DYNAMICS OF SPATIAL DISTRIBUTION OF THE ABUNDANCE OF BANK VOLE (CLETHRIONOMYS GLAREOLUS Schreber, 1780) UNDER CHANGING BIOTOPIC CONDITIONS ON RESERVED TERRITORY OF THE MIDDLE URAL
The bank vole is widely used as the model species for solving many environmental problems. The study of the spatial distribution of the abundance of this species under changing biotopic conditions on territory of the Visim State Natural Biosphere Reserve revealed the “malfunction” in long-term population dynamics, expressed in the violation of the alternation of individual phases of the cycle. As one of the main reasons for the observed violations, the consequences of natural catastrophic effects that have changed the habitats of small mammals are considered.
