'Pheromones are by far the most important signals used by organisms of all kinds. Wyatt's book is an excellent text and review: up-to-date, comprehensive, balanced, detailed, clearly written, and nicely illustrated.' Edward O. Wilson 'A highly recommended source of inspiration and information for all interested in behaviour and ecology.' Bulletin of the British Ecological Society 'It would be hard to overstate the importance of this book for its contribution to the understanding of animal behaviour.' Human Nature Review '... an accessible and intelligent general work on pheromones, this book is invaluable. it is also rare and welcome in its capacity for easy and readable explanation of both the proximate and the ultimate roles of pheromones in animal behavior.' International Journal of Primatology '... an accessible textbook that offers advanced undergraduate and graduate students a data-based, integrative, and broadly comparative synthesis of this field.' Ethology '... a well-balanced account ... It will appeal to both undergraduates and researchers or anybody interested in broadening their understanding of this fascinating field of research. I am sure it will become the standard text for many years to come.' Biologist '... a most enjoyable and informative textbook ...'. Nature Neuroscience 'Wyatt's text allows students in an advanced class on pheromones to build a strong foundation of knowledge, and its readable and engaging style will launch many productive arguments along the way.' Ethology 'We are entering one of the most exciting periods in the study of chemical communication since the first pheromones were identified some 40 years ago. This rapid progress is reflected in this book, the first to cover the whole animal kingdom at this level for 25 years ... It is designed to be advanced and up-to-date, but at the same time accessible to readers whatever their scientific background. For students of ecology, evolution and behaviour, this book gives an introduction to the rapid progress in our understanding of olfaction at the molecular and neurological level. In addition, it offers chemists, molecular and neurobiologists an insight into the ecological, evolutionary and behavioural context of olfactory communication.' Ethology Ecology & Evolution '... a well-researched and interesting treatise on chemical communication.' American Entomologist
