| Abstract: | Studies on the Komarovka River, flowing in the zone of mixed conifer-broadleaf forests in the southwestern Sikhote-Alin Mountains (Primorye, Russia), have shown that the formation of river flow and multispecific phytobenthos communities takes place mainly within 60–70 km2 of its catchment area. The summer-autumn runoff rate and taxonomic composition of algae in this river segment are closely correlated with the catchment area. The relative water content of the river decreases downstream because of decrease in the number of tributaries, while changes in the taxonomic diversity of algae depend on river flow velocity and water temperature. |
