Source–sink dynamics has also been incorporated into studies of metapopulations, a group of populations residing in patches of habitat. Though some patches may go extinct, the regional persistence of the metapopulation depends on the ability of patches to be re-colonized.

Metapopulation dynamics

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.

I ﬁrst discuss the new perspective that metapopula- In fragmented landscapes, the evolutionary dynamics of adaptation may both decrease and enhance metapopulation viability in comparison with no evolution. The model can be applied to real patch networks with given sizes, qualities, and spatial positions of habitat patches. Spatiotemporal dynamics and distribution patterns of cyclic competition in metapopulation For a relationship of three-species competition similar to the game of rock–scissors–paper, which is an non-transitive competitive system in contrast to competitive hierarchies, we construct the Levins-like metapopulation model (LMM) Source-sink metapopulation dynamics WILD3810: Plant and animal populations In this lab, you will continue to learn about the dynamics of multiple interacting populations.

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

Metapopulation studies have important conceptual links with the equilibrium theory of island biogeography and with studies on the dynamics of species living in patchy environments.

Metapopulation dynamics.

Well established effects of habitat patch area and isolation on migration, colonization and population extinction have now become Metapopulation dynamics without dispersal. To explore metapopulation dynamics in the absence of dispersal, click on the "No dispersal" box underneath the four circles, and choose "Less" for "Distance" (the distance between subpopulations of the metapopulation).

To increase our understanding of metapopulation dynamics in static and dynamic landscapes, quantitative models are useful tools. They can be used to predict the response of species to a changing environment, or in conservation planning (Bascompte and Solé 1998, Hanski 1999, Akçakaya and Sjögren-Gulve 2000, Beissinger and McCullough 2002). metapopulation dynamics, habitat patch area and iso-lation, and to what extent other factors possibly im-prove the predictive power of metapopulation models.
