a Kruskal‐Wallis test. ***: p < 0.001; **: p < 0.01; *: p < 0.05;: p < 0.10, n.s.: p ≥ 0.10.
b Characteristic dimension was calculated as the average length of the major and minor axes (leaf width) multiplied by 0.72 (Campbell & Norman, 2010).
c Vcmax andJmax were measured at different leaf temperature (TM ) for each elevational site. The values of the 100, 1280, and 2400 m sites partially included the data from Amada et al. (2017).
d In terms of the ecological significance of stomatal coefficient (a ), leaves with smaller a tend to keep lowergcs irrespective of environmental conditions, i.e., conservative stomatal behavior (isohydric leaves) while leaves with larger a can have higher gcs under optimum conditions, i.e., acquisitive stomatal behavior (anisohydric leaves) (see Appendix S3).
