A Deterministic Size Structured Metapopulation Model

A metapopulation model is presented for species which can reach high population densities per patch, and for which migration is such a frequent event that it influences local patch dynamics. Depending on the local dynamics chosen and the way patch extinction is modelled, there can exist stable and bi-stable situations. The model is compared to winking-patch models, and single population models. Although, empty patches cannot exist in the model unless they are inhabitable, results comparable to those for the winkingpatch models do exist. Single population models appear to be of use to study the possible presence of a metapopulation.
