“Höök’s research focuses on fish and fisheries ecology in the Great Lakes. Fish communities and populations—species numbers and their traits—change a great deal from year to year, he explains. Höök studies past, current and projected future conditions to examine the factors that lead to these changes over time and across habitats. He uses a variety of research methods, including lab experiments on how fish respond to different situations, field studies and computer modeling.”
