摘要

The role of viruses in marine phytoplankton-zooplankton community structure isundoubtedly very important. In this paper, we propose a simple mathematical model for phytoplankton-zooplankton (prey-predator) system with an additional factor that jthe viral disease is spreading only among the prey species. Considering high abundance and importance of viruses in aquatic environments we have explicitly considered here the growth equation of free viruses and have studied this four-dimensional model ana- lytically. It is observed that the disease-free system can be obtained when the virus replication factor lies in-between certain critical values. Numerical simulations have also been performed to [substantiate the analytical findings.
