a Two-population split where FP is treated as a single population. b Three-population split where FP is treated as two separate populations (FP1 = Tahiti, Mo’orea, Huahine and Raiatea; FP2 = Maupiti only). tintro = time of introduction to Tahiti; texp = time of population expansion following introduction; tcol = time of colonisation of Maupiti; tchange = time of switch to long-term population size of Maupiti population; NSNZ = current SNZ population size; NAll FP = current population size of French Polynesian population when treated as a single population; NFP1 = current population size of cluster 1 (Tahiti, Mo’orea, Raiatea and Huahine); NFP2 = current population size of cluster 2 (Maupiti); Nintro = population size following introduction; Ncol = population size following colonisation of Maupiti. Values in parentheses indicate parameter estimates from best model runs.
