Abstract
The biotope distribution of Myodes rutilus in the zonal and provincial aspects based on materials collected in the second half of summer for the period from 1954 to 2015 in the plain and mountains of Western Siberia was analyzed. The previously noted preference for plain and mountain forests containing dark coniferous species within the taiga zone of the plain, the Northeast Altai and the Kuznetsk Alatau was confirmed. On the basis of cluster analysis of the matrix of similarity of coefficients of abundance indices the classification of habitats of northern red-backed vole by the degree of optimality of environmental conditions (favorability) for this species was made. The subtypes of habitats characterize an abundance to a lesser extent than types. According to the classification and the structural graph the dependence of abundance is tracked on the zonal-subzonal affiliation of habitats, provincial differences in mountain areas, and also on the vegetation types, altitude zonation in the mountains, the degree of afforestation, the composition of forest-forming species, flooding, swampiness and plowing. The highest correlation between the distribution of the northern red-backed vole and habitats in Western Siberia is traced to warmth and humidity (zoning and subzoning on the plains and altitudinal belts in the mountains). Our research on the distribution of Myodes rutilus clarifies the results of the analysis conducted by previous researchers and gives a more detailed picture of its distribution in habitats.
