Abstract
The phytoplankton development in glacier and mountain-valley lakes of Subpolar Urals were studied. 74 species of algae from 8 divisions were identified. Phytoplankton species richness was low as well as abundance and biomass indexes. The maximum abundance of 795 thousand cells/L was registered for glacier lake and the highest biomass of 3.5 mg/L were registered in the mountain-valley lake. The main groups by abundance in plankton were Bacillariophyta and Chlorophyta.
Keywords: phytoplankton, mountain-valley and glacier lakes, abundance, biomass, Subpolar Urals
