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

Ecological 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.

CS-PHOC: weekly census counts of Southern Ocean phocids at Cape Shirreff, Livingston Island

Scientific Data
Rapid climatic warming of the Antarctic Peninsula is driving regional population declines and distribution shifts of predators and prey. Affected species include Antarctic ice seals and the southern elephant seal, all of which rely on the peninsula ...

A contribution to the anatomy of two rare cetacean species: The hourglass dolphin (Cephalorhynchus cruciger) and the spectacled porpoise (Phocoena dioptrica)

The Anatomical Record, Volume 309, Issue 7, Page 1797-1820, July 2026.
Abstract The anatomical description of the hourglass dolphin (Cephalorhynchus cruciger) and the spectacled porpoise (Phocoena dioptrica) remains largely unexplored, due to limited specimen availability and preservation challenges. This study employed digital imaging techniques, conventional histology, and computed tomography to provide visualization of

On the Seaweeds from the Coast of Lutzow-Holm Bay, Antarctica

Antarctic Record, 1976
This paper is a note on the Antarctic seaweeds collected from the coast of Liitzow-Holm Bay in January 1975. A specimen of Desmarestia sp. (Fig. 1) was found washed ashore on the coast of Langhovde (Lat. 69°14'S, Long. 39°44'E).

An Assessment of Allelic and SNP Bias in a Genome‐Wide SNP Enrichment Kit for Killer Whales

Ecology and Evolution, Volume 16, Issue 7, July 2026.
This study evaluates ascertainment bias in a targeted SNP genotyping panel for killer whales (Orcinus orca) by comparing its performance against comprehensive whole genome sequencing data. Results indicate that while the targeted panel accurately recapitulates broad‐scale global population structure, it demonstrates lower fine‐scale resolution for ...

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

Ecology 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.

Geomorphology of Stansbury Peninsula, Nelson Island, Antarctic Peninsula

Journal of Maps
The proglacial landscapes of Antarctica offer critical insights into past and ongoing deglaciation processes and the impacts of climate change. This study presents the first geomorphological map of the proglacial part of Stansbury Peninsula (Rip Point) and Cariz Cabo Cape in the northern part of Nelson Island.

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

Environmental 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 ...

Interactions between vertical migration and local oceanography drive microplastic exposure for Antarctic krill

Scientific Reports
Euphausiids play important roles in ecosystems worldwide, transferring energy from primary producers to secondary consumers. Antarctic krill are the most abundant euphausiid on Earth and play important roles as critically important species in Southern ...

Killer whale predation on an Antarctic minke whale in the northern Antarctic Peninsula

Anais da Academia Brasileira de Ciências
We describe the seldom observed event of a group of type A killer whale (Orcinus orca) predating on an Antarctic minke whale (Balaenoptera bonaerensis) in austral summer 2019. A pod of 11-13 individuals was observed - and documented by photographs and video - as they killed and fed on the minke whale in the Bransfield Strait, northern Antarctic ...
