Abstract:

A twodimensional nonautonomous system that arises in plankton allelopathy involving discrete time delays and periodic environmental factors is considered.  We obtain the conditions for the existence  of periodic solution of the system.

Key words: Plankton ecology, Allelopathy; , Time delay, Coincidence degree
