Elevational variations in stem hydraulic efficiency and safety of Abies fabri
The structural and functional traits of coniferous trees can reflect their growth states and adaptive strategies to a harsh environment.

and specific leaf area. Therefore, plants with better hydraulic and growth states at low elevations could allocate more resources to building up solid mechanical supporting systems to cope with high wind load, while those at high elevations with impaired growth states and limited hydraulic functions had to invest more resources in leaves under the harsh environment. The weak trade‐off between hydraulic efficiency and safety (lower hydraulic efficiency and high risk of embolism) could limit the growth and distribution of
A. fabri
at timberlines; however, global warming trends may facilitate hydraulic transport and benefit plants' growth in the future.
