John Magnuson’s research activities focus on long-term ecological research on lake ecological systems, potential influence of climate change on inland waters, fish and fisheries ecology, biogeography and landscape ecology of lake and stream systems, and ecological dynamics of biodiversity and invasion.

Dr. Magnuson is a prolific researcher, having published over three-hundred research papers and six books since 1962.

In addition to teaching and research responsibilities, he has been involved with a number of commissions and scientific organizations propagating a wide range of disciplines, from global climate change to species conservation to the future of aquatic habitats.
