WebWe introduce the idea of a network of dispersal, and see how metapopulation persistence depends on network structure. We draw a parallel with Susceptible-Infected-Susceptible models, in which individuals play the role of habitable patches and parasites disperse on a network of contacts. 8.1 Metapopulations WebVariations in movement have broad implications for many areas of ecology and evolution. For instance, in metapopulation theory, movement plays an important role promoting (meta)population persistence

WebA metapopulation describes a set of subpopulations linked by (rare) dispersal events in a dynamic equilibrium of extinctions and recolonizations. In the large body of literature that has accumulated, the term "metapopulation" is often used in a very broad sense; most of the time it simply implies spatial heterogeneity.
