Antarctic krill (Euphausia superba) are a circumpolar species with an omnivorous diet. Knowledge of krill diet within different regions will help predict how environmental change may impact local krill populations. Krill from the Atlantic, Indian…
Antarctic krill (Euphausia superba) are a key component of the Antarctic food web with considerable lipid reserves that are vital for their health and higher predator survival. Krill lipids are primarily derived from their diet of plankton, in particular diatoms and flagellates.
The Antarctic krill (Euphausia superbaDana, 1850) is an important trophic link between phytoplankton and higher trophic levels. Knowledge of the lipid biochemistry of krill assists in understanding their seasonal biology and predicting their responses to ecological changes.
Despite widespread iron (Fe) limitation in the Southern Ocean, intense phytoplankton blooms are observed around productive coastal regions such as the Mertz Polynya (off George V Land and Adelie Land, East Antarctica; 140–155°E). Sources of Fe across coastal East Antarctica vary…
Antarctic krill (hereafter krill) is the key species of the Antarctic marine ecosystem as well as a target of commercial fishery in the Southern Ocean, which compels careful predictions about potential impacts of Ocean Acidification (OA)…
This paper aims to provide the overview needed to include krill in food-web models and to guide modellers to key sources of data. It describes the strengths of each method of sampling krill, i.e. with nets (for historical time series, demographic information and live krill), acoustics (distribution…
In 2001 and 2003 small-scale acoustic surveys of Antarctic krill (Euphausia superba) distribution and abundance were conducted … offshore from an East Antarctic colony of Adelie penguins on Bechervaise Island (671350S, 621490E) that has been monitored for … 15 years.
