My research is focussed on ecology, behaviour, distribution and taxonomy of terrestrial vertebrates, mainly bats and their ectoparasites: Coevolution of acoustic systems between bats and moths Interaction between bats and their roost ectoparasites Roost selection in bats with respect to olfactory clues Special ectoparasite avoiding strategies Migration of bats along the river valleys and through the mountain saddles. Automated radiotelemetry system
