Abstract:
 In this paper, we establish a global attractor for a Lotka-Volterra
 type reaction-diffusion predator-prey model with stage structure
 for the predator, delay due to maturity and variable coefficients.
 This attractor is found by the method of upper and lower solutions
 and is given in terms of bounds for the coefficients.
