Fig. 3From: Resource-dependent biodiversity and potential multi-trophic interactions determine belowground functional trait stabilityTypes of trophic association effects on soil functional trait stability across low and high resource available environments. Blue and red dots represent samples from low and high resource treatments, respectively. Solid and dashed lines represent the significant and non-significant linear relationships in low and high resource environments, respectively. WTA, within trophic association; CTA, cross-trophic association. *, P < 0.05; **, P < 0.01; ***, P < 0.001Back to article page
