In Fig. 5 we show the location of the Hopf bifurcation given by (12) as a function of the asymmetry between the two systems for ν = 0.05. Comparison with Figs. 3 and 4 shows the qualitative agreement of the theoretical results for the lower dimensional system with the full multistrain system. Increasing the migration rate ν increases the value of the bifurcation parameter to which the Hopf point saturates, as in Fig. 3 . It is also worth noticing that, in the case of identical frequencies ω 1 = ω 2 , the Hopf bifurcation occurs at α c = 0, the location in the absence of coupling. This is consistent with the numerical results for the multistrain system in the case of symmetric patches.
