Аннотация


Based on the materials of hydro-biological studies in the Volga part of the Kuibyshev reservoir in 2018 and 2019, the authors evaluated changes in the quantitative indicators and taxonomic composition of phytoplankton and zooplankton. According to the results of the study, it was revealed that in 2019 the taxonomic diversity increased, but the abundance and biomass indices of phytoplankton decreased, while zooplankton decreased only in its abundance.


Ключевые слова
