Starting from natural planktonic systems, we present a new mechanism involving spatial heterogeneity, and develop a new spatial structure model of planktonic predation systems. Firstly, the effect of diffusion on the dynamics of the system is investigated. We find that diffusion of only prey or both

We consider a predator᎐prey system with one or two delays and a unique positive equilibrium E#. Its dynamics are studied in terms of the local stability of E# and of the description of the Hopf bifurcation that is proven to exist as one of Ž . the delays taken as a parameter crosses some critical va
In this work, we study a predator-prey system with cross-diffusion, representing the tendency of prey to keep away from its predators, under the homogeneous Dirichlet boundary condition. Using fixed point index theory, we provide some sufficient conditions for the existence of positive steady-state
Direct observations on living animals, examination of gut contents, spatio-temporal distribution analysis, demographic data and a two year comparative study of zooplankton population dynamics illustrate the importance of invertebrate predation on the seasonal succession of the zooplankton in Lake Ay
