Tundra Vole (Microtus oeconomus)

Description

The Tundra vole, scientifically known as Microtus oeconomus, is a medium-sized vole that belongs to the rodent family. This species is characterized by its compact body, short legs, and a relatively short tail. Tundra voles typically weigh between 20 to 40 grams and have a body length of approximately 10 to 15 centimeters. Their fur is dense and varies in color from brown to gray, providing effective camouflage in their natural habitats.

Appearance

One of the distinguishing features of the Tundra vole is its compact and robust build, which sets it apart from similar species. Its fur is well-suited for the cold climates it inhabits, providing insulation and protection from the harsh environmental conditions. The Tundra vole’s short tail and small ears are also notable physical characteristics that aid in its identification.

Distribution

The Tundra vole is primarily found in Northern and Central Europe, as well as in Asia and northwestern North America, including regions of Alaska and northwestern Canada. This species exhibits a notable presence in the tundra ecosystems of these regions, thriving in the unique environmental conditions characterized by cold temperatures and limited vegetation.

Habitat Preferences

Tundra voles are well-adapted to thrive in tundra ecosystems, including damp tundra, moist meadows, and areas with abundant cover. These habitats provide the necessary resources for their survival, including suitable vegetation for foraging and building runways. The Tundra vole’s ability to exploit a variety of habitats within the tundra ecosystem reflects its resilience and adaptability to diverse environmental conditions.

Overall, the Tundra vole’s presence in these regions contributes to the intricate balance of the tundra ecosystem, making it an essential component of the local biodiversity.
