Table 4 Number of replicates for key branch and leaf hydraulic traits. Water potential at 50% loss of branch hydraulic conductivity (Ψ₅₀; MPa), midday leaf water potential during a normal intensity dry season (Ψ_md; MPa), leaf water potential at turgor loss point (π_tlp; MPa), xylem hydraulic safety margins (HSM; MPa), and leaf safety margin (SM_leaf; MPa) derived from leaf and branch hydraulic traits for the 30 canopy-tree species sampled in French Guiana. Results of a one-way ANOVA test for species effect for each studied trait are shown. Only species with at least three measured individuals are included in the analysis
