About the Author
Professor Emeritus, Derek Burton has always been interested in how things (and animals) function. With a B.Sc. (Hons) in Zoology from the University of Wales and a Ph.D from the University of London (UK) Derek transferred his base to Newfoundland (Canada) where he has continued his investigations in fish physiology. He has taught a wide variety of courses including introductory biology, cell biology, vertebrate biology, comparative animal physiology, fish biology andgraduate courses. Major interests are fish neurobiology and colour change; the North Atlantic providing a rich source of exciting problems to study.Professor Emeritus, Margaret Burton studied zoology and comparative animal physiology at the University of London (UK) and initially focussed on invertebrates with a B.Sc. (Hons) and a Ph.D. On relocating to Canada, Margaret became involved in fish research, including work on both freshwater and marine species, concentrating on hormones. The emphasis shifted to fish reproduction which presented many fascinating areas including the ability of at least some fish species to switch off reproductionand resume it subsequently. Teaching involved a variety of introductory and more advanced courses as well as work with graduates.
