【 摘 要 】

An important task for the Russian economy in the coming decades is the problem of the development of the Arctic territories. The increasing pace of human impact on the natural and urban ecosystems of this region require the study of the causes, mechanisms and consequences of such impacts. Minimizing the negative impacts on aquatic ecosystems, as being the most vulnerable, in the course of developing this region is one of the most important tasks, for the solution of which an inventory of existing biodiversity is needed. In subpolar waterbodies, algae are one of the main sources of primary production. Given the short growing season, it is the algae that are able to create a large amount of primary production almost immediately after the ice cover melts. Being producers, they will be the first to respond to any changes in the ecosystem. This study identified 35 species of algae from the divisions of Bacillariophyta, Cyanobacteria, Charophyta, and Chlorophyta. Dominated by the number of species (19) diatoms, which is typical for this region.
