Yunnan Red-backed Vole

Common Name: Yunnan Red-backed Vole
Scientific Name: Myodes backei

Habitat

The Yunnan Red-backed Vole primarily inhabits the mountainous regions of southwestern China, particularly in Yunnan province. These small mammals are typically found in high-altitude grasslands, forests, and alpine meadows, where they thrive in cool and moist environments.

Physical Characteristics

The Yunnan Red-backed Vole is a small rodent, measuring approximately 8 to 10 centimeters in body length, with a tail that is about 4 to 7 centimeters long. They have a distinct reddish-brown or rust-colored stripe along their back, contrasting with their paler underbelly. This coloration serves as effective camouflage within their natural habitat. Their small, rounded ears and short legs are characteristic features of the species.

Behavior

Yunnan Red-backed Voles are primarily nocturnal, becoming active during the night to forage for food. They are known for their burrowing behavior, creating extensive tunnel systems to escape predators and store food. These voles are also highly social, often found in small groups, which aids in mutual protection and foraging efficiency.

Diet

This species primarily feeds on grasses, roots, seeds, and various herbaceous plants found in its mountainous habitat. The Yunnan Red-backed Vole has adapted a diet that thrives on the abundant vegetative matter available in its environment, playing an essential role in seed dispersal.

Reproduction

Reproductive activity in Yunnan Red-backed Voles typically occurs in the spring and summer months. After a gestation period of approximately 20 to 30 days, females give birth to 3 to 6 young. Offspring are born blind and rely on their mother’s care for survival in the early stages of life. Breeding pairs often remain together to nurture their young until they are independent.

Conservation Status

The Yunnan Red-backed Vole is currently classified as “Vulnerable” by the International Union for Conservation of Nature (IUCN) due to habitat loss resulting from agricultural expansion and climate change. Conservation efforts are necessary to protect their natural habitats and ensure their survival.

Interesting Facts

One fascinating fact about the Yunnan Red-backed Vole is its unique ability to lower its body temperature, allowing it to survive in extremely cold conditions. Additionally, these voles communicate using high-pitched vocalizations that help maintain social bonds within their groups.

Role in Ecosystem

The Yunnan Red-backed Vole plays a crucial role in its ecosystem by aiding in seed dispersal and serving as prey for larger predators. Their burrowing habits also promote soil aeration and nutrient cycling, contributing to the health of their high-altitude habitats.
