Data for: Phenotypic variation of hydraulic traits for woody species

Hydraulic traits are major determinants of plant fitness, thus exerting control over vegetation structure, function and distribution. Yet it remains unclear whether and how hydraulic traits respond to environmental stimuli (i.e., phenotypic variation of hydraulic traits; PVHT), and if the coordination between different hydraulic traits and the trait-climate relationship are affected by PVHT.
Here, we synthesized data of PVHT (maximum hydraulic conductivity and water potential inducing 50% loss of hydraulic conductivity) as well as potentially related morphological and anatomical traits (e.g. sapwood density, branch Huber value, mean and hydraulic weighted conduit diameter). We analyzed the magnitude, direction and source of variation of the plastic response, as well as the influence of environmental factors on trait coordination. Additionally, we compared the intra- and inter- specific variation between key hydraulic traits and climate metrics (mean annual precipitation and mean annual ..., , , # Phenotypic variation of hydraulic traits for woody species

The comparative dataset contains the responses of key hydraulic traits and related anatomical, morphological and physiological traits to different environmental stimuli. Plant traits incorporated in the dataset include water potential threshold triggering 12%, 50% and 88% loss of xylem hydraulic conductivity (P12, P50 and P88, respectively; -MPa), maximum hydraulic conductivity (K, kg m-2 s-1 MPa-1), leaf turgor loss point (tlp, -MPa), minimum water potential (WPmin, -MPa), predawn and midday leaf water potential (predawn and midday, respectively; -MPa), water potential threshold triggering stomatal closure (Pgs, -MPa), organ hydraulic capacitance (Cs, units can vary depending on method), specific leaf area (SLA, m2 kg-1), gs (maximum stomatal conductance, mol m-2 s-1), maximum leaf carbon assimilation rate (μmol m-2 s-1), sapwood density (WD,...
