Abstract:

The justification for the methodology of conducting research on the transformation processes of the phytoplankton community in the coastal waters of the Black Sea under conditions of global warming and increased anthropogenic pollution is provided. Such studies are aimed at solving one of the main scientific problems of ecology – assessing the current state and possible paths of evolution of marine ecosystems under the influence of climate and anthropogenic pollutants. The work should be comprehensive, implying the determination of a number of biological, hydrological and hydrochemical parameters, and be based on obtaining new data in the open coastal area, as well as comparing these results with data obtained in the bays, where anthropogenic influence is most pronounced. Research should be carried out in all seasons of the year, taking into account the spatiotemporal variability of the structural and functional indicators of phytoplankton, the rate of its consumption by microzooplankton, as well as the main parameters of the aquatic environment, reflecting its condition. To identify the reasons for the dominance of certain species in phytoplankton, it is currently necessary to carry out experiments on cultures of microalgae isolated from the plankton of the Black Sea under controlled conditions. This will help determine the ecological and physiological characteristics of common species of phytoplankton, allowing them to dominate the sea under conditions of increasing temperature stratification of the water column and anthropogenic pollution. The proposed integrated approach to research will help identify the main trends in changes in the structure and functional characteristics of the phytoplankton community at the current stage of development of the Black Sea ecosystem.

Keywords: phytoplankton, Black Sea, climate changes, anthropogenic pollution.
