ABSTRACT. Numerous water bodies in the northern portion of Eastern Siberia are poorly studied both in their species composition and community structure. The aim of this study is to provide an inventory of the freshwater microcrustaceans of Bykovsky Peninsula and neighboring territory (North Yakutia, Russia) and to analyse the community structure in the studied water bodies with the aim of revealing separate environmental factors affecting it. In toto, we identified 19 copepod species (belonging to 14 genera) and 16 branchiopod species (12 genera). Seven species were first records from this area of NE Siberia, namely calanoid copepods Acanthodiaptomus denticornis, Arctodiaptomus wierzejskii cyclopoid copepods Acanthocyclops venustus, Diacyclops crassicaudis, D. languidoides; cladocerans Eurycercus cf. glacialis, Pleuroxus cf. trigonellus. The fauna of Bykovsky Peninsula and neighbouring territory is very poor and mainly represented by eurybiotic taxa with wide Palearctic or Holarctic ranges. Differences in community structure of different water bodies could be explained mainly by abiotic preferences (i.e. in conductivity/salinity and temperature) of dominant species.
KEY WORDS: Crustacea, Cladocera, Copepoda, fauna, biodiversity.
