Extended Data Fig. 9: Effect of plant species richness on maintenance costs (d-1) of plants (a) and consumers (b).
From: Biodiversity increases multitrophic energy use efficiency, flow and storage in grasslands
(Supplementary Table 12). Maintenance costs were only calculated for living ecosystem compartments, thus not for the litter and soil organic matter. Thick lines: significant effects (P<0.05; analysis of variance with sequential sum of squares, type I, n=80); thin lines: non-significant effects (P≥0.05) of plant species richness, Supplementary Table 12. Shaded areas around lines show 95% confidence intervals. Filled dots: plots containing legumes; open dots: plots without legumes.
