This book shows the complexity of plant signaling and behavior in an ecological context and is intended to increase our understanding of it. It reflects the multifaceted interactions between plants and other organisms that affect their growth and development. In addition it puts emphasis on the effects of plant signaling and behavior on other trophic levels. This field of research is growing and developing rapidly, and new findings are regularly reported. Thus, this book provides a broader view of the field and represents a valuable reference work on the current state of research.
