Metapopulations in evolving landscapes

Phil Pollett

(Joint work with several people.)

Abstract: I will describe a model for populations that occupy several geographically separated patches of habitat, one which accounts for the evolution over time of landscape characteristics that affect the persistence of local populations. In particular, the probability of local extinction is allowed to evolve in time. This covers the widely studied case where patches are classified as being either suitable or unsuitable for occupancy. I will explain why, for large population networks, the persistence and equilibrium levels of the population are determined by the distribution of the life span of local populations, and not by the specific landscape dynamics.
