Figure 7. Relationship between the rate of transmission β and disease-induced death rates dH = dF in their effects on the Average Age of Recruitment to Foraging.
The figure shows the effects of an increase of β and dH on the AARF. Note that the AARF becomes less sensitive to changes in β as β is increased. Meanwhile, for small β, an increase in dH can have a favourable effect on the AARF.
