Зональное распределение жужелиц европейского Северо-Востока России

As a result of researches conducted in different plant communities of the natural subzones of the European North-East of Russia, the estimated species composition and diversity of Carabidae were carried out. 250 species of Carabidae from 47 genera, 24 tribes, 2 subfamilies were identified. The genera Carabus, Bembidion, Pterostichus, Agonum, Amara have high species richness in the different landscape subzones. The large amount of genera is presented by one-two species. The genera Broscus, Tachyta, Bradycellus, Acupalpus, Panagaeus, Chlaenus, Lebia, Microlestis are found only in the middle taiga, genera Philorizus and Paradromius are registered only in the northern taiga and on the Polar Ural correspondingly. The genera Calosoma, Synuchus, Anisodactylus, Oodes inhabit the taiga zone. The genera Blethisa is noted in the taiga zone and on the Ural, the genera Trechus and Dicheirotrichus are registered in the taiga and tundra ecosystems of the plain area, the genera Stereocerus is found in the plain tundra ecosystems and on the Polar Ural. Other genera are presented in different landscape zones. About 45 % species registered in the region inhabit only one natural zone. More than a half of these species is noted in the taiga. The number of such species in the tundra is not enough. Typical species are absent in the forest tundra zone. The decrease of specific number of Carabidae is observed in the direction from the southern taiga (240 species) to extremely northern taiga (13 species), from the southern tundra (89 species) to the typical tundra (28 species). Fauna of Carabidae in the forest tundra zone consists of boreal and arcto-boreal components (65 species) and represents a transition type. Ecoton effect, which manifests itself in an increase in species richness, is typical for ground beetles fauna of the forest tundra zone and southern tundra. The decrease of specific number of Carabidae is not observed in the direction from the Northern Ural (62 species) to the Polar Ural (97 species). It connects with the influence of the altitudinal zonation and inhabiting of ground beetles in the open tundra areas.
