The First Genome Survey of the Antarctic Krill (Euphausia superba) Provides a Valuable Genetic Resource for Polar Biomedical Research

Marine Drugs, 2020
The world-famous Antarctic krill (Euphausia superba) plays a fundamental role in the Antarctic food chain. It resides in cold environments with the most abundant biomass to support the Antarctic ecology and fisheries.

Temperature and Ultraviolet Radiation Influence the Skin Microbiome of Humpback Whales

Molecular Ecology, Volume 35, Issue 15, August 2026.
ABSTRACT The skin microbiome of humpback whales harbours diverse microbial communities that play a crucial role in host skin protection and environmental interaction. However, studies on cetacean skin microbiomes in the Southern Hemisphere focus on feeding grounds, with limited information on microbiome dynamics at breeding grounds and during migration

Metabarcoding of Broad‐Diet Nototheniid Fish Stomachs Reveals Newly Detected Antarctic Parasite Signals and Potential Host Associations

Environmental DNA, Volume 8, Issue 4, July‐August 2026.
Using 18S rDNA metabarcoding of stomach contents from two Antarctic nototheniid fishes, we detected 242 parasite OTUs. Protists dominated diversity, metazoans dominated abundance, and depth structured assemblages. Novel parasite–host associations and previously unreported pathogenic protists highlight fish metabarcoding as a tool for biodiversity and ...

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

Food Safety and Health, Volume 4, Issue 3, Page 641-652, July 2026.
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 ...

Preparation and Hypoglycemic Activity of Enzymatically Hydrolyzed Peptides From the Swim Bladder of Pangasius bocourti

Food Science &Nutrition, Volume 14, Issue 7, July 2026.
Fish swim bladder is a low‐value byproduct from Pangasius bocourti processing. Herein, we successfully prepared hypoglycemic bioactive peptides from P. bocourti swim bladder (PBSBPs) via optimized alkaline protease hydrolysis. Peptidomic analysis revealed abundant low‐molecular‐weight peptides rich in hydrophobic amino acids with predicted α ...

Interactions between vertical migration and local oceanography drive microplastic exposure for Antarctic krill

Scientific Reports
Euphausiids play important roles in ecosystems worldwide, transferring energy from primary producers to secondary consumers. Antarctic krill are the most abundant euphausiid on Earth and play important roles as critically important species in Southern ...

Opportunistic feeding by Antarctic krill in the eastern Weddell Gyre

Limnology and Oceanography, Volume 71, Issue 7, July 2026.
Abstract Antarctic krill, Euphausia superba, is an important species in the Southern Ocean and is vulnerable to climate change. We studied the carbon sources for krill—specifically pelagic and ice‐associated (sympagic) particulate organic matter (POM), representing phytoplankton and sea‐ice algae, respectively—during March 2019 across three distinct ...

Oceanographic Drivers of Larval Transport Variability in South Atlantic Jasus paulensis Populations

Journal of Geophysical Research: Oceans, Volume 131, Issue 7, July 2026.
Abstract Effective fisheries management requires an understanding of the key influences on population variability. A fundamental driver of variability, particularly for isolated island populations, is the transport of planktonic early‐life stages.

Factors impacting the timing of reproductive development in female Antarctic krill at the northwestern Antarctic Peninsula

Frontiers in Marine Science
The northwestern Antarctic Peninsula is an important spawning, recruitment, and overwintering ground for Antarctic krill. The region is warming rapidly, and the current impacts of climate and environmental variability on the reproductive cycle of krill ...
