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.

Model description. General According to Levins' original definition, a metapopulation is "a population of local populations within the metapopulation by means of dispersal from other local For example, population growth rates of many bird species are closely correlated with nest preda- tion (Newton 1998), meaning artificial nest experiments.

Metapopulation 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 1970 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.

2004:3 av L Sundqvist · 2016 · Citerat av 1 — A structured population can be referred to as a metapopulation, di- vided into partly isolated subpopulations (Levins, 1969). Understanding both the life history of a species and its environment is important when interpreting data on its genetic structure. En metapopulation är en population av populationer.

Each subpopulation, or subgroup, is separated from all other subpopulations, but movement In this chapter, we restrict the term metapopulation to its original meaning (Levins, 1969, 1970): a set of local populations that persists in a balance between stochastic local extinctions and establishment of new local populations (Hanski and Gilpin, 1991). A critical element in the metapopulation concept thus defined is the notion that the long-term persistence of a metapopulation cannot be explained by the regulation and consequent persistence of local populations.

In this paper, we revisit the metapopulation dynamics model of typical Levins type, On parle de métapopulation pour désigner un ensemble de populations d'une même espèce, séparées par des barrières géographiques, entre lesquelles il existe des échanges (flux de gènes metapopulation theory remains largely untested in the field. This thesis investigates the importance of metapopulation structure in the ‘real world’, firstly by building additional realism into metapopulation models, and secondly through a 3-year field study of a real metapopulation system. Metapopulation and metacommunity theories occupy a central role in ecology, but can be difficult to apply to plants.
