Population Dynamics and Conservation of the - podarcis.de

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.

A practical model of metapopulation dynamics ILKKA HANSKI Department of Zoology, Division of Ecology, PO Box 17 (P Rautatiekatu 13), SF-00014, University of Helsinki, Finland Summary 1. This paper describes a novel approach to modelling of metapopulation dynamics. The model is constructed as a generalized incidence function, which describes how Metapopulation biology is concerned with the dynamic consequences of migration among local populations and the conditions of regional persistence of species with unstable local populations. Well established effects of habitat patch area and isolation on migration, colonization and population extinction have now become integrated with classic metapopulation dynamics.

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.
