About this book
Seagrasses, which support a vast array of resources harvested by commercial and artisanal fisheries in the coastal regions of the world's tropics, are under threat from eutrophication, contamination with other pollutants and increased sedimentation. This collection of scientific research papers, reprinted from the "Australian Journal of Marine and Freshwater Research", reports on recent work on tropical seagrass ecosystems in coastal areas of northern Australia and the Pacific ocean.
