Book Description
Fossilized dinosaur bones. Caribou tracks, both ancient and new. Wide open spaces. Vast migrations... The National Petroleum Reserve -- Alaska is more than a natural resource -- it's a place of rare, unprotected beauty * Full color conservation advocacy book features essays from Arctic authorities such as Bruce Babbitt, Jack Horner, Jeff Fair, and more. * Published in collaboration with the Alaska Wilderness League Originally set aside by President Harding in 1923 as a back-up resource for military fuel needs, the National Petroleum Reserve -- Alaska is home to half a million migrating caribou, countless migrating birds from all over the world, and, surprisingly, one of the largest Polar dinosaur fossil beds in the Arctic. The Reserve is also the largest piece of undisturbed public land in the United States -- yet few outside of Alaska have ever heard of it. On Arctic Ground, from Braided River, the conservation imprint of Mountaineers Books, features a series of vignettes written by well-loved Alaskan author Debbie S. Miller (Midnight Wilderness) about the astonishing array of wildlife she has encountered over many seasons exploring the Reserve. Additionally, former Secretary of the Interior Bruce Babbitt writes the book's preface, drawing on his years of experience managing both the economic and biological resources of the Reserve. Miller's vignettes are accompanied by images from an array of award-winning conservation photographers. The book also features essays and insight from Alaskan writers and science authorities -- including wildlife biologist Jeff Fair and senior Audubon Alaska scientist John Schoen -- as well as an essay and audio download by noted Alaska writer and soundscape artist Richard Nelson. Paleontologists Jack Horner and Patrick Druckenmiller share the most recent research and remarkable discoveries associated with dinosaur studies in the Alaskan Arctic. This book will serve as a platform to bring greater public awareness to the opportunities for permanently preserving the significant biological areas and wildlife that thrive within the Reserve. Braided River will collaborate with the Alaska Wilderness League to bring this story to members of Congress, the media, and the general public. Visit www.braidedriver.org to learn more.

Book Description
The Arctic, long described as the world’s last frontier, is quickly becoming our first frontier—the front line in a world of more diffuse power, sharper geopolitical competition, and deepening interdependencies between people and nature. A space of often-bitter cold, the Arctic is the fastest-warming place on earth. It is humanity’s canary in the coal mine—an early warning sign of the world’s climate crisis. The Arctic “regime” has pioneered many innovative means of governance among often-contentious state and non-state actors. Instead of being the “last white dot on the map,” the Arctic is where the contours of our rapidly evolving world may first be glimpsed. In this book, scholars and practitioners—from Anchorage to Moscow, from Nuuk to Hong Kong—explore the huge political, legal, social, economic, geostrategic and environmental challenges confronting the Arctic regime, and what this means for the future of world order.

Book Description
In one hundred years, or even fifty, the Arctic will look dramatically different than it does today. As polar ice retreats and animals and plants migrate northward, the arctic landscape is morphing into something new and very different from what it once was. While these changes may seem remote, they will have a profound impact on a host of global issues, from international politics to animal migrations. In Future Arctic, journalist and explorer Edward Struzik offers a clear-eyed look at the rapidly shifting dynamics in the Arctic region, a harbinger of changes that will reverberate throughout our entire world. Future Arctic reveals the inside story of how politics and climate change are altering the polar world in a way that will have profound effects on economics, culture, and the environment as we know it. Struzik takes readers up mountains and cliffs, and along for the ride on snowmobiles and helicopters, sailboats and icebreakers. His travel companions, from wildlife scientists to military strategists to indigenous peoples, share diverse insights into the science, culture and geopolitical tensions of this captivating place. With their help, Struzik begins piecing together an environmental puzzle: How might the land’s most iconic species—caribou, polar bears, narwhal—survive? Where will migrating birds flock to? How will ocean currents shift? And what fundamental changes will oil and gas exploration have on economies and ecosystems? How will vast unclaimed regions of the Arctic be divided? A unique combination of extensive on-the-ground research, compelling storytelling, and policy analysis, Future Arctic offers a new look at the changes occurring in this remote, mysterious region and their far-reaching effects.

Book Description
Most of the Earth’s biosphere is characterized by low temperatures. Vast areas (>20%) of the soil ecosystem are permanently frozen or are unfrozen for only a few weeks in summer. Permafrost regions occur at high latitudes and also at high ele- tions; a significant part of the global permafrost area is represented by mountains. Permafrost soils are of global interest, since a significant increase in temperature is predicted for polar regions. Global warming will have a great impact on these soils, especially in northern regions, since they contain large amounts of organic carbon and act as carbon sinks, and a temperature increase will result in a release of carbon into the atmosphere. Additionally, the intensified release of the clima- relevant tracer gas methane represents a potential environmental harzard. Significant numbers of viable microorganisms, including bacteria, archaea, p- totrophic cyanobacteria and green algae, fungi and protozoa, are present in per- frost, and the characteristics of these microorganisms reflect the unique and extreme conditions of the permafrost environment. Remarkably, these microorg- isms have been reported to be metabolically active at subzero temperatures, even down to ?20°C.

Book Description
The Arctic is home to animals that have taken adaptations to overwintering to extremes. In this dissertation, I have investigated one of these adaptations, hibernation, in two species from the Arctic, the Alaska marmot (Marmota broweri) and the arctic ground squirrel (Urocitellus parryii). The expression of hibernation under natural conditions in these species was compared by collecting body temperature records of free-living individuals. The Alaska marmot, a highly social species, demonstrated extreme synchrony in body temperature patterns among a family group, indicating a strong reliance on social thermoregulation. In contrast, the arctic ground squirrel was confirmed to be a solitary hibernator that reduces body temperature below freezing during torpor. Both species must produce heat when soil temperatures are significantly below freezing for most of the winter. At these subfreezing ambient temperatures, the arctic ground squirrel has shown an increasing reliance on nonlipid fuel during torpor, driving a loss of lean mass during hibernation of ~20%. I calibrated deuterium dilution to repeatedly estimate body composition in this species, which dramatically changes adiposity through its annual cycle, and used this technique to quantify lean mass loss throughout hibernation in a study of tissue metabolism. I also developed and applied the natural abundance of nitrogen and carbon stable isotopes as tools for monitoring differential tissue metabolism and differentiating mixed metabolic fuel use in the arctic ground squirrel. These data clarified the mechanism of change in nitrogen stable isotopes andd, indicated that hibernating ground squirrels rebuild organ tissues while breaking down muscle tissue to meet energetic demands. Furthermore, I corroborated a shift in metabolic fuel use toward nonlipid sources during torpor at low ambient temperatures by using the carbon isotope ratio in exhaled breath in combination with respiratory quotient. This dissertation combines studies of hibernation patterns in free-living animals with experimental data on the tissues and fuels being catabolized at very low temperatures to broaden our understanding of how small mammals successfully hibernate in severe winter conditions. It also presents the development and use of stable isotope ratios as physiological tools in hibernating species.

Book Description
Viewed in satellite images as a jagged white coat draped over the top of the globe, the high Arctic appears distant and isolated. But even if you don't live there, don't do business there, and will never travel there, you are closer to the Arctic than you think. Arctic Matters: The Global Connection to Changes in the Arctic is a new educational resource produced by the Polar Research Board of the National Research Council (NRC). It draws upon a large collection of peer-reviewed NRC reports and other national and international reports to provide a brief, reader-friendly primer on the complex ways in which the changes currently affecting the Arctic and its diverse people, resources, and environment can, in turn, affect the entire globe. Topics in the booklet include how climate changes currently underway in the Arctic are a driver for global sea-level rise, offer new prospects for natural resource extraction, and have rippling effects through the world's weather, climate, food supply and economy.
