Analysis of multivariate associations of leaf functional traits and the relationship between environmental factors and leaf functional traits. a redundancy analysis (RDA) presenting leaf functional traits (red lines) and environmental factors (blue lines); b principal component analyses (PCA) on leaf hydraulic traits (blue lines) and economic traits (red lines). TA: air temperature, AH: air relative humidity, SWC: volumetric soil water content, TS: soil temperature, Ψpd: predawn leaf water potential, Ψmd: midday leaf water potential, TLP: leaf turgor loss point, P50: leaf water potential at 50% loss of hydraulic conductance, Kleaf: leaf hydraulic conductivity. LDW: leaf dry weight, LT: leaf thickness, SLA: specific leaf area, SD: stomatal density, SL: stomatal length, Fv/Fm: maximum photochemical quantum yield of photosystem II. Dashed ellipses indicate 95% confidence interval
