The tundra vole (Alexandromys oeconomus) or root vole is a medium-sized vole found in Northern and Central Europe, Asia, and northwestern North America, including Alaska and northwestern Canada.[2] In the western part of the Netherlands, the tundra vole is a relict from the ice age and has developed into the subspecies Alexandromys oeconomus arenicola.

Description

[edit]

The tundra vole has short ears and a short tail. Its fur is yellowish brown with paler sides and white underparts. It is typically about 18 cm (7.1 in) long with a 4 cm (1.6 in) tail and a weight of about 50 grams (1.8 oz).

Habitat

[edit]

The tundra vole is found in damp tundra or moist meadows, usually near water.

Behaviour and diet

[edit]

This species makes runways through the surface growth in warm weather and tunnels through the snow in winter. It feeds on grasses, sedges and seeds. It is active year-round. It also digs burrows where it stores seeds and roots, especially licorice root, for the winter.

Breeding

[edit]

Female voles have three to six litters of three to nine young in a shallow burrow. The vole population in a given area can vary greatly from year to year.

Subspecies
