Аннотация: Using 16S rRNA gene sequence analyses we investigated the bacterial diversity of winter bacterioplankton of two eutrophic Siberian reservoirs. These reservoirs show similarity in phytoplankton community composition in spring and autumn but tend to differ in summer in exhibiting cyanobacterial bloom. Forty-eight unique partial 16S RNA gene sequences retrieved from two libraries were mostly affiliated with the class Actinobacteria, beta subdivision of the class Proteobacteria, and the phylum Cytophaga-Flavobacterium-Bacteroides The clone library of the pond exhibiting summer cyanobacterial bloom showed more diversity in sequence composition. A significant number of bacterial 16S rRNA gene clones were closely related to freshwater bacteria previously found in different aquatic ecosystems. This finding confirms the assumption that some bacterial clades are globally distributed.

Аннотация: This article presents the history of large oil spills in freshwaters, considering the processes of physicochemical and biological degradation of oil. It discusses the toxicity of oil for hydrobionts and effects of oil pollution on communities of plankton, benthos, and ichthyofauna, as well as challenges in mitigating the environmental impact of oil spills. The discussion is concerned with the state of the ecosystem in Lake Pyasino before the incidental spill of 2020, specifically, hydrochemical indicators; species composition; and abundance and biomass of plankton, benthos, and fish. Candidate technologies for restoring the Lake Pyasino ecosystem are reviewed, including "bottom-up" biomanipulation.
