from 364 noctule bats representing 18 colonies ... | 1999 | 28565510 |

| variability and repeatability of noctule bat migration in central europe: evidence for partial and differential migration. | each year, large numbers of bats move across europe between their summer and winter areas, yet even though many of them are endangered and legally protected, we are unaware about many aspects of their migratory behaviour. here, taking nyctalus noctula as a model species, we used stable hydrogen isotopic values in fur ( δ2hf) as an endogenous marker to shed light on the migratory behaviour of more than 1000 bats from hibernacula across central europe. specifically, we asked the following question ... | 2018 | 30963889 |
| proximity sensors on common noctule bats reveal evidence that mothers guide juveniles to roosts but not food. | female bats of temperate zones often communally rear their young, which creates ideal conditions for naive juveniles to find or learn about resources via informed adults. however, studying social information transfer in elusive and small-bodied animals in the wild is difficult with traditional tracking techniques. we used a novel 'next-generation' proximity sensor system (bats) to investigate if and how juvenile bats use social information in acquiring access to two crucial resources: suitable r ... | 2019 | 30958135 |
| common noctules exploit low levels of the aerosphere. | aerial habitats present a challenge to find food across a large potential search volume, particularly for insectivorous bats that rely on echolocation calls with limited detection range and may forage at heights over 1000 m. to understand how bats use vertical space, we tracked one to five foraging flights of eight common noctules (nyctalus noctula). bats were tracked for their full foraging session (87.27 ± 24 min) using high-resolution atmospheric pressure radio transmitters that allowed us to ... | 2019 | 30891300 |

| aerial-hawking bats adjust their use of space to the lunar cycle. | animals change their habitat use in response to spatio-temporal fluctuation of resources. some resources may vary periodically according to the moonphase. yet it is poorly documented how animals, particularly nocturnal mammals, adjust their use of space in response to the moonphase.here, we asked if an obligate nocturnal mammal, the aerial-hawking common noctule bat (nyctalus noctula), adjusts its 3-dimensional flight behaviour and habitat use to the lunar period. using miniaturized gps loggers, ... | 2018 | 30123507 |
| insectivorous bats respond to vegetation complexity in urban green spaces. | structural complexity is known to determine habitat quality for insectivorous bats, but how bats respond to habitat complexity in highly modified areas such as urban green spaces has been little explored. furthermore, it is uncertain whether a recently developed measure of structural complexity is as effective as field-based surveys when applied to urban environments. we assessed whether image-derived structural complexity (mig) was as/more effective than field-based descriptors in this environm ... | 2018 | 29607021 |
| oxidation of linoleic and palmitic acid in pre-hibernating and hibernating common noctule bats revealed by 13c breath testing. | mammals fuel hibernation by oxidizing saturated and unsaturated fatty acids from triacylglycerols in adipocytes, yet the relative importance of these two categories as an oxidative fuel may change during hibernation. we studied the selective use of fatty acids as an oxidative fuel in noctule bats (nyctalus noctula). pre-hibernating noctule bats that were fed 13c-enriched linoleic acid (la) showed 12 times higher tracer oxidation rates compared with conspecifics fed 13c-enriched palmitic acid (pa ... | 2018 | 29361583 |
| determinants of spring migration departure decision in a bat. | migratory decisions in birds are closely tied to environmental cues and fat stores, but it remains unknown if the same variables trigger bat migration. to learn more about the rare phenomenon of bat migration, we studied departure decisions of female common noctules (nyctalus noctula) in southern germany. we did not find the fattening period that modulates departure decisions in birds. female noctules departed after a regular evening foraging session, uniformly heading northeast. as the day of y ... | 2017 | 28931730 |
