Figure 2
Long-term demographic rates and biomass change for N-fixers (red) and non-fixers (blue box plots) across all plots. In the box plots, the thick line is the median, the edges of the box are 25% and 75% percentiles, the whiskers representing 1.5 times inter quartile range, and dots represent outliers. Asterisks indicate level of significance for tests of differences between N-fixers and non-fixers (*P < 0.05, **P < 0.01, ***P < 0.001).
