“…The later appears to be the most flexible and cold-hardy than the former two species (see also Taake, 1984;Holzhaider and Zahn, 2001). Myotis brandtii and M. alcathoe occurred in greater num bers in Zbójecka Cave, whose surroundings are dominated by deciduous forests, which these two species seem to prefer (Taake, 1984;Niermann et al, 2007;Lučan et al, 2009;Danko et al, 2010).…”

“…The most abundant species, M. daubentonii and either M. brandtii or M. mystacinus, were the same in the Eastern (Bieszczady Mts) and Western Carpathians in Poland and Slovakia (Kaňuch & Krištín 2006;Kurek et al 2008). Apparent rarity of M. alcathoe in these regions (recorded only in BNP), where its preferred habitatold broadleaved forests (Lučan et al 2009) -is overrepresented (Carpathian beechwood), may reflect its local low population density. This species was one of the most abundant in captures over water in the adjacent area of southeast Slovakia, but at lower elevations (100-540 m a.s.l) and mostly in warmer forests, dominated by oaks and beech, on southoriented slopes (Danko et al 2010).…”

In relation to almost completely reduced anthropogenic pressure after 1944 and the consequently low number of present settlements, impoverishment of the bat (Mammalia: Chiroptera) fauna has been suggested for the Western Bieszczady Mountains (Mts), southeast Poland. During a field study in 2009-2011, we recorded 15 bat species within the Bieszczady National Park and 19 in total (i.e. all but one or two expected for the Bieszczady Mts), including a locality at a cave near the park border. At 26 (72%) of 36 localities sampled over water, forest roads and glades, in 278 mist net hours, we captured 159 bats representing 12 species. Species most frequently sampled and most abundant in captures were Myotis brandtii and M. daubentonii (both over 50% of localities and 80% of bats in total). Most of the captured bats were males (73%) and adult individuals (85%). Fifty percent of M. daubentonii (both sexes) and several males of M. brandtii, netted over streams, were soiled with fresh clay, indicating day roosts of these bats were likely located in rocky crevices at river banks. We found bats (six species) or their faeces in 28 (48%) of 58 inspected roosts in buildings. Vespertilio murinus was the most abundant and most frequent species. The same number of species (five) used farm buildings and houses. Most bats found at roosts were adult males either solitary or in two colonies of V. murinus. Despite the high number of species recorded, we confirmed the impoverishment of the attic dwelling species set. Although no church attics, frequently utilized by colonies of Rhinolophus hipposideros and M. myotis in the other Carpathian regions, are present in the Bieszczady National Park, local buildings as a limited source of roosting site are important for bat conservation.

“…It was shown that for temperate bats of aerial hawkers, the food availability in October decreases to one quarter or even one tenth in comparison to its greatest abundance in July and August (Speakman and Rowland 1999). In fact, bats with the early swarming peak of activity forage mainly on flying prey (Flavin et al 2001;Pithartová 2007;Lučan et al 2009;Krüger et al 2012;Andreas et al 2012b;Nissen et al 2013). …”

Activity pattern and fat accumulation strategy of the Natterer’s bat (Vespertilionidae, Chiroptera) swarming population indicate the exact time of male mating effort

Studies concerning bat autumn swarming behavior suggest that the main purpose of this phenomenon is mating. However, the process of fat accumulation is crucial for surviving winter, and it seems to be in clear conflict with a need to strive for the opportunity to mate prior to hibernation. Investment in one activity limits the other one creating a trade-off between them. The aim of our study was to describe the activity pattern of each sex-age group (adult males, adult females, subadults) of the Natterer's bat during swarming period and to investigate the fat accumulation process of adult males in the context of their reproductive strategy. Bats were captured by mist nets at the swarming site fortnightly from the early August until the late November. The age, sex, reproductive status, and body condition index (mass to forearm ratio, BCI) were recorded. The activity peak of both sexes, adults, and subadults was observed in the late September. That time in season, BCI of adult males was the lowest, and there was no correlation between the hour of an adult male capture and its BCI value within one night (r s = 0.23; p = 0.157). Such correlation was observed later in the season (early October: r s = 0.44; p = 0.020; late October: r s = 0.48; p = 0.002). A negative correlation between adult males' BCI and proportion of adult females was found (r = 0.44; p = 0.000). We conclude that the activity peak of females is likely to be responsible for the effort of the mating behavior of the males, which is reflected by their low condition index. We suggest that the gleaning foraging strategy of Natterer's bat allows the males to postpone their fat accumulation until just before hibernation.
