Figure 5. Sequential Equation Modeling for soil properties and AMF-colonization rates of Ruellia nudiflora . Solid and dashed lines indicate the positive and negative standardized paths, respectively. Path coefficients for RS (green arrows), OUS (blue arrows), and DUS (orange arrows) environments were reported together when detected significantly different by a multigroup test (see methods). Asterisks (*) denote path coefficients that are significantly different from 0. Different letters indicate significant differences between path coefficients. The SEM showed a good overall fit (χ22 = 2.661, P =0.264; CFI = 0.99; RMSEA = 0.074; SRMR = 0.053), as well as a good fit for RS (χ22 = 0.883, P =0.643; CFI = 1.0; RMSEA = 0; SRMR = 0.046), DUS (χ22 = 1.211, P = 0.546; CFI = 1.0; RMSEA = 0; SRMR = 0.046), and OUS (χ22 = 3.287, P =0.193; CFI = 0.00; RMSEA = 0.179; SRMR = 0.092).
