In early August, Eugene Odum passed away, at the age of 88, and the world lost one of the most influential figures, in the field of ecology. Dr. Odum has been dubbed “the father of modern ecology” and is credited with pioneering the concept of the ecosystem. His textbook, 'Fundamentals of Ecology' published in 1953, was the catalyst that changed ecology, from the study of the microcosm to the study of the macrocosm.
