This book explains how animals use chemical communication, emphasising the evolutionary context and covering fields from ecology to neuroscience and chemistry.Building on the strengths of the first edition, this detailed introduction to pheromones has been extensively revised to cover advances made over the last ten years. It explains how pheromones work whilst emphasising the evolutionary context. The approach is integrative, covering fields from ecology to neuroscience and chemistry.Building on the strengths of the first edition, this detailed introduction to pheromones has been extensively revised to cover advances made over the last ten years.

The approach is integrative, covering fields from ecology to neuroscience and chemistry.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.Preface; Acknowledgements; List of abbreviations; List of SI prefixes; 1.
