Metapopulation ecology

Metapopulation ecology is a key concept in conservation ecology. Although pure metapopulations may be rare, there are many empirical studies in which metapopulation processes, primarily local Metapopulation Ecology Saskya van Nouhuys, University of Helsinki, Helsinki, Finland A metapopulation is a spatially structured population that persists over time as a set of local populations in balance between local extinction and colonization. Starting in 1969, and accelerating since the early 1990s, mathematical models of metapopulations 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 Metapopulation dynamics have emerged as a key consideration in conservation planning for salmonid fishes. Implicit to many models of spatially structured populations is a degree of synchrony, or Metapopulation Ecology Saskya van Nouhuys, University of Helsinki, Helsinki, Finland A metapopulation is a spatially structured population that persists over time as a set of local populations in balance between local extinction and colonization. Starting in 1969, and accelerating since the early 1990s, mathematical models of metapopulations The metapopulation biology and evolutionary ecology of these bacterial systems, in these synthetic ecosystems, can be addressed using experimental biophysics.

Metapopulation ecology is such a framework. It was introduced by Levins, 1969 to explain the persistence of agricultural pests across a set of habitat patches, such as crop fields, and refined by Hanski to account for the characteristics of patches, such as their size, and the connectivity between them ( Hanski, 1998 ; Hanski, 1994 ).

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 local populations contained within it.

Metapopulation dynamics may contribute to the development of landscape ecology by emphasizing the dynamics that occur in a landscape. The spatiotemporal patterns of local extinctions and patch recolonizations create a shifting distribution of populations among patches. Metapopulation ecology and landscape ecology aim to understand how spatial structure influences ecological processes, yet these disciplines address the problem using fundamentally different modeling approaches. The population dynamics and ecology of the red—spotted newt were studied from 1974 to the present in a series of mountain ponds in the Shenandoah Mountains, Virginia. Adult and juvenile newts were censused using a combination of methods, including drift fences and dip—netting. The source-sink model of population dynamics has made contributions to many areas in ecology. For example, a species' niche was originally described as the environmental factors required by a species to carry out its life history, and a species was expected to be found only in areas that met these niche requirements.
