DOWNLOAD EBOOK →This is the first book to describe the ecology of high latitude lakes, rivers and glacial environments in both the North and South polar regions. From the lake-rich floodplains of the Arctic to the deep, enigmatic waters of Lake Vostok, Antarctica, these regions contain some of the most extraordinary aquatic ecosystems on Earth. They provide a fascinating diversity of habitats for plant, animal and microbial communities, and are proving to be valuable model systems for exploring many ecological themes including landscape-lake interactions, adaptation of life to environmental extremes, and controls on the structure and functioning of aquatic ecosystems. Some of these waters also have direct global implications, including permafrost thaw lakes as sources of greenhouse gases, subglacial aquatic environments as a storehouse of ancient microbes, and Arctic rivers as major inputs of freshwater and organic carbon to the World Ocean. Given that many polar areas are experiencing greater climate warming than at lower latitudes, these ecosystems can also be viewed as sentinels of global change. This timely volume brings together many of the world's leading researchers in polar limnology to describe these diverse aquatic environments and their ecology. It introduces each major ecosystem type, examines the similarities and differences between Arctic and Antarctic systems as well as their responses to environmental change, and describes new frontiers for future research. A glossary of terms is provided for non-specialists, and a set of colour plates introduces the ecosystems and their biota. Polar Lakes and Rivers will be of value to students and specialist researchers alike, as well as to those with a more general interest in aquatic ecology, polar environments or global change who require an authoritative overview of this fast emerging topic.

DOWNLOAD EBOOK →In this edition of the Long Term Ecological Research Network series, editors John Hobbie and George Kling and 58 co-authors synthesize the findings from the NSF-funded Arctic LTER project based at Toolik Lake, Alaska, a site that has been active since the mid-1970s. The book presents research on the core issues of climate-change science in the treeless arctic region of Alaska. As a whole, it examines both terrestrial and freshwater-aquatic ecosystems, and their three typical habitats: tundra, streams, and lakes. The book provides a history of the Toolik Lake LTER site, and discusses its present condition and future outlook. It features contributions from top scientists from many fields, creating a multidisciplinary survey of the Alaskan arctic ecosystem. Chapter topics include glacial history, climatology, land-water interactions, mercury found in the Alaskan arctic, and the response of these habitats to environmental change. The final chapter predicts the consequences that arctic Alaska faces due to global warming and climate change, and discusses the future ecology of the LTER site in the region. Alaska's Changing Arctic is the definitive scientific survey of the past, present, and future of the ecology of the Alaskan arctic.

DOWNLOAD EBOOK →The SAGE Handbook of Environmental Change is an extensive survey of the interdisciplinary science of environmental change, including recent debates on climate change and the full range of other natural and anthropogenic changes affecting the Earth-ocean-atmosphere system in the past, present and future. It examines the historic importance, present status and future prospects of the field over two volumes. With more than 40 chapters, the books situate the defining characteristics and key paradigms within a state-of-the-art review of the field, including its changing nature and diversity of approaches, evidence base, key theoretical arguments, resonances with other disciplines and relationships between theory, research and practice. Opening with a detailed, contextualizing essay by the editors, the work is arranged into six parts: Part One: Approaches to Understanding Environmental Change Part Two: Evidence of Environmental Change and the Geo-ecological Response Part Three: Causes, Mechanisms and Dynamics of Environmental Change Part Four: Key Issues of Human-induced Environmental Changes and Their Impacts Part Five: Patterns, Processes and Impacts of Environmental Change at the Regional Scale Part Six: Responses of People to Environmental Change and Implications for Society Global in its coverage, scientific and theoretical in its approach, the books bring together an international set of respected editors and contributors to provide an exciting, timely addition to the literature on climate change. With the subjects′ interdisciplinary framework, this book will appeal to academics, researchers, postgraduates and practitioners in a variety of disciplines including, geography, geology, ecology, environmental science, archaeology, anthropology, politics and sociology.

DOWNLOAD EBOOK →Antarctica is renowned for its extreme cold; yet surprisingly, radar measurements have revealed a vast network of lakes, rivers, and streams several kilometers beneath the Antarctic ice sheet. Sealed from Earth's atmosphere for millions of years, they may provide vital information about microbial evolution, the past climate of the Antarctic, and the formation of ice sheets, among other things. The next stage of exploration requires direct sampling of these aquatic systems. However, if sampling is not done cautiously, the environmental integrity and scientific value of these environments could be compromised. At the request of the National Science Foundation, this National Research Council assesses what is needed to responsibly explore subglacial lakes. Exploration of Antarctic Subglacial Aquatic Environments concludes that it is time for research on subglacial lakes to begin, and this research should be guided by internationally agreed upon protocols. The book suggests an initial protocol, which includes full characterization of the lakes by remote sensing, and minimum standards for biological and other types of contamination.

DOWNLOAD EBOOK →In 2007-2008, many nations around the world will host an intense, coordinated field campaign of polar observations, research, and analysis called the "International Polar Year." This report presents an overview of potential science themes, enabling technologies, and public outreach opportunities that can be used to focus International Polar Year on societal needs. The committee recommends that the U.S. scientific community and participating agencies use this opportunity to better understand environmental change and variability in the polar regions; explore new scientific frontiers ranging from the molecular to the planetary scales; and engage the public through varied educations and outreach activities.
