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 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. In this model, organisms occupy two ...
Theoretical ecology aims to explain a diverse range of phenomena in the life sciences, such as population growth and dynamics, fisheries, competition, evolutionary theory, epidemiology, animal behavior and group dynamics, food webs, ecosystems, spatial ecology, and the effects of climate change. Theoretical ecology has further benefited from ...
In population ecology and economics, optimum sustainable yield is the level of effort (LOE) that maximizes the difference between total revenue and total cost. Or, where marginal revenue equals marginal cost. This level of effort maximizes the economic profit, or rent, of the resource being utilized. It usually corresponds to an effort level ...
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.
Ecosystem management. Prescribed burning is a technique used in ecosystem management. This indirectly benefits society via the maintenance of ecosystem services and the reduction of severe wildfires. Ecosystem management is an approach to natural resource management that aims to ensure the long-term sustainability and persistence of an ...
PVA is also used to identify factors that drive population dynamics, compare proposed management options and assess existing recovery efforts. [2] PVA is frequently used in endangered species management to develop a plan of action, rank the pros and cons of different management scenarios, and assess the potential impacts of habitat loss.
