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.
For example, fire might sweep through the whole area occupied by the metapopulation, or climate fluctuations might have severe effects in all parts of the metapopulation, endangering the metapopulation as a whole. So far, the rates c and ε have been treated as though they are independent of p, the fraction occupied. This need not be the case.
Metapopulation is a population in which individuals are spatially distributed in a habitat to two or subpopulations. Populations of butterflies and coral-reef fishes are good examples of metapopulation . 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.

So far, the rates c and ε have been treated as though they are independent of p, the fraction occupied. This need not be the case. The entire set of populations in a region is called a metapopulation, or "population of populations." The component populations are often called subpopulations (see Concept 42.5 in the textbook).

This is a continuation of previous research on the amphibian metapopulations in the bay area of southern California, data will be analyzed in the laboratory and av AVG MICHANEK — The example shows how a planning basis can be produced. In order to metapopulation) använder, och som krävs för att populationen ska vara livs kraftig (i end of the twentieth century, is a striking example of mismanagement. Smedbol RK, and Wroblewski JS, (2002), Metapopulation theory and northern cod pockets of habitat where wildlife populations exist in isolation from other members of their species.
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

For example, the assumption that patches are all equally isolated could be made more realistic by specifying different migration rates among local populations. The types of modifications to the metapopulation model make the concept more useful (Ricklefs and Miller 2000).

example are r 1 = 1, r2 = 2, k 1 = 500, k2 = 300, and e = 1. In the special case of high dispersal (technically the e!¥ limit), the equilibrium sizes of the two populations are equal: n 2 1 = n 1 2 = n = r +r r1/k1+r2/k2.

The types of modifications to the metapopulation model make the concept more useful (Ricklefs and Miller 2000). Users alter the metapopulation structure by deleting the Patch Map spatial data, and replacing it with one of the Hexmaps stored in Patch Maps.
