Statistical analyses
A Kruskal‐Wallis test was used to
compare the values of each leaf
trait (laminaLMA, trichomeLMA, lamina thickness, trichome thickness,
leaf area, characteristic leaf dimension) among the elevational sites. A
single regression analysis was used to analyze the association between
trichome thickness and the temperature difference between intact and
trichome‐shaved leaves at the 1800 m site.
For the statistical and model
simulation analyses, we used the R statistical package (v.3.5.0; R
Foundation for Statistical Computing, Vienna, Austria).
