Extended Data Fig. 1: Effect of herbivore exclusion and fertilization on plant diversity, richness and evenness.
Effect of herbivore exclusion (+H: herbivores present; −H: herbivores excluded) and fertilization (+F: fertilized with NPKμ; −F: unfertilized) on (a) plant diversity (b) richness and (c) evenness in sites with a long or short evolutionary history of grazing. Shown are sample points and bars representing means ± 1 SE (n = 76 for long-history sites and n = 103 for short-history sites per bar). Different letters indicate significant differences among the treatment means based on LMMs with herbivore exclusion and fertilization as fixed factors, and block nested within site as random effect.
