摘要

A total of 171 algae species was found in plankton of slightly mineralized oligotrophic water bodies of the Molodo river basin located in the region of diamonds mining. From the floristic and ecogeographic aspects, phytoplankton of these water bodies possesses typical characteristics of algae communities of the northern undisturbed water bodies. On the whole, phytoplankton of the Molodo river basin is characterized by rather low quantitative indices of its development, which is conditioned by a short vegetation period and by low water salinity. The material obtained at the initial stage of industrial development of the territory can be used as the basis for biomonitoring.
