We study different aspects of animal behaviour, ecology, ecophysiology, life-history, ecomorphology and phylogeny. We use wide range of research techniques: Field studies, laboratory rearing, computer analyses of animal behaviour and morphology, different laboratory techniques including molecular ones, etc. However, our research is problem-oriented, so we do not feel restricted to a specific method. General conclusions, for example, testing of hypotheses in an ecological evolutionary framework, as well as practical aspects of conservation biology are results of our work.
