| Abstract | The study of the North Caucasian coastal benthos, carried out by Institute of Oceanology RAS in 1999-2003, showed strong changes in biodiversity and species structure of coastal communities. The rise of the muddiness that coincided with the introduction of Mnemiopsis leidyi, invoked moving of phytal zone, claying of coastal sands and disappearance of the communities, which were known for the Caucasian coast from the beginning of the 20th century. Nowadays, the most depressed communities are at the south of the explored area, where the absence of dominants and subdominants of coastal communities, the decrease of coastal benthos biodiversity and quantitative abundance can be observed. At a depth of 15-25 m, where previously the core of the rich and diverse community with bivalve Chamelea gallina dominance was located, now an exotic bivalve Anadara inaequivalvis dominates. In the North, near Anapa, along with practically the same decrease of biodiversity, there is no decrease of benthos biomass in comparison with the data obtained in 1989 and during the earlier years. |
