Individual specialization and temporal changes in Antarctic fur seal trophic ecology from a multi‐tracer approach

Ecosphere, Volume 17, Issue 6, June 2026.
Abstract Substantial individual variation in diet and foraging strategies can exist within populations. These differences can enhance individual foraging efficiency, reduce intraspecific competition, and provide fitness advantages that increase the resilience of a population.

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.

DNA Metabarcoding Reveals Unexpected Predator–Prey–Microbial Dynamics in the Southern Right Whale (Eubalaena australis)

Molecular Ecology, Volume 35, Issue 12, June 2026.
ABSTRACT Southern right whale (Eubalaena australis; SRW) populations are recovering from the impacts of commercial whaling, however, recovery has been spatially variable, with strong associations between reproduction and prey availability. The diet of SRWs has not been widely examined, and with SRW foraging shifting away from high‐latitude foraging ...

Hemisphere‐Level Comparison of Climate‐Driven Humpback Whale Breeding Migrations to the Eastern Pacific Off Costa Rica

Ecology and Evolution, Volume 16, Issue 5, May 2026.
This study analyzed humpback whale occurrence off the Pacific coast of Costa Rica from 2001 to 2023, focusing on the Central America and Southeast Pacific Distinct Population Segments, using long‐term sightings and Bayesian time‐series and habitat models.

Biological characteristics of euphausiids preyed upon by Adelie penguin, Pygoscelis adeliae, breeding at Hukuro Cove, Lutzow-Holm bay in 1995/1996 [PDF]

, 2000
P(論文)Adelie penguins were used as a biological sampler from late December 1995 to late January 1996 to study biological characteristics of euphausiids in Lutzow-Holm Bay, which is generally covered with fast sea-ice even in summer.

Canyon effects structure fin whale feeding aggregations at Southern Ocean feeding grounds

Ecosphere, Volume 17, Issue 5, May 2026.
Abstract Large fin whale feeding aggregations at Southern Ocean feeding grounds are one of the most striking predator–prey phenomena in the post‐whaling era, representing a visible sign of recovering large whale populations. Yet, the mechanisms shaping their occurrence have not yet been studied. We investigate spatial patterns of fin whale distribution

Krill Oil Attenuates Acute Alcohol‐Induced Liver Injury by Remodeling Mitochondrial Dynamics and Metabolic Restoration

Food Frontiers, Volume 7, Issue 3, May 2026.
Krill oil attenuated acute alcohol‐induced liver injury by remodeling mitochondrial dynamics to rectify metabolic profiles. Specifically, KO restored the electron transport chain and enhanced AMPK/PPARα‐mediated fatty acid β‐oxidation, thereby resolving lipid accumulation and oxidative stress.
