In old-growth forests of Douglas fir, the spotted owl dines mainly on flying squirrels. Suppose the predator-prey matrix for the two populations is A =
and assume that any initial vector x, has
-p 1.5
an eigenvector decomposition xp = C, V, +... + c, V, such that c, > 0. Show that if the predation parameter p is 0.375, both populations grow. Estimate the long-term growth rate and the eventual ratio of
owls to flying squirrels.
If p = 0.375, the eigenvalues of A are 1.25,0.45 . Both populations grow because
of these eigenvalues is/are greater than 1.
