Abstract
Changes in the composition and structure of cystoseira communities of the Sevastopol seashore were revealed in areas with different environmental conditions in the Vostochny Cape (the Kruglaya Bay) and in the Kosa Severnaya Cape. A high variety of macroalgae species has been recorded, as well as an increase in the number of species that form epiphytic sinusia with depth has been recorded. The community biomass is highest at 1 m depth. The average biomass at the Kosa Severnaya Cape is one of the highest for the Russian coast of the Black Sea. The contribution of the dominance species to the communities biomass varied in depth and reached a maximum in the upper sublittoral zone, decreasing with depth, this figure is higher in the Kosa Severnaya Cape than in Vostochny Cape. The share of epiphytic sinusia in the communities biomass is especially high in the second layer of the middle sublittoral zone. The lithophytic epiphyte is more pronounced in the Vostochny Cape than in the Kosa Severnaya Cape. Based on the data obtained, it was recommended to include the water area of Kosa Severnaya Cape to the marine protected area.
