Краткое описание

The ecological and taxonomic structure of the dominant complex and peculiarities of the quantitative development of benthic phytocenoses of the coastal ecotone of the Crimea are studied in a spatial-time aspect. Sizes and limits of biomass variation in phytocenoses and their interrelation with ecotope conditions are established. The contribution of species and different divisions of algae to the total biomass of coastal phytocenoses is determined. It is shown that average biomass of Rhodophyta is substantially lower than that of Chlorophyta and Phaeophyta. It is revealed that brown algae dominate to the greatest extent. Spatial localization of poly- and monodominant communities is established. Seasonal dynamics of the ecological and taxonomic composition and of the quantitative development of dominants and codominants are investigated. Irrespective of the season marine, perennial, oligosaprobiontic algae dominate in open regions, while in closed regions, subjected to pollution and desalination, saltish-water-marine, annual, polysaproobiontic algae are dominants. It has been shown by the Jaccard coefficient of community that a degree of similarity in dominants between seasons is insignificant. Under dynamic conditions of coastal shallow waters biomass of phytocenoses, on the whole, and Chlorophyta, Phaeophyta and Rhodophyta, in particular, are subjected to variability in different years. Only a share of biomass (%) in dominants and codominants is relatively stable.
