This book documents and examines the state of health of coral reefs in the eastern tropical Pacific region. It touches on the occurrence of coral reefs in the waters of surrounding countries, and it explores their biogeography, biodiversity and condition relative to the El Niño southern oscillation and human impacts. Additionally contained within is a field that presents information on many of the species presented in the preceding chapters.

Coral reefs are the largest landforms built by plants and animals. Their study therefore incorporates a wide range of disciplines. This encyclopedia approaches coral reefs from an earth science perspective, concentrating especially on modern reefs. Currently coral reefs are under high stress, most prominently from climate change with changes to water temperature, sea level and ocean acidification particularly damaging. Modern reefs have evolved through the massive environmental changes of the Quaternary with long periods of exposure during glacially lowered sea level periods and short periods of interglacial growth. The entries in this encyclopedia condense the large amount of work carried out since Charles Darwin first attempted to understand reef evolution. Leading authorities from many countries have contributed to the entries covering areas of geology, geography and ecology, providing comprehensive access to the most up-to-date research on the structure, form and processes operating on Quaternary coral reefs.

This volume provides an accessible scientific introduction to the historical geography of Tropical Pacific Islands, assessing the environmental and cultural changes they have undergone and how they are affected currently by these shifts and alterations. The book emphasizes the roles of plants, animals, people, and the environment in shaping the tropical Pacific through a cross-disciplinary approach involving history, geography, biology, environmental science, and anthropology. With these diverse scientific perspectives, the eight chapters of the book provide a comprehensive overview of Tropical Pacific Islands from their initial colonization by native peoples to their occupation by colonial powers, and the contemporary changes that have affected the natural history and social fabric of these islands. The Tropical Pacific Islands are introduced by a description of their geological formation, development, and geography. From there, the book details the origins of the island's original peoples and the dawn of the political economy of these islands, including the domestication and trade of plants, animals, and other natural resources. Next, readers will learn about the impact of missionaries on Pacific Islands, and the affects of Wold War II and nuclear testing on natural resources and the health of its people. The final chapter discusses the islands in the context of natural resource extraction, population increases, and global climate change. Working together these factors are shown to affect rainfall and limited water resources, as well as the ability to sustain traditional crops, and the capacity of the islands to accomodate its residents.
