"Phenotypic Plasticity is the most comprehensive book on this topic. It provides both a solid basis for understanding the subject and an inspiring synthesis of the current state of the discipline, and so can be equally recommended for students starting their research, for experts in the field and for all scientists generally interested in phenotypic plasticity. Hardly anyone will read this book without gaining new insights or new inspirations. The book is a 'must read' in the fields of evolution and ecology, and as such is an ideal topic for seminars. I highly recommend it and look forward to the next volumes in Scheiner's series."
