Metapopulation Ecology - Ilkka Hanski - Häftad - Bokus
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. 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. Metapopulation Ecology presents a comprehensive synthesis of current research in this rapidly expanding area of population biology, from an author who is world-famous for his ground-breaking work on metapopulations.

Therefore, the species is more likely to occur in a large and well-connected patch compared to a small and isolated one. av J Hedin · 2003 · Citerat av 28 — Abstract: This thesis starts with a review of different biodiversity assessment methods in forests and the rest deals with the metapopulation ecology of LIBRIS titelinformation: Metapopulation ecology of Osmoderma eremita : dispersal, habitat quality and habitat history / Jonas Hedin.

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.

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.
