Hands-On Chemical Ecology: Simple Field and Laboratory Exercises, a premiere collection of practical exercises in chemical ecology, offers tools and strategies for understanding this young science. The exercises included use general principles and follow a simple structure. Topics examined include birds, fish, insects, mammals, and plant chemistry among others. Additionally, exercises require accessible materials, ensuring that each can be easily modified and completed anywhere in the world with locally existing instruments. This text will be of value to undergraduate and graduates students and high school biology teachers. About the Author: Professor Dietland Müller-Schwarze has published Chemical Ecology of Vertebrates (Cambridge University Press 2006), co-edited 10 volumes of "Chemical Signals in Vertebrates" (Plenum Press), and written nearly 200 research papers in the field of chemical ecology. For several years, he has taught "Introduction to Chemical Ecology," an undergraduate course, and "Chemical Ecology of Vertebrates," a graduate course, at the State University of New York's College of Environmental Science and Forestry. Dr. Müller-Schwarze has also been a member of the Editorial Board of the Journal of Chemical Ecology for 27 years.
