Dynamical study of infochemical influences on tropic interaction of diffusive plankton system

Abstract We propose a model for tropic interaction among the infochemical-producing phytoplankton and non-info chemical-producing microzooplankton. Volatile information-conveying chemicals (infochemicals) released by play an important role in food webs of marine ecosystems. Microzooplankton is ecologically grazer coexistence large number species. Here, we discuss how information transferred dimethyl sulfide shapes phytoplankton. Phytoplankton deterrents may lead to propagation IPP bloom. The between microzooplankton follows Beddington–DeAngelis-type functional response. Analytically, boundedness, stability Turing instability system. perform numerical simulation temporal (ODE model) as well spatial Our investigation shows that grazing refuse leads oscillatory dynamics. Increasing diffusion coefficient instability. Time evolution also plays system results obtained this paper are useful understand dominance algal bloom coastal estuarine ecosystem.
