Figure 2

Diagram of migration models used in simulations. The four panels represent in (a) an island model, (b) a hierarchical island model, (c) hierarchical stepping stone, and in (d) a stepping stone with 24 populations. Red disks represent random mating sub-populations (demes) and arrows the interconnecting migration routes (black arrows represent greater gene flow than grey ones). Dotted lines indicate archipelagos (b) or a contact zone (c).
