Abstract:

   Succession changes in accumulative cultures of phytoplankton, which occurred within 4 months, were revealed. The material for the isolation of cultures was samples of sea water from three bays with various anthropogenic loads located on the Sevastopol coast (the Black Sea, the Crimea peninsula). After a month of cultivation of algae on the nutrient medium, 28 taxa were found, and at the end of the experiment the number of taxa decreased to 13. It was found that in the same conditions of the laboratory experiment within a month a similar systematic structure of microalgae taxocenes was formed, аnd it did not depend on the exposure time, place and time of material selection.

Keywords: microalgae taxocenoses, cyanobacteria, accumulative cultures, coastal water area of Sevastopol, the Black Sea, Crimea peninsula.
