| Абстракт | The phytoplankton biomass interannual variability, its taxonomic and species composition in the surface layer of the Sevastopol Bay waters during the period of 2000-2014 were analysed. Gradual decrease in the total algae biomass and relative contribution of the diatoms, as well as an increase in the dinoflagellates and coccolitophores contribution, was detected. During the research period relative diatoms biomass decreased on average from 83 % to 44 %, and relative dinoflagellates biomass increased on average from 14% to 38 %. The remaining phytoplankton biomass was generated mainly by coccolitophores, where Emiliania huxleyi (Lohmann) W.W.Hay & H.P.Mohler was dominating. According to our calculations, their relative contribution was increasing on average from 2 % to 11 %. The restructuring of the phytoplankton taxonomic composition was occurring mainly as a result of water temperature increase and, to a lesser extent, due to decreasing in the nutrients concentration. For the entire 15-year observation period the positive trend of average annual temperatures values variations was detected with a sufficiently high correlation coefficient (R2 = 0.66). The water temperature increase, especially in a summer, adversely impacts functioning of the most diatoms species. This, probably, is the main reason for the restructuring of their species composition, what is largely pronounced in the summer. In the Sevastopol Bay in the summer 2010- 2014, representatives of the Chaetoceros genus were not observed among the dominated species, although they caused algae blooms in the previous years. However, other species were detected: Nitzschia tenuirostris Mer., Striatella interrupta (Ehrenberg) Heiberg, Cyclotella caspia Grunow и Pseudosolenia calcar-avis (Schultze) B.G.Sundström. The composition of the dinoflagellates dominant species was not varied over the entire observation period. Among them, the representatives of Prorocentrum, Gymnodinium and Ceratium genus were dominating. Variation of the phytoplankton taxonomic and species composition caused a decrease on average annual phytoplankton growth rate, microzooplankton grazing and, also, net primary production. It indicates that the matter and energy flow from phytoplankton to microzooplankton, as well as to the upper trophic levels, is decreasing.
