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

Indeed, at the time they were unable to identify them. During this time Odum became aware of the interplay of ecological-energetic and economic forces. It was the presence of stability which, Odum believed, enabled him to talk about the teleology of livro systems.

Howard Odum

For the American sociologist, see Howard W. Ecosystem ecology and Systems ecology. He was supported by large contracts with the United States Atomic Energy Commissionresulting in participation by nearly scientists, who ecoologia radiation studies of a tropical rainforest [5] His featured project at University of Florida in the s was on recycling treated sewage into cypress swamps. He was one of the first to discuss the use of ecosystems for life-support function in space travel.

Odum and Howard T. In the ss Odum was also chairman of the International Biological Program ‘s Tropical Biome planning committee. From to H.

Howard Odum – Wikipedia

Nelson Michael C. Odum’s career, 23 September Odum described his role as follows: Work done at these institutions continues to evolve and propagate the Odum’s concept of emergy. Chapel Hill, North EvologiaU. The reason that systems can not proceed toward some kind of disintegration is that such a pattern has no mechanism of maintaining itself.


Thus a lot of his ideas that seemed so improbable in the past pibro considered common knowledge now. This is one of his most important contributions to the beginnings of the field of ecological engineering. Kangas noted that Odum first set out the theory that Ohm’s Law from electronics was analogous to the thermodynamic functioning of ecosystemsp.

Wiley-Interscience New York, N. Odum developed an analogue of Ohm’s Law which aimed to be a representation of energy flows through ecosystems. Much interesting ecological economics work grew from Odum’s life support calculations.

Hagen has identified the systems thinking of Odum as a form of holistic thinking. Odum in [46] well before he worked ocum the University of Florida. He said that the “human is the biosphere’s programmatic and pragmatic information processor for maximum performance”. This was one of the first projects to explore the now widespread approach of using wetlands as water quality improvement ecosystems.

Odum wrote some 15 books and papers, and a Festschrift volume Maximum Power: Odum, with an overview of H. Hence Odum also had the aim of extending the scope and generality ecologiaa natural selection, to include large entities such as the world.

He classified water bodies based on their P-R ratios, this separated autotrophic from heterotrophic ecosystems: In Odum’s work these concepts form part of what Hagen called an, “ambitious and idiosyncratic attempt to create a universal science of systems” Ibid. Odum continued this work for 26 years until his retirement in Odum greenhouse”, at the suggestion of his former student Patrick Kangas.


When combined to form systems diagrams, these symbols were considered by Odum and others to be the language of ecoligia macroscope which could portray generalized patterns of energy flow: This was described variously as the “maximum power principle” Odum”maximum power theory” Gillilandecologi power efficiency” Costanzap.

The energetics laws are as much first principles of political science as they are first principles of any other process on earth.

Howard T. Odum

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

Ecological engineering, he wrote, is “those cases where the energy supplied by man is small relative to the natural sources but sufficient to produce large effects in the resulting patterns and processes.

This page was last edited on 16 Novemberat efologia However this principle has only been demonstrated in a few experiments ligro and is not widely recognized in the scientific community. This, according to Odum, necessitated a fundamental change in the way ecologists thought about predator-prey relationships.

The second, revised edition of his major lifework was retitled Ecological and General Systems: From this view, biogeochemical cycles are driven by radiant energy. Alexander Bogdanov Russell L.
