Description
Two coupled populations of species often exhibit complicated behavior in "coexistence", something noticable in both statistical physics simulations and in real biological contexts (parasite-host-interactions, prey-predator-interactions). In this talk I discuss the pertinent features: spatial patterns and temporal oscillations of populations in finite systems, and the relation between these two phenomena. One important aspect is how to characterize and detect the "patterns" and to be able to tell if a certain states has these or not. Another is to understand the joint oscillations of patterns, and the two populations. (work in collaboration with Matti Peltomaki, HUT, and Martin Rost, Bonn)
