Honorary Lifetime Memberships in CSEE recognize eminent Canadian ecologists or evolutionary biologists who have demonstrated a lifetime of research and contributions to ecology or evolution.

Chris (Evelyn Chrystalla) Pielou is recognized for her excellence and distinguished service in the fields of mathematical ecology and ecological diversity. She wrote six books in the area of Mathematical Ecology and Ecological Diversity between 1969 and 1984. After her retirement, she continued to write popular books on ecosystems and environmental topics. In journal articles she developed a mathematical measure of associations among groups of species, which serves as a measure of the “structure” of multi-species communities. She was also interested in inter-relationships among ecology, biogeography, and the paleo-equivalents of ecological communities.

C.S. (Buzz) Holling is best known for two scientific advances: the functional responses of predators to prey and the concept of the resilience of social-ecological systems. These ideas have become cornerstones to contemporary ecosystem management and research into sustainability and conservation. Dr. Holling has made, and continues to make, important contributions to ecology and evolution. He has profoundly influenced students, researchers through his research and teaching.

Harold H. Harvey was instrumental in identifying the acidification of North American aquatic ecosystems, and the impact this change had on the ecosystems. He devoted a great amount of his time to raise the consciousness of the Canadian and American public and policy makers to acidification problems. His numerous critical contributions eventually led to both countries imposing strict controls on emissions. His research and its impact on the public and policy makers ultimately minimized further degradation of hundreds of thousands of lakes and streams in North America thereby allowing their chemical and ecological recovery.
