Geographic patterns of genetic diversity in Nothofagus cunninghamii as indicated by (a) estimated allelic richness (rarefied to smallest populations size) and (b) estimated private allelic richness (alleles found in a population that are absent from all other population measured per individual per locus). Subpopulations are indicated by dark dots on the map. Barriers to gene flow predicted with BARRIER are indicated by grey lines; the thickness of the edge of a barrier is proportional to the extent of the barrier and the adjacent numbers relate to the proportion of times the barrier was observed across 100 bootstrap replicates. Populations with high levels of private alleles are labelled.
