Neighbour joining phenogram and Bayesian clustering analysis for 24 caves and 2 lake populations of Arctic charr. a Neighbour joining phenogram based on Cavalli-Sforza and Edward’s chord distance (Dce) showing relationships among cave populations (C) and lake populations (L). Only nodes with greater than 50% bootstrap support are shown. Double arrows indicate movements of tagged fish between two caves; pairwise Fst and Dest values were not significant in these cases (Appendix 2). b Bayesian clustering analysis using STRUCTURE for K = 5. The probability of assignment for each individual to each cluster is shown in a vertical bar. Labels correspond to the population identifier, the geographic area (V=Vindbelgur; H=Haganes) where the population is located and the subarea within that area (W = west; E = east; N = north; C = central; S = south). Each color corresponds to a distinct genetic cluster (Fig. 1)
