Abstrakt: The paper shows that, in the past centuries, the anthropogenic transformation of the landscape against the climatic changes in Western Siberia favoured migration of one species of vertebrata and reduced areas of others, but with an obvious positive balance. Over the past 400 years, only 12 species of vertebrata (8 species of mammals and 4 species of birds) became extinct in Tyumen region, whereas 57 new species emerged (13 species of mammals and 27 species of birds). It is stated that the high rates of dynamics of fauna in Tyumen region fall within the last 50 years, and the highest of them account for the last 15 years, which primarily corresponds to the current trend of strengthening of continentality of the regional climate (due to the change of zonal circulation of air masses to meridional circulation) against the global warming in the north of the Northern Hemisphere of Earth because of the change of the axis of its rotation to the plane of the ecliptic.
