“…The lowest number of injuries should occur in Daubenton’s bats, who most often hunt over open waters without vegetation, where there are few obstacles. Insects caught over water dominate in their diet [27, 28]. If necessary, Daubenton’s bats can change their feeding tactics, for example, they can collect their prey [29] or hunt in the forest and over wet meadows [30].…”

Bat wings are characterized by high endurance, and these mammals have developed a number of adaptations that protect them from falling into obstacles and potential injuries. However, in bat populations, there are individuals with visible fresh or healed injuries to the flight–enabling body parts. The aim of this research was to determine the differences in the occurrence of wing membrane damages among species of bats that differ in ecology and behavior. The study was conducted in southern and western Poland in the years 2000–2016 and included 3,525 individuals of six species: lesser horseshoe bat Rhinolopus hipposideros , Daubenton’s bat Myotis daubentonii , Natterer’s bat Myotis nattereri , greater mouse–eared bat Myotis myotis , western barbastelle Barbastella barbastellus , and brown long–eared bat Plecotus auritus . In all, 2.9% of the bats studied showed damage to the flight–enabling body parts. Natterer’s bat was the species with the highest number of injured individuals (21.74%). The lowest number of injured individuals (0.3%) was found in the brown long–eared bat. The most frequently observed type of damage was loss of an edge of the wing membrane (29.3%). The bat species studied differed significantly in the occurrence and location of flight enabling body parts damages. Certain behavioral and ecological factors like foraging mode, foraging habitats and habitat types of bat species determine the number of wing and tail membrane damages.

“…Despite their similar life history, the two species differ with respect to foraging strategy and activity pattern during the hibernation period. Daubenton's bats hunt above water, and there is no evidence for foraging during winter (Flavin, Biggane, Shiel, Smiddy, & Fairley, 2001;Kokurewicz, 2004;Siemers, Dietz, Nill, & Schnitzler, 2001). In contrast, Natterer's bats glean arthropods from surfaces (Andreas, Reiter, & Benda, 2012;Siemers, Kriner, Kaipf, Simon, & Greif, 2012;Siemers & Schnitzler, 2000) and radio-tracking data suggest that they feed during hibernation period (Hope et al, 2014).…”

Long‐lived animals with a low annual reproductive output need a long time to recover from population crashes and are, thus, likely to face high extinction risk, if the current global environmental change will increase mortality rates. To aid conservation of those species, knowledge on the variability of mortality rates is essential. Unfortunately, however, individual‐based multiyear data sets that are required for that have only rarely been collected for free‐ranging long‐lived mammals. Here, we used a five‐year data set comprising activity data of 1,445 RFID‐tagged individuals of two long‐lived temperate zone bat species, Natterer's bats ( Myotis nattereri ) and Daubenton's bats ( Myotis daubentonii ), at their joint hibernaculum. Both species are listed as being of high conservation interest by the European Habitats Directive. Applying mixed‐effects logistic regression, we explored seasonal survival differences in these two species which differ in foraging strategy and phenology. In both species, survival over the first winter of an individual's life was much lower than survival over subsequent winters. Focussing on adults only, seasonal survival patterns were largely consistent with higher winter and lower summer survival but varied in its level across years in both species. Our analyses, furthermore, highlight the importance of species‐specific time periods for survival. Daubenton's bats showed a much stronger difference in survival between the two seasons than Natterer's bats. In one exceptional winter, the population of Natterer's bats crashed, while the survival of Daubenton's bats declined only moderately. While our results confirm the general seasonal survival pattern typical for hibernating mammals with higher winter than summer survival, they also show that this pattern can be reversed under particular conditions. Overall, our study points toward a high importance of specific time periods for population dynamics and suggests species‐, population‐, and age class‐specific responses to global climate change.
