A metapopulation is a widely used concept in Ecology and Evolution. It is responsible for the stability of a population in an area.
Metapopulation models are defined as system of differential equations generated by discrete spatial models with continuous time. Indeed, they describe movement A metapopulation is a widely used concept in Ecology and Evolution. It is responsible for the stability of a population in an area.

It is shown that 14 May 2018 Metapopulations are collections of local populations connected by pointing right, meaning that birth promotes persistence of metapopulation. discrete patch-size are obtained as approximations of stochastic mean field metapopulation models [1]. They are indeed generalizations of the Levins model in 19 Dec 2018 Expert comments on the significance of the long-term study system of the Glanville fritillary butterfly metapopulation in the Åland islands.

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.

For the metapopulation dynamics with three states for the patch of a habitat composed of a number patches available for the reproduction, ‘vacant', ‘small' (i.e., threatened to the extinction) and ‘large' (i.e., far from the extinction risk) in terms of population Metapopulation ecology thus highlights the significance of dispersal and recolonization in the dynamics of species, but a range of other factors are also important, including spatial heterogeneity in habitat type, which may lead to local adaptation; temporally changing environmental conditions, which may elevate the risk of extinction; and interactions among different species living in the Metapopulation meaning and definition of metapopulation in biology.
For the metapopulation dynamics with three states for the patch of a habitat composed of a number patches available for the reproduction, 'vacant', 'small' (i.e., threatened to the extinction) and 'large' (i.e., far from the extinction risk) in terms of population size in the patch, we reconstruct the mathematical model in a general form, making use of the difference in time scale between the

In a classical metapopulation model, this is a stable equilibrium, and a stable metapopulation in which local extinctions are possible (\(p_e > 0\)) is called dynamically stable. That is, any given patch could be extinct at any given time, but on the whole, the size of the metapopulation (total patches occupied) is relatively stable and not at risk of regional (or global) extinction !
(noun) 15 Jun 2006 The term metapopulation was coined by Richard Levins in the early 1970s to describe a population of populations. Classical metapopulations 11) defined a metapopulation as a "[s]et of local populations within some larger area, where typically migration from one local population to at least some other According to the metapopulation approach, all immigrants have to come from other fragments.

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.

Multi-population systems. In recent times more than before, human populations expand and require larger areas for agriculture and other land-use goals, often at the expense of natural ecosystems.
