The main attention in the article, the authors focus on the shift in species composition and richness of phytoplankton with summer in autumn 2011 year. Problem is that the seasonal dynamics of phytoplankton communities in freshwater reservoirs in the vicinity of the city of Severomorsk has not previously been studied and therefore, is of great scientific interest. The aim of this work was to study the species composition of phytoplankton communities in freshwater bodies suburb of the city of Severomorsk for 2011 year.
In the result of the study, the following conclusions were drawn:
1. In summer and autumn, 2011 at stations №1 and №2 has demonstrated the prevalence of representatives of the departments: Chlorophyta, Bacillariophyta, Cyanophyta and Euglenophyta.
2. It was revealed that during the summer and autumn seasons, 2011 year there is a positive dynamics in the direction of increasing species richness of microalgae at both stations.
3. In summer and autumn seasons, 2011 year at stations №1 and №2 revealed a change of dominant species.
4. It was revealed that during the summer and autumn seasons, 2011 year there is a positive dynamics in the direction of increasing species diversity of algae at both stations.
5. The types of bioindicators to station # 1 and # 2 for different seasons, which are dominated by beta-mezosaprobics at both stations.
