Divergent exploratory‐avoidant behavioural strategies may drive niche differentiation in juvenile Antarctic fishes

Journal of Fish Biology, EarlyView.
Abstract We used an ecological niche theory framework integrating physiological and behavioural ecology to understand interspecific differentiation of juveniles of four Antarctic fishes: Trematomus bernacchii, Trematomus pennellii, Trematomus nicolai and Pagothenia borchgrevinki.

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.

Flume Tank Evaluation on the Effect of Liners on the Physical Performance of the Antarctic Krill Trawl

Frontiers in Marine Science, 2022
The Antarctic krill (Euphausia superba) is one of the most abundant resources in the ocean, which provides food for several important species in the Antarctic Ocean, and is targeted commercially by humans for many decades.

Estimating Patagonian toothfish (Dissostichus eleginoides) length at first maturity from their age, sex and temperature experience around South Georgia

Journal of Fish Biology, EarlyView.
Abstract Patagonian toothfish (Dissostichus eleginoides) are a long‐lived, slow‐growing deep‐sea species endemic to the Southern Hemisphere and the focus of longline fisheries managed to ensure sustainable exploitation. Managing the fisheries relies on accurate stock assessments that include pertinent biological and exploitation processes.

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

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 ...

Dwarf Minke Whale (Balaenoptera acutorostrata) Mother and Calf Ecology in East and Southern Australia

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Knowledge of mother–calf pairs, migratory patterns, female reproductive cycles, and birth‐year calf development are all essential for understanding risks in these critical life stages and monitoring little‐known dwarf minke whale (Balaenoptera acutorostrata) populations.

Mascarene High Variability Shapes the Demography of a Wind‐Reliant Marine Top Predator

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Subtropical anticyclones are semi‐permanent atmospheric high‐pressure systems located in all five major ocean basins and are associated with large‐scale wind and weather patterns. They shape the physical environments of many species, yet their impacts on wildlife remain unexplored. We combined population and climate analyses to investigate the

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.

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 ...

Performance of a glider‐mounted multifrequency echosounder for measuring the vertical distribution and abundance of large pelagic copepods

Limnology and Oceanography: Methods, Volume 24, Issue 6, June 2026.
Abstract The difficulty of sampling zooplankton communities in situ has driven advancements in autonomous, remote sensing technology. The goal of this paper was to perform a gear comparison study testing the performance of one such piece of technology—a glider‐mounted four‐frequency echosounder—against traditional shipboard methods of measuring ...
