Prior and posterior distributions of demographic and historic parameters used in ABC analyses.

Posterior distributions are estimated for the most likely scenario (i.e. scenario 1). The mean and median are given, along with 95% credibility intervals. All times (teuro, t1, t2, db and M) are in generations.
NGT: current effective size of Grande Terre.
NM0: current effective size of Maré.
NT: current effective size of Toupéti.
NM1: effective size of Maré during the post-colonisation bottleneck.
teuro: constrained colonisation time on Maré around 1900 in scenario 1, corresponding to 30 to 50 generations.
db: duration of the post-colonisation bottleneck.
t1: time before present of colonisation of Maré in scenario 2, 3 and 4.
t2: time before present of colonisation of Toupéti.
M: time of second colonisation on Maré in scenario 3 after the first one at t1.
r: admixture rate during the second colonisation event on Maré in scenario 3.
