The posterior probability of the parameters of the three colonization models for D. suzukii weighted by the posterior probability of each model, where N is the current population size, f is the number of founding individuals, τ is the colonization time for each population (in generations), and Nm is the migration rate among demes in the structured Japan population model. Note that the posterior distribution of τ_HI was plotted separately from the remaining τ estimates due to its unique prior range.
