Nevertheless, a metapopulation approach to conservation biology is likely to provide a useful tool for developing management strategies as it addresses genetic, For those species to avoid regional extinction in fragmented landscapes, they must undergo some kind of metapopulation dynamics so that local extinctions are 3. Metapopulation is known as “Population of population” A metapopulation is a group of same individual living in different places forming “patches” , but Nov 15, 2010 A. Metapopulation: set of local populations occupying various habitat patches and connected to one another by the movement of individuals In metapopulation models, local populations, interact via immigration and emigration. Example: Checkerspot butterfly in SF bay area.

We believe the concept of the metapopulation and metapopulation dynamics may provide insights into the persistence and conservation of species faced with habitat fragmentation as a consequence of military training or other land use (see Predicting the results of training and land management actions).

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. Notice that the latter two forms of stochasticity are analogous to demographic and A metapopulation is a group of populations that are separated by space but consist of the same species. These spatially separated populations interact as individual members move from one Metapopulation structure assumed in the Levins model (1969): a large network of similar small patches, with local dynamics occurring at a much faster time scale than metapopulation dynamics; in a broader sense used for systems in which all local populations, even if they may differ in size, have a significant risk of extinction. 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 .

A framework of habitat patches within a less-suitable matrix describes a metapopulation. Metapopulation analysis can provide insight into the dynamics of each a. the basic metapopulation model b. the basic subpopulation model c. the source-sink metapopulation model d. the landscape metapopulation model.

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.

A metapopulation is simply a population of patches , each of which may or may not be occupied by a species of interest at a given point in time. Metapopulations are conceived as spatially structured populations consisting of distinct units (subpopulations), separated by space or barriers, and connected by dispersal movements. 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.
