Water potential at 50% loss of branch hydraulic conductivity (Ψ50; MPa) for the 25 canopy-tree species sampled in French Guiana. Each bar represents species mean (black, n ≥ 3; gray n < 3) with the number of replicates per species indicated in parentheses. Error bars represent standard errors of the mean. Insert: box plots of mean Ψ50 values for 329 adult tree species from different biomes (MED: Mediterranean forests/Woodlands, n = 77; TF: Temperate Forest, n = 133; TSF: Tropical Seasonal Forest, n = 54; TRF: Tropical Rainforest, n = 65) extracted from the meta-analysis by Choat et al. (2012) and with data for the 25 species in this study. Boxes show the mean (black dots), median (horizontal bar), 25th and 75th percentiles; error bars show the 10th and 90th percentiles
