EVOLUTIONARY AND ECOLOGICAL ASPECTS OF GENETIC VARIABILITY IN POPULATIONS OF SICISTA BETULINA (RODENTIA, DIPODOIDEA) FROM VALDAI HILLS

Chromosomal (routine, C-banding) and molecular (cytb) data for Sicista of the betulina group from the northern (Valdai National Park), central (the main watershed of East European Plain) and southeast (Upper Volga Basin) parts of Valdai and, for comparison, from the Moscow and Central Chernozem regions are presented and generalized. The birch mice from Valdai and the Moscow area belonging to the 32-chromosomal S. betulina, and that from the Central Chernozem area belonging to S. strandi (2n = 44) are confirmed.
