(C) Disease induced mortality rate <i>e</i>. (D) Dispersal rate <i>m</i> (log scale). Default parameters are given in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0086563#pone-0086563-t002" target="_blank">Table 2</a>, and one parameter is varied at a time. This is analogous to <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0086563#pone-0086563-g002" target="_blank">Fig. 2</a> for the non-spatial case. Initial conditions are such that 20% of sites are randomly chosen to start near the endemic equilibrium (with a minimum of 1 infective), while the remainder begin at the disease free equilibrium.
