A metapopulation is a �population of populations� distributed in discrete habitat patches that are linked by occasional dispersal. Rather than track individual organisms through time, a metapopulation approach tracks the occupancy of habitat patches through time. Metapopulation ecology is a key concept in conservation ecology. Although pure metapopulations may be rare, there are many empirical studies in which metapopulation processes, primarily local Metapopulation Ecology Saskya van Nouhuys, University of Helsinki, Helsinki, Finland A metapopulation is a spatially structured population that persists over time as a set of local populations in balance between local extinction and colonization.

Thus, it cannot be automatically assumed that increasing matrix quality will lower the probability of global extinction of a population.

Although it has been argued that metapopulation persistence and extinction are affected strongly by the rate at which the landscape changes (Adler & Neurnberger 1994; Keymer et al. 2000; Childs et al. 2004), the degree to which changes in patch connectivity affect persistence still remain a challenge for theoretical spatial ecology.

Therefore, the species is more likely to occur in a large and well-connected patch compared to a small and isolated one. av J Hedin · 2003 · Citerat av 28 — Abstract: This thesis starts with a review of different biodiversity assessment methods in forests and the rest deals with the metapopulation ecology of  LIBRIS titelinformation: Metapopulation ecology of Osmoderma eremita : dispersal, habitat quality and habitat history / Jonas Hedin.

Now that we’re thinking about animals living in particular areas in space, we need to start thinking about movement ecology in addition to population ecology ! Publisher Summary. Landscape ecology is the study of the effect of spatial pattern on an ecological process. It thus follows that adopting a landscape ecological perspective to metapopulation dynamics entails understanding how a spatial pattern, such as habitat fragmentation or heterogeneity, affects the processes that contribute to the dynamics of spatially structured populations.
