Fig. 5 Observed and predicted relative abundance for nine target species. The dashed line represents a default prediction of plant growth which was calculated as 1/species richness. Observed and modeled data (solid lines) located above the dashed line indicates that a species was more productive in communities than would be predicted (i.e., overyield). Observed data from a current experiment (2016-2017) and a pre-existing experiment (2003-2004, Roscher et al. 2004) shown in black and grey, respectively. Null and PSF model predictions shown in green and blue, respectively. Statistical analyses in Supplementary Table 4.
