Habitat
The Paramushir shrew inhabits moist, forested areas and grasslands on Paramushir Island in the Kuril Islands, Russia. It prefers cool, temperate environments with dense vegetation and proximity to streams or wetlands. This species is adapted to volcanic island terrain with variable weather conditions.
Diet
The Paramushir shrew primarily feeds on insects, earthworms, and other small invertebrates. It forages actively at night using its acute sense of smell, consuming food frequently due to its high metabolic rate. Feeding occurs in burrows or under leaf litter to avoid detection.
Behavior
Paramushir shrews are solitary and territorial, marking their areas with scent to deter intruders. They are primarily nocturnal, spending days hidden in burrows or under vegetation, and exhibit rapid, erratic movements while foraging. These shrews are highly active and vocal, using high-pitched calls for communication.
Conservation Status
The IUCN status of the Paramushir shrew is Data Deficient due to limited research and data. Major threats include habitat disturbance from volcanic activity and potential predation pressure.
