Deer population in the WMU 150 area for the full model. ((a) and (b)): If , then the disease persists, although it is stronger in males. ((c) and (d)): If , then the disease can be controlled and the population survives. In this case, only females are harvested, resulting in greater survival of males. ((e) and (f)): if , then the population is eradicated. In this case, only females are harvested, so their numbers decline quicker (solid curve; susceptible; diamonds: exposed; dashed curve: infected).
