The first explicit formulation of a theory of population ecology, by Michael T. Hannan and the late John H. Freeman in their 1977 American Journal of Sociology piece "The population ecology of organizations" and later refined in their 1989 book Organizational Ecology, examines the environment in which organizations compete and how a process ...
Population ecology is a sub-field of ecology that deals with the dynamics of species populations and how these populations interact with the environment. [15] It is the study of how the population sizes of species living together in groups change over time and space, and was one of the first aspects of ecology to be studied and modelled mathematically.
Source–sink dynamics is a theoretical model used by ecologists to describe how variation in habitat quality may affect the population growth or decline of organisms.. Since quality is likely to vary among patches of habitat, it is important to consider how a low quality patch might affect a population.
A population ecology concept is r/K selection theory, one of the first predictive models in ecology used to explain life-history evolution. The premise behind the r/K selection model is that natural selection pressures change according to population density. For example, when an island is first colonized, density of individuals is low.
Consider a population at harvested at a constant harvest level . If the population falls (due to a bad winter or illegal harvest) this will ease density-dependent population regulation and increase yield, moving the population back to , a stable equilibrium. In this case, a negative feedback loop creates stability.

The conceptual roots of organizational adaptation borrows ideas from organizational ecology, evolutionary economics, industrial and organizational psychology, and sociology. A systematic review of 50 years worth of literature defined organizational adaptation as "intentional decision-making undertaken by organizational members, leading to ...
