New Data on Biota of Some Lakes in the Western Part of the Putorana Plateau
subject: zooplankton, Zoobenthos, lake, LAMA, Sobach’e, Kutaramakan
description: Species composition and abundance of zooplankton and zoobenthos of large Norilsk Lakes (Lama, Sobach’e) and Kutaramakan Lake in the western part of the Putorana plateau were studied in August-September of 2013–2014 after a long gap. Senecella calanoides Juday (Copepoda: Calanoida) in zooplankton and 5 species of water mites (Acalyptonotus violaceus Walter, Hygrobates (Hygrobates) foreli (Lebert), Lebertia (Mixolebertia) densa Koenike, Lebertia (Pilolebertia) porosa Thor, Oxus (Gnaphiscus) setosus (Koenike) (Hydrachnidia)) in zoobenthos were recorded for the first time in the investigated lakes. A total of 64 taxa of benthic invertebrates were found, of which 42 taxa were Chironomidae. Zooplankton species composition of Lama and Cobach’e lakes was similar and differed from that of Kutaramakan lake by presence of Senecella calanoides and Limnocalanus macrurus Sars (Copepoda: Calanoida). In zoobenthos of Kutaramakan lake amphipods were not found. Lama and Kutaramakan lakes can be classified as ultraoligotrophic water bodies based on biomass of zooplankton and zoobenthos. Among the studied lakes, Cobach’e lake has the greatest biomass, and based on the biomass of zooplankton in some zones of > 0.5 g/m3, it is an oligotrophic water body, and based on an average biomass of zoobenthos 3.85 g/m2 an α-mesotrophic one
