To a study of mites of the genus Arctoseius (Parasitiformes, Ascidae) from the far north: 3. ranges and ecological preferences of species

摘要

Among 16 species of the genus Arctoseius found in Palaearctic polar deserts and arctic tundra, four species were described as new to science (Communications I and 2) and three species were reported from Russia for the first time. The circumpolar distribution was proved for eight species. The following species complexes were revealed: (1) hyperarctic species, occurring exclusively (A. tschernovi sp. n.) or predominantly (A. miranalis sp. n. and A. babenkoi sp. n.) in High Arctic regions; (2) euarctic species, equally inhabiting both tundra and polar desert zones (A. ornatus, A. productus sp. n., A. tajmyricus, A. minor, A. confusus, and A. idiodactylus), and (3) hemiarctic species, inhabiting all tundra subzones and only occasionally found in polardeserts (A. weberi, and species of the multidentatus group). The polyzonal species A. semiscissus was found in polar deserts only in bird nests. Along with the soil-dwelling species in the principal zonal biotopes (A. ornatus, A. weberi, A. robustus, A.productus sp. n., etc.), the species associated with intrazonal meadow vegetation (A. confusus, A. idiodactylus, species of the multidentatus group) and those inhabiting various eutrophic substrates (A. tschernovi sp. n., A. babenkoi sp. n., and A. minor) were distinguished.
