Spatial distribution of phytoplankton in the Serezha River (Nizhny Novgorod Region)

Abstract

The investigation presents the results of studies of plankton in the area of the middle course of the riverSerezha in 2019. The floristic diversity of phytoplankton was characterized, its abundance and biomass were estimated, and the change in the morpho-functional groups of phytoplankton along the river was shown. The influence of some physical factors on the development of planktonic algae is considered. The water quality of this section of the watercourse was assessed by phytoplankton biomass, as well as using the community index and the Pantle-Bucksaprobity index.
