a group of subpopulations each isolated in a patch of habitat. The persistence of the metapopulation is dependent on the persistence of the subpopulations and movement of animals among subpopulations to exchange genes.
A population divided into subpopulations, among which there are occasional exchanges of individuals.
A network of semi-isolated populations with some level of regular or intermittent migration and gene flow among them, in which individual populations may be extinct by them be colonized from other populations.
spatially separated subpopulations of wildlife that are separated by geography and linked by dispersal.
A population perceived to exist as a series of subpopulations, linked by migration between them. However, the rate of migration is limited, such that the dynamics of the metapopulation should be seen as the sum of the dynamics of the individual subpopulations.
a collection of semi-isolated populations that interact via dispersal and gene flow
a collection of subpopulations
a population of source and sink populations
a population that occupies several geographically separated habitat patches
a population which consists of several subpopulations linked together by immigration and emigration
a self-contained, and self-sustaining, group of smaller, interconnected animal populations
a spatially fragmented population, comprising sub-populations that occasionally interact through pollination or seed-dispersal
a collection of populations of the same species that interact through exchange of individuals, or dispersal
A subdivided population of a single species. metastasis(meh- tas-teh-sis) The spread of cancer cells beyond their original site.
multiple populations of an organism within an area in which interbreeding could occur, but does not due to geographic barriers.
A group of populations of the same species that exist at the same time but in different places.
A set of partially isolated populations belonging to the same species. The different populations are able to exchange individuals and recolonize sites in which the species has recently become extinct.
A set of local populations connected by migrating individuals.
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 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.
