Molecular phylogeny and mycorrhizal responsiveness for 95 grassland plant species from the Central Plains (Wilson & Hartnett, 1998). Taxa labels and bars shaded red indicate taxa classified as invasive. Effect sizes were based on log response ratios (ln[mean biomass of plants with AMF/mean biomass of plants without AMF]) of total plant biomass data. Positive log response ratios indicate plants were larger with arbuscular mycorrhizal fungi than controls. Wilson and Hartnett (1998) tested whether plants inoculated with AMF had significantly different biomass from controls by two‐sample t‐test (*p ≤ .05)
