Resource matching and population dynamics in a two-patch system

We study resource matching the relationship between resource supply and for ager numbers under conditions of fluctuating population dynamics in a two-p atch system. For the inter-patch dispersal we apply the patch-departure rul e following the principle of the ideal Free distribution: leave the current patch of residence if local conditions are worse than conditions elsewhere on average. We show that such a dispersal rule synchronises cyclic and cha otic local population dynamics, but unlike many other dispersal rules, leav es the underlying population dynamics untouched. We also show that the IFD dispersal rule is not very sensitive to biased information and navigation f ailures during the dispersal phase. Even under such circumstances we observ e a quick process of populations becoming synchronised, even when the popul ation dynamics are chaotic. We conclude that an IFD patch-departure rule re presents an ESS dispersal behaviour towards which the dispersal patterns sh ould evolve.
