Organizational ecology (also organizational demography and the population ecology of organizations) is a theoretical and empirical approach in the social sciences that is considered a sub-field of organizational studies. Organizational ecology utilizes insights from biology, economics, [ 1] and sociology, and employs statistical analysis to try ...

Source–sink dynamics. 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.
A metapopulation consists of a group of spatially separated populations of the same species which interact at some level. The term metapopulation was coined by Richard Levins in 1969 to describe a model of population dynamics of insect pests in agricultural fields, but the idea has been most broadly applied to species in naturally or ...

Doctoral advisors. Bernard Stonehouse. Robert Sidney Bigelow. Graeme James Caughley FAA (28 September 1937 – 16 February 1994) was a New Zealand population ecologist, conservation biologist, and researcher. He combined empirical research with mathematical models, and supported the declining population paradigm.
Ecology. Garrett James Hardin (April 21, 1915 – September 14, 2003) was an American ecologist and microbiologist. He focused his career on the issue of human overpopulation, and is best known for his exposition of the tragedy of the commons in a 1968 paper of the same title in Science, [ 1][ 2][ 3] which called attention to "the damage that ...
