ABSTRACTs. The soil invertebrate fauna was investigated in mountain forests, sparse forests of larch and birch, and mountain tundra of the Kozhym river basin in Subpolar Ural, Komi Republic, Russia. 67 species of large-scale invertebrates and 50 species of Collembola were noted in the researched area composed of 35% (of 198 species) of macrofauna and more than 70% (of 68 species) of mesofauna at the Subpolar Ural. Among the prevailing taxonomic groups of soil invertebrates prevail are boreal forms with a high number of species with holarctic and western palaearctic distribution. The ratio of species with different types of distribution does not changed along mountain profile. Boreal species prevail in all high-altitude belts (mountain forests, larch and birch rare forests, mountain tundra). The absence of arctic species is observed among large invertebrates. The share of arctic springtails is only slightly increased in the mountain tundra belt.
