Results of model fitting and model choice of the demographic models tested in C. impatiens and C. resedifolia.

a Demographic model: CON = constant populations size; BOT = population size bottleneck; EXP = population size expansion; RED = population size reduction.b Marginal density.c Fraction of the retained simulations (n = 5,000, corresponding to 0.5% of the total simulations) with a likelihood smaller or equal to that obtained for the observed data (Model fit).d Posterior probability, estimated as ratio between the marginal density (MD) of a model and sum of the marginal densities across models.e Fraction of pseudo-observed datasets generated under the model (PODs) for which such model was correctly identified as the best based on posterior probability (pP). Random expectation is 1/(no. of models) = 0.25.f Posterior probability corrected using multivariate kernel density estimation with bandwidth = 0.1.Results of model fitting and model choice of the demographic models tested in C. impatiens and C. resedifolia.
