A must-read about these magnificent but sometimes deadly creatures—thoroughly revised, expanded, and updated

    In what has become one of science's greatest riddles, these large animals vanished in North and South America around the time humans arrived at the end of the last great ice age. Part paleontological adventure and part memoir, Twilight of the Mammoths presents in detail internationally renowned paleoecologist Paul Martin's widely discussed and debated "overkill" hypothesis to explain these mysterious megafauna extinctions. Taking us from Rampart Cave in the Grand Canyon, where he finds himself "chest deep in sloth dung," to other important fossil sites in Arizona and Chile, Martin's engaging book, written for a wide audience, uncovers our rich evolutionary legacy and shows why he has come to believe that the earliest Americans literally hunted these animals to death.As he discusses the discoveries that brought him to this hypothesis, Martin relates many colorful stories and gives a rich overview of the field of paleontology as well as his own fascinating career. He explores the ramifications of the overkill hypothesis for similar extinctions worldwide and examines other explanations for the extinctions, including climate change. Martin's visionary thinking about our missing megafauna offers inspiration and a challenge for today's conservation efforts as he speculates on what we might do to remedy this situation—both in our thinking about what is "natural" and in the natural world itself.

    The roots of a tree indicate the sun’s direction; the Big Dipper tells the time; a passing butterfly hints at the weather; a sand dune reveals prevailing wind; the scent of cinnamon suggests altitude; a budding flower points south.

    Humans have feared them for centuries, long considering them the assassins and pariahs of the natural world.Now, in Venomous, the biologist Christie Wilcox investigates and illuminates the animals of our nightmares, arguing that they hold the keys to a deeper understanding of evolution, adaptation, and immunity. She reveals just how venoms function and what they do to the human body. With Wilcox as our guide, we encounter a jellyfish with tentacles covered in stinging cells that can kill humans in minutes; a two-inch caterpillar with toxic bristles that trigger hemorrhaging; and a stunning blue-ringed octopus capable of inducing total paralysis. How do these animals go about their deadly work? How did they develop such intricate, potent toxins? Wilcox takes us around the world and down to the cellular level to find out.Throughout her journey, Wilcox meets the intrepid scientists who risk their lives studying these lethal beasts, as well as “self-immunizers” who deliberately expose themselves to snakebites. Along the way, she puts her own life on the line, narrowly avoiding being envenomated herself. Drawing on her own research, Wilcox explains how venom scientists are untangling the mechanisms of some of our most devastating diseases, and reports on pharmacologists who are already exploiting venoms to produce lifesaving drugs. We discover that venomous creatures are in fact keystone species that play crucial roles in their ecosystems and ours—and for this alone, they ought to be protected and appreciated.Thrilling and surprising at every turn, Venomous will change everything you thought you knew about the planet’s most dangerous animals.

    This is the chilling story of a two-year-long investigation into a dangerous criminal underworld and the merciless syndicates that will stop at nothing to obtain their prize. It is a tale of greed, folly and corruption, and of an increasingly desperate battle to save the rhino - which has existed for more than 50 million years - from extinction.Killing for Profit is a meticulous, devastating and revelatory account of one of the world’s most secretive trades. It exposes poachers, scoundrels, gangsters, conmen, mercenaries, killers, gun-runners, diplomats, government officials and kingpins behind the slaughter. And it follows the bloody trail from the frontlines of the rhino wars in south Africa, Zimbabwe and Mozambique to the medicine markets of Vietnam and the lair of a wildlife-trafficking kingpin on the banks of the Mekong River in Laos …

    All of them - hikers, hunters, fishermen, campers, and canoeists - are drawn to the woods for some special reason. Yet few of them see the forest as a whole, as the web of life it truly is. Here, from New York Times bestselling author Richard M. Ketchum, is the extraordinary story of forests and the trees that comprise them.

    But even residents on this idyllic California coast may not realize its full history. Monterey began as a natural paradise, but became the poster child for industrial devastation in John Steinbeck’s Cannery Row,and is now one of the most celebrated shorelines in the world.   It is a remarkable story of life, death, and revival—told here for the first time in all its stunning color and bleak grays. The Death and Life of Monterey Bay begins in the eighteenth century when Spanish and French explorers encountered a rocky shoreline brimming with life—raucous sea birds, abundant sea otters, barking sea lions, halibut the size of wagon wheels,waters thick with whales. A century and a half later, many of the sea creatures had disappeared, replaced by sardine canneries that sickened residents with their stench but kept the money flowing. When the fish ran out and the climate turned,the factories emptied and the community crumbled. But today,both Monterey’s economy and wildlife are resplendent. How did it happen?   The answer is deceptively simple: through the extraordinary acts of ordinary people. The Death and Life of Monterey Bay is the biography of a place, but also of the residents who reclaimed it. Monterey is thriving because of an eccentric mayor who wasn’t afraid to use pistols, axes, or the force of law to protect her coasts. It is because of fishermen who love their livelihood, scientists who are fascinated by the sea’s mysteries, and philanthropists and community leaders willing to invest in a world-class aquarium. The shores of Monterey Bay revived because of human passion—passion that enlivens every page of this hopeful book.

    . . a fascinating tome.” —Huffington Post A visual trove of more than 300 dinosaurs, with key anatomy, geology, history, and theory at a glance We live in a golden age of paleontological discovery—the perfect time to dig in to the spectacular world of dinosaurs. From Aardonyx, a lumbering beast that formed a link between two- and four-legged dinosaurs, to Zuniceratops, who boasted a deadly pair of horns, Dinosaurs—The Grand Tour details everything worth knowing about more than 300 dinosaurs. The important discoveries and gory details touch on topics from geology, anatomy, and evolution to astronomy and even Native American and Chinese myth. Fascinating facts abound: Giganotosaurus was longer, two tons heavier, and had bigger jaws than T. Rex. The poison-spitting Dilophosaurus from Jurassic Park wasn’t actually venomous at all.?? Because of its bizarre single-clawed hands, scientists now believe Mononykus was a prehistoric predecessor of the anteater! Illustrations on virtually every page, true to the latest findings, bring these prehistoric creatures to life in all their razor-sharp, long-necked, spiny, scaly glory.

    News of both the Ice Man's discovery and his age, which was put at over five thousand years, fascinated scientists and newspapers throughout the world. But what made Sykes's story particularly revelatory was his successful identification of a genetic descendant of the Ice Man, a woman living in Great Britain today. How was Sykes able to locate a living relative of a man who died thousands of years ago?In The Seven Daughters of Eve, he gives us a firsthand account of his research into a remarkable gene, which passes undiluted from generation to generation through the maternal line. After plotting thousands of DNA sequences from all over the world, Sykes found that they clustered around a handful of distinct groups. Among Europeans and North American Caucasians, there are, in fact, only seven. This conclusion was staggering: almost everyone of native European descent, wherever they may live throughout the world, can trace their ancestry back to one of seven women, the Seven Daughters of Eve.Naming them Ursula, Xenia, Helena, Velda, Tara, Katrine, and Jasmine, Sykes has created portraits of their disparate worlds by mapping the migratory patterns followed by millions of their ancestors. In reading the stories of these seven women, we learn exactly how our origins can be traced, how and where our ancient genetic ancestors lived, and how we are each living proof of the almost indestructible strands of DNA, which have survived over so many thousands of years. Indeed, The Seven Daughters of Eve is filled with dramatic stories: from Sykes's identification, using DNA samples from two living relatives, of the remains of Tsar Nicholas and Tsaress Alexandra, to the Caribbean woman whose family had been sold into slavery centuries before and whose ancestry Sykes was able to trace back to the Eastern coast of central Africa. Ultimately, Sykes's investigation reveals that, as a race, what humans have in common is more deeply embedded than what separates us.

    Accompanying every species entry is a distribution map and illustrations showing the species in all the major plumages (male, female, immature, in flight, at rest, feeding: whatever is important).In addition, each group of birds includes an introduction which covers the major problems involved in identifying or observing them: how to organise a sea watching trip, how to separate birds of prey in flight, which duck hybrids can be confused with which main species. These and many other common birdwatching questions are answered.The combination of definitive text, up-to-date distribution maps and superb illustrations, all in a single volume, makes this book the ultimate field guide, essential on every bookshelf and birdwatching trip.
