Open encyclopedia reference

The forest-steppe marmot (Marmota kastschenkoi) is a rodent species of the marmot genus found in south-central Russia. It lives in wooded forest steppe at an altitude of 180–450 m (590–1,480 ft) in a relatively small region located directly east of the upper Ob River. It has traditionally been considered a subspecies of the similar, more southerly distributed gray marmot (M. baibacina), but was separated mainly due to different diploid numbers.
