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. 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.
