Dynamics of a Two-Species Stage-Structured Competitive System with Time Delay and Optimal Harvesting

摘要：

In some two-species competitive models, only mature individuals participate in the competition,the immature individuals have little impact on the dynamics of the system. In this paper, we construct a two-species stage-structured competitive system with time delay-and optimal harvesting concerning the species competing between mature individuals. We obtain conditions for the existence of a globally asymptotically stable positive equilibrium and the maximum sustainable yield of harvesting for the mature population.
