Metapopulation theory

av E Degerman · 2013 — I vilken utsträckning funktionen som metapopulation ansvarar för vidmakthållandet av Testing predictions of stream landscape theory for fish assemblages in In this context we do not use metapopulation in its strictest sense that requires the extinction and The applicability of metapopulation theory to large mammals. International Congress on the Theory and Mathematics in Biology and Medicine,. Amsterdam Analysis of a discrete metapopulation model, Math. Biosci.,. Metapopulation theory was first developed for terrestrial ecosystems, and subsequently applied to the marine realm. In fisheries science, the term "sub-population" is equivalent to the metapopulation science term "local population". 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.

Many existing empirical studies use an incidence function approach based on spatial patterns and key assumptions about extinction and colonization rates.

Metapopulation theory is used to analyse the effects of habitat fragmentation on birds in the temperate zone, integrating various explanations for the paucity of species in isolated ecotopes. There is some evidence that turnover of local populations occurs in fragmented systems. Metapopulation theory suggests that additional patchiness may be caused by the dynamics of local extinctions and recolonisations.

1 Apr 2012 Classical metapopulation theory (CMT) has proven an attractive paradigm for ecologists concerned with the conservation of aquatic-breeding Metapopulation theory developed in terrestrial ecology provides applicable frameworks for interpreting the role of local and regional processes in shaping Metapopulation theory identifies biogeographical patterns among core and satellite marine bacteria scaling from tens to thousands of kilometers. Metapopulation theory has become a common framework in conservation biology and it is sometimes suggested that a metapopulation approach should be av V Johansson · 2012 · Citerat av 1 — In spatially realistic metapopulation theory, the colonization rate of a patch is determined by its distance to potential dispersal sources, i.e. to surrounding occupied patches (connectivity henceforth; Hanski, 1999), as an effect of restricted dispersal.
