Antarctic krill likely avoid underwater gliders

Deep Sea Research Part I: Oceanographic Research Papers, 2022
Abstract The extent to which marine species avoid survey vessels is the subject of considerable debate, with stimuli such as noise and pressure waves receiving particular attention. By some estimates, avoidance behaviour is a major bias in the assessment of pelagic species distribution and density. Surveyors of the marine environment are increasingly

Effect of Ultrasound-Assisted Thawing on the Quality of Euphausia superba and Its Changes during Cold Storage [PDF]

Shipin Kexue, 2023
In order to study the effect of ultrasound-assisted thawing on the quality of Antarctic krill (Euphausia superba) and its changes during cold storage, frozen Antarctic krill was placed into net bags or polyethylene (PE) bags and thawed by water immersion

Multidecadal warming of Antarctic waters [PDF]

, 2014
Decadal trends in the properties of seawater adjacent to Antarctica are poorly known, and the mechanisms responsible for such changes are uncertain. Antarctic ice sheet mass loss is largely driven by ice shelf basal melt, which is influenced by ocean-ice

The energetic cost of early reproductive development in juvenile Antarctic krill at the Western Antarctic Peninsula

Frontiers in Marine Science, 2022
The overwinter survival mechanisms of Antarctic krill, Euphausia superba, are poorly characterized, especially for juveniles. It has been suggested that juveniles adopt a mix of strategies characteristic of both larvae and adults.

Monitoring Antarctic krill (Euphausia superba) distribution in the Southern Ocean: environmental DNA (eDNA) adds to the toolbox

Frontiers in Marine Science
Antarctic krill (Euphausia superba Dana) is a key species of the Southern Ocean ecosystem, immensely abundant and targeted by the krill fishery. For their sustainable management, krill distribution and biomass estimates are required, typically achieved ...

Research Progress on Antarctic Krill Products and Their Quality and Safety [PDF]

Progress in Fishery Sciences
Antarctic krill (Euphausia superba) and its products have garnered increasing attention as valuable natural resources because of their rich nutritional profile, particularly that of their bioactive compounds such as proteins and phospholipids.

Di(2-ethylhexyl) adipate (DEHA) detection in Antarctic krill (Euphasia superba Dana)

Polar Research, 2018
In this reported study, a novel high-performance thin-layer chromatography (HPTLC) method was developed for the detection and quantification of the toxic substance di(2-ethylhexyl) adipate (DEHA) in Antarctic krill.

Oceanic circumpolar habitats of Antarctic krill [PDF]

Marine Ecology Progress Series, 2008
Surveys of Euphausia superba often target localised shelves and ice edges where their growth rates and predation losses are atypically high. Emphasis on these areas has led to the current view that krill require high food concentrations, with a distribution often linked to shelves.

Almond (Amygdalus communis L.) Peptides Improve Scopolamine‐Induced Learning and Memory Impairment in Mice

Food Safety and Health, EarlyView.
Figure Schematic showing the improvement of almond peptides on learning and memory impairment induced by scopolamine in mice. Almond peptides (APs) could improve the learning and memory in scopolamine‐induced mice by maintaining cholinergic system homeostasis and regulating Nrf2/Keap1 signaling pathway, via activating the Nrf2 transcription factor and ...

How does Drake Passage Oscillation Index (DPOI) effect on variability of the Antarctic krill ecosystem in the Antarctic Peninsula region? [PDF]

, 2016
Antarctic krill, Euphausia superba Dana, is a keystone species of the Antarctic ecosystem. Environmental and ecological change in Antarctica is one of key issues for the global climate change.
