Final individual plant biomass (mean ± 1 SD) for target species controls (15 plant monoculture – solid bars) compared with biomass under different relative densities of competitors (high, medium, low) for C. quitensis, D. antarctica and P. annua are shown in both a current scenario (A–C), and a wetting scenario (D–F). Different letters indicate significant differences.
