Pymvashor Creek is the northernmost in continental Europe hydrothermal system (Bolshezemelskaya tundra, Northeast of European Russian Arctic). Our study aimed to investigate the taxonomic composition and abundance of chironomids and to evaluate the relationship of these parameters with the water temperature along the thermal gradient in the arctic Pymvashor Creek thermal system. The greatest taxonomic richness and abundance of chironomids were found in tepid waters (25 chironomid taxa), where Orthocladiinae dominated chironomid communities. Eurybiotic Chironomus Meigen, 1803 species dominated thermal springs. Cold stenotherm Pseudodiamesa (Pseudodiamesa) nivosa (Goetghebuer, 1928) and Eukiefferiella claripennis (Lundbeck, 1898) prevailed in cold karst springs. The chironomid faunas of thermal, tepid, and cold parts of the Pymvashor Creek hydrothermal water system differ statistically significantly. [ABSTRACT FROM AUTHOR] |
