Comparison Between Atlantic and Pacific Tropical Marine Coastal Ecosystems

Coral reefs have shaped the surface of our planet far more than has any other ecosystem. They are dynamic systems, producing limestone at the rate of 400-2,000 tons per hectare per year, and influencing the chemical balance of the world's oceans. Coral reefs have been around since before the prairies or other ecosystems of flowering plants existed, yet they vanish about a million years before other groups of organisms each time there is a global mass extinction. They return after each catastrophe, however, following a long period of absence. Although coral reefs are the most productive communities in the sea, the fisheries of coral reefs are among the most vulnerable to overexploitation. Despite having the power to create the most massive structures in the world made by living creatures (including man), the thin veneer of living tissue of coral reef is particularly sensitive to natural disturbances and effects of human activities. Coral reefs are the first to go during periods of climate change, but they have always come back. This combination of attributes, creative power and fragility, resilience and sensitivity, makes management of coral-reef systems a challenge to science. Over 70% of the coral reefs in the Caribbean and Asian waters have been degraded, and perhaps a third of the 400 species of corals in Japanese waters are in danger of local extinction unless effective coastal management practices are established. This book presents what is known about factors that shift the balance between accretion and erosion, recruitment and mortality, stony corals and filamentous algae, recovery and degradation--the life and death of coral reefs. Insight into the factors controlling the direction of these processes is essential for appropriate management decisions.

The purpose of this book is to provide an organized compilation of information and techniques for all aspects of the biology and management of the Acanthaster planci species. This extraordinary coral predator has greater effects on coral reef communities than any other animal species. It can cause mortality of hard corals over large areas and have indirect effects that extend through the trophic levels of the reef community. This volume features A planci as an animal with a unique combination of morphological, physiological, and life history characteristics that contribute to its potential for major ecological impacts. It provides detailed techniques for disparate aspects of research and management (e.g., raising the animal through all life history stages, calculating growth curves, and treating victims of spinings). Chapters cover methods for surveys, tagging, and control of A. planci, in addition to an assessment of the advantages and disadvantages of each method. The extensive subject index includes more than 1,000 references to A. planci and a BASIC program for estimating coral recovery after predation by the starfish. Acanthaster planci: Major Management Problem of Coral Reefs is an essential reference for all coral reef managers and researchers.

Major Management Problem of Coral Reefs

Acanthaster Planci

This volume investigates the effects of human activities on coral reefs, which provide important life-supporting systems to surrounding natural and human communities. It examines the self-reinforcing ecological, economic and technological mechanisms that degrade coral reef ecosystems around the world. Topics include reefs and limestones in Earth history; the interactions between corals and their symbiotic algae; diseases of coral reef organisms; the complex triangle between reef fishes, seaweeds and corals; coral disturbance and recovery in a changing world. In addition, the authors take key recent advances in DNA studies into account which provides new insights into the population biology, patterns of species distributions, recent evolution and vulnerabilities to environmental stresses. These DNA analyses also provide new understandings of the limitations of coral responses and scales of management necessary to sustain coral reefs in their present states. Coral reefs have been essential sources of food, income and resources to humans for millennia. This book details the delicate balance that exists within these ecosystems at all scales, from geologic time to cellular interactions and explores how recent global and local changes influence this relationship. It will serve as an indispensable resource for all those interested in learning how human activities have affected this vital ecosystem around the world.
