Biology of Antarctic Fish presents the most recent findings on the biology of fish in the unique environment of the Antarctic ocean. At present the year-round temperature of the coastal waters is very near -1,87 ° C, the equilibrium temperature of the ice-seawater mixture. This extremely low temperature affects different levels of organization of fish life: individuals, organ systems, cells, organelles, membranes, and molecules. Exploring ecology, evolution, and life history as well as physiology, biochemistry, and molecular biology of Antarctic fish the book describes the mechanisms of cold adaptation at all these levels. It provides material for discussion also for fundamental questions in the field of adaptation to an extreme environment and therefore is of particular interest not only to specialized scientists, but also to those involved in basic and evolutionary biology.

Antarctic Fish Biology

ISBN: 9781483288444
Release Date: 2013-10-22
Genre: Science

This important volume provides an original synthesis and novel overview of Antarctic fish biology, detailing the evolution of these fish in some of the most unusual and extreme environments in the world. Focusing on one group of fish, the notothenoioids, which contain the majority of the current organismal diversity, this book describes a fauna that has evolved in isolation and experienced incredible adaptive radiation by acquiring numerous physiological specializations. Darwin's finches and African cichlids may be joined by Antarctic fishes as exemplars of adaptive radiation. The books' coverage is detailed and comprehensive, and the author clearly recognizes the fact that these fish are a component of a most interesting and biologically unique ecosystem and environment. Topics in Antarctic Fish Biology include past and present environments, fossil records, taxonomic composition of fauna, systematic relationships, diversification, and physiological adaptations.

Genre: Science

The Antarctic fish fauna has evolved over a long period of geographic and climatic isolation. In the course of this evolution, Antarctic fish have developed specialized adaptations, some of which characterize these organisms as unique. In strong contrast to the continental shelf faunas elsewhere, the Antarctic shelf ichthyofauna is dominated by a single highly endemic group, the Notothenioidei. This group of perciform fish probably first appeared and diversified in the early Tertiary. The development of the Polar Front (referred to as the Antarctic Convergence in the older literature) resulted in a natural oceanographic barrier to migration in either direction, and thus became a key factor in the evolution of Antarctic fish. The dominance of the Antarctic continental shelf fauna by a single taxonomic group of fish provides a simplified natural laboratory for exploring the wealth of physiological, biochemical and ecological adaptations that characterize the fauna. Understanding of the patterns of adaptation in this highly specialized group of fish can tell us much about of evolution.

The Antarctic Silverfish a Keystone Species in a Changing Ecosystem

ISBN: 9783319558936
Release Date: 2017-06-02
Genre: Science

This book encompasses the body of available scientific information on the notothenioid fish Pleuragramma antarctica commonly known as Antarctic silverfish. This plankton-feeder of the intermediate trophic level is the most abundant fish in the coastal regions of high Antarctica, and plays a pivotal ecological role as the main prey of top predators like seals, penguins, whales and Antarctic toothfish. Broad circum-polar distribution, a key role in the Antarctic shelf pelagic ecosystem, and adaptations makes understanding the species’ likely response to environmental change relevant to foresee the potential responses at the local ecosystem level. Additionally, a detailed understanding of the abundance and trophic interactions of such a dominant keystone species is a vital element of informing the development of marine spatial planning and marine protected areas in the Antarctic continental shelf region. Experts in the field provide here unique insights into the evolutionary adaptation, eco-physiology, trophic ecology, reproductive and population ecology of the Antarctic silverfish and provide new clues about its vulnerability in facing the challenges of the ongoing environmental changes.

Release Date: 2003-07-08
Genre: Science

As we enter the twenty-first century, the polar biological sciences stand well poised to address numerous important issues, many of which were unrecognized as little as 10 years ago. From the effects of global warming on polar organisms to the potential for life in subglacial Lake Vostok, the opportunities to advance our understanding of polar ecosystems are unprecedented. The era of "genome-enabled" biology is upon us, and new technologies will allow us to examine polar biological questions of unprecedented scope and to do so with extraordinary depth and precision. Frontiers in Polar Biology in the Genomic Revolution highlights research areas in polar biology that can benefit from genomic technologies and assesses the impediments to the conduct of polar genomic research. It also emphasizes the importance of ancillary technologies to the successful application of genomic technologies to polar studies. It recommends the development of a new initiative in polar genome sciences that emphasizes collaborative multidisciplinary research to facilitate genome analyses of polar organisms and coordinate research efforts.

Southern Ocean Ecology

Genre: Nature

An international research project known as Biological Investigations of Marine Antarctic Systems and Stocks or BIOMASS was a unique, 15-year, international research program established to investigate the ecology of the Southern Ocean. This volume summarizes the results of this monumental research effort and provides a succinct, state-of-the-art account of the ecology of the Southern Ocean, covering the physical marine environment, marine stocks (phytoplankton, zooplankton, krill, fish, and birds), marine systems, and future research endeavors.
