Coral reefs declined worldwide during the 1980s and 1990s, making them perhaps the most endangered marine ecosystem on Earth. This realization spurred John W. Tunnell Jr. and others to write a comprehensive book that would raise awareness of coral reefs and their plight. Tunnell and coeditors Ernesto A. Chavez and Kim Withers present an integrated and broad-ranging synthesis, while Mexican and U.S. experts assess the current state of these fragile systems and offer a framework for their restoration. Beginning with a history of the research done in this region, Coral Reefs of the Southern Gulf of Mexico covers the geography, geology, oceanography, ecology, and biodiversity of the thirty-eight emergent or platform-type coral reefs in the southern Gulf. The editors include chapters on the biota-from algae to fish-followed by a look at environmental impacts, both natural (such as hurricanes and red tides) and human (such as ship groundings and dredging). The book closes with a discussion of conservation issues, which is both descriptive and prescriptive in its assessment of what has been done and what should be done to protect and manage these vital ecosystems.
