Figure 5

\(\mathcal{R}_{2}^{*}\) sensitivity diagram towards parameters p and \(h^{*}\), in the sense of continuous contour plot (a) and discrete contour plot (b). Figure (a) confirms sensitivity analysis in Table 3 that larger p and \(h^{*}\) will reduce \(\mathcal{R}_{2}\). The dashed red line in (b) is the critical line when \(\mathcal{R}_{2}^{*} = 1\) based on (16). The red area defines the coexistence condition, while the blue area defines an ecosystem with no hunters
