Zooedaphon of the East-European tundra

The zooedaphon diversity of zonal plant communities of the south-eastern part of Bolshezemelskaya tundra as the least explored territory in the East-European tundra, is characterized. In large-bushy, small-bushy and shrub mosslichen tundra 32 genera of nematodes, 60 species of springtails, 3 - earthworms, 1 - centipedes, 33 - ground beetles, 36 - rove beetles and 1-2 species of beetles from five families are registered. Small spiders (Aranei) and insects from orders Thysanoptera, Homoptera, Hymenoptera and Diptera are characterized by high density in the zooedaphon of the researched tundra. The density of meso- and macrofauna of the researched tundra is different. Opposite trends of density change are observed for soil mesofauna. The number of nematodes is reduced, and that of microarthropods, in contrast, is increased in the gradient "large- bushy - small-bushy - shrub moss-lichen tundra". The density of macrofauna is almost three times higher in small-shrub and shrub moss-lichen tundra than in large-bushy tundra. The original data on the diversity and abundance of soil zoocenoses of the researched area are included in the information system "Soil fauna of the Komi Republic".
