Solution to the ODE model (straight lines) and one sample path of the CTMC model (highly variable curves) for the reservoir species in its preferred habitat ($I_r$ and $P_r$) and in the overlap region ($I_a$ and $P_a$). The parameter values are given in Table 1 with $p_i=8$ and $p_o=52.$ Initial values are at the equilibrium values given in (4.2), rounded to the nearest integer.
