Table 6 Xylem hydraulic safety margins (HSM, MPa) derived from leaf and branch hydraulic traits 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
