Book Description
Since its discovery Antarctica has held a deep fascination for biologists. Extreme environmental conditions, seasonality and isolation have lead to some of the most striking examples of natural selection and adaptation on Earth. Paradoxically, some of these adaptations may pose constraints on the ability of the Antarctic biota to respond to climate change. Parts of Antarctica are showing some of the largest changes in temperature and other environmental conditions in the world. In this volume, published in association with the Royal Society, leading polar scientists present a synthesis of the latest research on the biological systems in Antarctica, covering organisms from microbes to vertebrate higher predators. This book comes at a time when new technologies and approaches allow the implications of climate change and other direct human impacts on Antarctica to be viewed at a range of scales; across entire regions, whole ecosystems and down to the level of species and variation within their genomes. Chapters address both Antarctic terrestrial and marine ecosystems, and the scientific and management challenges of the future are explored.

Book Description
This book gives a unique insight into the current knowledge of krill population dynamics including distribution, biomass, production, recruitment, growth and mortality rates. Detailed analysis is provided on food and feeding, reproduction and krill behaviour. The volume provides an overview on the aspects of natural challenges to the species, which involve predation, parasites and the commercial exploitation of the resource and its management. A chapter on genetics shows the results of population subdivision and summarizes recent work on sequencing transcriptomes for studying gene function as part of the physiology of live krill. The focus of Chapter 4 is on physiological functions such as biochemical composition, metabolic activity and growth change with ontogeny and season; and will demonstrate which environmental factors are the main drivers for variability. Further discussed in this chapter are the bottle necks which occur in the annual life cycle of krill, and the mechanisms krill have adapted to cope with severe environmental condition.

Book Description
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.

Book Description
Antarctic Ecosystems comprises 55 papers presented at the Fifth Symposium on Antarctic Biology held under the auspices of the Scientific Committee on Antarctic Research (SCAR) in Hobart, Australia, 29 August - 3 September, 1988. Both short- and long-term changes in ecosystems and community structures caused by natural and human factors were discussed to help understand the ecological processes taking place in a changing environment. The variability of ecological factors must be known for the development of realistic monitoring strategies and sound conservation practices.

Book Description
The book is based on results from the Russian expedition in the region of the Antarctic Peninsula and Powell Basin in the northern part of the Weddell Sea, as well as on the review of earlier research in the region. The main goal of the research was to collect the newest data and study the physical properties and ecology of this key region of the Southern Ocean. Data analysis is supplemented with numerical modeling of the atmosphere-ocean interaction and circulation in the adjacent region, including research on rogue waves. The focus of the study was the Antarctic Circumpolar Current, currents and water properties in the Bransfield Strait and Antarctic Sound, properties of seawater, currents, ecosystem and biological communities in the Powell Basin of the northwestern Weddell Sea, and their variations. An attempt is made to reveal the role of various components of the Antarctic environment in the formation of biological productivity and maintenance of the Antarctic krill population. This is especially important as in the last decades the Antarctic environment has experienced significant changes related to the global climatic trends.

Book Description
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.

Book Description
Antarctica and the Southern Ocean cover one-tenth of the earth's surface. In a legal and environmental sense, Antarctica represents the geography of hope. It is the freshest and most pristine of regions, governed by a legal regime that offers Antarctica and its circumpolar water the unique possibility of becoming the world's first global wilderness preserve. But in today's age of resource scarcity, Antarctica still provokes much political, economic and legal debate. Over the past decade, international attention has increasingly focused on the legal status of the continent, the potential for hydrocarbon exploitation offshore, and opportunities for harvesting circumpolar living marine resources. In this fascinating treatment, Christopher C. Joyner undertakes the first serious examination of the intimate relationship between Antarctica and the law of the sea. Using Antarctica as a case study, Joyner probes large conceptual issues of ocean law and politics. He uses the intricate details of oceanography and law to unravel the dynamics of the Antarctic Treaty System. In doing so, he examines how the changing importance of Antarctic issues has affected the development of the law of the sea for the region, the ways in which states define their national interests, and the accommodation through various negotations that have contributed to the development of law for governing the Southern Ocean. While the study of law for the Antarctic is provocative in itself, this work goes much farther. The study critically analyzes the region's biogeography, the condition of sovereignty on the continent, the lawfulness of asserting jurisdictional zones offshore, and various legal implications for Antarctica's continental shelf, local island groups, circumpolar deep seabed, and the Southern Ocean's high seas. Moreover, the special legal efforts by the international community to protect the Antarctic seas from marine pollution and to conserve its living marine resources are comprehensively appraised. Thorough, authoritative, and objectively reasoned, Antarctica and the Law of the Sea provides an insightful assessment of how law can progressively develop for a resource-rich region of the world's ocean. As such, it should appeal to a broad range of international lawyers and social scientists who are interested in international relations, political economy, environmental politics, and the law of the sea.

Book Description
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.
