Abstract

Population structure, fecundity and participation in breeding of females of different age, feeding trends and fat condition of sable were studied under the conditions of the cold climate in the spurs of the Verkhoyansk mountain ridge. A relatively simple age structure and rapid alternation of generations in the population, increased mortality of mature age females and abundance of junior age cohorts in the sable stock, larger mean value fecundity were determined. Sables with low fat reserves made up over two thirds of the population. A change in their fat condition depended on the consumption level of the animal food items. In some years seeds of the mountain pine were more important as a feed-stuff. Females of the reproductive age had the least fat reserves that may be regarded as one of the reasons of their increased death-rate.
