The study of hydrobiont communities of rivers of the Barents Sea basin included the analysis of their taxonomy composition, ecology and space distribution such of phytoplankton, zooplankton and benthos communities. The main principles of structure and functioning changes of hydrobiont communities in the river are discussed. Special attention is paid to the river continuum developing, the influence of flowing lakes and watershed urbanisations
