title: [HYDROBIOCENOSES--A MODEL SYSTEM OF ASSOCIATIVE SYMBIOSIS].
abstract: Evolutionary formed mechanisms, that preserve and support microorganism populations in any environmental conditions up to extreme, that are the base of survival strategy, were analyzed. Natural mechanisms, that support biodiversity and stability of ecosystems of natural water bodies, are shown to determine structuredness of hydrobiont communities by associative symbiosis type.
