Diversification, evolution and sub-functionalization of 70kDa heat-shock proteins in two sister species of antarctic krill: differences in thermal habitats, responses and implications under climate change. [PDF]

PLoS ONE, 2015
A comparative thermal tolerance study was undertaken on two sister species of Euphausiids (Antarctic krills) Euphausia superba and Euphausia crystallorophias.

Refining Zooplankton Diet Composition Studies Over Short and Long Time Scales by Combining 18S Metabarcoding With Fatty Acid Analyses. [PDF]

Mol Ecol Resour
ABSTRACT Understanding diet composition is essential for unravelling trophic interactions in aquatic ecosystems. DNA metabarcoding, utilising various variable regions of the 18S rRNA gene, is increasingly employed to investigate zooplankton diet composition.

Effects of Tea Polyphenol and Its Combination with Other Antioxidants Added during the Extraction Process on Oxidative Stability of Antarctic Krill (Euphausia superba) Oil

Foods, 2022
Antarctic krill (Euphausia superba) oil contains high levels of marine omega-3 long-chain polyunsaturated fatty acids (n-3 LC-PUFA), including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).

Purification, Identification, Activity Evaluation, and Stability of Antioxidant Peptides from Alcalase Hydrolysate of Antarctic Krill (Euphausia superba) Proteins

Marine Drugs, 2021
For utilizing the largest source of marine proteins, Antarctic krill (Euphausia superba) proteins were defatted and hydrolyzed separately using pepsin, alcalase, papain, trypsin, and netrase, and alcalase hydrolysate (EPAH) showed the highest DPPH ...

Bioenergetics of Euphausia superba and Euphausia crystallorophias in the Ross Sea

Diversity, 2023
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 ...

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 ...

Effects of some antiseptics on rate of Antarctic krill autoproteolysis [PDF]

Acta Ichthyologica et Piscatoria, 1981
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.

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.
