Figure 1From: Study on asymptotic behavior of stochastic Lotka–Volterra system in a polluted environment(a) (b) (c) denote persistent existence of the periodic solution of \(x(t)\), \(y(t)\), and \(z(t)\) respectively when there is weak environmental noise. The imaginary line denotes a solution of the stochastic system, the full line denotes a solution of the corresponding deterministic systemBack to article page
