Physical barriers, sources–sinks, and population and metapopulation dynamics are thus not modeled explicitly , although models have been developed to integrate certain features of the relevant dynamics with SDMs (21, 35, 47, 48). 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.
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.

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 dynamics and reserve network design
The term metapopulation was coined by Richard Levins in 1969 to describe a model of population dynamics of insect pests in agricultural fields, but the idea has been most broadly applied to species in naturally or artificially fragmented habitats. 1997-01-01 · Metapopulation dynamics may contribute to the development of landscape ecology by emphasizing the dynamics that occur in a landscape. 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.
The observation that locally abundant species tend to be widespread, whereas locally rare species tend to be narrowly distributed, is one of the most pervasive patterns in ecology (1–3). Physical barriers, sources–sinks, and population and metapopulation dynamics are thus not modeled explicitly , although models have been developed to integrate certain features of the relevant dynamics with SDMs (21, 35, 47, 48).
