Anderson’s Red-backed Vole

Common Name: Anderson’s Red-backed Vole
Scientific Name: Myodes andersoni

Habitat

Anderson’s Red-backed Vole is primarily found in the boreal forests of North America, particularly in parts of Alaska and Canada. This species prefers moist, dense undergrowth areas and often inhabits regions near streams or wetlands. The cool, temperate climate and rich vegetation of these habitats provide the essential cover and food sources for survival.

Physical Characteristics

Anderson’s Red-backed Vole is a small rodent, typically measuring between 10 to 12 cm in body length with a tail length of about 6 to 8 cm. They have soft, dense fur that is a rich reddish-brown color on the back and a lighter, grayish hue on the belly. Their rounded shape, short legs, and small ears contribute to their compact appearance. One distinctive feature is their tufted tail, which aids in balance as they navigate through dense underbrush.

Behavior

This species is primarily nocturnal, exhibiting peak activity during the evening and early morning hours. Anderson’s Red-backed Vole is known for its solitary behavior, yet they can occasionally be found in small family groups. They are adept climbers and prefer to stay close to the ground, utilizing burrows and runways to avoid predators. Their social interactions often include grooming and vocalizations, particularly in reproductive seasons.

Diet

Anderson’s Red-backed Vole primarily feeds on a herbivorous diet, consisting of seeds, berries, fruits, and vegetation. During the summer months, they enjoy a variety of fresh greens, while in the winter, they rely on cached food supplies stored in burrows. Their feeding habits play a significant role in seed dispersal and contribute to the overall health of their ecosystem.

Reproduction

The breeding season for Anderson’s Red-backed Vole typically occurs in the late spring to early summer. Females can give birth to litters ranging from 3 to 7 young after a gestation period of about 20 to 25 days. The young are born blind and helpless, relying on their mother for nourishment and protection. Notably, females may breed multiple times within a season, increasing the potential for population growth.

Conservation Status

As of current assessments, Anderson’s Red-backed Vole is categorized as a species of Least Concern by the IUCN Red List. However, habitat destruction and climate change pose potential threats that could impact their population levels in the future. Conservation efforts focus on preserving their boreal forest habitats to ensure their ongoing survival.

Interesting Facts

Despite their small size, Anderson’s Red-backed Vole can live up to 2 years in the wild. They have a unique adaptation known as ‘food caching,’ where they store surplus food for later use, which helps them survive through harsh winters. Additionally, their agility and small size allow them to escape predators effectively.

Role in Ecosystem

Anderson’s Red-backed Vole plays a crucial role in the boreal forest ecosystem as both a herbivore and prey species. Their feeding habits contribute to plant propagation, while they serve as a food source for various predators, including owls, foxes, and weasels. By maintaining the balance within their habitat, they help support biodiversity and the health of forest ecosystems.
