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.

LifeMet: Report on the 2024–2025 meteorite recovery expedition in Dronning Maud Land, Antarctica for the study of microbe–meteorite interactions

Meteoritics &Planetary Science, EarlyView.
Abstract Since the discovery of nine meteorites near the Yamato mountains in 1969, Antarctica has been recognized as a superb location for meteorite recovery. While Antarctic recovery expeditions prioritize meteorite preservation for mineralogical and planetary studies, meteorites are not typically collected for biological applications.

Modelling the impact of dominant transport pathways on Antarctic Krill fishing activity in the Southern Ocean.

PLoS ONE
Antarctic krill (Euphasia superba) are a key component in the Southern Ocean ecosystem, especially in the Atlantic sector, where the majority of the population is concentrated.

Surface elevation changes on Lachman Crags ice caps (north-eastern Antarctic Peninsula) since 1979 indicated by DEMs and ICESat data

Journal of Glaciology, 2019
The long-term warming on the Antarctic Peninsula in the second half of the 20th century prompted rapid retreat of glaciers on the peninsula and surrounding islands.

Gene flow in the Antarctic bivalve Aequiyoldia eightsii (Jay, 1839) suggests a role for the Antarctic Peninsula Coastal Current in larval dispersal

Royal Society Open Science, 2020
The Antarctic Circumpolar Current (ACC) dominates the open-ocean circulation of the Southern Ocean, and both isolates and connects the Southern Ocean biodiversity. However, the impact on biological processes of other Southern Ocean currents is less clear.

Cretaceous moss–cyanobacteria association reveals trophic interactions in polar forests of Antarctica

New Phytologist, EarlyView.
Kimmerera cyanifera gen. et sp. nov. with associated cyanobacteria, holotype UWBM 116051. Summary Through symbiotic associations with microbes, mosses play many important ecological roles in terrestrial ecosystems, such as facilitating trophic interactions and nitrogen cycling.

Interior Antarctica is undergoing marked climate change

Communications Earth & Environment
2024 is the warmest year in NASA’s 145-year climate record. Unlike the Arctic, which has experienced significantly faster warming than the global average, Antarctic temperature change is variable.

Enabling Under Ice Glider Operations: A Backseat Driver Approach

Journal of Field Robotics, Volume 43, Issue 5, Page 3292-3311, August 2026.
ABSTRACT Polar Oceans are key locations for forcing global ocean circulation, influencing both global climate and biogeochemical cycles. Due to restricted access to these seasonally and perennially ice‐covered regions, these areas are severely undersampled.

Role of extracellular carbonic anhydrase in the polar diatom Fragilariopsis cylindrus

New Phytologist, Volume 251, Issue 3, Page 1161-1171, August 2026.
Summary Diatoms are major primary producers in productive polar oceans, where cold temperatures and high CO2 solubility raise questions as to whether they rely on the CO2‐concentrating mechanism (CCM) to saturate photosynthesis. Knowledge of CCM function will help better predict the sensitivity of diatom primary production to warming and acidifying ...
