Population [top]

Population: Data on population size are lacking, but as in most rodent species populations fluctuate. Severe springs may cause population reduction; heavy rains and floods cause short-distance migrations.
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: Inhabits waterlogged tundra, sedge and Sphagnum marshes, waterlogged banks; avoids anthropogenic landscapes. Lives in colonies with shallow burrows in dry areas. Nest chambers are usually sited on hillocks, on the ground, or on shrub branches. The species feeds on sedges, leaves and stalks in summer and roots in winter. Reproduction occurs from May to August, in favourable years from March til October. Females that have overwintered give birth to up to 3 litters per year. In the Urals fecundity is lower than in Yakutia.
