Metapopulation theory, its use and misuse

Baguette (2004) has criticized the use of patch-occupancy metapopulation models in conservation. I discuss the relative strengths and weaknesses of different types of metapopulation models, taking for granted that there is a need to develop both general theory and predictive models. I conclude that the classical metapopulation theory is most appropriate for species living in highly fragmented landscapes. For these situations, the patch-occupancy metapopulation models provide a modelling approach that has been helpful also for conservation. (C) 2004 Elsevier GmbH. All rights reserved.
