ABSTRAKT: Badania prowadzono w lasach Parku Krajobrazowego Międzyrzecza Warty i Widawki (centralna Polska), gdzie w roku 2014 rozwieszono 125 drewnianych skrzynek dla nietoperzy typu Strat-mann oraz 11 schronów trocinobetonowych. W kolejnych latach (2014-2021) kontrolowano skrzynki ob-serwując ich stopniowe zasiedlanie. W drewnianych skrzynkach nie...

In the years 2004-2018, data on bats wintering in 9 sites of the Northern Group of the Soviet Army (PGWAR) stationed in the years 1945-1993 in Poland were obtained. A total of at least 11 bat species were found: greater mouse-eared bat Myotis myotis, Natterer's bat M. nattereri, Daubenton's bat M. daubentonii, Bechstein's bat M. bechsteinii, whiske...

Warmer winters may lead to changes in the hibernation behaviour of bats, such as the barbastelle Barbastella barbastellus, which prefers to hibernate at low temperatures. The species is also known for its large annual fluctuations in the number of wintering individuals, so inference about population trends should be based on long-term data. Prior t...

ABSTRACT: In this article new information concerning migrations of bats from summer roost to hibernation and autumn swarming place in Szachownica Cave are presented. This cave is the fourth most important wintering place of bats in Poland in terms of quantity of hibernating individuals. It is also very important as swarming place. Based on the re-c...

Temperate-zone bat species store fat in autumn prior to hibernation. The likelihood of surviving until the next breeding season largely depends on the resources accumulated. In addition, autumn is also a period of mating behaviour known as swarming, which is energetically expensive and may affect the body condition of bats in different ways. Our go...

In autumn, the activity of bats in the surroundings of underground sites increases rapidly and is mainly associated with mating behavior and/or arrival for hibernation. Bats were caught at the entrances of 14 caves in the Częstochowa Upland and at one cave in the Wieluń Upland. Between 1998 and 2016 3,686 individuals of 14 bat species were caught....

The Szachownica cave (Krakow-Wielun Upland, Poland) is one of the four largest wintering shelters for bats in Poland. Since the cessation of limestone mining, the number of wintering bats increased from 300 to more than 2,900 individuals. In recent years, there has been seen a gradual worsening of the cave structure due to frost destruction, which...

Szachownica Cave located in the Wieluń Upland, in the north Jura is one of the five largest bat wintering sites in Poland. It is protected by the reserve conservation and it is included in the Natura 2000. It is an object where bats are monitored continuously for 37 years - twice in each winter season: at the end of January and at the early March....

The paper presents breeding records of the barbastelle (Barbastella barbastellus) from the whole current territory of Poland, both published data from papers and conference abstracts, and unpublished data collected by the authors. Up to 1999, known locations of maternity colonies and sites where young or lactating females had been caught, were assi...

On January 10, 2015 the annual bat census was conducted in the Nietoperek Bat Nature Reserve (The Międzyrzecz Fortification Region). The bat species identification and the bat rings reading were executed without disturbing the animals. Both single and clustered hibernating bats were recorded. The whiskered bat Myotis mystacinus and Brandt’s bat M....

In June 2010 and 2012 two nursery roosts of whiskered bat Myotis mystacinus were found in central Poland (Południowowielkopolska Lowland). Both female colonies occupied crevices under the sills of roof gutter of house. New records enriched knowledge about shelters of breeding colonies of the whiskered bat in Poland.

Sites included in Natura 2000 „Forty Modlińskie” (PLH140020) together with recently discovered "Baszta Michałowska" are currently the biggest in the Mazovia region and one of the biggest in Poland bat hibernacula. However it was unexpected that there was a big, completely undiscovered fort, that could possibly be an important bat winter roost. Duri...

Single hibernating males of Myotis alcathoe were recorded in caves and mining adits at four localities in the Beskid Wyspowy Mts, Western Bieszczady Mts, Western Sudety Mts and Roztocze Upland. These are the first records of wintering individuals of the species in Poland and some of the first in Central Europe. Characters are described that may be...

The paper presents the results of winter bats' censuses in standalone bunkers of Międzyrzecki Fortified Front (MFF) not connected with the Central Part (CS) of underground system of corridors and stations in western Poland. During the years 2005-2012 47 objects were controlled. At least 12 bats’ species (3536 determined individuals) hibernated in s...

The data about bat mortality at wind farms were collected from the years 2007-2011 in five regions of Poland. The cases of mortality were confirmed for 7 bat species: Vespertilio murinus, Eptesicus nilssonii, Eptesicus serotinus, Pipistrellus pipistrellus, Pipistrellus pygmaeus, Pipistrellus nathusii and Nyctalus noctula. 5 species were recorded in...

A bat census in the years 1981–2010 (repeated twice during each hibernation period in January and March) showed upward trends in many populations of bats hibernating in the Szachownica Cave (central Poland). Total numbers of the bat assemblage, which consisted of 11 species, increased within the study period from 178 to 1477 individuals in the firs...
Article
The presence of bats in the diet of tawny owls inhabiting the entrance parts of a large bat hibernation site in central Poland was compared in two periods. In the years 1985-1988 the median total number of hibernating bats per survey (522) was nearly 3 times lower than in the years 2002-2008 (1455). Along this trend the share of bats in tawny owls'...

The authors present results of winter bat censuses carried out in 8 caves of the Wieluń Upland between 1982-2004. Regular counts (two in each hibernation period) show direct changes in dominance structure and numbers of particular bat species. The numbers of Barbastella barbastellus and total numbers of a bat community significantly increased in Sz...
