Habitat and Ecology [top]

Habitat and Ecology: Poorly known. The Tian Shan Shrew is probably an alpine specialist, as are cansulus and excelsus. The species is known to inhabit spruce forests, moist alpine meadows and stands of shrubs and reeds, generally at elevations of 2,000-3,000 m. It favors cluttered places with a thick layer of friable litter. It is active throughout the year. Most of its activity is during twilight and night, but it is occasionally encountered during the day. Its diet is diverse, but is predominately comprised of insects. Breeding begins at the end of March or early in April. At this time the testes of males enlarge to 6 mm. They remain in this condition to the end of July, and then regress to their original dimensions, 1-2 mm. Litter size: 1-8 (average 5.3). Independent young are first noticed in early July.
Systems: Terrestrial
