  • A steady migration of organisms out of the mainland to the islands, called propagule rain, is independent of the number of patches vacant or filled.

    The metapopulation is not the entire population, just the … The Mainland-Island Metapopulation

    • Several small “island” patches are within dispersal distance of a much larger “mainland” patch.
    • Though smaller patches have a high probability of local extinction, there is a highly improbable chance that the mainland population will ever become extinct.
    • A steady migration of organisms out of the mainland to the islands, called … 2017-08-16 For example, the assumption that patches are all equally isolated could be made more realistic by specifying different migration rates among local populations.

According to the Levins model, metapopulation persistence is due to a stochastic balance between local extinction and re-colonization of empty habitat patches.The rate of change in occupied habitat patches is a function of colonization rates (c) and extinction rates (e) as shown in Equation 5.2 (Levins 1969).

      Levin's metapopulation (classical metapopulation; narrow-sense metapopulation) En metapopulation är ett ekologiskt begrepp för system av lokala populationer av samma art som är rumsligt åtskilda. De lokala populationerna är så små att de löper en viss risk att dö ut, men de lokala utdöendena kompenseras av att nya lokala populationer uppstår genom kolonisationer.

      Modeling Dynamic Biological Systems - Bruce Hannon

      For example, an assumption of metapopulation theory is that dynamics of local populations are not synchronous (Freckleton & Watkinson 2002). Thus, even 1‐ or 2‐year studies of spatial variation in plant demography and/or effects of herbivores or pathogens on seed production provide useful inferences on the degree of spatial autocorrelation in plant fitness, and likely in population dynamics. Se hela listan på dictionary.sensagent.com Metapopulation models consider local populations as individuals. Dynamics of local populations is either not considered at all, or is considered in a very abbreviated way. Most of metapopulation models are based on colonization-extinction equilibrium.
