Population structure and morphophysiological characteristics of the red-backed vole in the south of the Tyumen region

Promotorova Elena Yurievna  (candidate of Biological Sciences, Associate Professor, Tyumen State University)

The paper presents the results of studies of the spatial structure and morphophysiological parameters of the population of the red vole, living in areas of the South of the Tyumen region with different levels of anthropogenic impact. 16000 trap – days were worked out and 486 individuals of red voles were caught. It is revealed that with increasing anthropogenic load there is a decrease in the total abundance, indices of population and aggregation; there was an increase in the indices of the heart, kidneys (in females) and liver (in males) and a decrease in the indices of the spleen and adrenal glands; there is a change in the sex ratio in the direction of increasing the number of females.

Keywords:red-backed vole, anthropogenic forcing, the spatial structure, the morphological and physiological indexes.
