Stirring by swimming bodies

, 2010
We consider the stirring of an inviscid fluid caused by the locomotion of bodies through it. The swimmers are approximated by non-interacting cylinders or spheres moving steadily along straight lines. We find the displacement of fluid particles caused by

Protozoans as a food source for Antarctic krill, Euphausia superba: complementary insights from stomach content, fatty acids, and stable isotopes [PDF]

, 2006
We studied the diet of Antarctic krill, Euphausia superba, at five stations across the southwest Atlantic sector in summer 2003 by analyzing stomach content, fatty acids, and stable isotopes on the same individuals.

Active Transport of Carbon to Demersal Fish Communities in Shelf‐Slope‐Abyssal Systems of the North Atlantic Ocean

Global Biogeochemical Cycles, Volume 40, Issue 2, February 2026.
Abstract The biological carbon pump sequesters carbon through passive fluxes of biologically derived carbon, and by active vertical movement of marine organisms. Trophic coupling between pelagic and benthic communities increases the efficiency of the biological carbon pump as less carbon is lost to remineralization.

Resource potential and maturity estimates of Euphausia superba in East Antarctica

Frontiers in Marine Science
The East Antarctic krill fisheries are spread across two Divisions of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), Division 58.4.1 between 80-150°E and Division 58.4.2 between 30-80°E.

Krill Hotspot Formation and Phenology in the California Current Ecosystem

Geophysical Research Letters, 2020
In the California Current Ecosystem, krill represent a key link between primary production and higher trophic level species owing to their central position in the food web and tendency to form dense aggregations.

Facilitative interspecific interactions in marine vertebrates across scales: from individuals to ecosystems

Biological Reviews, Volume 101, Issue 1, Page 519-538, February 2026.
ABSTRACT Facilitative interspecific interactions (FIIs) confer benefits to at least one participant without detriment to others. Although often less emphasised than antagonistic interactions in ecological studies, this review highlights the significant ecological role of FIIs across biological scales – from individual behaviours to population ...

Penguin guano suppresses the grazing rate and modifies swimming behavior in Antarctic Krill (Euphausia superba)

Frontiers in Marine Science
Antarctic krill (Euphausia superba) are a key component of the Antarctic ecosystem linking primary and some secondary production to higher trophic levels including fish, penguins, seals, and whales.

Krill Oil Improves Mild Knee Joint Pain: A Randomized Control Trial.

PLoS ONE, 2016
BackgroundKrill oil is an edible oil extracted from krill, a small red-colored crustacean found in the Antarctic Ocean. The administration of krill oil is reported to mitigate inflammation in patients with cardiac disease, rheumatoid arthritis, or ...

Drivers of intrapopulation variation in resource use in a generalist predator, the macaroni penguin [PDF]

Intrapopulation variation in resource use occurs in many populations of generalist predators with important community and evolutionary implications. One of the hypothesised mechanisms for such widespread variation is ecological opportunity, i.e. resource

Natural growth rates in Antarctic krill (Euphausia superba): II. Predictive models based on food, temperature, body length, sex, and maturity stage [PDF]

, 2006
We used the instantaneous growth rate method to determine the effects of food, temperature, krill length, sex, and maturity stage on in situ summer growth of krill across the southwest Atlantic sector of the Southern Ocean.
