   FIG. D1. (A) Mean total biomass of Centaurea maculosa from European and North American populations, and with and without Agapeta zoegana infecting roots; mass was measured at the end of the experiment. ANOVA: region – F1,13 = 6.62, P < 0.0175; population – F11,69 = 2.19, P < 0.0372; Agapeta – F1,69 = 1.14, P = 0.722. (B) Mean total biomass of Centaurea maculosa from European and North American populations, at the end of the experiment with Cyphocleonus achates; controls and treatment combined. ANOVA: region – F1,11 = 10.11, P < 0.001; population – F11,69 = 1.24, P = 0.277.
