Only a few species of wild animals can survive its harsh climate. In this modern classic, Barry Lopez explores the many-faceted wonders of the Far North: its strangely stunted forest, its mesmerizing aurora borealis, its frozen seas. Musk oxen, polar bears, narwhal, and other exotic beasts of the region come alive through Lopez’s passionate and nuanced observations. And, as he examines the history and culture of the indigenous people, along with parallel narratives of intrepid, often underprepared and subsequently doomed polar explorers, Lopez drives to the heart of why the austere and formidable Arctic is also a constant source of breathtaking beauty, beguilement, and wonder.Written in prose as memorably pure as the land it describes, Arctic Dreams is a timeless mediation on the ability of the landscape to shape our dreams and to haunt our imaginations.

    Far less well-known is a much greater catastrophe that took place at the end of the Permian period 251 million years ago: 90 percent of life was destroyed, including saber-toothed reptiles and their rhinoceros-sized prey on land, as well as vast numbers of fish and other species in the sea.This book documents not only what happened during this gigantic mass extinction but also the recent rekindling of the idea of catastrophism. Was the end-Permian event caused by the impact of a huge meteorite or comet, or by prolonged volcanic eruption in Siberia? The evidence has been accumulating through the 1990s and into the new millennium, and Michael Benton gives his verdict at the very end. From field camps in Greenland and Russia to the laboratory bench, When Life Nearly Died involves geologists, paleontologists, environmental modelers, geochemists, astronomers, and experts on biodiversity and conservation. Their working methods are vividly described and explained, and the current disputes are revealed. The implications of our understanding of crises in the past for the current biodiversity crisis are also presented in detail. 46 b/w illustrations.

    But we long to know more: how did these animals actually behave? We are fascinated by the daily lives of our fellow creatures--how they reproduce and raise their young, how they hunt their prey or elude their predators, and more. What would it be like to see prehistoric animals as they lived and breathed?From dinosaurs fighting to their deaths to elephant-sized burrowing ground sloths, this book takes readers on a global journey deep into the earth's past. Locked in Time showcases fifty of the most astonishing fossils ever found, brought together in five fascinating chapters that offer an unprecedented glimpse at the real-life behaviors of prehistoric animals. Dean R. Lomax examines the extraordinary direct evidence of fossils captured in the midst of everyday action, such as dinosaurs sitting on their eggs like birds, Jurassic flies preserved while mating, a T. rex infected by parasites. Each fossil, he reveals, tells a unique story about prehistoric life. Many recall behaviors typical of animals familiar to us today, evoking the chain of evolution that links all living things to their distant ancestors. Locked in Time allows us to see that fossils are not just inanimate objects: they can record the life stories of creatures as fully alive as any today. Striking and scientifically rigorous illustrations by renowned paleoartist Bob Nicholls bring these breathtaking moments to life.

    Even now, the vast majority of this wilderness - which covers over 70% of the planet and forms its largest ecosystem - has never been seen by human eyes, let alone explored or investigated by scientists. Yet our oceans contain perhaps 90% of all life, and the physical and biological processes within it are critical to supporting our existence on Earth.Professor Alex Rogers has spent the past 30 years studying life in the deep ocean. In this book, he takes us on an epic and utterly unforgettable voyage to an alien world, and brings us right to the edge of what is known about our oceans today. Introducing us to glittering coral gardens, submarine mountains and a range of bizarre and breathtaking sea creatures, many of which he discovered first-hand, Rogers not only illustrates the ocean's enormous and untold impact on our lives, but also shows how we are damaging it catastrophically through pollution, overfishing, and the insidious and global effects of climate change.Imbued with the author's infectious sense of wonder, and replete with stunning photography of underwater life, The Deep is a magisterial study of a world we are only just beginning to understand - and a profoundly hopeful call to arms for us to reshape our relationship with it, before it is too late.

    They made the world theirs long before the rise of dinosaurs. Travelling forward into the Permian and then Triassic periods, we learn how our ancient mammal ancestors evolved from large hairy beasts with accelerating metabolisms to exploit miniaturisation, which was key to unlocking the traits that define mammals as we now know them. Elsa criss-crosses the globe to explore the sites where discoveries are being made and meet the people who make them. In Scotland, she traverses the desert dunes of prehistoric Moray, where quarry workers unearthed the footprints of Permian creatures from before the time of dinosaurs. In South Africa, she introduces us to animals, once called 'mammal-like reptiles', that gave scientists the first hints that our furry kin evolved from a lineage of egg-laying burrowers. In China, new, complete fossilised skeletons reveal mammals that were gliders, shovel-pawed Jurassic moles, and flat-tailed swimmers.This book radically reframes the narrative of our mammalian ancestors and provides a counterpoint to the stereotypes of mighty dinosaur overlords and cowering little mammals. It turns out the earliest mammals weren't just precursors, they were pioneers.

    After World War II, it reshaped the global order-whoever could master uranium could master the world. Marie Curie gave us hope that uranium would be a miracle panacea, but the Manhattan Project gave us reason to believe that civilization would end with apocalypse. Slave labor camps in Africa and Eastern Europe were built around mine shafts and America would knowingly send more than six hundred uranium miners to their graves in the name of national security. Fortunes have been made from this yellow dirt; massive energy grids have been run from it. Fear of it panicked the American people into supporting a questionable war with Iraq and its specter threatens to create another conflict in Iran. Now, some are hoping it can help avoid a global warming catastrophe. In "Uranium," Tom Zoellner takes readers around the globe in this intriguing look at the mineral that can sustain life or destroy it.

    

    What we’ve learned of these key migrations—how billions of birds circumnavigate the globe, flying tens of thousands of miles between hemispheres on an annual basis—is nothing short of extraordinary.Bird migration entails almost unfathomable endurance, like a sparrow-sized sandpiper that will fly nonstop from Canada to Venezuela—the equivalent of running 126 consecutive marathons without food, water, or rest—avoiding dehydration by "drinking" moisture from its own muscles and organs, while orienting itself using the earth’s magnetic field through a form of quantum entanglement that made Einstein queasy. Crossing the Pacific Ocean in nine days of nonstop flight, as some birds do, leaves little time for sleep, but migrants can put half their brains to sleep for a few seconds at a time, alternating sides—and their reaction time actually improves.These and other revelations convey both the wonder of bird migration and its global sweep, from the mudflats of the Yellow Sea in China to the remote mountains of northeastern India to the dusty hills of southern Cyprus. This breathtaking work of nature writing from Pulitzer Prize finalist Scott Weidensaul also introduces readers to those scientists, researchers, and bird lovers trying to preserve global migratory patterns in the face of climate change and other environmental challenges.Drawing on his own extensive fieldwork, in A World on the Wing Weidensaul unveils with dazzling prose the miracle of nature taking place over our heads.

    His genius as an essayist lies in his unmatched ability to use his knowledge of the world, including popular culture, to illuminate the realm of science.Ever Since Darwin, Stephen Jay Gould's first book, has sold more than a quarter of a million copies. Like all succeeding collections by this unique writer, it brings the art of the scientific essay to unparalleled heights.

    In the process, the abyss is being revealed as perhaps the most amazing part of our planet, its topography even more varied and extreme than its landmass counterpart.Teeming with unsuspected life, an extraordinary, interconnected ecosystem deep below the waves has a huge effect on our daily lives, influencing climate and weather systems, with the potential for much more--good or bad, depending on how it is exploited. Currently, the fantastic creatures that live in the deep--many of them incandescent in a world without light--and its formations capture and trap vast quantities of carbon that would otherwise poison our atmosphere, and novel bacteria as yet undiscovered hold the promise of potent new medicines. Yet the deep also holds huge mineral riches lusted after by nations and corporations; mining them could ultimately devastate the planet, compounded by the deepening impacts of ubiquitous pollutants and rampant overfishing.Eloquently and passionately, the author of Spirals in Time and Eye of the Shoal brings to life the majesty and mystery of an alien realm that nonetheless sustains us, while urgently making clear the price we could pay if it is further disrupted. The Brilliant Abyss is at once a revelation and a clarion call to preserve this vast unseen world.

    But they are relative newcomers there. They evolved in North America and retain their greatest diversity in South America, while the only wild dromedaries are in Australia.This is a classic example of the contradictions of 'native' and 'invasive' species, a hot issue right now as the flip-side of biodiversity. Do we need to fear invaders? Can we control them? Do we choose the right targets? And are the natives always good guys?Thompson puts forward a fascinating array of narratives to explore this crucial question.
