It inhabits northern forests, shrublands and tundra, remaining active throughout winter beneath the snow. Nests are placed in short burrows or beneath rocks and roots. Berries are prominent in its diet, supplemented by other plant parts, fungi, mosses, lichens and occasional insects. Females produce two or three litters in a season, with four to nine young per litter. (Wikipedia, general species account)
