- Title
DYNAMICS OF AN AGE-STRUCTURED METAPOPULATION MODEL.

- Abstract
We introduce a metapopulation model that includes both landscape changes (patch destruction and recreation) and age-dependent metapopulation dynamics. A threshold quantity is derived and related to the existence of an ecologically nontrivial equilibrium, to the stability of the species- free equilibrium, and to weak and strong persistence of the species. We provide examples to illustrate how age-related changes in patch colonization and extinction rates can alter metapopulation persistence. Future field studies may need to address the temporal dynamics that characterize local populations in fragmented landscapes.
