<b>Dataset and R code for "</b><b>Plant functional trait dissimilarity drives plant mixture effects on fine root biomass and trait variations"</b>

We examined how functional dissimilarity—measured as functional dispersion in shade tolerance, drought tolerance, growth rate, and nitrogen-fixation ability—affects fine root biomass (RB), root length density (RLD), community-weighted rooting depth (WRD), and specific root length (SRL) by a global meta-analysis.
