There may be quite different levels of dispersal between the constituent populations of a metapopulation. For example, a large or overcrowded population patch is unlikely to be able to support much immigration from neighboring populations; it can, however, act as a source of dispersing individuals that will move away to join other populations

Keywords: metapopulations, models, host, … 2012-05-15 Se hela listan på study.com Metapopulation models have been used to explain life-history evolution, such as the ecological stability of amphibian metamorphosis in small vernal ponds. Alternative ecological strategies have evolved. For example, some salamanders forgo metamorphosis and sexually mature as aquatic neotenes. For example, populations of the checkerspot butterfly (Euphydryas editha) in California have a metapopulation structure consisting of a number of small satellite populations that surround a large source population on which they rely for new recruits. Metapopulation is a population in which individuals are spatially distributed in a habitat in two or more subpopulations. Populations of butterflies and coral-reef fishes are good examples of metapopulation . Human activities and natural disasters are the main causes of metapopulation and increase the population that occurs as metapopulatons.

2015, Schindler et al. 2015). 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.

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 propagule rain, is independent of the number of patches vacant or filled.

The model is fitted to data from three butterfly metapopulations. The model predicts well the observed For example, in a volume devoted to metapopulation dynamics (Gilpin. & Hanksi 1991), not a single paper dealt with the population biology of plants, and in two Jan 15, 2019 In fisheries science, the term "sub-population" is equivalent to the metapopulation science term "local population". Most marine examples are A metapopulation is a widely used concept in Ecology and Evolution. It is responsible for the stability Examples on Metapopulation… 7. Aquatic organisms in Mar 13, 2021 The Levins model has a special significance for metapopulation hence the Levins model is an example of patch occupancy metapopulations We used mangrove endemic bird metapopulations as examples of how conservationists may evaluate a changing landscape's capacity to support species. The classical metapopulation model predicts that metapopulations persist as long as there is a balance between extinction and colonization, with an equilibrium Figure 3.5 An example of high host suppression in a metapopulation model .

Woodlands provide a ﬁ rst example of urban habitat. Structural diversity in urban forest ecosystems, such as snags, decaying logs, leaf litter, and groundcover, provide habitat for many organisms.
