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 population to another.
Model assumptions: Metapopulation models • Homogenous patches • No spatial structure • No time lags • Large number of patches. Metapopulations The development of metapopulation models has lead to research on: • How to estimate factors that influence patch colonization and extinction. • Importance of the spatial arrangement of suitable patches. • Extent to which the landscape between habitat patches affects dispersal Such a collection of interacting populations of the same species is called a metapopulation. Each distinct population in a metapopulation may be referred to as a subpopulation, a local population, or simply as a population. Metapopulation dynamics. Populations of many species like the Mountain Sheep (see figure) occupy patches of high quality habitat and use the intervening habitat only for movement from one patch to another. A metapopulation is generally considered to consist of several distinct populations together with areas of suitable habitat which are currently unoccupied. Although the term metapopulation had not yet been coined, the environmental factors of spatial heterogeneity and habitat patchiness would later describe the conditions of a metapopulation relating to how groups of spatially separated populations of species interact with one another. Metapopulation theory was first developed for terrestrial ecosystems, and subsequently applied to the marine realm. Although the term metapopulation had not yet been coined, the environmental factors of spatial heterogeneity and habitat patchiness would later describe the conditions of a metapopulation relating to how groups of spatially separated populations of species interact with one another.

A metapopulation consists of a group of spatially separated population s of the same species which interact at some level. Metapopulation s. Spatial ana lysis of ecological systems often reveals that assumptions that are valid for spatially homogenous population s-and indeed, intuitive-may no longer be valid when migratory subpopulations moving from one patch to another are considered. Metapopulations in the Context of Patch Dynamics. A metapopulation is a population of populations (Levins 1969,1970); in which distinct subpopulations (local populations) occupy spatially separated patches of habitat. Local population turnover and inter-patch colonization are two dominant forces influencing metapopulation dynamics (Wu 1994), indicating that the movement of organisms between patches is a key aspect of metapopulation dynamics and persistence (Hanski 1985, Gustafson and Gardner 1996, Weins 1996, Cronin 2003). A metapopulation is a population of populations, or a group of groups, that is made up of the same species. Each subpopulation, or subgroup, is separated from all other subpopulations, but movement of individuals from one population to another occurs regularly. Metapopulation Theory. Metapopulation theory states that a large population consisting of a single species is most stable over a large area when it is divided up into smaller subpopulations. These subpopulations take advantage of small, local environments, like your backyard or the park down the street.
