dc.description.abstractSome plankton species like cyanobacteria have an advantage in the competition for light in comparison to other species because of their buoyancy. This advantage can be diminished by vertical mixing in the surrounding water column. We introduce a non-spatial model, based on ordinary differential equations, which accounts for this effect. The main aim is to show that vertical mixing influences the outcome of competition between different species. Hysteresis is possible for a certain range of parameters. Introducing a grazing predator, the system exhibits different dynamics depending on the strength of mixing. In a diffusively coupled horizontal spatial model, local vertical mixing can also have a global effect on the biological system, for instance, destabilization of a locally stable solution, or the generation of new spatiotemporal behavior.
