Productive Characteristics of Benthic Phytocenoses in Some Areas of the Crimean Coast (Black Sea)

Abstract

The results of studying the production potential of phytocenoses of fouling of coastal hydraulic structures (groins) and solid substrates of the adjacent water area in the southwest (Lyubimovka and Foros villages), south (Cape Martyan) and southeast (eastern embankment of the city of Alushta) of Crime are reflected. Analysis of the periphyton and benthic communities showed the production superiority of Rhodophyta in periphyton and Ochrophyta in benthos. Dominants and codominants with high absolute phytomass belong to the genera Ericaria Stackhouse and Gongolaria Boehmer. The absolute phytomass of the cenosis, the relative phytomass Ochrophyta, and the Shannon index vary without exceeding the norm established for biological objects. The absolute and relative phytomass of Chlorophyta is characterized by increased variability.
