We examine the effect of stirring and mixing on the marine planktonic ecosystem. We present a number of models investigating the impact of patchiness in the population, diffusion, and fluid stirring on the spatial structure of the population and the overall production rates of the system. It is found that the heterogeneity of the system significantly affects the way the system behaves. The resp...

exploratory bouts in a novel environment? The only way to find out will be to record chronically across multiple units and cortical layers during the actual behavior and plasticity process. Finally, how such a shift in excitatory–inhibitory balance might be achieved is of interest. The brevity of the exploratory behavior required for bidirectional map changes is suggestive. Remarkably, just 4 m...
