Table 3. Mean (±s.e.) of AM root colonization (%), fungal operational taxonomic units (OTU) richness and cumulative richness (mean Mao Tau±s.d., standardized to eight plants) within individual native grasses (four species), native forbs (five species), knapweed and spurge plants (Supplementary Table S6).

Plant community n AM colonization (%) OTU richness Cumulative richness
Native grasses 10 46.2 (4.33)c 7.80 (0.44)b 13.7 (0.38)
Native forbs 9 81.3 (1.99)ab 10.3 (0.67)a 21.3 (2.02)
Knapweed 8 76.1 (4.61)b 9.25 (1.08)ab 21.0 (1.66)
Spurge 10 90.7 (2.15)a 10.0 (0.70)a 21.2 (3.51)

Abbreviation: AM, arbuscular mycorrhizal.

Super-scripted letters indicate significant differences (P⩽0.05) among means using Fisher's lsd. Two knapweed plants and one native forb contained too few sequences to analyze.
