The objective of this report is to summarize information from the literature on ecological interactions between tropical coastal ecosystems and to review management issues and legislation regarding integrated, tropical marine island ecosystems and, on the basis of this review, make recommendations for future directions in research and management. The reviews of scientific research and legislation are organized into separate sections because alternating between these two frames of reference would be confusing to the reader and certain subjects would be more difficult to find if scientific and legislative materials were intermingled.
