Bioenergetics of Euphausia superba and Euphausia crystallorophias in the Ross Sea
Krill species are key organisms in the Antarctic food web. Biochemical composition in terms of lipids, proteins, carbohydrates, and fatty acids and its implications for spatial distribution were investigated in specimens of Euphausia superba and ...

Emerging Pollutants in Chinstrap Penguins and Krill from Deception Island (South Shetland Islands, Antarctica) [PDF]
This study aimed to evaluate the presence of emerging pollutants [perfluorinated compounds, phthalates and bisphenol A (BPA)] in chinstrap penguins (Pygoscelis antarctica) and krill (Euphausia superba) from Deception Island (South Shetland Islands ...

The complete mitochondrial genome of the ice krill Euphausia crystallorophias Holt & Tattersall, 1906 (Euphausiacea, Euphausiidae), from the Ross Sea, Antarctica [PDF]
The mitogenome of Euphausia crystallorophias collected from the Ross Sea Region Marine Protected Area (RSR MPA) is described for the first time. The assembled mitogenome was 17,291 bp in length and consisted of two ribosomal RNAs (rRNAs), 22 transfer ...

A circadian clock drives behavioral activity in Antarctic krill (Euphausia superba) and provides a potential mechanism for seasonal timing [PDF]
Antarctic krill is a species with fundamental importance for the Southern Ocean ecosystem. Their large biomass and synchronized movements, like diel vertical migration (DVM), significantly impact ecosystem structure and the biological carbon pump ...

Effects of some antiseptics on rate of Antarctic krill autoproteolysis [PDF]
Intensity of autoproteolysis in Antarctic krill (Euphausia superba) in the presence of some antiseptics was studied. The rate of autoproteolysis was assessed from release of amino and non-protein nitrogen in 100 g raw protein.
