This volume is the result of research done by a group of highly distinguished scientists and students who gathered at the Hawaii Institute of Marine Biology on Coconut Island during the summer of 1983 to participate in a program titled `Coral Reef Population Biology'. It contains papers in the following sections: (1) introductory material on coral reefs and communities in Kaneohe Bay, (2) Kaneohe Bay reef populations in transition, (3) genetic structure of coral reef populations, (4) patterns of reproduction in coral reef population, (5) interactions among coral reef species, (6) physiology of the coral-​zooxanthellae relationship, (7) coral reef populations and toxic waste, and (8) mathematical models.
