The current state of zooplankton in the lake system of Bol’shezemel’skaya tundra

Abstract

The current state of zooplankton in the large lake system of Bol’shezemel’skaya tundra was determined in comparison with data from the 1960s. It was found that the annual dynamics of plankton communities took place, but their composition and structure were saved. However, some current features of tundra-lake zooplankton can be indicative of the directed development of ecosystems and the start of their eutrophication. These processes take place against the background of the attenuation of the anthropogenic impact on water bodies and certain trends in climate change. The studied lakes were oligo- and mesotrophic.
