This analysis reveals the distribution of field voles and habitat types in western Siberia, suggesting environmental factors influence their abundance.
Based on material collected in the second half of summer for the period from 1954 to 2016 in the lowland and mountainous parts of western Siberia, the distribution of the Field vole is analyzed in zonal and provincial aspects. Cluster analysis of a matrix of the similarity coefficients of abundance indicators allowed for a habitat classification to be compiled based on the degree of favorability of environmental conditions for the study species. There are four types of conditions: optimal, subpessimal, pessimal, and extreme, the latter where no field voles are found. Based on the classification, the spatial heterogeneity of the abundance of the species is linked to the influence of environmental factors and their combinations (regimes).
