Antarctic Fish Biology. Evolution in a Unique Environment by Joseph T. Eastman

By Joseph T. Eastman

This crucial quantity presents an unique synthesis and novel review of Antarctic fish biology, detailing the evolution of those fish in one of the most strange and severe environments on the planet. concentrating on one crew of fish, the notothenoioids, which include nearly all of the present organismal range, this ebook describes a fauna that has advanced in isolation and skilled impressive adaptive radiation by means of buying various physiological specializations. Darwin's finches and African cichlids should be joined via Antarctic fishes as exemplars of adaptive radiation.
The books' assurance is exact and entire, and the writer in actual fact acknowledges the truth that those fish are an element of a finest and biologically distinct surroundings and atmosphere. issues in Antarctic Fish Biology comprise previous and current environments, fossil documents, taxonomic composition of fauna, systematic relationships, diversification, and physiological variations

From teeth or tooth plates, he distinguished a cutlassfish (Trichiuridae) similar to Trichiurus (Long, 1991) and a large (over 60 cm SL) wrasse (Labridae) (Long, 1992b). The fish fossils from Seymour Island indicate that the late Eocene fauna consisted of representatives of cosmopolitan groups. The fauna predates the isolation of Antarctica. Some representatives, like the gadiform, may have had Tethyan affinities. These late Eocene fishes lived in temperate seas and were antecedent to the notothenioids that later dominated the fish fauna under the cold conditions of the Neogene.

3 lists notothenioids endemic to these islands. The East Antarctic Province includes the shelf waters of most of the continent except for the Antarctic Peninsula. There are relatively few islands, and shelf area is limited except in the vicinity of the Weddell and Ross Seas. As mentioned previously, the shelf is also exceptionally deep. Water tempera­ tures are colder than in any other province and the heavy ice cover has prevented the establishment of a littoral fauna. The nototheniid genus Trematomus is diverse and characteristic of this province.

Did it include nonnotothenioids (other than liparidids and zoarcids) that are not represented today in the subzero inshore waters? V. y. Like the continent itself, the fish faunas have changed remarkably through geologic time. The various fossil faunas are different in taxonomic 36 3 The Fossil Fish Faunas composition and paleoecology, separated by large gaps in geologic time, and not ancestral to each other. Paleozoic fishes are represented by most higher taxonomic groups in existence at that time and indicate that Antarctica was an integral part of Gondwana.
