. . A tour de force of a book that begs to be seen as well as to be read."--The Washington Post Book WorldWorld renowned scientist Carl Sagan and acclaimed author Ann Druyan have written a Roots for the human species, a lucid and riveting account of how humans got to be the way we are. Shadows of Forgotten Ancestors is a thrilling saga that starts with the origin of the Earth. It shows with humor and drama that many of our key traits--self-awareness, technology, family ties, submission to authority, hatred for those a little different from ourselves, reason, and ethics--are rooted in the deep past, and illuminated by our kinship with other animals.Sagan and Druyan conduct a breathtaking journey through space and time, zeroing in on critical turning points in evolutionary history, and tracing the origins of sex, altruism, violence, rape, and dominance. Their book culminates in a stunningly original examination of the connection between primate and human traits. Astonishing in its scope, brilliant in its insights, and an absolutely compelling read, Shadows of Forgotten Ancestors is a triumph of popular science.

    He proposes that we look at evolution as a battle between genes instead of between whole organisms. We can then view changes in phenotypes—the end products of genes, like eye color or leaf shape, which are usually considered to increase the fitness of an individual—as serving the evolutionary interests of genes.Dawkins makes a convincing case that considering one’s body, personality, and environment as a field of combat in a kind of “arms race” between genes fighting to express themselves on a strand of DNA can clarify and extend the idea of survival of the fittest. This influential and controversial book illuminates the complex world of genetics in an engaging, lively manner.

    Authors Peter Tompkins and Christopher Bird suggest that the most far-reaching revolution of the 20th century — one that could save or destroy the planet — may come from the bottom of your garden."Almost incredible ... bristles with plenty of hard facts and astounding scientific and practical lore." —S. K. Oberbeck, Newsweek“This fascinating book roams ... over that marvelous no man's land of mystical glimmerings into the nature of science and life itself." —Henry Mitchell, Washington Post Book World“If I can't ‘get inside a plant’ or ‘feel emanations’ from a plant and don't know anyone else who can. that doesn't detract one whit from the possibility that some people can and do. . . .According to The Secret Life of Plants, plants and men do inter-relate, with plants exhibiting empathetic and spiritual relationships and showing reactions interpreted as demonstrating physical-force connections with men. As my students say, ‘hey, wow!’"—Richard M. Klein, Professor of Botany, University of Vermont (in Smithsonian)

    Thanks largely to YouTube clips posted by the sloth orphanage in Costa Rica, sloths have attracted a vast audience of admirers. Instead of seeing them as ridiculous anachronisms of which we know little, they have turned into creatures considered by many to be the most endearing on earth.Over much the same period, scientific investigations have also changed our view of sloths. No longer are they seen as total misfits in the modern world but, in the words of one specialist sloth investigator, they are 'masters of an alternative lifestyle'.In this wonderfully entertaining celebration of this most unique of creatures, William Hartston reveals the fascinating history of the sloth, from the prehistoric ground sloth to modern pygmy sloths in Panama, explores the current state of the science of sloths and reveals the truth behind sloth behaviour.

    Journalist Elizabeth Royte weaves together her own adventures on Barro Colorado with tales of researchers struggling to parse the intricate workings of a tropical rain forest. As Royte works alongside the scientists � sorting insects, collecting monkey dung, radiotracking fruit bats � she asks: What is the point of such research? Both "moving and satisfying" (Providence Sunday Journal), The Tapir's Morning Bath humanizes the scientists, who are driven by passion and ambition to explore arcane questions even though the world may not have time to wait for the answers.

    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.

    In this book on "people-training for dog trianers," Nicole Wilde shares advice based on years of experience as a professional dog trainer. She teaches the reader the basics of "people training," how to coach clients using positive reinforcement and other techniques. In an often humorous section, Wilde describes specific types of difficult personality types, from Angry Agnes to Unmotivated Mo, and how specifically to deal with them. Also covered are handling students in a group class setting, working one on one in private lessons, and understanding and working with family dynamics. An invaluable resource for any dog trainer.

    Former veterinary technician and animal advocate Tracey Stewart understands this better than most—and she’s on a mission to change how we interact with animals. Through hundreds of charming illustrations, a few homemade projects, and her humorous, knowledgeable voice, Stewart provides insight into the secret lives of animals and the kindest ways to live with and alongside them. At home, she shows readers how to speak “dog-ese” and “cat-ese” and how to “virtually adopt” an animal. In the backyard, we learn about building bee houses, dealing nicely with pesky moles, and creative ways to bird-watch. And on the farm, Stewart teaches us what we can do to help all farm animals lead a better life (and reveals pigs’ superpowers!). Part practical guide, part memoir of her life with animals, and part testament to the power of giving back, Do Unto Animals is a gift for animal lovers of all stripes.

    The story of a lifetime of such minute explorations, For Love of Insects celebrates the small creatures that have emerged triumphant on the planet, the beneficiaries of extraordinary evolutionary inventiveness and unparalleled reproductive capacity. Eisner tells us, but never has a reckoning been such a pleasure. Recounting exploits and discoveries in his laboratory at Cornell and in the field in Uruguay, Australia, Panama, Europe and North America, Eisner time and again demonstrates how inquiry into the survival strategies of an insect leads to clarifications beyond the expected; insects are revealed as masters of achievement, forms of life worthy of study and respect from even the most recalcitrant entomophobe. Filled with descriptions of his ingenious experiments and illustrated with photographs, this book makes readers participants in the grand adventure of discovery on a scale infinitesimally small and infinitely surprising.

    This book is the record of her experiences. It’s a stunning collection of carefully observed accounts of her life—tracking otters on the beach, cooking breakfast in the desert, canoeing in a snow squall, wading among migrating salmon in the dark—but it is also a profound meditation on the healing power of nature.

    The book emphasizes a general introduction to probability theory and provides a detailed discussion of specific designs and analyses that are typically encountered in ecology and environmental science. Appropriate for use as either a stand-alone or supplementary text for upper-division undergraduate or graduate courses in ecological and environmental statistics, ecology, environmental science, environmental studies, or experimental design, the Primer also serves as a resource for environmental professionals who need to use and interpret statistics daily but have little or no formal training in the subject.

    No, not only, but to some extent. Here and there, my story is about something else.” A mesmerizing memoir of extraordinary brilliance by an entomologist, The Fly Trap chronicles Fredrik Sjöberg’s life collecting hoverflies on a remote island in Sweden. Warm and humorous, self-deprecating and contemplative, and a major best seller in its native country, The Fly Trap is a meditation on the unexpected beauty of small things and an exploration of the history of entomology itself.   What drives the obsessive curiosity of collectors to catalog their finds? What is the importance of the hoverfly? As confounded by his unusual vocation as anyone, Sjöberg reflects on a range of ideas—the passage of time, art, lost loves—drawing on sources as disparate as D.H. Lawrence and the fascinating and nearly forgotten naturalist René Edmond Malaise. From the wilderness of Kamchatka to the loneliness of the Swedish isle he calls home, Sjöberg revels in the wonder of the natural world and leaves behind a trail of memorable images and stories.
