According to Aldrich and Pfeffer (1976), the population-ecology model does not deal with single organization units but is concerned with forms or populations of organizations. Although pure metapopula-tions may be rare, there are many empirical stud-ies in which metapopulation processes, primarily local colonisation and extinction, have been useful in explaining dynamics of natural, managed and experimental systems. Condorcet, and Other Writers. Introduction to the Science of Ecology 2.
