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.
