Sampling sites in the hybrid zone. Green shading corresponds to heavily forested regions considered to be a barrier to dispersal. Numbers correspond to site numbers listed in Table 2. The shading of the dots represent their cumulative Structure population assignment (including only individuals along the transect run at K = 2) averaged across all individuals in each population.
