Habitat
The Tundra shrew inhabits arctic and subarctic regions of northern Eurasia, including tundra, wet meadows, and riverbanks. It prefers moist, vegetated areas with access to soil for burrowing and foraging. This species is adapted to cold climates, often found in areas with permafrost and low-growing plants.
Diet
The Tundra shrew primarily eats insects, spiders, earthworms, and other small invertebrates like snails. It has a high metabolic rate and feeds frequently, often foraging in soil and under vegetation during both day and night. This active hunting behavior helps it meet its energy needs in harsh environments.
Behavior
Tundra shrews are solitary and territorial animals, marking their areas with scent and avoiding direct contact with others except during mating. They are primarily nocturnal but can be active during the day in summer, constantly foraging due to their high metabolic rate. These shrews produce ultrasonic calls for echolocation and communication, and they create shallow burrows or use existing tunnels for shelter.
Conservation Status
The IUCN status of the Tundra shrew is Least Concern, with a stable population trend across its range. Major threats include habitat alteration due to climate change and potential predation pressure.
