Molecular Mechanism of Absorption, Transport and Metabolic Transformation of Astaxanthin in Aquatic Animals

open access: yesReviews in Aquaculture, Volume 18, Issue 4, September 2026.
This manuscript systematically elucidates the molecular mechanisms underlying absorption, transport, and metabolism of Astaxanthin in aquatic animals, through the analysis of biological functions, transport proteins, and enzyme metabolism system. Furthermore, it outlines future molecular research strategies for Astaxanthin, providing a theoretical ...

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

open access: yesMitochondrial 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 ...

Semi‐automated seal detection on the Western Antarctic Peninsula: an unsupervised machine learning approach for detecting ice seals in aerial survey data

open access: yesRemote Sensing in Ecology and Conservation, Volume 12, Issue 4, Page 645-660, August 2026.
This study presents a semi‐automated, rule‐based image analysis pipeline to detect ice seals in aerial surveys of the Western Antarctic Peninsula during an unusually low sea ice year. By using simple hierarchical clustering instead of deep learning, the method substantially reduced human annotation effort while achieving 82% recall, identifying 758 ...

The Effects of Microplastics and Additives on Ecosystem Function, Structure, and Signaling

open access: yesGlobal Change Biology, Volume 32, Issue 8, August 2026.
Microplastics disrupt ecosystem signaling through olfactory traps, altering predator–prey signaling and disrupting microbial communication and quorum sensing. ABSTRACT Microplastics (MPs) and their associated chemical additives are pervasive contaminants whose ecological impacts extend beyond organismal toxicity to fundamentally alter ecosystem ...

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

open access: yesFood 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 ...

Opportunistic feeding by Antarctic krill in the eastern Weddell Gyre

open access: yesLimnology 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 ...

Stable Isotope Analysis (δ13C and δ15N) of Baleen Plates Reveals Feeding Patterns in Stranded Humpback Whales (Megaptera novaeangliae) Along the Brazilian Coast

open access: yesMarine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Humpback whales (Megaptera novaeangliae) from breeding stock A migrate annually between Antarctic feeding grounds (~65° S) and Brazilian breeding areas (~17° S). Traditionally considered to fast during migration, recent feeding observations and increased strandings along southeastern Brazil (~23° S) raise questions about possible shifts in ...

Effect of body size, temperature and starvation on oxygen consumption of antarctic krill Euphausia superba

open access: yesBrazilian Journal of Oceanography, 1997
Routine oxygen consumption of krill was investigated as a general measure of its metabolism and assesses the effects of body size, temperature and starvation on the metabolism. No significant difference in whole animal consllmption was detected after 1,3,
