Dynamics of phytocenoses in littoral ecotone of the Black Sea bays

Structural and functional peculiarities of the summer macrophytobenthos were investigated in long-term study of littoral ecotone of the Black Sea. It was shown that most of the ground phytocenoses features undergo to inter-annual changes of various types. A character of these changes and the fact that more than a half of species constantly present in phytocenoses in different years allow to consider the state of macrophytes as dynamically balanced and providing temporal stability of the whole biosystem.
