Figure 5.

Effect of periodic treatment on inter-strain competition. The outcomes vary from long periods of 'y-domination' (top), to a coexistence pattern (middle) to persistent 'x-domination' (bottom). The upper plot has relatively short windows of 'x-domination', the lower one has persistent 'dominant x' by 1 or 2 orders of magnitude over y. The treatment cover is shown as gray areas; curve marking and axes are the same as Figure 4.
