These great beasts, or “megafauna,” lived on every habitable continent and on many islands. With a handful of exceptions, all are now gone.What caused the disappearance of these prehistoric behemoths? No one event can be pinpointed as a specific cause, but several factors may have played a role. Paleomammalogist Ross D. E. MacPhee explores them all, examining the leading extinction theories, weighing the evidence, and presenting his own conclusions. He shows how theories of human overhunting and catastrophic climate change fail to account for critical features of these extinctions, and how new thinking is needed to elucidate these mysterious losses.Along the way, we learn how time is determined in earth history; how DNA is used to explain the genomics and phylogenetic history of megafauna—and how synthetic biology and genetic engineering may be able to reintroduce these giants of the past. Until then, gorgeous four-color illustrations by Peter Schouten re-create these megabeasts here in vivid detail.

    The Extreme Life of the Sea takes readers to the absolute limits of the ocean world--the fastest and deepest, the hottest and oldest creatures of the oceans. It dives into the icy Arctic and boiling hydrothermal vents--and exposes the eternal darkness of the deepest undersea trenches--to show how marine life thrives against the odds. This thrilling book brings to life the sea's most extreme species, and tells their stories as characters in the drama of the oceans. Coauthored by Stephen Palumbi, one of today's leading marine scientists, The Extreme Life of the Sea tells the unforgettable tales of some of the most marvelous life forms on Earth, and the challenges they overcome to survive. Modern science and a fluid narrative style give every reader a deep look at the lives of these species.The Extreme Life of the Sea shows you the world's oldest living species. It describes how flying fish strain to escape their predators, how predatory deep-sea fish use red searchlights only they can see to find and attack food, and how, at the end of her life, a mother octopus dedicates herself to raising her batch of young. This wide-ranging and highly accessible book also shows how ocean adaptations can inspire innovative commercial products--such as fan blades modeled on the flippers of humpback whales--and how future extremes created by human changes to the oceans might push some of these amazing species over the edge.An enhanced edition is also available and includes eleven videos.

    On the one hand wrens are ubiquitous. They are Britain's most common bird, with 8.5 million breeding pairs and have by far the loudest song in proportion to their size. They also thrive up and down Britain and Ireland: from the smallest city garden to remote offshore islands, blustery moors to chilly mountains. Yet many people, particularly a younger generation, are not sure if they have ever seen a wren. Perhaps because the wren is so tiny, weighing just as much as two A4 sheets of paper, and so busy, always on the move, more mouse than bird. However if we cast our eyes back to recent history wrens were a mainstay of literary, cultural and popular history. The wren was on postage stamps and the farthing, it featured in nursery rhymes and greetings cards, poems and rural `wren hunts', still a recent memory in Ireland particularly. With beautiful illustrations throughout, this captivating year-in-the-life biography reveals the hidden secrets of this fascinating bird that lives right on our doorstep.

    Mysteries don't lose their poetry because they are solved: the solution often is more beautiful than the puzzle, uncovering deeper mysteries. With the wit, insight, and spellbinding prose that have made him a best-selling author, Dawkins takes up the most important and compelling topics in modern science, from astronomy and genetics to language and virtual reality, combining them in a landmark statement of the human appetite for wonder. This is the book Richard Dawkins was meant to write: a brilliant assessment of what science is (and isn't), a tribute to science not because it is useful but because it is uplifting.

    He stated that, within fifty to eighty years, we would see the consequences of mechanizing the forces that had previously operated organically in the beehive. Such practices include breeding queen bees artificially.The fact that over sixty percent of the American honeybee population has died during the past ten years, and that this trend is continuing around the world, should make us aware of the importance of the issues discussed in these lectures. Steiner began this series of lectures on bees in response to a question from an audience of workers at the Goetheanum.From physical depictions of the daily activities of bees to the most elevated esoteric insights, these lectures describe the unconscious wisdom of the beehive and its connection to our experience of health, culture, and the cosmos.Bees is essential reading for anyone interested in understanding the true nature of the honeybee, as well as those who wish to heal the contemporary crisis of the beehive. Bees includes an essay by David Adams, "From Queen Bee to Social Sculpture: The Artistic Alchemy of Joseph Beuys."The art and social philosophy of Joseph Beuys (1921-1986) is among the most influential of the twentieth century. He was strongly influenced by Rudolf Steiner's lectures on bees. The elemental imagery and its relationship to human society played an important role in Beuys's sculptures, drawings, installations, and performance art. Adams' essay on Beuys adds a whole new dimension to these lectures, generally considered to be directed more specifically to biodynamic methods and beekeeping.C O N T E N T SIntroduction by Gunther HaukEight Lectures by Rudolf SteinerBlackboard DrawingsAppendix" Extracts from Various LecturesAfterword by David Adams: "From Queen Bee to Social Sculpture: The Artistic Alchemy of Joseph Beuys"IndexThis volume consists of 8 lectures (of 15) from Mensch und Welt.

    L. Langstroth, "the father of modern beekeeping," revolutionized the practice of beekeeping. Originally published in 1853, his work constitutes the first descriptive treatise of modern bee management — its innovations allowed people to engage in actual beekeeping, rather than simply handling bee domiciles and extracting the honey. This book explains and illustrates techniques still employed 150 years later — including the author's patented invention, a movable frame hive that quickly spread into common use around the world.In his reader-friendly, nontechnical style, Langstroth addresses every aspect of beekeeping: bee physiology; diseases and enemies of bees; the life-cycles of the queen, drone, and worker; bee-hives; and the handling of bees. An infectious sense of wonder and enthusiasm suffuses Langstroth's accounts of natural and artificial swarming, the production of honey and wax, and the best methods of feeding bees and maintaining an apiary. The manual abounds in practical and intriguing insights attained through the years of observation and experience, including "the kindness of bees to one another," "their infatuation for liquid sweets," and "the warning given by bees before stinging."This version of Langstroth's ever-popular manual is the fourth and final edition; it incorporates the author's own revisions and remains an unsurpassed resource for beekeepers.

    . . . This is an exciting book. Although Schaller feels that this is 'not an adventure book,' few readers will be able to agree."—Irven DeVore, Science

    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.

    Studies the work and unique methods of three women scientists who contributed to understanding chimpanzees, mountain gorillas, and orangutans.

    Oceans cover two-thirds of the earth's surface with an average depth of more than two miles--yet humans had never ventured more than a few hundred feet below the waves. One of the great scientific and archaeological feats of our time has been finally to cast light on the eternal darkness of the deep sea. This is the story of that achievement, told by the man who has done more than any other to make it possible: Robert Ballard.Ballard discovered the wreck of the Titanic. He led the teams that discovered hydrothermal vents and black smokers--cracks in the ocean floor where springs of superheated water support some of the strangest life-forms on the planet. He was a diver on the team that explored the mid-Atlantic ridge for the first time, confirming the theory of plate tectonics. Today, using a nuclear submarine from the U.S. Navy, he's exploring the ancient trade routes of the Mediterranean and the Black Sea for the remains of historic vessels and their cargo. In this book, he combines science, history, spectacular illustrations, and first-hand stories from his own expeditions in a uniquely personal account of how twentieth-century explorers have pushed back the frontiers of technology to take us into the midst of a world we could once only guess at.Ballard begins in 1930 with William Beebe and Otis Barton, pioneers of the ocean depths who made the world's first deep-sea dives in a cramped steel sphere. He introduces us to Auguste and Jacques Piccard, whose Bathyscaphdescended in 1960 to the lowest point on the ocean floor. He reviews the celebrated advances made by Jacques Cousteau. He describes his own major discoveries--from sea-floor spreading to black smokers--as well as his technical breakthroughs, including the development of remote-operated underwater vehicles and the revolutionary search techniques that led to the discovery and exploration of the Titanic, the Nazi battleship Bismarck, ancient trading vessels, and other great ships.Readers will come away with a richer understanding of history, earth science, biology, and marine technology--and a new appreciation for the remarkable men and women who have explored some of the most remote and fascinating places on the planet.

    For the past several years, acclaimed Science reporter Jon Cohen has been following the DNA hunt, as well as eye-opening new studies in ape communication, human evolution, disease, diet, and more.In Almost Chimpanzee, Cohen invites us on a captivating scientific journey, taking us behind the scenes in cutting-edge genetics labs, rain forests in Uganda, sanctuaries in Iowa, experimental enclaves in Japan, even the Detroit Zoo. Along the way, he ferries fresh chimp sperm for a time-sensitive analysis, gets greeted by pant-hoots and chimp feces, and investigates an audacious attempt to breed a humanzee. Cohen offers a fresh and often frankly humorous insider's tour of the latest research, which promises to lead to everything from insights about the unique ways our bodies work to shedding light on stubborn human-only problems, ranging from infertility and asthma to speech disorders.And in the end, Cohen explains why it's time to move on from Jane Goodall's plea that we focus on how the two species are alike and turns to examining why our differences matter in vital ways—for understanding humans and for increasing the chances to save the endangered chimpanzee.
