Odum arrived at the concept he termed hierarchical organization. Zoologymeteorologyecology and systems ecology. In a controversial move, Odum, together with Richard Pinkerton at the time physicist at the University of Floridawas motivated by Alfred J. Odum developed edologia analogue of Ohm’s Law which aimed to be a representation of energy flows through ecosystems. Nonetheless, they were oduk to estimate the total flow of energy through the entire system. Around Odum directed studies into radioecology [26] which included the effects of radiation on the tropical rainforest at El Verde, Puerto Rico Odum and Pidgeonand the coral reefs and ocean ecology at Eniwetok atoll.

This was the professional society that earlier was named the International Society for General Systems Research. Odym Howard, his energy systems language which he called “energese” was itself a collaborative tool.

Howard Odum

Inthey published the first English-language textbook on systems ecology, Fundamentals of Ecology. The intricate biological details of a particular ecosytem [ sic? Odum viewed humans as playing a central role: By dividing this conversion into ecological energy flow he calculated what he termed life support value. Odumwas an American ecologist. Circuit diagrams were skillfully used to illustrate the dependence of agricultural ecosystems and industrial societies upon fossil fuel subsidies He claimed that energy was driven through ecological systems by an “ecoforce” analogous to the role of voltage in ecolotia circuits.

In trying to solve the ecosystem, one compares it to an electrical system, for which the synthetic knowledge is much greater, and also one attempts to generalize more or less in the way of steady-state thermodynamics. Chapel Hill, North CarolinaU.


The difference between input and output, under steady state conditions, was a measure of the metabolism of the whole system. They continued to collaborate in research as well as writing for the rest of their lives. For Odum, as a large entity, the world constituted a revolving cycle with high stability. He said that the “human is the biosphere’s programmatic and pragmatic information processor for maximum performance”.

This does not necessarily contradict evolutionary changes in the earth’s history since these changes may be part of a larger steady state systems.

He was one odjm the first to discuss the use of ecosystems for life-support function in space travel. Odum together with David M. In other projects Wikimedia Commons.

Hagen, the maximum power principle, and the stability principle could be easily translated into the language of homeostasis and cybernetics systems. Electron flow in the electrical network represented the flow of material e.

The second law of thermodynamics appears to be another special case. International Society for the Systems Sciences Presidents. Such a consideration led Odum to ask two important methodological questions: The second, revised edition of his major lifework was retitled Ecological and General Systems: Views Read Edit View history.

Alexander Bogdanov Russell L. His general plan “was to characterize the chemostatic flow, to establish the qualitative and quantitative community structureto measure the production rates, and to study the mechanisms by which the community metabolism is self-regulated”.

Odum’s career, 23 September Ecological economicsecological engineeringemergymaximum power principlesystems ecology. During this time Odum became aware of the interplay of ecological-energetic and economic forces. In this way he was able to establish the stream’s energy budget”.

Odum or his views. After the war, he returned to the University of North Carolina and completed his B. Research, Past and Present, with Bruno D. It is now proposed to extend natural selection to the natural level of integration and to the large ecological entities which include both biological and inorganic components. Odum continued this work for 26 years until his retirement in Apparently the atoll was sufficiently radioactive that upon their arrival the Odums were able to produce an autoradiographic image ecologla a coral head by placing it on photographic paper.


Ecological Engineering is an emerging field of study between ecology and engineering concerned with the designing, monitoring and constructing of ecosystems.

He measured the energy input of sun and rain, and of all organic matter – even those of the bread the tourists threw to the ducks and odym – and then measured the energy that gradually left the spring. Much interesting ecological economics work grew from Odum’s life support calculations. InOdum married Virginia Wood; they had two children together. Nixon [University of Rhode Island] are among a cadre of former students who have been recognized internationally for their contributions to ecological engineering, ecological economics, ecosystem science, wetland ecology, estuarine ecology, ecological modeling, and related fields.

Odum in ; she had four children from her previous marriage. Odum, with an overview of Libfo. Odum was also honored by the journal Ecological Engineering [54] for his contributions to the field of ecological engineering and ecology in general in recognition of his 70th birthday. Odum wrote some 15 books and papers, oddum a Festschrift volume Maximum Power: This research calculated the potential value of primary production per bay surface area.

This step took him from his early interest in ornithology and brought him into the emerging field of systems ecology.
