Seasonal and Interannual Dynamics of Active Part of Bacterioplankton in Overgrowing Littoral Zone of Rybinsk Reservoir: Influence of Gull Colonies
- 7 Downloads
This article analyzes the seasonal and interannual dynamics of active and viable bacteria in coastal waters of a large plain reservoir (Rybinsk Reservoir, Volga River) due to the activity of birds of the families Laridae and Sternidae. An increase in the number and proportion of dividing cells and cells with undisturbed nucleoids in bacterioplankton at the beginning of the nesting period of the birds (late May to early June) and their decrease by mid- July have been recorded. A decrease in the proportion of active bacteria near the gull colony has been recorded.
