1. Fish and squid in the diet of king penguin chicks, Aptenodytes patagonicus, during winter at sub-Antarctic Crozet Islands

   Abstract:  The diet of king penguins, Aptenodytes patagonicus, rearing chicks was studied during three consecutive austral winters (1990, 1991 and 1992) at Crozet Islands. The mean stomach content mass of the 47 samples was 503 g. Percentages of wet and reconstituted masses showed that both fishes

2. Diet and feeding ecology of the diving petrels Pelecanoides georgicus and P. urinatrix at South Georgia

   Abstract:  The diet of the diving petrels Pelecanoides georgicus and P. urinatrix was studied during 1986 (P. georgicus) and 1987 (both species) by lavaging adults as they returned to feed chicks on Bird Island, South Georgia. The diet of both species was dominated by crustaceans. in particular

3. Milk consumption and growth efficiency in Antarctic fur seal (Arctocephalus gazella) pups

   Abstract:  The body composition, milk consumption, and growth efficiency of Antarctic fur seal (Arctocephalus gazella) pups were measured over three consecutive lactation periods (1990-1992) at Bird Island, South Georgia. The body composition of pups differed between the sexes; whereas for any

4. Interannual variation in the diet of the Antarctic prion Pachyptila desolata at South Georgia

   Abstract:  The diet of the Antarctic Prion Pachyptila desolata was examined using food samples regurgitated by adult birds during five breeding seasons at Bird Island, South Georgia. In all years the diet was mainly crustaceans, with a small proportion of myctophid fish and trace amounts of

6. Milk fatty acid signatures indicate both major and minor shifts in foraging ecology of lactating Antarctic fur seals

   Abstract:  Fatty acid signature analysis is based on the conservation and unique signatures of fatty acids in the marine food chain and it may be useful in determining the composition of seal diets or in detecting changes in diets. We apply fatty acid signature analysis to milks collected from

7. Dietary segregation of krill-eating South Georgia seabirds

   Abstract:  The diets of six of the main seabird species (two petrels, two albatrosses, two penguins) breeding at Bird Island, South Georgia were studied simultaneously during the chick-rearing period in 1986. For five species, Antarctic krill Euphausia superba was the main food (39-98% by mass);

8. Development of the krill stock in the elephant island region during the 1996/97 season

   Abstract:  During December 1996 the Elephant Island standard grid was surveyed for krill and salps. Krill and salps were present at almost all of the stations, other epipelagic zooplankton species were relatively scarce. Maximum krill density exceeded 7350 juvenile krill per 1000 m3. In general

9. Consumption of krill by minke whales in Areas IV and V of the Antarctic

   Abstract:  The consumption of Antarctic krill (Euphausia superba) by the southern minke whale (Balaenoptera acutorostrata) in Areas IV and V of the Antarctic was estimated from diurnal change in the forestomach content mass, standard metabolism and the body mass increase methods based on JARPA (the

10. Interannual changes in body fat condition, stomach content mass and distribution of minke whales in Antarctic Areas IV and V

    Abstract:  As an indicator of body fat condition, interannual variability in girth of minke whales (Balaenoptera acutorostrata) was analyzed in relation to sea-ice extent, stomach-content mass and distribution of minke whales in Antarctic Areas IV (70°-130° E) and V (130° E-170°W) from 1989/90 to
