Coral reefs represent the most spectacular and diverse marine ecosystem on the planet as well as a critical source of protein and income for many millions of people. Ecologically they are as complex as they are diverse and colourful. However, the combined effects of human activities have led to a rapid decline worldwide in the health of reefs. This timely book provides an integrated overview of the function, physiology, ecology and behaviour of coral reef organisms. Each chapter is enriched with a selection of ‘boxes’ on specific aspects written by internationally recognized experts. As with other books in the Biology of Habitats Series, the emphasis in this book is on the organisms that dominate this marine environment, although pollution, conservation, climate change and experimental aspects are also included. Indeed, particular emphasis is placed on conservation and management due to the habitat’s critically endangered status. A global range of examples is employed which gives the book international relevance. This accessible text is intended for students, naturalists and professionals and assumes no previous knowledge of coral reef biology. It is particularly suitable for both senior undergraduate and graduate students (in departments of biology, geography, and environmental science) taking courses in coral reef ecology, marine biology, oceanography and conservation biology, as well as the many professional ecologists and conservation biologists requiring a concise overview of the topic. It will also be of relevance and use to reef managers, recreational divers and amateur naturalists.
