Abstract The diet of the emperor penguin Aptenodytes forsteri in the western Ross Sea during spring was investigated by analysis of stomach contents sampled at three different localities. At Cape Washington, emperor penguins feeding chicks consistently preyed on fishes (89 to 95% by mass) and crustaceans (5 to 11%) over the four spring seasons examined. By far the commonest prey was the Antarctic silverfish Pleuragramma antarcticum (89% of the fish prey); the remainder of fish prey were mainly… Expand

Fish prey of Weddell seals, Leptonychotes weddellii, at Hope Bay, Antarctic Peninsula, during the late summer
TLDR
Given the high trophic vulnerability of this species to changes in abiotic factors and food web structure and dynamics, a possible influence of El Niño Southern Oscillation events of 2002–2003 and 2004–2005 should not be discarded. Expand
Diet of male southern elephant seals (Mirounga leonina L.) hauled out at Vincennes Bay, East Antarctica
Abstract. Male southern elephant seals (Mirounga leonina) are the largest of the pinnipeds and their foraging migrations take them from their breeding sites to Antarctica where some remain to moult.Expand
Diversified feeding strategies of Pleuragramma antarctica (Nototheniidae) in the Southern Ocean
TLDR
The trophic plasticity of the Antarctic silverfish, its ability to change and optimize the diet according to the prey availability, is explored to contribute to a throughout understanding of its response to environmental change. Expand
Gastrointestinal helminths of Emperor Penguin (Aptenodytes forsteri) from Antarctica
TLDR
The low parasite richness observed might be related to the stenophagic and pelagic diet of this host, and this is the first record of S. macronectes in the Emperor Penguin. Expand
Food preferences of larvae of Antarctic silverfish Pleuragramma antarcticum Boulenger, 1902 from Terre Adélie coastal waters during summer 2004
TLDR
Ichthyoplankton samples were collected from 19 to 31 January 2004 in the Dumont d’Urville Sea (East Antarctic shelf) and larvae were opportunistic feeders with a broad trophic niche, which allowed them to switch between different food types. Expand
Spatial and temporal diet variability of Adélie (Pygoscelis adeliae) and Emperor (Aptenodytes forsteri) Penguin: a multi tissue stable isotope analysis
TLDR
Investigation of the intra-annual diet of Adélie and Emperor Penguins belonging to five colonies in the Ross Sea through the stable isotope analysis of different tissues, synthetized in different seasons, and guano that indicates recent diet highlights a strong trophic plasticity in the AdÉlie Penguin. Expand
Isotopic niches of emperor and Adélie penguins in Adélie Land, Antarctica
TLDR
A comparison of isotopic niches revealed large overlaps in both blood δ13C and δ15N values within the community of Antarctic seabirds and pinnipeds, emphasizing the fact that all Antarctic seABirds and marine mammals feed on varying proportions of a few crustacean (euphausiids) and fish (Antarctic silverfish) species that dominate the intermediate trophic levels of the pelagic neritic and oceanic ecosystems.

Gastrointestinal parasite fauna of Emperor Penguins (Aptenodytes forsteri) at the Atka Bay, Antarctica
TLDR
Current data on parasites of the Emperor Penguin, a protected endemic species of the Antarctica, is provided to extend the knowledge on gastrointestinal parasites of Emperor Penguins at the Atka Bay, Antarctica. Expand
The trophic link between squid and the emperor penguin Aptenodytes forsteri at Pointe Géologie, Antarctica
Cephalopod beaks retrieved from stomachs of dead emperor penguin chicks at Pointe Géologie, Terre Adélie, provide information on taxonomic and size composition of the penguin’s squid diet, on theExpand

Squid diet of emperor penguins (Aptenodytes forsteri) in the eastern Weddell Sea, Antarctica during late summer
TLDR
The prey composition suggests that emperor penguins take squid at the steep slope regions of the eastern Weddell Sea. Expand

TLDR
The data suggest that Psychroteuthis glacialis probably hatch in July–September and grow steadily for one year, and then spawn and die. Expand
The foraging ecology of emperor penguins (Aptenodytesforsteri) at two Mawson coast colonies, Antarctica
TLDR
The results confirm the reliability of the tritium method as an estimator of food consumption by free-living emperor penguins (provided sea water and fresh water ingestion is known) and support the adoption of the 22Na method to derive an approximation of sea water intake by tritiated emperor penguin chicks and adult hunting performance during the period of chick care.

Seasonal and Geographical Variation in the Food of Weddell Seals, Leptonychotes-Weddelii, in Antarctica
TLDR
The food of Weddell seals was investigated between 1983 and 1985 at Davis, Mawson and McMurdo Sound, with seasonal changes in food types reflecting the movement of seals from shallow inshore waters during spring and summer to deeper offshore waters with the advance of the sea ice in winter. Expand

Diving Behavior and Energetics During Foraging Cycles in King Penguins
TLDR
It was concluded that deep—diving, for unknown reasons, is an important component of foraging success, and diving capacities of King Penguins are remarkable compared to other birds and many pinnipeds, and calculated foraging energetics can be closely estimated from time—energy budgets. Expand
