Parameters are defined in Figure 5. Ne-ANC, Ne-N, Ne-P.tremula and Ne-P.davidiana indicate the effective population sizes of ancestral, P. tremula and P. davidiana population respectively, mP.tremula -> P.davidiana indicates the per generation migration rate from P. tremula to P. davidiana, mP.davidiana -> P.tremula indicates the per generation migration rate from P. davidiana to P. tremula, TDIV indicates the estimated divergence time between P. tremula and P. davidiana populations.
Parametric bootstrap estimates obtained by parameter estimation from 100 data sets simulated according to the overall maximum composite likelihood estimates shown in point estimation columns. Estimations were obtained from 100,000 simulations per likelihood.
