Abstract—The paper describes a method of graphical analysis developed for freshwater ecosystems. The method was first used to analyze the structure of phytoplankton communities in the Ivankovo and Rybinsk reservoirs. Step-by-step spatial transformations of phytoplankton structure were revealed. Three scenarios of their transformation were highlighted.

Keywords: graphical analysis, phytoplankton, taxonomic structure
