Consider the following linear model for deer that has a time step of one year and includes three stage classes: fawn, yearling,
and adult. F(1+1)) = .11 .15 25 F(t)
Y(1+1) = 0.5 0.1 0 Y (t)
A(1+1)) = 0 0.5 0.6 A(t)
a. What would it mean if the value in the upper right matrix element, 0.25, were increased to 2.0? Would the model still make biological sense?
b. The eigenvalues of this model modified as described in parteare: 1.122, 0.156+0.6221 and -0.156-0.6221. Has anything changed regarding the long-term survival of the deer population?
