Hierarchical structuring of molecular variation (AMOVA) within and among a priori defined populations and groups based on rDNA sequences only. Subset 1: 15 populations grouped into four groups; Subset 2: 8 populations from the SW Pacific grouped into two groups. Statistical significance is based on 10,100 permutations in Arlequin: * P < 0.05; ** P < 0.001.
