Fig. 3: Plant productivity and biodiversity effects by planted richness.
From: Dilution of specialist pathogens drives productivity benefits from diversity in plant mixtures
Average plant biomass (g m−2) (a), complementarity effect (b) and relative yield total (c) by plant richness in the 2nd season of the biodiversity manipulation experiment (2019). Monocultures and two species mixtures each contain 72 plots and three and six species mixtures 48 plots each. Boxplots indicate median (box center line), 25th (box bottom line), 75th (box top line) percentiles, and 5th (the lower whisker) and 95th (the upper whisker) percentiles. Different letters between boxes (b, c) indicate significant differences between combinations based on two-sided tests (α = 0.05, Kruskal–Wallis test, followed by a Dunn’s post hoc test). Asterisks in (b) and (c) indicate that complementarity and relative yield totals in richness levels 2–6 were significantly greater than 0 and 1, respectively. Source data are provided as a Source Data file.
