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.

Krill, or euphausiids, a group of immense importance in marine ecosystems, comprises over 80 species, most of which are planktonic. Krill are widespread with species to be found in all the oceans of the world. Their numerical density in some regions increases their importance to marine ecosystems and has led to commercially successful krill harvesting. This comprehensive volume, thoroughly edited by Inigo Everson, well known for his work in this area, comprises chapters written by internationally acknowledged experts. The contents include coverage of: sampling and distribution, population, aggregation, reproduction and the role of krill in the ecosystem. Further specific chapters include krill harvesting, products and details of management in Japanese, Canadian and Southern Ocean waters. Drawing on the experience in each, the ecosystem approach to management is discussed in detail and how it might be applied more widely for example in forage fisheries. This most important volume draws together, for the first time, a vast amount of vital information for all those involved in work on these important marine organisms. Krill will be of great use to fisheries scientists, marine biologists and ecologists, oceanographers, zoologists and invertebrate biologists and all those involved in the commercial harvesting, exploitation and management of krill, world wide. Libraries in all aquatic and marine research stations and universities where marine and fisheries sciences are studied and taught should have multiple copies of this landmark publication on their shelves. Contributions from internationally-recognised experts in the field. Well-edited to provide an accessible and user-friendly book. Krill are a key part of ocean ecosystems. Part of exciting new Blackwell Science Series.

First published in 1993, The Biology of the Southern Ocean has been referred to as international research at its best and an invaluable reference. Drawing on the considerable volume of information published in the last ten years, this second edition retains the format that made the first edition a popular bestseller, while updating the information with the latest research results available. The book begins with a description of the physico-chemical environment and, in a logical sequence, covers phytoplankton and primary production, the sea ice microbial communities and the secondary consumers, the zooplankton. The author includes an extended chapter on the biology and ecology of Antarctic krill that highlights its central position in the Southern Ocean food web. A series of chapters consider the higher consumers, nekton (with an emphasis on cephalopods) fish, seals, whales, and seabirds. The following chapters explore selected ecosystem components; the benthic communities, life beneath the fast ice and ice shelves, recent advances in understanding decomposition processes, and the role of bacteria and protozoa. The author synthesizes ecosystem dynamics, with an emphasis on the pelagic ecosystem. He covers resource exploitation, the impact of such exploitation on the marine ecosystem, and the problems involved in the management of the living resources. His epilogue summarizes the extent to which our understanding of the functioning of the Antarctic marine ecosystem has changed in the last 50 years; for example, there has been a dramatic change in our view of krill and its role in the Southern Ocean marine ecosystem. The book concludes with the statement that research carried out under the AGCS Programme and the Scientific Committee on Antarctic Research (SCAR) will continue to provide critical information on the functioning of Antarctic marine ecosystems. Intended for all those with an ongoing interest in Antarctic research, conservation, and management, this volume represents one of the most authoritative resources in the field as it covers all aspects of this important marine ecosystem.

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.

"Scientists say they are one of most abundant animals on the planet. But when pressed, few people can accurately describe krill or explain their ecological importance. Antarctic krill have used their extraordinary adaptive skills to survive and thrive for millions of years in a dark, icy world far from human interference. But with climate change melting ice caps at the top and bottom of the world, and increased human activity and pollution, their evolutionary flexibility to withstand these new pressures may not be enough. Eminent krill scientist Stephen Nicol wants us to know more about this enigmatic creature of the sea. He argues that it's critical to understand krill's complex biology in order to protect them as the krill fishing industry expands. Ocean enthusiasts will come away with a newfound appreciation for the complex ecology of a species we have much to learn from, and many reasons to protect."--Provided by publisher.

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.
