​David Ainley has studied the upper trophic level dynamics of marine ecosystems for more than 40 years, and is a world-recognized expert on Adélie penguins. He has been on committees of the National Research Council to evaluate national environmental programs, was a member of the Marine Mammal Commission (Committee of Scientific Advisors) and state and international fisheries commissions, and has represented U.S. interests in various polar initiatives. Most recently, he initiated efforts that led to designation of the Ross Sea Region Marine Protected Area within international waters of the Southern Ocean. In addition, he has served as program head for meetings of the Western Field Ornithologists, Pacific Climate Conference, Pacific Seabird Group, American Ornithologists’ Union, Cooper Ornithological Society, American Geophysical Union, and Scientific Committee on Antarctic Research. He has received the Lifetime Achievement Award from the Pacific Seabird Group, and in 2022 was awarded the Ralph W. Schreiber Conservation Award by the American Ornithological Societies. He has been Editor-in-Chief of Marine Ornithology for the past 10 years. Rory Wilson is a professor in zoology within the department of biosciences at Swansea University, Wales, UK. He too, has been actively working with penguins for more than 40 years with understanding their marine ecology being his primary research thrust. His work involves developing and using new methods, particularly animal-attached tags, to study the behavioral ecology of enigmatic animals that are, otherwise, difficult to study. He has worked with ten penguin species but has also been involved in work in Africa, both Americas, Antarctica, Australia, the far- and middle East and Europe, with animals as diverse as albatrosses, armadillos, badgers, cheetahs, condors, sharks and sloths. He was bestowed a Rolex Award for Enterprise in 2006 for his animal tag developments. He was chief scientific consultant for Nat Geo’s highly acclaimed 7-part series, ‘Great Migrations’, is listed in the top 50 conservationists in the BBC power list and is a Fellow of both the Learned Society of Wales and of Academia Europaea
