Demographic noise as a triggering mechanism for algal blooms    [PDF]

Piero Olla

Population models, such as those for plankton dynamics, are often based on a mean-field approximation of individual behaviors. A weakly stable mean-field configuration, however, can be destabilized by demographic noise. In certain cases, such destabilization persists even in the thermodynamic limit. The possibile relevance of such an effect to the onset of algal blooms is discussed.
