Abstract

We propose a two-species commensal symbiosis model with ratio-dependent functional response \[\frac{dx}{dt}=x\left(-a_1-b_1x+\frac{c_1y}{x+y}\right),\] \[\frac{dy}{dt}=y\left(a_2-b_2y\right),\] For autonomous case, we show that the unique positive equilibrium is globally stable if \(a_1 < c_1\) holds, and the boundary equilibrium \((0, \frac{a_2}{b_2})\) is globally stable if \(a_1 > c_1\) holds. For nonautonomous case, some sufficient conditions which ensure the permanence and global attractivity of the system are obtained. Numeric simulations are carried out to show the feasibility of the main results.
