Table 1.

Mean, median, mode and quantiles for demographic parameters and mutation rate under scenario 1. These results were obtained with DiyABC version 2.0 (Cornuet et al. submitted). Q_2.5% and Q_97.5% are the 2.5% and 97.5% quantile values, respectively. All values were estimated from 500 000 and 5000 simulated data for priors and posteriors, respectively. Modes were not given for N_e1, N_e2, N_e3, N₁, N₂ and mu because their prior distributions were uniform.

N_e1, N_e2 and N_e3 = population effective sizes (number of individuals) for South African, NSW and Hawaiian populations, respectively; N₁ and N₂ = number of founders for the first and second colonization events (in NSW and then Hawaii); db₁ and db₂ = duration of the initial bottleneck after introduction in NSW and Hawaii (number of generations), respectively; K₁ and K₂ = intensity of the bottleneck in NSW and Hawaii, respectively; T₁ and T₂ = introduction times for the two colonization events (number of generations); mu = SSR mutation rate per locus and by geneation.
