The consequences of losing beavers were profound: streams eroded, wetlands dried up, and species from salmon to swans lost vital habitat. Today, a growing coalition of “Beaver Believers”―including scientists, ranchers, and passionate citizens―recognizes that ecosystems with beavers are far healthier, for humans and non-humans alike, than those without them. From the Nevada deserts to the Scottish highlands, Believers are now hard at work restoring these industrious rodents to their former haunts. Eager is a powerful story about one of the world’s most influential species, how North America was colonized, how our landscapes have changed over the centuries, and how beavers can help us fight drought, flooding, wildfire, extinction, and the ravages of climate change. Ultimately, it’s about how we can learn to coexist, harmoniously and even beneficially, with our fellow travelers on this planet.

    Breaking down the symbols themselves, they pose a series of questions: What is energy? What is mass? What has the speed of light got to do with energy and mass? In answering these questions, they take us to the site of one of the largest scientific experiments ever conducted. Lying beneath the city of Geneva, straddling the Franco-Swiss boarder, is a 27 km particle accelerator, known as the Large Hadron Collider. Using this gigantic machine—which can recreate conditions in the early Universe fractions of a second after the Big Bang—Cox and Forshaw will describe the current theory behind the origin of mass.Alongside questions of energy and mass, they will consider the third, and perhaps, most intriguing element of the equation: 'c' - or the speed of light. Why is it that the speed of light is the exchange rate? Answering this question is at the heart of the investigation as the authors demonstrate how, in order to truly understand why E=mc2, we first must understand why we must move forward in time and not backwards and how objects in our 3-dimensional world actually move in 4-dimensional space-time. In other words, how the very fabric of our world is constructed. A collaboration between two of the youngest professors in the UK, Why Does E=mc2? promises to be one of the most exciting and accessible explanations of the theory of relativity in recent years.

    Across North America, tens of thousands of people gather every spring and fall at more than one thousand known hawk migration sites--from New Jersey's Cape May to California's Golden Gate. Yet, as many discover, a standard field guide, with its emphasis on plumage, is often of little help in identifying those raptors soaring, gliding, or flapping far, far away.Hawks from Every Angle takes hawk identification to new heights. It offers a fresh approach that literally looks at the birds from every angle, compares and contrasts deceptively similar species, and provides the pictures (and words) needed for identification in the field. Jerry Liguori pinpoints innovative, field-tested identification traits for each species from the various angles that they are seen.Featuring 339 striking color photos on 68 color plates and 32 black & white photos, Hawks from Every Angle is unique in presenting a host of meticulously crafted pictures for each of the 19 species it covers in detail--the species most common to migration sites throughout the United States and Canada. All aspects of raptor identification are discussed, including plumage, shape, and flight style traits.For all birders who follow hawk migration and have found themselves wondering if the raptor in the sky matches the one in the guide, Hawks from Every Angle--distilling an expert's years of experience for the first time into a comprehensive array of truly useful photos and other pointers for each species--is quite simply a must.Key Features? The essential new approach to identifying hawks in flight Innovative, accurate, and field-tested identification traits for each species 339 color photos on 68 color plates, 32 black & white photos Compares and contrasts species easily confused with one another, and provides the pictures (and words) needed for identification in the field Covers in detail 19 species common to migration sites throughout the North America Discusses light conditions, how molt can alter the shape of a bird, aberrant plumages, and migration seasons and sites User-friendly format

    Photographer Glen Denny was a key figure in this golden age of climbing, capturing pioneering feats on camera while tackling challenging ascents himself.In entertaining short pieces enlivened by his iconic black-and-white images of Yosemite's big wall legends, Denny reveals a young man's coming of age and provides a vivid look at Yosemite’s early climbing culture. He relates such precarious achievements as hauling water in glass gallon jugs up the east face of Washington Column, nailing the 750-foot Rostrum in a punishing heat wave, and dangling overnight on El Capitan’s Dihedral Wall in a lightning storm. Each true tale captures the spirit of historic Camp 4, where Denny and others plan the next big climb while living on the cheap and dodging park rangers.

    . . a book that enriches our understanding of how the struggle to think new thoughts is shared across time and space and people.”—The Sunday Telegraph (London)Christmas, 1859. Just one month after the publication of On the Origin of Species, Charles Darwin received an unsettling letter. He had expected criticism; in fact, letters were arriving daily, most expressing outrage and accusations of heresy. But this letter was different. It accused him of failing to acknowledge his predecessors, of taking credit for a theory that had already been discovered by others. Darwin realized that he had made an error in omitting from Origin of Species any mention of his intellectual forebears. Yet when he tried to trace all of the natural philosophers who had laid the groundwork for his theory, he found that history had already forgotten many of them.Darwin’s Ghosts tells the story of the collective discovery of evolution, from Aristotle, walking the shores of Lesbos with his pupils, to Al-Jahiz, an Arab writer in the first century, from Leonardo da Vinci, searching for fossils in the mine shafts of the Tuscan hills, to Denis Diderot in Paris, exploring the origins of species while under the surveillance of the secret police, and the brilliant naturalists of the Jardin de Plantes, finding evidence for evolutionary change in the natural history collections stolen during the Napoleonic wars. Evolution was not discovered single-handedly, Rebecca Stott argues, contrary to what has become standard lore, but is an idea that emerged over many centuries, advanced by daring individuals across the globe who had the imagination to speculate on nature’s extraordinary ways, and who had the courage to articulate such speculations at a time when to do so was often considered heresy.With each chapter focusing on an early evolutionary thinker, Darwin’s Ghosts is a fascinating account of a diverse group of individuals who, despite the very real dangers of challenging a system in which everything was presumed to have been created perfectly by God, felt compelled to understand where we came from. Ultimately, Stott demonstrates, ideas—including evolution itself—evolve just as animals and plants do, by intermingling, toppling weaker notions, and developing over stretches of time. Darwin’s Ghosts presents a groundbreaking new theory of an idea that has changed our very understanding of who we are.

    Through dramatic graphics and age-appropriate text, this authoritative volume charts the discovery of all the main types of dinosaurs and reveals the latest details on how these creatures most likely looked, behaved, defended themselves, found food, cared for their young, and interacted. Stunning murals, based on scientific evidence, depict various dinosaurs in their habitats--beautifully complementing the color photographs, paintings, charts, and maps. Some 53 major types of dinosaurs are described, representing a wide range of physical structures, sizes, and lifestyles.The book presents recent discoveries and current scientific thought--including the dinosaur-bird connection, profiles of feathered dinosaurs, and theories on dinosaur extinction. Readers also see how today' s paleontologists obtain evidence, piece together clues, and continue to reconstruct life in prehistoric times.

    An artist turned naturalist known for her botanical illustrations, she was born just sixteen years after Galileo proclaimed that the earth orbited the sun. But at the age of fifty she sailed from Europe to the New World on a solo scientific expedition to study insect metamorphosis—an unheard-of journey for any naturalist at that time, much less a woman. When she returned she produced a book that secured her reputation, only to have it savaged in the nineteenth century by scientists who disdained the work of “amateurs.” Exquisitely written and illustrated, Chrysalis takes us from golden-age Amsterdam to the Surinam tropics to modern laboratories where Merian’s insights fuel a new branch of biology. Kim Todd brings to life a seventeenth-century woman whose boldness and vision would still be exceptional today.

    Design journalist Kassia St. Clair guides us through the technological advancements and cultural customs that would redefine human civilization—from the fabric that allowed mankind to achieve extraordinary things (traverse the oceans and shatter athletic records) and survive in unlikely places (outer space and the South Pole). She peoples her story with a motley cast of characters, including Xiling, the ancient Chinese empress credited with inventing silk, to Richard the Lionhearted and Bing Crosby. Offering insights into the economic and social dimensions of clothmaking—and countering the enduring, often demeaning, association of textiles as “merely women’s work”—The Golden Thread offers an alternative guide to our past, present, and future.

    Following the story of marine biologist and animal advocate at the Humane Society of the US, Naomi Rose, Kirby tells the gripping story of the two-decade fight against PR-savvy SeaWorld, which came to a head with the tragic death of trainer Dawn Brancheau in 2010. Kirby puts that horrific animal-on-human attack in context. Brancheau’s death was the most publicized among several brutal attacks that have occurred at Sea World and other marine mammal theme parks. Death at SeaWorld introduces real people taking part in this debate, from former trainers turned animal rights activists to the men and women that champion SeaWorld and the captivity of whales. In section two the orcas act out. And as the story progresses and orca attacks on trainers become increasingly violent, the warnings of Naomi Rose and other scientists fall on deaf ears, only to be realized with the death of Dawn Brancheau. Finally he covers the media backlash, the eyewitnesses who come forward to challenge SeaWorld’s glossy image, and the groundbreaking OSHA case that challenges the very idea of keeping killer whales in captivity and may spell the end of having trainers in the water with the ocean’s top predators.

    These were the animals on the sick list with which Oliver Graham-Jones was presented on his first day as veterinary officer of London Zoo. It was 1950, and the care of wild animals in zoos was in its infancy. Previously sick animals had been placed in the care of their keepers, kept from public view, and if they didn't respond to traditional medications allowed to pass quietly away. But Oliver was to change all this. A pioneer of many of the techniques now used by vets around the world, he was instrumental in building the first animal hospital, and in moving London Zoo away from its Victorian past into the high-tech world of modern veterinary medicine. In Zoo Tails, he tells us about some of the animals he cared for: what it felt like when he was faced with an escaped bear or an injured elephant; and what he did when called upon to perform a colostomy on a python, or when he was asked to fit one of the ravens in the Tower of London with a wooden leg. If a dangerous animal escaped or required urgent medical attention, Oliver Graham-Jones was always on hand, ready for any eventuality. Frequently describing himself as quaking with fear, he

    Thomas Bewick's History of British Birds marked the moment, the first "field guide" for ordinary people, illustrated with woodcuts of astonishing accuracy and beauty. But his work was far more than a mere guide, for in the vivid vignettes scattered through the book, Bewick captured the vanishing world of rural English life.In this superb biography, Jenny Uglow tells the story of the farmer's son from Tyneside who influenced book illustration for a century to come. It is a story of violent change, radical politics, lost ways of life, and the beauty of the wild -- a journey to the beginning of our lasting obsession with the natural world.

    Humans have "subdued 75 per cent of the land surface, concocted a wizardry of industrial and medical marvels, strung lights all across the darkness." We now collect the DNA of vanishing species in a "frozen ark," equip orangutans with iPads, create wearable technologies and synthetic species that might one day outsmart us. With her distinctive gift for making scientific discovery intelligible to the layperson, Ackerman takes us on an exciting journey to understand this bewildering new reality, introducing us to many of the people and ideas now creating--perhaps saving--the future.The Human Ageis a surprising, optimistic engagement with the dramatic transformations that have shaped, and continue to alter, our world, our relationship with nature and our prospects for the future.
