What is Organization-Environment Coevolution?
It requires that all changes in all interacting organizations result from direct and indirect feedback. An organization that stimulates the evolution of another organization is, in turn, itself responsive to that evolution, and the response is predictable. In direct coevolution, two populations evolve in response to each other. In diffuse coevolution, one or more populations evolve in response to several other organizations in a community. In some situations there may be standard evolution as well. Coevolution implies nonlinear feedback among interacting populations. Why Study Coevolution? It is potentially more applicable in complex situations. An Application to Coevolution in Ecological Communities Community level interactions moderate population dynamics by altering selection pressures. Coevolution in Ecological Communities The instantaneous rate of population change dN/Dt = rN(1-N/K) where r is growth rate, N is population size, and K is carrying capacity. Over time the population
