Different dynamical regimes for the mutualist-competitive system exist, depending on the values of the parameters.

<p>We define these regimes as follows: R1: Extinction. R2: Competitive exclusion, only species <i>X</i>₁ survives. R3: Competitive exclusion, only species <i>X</i>₂ survives. R4: bistability between extinction and coexistence. R5: bistability between survival of <i>X</i>₁ and coexistence. R6: bistability between survival of <i>X</i>₂ and coexistence. R7: coexistence of <i>X</i>₁ and <i>X</i>₂. (a) Influence of the growth rates <b><i>μ</i></b> in the chemostat system (b) Influence of the growth rates <b><i>μ</i></b> in the extended LV model (c) Influence of the flow rate Φ and the inflow in the chemostat for <b><i>μ</i></b> = [1600, 800]. (d) Influence of the flow rate Φ and the inflow in the extended LV model for <b><i>r</i></b> = [0.04, 0.02].
