Ecological implications and lessons from high pathogenicity avian influenza H5N1 2.3.4.4b in Antarctica

open access: yesEcological Solutions and Evidence, Volume 7, Issue 3, July–September 2026.
HPAI H5N1 was confirmed in 22 South Polar Skuas and one Kelp Gull on Dismal and Horseshoe Islands, Marguerite Bay, Western Antarctic Peninsula in early 2025, with high mortalities consistent with global trends. Rapid antigen tests showed 90% agreement with rRT‐PCR, supporting their utility for early detection in remote environments.

Recombinant Protein Expression in Rhodococcus species

open access: yesCurrent Protocols, Volume 6, Issue 7, July 2026.
Abstract Producing recombinant bacterial proteins is essential for elucidating their structure and function, making efficient overexpression systems a key requirement. Escherichia coli is widely used for this purpose, particularly for bacterial proteins, but certain targets remain challenging to express or obtain as soluble protein.

Dynamic Migratory Strategies and Foraging Habitats of Southern Right Whales Revealed by Satellite Telemetry

open access: yesEcology and Evolution, Volume 16, Issue 7, July 2026.
Satellite‐linked tags on 34 southern right whales revealed basin‐scale movements and foraging concentrated in the ACC, Crozet Islands, Benguela system, and the highly variable seasonal ice zone. Environmental modelling revealed environmental drivers behind foraging decisions, and identified key ecosystems.

Metabarcoding of Broad‐Diet Nototheniid Fish Stomachs Reveals Newly Detected Antarctic Parasite Signals and Potential Host Associations

open access: yesEnvironmental DNA, Volume 8, Issue 4, July‐August 2026.
Using 18S rDNA metabarcoding of stomach contents from two Antarctic nototheniid fishes, we detected 242 parasite OTUs. Protists dominated diversity, metazoans dominated abundance, and depth structured assemblages. Novel parasite–host associations and previously unreported pathogenic protists highlight fish metabarcoding as a tool for biodiversity and ...

Opportunistic feeding by Antarctic krill in the eastern Weddell Gyre

open access: yesLimnology 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 ...

The Age and Origin of Block Deposits in the Victorian Alps, Australia

open access: yesPermafrost and Periglacial Processes, Volume 37, Issue 3, Page 391-415, July/September 2026.
ABSTRACT Large periglacial block deposits are found in the mountains of southeastern Australia. Despite their widespread distribution, their mode of formation and age are poorly understood. These landforms hold considerable potential to shed light on the nature of cooling during glacial periods. In this paper we present a new study of block deposits in

Multiproxy Chronologies of the Hurd Rock Glacier (Livingston Island, South Shetland Islands, Maritime Antarctica): Between the Late‐Stage Stabilization and Flow Deceleration

open access: yesPermafrost and Periglacial Processes, Volume 37, Issue 3, Page 535-550, July/September 2026.
ABSTRACT The Hurd Rock Glacier, located on Livingston Island (South Shetland Islands archipelago, Maritime Antarctica), is a tongue‐shaped feature composed of angular boulders, displaying transverse ridges and furrows, and featuring lobate structures, which are more prominently developed in its frontal sector.
