Underwater Photographic Survey of Coastal Fish Community of Terra Nova Bay, Ross Sea
Diversity, 2022 Although the extent of near-shore and coastal habitats around the Antarctic Continent is limited, they host an abundant and diversified fish fauna dominated by notothenioids.

Pathways to polar adaptation in fishes revealed by long‐read sequencing
Molecular Ecology, Volume 32, Issue 6, Page 1381-1397, March 2023., 2023 Abstract Long‐read sequencing is driving a new reality for genome science in which highly contiguous assemblies can be produced efficiently with modest resources. Genome assemblies from long‐read sequences are particularly exciting for understanding the evolution of complex genomic regions that are often difficult to assemble.

Diversity, 2021 Trematomus species (suborder Notothenioidei; family Nototheniidae) are widely distributed in the southern oceans near Antarctica. There are 11 recognized species in the genus Trematomus, and notothenioids are known to have high chromosomal diversity (2n =

Ecology and Evolution, Volume 12, Issue 7, July 2022., 2022 We used scale worms as a representative group for Antarctic marine benthic animals to better understand their evolutionary history, and possibly predict how they could respond to warming temperatures. Using genetic barcode data from over 600 scale worms, we were able to comprehend the history of this group during past warming and cooling geological ...

Journal of Anatomy, Volume 240, Issue 1, Page 34-49, January 2022., 2022 Antarctic icefishes are amazing examples of evolutionary adaptation. Here, we show quantitatively that icefish skeletons did not change bone microstructure or bone mineral density, relative to closely related fish species. Abstract Ancestors of the Antarctic icefishes (family Channichthyidae) were benthic and had no swim bladder, making it ...

Diversity and Distributions, Volume 27, Issue 5, Page 766-783, May 2021., 2021 Abstract Aim The species of the genus Chionodraco (Notothenioidei) are the most abundant icefish on the continental shelf of the Weddell Sea. While previous studies indicated that only Chionodraco hamatus and Chionodraco myersi inhabit the Weddell Sea, the third Chionodraco species, Chionodraco rastrospinosus, was recently sampled in the area.

Allocation of the diet of the Argentine Islands’ inshore ichthyofauna
Biosystems Diversity, 2021 Fish diets are important indicators of ecosystem change. This aspect of the ichthyofauna of the coast of the Argentine Islands has been insufficiently studied in comparison with other regions.

Eocene relatives of cod icefishes (Perciformes: Notothenioidei) from Seymour Island, Antarctica [PDF]
, 2013 Fragmentary skull bones and vertebra from the Upper Eocene La Meseta Formation on Seymour (Marambio) Island, Antarctic Peninsula have been described as gadiform fishes, informally named “Mesetaichthys”.
