On sexual dimorphism in the winter diet of the sable (Martes zibellina L.)

The contents of the digestive tract in sables (Martes zibellina L.) of known sex and age from the Middle Kolyma basin were examined to assess the winter diet in general and the frequencies of particular types of food in different sex and age groups of these animals. No statistically significant sex-related differences in the diet were revealed. This is probably explained by a considerable overlap of size and weight parameters between male and female Kolyma sables, due to which probable differences in their diets are leveled off.
