Evolutionary dynamics of public good production. a At each time point the distribution of public good production in the lattice is plotted as a heat map. b-g Snapshots of the lattice at subsequent time steps (letters correspond between time plot and snapshots). Costs (per unit of public good) c=4.5, other parameters and colour coding in the snapshot as in Fig. 2. Lattice size =20482 (1/16 of the lattice is displayed for clarity). Time units are Monte Carlo steps. See also Additional file 1: Section 2 for the full snapshots, and movie at [29]
