Table 5 Key branch and leaf hydraulic traits. Water potential at 12 and 88% loss of branch hydraulic conductivity (Ψ₁₂, Ψ₈₈; MPa) and the slope of vulnerability curves (a_x; %MPa⁻¹) for the 25 canopy-tree species sampled in French Guiana. Results of a one-way ANOVA test for species effect for each studied trait are shown. Mean ± SE, F, and p values are displayed. Only species with at least three measured individuals are included in the analyses
