1. Competition - colonization models
A metapopulaion model for two species can be given by the system of nonlinear differential equations
dp1
dp2
dt= c1p1(1 p1) m1p1
dt= c2p2(1 p1 p2) m2p2 c1p1p2
where pi is the fraction of patches occupied by species i, and ci and mi are the species specific rates
of colonization and extinction of patches, respectively. These equations assume that any patch has at
most one species, and species 2 patches can be taken over by species 1, but not vice versa.
(a) Suppose that m1= m2=3, c1=5, and c2=30. Find all equilibria.
