Principles of Classification and Some Mechanisms of Structural and Functional Transformations of Freshwater Ecosystems under Conditions of Anthropic Load

Краткое описание

Anthropic factors influencing aquatic ecosystems were classified into the following six types: acidification, eutrophication, toxification, and radioactive, organic and thermal pollution. Appropriate states of anthropically changed (altered by human impact) ecosystems and symbols to designate them were proposed. Biological indicators corresponding to each state were determined. A concept of chain reactions in aquatic ecosystems as a response to anthropic influence is established and justified. Structural transformations of communities in aquatic ecosystems and methods of their analysis and prediction by means of cenograms, as well as their computer models, are considered. Six main states of aquatic ecosystems registered under conditions of anthropic load were determined. They include balanced (homeostatic), unbalanced, transformed, and degraded states, as well as the state of "ecological death" and reanimated (restored) state.
