Variations in climate conditions affect reproductive success of Antarctic krill, study finds
climate condition reproduction of krill SAM MEI seasonal variation
2021/8/4
Climate conditions play a significant role in the reproductive success of mature female Antarctic krill and are a factor in fluctuations of the population that occur every five to seven years, a new s...
Human-driven climate change only half the picture for krill
krill climate change natural variability ecological system
2021/8/4
New research about the fate of krill -- one of the most abundant species on Earth -- during this century has important implications for not only the Antarctic food web, but for the largest commercial ...
Krill hotspot fuels incredible biodiversity in Antarctic region
Krill hotspot fuels biodiversity Antarctic region
2017/7/24
There are so many Antarctic krill in the Southern Ocean that the combined mass of these tiny aquatic organisms is more than that of the world’s 7.5 billion human inhabitants.Scientists have long known...
Challenging the claim that intake of krill oil is associated with increased metabolic risk in overweight men
claim overweight men krill oil
2018/11/30
On 27 May 2015, the scientific study by Albert et al. (1) entitled “Supplementation with a blend of krill and salmon oil is associated with increased metabolic risk in overweight men” was published on...
A revised precautionary catch limit for Antarctic krill (Euphausia superba) in the Scotia Sea of 4 million tons was recently adopted by the Commission for the Conservation of Antarctic Marine Living R...
Feeding and overwintering of Antarctic krill across its major habitats: The role of sea ice cover, water depth, and phytoplankton abundance
Antarctic krill Feeding water depth
2014/4/2
Antarctic krill (Euphausia superba) were sampled in contrasting habitats: a seasonally ice-covered deep ocean
(Lazarev Sea), ice-free shelves at their northern range (South Georgia) and the Antarctic...
Seasonal and diel patterns in sedimentary flux of krill fecal pellets recorded by an echo sounder
echo sounder Seasonal diel patterns
2014/4/2
We used a moored upward-facing 200 kHz echo sounder to address sedimentation of fecal pellets (FPs) from
dielly migrating Meganyctiphanes norvegica. The echo sounder was located on the bottom at 150 ...
Seabed foraging by Antarctic krill: Implications for stock assessment, bentho-pelagic coupling, and the vertical transfer of iron
Seabed foraging by Antarctic krill Implications for stock assessment bentho-pelagic coupling the vertical transfer of iron
2014/4/8
A compilation of more than 30 studies shows that adult Antarctic krill (Euphausia superba) may frequent benthic habitats year-round, in shelf as well as oceanic waters and throughout their circumpolar...
Krill (Meganyctiphanes norvegica) swim faster at night
Meganyctiphanes norvegica temporal resolution
2014/4/8
Krill are key members in marine food webs, and measurement of swimming speed is vital to assess their
bioenergetic budgets, feeding, and encounters with predators. We document a consistent and marked...
ntarctic krill as a source of dissolved organic carbon to the Antarctic ecosystem
ntarctic kril dissolved organic carbon Antarctic ecosystem
2014/4/4
The role of krill as a source of dissolved organic matter in the Southern Ocean was tested through a series of
experiments performed around the Antarctic Peninsula. These experiments revealed high bu...

chromophoric dissolved organic matter bacteria krill the Southern Ocean
2014/4/17
Chromophoric dissolved organic matter (CDOM), the optically active fraction of dissolved organic matter, is primarily generated by pelagic organisms in the open ocean. In this study,we experimentally ...

Role of oxidative stress seasonal
2014/4/17
Vertical distribution and abundance of three numerically dominant krill species (Nyctiphanes simplex,
Nematoscelis difficilis, and Euphausia eximia) were surveyed in the Gulf of California to underst...

Physiology, growth, and development of larval krill Euphausia superba in autumn and winter in the Lazarev Sea, Antarctica
Physiology growth development
2014/4/17
The physiological condition of larval Antarctic krill was investigated during austral autumn 2004 and winter
2006 in the Lazarev Sea. The condition of larvae was quantified in both seasons by determi...
