ABSTRACT

The structural characteristics of phytoplankton, including its species and taxonomic diversity, biomass, and the complex of dominant species, and seasonal dynamics of the content of oxygen dissolved in water in different sections of the Teterev river were investigated. The samples of phytoplankton were taken at the following stations: the head water of the Zhitomir reservoir, the tail water of the Zhitomir reservoir, the river section of the Teterev river located downstream of the town of Zhitomir. Relationship was established between the biomass of plankton algae and the content of oxygen dissolved in water.
