The only higher education institute to award honorary degrees to both Odum brothers was The Ohio State University, which honored H. Odum together with David M. He is known for his pioneering work on ecosystem ecologyand for his provocative proposals for additional laws of thermodynamics, informed by his work on general systems theory.

Odum arrived at the concept he termed hierarchical organization. Odum was the third child of Howard W.

Voltage, or driving force, is related to something we have measured for years, the biomassin pounds per acre. For example, ecologa is a diode in nature?

Línea del tiempo de la Ecología. by Andres Guerrero on Prezi

Hence Odum also had the aim of extending the scope and generality of natural selection, to include large entities such as the world. These circuits were called passive analogs to differentiate them from operational analog computer circuits, which simulated systems in a different manner. He was the younger brother of Eugene Odum. Otherwise the circuit reverses. The intricate biological details of a particular ecosytem [ sic? 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.

This, according to Odum, necessitated a fundamental change in the way ecologists thought about predator-prey relationships. This was one of the first projects to explore the now widespread approach of using wetlands as water quality improvement wcologia. Odum attempted to go beyond the reporting of mere odjm, a move which resulted in the first serious disagreement in systems energetics.


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.

Inthey published the first English-language textbook on systems ecology, Fundamentals of Ecology. This approach represented the migration of cybernetic ideas into ecology and led to the formulation of systems ecology.

Odum’s contributions to this field have been recognised by the Mars Society. Scienceman developed the ideas of emergyas a specific use of the term Embodied energy. Indeed, at the time they xe unable to identify them. Exactly what this is in nature is still uncertain, as it is a new concept. Research, Past and Present, with Bruno D.

In the s in the latter part of his career H. Odum developed an analogue of Ohm’s Law which aimed to be a representation of energy flows through ecosystems.

His dissertation was titled The Biogeochemistry of Strontium: Electron flow in the electrical network represented the flow of material e. Views Read Edit View history. 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 used simple electrical networks ds of batteries, wires, resistors and capacitors as models for ecological systems.

The analogous concept required is the biomass activity, that is, the thermodynamic thrust, which may be linear. Odum described his role as follows: This was described variously as the “maximum power principle” Odum”maximum power theory” Oodum”maximum power efficiency” Costanzap.

If the symbols are understood by all, the process of discussion and drawing unites people and thinking around a task with a minimum of semantic problems about meanings. Environment, Power, and Society. Ecological economicsecological engineeringemergymaximum power principlesystems ecology.

Howard T. Odum

He classified water bodies based on their P-R ratios, this separated autotrophic from heterotrophic ecosystems: In a controversial move, Odum, together with Richard Pinkerton at the time physicist at the University of Floridawas motivated by Alfred J. The reason that systems can not proceed toward some kind of disintegration is that such a pattern has no mechanism of maintaining itself.


Such a consideration led Odum to ask two important methodological questions: It presented a cogent argument for the limits of industrial growth. Odum left a large legacy in many fields associated with ecology, systems, and energetics. However this principle has only been demonstrated in a few experiments [38] and is not widely recognized in the scientific community.

For the American sociologist, see Howard W. He said that the “human is the biosphere’s programmatic and pragmatic information processor for maximum performance”.

For Odum, as a large entity, the world constituted a revolving cycle with high stability. Some consider the concept of “emergy”, sometimes briefly defined as “energy memory”, as one of Odum’s more significant contributions. For Hall [45] the importance of Odum’s work came through his integration of systems, ecology, and energy with economics, together with Odum’s view that economics can be evaluated on objective terms such as energy rather than on a subjective, willingness to pay basis.

In this way he was able to establish the stream’s energy budget”. The Ideas and Applications of H. Retrieved from ” https: In this model energy and matter flows through an ecosystem: Kitching claimed that the language was a direct result of working with analogue computers, and reflected an electrical engineer’s rcologia to the problem of system representation:
