Fig. 5.

(A and B) Two species competing for 2 nutrients, with supply $\overrightarrow{s}=\left(0.3,0.7\right)$ and ${\tau }_D=400$. Arrows indicate flow away from unstable fixed points. (A) Bistability for ${\alpha }_{11}=0.29$. (B) Allee effect for ${\alpha }_{11}=0.31$. Species 2 goes extinct if its initial population is too low. (C) The Allee effect in a competition with 10 species and 2 nutrients, with $\overrightarrow{s}=\left(0.4,0.6\right)$ and ${\tau }_D=100$. The blue and brown species displace each other, depending on initial conditions. (Inset) Strategies and supply.
