The death of bats due to anthropogenic factors in the region of the Black Sea Biosphere Reserve
2018
Z. Selyunina
The complete checklist of bat species of the Black Sea Biosphere Reserve contains 12 species. However, during recent years, only 9 species have been sighted. Most of the species prefer anthropogenic habitats such as buildings and artificial plantings. Over the past 20 years, only 12 % of observations of bats occurred in natural ecosystems. Nevertheless, the advantages of inhabiting anthropogenic habitats contrast with the increase of risks for existence under such conditions. In recent years, the studied dead animals belonged to 8 species. Among the factors that causes the death of bats are the following: transport (8 %), domestic predators and intentional killing by humans (42 %), repair of buildings, electric and heating communications (25 %), interruption of winter hibernation, hunger, hypothermia (16,7 %), and sanitary research (8,3 %). The adaptive value of synanthropization should be considered in relation to the emergence of new risks and their volumes.
