Results of Structure 2.3.2 analysis (Pritchard et al. 2000) showing from K = 2 to the most likely K in (A) Nothofagus obliqua, (B) N. alpina, and (C) N. glauca. Clusters of populations are represented by colors. Populations are defined by vertical lines and ordered north to south within each species. Within individuals, the proportion of each color indicates membership to the given cluster. We employed Distruct 1.1 (Rosenberg 2004) to visualize and edit the Structure outputs.
