Daniel Hunt Janzen

U.S.A. / January 18, 1939
Tropical Biologist; Professor, University of Pennsylvania

“Pioneering Study of Biodiversity in Tropics and Its Maintenance Mechanisms”
As a pioneer of tropical biology, Dr. Janzen has formulated a large number of unique hypotheses, including mutualism for defense against predators and predation as a basis for biodiversity, making significant contributions to the flourishing of tropical ecology. Applying his special knowledge to practical situations, he has also been active in biological and environmental conservation in the tropics.
