Environmental constraints on the lipid composition and metabolism of euphausiids:the case of Euphausia superba and Meganyctiphanes norvegica
Antarctic (Euphausia superba) and northern krill (Meganyctiphanes norvegica) are characterised by largescalespatial distributions. Euphausia superba is limited to the Southern Ocean, while M. norvegica is present from theArctic Ocean to the Mediterranean Sea. Euphausia superba structural lipids show...

Antarctic (Euphausia superba) and northern krill (Meganyctiphanes norvegica) are characterised by largescalespatial distributions. Euphausia superba is limited to the Southern Ocean, while M. norvegica is present from theArctic Ocean to the Mediterranean Sea. Euphausia superba structural lipids showed little mesoscale variability. Specificdifferences between phosphatidylcholine and phosphatidylethanolamine fatty acid composition exceeded variability relatedto sampling stations. On a larger scale (Southern Ocean), fatty acid composition of both total polar lipids andphosphatidylcholine confirmed the reduced level of regional variability. Similar comparisons between femaleM. norvegica collected at two extreme sites in terms of temperature regime (Kattegat and Ligurian Sea) during twoseasons (springsummer and fallwinter) suggested a more complex picture. Levels of phosphatidylethanolamine,lysophosphatidylcholine, and diphosphatidylglycerol showed significant differences between sites.
