Figure 5

Effect of the resource supplying rate \(\pmb{\beta _{1}}\) on the bifurcation direction. In Figure 5, the parameters values are \(r_{1}=0.6\), \(r_{2}=0.3\), \(c_{1}=c_{2}=0.1\), \(\alpha_{21}=0.3\), \(a_{1}=0.1\), \(a_{2}=0.2\) and \(\varepsilon=0.1\). The left one shows supercritical bifurcation and the right one shows subcritical bifurcation.
