|Eugene Pleasants Odum (September 17, 1913 – August 10, 2002) was an American scientist known for his pioneering work on ecosystem ecology. He wrote and published, along with his brother, Howard T. Odum, the first ecology textbook: Fundamentals of Ecology. They continued to collaborate, in research as well as writing, for the rest of their lives.
Life depend on adequate conditions of food, water, and shelter from inclement elements and also that weather, geological, and biological factors (among others) are involved in the web of life that affords this environment. In the 1940s and 1950s, "ecology" was not yet a field of study that had been defined as a separate discipline. Even professional biologists seemed to Odum to be generally under-educated about how the Earth's ecological systems interact with one another. Odum brought forward the importance of ecology as a discipline that should be a fundamental dimension of the training of a biologist.
Odum adopted and developed further the term "ecosystem". Although sometimes said to have been coined by Raymond Lindeman in 1942, the term "ecosystem" first appeared in a 1935 publication by the British ecologist Arthur Tansley, and had in 1930 been coined by Tansley's colleague, Roy Clapham. Before Odum, the ecology of specific organisms and environments had been studied on a more limited scale within individual sub-disciplines of biology. Many scientists doubted that it could be studied on a large scale, or as a discipline in itself. Odum wrote a textbook on ecology with his brother, Howard Thomas Odum, a graduate student at Yale. The Odum brothers' book (first edition, 1953), Fundamentals of Ecology, was the only textbook in the field for about ten years. Among other things, the Odums explored how one natural system can interact with another. Their book has since been revised and expanded.
In 2007 the Institute of Ecology, which Odum founded at the University of Georgia, became the Odum School of Ecology, the first stand-alone academic unit of a research university dedicated to ecology.
