1. Distribution and abundance of krill in the vicinity of Elephant Island in the 1992 austral summer

   Abstract:  Krill distribution and abundance were estimated from four acoustic surveys, conducted in the vicinity of Elephant Island, Antarctica, from mid-January to mid-March, 1992. The first and last surveys covered a 105 by 105 n.mi. study area centered on Elephant Island; the second and third

5. An automated weighing and recording system as an aid for the study of the foraging ecology of Adelie penguins (Pygoscelis adeliae)

   Abstract:  A System that automatically weighs, identifies and determines the direction of penguins moving between their breeding colony and the sea is described. Data obtained from it for a complete colony (589 nests from which 412 chicks were fledged) and related to the foraging ecology of the

6. An interpretation of the growth of the Adelie penguin rookery at Cape Royds, 1955-1990

   Abstract:  The population dynamics of the Cape Royds rookery were modelled by computer, in order to determine the probable causes of the dramatic increase since 1980 in the numbers of Adelie penguins, Pygoscelis adeliae, breeding in the Ross Sea region, Antarctica. Variations in the extent of sea

7. Recent increase and southern expansion of Adelie penguin populations in the Ross Sea, Antarctica, related to climatic warming

   Abstract:  The numbers of Adelie penguins Pygoscelis adeliae (Hombron and Jacquinot) in the Ross Sea, Antarctica, have increased markedly over the past 10 years. Proportionally, this increase is most pronounced in McMurdo Sound, where the species’ breeding range has recently been extended 3 km

8. Homogeneity of Adelie penguins as krill samplers

   Abstract:  A nest ANOVA design was used to measure the variance component due to differences between individual penguins in the length of krill eaten by Adélie penguins at Esperanza Bay. The value found was not different from zero: variance component =-0.16; F = 0.93; P = 0.54. This finding
