Prediction of shoot growth in control community: Comparing the shoot weight of experimentally measured (red points, N = 8) and modeled (blue points, N = 900 covering potential variability in resource levels) data for each assessment date in control communities. Experimental values measured in fresh weight were converted to dry weight using a conversion factor based on a repeated monoculture control experiment, in which we measured the fresh to dry weight ratio of each species. Both broad spectrum herbicide and selective herbicide control values are included in the experimental data. Each experiment-model pair was tested for significance using a t-test; not significant results indicate that there are no differences between experimental and model data. Please note the logarithmic scale of the y-axis
