Antarctic Fish Biology: Evolution in a Unique Environment
  • J. Eastman
  • Environmental Science, Biology
  • 17 June 1993
TLDR
This book discusses the origins and evolution of the Modern Fauna, as well as the relationships between Notothenioids, the Fossil Fish Faunas, and the Zoogeography of Antarctica.

The nature of the diversity of Antarctic fishes
TLDR
The species diversity of the Antarctic fish fauna changed notably during the ≈40 million years from the Eocene to the present, and in some notothenioid clades phyletic diversification was accompanied by considerable morphological and ecological diversification.

Ancient climate change, antifreeze, and the evolutionary diversification of Antarctic fishes
TLDR
The results challenge the current understanding of the evolution of Antarctic notothenioids suggesting that the ecological opportunity that underlies this adaptive radiation is not linked to a single trait, but rather to a combination of freeze avoidance offered by AFGPs and subsequent exploitation of new habitats and open niches created by increased glacial and ice sheet activity.

Fishes on the Antarctic continental shelf : evolution of a marine species flock?
TLDR
Notothenioids are one of the first recognized examples of a species flock of marine fishes and calculations made of the time required for speciation (TFS) for nototinioids of the family Channichthyidae are slower than for most lacustrine species flocks but similar to estimates for island radiations of birds and arthropods.

The role of notothenioid fish in the food web of the Ross Sea shelf waters: a review
TLDR
The Ross Sea, a large, high-latitude (72–78°S) embayment of the Antarctic continental shelf, averages 500 m deep, with troughs to 1,200 m and the shelf break at 700 m, and the food web is non-linear, with complex prey-predator interactions.

Antarctic notothenioid fishes as subjects for research in evolutionary biology
  • J. Eastman
  • Environmental Science
    Antarctic Science
  • 1 September 2000
TLDR
The benthic fish fauna of the shelf and upper slope of the Antarctic Region includes 213 species with higher taxonomic diversity confined to 18 families, and notothenioids exhibit the disproportionate speciosity and high endemism characteristic of fish species flock.

Decadal trends in abundance, size and condition of Antarctic toothfish in McMurdo Sound, Antarctica, 1972–2011
We report the analyses of a dataset spanning 39 years of near-annual fishing for Dissostichus mawsoni in McMurdo Sound, Antarctica, 1972–2011. Data on total length, condition and catch per unit…

Pleuragramma antarcticum (Pisces, Nototheniidae) as food for other fishes in McMurdo Sound, Antarctica
  • J. Eastman
  • Environmental Science
    Polar Biology
  • 1 September 1985
TLDR
Nine spcies of notothenioid fishes were captured near the southern limit of their range in ice covered McMurdo Sound, Antarctica, and Pleuragramma was the most common prey fish consumed, being present in stomachs of 4 of 8 species.

Diversity, relative abundance, new locality records and population structure of Antarctic demersal fishes from the northern Scotia Arc islands and Bouvetøya
TLDR
Five of the six notothenioid species at Bouvetøya are not genetically differentiated from other localities in the Atlantic sector of the Southern Ocean, and the location of Bouvet €ya within the Antarctic Circumpolar Current and the long pelagic stages of the notOThenioids at Bouveøya may be at least partly responsible for this genetic homogeneity.

Late Eocene gadiform (Teleostei) skull from Seymour Island, Antarctic Peninsula
On the basis of a skull from the late Eocene La Meseta Formation on Seymour Island, Antarctic Peninsula, a gadiform fish is reported from the Antarctic region for the first time. This specimen, the…
