TABLE C1. Correlation coefficient among traits. Traits were not correlated among each other. We compared p values against α = 0.002 corrected by Holm-Bonferroni method, and detected no significant differences. Traits: RGR relative growth rate, PSR potential soil respiration, RD rooting depth, PP plant phenology, STA soil thermal amplitude, PSN potential soil nitrification, PSA potential soil ammonification, NRP nitrogen form relative preference.
