Краткое описание

A possibility of applying a morpho-functional approach in estimating structural and functional organization of benthic algal communities with the aim of performing express diagnostics of tropho-saprobic condition of coastal ecosystems is discussed. In determining the tropho-saprobic category of ecosystems, indices of surface of phytocenoses, as well as of specific surface of populations have been used as quantitative criteria determining morpho-functional structure of the benthic vegetation. Classification of trophic levels of aquatic environment has been suggested. It is based on the following surface indices of benthic algae communities: xenotrophic < 5; oligotrophic 5−19, mesotrophic 20−40; eutrophic 41−70; polytrophic 71−120; hypertrophic >120 (units). Empirical values of the surface indices of phytobenthos for ecosystems with different trophic levels have been presented. Based on the morpho-functional structure of phytobenthos, the modern state of the coastal part of the Ukrainian shelf of the Black Sea may be characterized as mesotrophic-eutrophic.
