The current state of the Zostera marina + Stephanocystis crassipes community in the Eastern Bosphorus Strait, Sea of Japan A.V. Zhirmunsky Institute of Marine Biology, National Scientific Center of Marine Biology, Far Eastern Branch, Russian Academy of Sciences, Vladivostok 690041 E-mail: The state of the community of macrophytes Zostera marina + Stephanocystis crassipes in a bay off Cape Tokarevsky (Eastern Bosphorus Strait, Sea of Japan) was evaluated using the method of sample plots in June 2014. The taxonomical and morpho-functional composition, as well as the structure of the community have been studied. A total of 39 species of marine macrophytes have been found in this area, including 6 species of Chlorophyta, 22 species of Rhodophyta, 10 species of Phaeophyceae, and one species of Tracheophyta (Zostera marina), which constitute 15%, 56%, 26%, and 3% of the total number of species in the community, respectively. The studied phytocenosis is characterized by a poor taxonomic composition, high biomass of opportunistic species (auxiliary species on the dominance scale), and the proportions of higher algal taxa typical of the clean waters of Peter the Great Bay. Thus, the Zostera marina + Stephanocystis crassipes phytocenosis, evaluated based on a combination of these characteristics, can be regarded as being in an early stage of anthropogenic transformation, and the waters classified as moderately polluted. Key words: seagrasses, macroalgae, community structure, anthropogenic pollution, subtidal zone, Eastern Bosphorus Strait, Sea of Japan. |
