Patterns and processes in the distribution and dynamics of Antarctic krill
distribution and dynamics of Antarctic krill population at various spatial and temporal scales. We suggest that ... models of increasing complexity be developed iteratively for variability and patchiness of krill ... abundance. Incremental models should then be compared to statistical descriptions of the observed ... critical processes to be added.
