Abstract

The first results of the study of phytoplankton and chemical composition of water of the middle and lower Vitim River are reported. The study examines spatial structure of the phytoplankton communities of river sections with various hydrologic features. New information on the species diversity of the river was obtained from the research. Main factors that limit phytoplankton density and biomass were found. It proves that physic-chemical characteristics of the water are determined by environmental factors, mainly permafrost soils. Water quality was estimated from phytoplanktic bioindicators and water chemical characteristics.
