It further provides the necessary scientific background on both metapopulation dynamics and population viability analysis.

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. Metapopulation Dynamics -Levins Model..
Levins Model: The concept of metapopulation was introduced by Richard Levins (an American ecologist) in 1969. Classical metapopulation dynamics In this section we seek to \scale up" from the two-patch model de-veloped in the preceding section to consider the dynamics of a pop-ulation on an arbitrary number of patches. Unfortunately, it is not feasible to simply add more equations to the existing system of two equations.

Some simple calculations show why. Metapopulation Dynamics Metapopulation theory and concepts are the central paradigm for understanding the spatial and temporal dynamics of species interactions. Our research explores these sorts of ecological dynamics using mathematical tools, species record databases and experimental approaches. 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. A metapopulation consists of a group of spatially separated populations of the same species which interact at some level.
