Figure 7. stairwayplot (maximum likelihood Ne) (panel A) and normalized SFS (panel B) computed in simulated non-equilibrium SST scenarios with Tcol=15,000 generations B.P. and an instantaneous decrease of the migration rate (m) forward in time at Tch=10 generations B.P. Colours represent the long-term connectivity values: Nm=1 (blue), Nm=5 (green),Nm=10 (red), Nm=15 (black). Line style represents the 10-fold (small dashes) or 100-fold (dots) reduction of m, or constant Nm (continuous line). The vertical grey dashed line in panel A represents the simulated colonisation time Tcol.
