HYDROBIOLOGICAL CHARACTERISTICS OF A TUNDRA RIVER OF THE EAST EUROPEAN ARCTIC REGION
Species composition, quantitative development and community structure of zooplankton and zoobenthos of the Chernaya River Basin were studies in 2013. Studies covered the main channel of the Chernaya River in the lower reaches, its tributaries, lakes and small tundra water bodies. In the composition...

Species composition, quantitative development and community structure of zooplankton and zoobenthos of the Chernaya River Basin were studies in 2013. Studies covered the main channel of the Chernaya River in the lower reaches, its tributaries, lakes and small tundra water bodies. In the composition of zooplankton in the Chernaya river basin 52 species were identified. The most diverse in the water bodies were rotifers 36 species and forms. Cladocera and Copepoda were less significant, and presented by the similar number of species and forms. The basis of the fauna of copepods made Cyclopoidae, among which the most interesting is Cyclops sibiricus, arctic species characteristic of small cold-water bodies.
