Volodymyr Tytar has devoted much of his research to the study of the fauna of unique parts of the world—Chukotka, Kyrgyzstan, Chernobyl, the Black Sea region, and others. He has been interested in various animal taxa, including those of mammals. Focusing on mammal species, he has conducted a number of unique research related to the study of viability and variability of populations under extreme conditions (including radioactive pollution), modelling of the ecological niche and dynamics of their home ranges in the context of climate change. He has paid considerable attention to the research and monitoring of populations of rare species on the basis of citizen science, including the study of the Central Asian population of snow leopards, as well as the long-tailed marmot as their potential prey. The researcher's activity is also related to the development of management plans for wetlands of international importance.
