Pheromones and other kinds of chemical communication underlie the behavior of all animals. Building on the strengths of the first edition, widely recognized as the leading text in the subject, this is a comprehensive overview of how pheromones work. Extensively revised and expanded to cover advances made over the last ten years, the book offers a thorough exploration of the evolutionary and behavioral contexts of chemical communication along with a detailed introduction to the molecular and neural basis of signal perception through olfaction. At a time of ever increasing specialization, Wyatt offers a unique synthesis, integrating examples across the animal kingdom. A final chapter critically considers human pheromones and the importance of olfaction to human biology. Its breadth of coverage and readability make the book an unrivaled resource for students and researchers in a range of fields from chemistry, genetics, genomics, molecular biology and neuroscience to ecology, evolution and behavior. 'Tristram Wyatt's Pheromones and Animal Behavior takes us on an interdisciplinary voyage along one of the most ancient communication channels. He explores, in depth, how chemical signals and signature mixtures shape social interactions, and why. I enjoyed his writing style, which also makes the book accessible to non-specialists. This excellent second edition is heavily revised and enriched. It unravels some of the mysteries of the world of pheromones, explaining what they are, their origins, functions, evolution, and the communication purposes they serve in a large variety of animals. Wyatt takes us through a well-judged range of examples of some of the amazing chemical communication strategies, from ants right up to the scent of human attraction. The book is far-reaching, inspiring, and brilliantly illustrated.' Patrizia d'Ettorre, University of Paris 13, Sorbonne Paris Cite 'This thoroughly modern revision of the classic first edition is an amazing journey through the landscape of pheromones. Tristram Wyatt engagingly covers a vast territory, deftly condensing thousands of important academic papers into a lively, informative, and richly illustrated book. Everything from insects to the possibility of sexy secretions from humans is covered from the points of view of neuroethology, chemistry, molecular biology, and more. The book is a must-read for any undergraduate or graduate student or working scientist interested in a singular comprehensive resource on this fascinating topic.' Leslie B. Vosshall, Rockefeller University, New York 'By highlighting the power of pheromones, this book illustrates how chemical signals rule the animal kingdom. Wyatt challengingly dissects the phenomena derived from chemical communication at molecule, receptor, and neural levels, based on an enormous range of information from past and recent literatures ... I like his point that the importance of chemistry in understanding pheromone action should be re-emphasized, given the recent trends in science that rely too much on molecular biology and neuroscience techniques. This book can be used as a textbook for students but also for researchers, as ... Wyatt gives many valuable insights that direct readers into the research. I cannot help thinking that I will cite this book in all research papers that I will publish in the future.
