Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Antarctic Fish and Fisheries written by K.-H. Kock and published by Cambridge University Press. This book was released on 1992-09-10 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although Antarctic finfish have been exploited for more than two decades and many stocks now appear to be overfished, this is the first detailed account of this fishery. The book begins by giving a comprehensive description of Antarctic fish biology and ecology, the thorough understanding of which is a prerequisite to sound management of the fishery. Subsequent sections consider the course of finfish exploitation and the present state of exploited fish stocks in the Southern Ocean. The author concludes by proposing more effective management methods for the fish resources of the Southern Ocean in light of the Convention on the Conservation of Antarctic Marine Living Resources.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Antarctic Fish Biology written by Joseph T. Eastman and published by Academic Press. This book was released on 2013-10-22 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: BIOMASS (Biological Investigations of Marine Antarctic Systems and Stocks) was a unique, large-scale, long-term, international research programme established in 1977 to investigate the ecology of the Southern Ocean. Its main aim was to gain a greater understanding of the biological systems and stocks in the marine Antarctic environment, thereby providing a sound basis for the future management of the living resources within this immense ocean. The programme was drawn to a close in 1991 and its completion marked by a colloquium which brought together key researchers to summarise and review the results obtained. This volume, arising from that colloquium, provides a succinct, state-of-the-art account of the ecology of the Southern Ocean and serves as a comprehensive record of this unique and successful international project.

This book was released on 2013-11-11 with total page 825 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the third in aseries of publications devoted to the biogeographieal and ecological research in the Southern Hemisphere, published in the "Monographiae Biologicae". After dealing with Australia (vol. VIII) and Southern Africa (Vol. XIV) it was thought essential to include Antarctiea in this series. Ever since the expedition of the "Belgiea" made the first suc cessful wintering within the antarctie circle in 1898 and brought back a very rieh harvest of scientific data, Belgium kept a vivid interest in Antarctiea and took an active part in the modern and international exploration of this vast continent. As part of their programs for the International Geophysieal Year (I. G. Y. ) twelve nations established permanent or semi-permanent bases on the Antarctie Continent or on subantarctie islands. Thus a new era of vast and free international scientific collaboration in the Antarctie was opened and it culminated in the formulation and the signing of the Antarctic Treaty (Washington 1959). It was recognized and accepted that "Antarctiea" shall be used for peaceful purposes only and "Freedom of scientific investigation in Antarctiea and coopera tion toward that end, as applied during the I. G. Y. , shall continue . . " In order to organize this collaboration e. g. by full exchange of programs and resuIts a "Special Committee on Antarctie Research" (S. C. A. R. ) was founded in 1957.
Download or read book The Antarctic Silverfish a Keystone Species in a Changing Ecosystem written by Marino Vacchi and published by Springer. This book was released on 2017-05-03 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Frozen in Time written by Jeffrey D Stilwell and published by CSIRO PUBLISHING. This book was released on 2011-10-12 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: No other continent on Earth has undergone such radical environmental changes as Antarctica. In its transition from rich biodiversity to the barren, cold land of blizzards we see today, Antarctica provides a dramatic case study of how subtle changes in continental positioning can affect living communities, and how rapidly catastrophic changes can come about. Antarctica has gone from paradise to polar ice in just a few million years, a geological blink of an eye when we consider the real age of Earth. Frozen in Time presents a comprehensive overview of the fossil record of Antarctica framed within its changing environmental settings, providing a window into a past time and environment on the continent. It reconstructs Antarctica’s evolving animal and plant communities as accurately as the fossil record permits. The story of how fossils were first discovered in Antarctica is a triumph of human endeavour. It continues today with modern expeditions going out to remote sites every year to fill in more of the missing parts of the continent’s great jigsaw of life.

Available in PDF, EPUB and Kindle. Book excerpt: Atlantic menhaden, Brevootia tyrannus, the object of a major purse-seine fishery along the U.S. east coast, are landed at plants from northern Florida to central Maine. The National Marine Fisheries Service has sampled these landings since 1955 for length, weight, and age. Together with records of landings at each plant, the samples are used to estimate numbers of fish landed at each age. This report analyzes the sampling design in terms of probability sampling theory. The design is classified as two-stage cluster sampling, the first stage consisting of purse-seine sets randomly selected from the population of all sets landed, and the second state consisting of fish randomly selected from each sample set. Implicit assumptions of this design are discussed with special attention to current sampling procedures. Methods are developed for estimating mean fish weight, numbers of fish landed, and age composition of the catch, with approximate 95% confidence intervals. Based on specific results from three ports (Port Monmouth, N.J., Reedville, Va., and Beaufort, N.C.) for the 1979 fishing season, recommendations are made for improving sampling procedures to comply more exactly with assumptions of the sampling design. These recommendations include adopting more formal methods for randomizing set and fish selection, increasing the number of sets sampled, considering the bias introduced by unequal set sizes, and developing methods to optimize the use of funds and personnel.
