Figure 4

Phase portrait for system (6). Purple and green lines show orbits converging to stable equilibria \((1,1)\) and \((0,0)\), respectively (black circles). Black arrows indicate the direction of convergence. The \(u_{A}\)- and \(u_{B}\)-nullclines are shown in blue and red, respectively. Yellow and orange lines show the separatrices of the degenerate saddle \((s_{1},s_{2})\) (red circle), where \(s_{1}=(b \tilde{s}_{A}-c+\theta )/a\) and \(s_{2}=(b \tilde{s}_{B}-c+\theta )/a\). More details are in the Supplementary Material 1.1
