Plankton algal flora of the Ivankovo and the Uglitch reservoirs

摘要

On the basis of long-term investigations of phytoplankton in the Ivankovo and the Uglitch reservoirs the checklists were made, containing 480 and 415 algae species and intraspecific taxa respectively. A comparative taxonomic analysis of the algal flora was conducted and has shown a significant similarity of both laxonomic composition and indices of quantitative development of algae. The distinctions are caused by hydrologic features of the waterbodies and their trophic status.
