Taxon richness: Estimated generalised additive model (GAM) terms showing the partial residuals (solid dots) and estimated smooth curve (solid line) of the number of all functional trait combinations (Total functional richness, panel A), response traits (Response richness, panel B), effect traits (Effect richness, panel C), and log₁₀ transformed community biomass (D).

<p>Shaded areas are ± confidence intervals above and below the estimated smooth curve. The estimated degrees of freedom of the plotted terms are in the Y-axis label. Zero values in the Y-axis indicate no effect of taxon richness on the smoothed dependent variable.
