Abstract

Successions of a rodent population have been investigated in the forest biocenoses of the Visim Nature Biosphere Reserve (Sverdlovsk oblast, Middle Ural) after a catastrophic windfall and two fires. Differences in the values of the total abundance of rodents and their ratio in the community before natural catastrophes and at different postcatastrophic demutational succession stages are revealed. Structural alterations in a rodent population are associated with different responses of the species to the anemogenic and pyrogenic transformation of their microhabitat environment and can be considered compensatory mechanisms maintaining the sustainability of small mammal communities under the impact of natural catastrophic factors.
