The food and feeding ecology of the white-chinned petrel Procellaria aequinoctialis at South Georgia
Abstract: The diet of the white-chinned petrel at Bird Island, South Georgia was studied during ... the chick-rearing period in 1986 by quantitative analysis (by weight, frequency of occurrence and ... number of individuals) of regurgitated or lavaged adult stomach contents.

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 ...
