A REVIEW OF THE UNCERTAINTIES ASSOCIATED WITH PENGUIN POPULATION AND ABUNDANCE ESTIMATES FOR THE CCAMLR REGION
Abstract: This report reviews the availability of data describing penguin abundance in the CCAMLR ... Convention area, and the uncertainties in deriving overall abundance estimates from these counts. Counts of ... been collected using various demographic units, and the timing of these have varied relative to ... availability of these units.
