Bendová, Barbora ; Andreas, Michal (advisor) ; Bartonička, Tomáš (referee)
In 2012 it was observed foraging ecology of the three males of greater mouse-eared bat (Myotis myotis), inhabiting individual roosts in the interior of road bridge near Bernartice, and the nearest nursery colony of the same species in the village Senožaty (district Pelhřimov). In the period April to September in Senožaty were made 14 collections at intervals of approximately 14 days and in the bridge near Bernartice at similar intervals were made 8 collections from each male in the period from May to September. From each collection were subsequently been analyzed 20 samples (pellets) by the traditional method of preparation of faeces. Overall it was from all the bats analyzed 760 samples, of which 280 from the nursery colony and 480 from males. Based on the analysis was found diet composition of individual bats and of the colony, where the overall character of the trophic niche of the greater mouse-eared bat, seasonal dynamics in it's diet composition, sex differences and individual differences between males were observed. From a point of view of it's hunting strategy the greater mouse-eared bat showed itself as a ground gleaner, in whose diet were dominated larger Coleoptera, of which the predominant component were large, flightless, mostly forest Carabidae, adding medium and smaller species of...
