I en metapopulation är vissa delpopulationer, s.k. ”sources”, mer livskraftiga om den gotländska populationen av brushane kan anses som en metapopulation,

Metapopulation ecology is used in conservation biology and in population genetics where it influences genetic structure, the rate and trajectory of evolution and even what traits are under selection. Finally, communities of species that are distributed in a landscape potentially form metacommunity, which is a concept that shares important characteristics with metapopulations.

SAMENVATTING(SUMMARY INDUTCH) 195 DANKWOORD 203 CURRICULUM VITAE 205 The kind of metapopulation approach depicted in Fig. 1 does not include everything that is commonly assigned to metapopulation ecology. Other approaches have been reviewed, for instance theore-tical work based on lattice models6,7,11–13 and conservation-oriented empirical studies14–16. The term ‘metapopulation’ is often used for The establishment and spread of a disease within a metapopulation is influenced both by dynamics within each population and by the host and pathogen spatial processes through which they are connected. We develop a spatially explicit metapopulation model to investigate how the form of host and diseas … ConservationMethods Using metapopulation theory for practical conservation of mangrove endemic birds Ryan Huang , 1∗ Stuart L.

As a result, the genetic variance in this metapopulation is likely to be less than in an undivided population. From the Cambridge English Corpus. 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.

“Set of local populations occupying an array of habitat patches and linked by the movements of individuals” Movement: emigration Aug 16, 2017 What is a Metapopulation? Richard Levins developed the concept of a metapopulation to describe “a population of populations”. More specifically Jan 14, 2008 Abstract. This paper outlines a conceptual and theoretical framework for single- species metapopulation dynamics based on the Levins model May 23, 2012 The metapopulation concept was established in the literature in the late 1960s, though some ecologists had formulated ideas about spatially Jan 5, 2021 Two necessary features of a metapopulation have already been established here that individual subpopulations have a realistic chance of En metapopulation är ett ekologiskt begrepp för system av lokala populationer av samma art som är rumsligt åtskilda.

Metapopulations characteristically demonstrate a turnover of local populations going extinct and becoming re-established, resulting in a distribution pattern that Ecology: Graduate Level; Meta-Population: - Concept of Metapopulation.- Dynamics of Metapopulation- Conditions for definition.- Types of metapopulation- Habi By forcing metapopulation dynamics on a formerly heterogeneous (but stable within subpopulations) population, the probability of simultaneous extinction of all subpopulations actually increases. Thus, it cannot be automatically assumed that increasing matrix quality will lower the probability of global extinction of a population. Pris: 729 kr. Häftad, 1997. Skickas inom 10-15 vardagar.

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. 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 Metapopulation dynamics are influenced by four kinds of stochasticity (Table 1): demographic and environmental stochasticity affecting separately each local population, and extinction–colonization and regional stochasticity affecting the entire metapopulation.

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. Populations outside of a network of connected populations either exist as isolated populations or belong to a separate metapopulation.
