The ecology of quaternary mammals in the Urals

Special aspects of solving certain key problems in the ecology of Quaternary mammals using materials from the Ural region are considered. Possibilities and limitations accounted for by specific features of the region are analyzed. The nature of “mixed” (mammoth, tundra-steppe, hyperborean) faunas and their diversity are considered in the context of questions related to trends in the dynamics of range boundaries and relative abundance of different mammal species during the Late Pleistocene and Holocene.
