Abstract
His study analyzes the present distribution of the Tuva mountain voles based on literary data, museum collections, and the own materials. The bioclimatic model of potential species distribution has been constructed using 25 localities which were identified as the presence of Tuva mountain vole in the territory of Russia and Mongolia. It is shown that the species range of the Tuva voles consists of three large isolated parts: the northern one, located mainly in Khakassia; southern, located in Tuva and the adjacent territory of Mongolia; small area on the northern shore of Lake Khuvsgul in Mongolia. The examination of habitats of the Tuva mountain voles in the territory of Khakassia showed that in recent decades there has been a significant decrease in the number of inhabited sites, which indicates a significant decline of population and intensification of fragmentation of the northern part of the range of the Tuva mountain vole.
