The Proceedings of the 18th International Seaweed Symposium provides an invaluable reference to a wide range of fields in applied phycology. Papers cover topics as diverse as systematics, ecology, commercial applications, carbohydrate chemistry and applications, harvesting biology, cultivation and more. Contributions from all parts of the world give the volume exceptional relevance in an increasingly global scientific and commercial climate. Like its predecessors, this volume provides a benchmark of progress in all fields of applied seaweed science and management, and will be referred to for many years to come. The volume will interest researchers, students, resource managers and natural product chemists. Reprinted from Journal of Applied Phycology, volume 18, issues 3-5, (2006)
