Fig. 7. Path analysis of selected traits. All path coefficients differ significantly from zero, except for maximum stomatal conductance and photosynthesis at wilting, which are marginal (P  = 0·057 and 0·059) and conductance at wilting, which is non-significant (P = 0·194). There is no significant misfit between the empirical data and the causal structure specified by the model (Satorra–Bentler robust χ² = 13·828, 17 d.f., P = 0·679, with Monte Carlo correction P = 0·774); comparative fit index (CFI) = 1·00, root mean square error of approximation (RMSEA) = 0·00, Akaike information criterion (AIC) = 540·76). The R² values are the percentage of variation explained by the causal variables. Values on the lines are the path coefficients between the causal variable and the caused variable. Solid lines are positive causal relationships and dashed lines are negative ones. Line thickness is proportional to the strength of path coefficients.
