Abstract:
The motivation of the work presented here is to find what dispersal strategies are evolutionarily stable strategies (ESS) in an integrodifference equation framework, and look at how dispersal can evolve towards such an evolutionarily stable strategy. I will present integrodifference equation models that are temporally static or temporally periodic in which pairwise invasion analysis have shown that dispersal strategies associated with ideal free distributions are evolutionarily stable. I will also present some simulation results for a model with stochastic fluctuations.
