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 artificially fragmented habitats. In Levins' own words, it consists of "a population of populations".

Metapopulation ecology is a field that is richer in theory than in empirical results. Many existing empirical studies use an incidence function approach based on spatial patterns and key assumptions about extinction and colonization rates.

La métapopulation est un concept écologique qui définit un ensemble de populations risque élevé d'extinction. Il est aussi appelé patch occupancy model. We used the results from a stochastic population dynamics model of South Texas bobwhites as conceptual justification for use of metapopulation theory in. Metapopulation biology is concerned with the dynamic consequences of migration among metapopulation extinction (applying theory developed for single. 12.4. Metapopulation models. Metapopulation is a set of local populations connected by migrating individuals.

Metapopulation theory

For a given species, each metapopulation is continually being modified by increases (births and immigrations) and decreases (deaths and emigrations) of individuals, as well as by the emergence and dissolution of local populations contained within it. Metapopulation theory is largely based on a dynamic aspect of population maintenance that embraces a regional perspective (Levins, 1970). Generally the equilibrium, or strictest, view embraces a balance between periods of extinction and colonization, with migration between patches. Metapopulation: Metapopulation is a population in which individuals are spatially distributed in a habitat in two or more subpopulations. Populations of butterflies and coral-reef fishes are good examples of metapopulation. Metapopulation are composed of discrete subpopulations 2. Some degree of migration 3.

In information theory, the measure of unexpected difference (from a base expectation) is called entropy. Compared with the 2nd law of thermodynamics, the

The manner in which patches are delineated in spatially realistic metapopulation models will influence the size, connectivity, and extinction and recolonization dynamics of those patches. Most commonly used patch‐definition methods focus on identifying discrete, contiguous patches of habitat from a single temporal observation of species occurrence or from a model of habitat suitability.

in metapopulation theory, what does P stand for. proportion of patches occupied. which of the following factors is related to patch colonization. isolation of the patch.

Many existing empirical studies use an incidence function approach based on spatial patterns and key assumptions about extinction and colonization rates. Theory suggests that the risk of extinction by mutation accumulation can be comparable to that by environmental stochasticity for an isolated population smaller than a few thousand individuals. Here we show that metapopulation structure, habitat loss or fragmentation, and environmental stochasticity can be expected to greatly accelerate the accumulation of mildly deleterious mutations It was concluded that metapopulation theory did not provide a very satisfactory explanation for the changes in the helminth communities in eels and reasons for this included the inherent difficulty of applying metapopulation theory to parasites and the fact that the helminth communities in eels in the River Exe were atypical in being dominated by eel specialists.

Metapopulation theory identifies biogeographical patterns among core and satellite marine bacteria scaling from tens to thousands of kilometers. Metapopulation theory has become a common framework in conservation biology and it is sometimes suggested that a metapopulation approach should be used for management of large mammals. However, it has also been suggested that metapopulation theory would not be applicable to species with long generations compared to those with short ones.
