The architectonics of cystoseira phytocenoses canopies in the Black Sea

The article reviews the architectonics of the vegetative canopy as represented in the upper synfolium of cystoseira associations. This canopy is distinguished by a unimodal type of the biomass vertical distribution where 75%-85% of the total dry mass is concentrated at a maximum in its lower parts. The manner in which the cystoseira thallome biomass of various age groups is distributed in the canopy from top to bottom is described by a series of unimodal curves. The epiphyte synusia species are predominantly found in the upper parts of the canopy.
