Relations between geographic distance and morphological (a) and neutral genetic (b) distance (IBD) among samples of Aquilegia canadensis from pairs of plots (20 plants per plot) within each of seven outcrops. Each point represents a pairwise comparison between plots. a Shows pairwise distances for floral morphology measured as the Euclidean distance between plot centroids for principal components of floral traits (r = +0.00101, Pperm~ 0.46). b Shows linearized pairwise genetic distance (linearized FST) for microsatellite polymorphisms (r = + 0.0297, Pperm ~ 0.37)
