Golenko A.S., Dzeverin I.I. 2007. Body mass dynamics and activity of serotine bats (Eptesicus serotinus) hibernating under laboratory conditions. ­ Plecotus et al. 10: 14­20. Most serotines come to the Rehabilitation Bat Center attached to Kiev Zoo in cold season (Fig. 1). In winter 2006 we studied hibernation of eight individuals (six males, two females) there. The animals were divided into four groups and lodged in terrariums with two bat boxes each. For monitoring bat activities we laid out paper strips on the bottom of the terrarium.

Serotines prefered to hibernate singly, and they could manage without access to drinking water. The main factors causing arousal were disturbance through handling or probably fluctuations of atmospheric pressure. Relationship between activity level of the animals and ambient temperature has not been confirmed (N = 260 records, Spirman's correlation coefficient Rs = 0.07, p = 0.25). Ambiebt temperature influenced behaviour of the bats only in those cases when it changed rapidly or came out of the limits from 2 to 14єC. Activity was higher in more fattened individuals, and they demonstrated the higher bodyweight loss (Fig. 2). From 19 January to 30 March 2006 those individuals that had surplus weight (34.0­46.2 g) lost up to 24% of their initial body mass, while normally fattened (21.3­25.5 g) and emaciated (19.0­19.4 g) individuals lost only 1­6%.
