Muscle growth in Antarctic and Subantarctic notothenioid fishes
The suborder Notothenioidei comprises 122 species divided into 8 families, with members of 6 of the families living outside Antarctic waters. The Antarctic species underwent an extensive radiation from a small demersal ancestor to occupy different ...

Role of the Dissostichus mawsoni LeptinB Gene in Cellular Cold Resistance
Variation in fish temperature is determined by changes in the external aquatic environment, and temperature serves as a crucial regulatory factor for the behavior, physiology, and molecular processes of fish.

Genomics of cold adaptations in the Antarctic notothenioid fish radiation
Abstract 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, we generated and analysed new genome assemblies for 24 species covering all major subgroups of the radiation. We present

Sequence and structure comparison of ATP synthase F0 subunits 6 and 8 in notothenioid fish.
Mitochondrial changes such as tight coupling of the mitochondria have facilitated sustained oxygen and respiratory activity in haemoglobin-less icefish of the Channichthyidae family.

CONTRIBUTION OF POLYCHAETES (ANNELIDA: POLYCHAETA) IN THE DIET OF THREE NOTOTHENIOIDS SPECIES (PERCIFORMES: NOTOTHENIOIDEI) FROM THE MAGELLAN REGION [PDF]
The importance of polychaeta in the diet of three notothenioids of western Patagonia we determined. By summarizing information published, regarding Patagonotothen tessellata, P. cornucola and Harpagifer bispinis.

Mitochondrial function in Antarctic nototheniids with ND6 translocation.
Fish of the suborder Notothenioidei have successfully radiated into the Southern Ocean and today comprise the dominant fish sub-order in Antarctic waters in terms of biomass and species abundance. During evolution in the cold and stable Antarctic climate,

Evolution in chronic cold: varied loss of cellular response to heat in Antarctic notothenioid fish
Background Confined within the freezing Southern Ocean, the Antarctic notothenioids have evolved to become both cold adapted and cold specialized. A marked signature of cold specialization is an apparent loss of the cellular heat shock response (HSR). As

Bony fish genomes: Status and gaps
Abstract Bony fish constitute an exceptionally species‐rich group of aquatic vertebrates, comprising more than 95% of all living fish. The adaptive processes on the diversity of environments they inhabit make them a highly diverse group from taxonomic, morphological and evolutionary standpoints.

Abstract We used an ecological niche theory framework integrating physiological and behavioural ecology to understand interspecific differentiation of juveniles of four Antarctic fishes: Trematomus bernacchii, Trematomus pennellii, Trematomus nicolai and Pagothenia borchgrevinki.

Non-Antarctic notothenioids: Past phylogenetic history and contemporary phylogeographic implications in the face of environmental changes [PDF]
The non-Antarctic Notothenioidei families, Bovichtidae, Pseudaphritidae and Eleginopsidae, diverged early from the main notothenioid lineage. They are important in clarifying the early evolutionary processes that triggered notothenioid evolution in the ...
