An Ecologically Destabilized Environment: Its Effect on Small-Mammal Populations

Characteristics of the small-mammal populations inhabiting forest biocenoses in the Middle Ural state reserves have been analyzed over in the period from 1987 to 2002. During this period, the habitats of these animals were considerably destabilized due to windfalls and fires. The environmental chara...

Description
Summary:Characteristics of the small-mammal populations inhabiting forest biocenoses in the Middle Ural state reserves have been analyzed over in the period from 1987 to 2002. During this period, the habitats of these animals were considerably destabilized due to windfalls and fires. The environmental characteristics of animal microhabitats at different stages of environment destabilization have been described quantitatively. Changes in the long-term cycles of the population dynamics of the dominant forest vole species caused by the destabilizing factors have been found. Redistribution of species dominance with respect to abundance has been demonstrated.[PUBLICATION ABSTRACT]
