Coupling Genetic and Demographic Data to Reveal Dispersal Processes in Emperor Penguins

Ecology and Evolution, Volume 15, Issue 5, May 2025.
Dispersal is ubiquitous but dispersal rates, range, and behaviors remain difficult to measure. By developing new models combing demographic and genetic data, we propose to unravel species dispersal behaviors and apply our methodology to the emperor penguins, living in the most remote place on earth where measurements of dispersal are nonexistent.

Bovine Collagen Peptide Improves Hypoxia Tolerance and Anti‐Fatigue Capacity in Hypobaric Hypoxic Environments: A Combined Animal and Human Study

Food Science &Nutrition, Volume 13, Issue 5, May 2025.
This study represents the first demonstration that BCP can significantly enhance hypoxia tolerance and anti‐fatigue capacity under hypobaric hypoxia conditions, as confirmed by both animal and human experiments. ABSTRACT Peptides are recognized in functional foods for their biological activities.

Deep‐sea food‐web structure at South Sandwich Islands (Southern Ocean): net primary production as a main driver for interannual changes

Ecography, Volume 2025, Issue 5, May 2025.
Food‐webs are a major component of ecosystems and determinant for their functioning and structure. The food chain length (FCL) is a key feature of food‐webs and it is crucial for the resistance of the community to external stressors. The Southern Ocean (SO) food‐web is known for being short and dominated by an Antarctic krill Euphausia superba surplus,

The End of an Era? Trends in Abundance and Reproduction of Australian Southern Right Whales (Eubalaena australis) Suggest Failure to Re‐Establish Pre‐Whaling Population Size

Global Change Biology, Volume 31, Issue 5, May 2025.
Whaling in the 1800s and 1900s led to the near extirpation of Southern right whales. Despite a substantial increase in numbers since the 1970s, new research reveals that the recovery of Australian southern right whales is stalling, as previously birth rates have stopped growing and coastal abundances recently plummeted.

Evaluation of Antarctic krill (Euphausia superba) meal supplementation in diets for olive flounder (Paralichthys olivaceus)

, 2020
The supplemental effect of Antarctic krill meal (KM) into a low fish meal (FM) diet was evaluated for olive flounder (Paralichthys olivaceus). A 56% FM‐based diet was regarded as a high FM inclusion diet (HFM), and a low‐FM diet (LFM) was prepared by ...

Ice Algae-Produced Carbon Is Critical for Overwintering of Antarctic Krill Euphausia superba

Frontiers in Marine Science, 2017
Antarctic krill Euphausia superba (“krill”) constitute a fundamental food source for Antarctic seabirds and mammals, and a globally important fisheries resource.

Comparing trophic position estimates using bulk and compound specific stable isotope analyses: applying new approaches to mackerel icefish Champsocephalus gunnari [PDF]

PeerJ
Quantifying the tropic position (TP) of an animal species is key to understanding its ecosystem function. While both bulk and compound-specific analyses of stable isotopes are widely used for this purpose, few studies have assessed the consistency ...
