Abstract
Proceeding from analysis of data obtained in experiments with model ecosystems regression equations are presented. They describe the influence of some zinc and chromium concentrations on the primary production of phytoplankton from the Rybinsk reservoir. All the experiments were conducted by the scheme of full factorial experiment (FFE 32).The data obtained testify to succession variations in the phytoplankton community intended to the formation of a new structure with a high portion of algae resistant to the studied metals.
