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. 1998-11-05 · Metapopulation biology is concerned with the dynamic consequences of migration among local populations and the conditions of regional persistence of species with unstable local populations. Well By forcing metapopulation dynamics on a formerly heterogeneous (but stable within subpopulations) population, the probability of simultaneous extinction of all subpopulations actually increases. Thus, it cannot be automatically assumed that increasing matrix quality will lower the probability of global extinction of a population.

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 ecology is a key concept in conservation ecology. Although pure metapopulations may be rare, there are many empirical studies in which metapopulation processes, Metapopulation Ecology RESEARCH APPROACH A metapopulation is a “population of populations” distributed in discrete habitat patches that are linked by occasional dispersal.

av V Johansson · 2012 · Citerat av 1 — A metapopulation consists of a single species inhabiting a network of spatially separated habitat patches that are connected by dispersal. Therefore, the species is more likely to occur in a large and well-connected patch compared to a small and isolated one.

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.

The spatiotemporal patterns of local extinctions and patch recolonizations create a shifting distribution of populations among patches. The kind of metapopulation approach depicted in Fig. 1 does not include everything that is commonly assigned to metapopulation ecology. Other approaches have been reviewed, for instance theore-tical work based on lattice models6,7,11–13 and conservation-oriented empirical studies14–16. The term ‘metapopulation’ is often used for Metapopulation ecology remains one of the most dynamic and active areas of population ecology! Broadly speaking, a metapopulation is just a spatially structured population.

It encompasses both the essential theory of metapopulations and a wide range of empirical studies - including the author's own unique research on the metapopulation biology of the Metapopulation ecology is used in conservation biology and in population genetics where it influences genetic structure, the rate and trajectory of evolution and even what traits are under selection. Finally, communities of species that are distributed in a landscape potentially form metacommunity, which is a concept that shares important characteristics with metapopulations. The metapopulation biology and evolutionary ecology of these bacterial systems, in these synthetic ecosystems, can be addressed using experimental biophysics.
