An important problem of modern ecology is the distribution of invasive species. The main attention is focused on the colonization of soil ecosystems by foreign species of earthworms and beetles, at less – collembola. We hypothesize that the establishment of these species near hydrogen sulphid habitats results from increased frequency of introductions and warm, thermal stability in organic riched soils during the nordic winter. The study of terrestrial ecosystems near hydrogen sulfide springs was not carried out, while rare carbonate soils develop in these places (Deneva et al., 2015). Our researches were carried out on the Vodny spring - a tributary of the Vorkuta river (координаты) in the framework of the project № 18-4-4-37 “Biodiversity of invertebrates in extreme climatic conditions of the subarctic regions (Ural and adjacent areas)”. We revealed some species of Collembola, Lumbricidae and Coleoptera, among them three invasive species Folsomia fimetaria, Desoria trispinata, also Eiseniella tetraedra, which are recorded for the first time on the north-east of the european tundra.
