Selective feeding in Southern Ocean key grazers—diet composition of krill and salps

Communications Biology, 2021
Over the past decades, two key grazers in the Southern Ocean (SO), krill and salps, have experienced drastic changes in their distribution and abundance, leading to increasing overlap of their habitats. Both species occupy different ecological niches and

North Atlantic warming over six decades drives decreases in krill abundance with no associated range shift

Communications Biology, 2021
In the North Atlantic, euphausiids (krill) form a major link between primary production and predators including commercially exploited fish. This basin is warming very rapidly, with species expected to shift northwards following their thermal tolerances.

Krill excretion boosts microbial activity in the Southern Ocean.

PLoS ONE, 2014
Antarctic krill are known to release large amounts of inorganic and organic nutrients to the water column. Here we test the role of krill excretion of dissolved products in stimulating heterotrophic bacteria on the basis of three experiments where ...

Krill Oil for Knee Osteoarthritis: A Randomized Clinical Trial.

Journal of the American Medical Association (JAMA)
Importance Knee osteoarthritis is disabling, with few effective treatments. Preliminary evidence suggested that krill oil supplementation improved knee pain, but effects on knee osteoarthritis remain unclear. Objective To evaluate efficacy of krill oil

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 ...
