Insectivorous bats provide important ecosystem services, especially by suppressing and controlling the insects’ biomass. To empirically quantify the number of insects consumed by European vespertilionid bats per night, we estimated their ratio of dry mass of feces to mass of consumed insects. This study combines the results of feeding in captivity...

Co-existence of bats with a wide range of infectious agents relates to their co-evolutionary history and specific physiology. Here, we examined blood samples collected during hibernation and the post-hibernation period to assess the influence of trypanosomes and babesias on the health status of 50 Noctule bats (Nyctalus noctula) using nested PCR. T...

Long-term torpor or hibernation is the main adaptation for food-limited periods or seasons in mammals. Aimed to study the impact of sex, age, body mass and grouping on hibernation strategy of N. noctula bats we conducted an experiment in captivity. Twenty two individuals were equipped with thermologgers (iButtons) and placed into cloth bags for two...

Most studies in urban areas focus on green areas within a city given their high value for biodiversity. However, very few have investigated the impact of urbanization on urban green areas at the fringe of cities, as well as long-term data to gather temporal changes. Bats are an interesting taxon to study the impact of urbanization on biodiversity g...

Common Serotine bat Eptesicus serotinus (Schreber, 1774) is a widespread European sedentary bat inhabiting semi-urban and rural areas. The data about skull morphometry of the species is limited and just a few studies show sex dimorphism in skull parameters of the bat. The sex dimorphism in skull morphology of sedentary bats (in size) possibly is th...

All European bats are protected by the EU and Associated Members legal regulations. Being insectivorous and top predators, they can be particularly exposed to persistent organic and inorganic pollutants. It is surprising how little is known about the impact of environmental pollutants on bats from physiological to populational levels. In this study...

An unexpected record of Tadarida teniotis (Rafinesque, 1814) (adult male) was made in Kharkiv city, NE Ukraine. The bat was found in a private flat on the thirteenth floor of a multi-storey building (1970s construction). This new record is much further North than documented from in-hand and acoustic records of this species in the Russian Caucasus -...
Article
Many migratory species have shifted their geographic distribution in response to climate change, yet the underlying mechanisms are poorly understood, particularly for mammals. We hypothesized that generational shifts are underlying the observed colonization of hibernation sites further north in a migratory bat, the common noctule (Nyctalus noctula)...

Urbanization is one of the main drivers of ecological change in the modern world. In most cases, species diversity in urban landscapes is lower than in natural ones; however, some groups of animals are able to exploit and benefit from urban habitat. Pipistrellus kuhlii s.l. is (P. k. lepidus according to recent taxonomic review), a common European...

Bats are volant and highly mobile mammals that could cover up to 2000 km seasonally (one-way migration). But the level of mobility among different roosts sites in a breeding season, and among breeding areas and hibernation sites is poorly studied. With this communication, we aimed to present results of recaptures (51 cases with a distance of 0.5 km...

Movement ecology of bats remains insufficiently studied. Chemiluminescent light tags have been a tool for studying this aspect of bat ecology. However, the potential negative impacts of chemiluminescent tags on the health and lifespan of bats has been poorly investigated. In this study, we tested two methods of light tag attachment: 1) standard met...

North-Eastern part of Ukraine is located near the border of the Steppe zone; forests are fragmented and unevenly distributed here. Our analysis showed that up to 1970th oak forests here were subjected to intensive clear felling. This period was followed by 20 years of decrease in logging intensity, but in the end of 1990th the intensity of clear fe...

Among all volant mammals, bats are the most species-rich group, though they remain still insufficiently studied. Unique bat ecological features (e.g. active flight, high longevity, heterothermy) could impact physiological processes, especially immunological ones, which are the most unrevealed aspect of bat biology currently. Because all European ba...

Developmental studies are fundamental to understanding specialized morphologies. The baculum (os penis) is a heterotopic bone in the glans penis, which is probably subject to sexual selection and may play a role in reproductive isolation between closely related species. In this ongoing study, the pre- and postnatal development of the reproductive o...
