Abstract

This paper describes some possible applications of stochastic methods which may be used in ecological studies. The role of stochastic methods in investigations of the dynamics of ecosystems is gaining in importance. It is a new trend which has arisen in ecological studies, related to the development of methods for the control of the environment. Stochastic methods are very useful for investigating the stability of ecosystems and the criteria of stability of natural systems, especially where the influence of permanent small-scale random disturbances have been noticed. Some criteria have been suggested and examples of use of these criteria are given in this paper. It must also be noted that the complex problems of predicting and controlling processes in natural systems must be solved by mathematical tools which permit analysis of anthropogenic factors without in-situ experimentation.
