Although applying evolutionary theory to questions about ecosystem structure and function is not simple, it is essential. For example, certain hypotheses of ecosystem optimality seem to require the operation of group selection or coevolution at levels above the individual. Such assumptions should not go untested, and an examination of evolutionary mechanisms in an ecosystem context could lead to new insights. Explaining ecosystem properties that are clearly additive or collective in terms of… 
A persistence enhancing propensity account of ecological function to explain ecosystem evolution
It is argued that ecosystems, by forming more or less resilient assemblages, can evolve even while they do not reproduce and form lineages, and a Persistence Enhancing Propensity account of role functions in ecology is proposed to account for this overlap of evolutionary and ecological processes.
Artificial-Life Ecosystems - What are they and what could they become?
It is argued a position that the inclusion of low-level representations of energetics, matter and evolution, in concert with pattern-oriented modelling techniques from Ecology for model validation, will improve the relevance of A-Life models to Ecology.
Phyllosphere Ecology in a Changing Environment: The Role of Insects in Forest Ecosystems
A major challenge to understanding the role of species in ecosystems (Lawton 1994) is to collect and filter those pieces of information from different levels of organization that are likely to affect
Trends in the evolution of ecology: “Spain is different”
The importance of historical factors on the development of paradigms of ecology, and the special case of Spain, likely due to the influence of pioneers working in oceanography, limnology and geography is discussed.
Patterned Process in Biological Evolution
Evolutionary theory has influenced the development of metaphysics by making logical room for a non-essentialist conception of biological species and an explanation for the process of speciation that does not resort to the metaphysics of formal and final causation.
Limits on ecosystem trophic complexity: insights from ecological network analysis.
It is suggested that several whole-system processes may be at play in generating these ecosystem limits and regularities, and an upper bound on the number of effective trophic levels at about 3-4 links is suggested.
It is demonstrated that the extended phenotype can be traced from the individuals possessing the trait, to the community, and to ecosystem processes such as leaf litter decomposition and N mineralization, which provides a genetic framework for community structure and ecosystem processes.
Global climate change and the evolutionary ecology of ecosystem functioning
  • O. Schmitz

  • 2013
This work sketches out one framework that shows how increases in animal metabolic rates in response to thermal stress lead to phenotypically plastic shifts in animal elemental demand, from nitrogen‐rich proteins that support production to carbon‐rich soluble carbohydrates that support elevated energy demands.


A Hierarchical Concept of Ecosystems.
"Ecosystem" is an intuitively appealing concept to most ecologists, but, in spite of its widespread use, the term remains diffuse and ambiguous. The authors of this book argue that previous attempts

Constraints on the Evolution of Mutualisms

A brief discussion of pollination and seed dispersal suggests checks to mutualistic coevolution, and indicates that reciprocal adaptation, where it occurs, is general rather than specific.
How to Carry Out the Adaptationist Program?

Even though the adaptationist program has been occasionally misapplied, particularly in an uncontrolled reductionist manner, its heuristic power justifies its continued adoption under appropriate safeguards.
Systems ecology : an introduction
An integrated theoretical and applied introduction to systems ecology that uses energy diagrammatic language to explain basic concepts of systems, modelling, and simulation. Teaches energetics while
A Critical Review of the Models of Group Selection
  • M. Wade

  • 1978
It is shown that the models have a number of assumptions in common which are inherently unfavorable to the operation of group selection, and alternative assumptions derived from the empirical results are suggested and discussed in the hope that they will stimulate further theoretical and empirical study of this controversial subject.
