Primary Production of Algae in the Dnieper and Dnieper Reservoirs

RÉSUMÉ

Data of long-term studying the primary production of various ecological groups of algae (phytoplankton, microphytobenthos, and epiphyton) in the Dnieper and its reservoirs are reviewed. Phytoplankton was shown to make the greatest contribution to the production of organic matter. The process of production and decomposition displayed significant temporal and spatial variation. Recent data on the intensity of primary production showed that the Dnieper and its reservoirs are eutrophic.
