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.

Available in PDF, EPUB and Kindle. Book excerpt: The acclaimed science writer presents a wide-ranging exploration of Antarctica’s history, nature, and global significance in this “rollicking good read” (Kirkus). From the early expeditions of Ernest Shackleton to David Attenborough’s documentary series Frozen Planet, the continent of Antarctica has captured the world’s imagination. After the Antarctic Treaty of 1961, decades of scientific research revealed the true extent of its many mysteries. Now former Nature magazine staff writer Gabrielle Walker tells the full story of Antarctica—from its fascinating history to its uncertain future and the international teams of researchers who brave its forbidding climate. Drawing on her broad travels across the continent, Walker weaves all the significant threads of life on the vast ice sheet into a multifaceted narrative, illuminating what it really feels like to be there and why it draws so many different kinds of people. She chronicles cutting-edge science experiments, visits to the South Pole, and unsettling portents about our future in an age of global warming. “We are all anxious Antarctic watchers now, and Walker's book is the essential primer.”—The Guardian, UK

Download or read book Entomology of Antarctica written by J. Linsley Gressitt and published by American Geophysical Union. This book was released on 1967 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Antarctic Research Series, Volume 10. The existence of insects, mites, and their relatives on the antarctic continent is of great interest to many. These terrestrial arthropods may be said to be the dominant land animals in the absence of land vertebrates and many major groups of invertebrates. They are important in the simple food cycles which involve most segments of the land flora and microorganisms, and they play a part in soil formation. Thus a knowledge of their ecology is essential to the understanding of various biotic balances and processes. That several species live in the area of 85°S latitude in the face of harsh climatic factors is of great concern to the ecologist and the physiologist—therin lie many unanswered questions for future research.

Download or read book Antarctic Sea Ice Variability in the Southern Ocean Climate System written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2017-03-24 with total page 83 pages. Available in PDF, EPUB and Kindle. Book excerpt: The sea ice surrounding Antarctica has increased in extent and concentration from the late 1970s, when satellite-based measurements began, until 2015. Although this increasing trend is modest, it is surprising given the overall warming of the global climate and the region. Indeed, climate models, which incorporate our best understanding of the processes affecting the region, generally simulate a decrease in sea ice. Moreover, sea ice in the Arctic has exhibited pronounced declines over the same period, consistent with global climate model simulations. For these reasons, the behavior of Antarctic sea ice has presented a conundrum for global climate change science. The National Academies of Sciences, Engineering, and Medicine held a workshop in January 2016, to bring together scientists with different sets of expertise and perspectives to further explore potential mechanisms driving the evolution of recent Antarctic sea ice variability and to discuss ways to advance understanding of Antarctic sea ice and its relationship to the broader ocean-climate system. This publication summarizes the presentations and discussions from the workshop.

Download or read book Antarctic Lakes written by Johanna Laybourn-Parry and published by OUP Oxford. This book was released on 2014-08-14 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Antarctic continent carries the greatest diversity of lake environments on the planet: freshwater and saline lakes, tidal freshwater epishelf lakes, lakes on ice shelves and glacier surfaces, and over three hundred subglacial lakes; extraordinary ecosystems that have been separated from the atmosphere for up to millions of years. This book provides a unique and cutting edge synthesis of Antarctic limnology, drawing together current knowledge on geomorphology, morphometry, chemistry, community structure and function. It emphasises throughout the value of these near-pristine ecosystems as barometers of climate change, showing how responsive and vulnerable they are to the indirect impacts of anthropogenic activity. Antarctic Lakes begins with an introduction to their physical, chemical, and biological characteristics, providing a basis for understanding the subsequent detailed chapters on different lake types, and ends with a chapter considering the application of new technologies to polar limnology as well as identifying future research directions. This accessible text is suitable for both senior undergraduate and graduate students taking courses in Antarctic and polar limnology, and will also be of broad interest to researchers working in the areas of polar science, microbial ecology (and extremophiles), climatology, glaciology, and astrobiology.

Download or read book Whales of the Southern Ocean written by Yuri Mikhalev and published by Springer Nature. This book was released on 2020-01-28 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on actual data of Soviet whaling, and reliable methodologies that existed at the time when this monograph was written, it examines the distribution and migration patterns of whales of the Southern Ocean. It defines distinct populations on the basis of phenes, as well as whale breeding zones, which are located in the adjacent to the Southern Ocean waters at lower latitudes. The book records the presence of a new species of killer whale in the Southern Ocean - Orcinus nana. Prenatal growth patterns, pregnancy and lactation duration, mean sizes of new-born whales are determined. Methods for the graphic recording of registering structures are described, and an original method for their decoding is proposed to determine animal age. The age of sexual and physical maturity, life expectancy is determined. Earlier unknown “pair formations” on the lower jaw of baleen whales and sperm whales are described, together with their macro, histological and electronic microscopic structure. The impact of the extermination of whales on the Southern Ocean ecosystem is examined, recommendations for control of the current state of whale populations are given, and perspectives of whale population recovery are estimated. Regions that could be used as testing areas for whale registration method are defined. The book is intended for biologist-cytologists, ecologists and other specialists interested in cetaceans, and for biology students.

Download or read book Antarctica written by Tony Soper and published by Bradt Travel Guides. This book was released on 2018-03-19 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Updated throughout, the 7th edition of Bradt's Antarctica: a Guide to Wildlife is the most practical guide to the flora and fauna available for those 'going south'. Celebrating the amazing and often unique species of this spectacular environment, the title features chapters on the region's famous whales and penguins, and also on lesser known species such as skuas and sheathbills, with full coverage of plumage and identification. Each chapter is accompanied by vibrant illustrations from Dafila Scott to help bring species to life. Tony Soper's immaculate and engaging text remains the indispensible choice for the intrepid wildlife enthusiast. Antarctica's wildlife is under threat. The Southern Ocean is warming and the most obvious effect is on the continental ice shelves. Spectacular retreats and monster carvings from the west coast of the peninsula have been seen in recent decades. Less ice means fewer krill, which depend on the ice-edge for the algae which nourish them. In turn, this will impact on seal and whale numbers. In the case of penguins, while kings and macaronis, for instance, are doing well, the magnificently adapted and truly Antarctic species, Adélies and emperors, are in decline. In the case of emperors, maybe by as much as 50%. Bradt's Antarctica not only helps you to identify and understand species and habitats, it also explains the issues faced by this extraordinary continent, regarded by many as one of the most precious places on the planet.

Available in PDF, EPUB and Kindle. Book excerpt: Systems Biogeochemistry of Major Marine Biomes A comprehensive system-level discussion of the geomicrobiology of the Earth’s oceans In Systems Biogeochemistry of Major Marine Biomes, a team of distinguished researchers delivers a systemic overview of biogeochemistry across a number of major physiographies of the global ocean: the waters and sediments overlying continental margins; the deep sub-surfaces; the Arctic and Antarctic oceans; and the physicochemical extremes such as the hypersaline and sulfidic marine zones, cold methane seeps and hydrothermal ecosystems. The book explores state-of-the-art advances in marine geomicrobiology and investigates the drivers of biogeochemical processes. It highlights the imperatives of the unique, fringe, and cryptic processes while studying the geological manifestations and ecological feedbacks of in situ microbial metabolisms. Taking a holistic approach toward the understanding of marine biogeochemical provinces, this book emphasizes the centrality of culture-dependent and culture-independent (meta-omics-based) microbiological information within a systems biogeochemistry framework. Perfect for researchers and scientists in the fields of geochemistry, geophysics, geomicrobiology, oceanography, and marine science, Systems Biogeochemistry of Major Marine Biomes will also earn a place in the libraries of policymakers and advanced graduate students seeking a one-stop reference on marine biogeochemistry.

Download or read book Antarctic Ecosystems written by Alex D. Rogers and published by John Wiley & Sons. This book was released on 2012-02-28 with total page 585 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
