Figure 1.

Molecular phylogeny and mycorrhizal responsiveness measures for 68 grassland plant species from the Northern Plains. Taxa labels and bars shaded red indicate taxa classified as invasive. Effect sizes were based on total plant biomass (a) and shoot biomass (b). Positive standardized effect size measurements indicate plants were larger with arbuscular mycorrhizal fungi than sham‐inoculant controls. We tested whether plants inoculated with AMF had significantly different biomass from controls by two‐sample t‐test (*p ≤ .05)
