Territorial spatial structure renders diversity robust to variation in enzyme budgets. (A) In a community with equal enzyme budgets and $\overrightarrow{s}=\left(0.4,0.6\right)$ (Left), 10 species coexist in the well-mixed model (Center), whereas only 3 coexist in the spatial model (Right). (B) In a community with the same strategies as A but unequal enzyme budgets (Left), 2 species coexist in the well-mixed model (Center), whereas 7 coexist in the spatial model (Right). (C) Probability of effective number of species $M$ at steady state for random enzyme budgets, in the well-mixed model with $\overrightarrow{s}=\left(0.4,0.6\right)$. For 2,000 sets of strategies, each of 20 initial species’ enzyme budgets $E_{\sigma }$ was drawn from $\mathcal{N}\left(1,\delta E\right)$. (D) Same as C but for spatial model.
