Temperature activated transient receptor potential ion channels from Antarctic fishes [PDF]
Open Biology, 2023 Antarctic notothenioid fishes (cryonotothenioids) live in waters that range between −1.86°C and an extreme maximum +4°C. Evidence suggests these fish sense temperature peripherally, but the molecular mechanism of temperature sensation in unknown ...

Population genomics of an icefish reveals mechanisms of glacier-driven adaptive radiation in Antarctic notothenioids [PDF]
BMC Biology, 2022 Background Antarctica harbors the bulk of the species diversity of the dominant teleost fish suborder—Notothenioidei. However, the forces that shape their evolution are still under debate.

Multiple Pathways of Visual Adaptations for Water Column Usage in an Antarctic Adaptive Radiation [PDF]
Ecology and EvolutionEvolutionary transitions in water column usage have played a major role in shaping ray‐finned fish diversity. However, the extent to which vision‐associated trait complexity and water column usage is coupled remains unclear.

Are Sponges Good Natural Sentinels for Monitoring Fish Diversity in Antarctic Coastal Waters? [PDF]
Ecology and EvolutionMonitoring biodiversity in Antarctic ecosystems poses significant challenges, particularly due to the harsh environment. Traditional methods, such as beach seines, are time‐consuming, resource‐intensive, and difficult to carry out in Antarctica.

Genomics of cold adaptations in the Antarctic notothenioid fish radiation [PDF]
Nature Communications, 2023 Numerous novel adaptations characterise the radiation of notothenioids, the dominant fish group in the freezing seas of the Southern Ocean. To improve understanding of the evolution of this iconic fish group, here we generate and analyse new genome ...

Novel mitochondrial genome rearrangements including duplications and extensive heteroplasmy could underlie temperature adaptations in Antarctic notothenioid fishes [PDF]
Scientific Reports, 2023 Mitochondrial genomes are known for their compact size and conserved gene order, however, recent studies employing long-read sequencing technologies have revealed the presence of atypical mitogenomes in some species.

Identification of two miRNAs regulating cardiomyocyte proliferation in an Antarctic icefish [PDF]
iScienceSummary: The hemoglobinless Antarctic icefish develop large hearts to compensate for reduced oxygen-carrying capacity, which serves as a naturally occurred model to explore the factors regulating cardiogenesis.

Comparative analysis of length-weight relationships and condition factors of two congeneric rockcod species from the shores of King George Island, Antarctica [PDF]
PeerJLength-weight relationships (LWR) and Fulton’s condition factors (K) of two notothenioid species, Notothenia rossii and Notothenia coriiceps, were assessed using 295 and 148 specimens, respectively.

Developmental constraint shaped genome evolution and erythrocyte loss in Antarctic fishes following paleoclimate change. [PDF]
PLoS Genetics, 2020 In the frigid, oxygen-rich Southern Ocean (SO), Antarctic icefishes (Channichthyidae; Notothenioidei) evolved the ability to survive without producing erythrocytes and hemoglobin, the oxygen-transport system of virtually all vertebrates.
