The death rate for calves is calculated from data on calf survival rates Q as (1-Q).
We fit the data (see [1]) by adjusting the calf survival rate Q downward in the early
years for the given estimates. This is done in Fig. 31.6.
We are now ready to put the pieces of our model together to assess changes in the
wildebeest population given the influences of lions and rangers. Specifically, the
remaining population cohort model for wildebeest is shown in Fig. 31.7.
