ABSTRACT

The dynamics of structural and functional characteristics of microbial communities over vegetation period in zone of higher aquatic plants thickets of the Rybinsk reservoir has been studied. It was established that diversity of morphological forms and bacteria abundance in this zone is higher than in open sections. Genetic diversity of bacterial communities is represented by two main phyla: Cyanobacteria and Proteobacteria. Significant fluctuations of hydrochemical regime and production-destruction processes in the reservoir occur over active vegetation and decaying of plants.
