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
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 .
