PERSISTENCE IN PLANKTON MODELS
WITH DELAYED NUTRIENT RECYCLING
SHIGUI RUAN AND GAIL S.K. WOLKOWICZ

Abstract. A plankton-nutrient interaction model with delayed nutrient recycling is considered. The system consists of three components, autotrophic phytoplankton, herbivorous zooplankton and dissolved limiting nutrient. Distributed delays are used to describe the contribution of phytoplankton and zooplankton that died in the past to the nutrient recycled at the present time. Persistence criteria are derived for the model by using Liapunov-like functionals.
