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 ...

Marine 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 ...

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.

Brazilian 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,

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 ...

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

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.
