Supralittoral and shallow water seaweed communities are particularly exposed to impacts such as climate change and disturbance by humans. Therefore, their classification, the study of composition, and the monitoring of their structural changes are particularly important.

Over the past millennia, the Sea of Azov has undergone a number of very significant changes in the hydrological regime, salinity, and boundaries of biological communities. An increase in the salinity of the waters of the Azov Sea up to 15 ‰ was noted many times. This suggests that the current "record" salinity levels from a historical point of view...
