Metapopulation dynamics The theory is very simple. The world is divided up into many patches, all of which are potentially habitable. Populations on inhabited
Departments of Entomology and Biology, Pennsylvania State A toxicant‐dosed metapopulation model was used to explore the range of possible dynamics of populations in contaminated field sites. A single species metapopulation model was developed that is discrete, deterministic, and incorporates doseresponse curves and biotic growth rates to describe the effects of contamination on a metapopulation. Metapopulation theory provides a framework for understanding population persistence in fragmented landscapes and as such has been widely used in conservation biology to inform management of fragmented populations. However, classical metapopulation theory [Levins, R. (1970) Lect. Notes Math. 2, 75-107] ignores metapopulation structure and local population dynamics, both of which may affect demonstrate the importance of metapopulation dynamics and landscape con-nectivity for the persistence of populations in fragmented landscapes. The observation that locally abundant species tend to be widespread, whereas locally rare species tend to be narrowly distributed, is one of the most pervasive patterns in ecology (1–3).

Source–sink dynamics has also been incorporated into studies of metapopulations, a group of populations residing in patches of habitat. Though some patches may go extinct, the regional persistence of the metapopulation depends on the ability of patches to be re-colonized.
In the context of metapopulation dynamics, generalists are expected to have higher landscape-scale occupancy than specialists, which leads to higher connectivity and higher colonization
Our research explores these sorts of ecological dynamics using mathematical tools, species record databases and experimental approaches. Metapopulation studies have important conceptual links with the equilibrium theory of island biogeography and with studies on the dynamics of species living in patchy environments. Metapopulation ideas play an increasingly important role in landscape ecology and conservation biology. 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 artificially fragmented habitats.

In set-aside stands Metapopulation, in ecology, a regional group of connected populations of a species. 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. Source–sink dynamics has also been incorporated into studies of metapopulations, a group of populations residing in patches of habitat. Though some patches may go extinct, the regional persistence of the metapopulation depends on the ability of patches to be re-colonized.
Such a collection of populations and its dynamics is called metapopulation dynamics.

Metapopulation dynamics. Metapopulation biology is concerned with the dynamic consequences of migration among local populations and the conditions of regional persistence of species with unstable local populations. Well established effects of habitat patch area and isolation on migration, colonization and population extinction have now become
