Antarctic blackfin icefish genome reveals adaptations to extreme environments [PDF]

open access: yesNature Ecology & Evolution, 2019
AbstractIcefishes (suborder Notothenioidei; family Channichthyidae) are the only vertebrates that lack functional haemoglobin genes and red blood cells. Here, we report a high-quality genome assembly and linkage map for the Antarctic blackfin icefish Chaenocephalus aceratus, highlighting evolved genomic features for its unique physiology.

Characterization of the Gut Microbiota of Mackerel Icefish, Champsocephalus gunnari

open access: yesFishes, 2022
The gut microbiome of Antarctic fish species has rarely been studied due to difficulties in obtaining samples. The mackerel icefish, Champsocephalus gunnari, primary feeds on krill and is one of the key species in the food web of the Southern Ocean.

Gap-free genome assembly of Salangid icefish Neosalanx taihuensis

open access: yesScientific Data, 2023
Neosalanx taihuensis is widely distributed in freshwater and brackish water areas in China. Due to its high commercial value, it has been artificially introduced into many lakes and reservoirs, showing strong ecological adaptability.

The heart of the icefish: bioconstruction and adaptation.

open access: yesBrazilian journal of medical and biological research = Revista brasileira de pesquisas medicas e biologica, 1995
The Channichthyidae or "icefish" represent an intriguing example of extreme adaptation to the stable low temperature and high oxygen content of the Antarctic waters. The lack of respiratory pigments (hemoglobin and myoglobin) in these teleosts is associated with relatively low oxygen consumption and relevant cardio-circulatory adjustments which include

The mitochondrial genome of clearhead icefish Protosalanx chinensis (Salmoniformes: Salangidae) [PDF]

open access: yesMitochondrial DNA. Part B. Resources, 2018
The complete mitochondrial genome of Protosalanx chinensis was determined to be 16,879 bp in length. It consists of 13 protein-coding genes, 22 tRNAs, 2 ribosomal RNAs, and a control region.

Feeding Behaviour of Seven Icefish Species (Channichthyidae) in the Ross Sea, Antarctica

open access: yesFishes
The Channichthyidae, a monophyletic fish group belonging to the suborder Notothenioidei, are uniquely adapted to the polar environment. However, while their physiology has been extensively studied, studies on their ecology are relatively rare.

Twenty-First-Century Environmental Change Decreases Habitat Overlap of Antarctic Toothfish (Dissostichus mawsoni) and Its Prey. [PDF]

open access: yesGlob Chang Biol
Antarctic toothfish are a commercially exploited upper‐level predator in the Southern Ocean, but knowledge on how Antarctic toothfish and its prey respond to environmental change remains incomplete. In this study, we employ the extended aerobic growth index to quantify changes in predator–prey viable habitat overlap in response to changes in ...

Are Sponges Good Natural Sentinels for Monitoring Fish Diversity in Antarctic Coastal Waters? [PDF]

open access: yesEcol Evol
This study demonstrates that eDNA metabarcoding using both water and sponge samples is an effective tool for monitoring fish biodiversity along the Western Antarctic Peninsula. The results revealed 14 endemic Antarctic fish species and one marine mammal, with water samples often offering a more comprehensive view than sponges.

The “icefish paradox.” Which is the task of neuroglobin in Antarctic hemoglobin‐less icefish? [PDF]

open access: yesIUBMB Life, 2008
Is There an Answer? is intended to serve as a forum in which readers to IUBMB Life may pose questions of the type that intrigue biochemists but for which there may be no obvious answer or one may be available but not widely known or easily accessible. Readers are invited to e-mail ascenzi@uniroma3.it if they have questions to contribute or if they can ...
