Abstract:

     One of the main tasks of ecology is to assess the current state of marine ecosystems and possible paths of their evolution under conditions of climate change and constantly increasing anthropogenic load. In the coastal areas of the Black Sea, the quality of the aquatic environment continues to deteriorate. Therefore, studies aimed at identifying changes occurring in the primary link of ecosystems in these water areas are extremely relevant. Their success is largely determined by the choice of methodology and methods of work. The use of an integrated approach based on identifying seasonal and interannual variability of a number of structural and functional parameters of phytoplankton, the rate of its consumption by microzooplankton, as well as  quantitative assessment of the main hydrological and hydrochemical indicators reflecting the state of the aquatic environment is proposed. Such results will help determine the phytoplankton parameters that are most sensitive to the effects of climate and anthropogenic pollution, identify the main trends in the phytoplankton community, and also predict possible ways of its further development in modern conditions.

     The presented substantiation of the methodology for monitoring of the phytoplankton community statе in coastal waters is based on the results of previous works, including field and laboratory studies. The proposed integrated approach to solving the posed problems in the Black Sea has not been applied before. The results will be of fundamental and applied value. They can be recommended for use in a set of measures to assess the sanitary state of the marine environment in recreation areas and areas of mariculture localization.

Key words: phytoplankton, the Black Sea, climate change, anthropogenic pollution.
