Roost switching is closely related to the dawn swarming, serving as a source of information for the choice of the new roost. The main aim of our thesis was to expand the knowledge about this unique social behaviour and the mechanisms behind it, whereas previous findings were mostly anecdotal and lacked further details. Most of the results are based on a maternity colony of Daubenton’s bat (Myotis daubentonii) but data on Leisler’s bats (Nyctalus leisleri) were employed too. Using a combination of different methodological approaches such as passive integrative transponders (PIT-tags) and automatic RFID readers, microsatellite genotyping of individuals, an enzyme immunoassay from bat droppings and an agent-based computational model, we found that: 1) The pattern of dawn swarming differs between sexes and age categories. Juveniles and yearlings mainly swarm around dawn, with no particular pattern, while old females swarm as the main part of the colony during most of the night, with a gradual increase from midnight onwards. This difference may be related to the learning status of the young bats. Old males swarm at least because of their solitary lives. 2) Old females increase their swarming activity during the time when juveniles are capable of flying, in order to guide them within the colony area or to teach them swarming behaviour itself. In addition, old females and juveniles swarm together more often than dyads of adult females only. Kinship is an important factor in the formation of swarming dyads only in youth, towards adulthood the effect of kinship diminishes. 3) Swarming behaviour may be correlated with an elevated cortisol levels as a result of roost switching due to stressor exposure, as is predation or unsuitable microclimatic conditi URL https://opac.crzp.sk/?fn=detailBiblioForm&sid=F806E6B7D49B8C8B146EFDF8458C Báza dát xkni - KNIHY Druh dok.
