Abstract

A comprehensive survey was conducted on the soil invertebrate communities associated with the dominant plant formations in the Bolshezemelskaya Tundra (European Russia). Nematode genus richness ranged from 22 to 41 genera; peak abundances were observed in shrub tundra and post-agrogenic ecosystems and the lowest abundances were found in floodplain meadows and willow stands. Collembola assemblages included 8 to 42 species, exhibiting the highest species richness in both dwarf shrub and shrub tundra, with maximum abundance occurring in ridge-hollow complexes. Statistically significant differences in the composition and structure of nematode and collembolan communities were evident among different biotope types. Soil macrofauna comprised 24 taxa, with the greatest taxonomic richness observed in dwarf shrub tundra and post-agrogenic ecosystems, and the lowest richness in bog habitats and floodplain meadows. Across most biotopes, Diptera (constituting up to 30 % of the macrofauna) and Araneae were dominant taxa; however, in floodplain meadows Coleoptera and Lumbricidae were more prevalent. Staphylinidae and Carabidae attained high abundances in post-agrogenic ecosystems, whereas Lithobiidae were particularly abundant in shrub tundra. The data demonstrate pronounced spatial heterogeneity and ecological specificity in soil fauna within the Bolshezemelskaya Tundra, highlighting the critical role of plant community composition in shaping soil invertebrate assemblages and their structural attributes. This study advances our understanding of the biogeographical patterns and ecological dynamics governing soil invertebrate communities in Arctic ecosystems
