metapopulation dynamics (Hanski 1991), we may ignore local dynamics and focus entirely on the presence or absence of species X in the habitat patches. In view of the practical applications of the model, let us further assume that changes in patch occupancy are scored at discrete time intervals, for

The spatiotemporal patterns of local extinctions and patch recolonizations create a shifting distribution of populations among patches. Metapopulation Dynamics: Empirical and Theoretical Investigations covers the 1989 proceedings of a metapopulation dynamics workshop held at Lammi Biological Station, Helsinki, Finland. It is divided into 18 chapters that cover various approaches to spatially structured population and community dynamics. These results demonstrate the importance of metapopulation dynamics and landscape connectivity for the persistence of populations in fragmented landscapes. The experimental fragmentation of In the context of metapopulation dynamics, generalists are expected to have higher landscape-scale occupancy than specialists, which leads to higher connectivity and higher colonization In accordance with metapopulation theory, our model describes how colonization and extinction processes determine spatial and temporal variation in occupancy dynamics (Hanski and Gaggiotti 2004).

Andrewartha, H. G. & Acknowledgements. I thank S. 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.

2004 ) using snapshot data on a set of epiphytic lichens. Levins' metapopulation model was the first model of population dynamics for the study of population processes in a heterogeneous environment (Fahrig, 2007; Levins, 1969). A toxicant‐dosed metapopulation model was used to explore the range of possible dynamics of populations in contaminated field sites. A single species metapopulation model was developed that is discrete, deterministic, and incorporates doseresponse curves and biotic growth rates to describe the effects of contamination on a metapopulation. 2005-03-08
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.

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 ideas play an increasingly important role in landscape ecology and conservation biology.

Skilled in Statistical Modeling, Biodiversity Modeling, Theoretical Ecology and Forestry Scenarios on Metapopulation Dynamics of Wood-Decaying Fungi.
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.
