Regional features of variability in structural organization of the Lower Don phytoplankton

The variability of quantitative and qualitative parameters of phytoplankton communities in different parts of Lower Don was considered. It is shown that the characteristic feature of the development of phytoplankton for long period (1981–2011) was high variability of quantitative indicators, suggesting an unstable state of the community. In the phytoplankton species composition, from 7 to 82 species was recorded; the dominant ones were diatoms and green algae. Anthropogenic pressure on ecosystems in the lower reaches of the River Don can cause both eutrophic and toxic response from the community, accompanied by structural changes.
