Variation in Antarctic Petrel Foraging Ecology: Not All Individuals Specialize on Krill

Frontiers in Marine Science, 2022
Individual heterogeneity in foraging behaviour determines how individuals and populations respond to changes in the availability and distribution of resources.

The application of optical coherence tomography to image subsurface tissue structure of Antarctic krill Euphausia superba [PDF]

, 2014
Many small open ocean animals, such as Antarctic krill, are an important part of marine ecosystems. To discover what will happen to animals such as krill in a changing ocean, experiments are run in aquaria where conditions can be controlled to simulate ...

Studies on food and fecundity of Notothenia gibberifrons Lönnberg, 1905 (Pisces, Notothenioidea) off South Georgia [PDF]

Acta Ichthyologica et Piscatoria, 1985
The food of sympatric, immature and mature (longer than 37.5 cm l.t.) individuals of Notothenia gibberifrons is very diversified, the most important items being the Polychaeta, Euphausia superba, the Isopoda, and the Echinodermata.

Vertical structure characterization of acoustically detected zooplankton aggregation: a case study from the Ross Sea

Frontiers in Marine Science, 2023
Acoustic data were collected by means of Simrad EK60 scientific echosounder on board the research vessel “Italica” in the Ross Sea during the 2016/2017 austral summer as part of the P-Rose and CELEBeR projects, within the framework of the Italian ...

Swarm of euphausiids in the ocean

Antarctic Record, 1981
Euphausiids often form dense swarm in the sea. The surface swarms of Euphausia superba, E. pacifica and some species of Thysanoessa are often observed in the polar waters. The size and density of swarms of euphausiids are various.

An Integrated, Size-Structured Stock Assessment of Antarctic Krill, Euphausia superba

Frontiers in Marine Science, 2021
The Antarctic krill (Euphausia superba) fishery is the largest fishery in the Southern Ocean, and it has been operating for over 45 years. In the past decade, the spatial distribution of the krill fishery has focused on the Bransfield Strait off the ...

Is It the Same Every Summer for the Euphausiids of the Ross Sea?

Diversity, 2022
The pelagic ecosystem in the Ross Sea has one central component that is very important for energy exchanges between upper and lower trophic levels: the Middle Trophic Level.

Regional Differences in the Diets of Adélie and Emperor Penguins in the Ross Sea, Antarctica

Animals, 2021
To identify the dietary composition and characteristics of both Adélie (Pygoscelis adeliae) and Emperor (Aptenodytes forsteri) penguins at four breeding sites, we performed stable carbon (δ13C) and nitrogen (δ15N) isotope analysis of down samples taken ...

Influence of individual state on swimming capacity and behaviour of Antarctic krill Euphausia superba [PDF]

, 2008
Swarms of Antarctic krill are frequently biased towards certain body sizes, sexes, maturities and physiological states. However, the mechanisms causing such biases remain unclear, with some speculating on differential responses to chemical or visual cues.
