Ecosystems and other self-organizing systems develop system designs and mathematics that reinforce energy use, characteristically with alternate pulsing of production and consumption, increasingly recognized as the new paradigm. Insights from the energetics of ecological food chains suggest the need to redefine work, distinguishing kinds of energy with a new quantity, the transformity (energy of one type required per unit of another). Transformities may be used as an energy-scaling factor for… Expand

Howard Odum’s “Self-organization, transformity and information”: Three decades of empirical evidence
The Biosphere is self-organized into a hierarchy of energy transformations. More dilute forms of energy (e.g. solar energy) are concentrated in biological structures and through socioeconomicExpand
Maximum (em)power: a foundational principle linking man and nature
Abstract Hypothesized as a universal principle of system self-organization, selection for maximum power provided the basis for H.T. Odum’s systems-based understanding of energy transformationExpand
Thermodynamics-based categorization of ecosystems in a socio-ecological context
TLDR
An input-state-output description of ecosystems in a socio-ecological context is presented which leads to a characterization in 8 categories, in order to provide a new contribution to systems ecology. Expand
Energy hierarchy and landscape sustainability
TLDR
Two principles of energetic hierarchy for landscape sustainability are proposed: first, the landscape must be arranged spatially according to its energy hierarchy, and second, a sustainable landscape must comprise a hierarchy of self-organizing ecosystems that can enable the systems to maximize useful power at all levels of the energy hierarchy.

Energy and sustainability in a complex world: Reflections on the ideas of Howard T. Odum
The late Howard T. Odum (1924-2002), the renowned American ecologist and systems analyst, viewed thermodynamic constraints as limiting the development of self-organizing biological organisms. In workExpand
The prosperous way down
Principles that appear to govern all systems including human societies were used to consider the time of economic descent ahead. These include the energy laws, the emergy concept, the maximum empowerExpand
Evolution in thermodynamic perspective: An ecological approach
TLDR
This thermodynamic approach to evolution frees evolutionary theory from dependence on a crypto-Newtonian language more appropriate to closed equilibrial systems than to biological systems, and drives a conceptual wedge between functions of artifacts and functions of natural systems. Expand
Network integration of ecological extremal principles: exergy, emergy, power, ascendency, and indirect effects
Abstract Self organization in ecosystems has been postulated to be directed by a number of seemingly unrelated goal functions or extremal principles. These include exergy , the useful work content ofExpand
The World-System and the Earth System Struggles with the Society / Nature Binary in World-Systems Analysis and Ecological
Efforts to conceptualize the role of asymmetric resource transfers in the capitalist world-system have been constrained by the emphasis on surplus value and the labor theory of value in MarxistExpand
Ecosystem flow analysis
Ecosystem services provide the basis for all human activity. Maintaining their sustained function is of critical concern as the issues of sustainability addressed here in this encyclopedia areExpand

TLDR
The principles of ecological succession bear importantly on the relationships between man and nature and needs to be examined as a basis for resolving man’s present environmental crisis. Expand
Mechanisms of Succession in Natural Communities and Their Role in Community Stability and Organization
TLDR
In the majority of natural communities succession is frequently interrupted by major disturbances, such as fires, storms, insect plagues, etc., starting the process all over again, but if not interrupted, it eventually reaches a stage in which further change is on a small scale as individuals die and are replaced.
