Trace element concentration in Antarctic krill reflecting their distribution in the Weddell Sea

Russian Journal of Earth Sciences, 2021
Distribution of Al, As, Cd, Co, Cu, Fe, Mn, Mo, Ni, Pb, Rb, and Zn in the main body parts and total samples of juvenile Antarctic krill Euphausia superba was examined in the northeastern Weddell Sea.

Pellet quality of krill meal and pea protein containing diets and their sinking velocity at different water temperature and salinity

Journal of the World Aquaculture Society, Volume 56, Issue 5, October 2025.
Abstract The present study investigated the effects of replacing low‐temperature fishmeal (LT FM) with graded levels of partly deshelled Antarctic krill (Euphausia superba) meal and pea protein concentrate (PDKM + PPC), PDKM alone, or whole krill meal with shells (WKM) as primary protein sources on feed pellet physical quality and sinking velocity (Sv)

Flexibility in Antarctic krill Euphausia superba decouples diet and recruitment from overwinter sea-ice conditions in the northern Antarctic Peninsula

, 2020
Winter sea-ice conditions are considered important for Antarctic krill Euphausia superba survival and recruitment, yet few broad-scale longitudinal studies have examined the underlying relationships between winter conditions and krill recruitment.

An Update on the Occurrence of Humpback Whale ( Megaptera novaeangliae ) Super‐Groups on the West Coast of South Africa

Marine Mammal Science, Volume 41, Issue 4, October 2025.
ABSTRACT Humpback whale ( Megaptera novaeangliae ) super‐groups, comprising 20+, tightly aggregated, feeding individuals, form during the austral summer in the southern Benguela ecosystem off the west coast of South Africa. This phenomenon, observed since 2011, is thought to be linked to increased productivity from positive chlorophyll‐a anomalies ...

Drone‐Based Photogrammetry Provides Estimates of the Energetic Cost of Migration for Humpback Whales Between Antarctica and Colombia

Marine Mammal Science, Volume 41, Issue 4, October 2025.
ABSTRACT Monitoring the body condition of animals offers insights into their energetic needs, prey consumption, and vulnerability to environmental pressures. Southern hemisphere humpback whales ( Megaptera novaeangliae ) depend on Antarctic krill for their annual energy requirements.

Membrane Lipid Remodeling Strategies Regulate Fluidity for Acute Temperature Adaptation in Oysters

Evolutionary Applications, Volume 18, Issue 9, September 2025.
ABSTRACT Extreme climatic temperature stress induced by global warming poses a severe threat to the survival of marine invertebrates. The plasma membrane functions as a natural barrier and serves as the first responder to ambient temperature through dynamic modulation of its fluidity.

Environmental Features Associated With At‐Sea Sightings of Snow Petrel Pagodroma nivea in East Antarctica

Ecology and Evolution, Volume 15, Issue 8, August 2025.
Over the last 70 years, seabird populations have declined by up to 70% across the globe. Compared to other seabirds, little is known about Snow Petrels and their marine habitat use—especially in East Antarctica. This study addresses the former knowledge gap while simultaneously comparing how outputs differ when data collection methods vary.

The complete mitochondrial genome of the ice krill Euphausia crystallorophias Holt & Tattersall, 1906 (Euphausiacea, Euphausiidae), from the Ross Sea, Antarctica

Mitochondrial DNA. Part B. Resources
The mitogenome of Euphausia crystallorophias collected from the Ross Sea Region Marine Protected Area (RSR MPA) is described for the first time. The assembled mitogenome was 17,291 bp in length and consisted of two ribosomal RNAs (rRNAs), 22 transfer ...
