The book presents an integration of existing ecosystem theories in such a comprehensive way as to enable a full ecological and theoretical pattern to be presented. It shows that ecosystems and their reactions may be understood, provided that all basic systems ecology is applied to different aspects of the properties of ecosystems. Since the publication of the previous two editions of this book, ongoing research and discussions on an international scale have greatly clarified and enhanced this pattern. This progress is presented as Chapter 16 in this new, third edition. It is shown that the integrated ecosystem theory presented can be applied to explain various ecological observations and rules. Audience: Researchers and decision makers whose work involves the study of ecosystems and ecology. This book is also recommended for use in graduate courses.
