Interpopulation Processes: Community Level

Hawley’s (1950) classic statement on human ecology emphasized community succession, as interdependent populations are sorted out by processes of competition, domination, and differentiation (see Astley & Fombrun, 1987). Analytically, a series of “stages” may be distinguished, but in practice, community succession is on-going and many different processes are occurring simultaneously. Within populations, competition pushes organizations toward adopting similar forms, eventually resulting in greater homogeneity. Across populations, dominant populations drive others into positions of subordination and ancillary roles, resulting in community-level differentiation.

Classic industrial evolution models, such as Stigler (1951), argued that vertical disintegration – with increasing specialization upstsream and downstream – occurs as markets expand. Thus, we would expect specialists to emerge in populations after some early period of expansion. Or, perhaps it is better to say, new populations to emerge. Ecological theory, by contrast, has focused more on horizontal relations – competitive interdependence – and so has relatively neglected developments in symbiotic relations and interpopulation dynamics, with a few exceptions, which we point out below.
