Dynamics of eco-evolutionary feedback in cooperator and cheater strains of the yeast <i>S. cerevisiae</i> , as observed in the experiment of Sanchez and Gore.
<p>There are two basins of attraction, with a different outcome expected from each. If there are too few cooperators to start, not enough simple sugars are produced and the population collapses. On the other hand, if the initial number of cooperators is sufficient, the system converges in spiraling fashion to an equilibrium in which cooperators and cheaters coexist.</p
