STABILITY OF TERRESTRIAL ECOSYSTEMS TO PLANT PESTS: AN AXIOMATIC APPROACH.
Gleb I.Vasechko, Cand.Sc. (Biology)
Annatation
It has been developed a generalization of literature data, personal communications of scholars, and own findings that has resulted in a theory describing the phenomenon of stability of terrestrial ecosystems to plant pests - herbivores and phytopathogens. The stability is proceeded by a number of factors suppressing all the diversity plant pest species inhabiting of a given ecosystem. It has been shown stressors, which decrease ecosystem stability. The generalization is based on the Ch.Darwin's regularities of the evolution and the Ch.Darwin's ideas on population dynamics of organisms. It has been proposed practical implications to increase the stability against separate species of plant pests, and recommendations on maintenance of general stability of ecosystems against abiotic and biotic stressors. The text is presented as a list of generalizations - axioms and massif of data for substantiation of these axioms. The used approach has allowed developing a new system of knowledge- Natelogy, which is the first branch of science established in XXI century.

Figure 8 demonstrates the effect of clear-cutting on the trees, which were left in stands bordering with a cut-over area. On the border exposed to the south, stocking density is much less than that in depth of this forest. This is a result of mortality of trees due to sun scold in standing position and windthrow at not too might wind. The weakened trees were colonized by stem borers. The photograph was made approximately five years after the cutting. The died trees were withdrawn at sanitary cuttings. Because the mortality of trees grows with the number of years of the exposition, it should conduct clear-cutting in adjacent forest as soon as possible. On the opposite border exposed on the north, the state of trees is much better.
