Nonlinear theory of successions in forestry biogeocenoses: mathematical aspects

Systems analysis of biological phenomenon of succession has been carried out. The history of
the subject and the current state of art are considered. Classification of both succession process as a
whole and separate succession stages are proposed. Interaction between two main gears of succession –
competition between plant species and their interaction with abiotic part of the biogeocoenose – are
considered. Extreme nature of succession process and polygenetic structure of biogeocoenose, as a
result of succession, are demonstrated.
