Amur lemming

The Amur lemming is rusty brown with a underbelly. A thin, dark dorsal stripe runs the length of the body. It often has a thicker black stripe running across the dorsal neck, however this may be less pronounced in some individuals. The Amur lemming is typically smaller than other true lemmings, though individual size varies based on locality and season of birth. The Amur lemming lives further south than its congeners. Specimens have been collected from the Amur region and from southern Yakutia. The Amur lemming inhabits marshes, shrublands, tundra, and larch forests. It feeds on mosses (particularly Dicranum, Drepanocladus, and Hyloomnium mosses), heathers, cotton, grasses, and insects. Females can birth 2-4 litters per year with 3-9 young in each litter.
