POPULATION OF SMALL MAMMALS IN SOME BIOTOPES OF THE TIGIREK RESERVE IN 2016
The purpose of the study was to analyze species composition and abundance of small mammals in four low-mountain habitats in the protective zone of the Tigirek Reserve and transformation of this characteristics during the study period. Sempling was carried out on July 4 - August 25, 2016. Species richness was 14-15 species in different habitats, 8 - in slope steppe. The minimum of species richness was noted in the first decade of August, and in chern taiga, becides, - in first ten days of July. In all studied habitats, Sorex araneus and S. minutus prevailed, and in chern taiga - Sorex araneus, S. isodon and Myodes rutilus. In some decades, other species dominated to. In separate decades the combination of dominants included other species. The structure of the population of small mammals has changed as the duration of the work increasesd. During the first 38 days, the most original was the population of chern taiga; as the period of work increased further, its similarity to the population of shrubs increased, and the most original appeared to be the population of steppe.
