Prey (green) spread; predators (red) hunt them and starve without food. Spatial structure creates traveling waves the classic equations can't show.

\frac{d x}{d t} = 0.50 x - β x y, \frac{d y}{d t} = δ x y - 0.020 y

Reading this result: Predators have died out — with starvation at 0.02 they could not reach prey fast enough, so prey now fill the grid unchecked.
