The taiga shrew ( Sorex isodon ) is a species of mammal from the shrew family that occurs in northern Eurasia .

Mark

The taiga shrew is about the same size as the wood shrew ( Sorex araneus ). The head-trunk length is 59 to 83 mm and the tail length 43 to 52 mm. The animals weigh 7 to 15 g. The fur is dark brown on top in summer and black-brown in winter. The underside is gray-brown and contrasts only slightly with the upper side, and the tail is only indistinctly two-colored. The feet are dark brown.

Distribution and habitat

Distribution area according to IUCN

The distribution area extends from the east coast of the Baltic Sea over northern Russia (with the exception of the tundra ) to Lake Baikal and the Baekdudaegan mountainous region on the Korean peninsula . In rare cases, individuals have been found in Sweden and Norway . As the name suggests, this shrew lives in the taiga or on forest-covered mountain ranges. The habitat is always humid and often has extensive ground vegetation.

Way of life

The taiga shrew feeds on small invertebrates such as earthworms , arachnids or insects and their larvae. In rare cases she ingests carrion .

The females can reproduce three times a year. A litter has five to eight young animals, which usually only become sexually mature after a successful winter. The young can rarely mate in the same year. Life expectancy is one to one and a half years. The main cause of death is wear and tear on teeth.

Hazard and protection

In a few places the species is threatened by intensive forestry and drainage. According to the IUCN , the world population is not at risk ( “least concern” ). The species is listed in Appendix III of the Bern Convention .
