En metapopulation är ett ekologiskt begrepp för system av lokala populationer av samma art som är rumsligt åtskilda. De lokala populationerna är så små att de löper en viss risk att dö ut, men de lokala utdöendena kompenseras av att nya lokala populationer uppstår genom kolonisationer.

A framework of habitat patches within a less-suitable matrix describes a metapopulation. Metapopulation analysis can provide insight into the dynamics of each Metapopulation models describe how the spatial distribution of patches affects colonization and extinction, but often do not account for the heterogeneity in the landscape between patches. Models in landscape ecology use detailed descriptions of landscape structure, but often without considering colonization and extinction dynamics.

Metapopulation · A metapopulation consists of a group of spatially separated populations of the same · A metapopulation is generally considered to consist of

The metapopulation persists if λ M > δ, where δ = μ/c and λ M, called the metapopulation capacity, is the leading eigenvalue of a landscape or metapopulation matrix M [4,5].

Run the model with the default values. A metapopulation is a “population of populations” distributed in discrete habitat patches that are linked by occasional dispersal. Rather than track individual organisms through time, a metapopulation approach tracks the occupancy of habitat patches through time. At equilibrium p* = 1 - e/m. The metapopulation will persist (i.e., p* > 0) only if e < m. The Levins concept and model has become the classical metapopulation.

Populations outside of a network of connected populations either exist as isolated populations or belong to a separate metapopulation. 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. Metapopulation metapopulation threshold conditions for a similar spatially realistic system.

Information on the African - African American Metapopulation. The African American Metapopulation (African - African American) consists of 13226 haplotypes (at least minimal) and 28 unique population samples. From the Cambridge English Corpus. As a result, the genetic variance in this metapopulation is likely to be less than in an undivided population. From the Cambridge English Corpus.
