Such a collection of populations and its dynamics is called metapopulation dynamics. Each local habitat in a metapopulation is referred as subpopulations. Levins Model: The concept of metapopulation was introduced by Richard Levins (an American ecologist) in 1969.

We give here the graph theoretic and dynamical systems context in which metapopulation models are formulated. 2.1 Introduction Metapopulation ecology remains one of the most dynamic and active areas of population ecology! Broadly speaking, a metapopulation is just a spatially structured population. 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 ! Metapopulation, in ecology, a regional group of connected populations of a species.For a given species, each metapopulation is continually being modified by increases (births and immigrations) and decreases (deaths and emigrations) of individuals, as well as by the emergence and dissolution of local populations contained within it. instead generates metapopulation dynamics in response to the empirically derived evolved individual-level life-history variation.

This paper describes a novel approach to modelling of metapopulation dynamics. The model is constructed as a generalized incidence function, which describes how the fraction of occupied habitat patches depends on patch areas and isolations. The model may be fitted to presence/absence data from a metapopulation at a dynamic equilibrium between extinctions and colonizations. Using the estimated

In addition, within a metapopulation, the creation or restoration of additional, discrete sites may buffer the whole population against the effects of localised events or demographic stochasticity (Hanski & Gyllenberg, 1993). Within a metapopulation, there may be both source populations and sink populations (Pulliam, 1988).

Metapopulation growth, in terms of the number of adults in the metapopulation (λ m) was mainly determined by local population processes, whereas change in patch occupancy (λ o) reflected the dispersal mode combined with seed 2020-11-07 · Metapopulation dynamics seem to be important for this species, since it may persist at a metapopulation level even though the conditions and population sizes in individual trees are changing. Partly, the colonisations and local extinctions could also be the result of source-sink dynamics. Metapopulation dynamics with quasi-local competition Theor Popul Biol.

Metapopulation dynamics. Metapopulation biology is concerned with the dynamic consequences of migration among local populations and the conditions of regional persistence of species with unstable local populations. Well established effects of habitat patch area and isolation on migration, colonization and population extinction have now become
