PC1 and PC2 values for all collection records (N = 149). PC axes are inverted to mirror spatial orientation of populations in geographic space. Filled circles indicate the 9 focal populations used to assess trait variation. Across all collection records, species differ along PC1 (F(2, 82.2, P < 0.001) and PC2 (F(2, 59.76), P < 0.001). Post-hoc Tukey tests indicated that all 3 species differed from one another for both PC1 and PC2 (all P values < 0.001)
