Data were collected in April-September (1999 using mist-netting and bat-detectors (n ¼ 209 samplings) in Slovakia (n ¼ 160 sites). For the habitat description, 17 environmental variables that characterised the sampling site, tree-species composition and general character of surrounding forest were selected. In study sites, altogether 93% of Slovak chiropterofauna species were recorded but only 16 species (2466 individuals) were recorded in more than 5% of samplings. The most common and frequent species were Myotis mystacinus (frequency of occurrence ¼ 57%, species dominance ¼ 12%) and Myotis myotis (44%, 10%), followed by Barbastella barbastellus (32%, 6%), Plecotus auritus (32%, 6%), Nyctalus noctula (31%, 9%) and Myotis brandtii (31%, 7%). Of the tested environmental variables used in CCA analysis, 13 had significant influence on the species' presence. On the base of gradients in ordination analysis, there were two main groups of species. In the first ''true'' forest bats group the tree-dwelling and gleaning species Myotis bechsteinii, Myotis nattereri and P. auritus dominated. Their occurrence was connected mainly with old forests of natural tree-species composition. The second group comprised species, which foraged in more open space or along the forest edge (with the farmland) and avoided closed interior (particularly Eptesicus serotinus, N. noctula, Nyctalus leisleri, Pipistrellus pipistrellus). The presence of mountain species Eptesicus nilssonii and Vespertilio murinus was associated mainly with dominance of spruce. Suggested predictive modelling of species composition in forest bat assemblages in conditions of natural forests can help in nature conservation.

occurred only in southern parts of the country and in the Pieniny National Park, with a small population
located in the Aksamitka cave. For a long period of time, this site represented the northern edge of the regular distribution of this species. Over the past 39 years no records of its presence were found. However, in autumn 2014 two individuals were mist-netted in the front of the Aksamitka cave and bat-detector records from two other locations in the region (Spišská Magura Mts. and Poprad) confirmed the return of the species to the northern part of Slovakia. Questions related to the conservation of this species and the implications of the human impact with respect to the cave are subsequently discussed.

It is in accordance with considerable increasing of the species occurrence in urban habitats during the last years. The first roost of Pipistrellus pygmaeus in Slovakia was found in a prefab house. Few individuals were mixed with Pipistrellus pipistrellus during spring migrating period. Subsequently, the first nursery of P. pygmaeus in Slovakia was confirmed in the similar urban habitat. Conservation activities in prefab buildings should consider this fact.

The use of ultrasound detectors has revolutionized the field studies of bats, but fast spreading methods are often not properly used in the beginning. We discuss the pitfalls of comparing bat detector data from habitats with different availability. Our examples show that in many situations smaller habitats may be assessed as preferred habitats and extensive habitats are regarded as “avoided”, in spite of the fact that the animal spends most of the time there. We conclude that it is important to consider also habitat availability, habitat function and prey availability to correctly evaluate habitat preference. We find that in habitat use studies in bats, the time spent in a habitat is probably a more objective measure for habitat preference than relative flight activity. Improper interpretation of the data from acoustic studies may lead to serious mistakes in conservation management of bat populations.

Six different forest habitat types were studied: oak forest, beech forest, stream, road, forest edge and open area within the forest. Bats were detected in all habitats. Sixteen species were found. habitats were used differently by the individual species. The highest species diversity was observed in the forest interior. The first peak of flight activity was after sunset which then declined and was relatively even through the night until the second peak before sunrise, which was recorded in the forest interior, open area and on the road. The highest flight activity was recorded at the forest edge, forest stream and in open area. Recorded activity was 3× lower in the oak forest interior compared to the forest edge, but if the extent of the forests is considered, forest interior is the most important foraging habitat. Consequently future forest management should consider the needs of this endangered group of animals.

Annual observations from one bridge in Nitra showed high use of this habitat type. Also incidental findings from five other localities are presented. In Nitra 1533 records of N. noctula
were obtained during 28 surveys. Noctules used the bridge drainpipes and other crevices all year round except the summer months. The highest number was recorded in November (164 individuals) when groups of up to 60 individuals were present. In autumn mating aggregations accumulated (3–9 individuals). The bridge was also used by solitary M. myotis males (64 records). In autumn mating groups of 2–3 M. myotis were also present. Big aggregations of N. noctula (maximum 457 individuals) were also found in a bridge in Ružomberok. In addition, two other localities with bridge roosts of M. daubentonii were found.

Using the ultrasound bat detector, the flight activity of noctules was observed during whole winter period (n=28 surveys). Intensity of relative flight activity positively correlated with average day temperature. Noctules were often flying in temperatures between 0 and –5 °C. In the coolest days, when average day temperature decreased to more than –10 °C, no bat passes were recorded. Altogether, 27 noctule roosts were found, mostly located in the roof attics. There was no preference in the height of the shelter and bats preferred less western, possibly southern orientation of the
roosts. It appears that the selection of the roost depends mainly on the general accessibility of the shelters in prefabs. Recorded two movements of banded bats, concerning the study area, broaden the knowledge about the residence and short movements of males during the year and migrating site ﬁ delity in females of the noctules in Slovakia. Predation of bats by the long-eared owl (Asio otus) was observed there.
