ABSTRAKT

Dynamics of the species composition of macrophytes and the structure of benthic phytocenoses were studied in the tidal zone of the Black Sea (Omega Bay). Samples were taken in summer 1987 and 1997. In summer 1997, macrophytes were represented by a larger number of species. In 1997 they consisted mainly of representatives of Rhodophyta, the contribution of Chlorophyta remained unchanged, whereas the number of species of Phaeophyta decreased by a factor of two. Within the studied area of water, the number of poly- and oligosaprobic species increased, whereas the number of mesosaprobic species decreased by a factor of two. The biomass of macrophytes decreased by a factor of four. The changes found were conditioned by eutrophication of the coastal zone of some sections of the Black Sea in 1987-1997.
