Fully grown they can measure 10 feet and weigh close to 2,000 pounds, but at birth they are just 20 ounces. Creatures that may wander thousands of miles over the course of a year, they begin life in a snowdrift.Human encounters with these legendary beasts are cause for both excitement and apprehension. Tales throughout history describe the ferocity of polar bear attacks on humans; but human hunting of polar bears has exacted a far larger toll, obliging Arctic nations to try to protect their region’s iconic species before it’s too late.Now, however, another threat to the polar bears’ survival has emerged, one that is steadily removing sea ice and the life it supports. Without this habitat, polar bears cannot exist. The Great White Bear celebrates the story of this unique species. Through a blend of history, both natural and human, through myth and reality and observations both personal and scientific, Kieran Mulvaney masterfully provides a context for readers to consider the polar bear, its history, its life, and its uncertain fate.

    Her reward for the grueling work of rescuing birds—such as feeding baby hummingbirds every twenty minutes all day long—is her empathy with them and the satisfaction of knowing the world is a birdier and more beautiful place. The Bluebird Effect is about the change that's set in motion by one single act, such as saving an injured bluebird—or a hummingbird, swift, or phoebe. Each of the twenty five chapters covers a different species, and many depict an individual bird, each with its own personality, habits, and quirks. And each chapter is illustrated with Zickefoose's stunning watercolor paintings and drawings. Not just individual tales about the trials and triumphs of raising birds, The Bluebird Effect mixes humor, natural history, and memoir to give readers an intimate story of a life lived among wild birds.

    It is the root of our existence, supporting our feet, our farms, our cities. This fascinating yet disquieting book finds, however, that we are running out of dirt, and it's no laughing matter. An engaging natural and cultural history of soil that sweeps from ancient civilizations to modern times, Dirt: The Erosion of Civilizations explores the compelling idea that we are—and have long been—using up Earth's soil. Once bare of protective vegetation and exposed to wind and rain, cultivated soils erode bit by bit, slowly enough to be ignored in a single lifetime but fast enough over centuries to limit the lifespan of civilizations. A rich mix of history, archaeology and geology, Dirt traces the role of soil use and abuse in the history of Mesopotamia, Ancient Greece, the Roman Empire, China, European colonialism, Central America, and the American push westward. We see how soil has shaped us and we have shaped soil—as society after society has risen, prospered, and plowed through a natural endowment of fertile dirt. David R. Montgomery sees in the recent rise of organic and no-till farming the hope for a new agricultural revolution that might help us avoid the fate of previous civilizations.

    Presenting details about the parts of the skull (including the cranium, the mandible, the shape and positioning of the eye sockets, and species-specific features like horns, teeth, beaks and bills), information about the science and pseudoscience of skulls, and a look at skulls in religion, art and popular culture, his stories and information are riveting and enlightening.At the center of "Skulls" is a stunning, never-before-seen-in-any-capacity, visual array of the skulls of more than 300 animals that walk, swim, and fly. The skulls are from the collection of Alan Dudley, a British collector and owner of what is probably the largest and most complete private collection of skulls in the world. Every skull is beautifully photographed to show several angles and to give the reader the most intimate view possible. Each includes a short explanatory paragraph and a data box with information on the animal's taxonomy, behavior, and diet."Skulls "was published in December 2011 as an e-book for the iPad by the innovative e-book publishers Touch Press, creators of the best-selling e-books for iPad "The Elements" and "Solar System."

    It hold the remains of an ancient sea where dozens of strange creatures lived—a forgotten corner of evolution preserved in awesome detail. In this book Stephen Jay Gould explores what the Burgess Shale tells us about evolution and the nature of history.

    He began his career making films for the TV series "Survival," which started wildlife film-making as we know it, and is responsible for numerous groundbreaking documentaries and natural history discoveries -- from being the first person to film hippos and crocodiles underwater and the wildebeest migrating to observing that hyenas hunt. His friends and colleagues have included George and Joy Adamson and David Attenborough; he showed Dian Fossey her first mountain gorilla. His wife and long-term collaborator was Joan Root, who was tragically murdered in 2006 in retaliation for her environmental campaigning in Kenya. In "Ivory, Apes & Peacocks," Alan tells the story of his life's work, from his arrival in Kenya as a young boy (furious at having to leave behind Britain's birds) to his game-changing films, which looked at whole ecosystems (baobab trees, termite mounds) rather than the Big Five animals. Along the way we encounter Sally the pet hippo and Emily the house-proud chimp as well leopard and snake bites, ballooning adventures and amphibious cars. In this extraordinary memoir we look at Africa's wonders through the eyes of a visionary, live through hair-raising adventure and personal tragedy and also bear witness to a natural world now largely lost from view.

A fine addition to school libraries at all levels."--(starred) Science Books & Films.

    A story of defiance and determination by a controversial scientist, this is Lee Berger's own take on finding Homo naledi, an all-new species on the human family tree and one of the greatest discoveries of the 21st century.In 2013, Berger, a National Geographic Explorer-in-Residence, caught wind of a cache of bones in a hard-to-reach underground cave in South Africa. He put out a call around the world for petite collaborators--men and women small and adventurous enough to be able to squeeze through 8-inch tunnels to reach a sunless cave 40 feet underground. With this team of "underground astronauts," Berger made the discovery of a lifetime: hundreds of prehistoric bones, including entire skeletons of at least 15 individuals, all perhaps two million years old. Their features combined those of known prehominids like Lucy, the famous Australopithecus, with those more human than anything ever before seen in prehistoric remains. Berger's team had discovered an all new species, and they called it Homo naledi.The cave quickly proved to be the richest primitive hominid site ever discovered, full of implications that shake the very foundation of how we define what makes us human. Did this species come before, during, or after the emergence of Homo sapiens on our evolutionary tree? How did the cave come to contain nothing but the remains of these individuals? Did they bury their dead? If so, they must have had a level of self-knowledge, including an awareness of death. And yet those are the very characteristics used to define what makes us human. Did an equally advanced species inhabit Earth with us, or before us? Berger does not hesitate to address all these questions.Berger is a charming and controversial figure, and some colleagues question his interpretation of this and other finds. But in these pages, this charismatic and visionary paleontologist counters their arguments and tells his personal story: a rich and readable narrative about science, exploration, and what it means to be human.

    In tracing how we ended up positioning our nondescript penis as a pulsing, awe-inspiring shaft of all masculinity and human dominance,.Emphasizing our human capacities for impulse control, Phallacy ultimately challenges the message that the penis makes the man and the man can't control himself. With instructive illustrations of unusual genitalia and tales of animal mating rituals Phallacy shows where humans fit on the continuum from fun to fatal phalli and why the human penis is an implement for intimacy, not intimidation.

    Both evoke a similar sensation in us — we find them beautiful and magical, but also spooky, sometimes horrifying.In this fascinating book, Maitland argues that the two forms are intimately connected: the mysterious secrets and silences, gifts and perils of the forests were both the background and the source of fairytales. Yet both forests and fairy stories are at risk and their loss deprives us of our cultural lifeblood. Maitland visits forests through the seasons, from the exquisite green of a beechwood in spring, to the muffled stillness of a snowy pine wood in winter. She camps with her son Adam, whose beautiful photographs are included in the book; she takes a barefoot walk through Epping Forest with Robert Macfarlane; she walks with a mushroom expert through an oak wood, and with a miner through the Forest of Dean. Maitland ends each chapter with a unique, imaginitive re-telling of a fairystory.Written with Sara's wonderful clarity and conversational grace, Gossip from the Forest is a magical and unique blend of nature writing, history and imaginative fiction.
