The bat fauna of Albania, a country located in Balkan glacial refugium and Mediterranean biodiversity hotspot, has remained poorly studied although as many 21 species representatives three complexes had been reported before 2003. It was expected that several new would be added to the country’s list fauna, not only due their occurrence adjacent regions but splitting already known taxa into sibling discovery new, cryptic species. Altogether, we recorded 32 including all those previously (21)...

Abstract In temperate regions, winter is characterized by cold temperatures and low food availability. Heterothermic animals can bridge this period entering a state of torpor decreased body temperature reduced metabolic rate. Hibernation site choice crucial since conditions in the hibernaculum will impact torpor. We analysed temperature-dependent hibernation use Barbastella barbastellus . Bats were monitored an underground system (1999–2019) standalone bunkers (2007–2019) Western Poland....

"Lunar phobia" in bats has been widely discussed since its description tropical 1978. The phenomenon frequently contested and supported was first reported European 2020. Our study seeks to clarify the debate by describing relationship between activity of selected swarming vespertilionid (Family: Vespertilionidae) moonlight levels. To verify a potential connection latter, dataset analysed respect estimated illumination. Moonlight estimates were based on geographical location several lunar...

Since its description in 2001 Alcathoe's myotis (Myotis alcathoe) was recorded from several locations across Europe. Here we describe the first records of this species Germany, Poland, Albania, and European part Turkey, including northernmost locality central Germany (51°23′N, 11°01′E). Compilation all up-to-date shows that M. alcathoe has a wide distribution although it seems to be rare at most places. The habitats where bat are natural, moist deciduous forests with old trees water streams...

We present the results of a study which describes relationship between western barbastelle Barbastella barbastellus highly specialised moth predator, and its prey-moths genus Orthosia, another selective animal known to converge around dominant producer pollen nectar in early spring-willow trees Salix sp. In order describe this trophic relationship, we conducted acoustic recordings at five paired sites (willow/control tree) proximity hibernation (Natura 2000: PLH080003 PLH200014) beginning...

Natural forest disturbances are increasingly common due to ongoing climate changes but their impact on most of organisms is poorly studied. Here we investigate the link between spruce bark beetle Ips typographus outbreak in 2011–2017 Białowieża Primeval Forest (Poland) and activity a bat conservation concern: western barbastelle Barbastella barbastellus. Bats were surveyed by recording ultrasound signals 8 transects (3 km each) mixed coniferous deciduous with different share Norway spruce....

Alek Rachwald, Tim Bradford, Zbigniew Borowski, and Paul A. Racey (2016) The habitat preferences of the soprano pipistrelle Pipistrellus pygmaeus common pipistrellus living in sympatry, were investigated north east Scotland, using bat detector transects. Bat flight, foraging social activity natural birch woodland was compared with that managed non-native coniferous woodland. Each area consists riparian habitat, meadow-forest ecotone dense forest. bats highest then meadow, lowest P. more...

Our study explores the role of bats as reservoirs coronaviruses. We conducted virological screening hibernating in military bunkers at Natura 2000 site "Nietoperek" Western Poland collecting oral and anal swab samples from 138 across six species to apply a combination pan-coronavirus SARS-CoV-2 specific PCR assays. Only one tested positive for coronavirus. No was detected any samples. The low prevalence coronavirus studied colony contrasts with higher rates found other regions may be...

Abstract The occurrence of the Common pipistrelle in bat fauna Białowieża Primeval Forest was expected, because taxon P. pipistrellus previously comprised two separate species. Earlier observations area can mostly be counted for by new species Soprano pipistrelle, which is considered equally widely distributed area. In this study, we were able to record and distinguish several passes means detecting techniques. Bats found locations, first one being village, whereas second woodland close...

Białowieża Primeval Forest (BPF, approx. 1700 km2) is an important forest area in Europe from the point of view protection natural diversity. BPF covered with old mixed tree stands mostly origin. Norway spruce a species and covers 27% its area. Between 2012 2017 large outbreak bark beetle Ips typographus (Linnaeus, 1758) took place forest, which transformed left many dead standing trees. At that time salvage logging had begun but was stopped due to protests by scientists activists for legal...

We studied the occupation of crevice-type roosting boxes developed especially for barbastelle bats Barbastella barbastellus (Schreber, 1774). Some 290 were installed (in groups five) in six study areas located Poland forests different tree species composition. Colonization took place first summer season after installation. Two years installation, a high rate occupancy was recorded (up to 100 % boxes, depending on area). The total number involved 478, 72 which target species. Occupancy rates...

This study concerns comparison of bat activity in five mixed coniferous forest areas, exposed to different degree air pollution. Forest age at every plot was 70-100 years. The main census method the detection ultrasound signals along line transects. A significant difference found diversity and between these areas. Median flight varied 21 flights/1 control (Biebrza Valley) 1 flight/1 (Upper Silesia). largest less disturbed polluted forests Białowieża Primeval Biebrza Valley, lowest recorded...

Abstract A Western Barbastelle, Barbastella barbastellus (Chiroptera: Vespertilionidae , Schreber, 1774), was observed to inhabit ‘crevice’ bat boxes very late in the year. In November 2016, two out of three study areas, a small number Barbastelle specimens, five individuals and one individual respectively, were inhabiting at night temperatures below zero with snow cover. The occurrence this species summer-type hiding places during winter weather conditions has not been reported previously Poland.
