A classic resource for teachers is now back in an updated edition. Using an inductive and experimental approach, Animal Coloration aims to increase students' awareness of the ways wild organisms are adapted to their environments.

Color can attract mates, intimidate enemies, and distract predators. But it can also conceal animals from detection. It is an adaptation to the visual features of the environment but also to the perceptual and cognitive capabilities of other organisms. Judy Diamond and Alan Bond reveal factors at work in the evolution of concealing coloration.

How the emergence of wildlife photography changed the way we think about animals.

The diversity of animal signals has been widely documented, and the generality of animal signals also tantalizingly suggests that there are common mechanisms that have selected for their origin. However, while much progress has been made on some fronts, we still lack a general theory about why the diversity of signaling structures exist. Our compilation will directly address this gap by focusing on an exciting new arena of sexual selection, namely using functional approaches to understand signaling. This approach is rooted in the idea that many signals are designed to transmit important functional imformation that is both important for issues of male quality (and hence male competition), and female choice. The increasing use of technology in sexual selection studies has enabled researchers to test whether signaling is either constrained by, or accurately transmits information about functional capacities. Further, in animals that fight vigorously, functional capacities such as endurance or strength may make the difference between winning and losing. This volume brings together a diverse collection of researchers who are actively investigating how function and signaling are related. These researchers use both a variety of methods and taxa to study animal signaling, and we believe that this integrative view is important to open up fresh vistas for why animal signals have evolved.

In the last decade, research on the previously dormant field of camouflage has advanced rapidly, with numerous studies challenging traditional concepts, investigating previously untested theories and incorporating a greater appreciation of the visual and cognitive systems of the observer. Using studies of both real animals and artificial systems, this book synthesises the current state of play in camouflage research and understanding. It introduces the different types of camouflage and how they work, including background matching, disruptive coloration and obliterative shading. It also demonstrates the methodologies used to study them and discusses how camouflage relates to other subjects, particularly with regard to what it can tell us about visual perception. The mixture of primary research and reviews shows students and researchers where the field currently stands and where exciting and important problems remain to be solved, illustrating how the study of camouflage is likely to progress in the future.

Alfred Russel Wallace (1823 - 1913) was one of the late nineteenth century's most potent intellectual forces. His link to Darwin as co-discoverer of the principle of natural selection alone would have secured him a place in history, but he went on to complete work entitling him to recognition as the 'father' of modern biogeographical studies, as a pioneer in the field of astrobiology, and as an important contributor to subjects as far-ranging as glaciology, land reform, anthropology and ethnography, and epidemiology. Beyond this, many are coming to regard Wallace as the pre-eminent field biologist, collector, and naturalist of tropical regions. Add to that the fact that he was a vocal supporter of spiritualism, socialism, and the rights of the ordinary person, and it quickly becomes apparent that Wallace was a man of extraordinary breadth of attention. Yet his work in many of these areas is still not well known, and still less recognized is his relevance to current day research almost 100 years after his death. This rich collection of writings by more than twenty historians and scientists reviews and reflects on the work that made Wallace a famous man in his own time, and a figure of extraordinary influence and continuing interest today.
