Patterns and processes in the distribution and dynamics of Antarctic krill
Abstract: A general framework is presented to develop, test and integrate component models of the ... 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 ...
