  1. Parameters of the range expansion: K=1000, and m1=0.025; ρ of 5, 15 and 50 corresponds to m2 values of 0.005, 0.0016 and 0.0005, respectively. Expansion times: T=15 000 and T=1000.*: fragmentation intensity (see text for details). †: percentage of simulated datasets showing significant positive (%P) or negative (%N) values of D.
