Weaving together the cosmos' history and our own in an expanding intellectual adventure story, Dark Matter and the Dinosaurs takes us from the mysteries of dark matter and our cosmic environment to the conditions for life on Earth.Sixty-six million years ago, an object the size of a city descended from space to crash into Earth, creating a cataclysm that killed off the dinosaurs, along with three-quarters of the other species on the planet. What was its origin? Randall proposes it was a comet that was dislodged from its orbit as the Solar System passed through a disk of dark matter that is embedded in the plane of the Milky Way. Her research challenges the usual assumptions about the simple nature of dark matter and demonstrates how scientists formulate and establish new ideas. In a sense, it might have been dark matter that killed the dinosaurs.With her unique and wide-ranging perspective, Randall connects dark matter to the history of the world in the broadest terms. Bringing in pop culture and social and political viewpoints, she shares with us the latest findings—established and speculative—regarding dark matter, the cosmos, the galaxy, asteroids, comets, and impacts, as well as life's development and extinctions. Randall makes clear how connected the planet is to the makeup of the Universe, but also how fragile our place in the Universe, which evolved over billions of years, might be.In this brilliant and fresh exploration of our cosmic environment, Professor Randall explains the underlying science of our world in the breathtaking tale of a Universe in which the small and the large, the visible and the hidden are intimately related. Dark Matter and the Dinosaurs illuminates the deep relationships that are critical to our world as well as the astonishing beauty of the structures and connections that surround us. It's impossible to read this book and look at either Earth or sky again in the same way.

    They traveled from Newfoundland to Florida, deep into the heart of Mexico, through the Southwest, the Pacific Northwest, and into Alaska's Pribilof Islands. Two years later, Wild America, their classic account of the trip, was published.On the eve of that book's fiftieth anniversary, naturalist Scott Weidensaul retraces Peterson and Fisher's steps to tell the story of wild America today. How has the continent's natural landscape changed over the past fifty years? How have the wildlife, the rivers, and the rugged, untouched terrain fared? The journey takes Weidensaul to the coastal communities of Newfoundland, where he examines the devastating impact of the Atlantic cod fishery's collapse on the ecosystem; to Florida, where he charts the virtual extinction of the great wading bird colonies that Peterson and Fisher once documented; to the Mexican tropics of Xilitla, which have become a growing center of ecotourism since Fisher and Peterson's exposition. And perhaps most surprising of all, Weidensaul finds that much of what Peterson and Fisher discovered remains untouched by the industrial developments of the last fifty years. Poised to become a classic in its own right, Return to Wild America is a sweeping survey of the natural soul of North America today.

    It dispels common misconceptions about flies and reveals how truly extraordinary, exotic and important are these misunderstood creatures.There are ten chapters:1. The immature ones - Squirmy wormy larvae can be just a bit unnerving, especially when they're in large numbers.2. The pollinators - Those annoying No See Ums, or midge flies, are the only pollinator of the chocolate-producing cacao tree, a status held by many of the pollinators.3. The detritivores - These garbage eaters are often fluffy and thus water-repellent, good for a life spent in a sewer.4. The vegetarians - Entomological spelunkers, many of these flies prefer plant roots forsaking the leaves to other creatures.5. The fungivores - The mushroom eaters include the dark-winged fungus gnats whose wing patterns are one of the author's favorites.6. The predators - Here are the most devious and imaginative methods of luring, capturing and eating prey.7. The parasites - Their methods of survival are often disgusting but the evolutionary genius is admirable.8. The sanguivores - McAlister responds to the perpetual question, exactly why do we have blood-sucking disease-spreading mosquitos?9. The coprophages - The champions of dung, detritus and other unpleasant things.10. The necrophages - The body eaters without which we would be in a most disagreeable situation.In clear language, McAlister explains Diptera taxonomy and forensic entomology, and describes the potential of flies to transform their relationship with humans from one of disease vector to partner in environmental preservation. She has a wonderful knack for storytelling, deftly transforming what could be dry descriptions of biology, reproduction and morphology into entertainment. She takes readers to piles of poo in Ethiopia by way of underground caves, latrines and backyard gardens, and opens the drawers at the Natural History Museum to rhapsodize over her favorite flies.The Secret Life of Flies is full of stories and tongue-in-check descriptions, but the science is rigorous, authoritative and will be enjoyed by dipterists, lepidopterists, insect enthusiasts, naturalists, and general readers.

    For three men in particular, 1998 would become a grueling battle for a new North American birding record. Bouncing from coast to coast on frenetic pilgrimages for once-in-a-lifetime rarities, they brave broiling deserts, bug-infested swamps, and some of the lumpiest motel mattresses known to man. This unprecedented year of beat-the-clock adventures ultimately leads one man to a record so gigantic that it is unlikely ever to be bested. Here, prize-winning journalist Mark Obmascik creates a dazzling, fun narrative of the 275,000-mile odyssey of these three obsessives as they fight to win the greatest -- or maybe worst -- birding contest of all time.

    As the forerunner of such important books as Annie Dillard's Pilgrim at Tinker Creek, Edward Abbey's Desert Solitaire, and Robert Finch's The Primal Place, this classic work remains as relevant today as it was sixty-five years ago.

    bataar bones he was impressed. The enormous skull and teeth betrayed the apex predators close relation to the storied Tyrannosaurus rex, the most famous animal that ever lived. Prokopi's obsession with fossils had begun decades earlier, when he was a Florida boy scouring for shark teeth and Ice Age remnants, and it had continued as he built a thriving business hunting, preparing, and selling specimens to avid collectors and private museums around the world. To scientists' fury and dismay, there was big money to be made in certain corners of the fossil trade. Prokopi didn't consider himself merely a businessman, though. He also thought of himself as a vital part of paleontology--as one of the lesser-known artistic links in bringing prehistoric creatures back to life--and saw nothing wrong with turning a profit in the process. Bone hunting was expensive, risky, controversial work, and he increasingly needed bigger "scores." By the time he acquired a largely complete skeleton of T. bataar and restored it in his workshop, he was highly leveraged and drawing quiet scorn from peers who worried that by bringing such a big, beautiful Mongolian dinosaur to market he would tarnish the entire trade. Presenting the skeleton for sale at a major auction house in New York City, he was relieved to see the bidding start at nearly $1 million---only to fall apart when the president of Mongolia unexpectedly stepped in to question the specimen's origins and demand its return. An international custody battle ensued, shining new light on the black market for dinosaur fossils, the angst of scientists who fear for their field, and the precarious political tensions in post-Communist Mongolia. The Prokopi case, unprecedented in American jurisprudence, continues to reverberate throughout the intersecting worlds of paleontology, museums, art, and geopolitics.

    In July he finds it while taking a dip in a 35-degree Arctic swimming hole; in September while excavating our planet's ancient and not so ancient ice ages; and in October while exploring hibernation habits in animals, from humans to wood frogs to bears.A scientist whose passion for cold runs red hot, Streever is a wondrous guide: he conjures woolly mammoth carcasses and the ice-age Clovis tribe from melting glaciers, and he evokes blizzards so wild readers may freeze--limb by vicarious limb.

Insectopedia shows us how insects have triggered our obsessions, stirred our passions, and beguiled our imaginations.From the Trade Paperback edition.

    

    A week later, Lincoln Hall, a seasoned Australian climber, was left for dead near the same spot. Hall's death was reported around the world, but the next day he was found alive after spending the night on the upper mountain with no food and no shelter.If David Sharp's death was shocking, it was hardly singular: despite unusually good weather, ten others died attempting to reach the summit that year. In this meticulous inquiry into what went wrong, Nick Heil tells the full story of the deadliest year on Everest since the infamous season of 1996. He introduces Russell Brice, the commercial operator who has done more than anyone to provide access to the summit via the mountain's north side—and who some believe was partly accountable for Sharp's death. As more climbers attempt the summit each year, Heil shows how increasingly risky expeditions and unscrupulous outfitters threaten to turn Everest into a deadly circus.Written by an experienced climber and outdoor writer, Dark Summit is both a riveting account of a notorious climbing season and a troubling investigation into whether the pursuit of the ultimate mountaineering prize has spiraled out of control.
