The Application of Ecological Modelling to Toxic Contaminants and Ecosystem Stress
Abstract This review analyzes the application of ecological modelling to problems concerning toxic contaminants and ecosystem stress and explains the purpose and methods of the systems ecology approach, which could be useful to individuals involved in data gathering activities. The review provides operational definitions of ecosystem stress, gives a description of methods of the systems approach and analyzes several topics of interest such as the application of expert system methods in the environmental field and methods of ranking. Recommendations are given to managers in charge of monitoring activities can benefit by interacting with systems ecologists. Four topics are analyzed in detail: 1) Ecosystem stress. To assess the impact that toxic contaminants have on ecosystems we must give an operational definition of ecosystem stress and how to observe it. 2) The purpose and methods of the systems ecology approach. 3) The application of artificial intelligent methods in the environmental field. 4) Methods of ranking.
