Ecosystem ecology and Systems ecology. Odum described his role as follows: Voting, public opinion, taxes, even revolution and war could be expressed in the language of energy circuits. Odum viewed humans as playing a central role: This article is about the American ecologist.

The Ideas and Applications of H. While at Yale, Howard began his lifelong collaborations with his brother Eugene. Circuit diagrams were skillfully used to illustrate the dependence of agricultural ecosystems and industrial societies upon eoclogia fuel subsidies The intricate biological details of a particular ecosytem [ sic?

This step took him from his early interest in ornithology and brought him into the emerging field of systems ecology. By the end of the s Odum’s electronic circuit ecological simulation models were replaced by a more general set of energy symbols. This extension relied on the definition of an entity as a combination of properties that have some stability with time. This does not necessarily contradict evolutionary changes in the earth’s history since these changes may be part of a larger steady state systems.

Hutchinson who expressed the view that if a community were an organism then it must have a form of metabolism. Odum attempted to go beyond the reporting of mere ratios, a move which resulted in the first serious disagreement in systems energetics.


Society for General Systems Research Presidents. If this postulate is applied to all of nature, the resulting proposition is ecoloogia nature is as a whole in a steady state or is in the most stable form possible and constitutes one big entity. Retrieved from ” https: Some of his energy models and simulations contained general systems components.

If one is building a model of energy flow then certainly the Odum system should be given serious consideration In this model energy and matter flows through an ecosystem: From Wikipedia, the free encyclopedia. In this simulation, Odum attempted to derive an ecological analog for electrical voltage.

Howard Odum – Wikipedia

Odum was involved to a greater or lesser extent in the first calculation of the value of an ecosystem service in !

The unit of emergy past available energy use is the emjoule, as distinguished from joules used for available energy remaining now.

The term ecological engineering was first coined by Howard T. Gainesville, FloridaU. The only higher education institute to award honorary degrees to both Odum brothers was The Ohio State University, which honored H. Odum started with an overall model and in his early work used a diagramming methodology very similar to the Sankey diagrams used in chemical process engineering. Odum [was] a genius and an integrative genius seldom books petty constraints.

In writing a history of the ecosystem concept, Golley noted that Odum tended to think in the form of analogies, and gave the example, “if the world is a heat engine, then However this principle has only been demonstrated in a few experiments [38] and is not widely recognized in the scientific community.

Howard T. Odum – Wikipedia

After the war, he returned eco,ogia the University of North Carolina and completed his B. Odum pioneered a method of studying system dynamics by measuring the chemistry of the input and output water. He presented many papers on the topic at its annual conferences as well as edited the last published General Systems Yearbook.


Ecological engineering and ecosystem restoration. Howard wrote the chapter on energeticswhich introduced his energy circuit language. Exactly what this is in nature is still uncertain, as it is a new concept. In a controversial move, Odum, together with Richard Pinkerton at the time physicist at the University of Floridawas motivated by Alfred J.

In taking an energy-based view of hierarchical organization Odum also developed further the systems ecology understanding of energy quality. Odum has been described as a “technocratic optimist”.

For Howard, his energy systems language which he called “energese” was itself a collaborative tool.

Howard T. Odum

He claimed that energy was driven through ecological systems by an “ecoforce” analogous to the role of voltage in electrical circuits. It was the first center of its kind in the world that is still in operation today.

It is thus postulated that natural selection of natural systems results in the formation of entities defined as above. Kitching claimed that the language was a direct result of working with analogue computers, and reflected an electrical engineer’s approach to the problem of system representation: These small ecosystems were often constructed from fish tanks or bottles and have been called microcosms.
