DOI: 10.1007/s00227-021-03845-8
Abstract: Krill are abundant and ecologically important zooplankton that inhabit dynamic environments characterized by strong natural variability, but global ocean change is shifting the range of conditions that they experience. Laboratory tests reveal that krill are… read more here.

Astaxanthin stability and color change of krill during subcritical water treatment
Sign Up to like & getrecommendations! Published in 2017 at "Journal of Food Science and Technology"
DOI: 10.1007/s13197-017-2742-1
Abstract: Pacific krill (Euphausia pacifica) contains high amounts of astaxanthin, a carotenoid pigment with strong antioxidative activities. In this study, the effects of subcritical water temperatures (100–180 °C) and times (0–10 min) on color changes (L*, a*, and… read more here.

DOI: 10.1038/s41558-018-0370-z
Abstract: High-latitude ecosystems are among the fastest warming on the planet1. Polar species may be sensitive to warming and ice loss, but data are scarce and evidence is conflicting2–4. Here, we show that, within their main… read more here.

DOI: 10.1038/s41558-020-0745-9
Abstract: Crabeater seals exhibit extreme dietary specialization, feeding almost exclusively on Antarctic krill. This specialization has inextricably linked habitat use, life history and evolution of this pinniped species to the distribution of its prey. Therefore, the… read more here.
