Ecological Niches: Linking Classical and Contemporary Approaches by Jonathan M. Chase and Mathew A. Leibold is a book that aims to bridge classical and contemporary approaches in community ecology. The authors argue that the niche concept, traditionally defined as a species' environmental needs or its impacts on the environment, is antithetical, and that a dialectical or synthetic approach is more effective. They propose the Zero Net Growth Isocline (ZNGI) as a measure of the niche, which incorporates both a species' needs and its impacts. The book reviews the history of the niche concept and presents a framework for predicting species competition based on Tilman's R* principle. The authors extend this concept to explain various ecological phenomena, such as species sorting, succession, and the intermediate disturbance hypothesis. However, the book is criticized for covering too many phenomena with too little analysis and for lacking empirical testing of the ZNGI approach. The authors acknowledge that their models may not be directly testable but argue that they serve as a springboard for important insights. The book is concise and well-organized, but some readers may find it lacking in rigor and testability. The authors admit that their approach does not yet represent a rigorous scientific theory, but they hope it will help revitalize community ecology. The book is a valuable contribution to the field, but further development and empirical testing are needed to establish it as a paradigm in ecology.Ecological Niches: Linking Classical and Contemporary Approaches by Jonathan M.
