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).
