Habitat
The Ussuri shrew inhabits moist forests, grasslands, and riverbanks in East Asia, particularly in Russia, China, and Korea. It prefers areas with dense vegetation and proximity to water sources for foraging and shelter. This species avoids open, dry areas due to its need for humidity.
Diet
The Ussuri shrew primarily eats insects such as beetles, ants, and earthworms, along with other small invertebrates like spiders and snails. It forages actively day and night, using its keen sense of smell to locate prey in leaf litter and soil. Feeding occurs frequently due to its high metabolic rate.
Behavior
The Ussuri shrew is solitary and territorial, marking its area with scent and aggressively defending it from intruders. It is primarily nocturnal, spending the day in burrows or under logs, and exhibits rapid, darting movements while foraging. This species has a high activity level and communicates through high-pitched vocalizations.
Conservation Status
The Ussuri shrew is classified as Least Concern by the IUCN, with a stable population trend in most of its range. Major threats include habitat loss from deforestation and agricultural expansion.
