Images for Metapopulation Definition Metapopulation types proposed by Harrison and Taylor We propose a general framework for population viability analysis aimed at near-term ecological forecasting of suitable focus species’ presence in heterogeneous landscapes. Our method is based on remotely acquired and objectively manipulated Earth observations, coupled with hard-gained field evidence and landscape-explicit stochastic models of population dynamics. The integration of field In this paper, we revisit the metapopulation dynamics model of typical Levins type, and reconsider its mathematical modeling.

The metapopulation approach Metapopulations persist due to the balance between extinction and colonization of local populations. In contrast to the IFD, each population in a patch has its own local dynamics, which are not dependent on the state of other patches as in structured populations, nor on immigration from other patches as sink-populations do.

The rate of change in occupied habitat patches is a function of colonization rates (c) and extinction rates (e) as shown in Equation 5.2 (Levins 1969). 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.

Metapopulation meaning






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.

In its "classical" form (Levins 1969), a metapopulation consists of   The manner in which patches are delineated in spatially realistic metapopulation models will influence the size, connectivity, and extinction and recolonization  A metapopulation consists of a group of spatially separated populations of the same species which interact at some level.

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

Many organisms have to face large-scale habitat destruction and fragmentation of larger populations. CONCEPTUALDOMAINAND METAPOPULATIONAPPROACHES A fundamental assumption of the original metapopulation concept (Levins, 1969a) is that space is discrete and that it is possible and useful to distinguish between habitat patches that are suitable for the focal species and the rest of the environment, often called the matrix. The Levins or classical metapopulation.
