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.

    MacKinnon realized the grassland he grew up on was not the pristine wilderness he had always believed it to be. Instead, his home prairie was the outcome of a long history of transformation, from the disappearance of the grizzly bear to the introduction of cattle. What remains today is an illusion of the wild--an illusion that has in many ways created our world. In 3 beautifully drawn parts, MacKinnon revisits a globe exuberant with life, where lions roam North America and 20 times more whales swim in the sea. He traces how humans destroyed that reality, out of rapaciousness, yes, but also through a great forgetting. Finally, he calls for an "age of restoration," not only to revisit that richer and more awe-filled world, but to reconnect with our truest human nature. MacKinnon never fails to remind us that nature is a menagerie of marvels. Here are fish that pass down the wisdom of elders, landscapes still shaped by "ecological ghosts," a tortoise that is slowly remaking prehistory. "It remains a beautiful world," MacKinnon writes, "and it is its beauty, not its emptiness, that should inspire us to seek more nature in our lives."

    

    The expedition was described by the two men in Sea of Cortez, published in 1941. The day-to-day story of the trip is told here in the Log, which combines science, philosophy and high-spirited adventure.Log from the Sea of Cortez includes the narrative of the journey and the essay “About Ed Ricketts.” It does not include pictures and detailed descriptions of the species collected by Steinbeck and Ricketts. (See also Sea of Cortez.)

    Half-poet and half-geologist, he recorded his experiences and reflections in Travels in Alaska, a work he was in the process of completing at the time of his death in 1914. As Edward Hoagland writes in his Introduction, “A century and a quarter later, we are reading [Muir’s] account because there in the glorious fiords . . . he is at our elbow, nudging us along, prompting us to understand that heaven is on earth—is the Earth—and rapture is the sensible response wherever a clear line of sight remains.”This Modern Library Paperback Classic includes photographs from the original 1915 edition.

    Many people think of microbes as germs to be eradicated, but those that live with us—the microbiome—build our bodies, protect our health, shape our identities, and grant us incredible abilities. In this astonishing book, Ed Yong takes us on a grand tour through our microbial partners, and introduces us to the scientists on the front lines of discovery. Yong, whose humor is as evident as his erudition, prompts us to look at ourselves and our animal companions in a new light—less as individuals and more as the interconnected, interdependent multitudes we assuredly are. The microbes in our bodies are part of our immune systems and protect us from disease. Those in cows and termites digest the plants they eat. In the deep oceans, mysterious creatures without mouths or guts depend on microbes for all their energy. Bacteria provide squids with invisibility cloaks, help beetles to bring down forests, and allow worms to cause diseases that afflict millions of people. I Contain Multitudes is the story of these extraordinary partnerships, between the creatures we are familiar with and those we are not. It reveals how we humans are disrupting these partnerships and how we might manipulate them for our own good. It will change both our view of nature and our sense of where we belong in it.

    Congress declared the locust “the single greatest impediment to the settlement of the country between Mississippi and the Rocky Mountains.” Throughout the nineteenth century, swarms of locusts regularly swept across the American continent, turning noon into dusk, devastating farm communities, and bringing trains to a halt. The outbreaks subsided in the 1890s, and then, suddenly—and mysteriously—the Rocky Mountain locust vanished. A century later, entomologist Jeffrey Lockwood vowed to discover why.Locust is the story of how one insect shaped the history of the western United States. A compelling personal narrative drawing on historical accounts and modern science, this beautifully written book brings to life the cultural, economic, and political forces at work in America in the late nineteenth century, even as it solves one of the greatest extinction mysteries of our time.

    The unforgiving territory along the Bering Strait had long been home to humans—the Inupiat and Yupik in Alaska, and the Yupik and Chukchi in Russia—before Americans and Europeans arrived with revolutionary ideas for progress. Rapidly, these frigid lands and waters became the site of an ongoing experiment: How, under conditions of extreme scarcity, would the great modern ideologies of capitalism and communism control and manage the resources they craved?Drawing on her own experience living with and interviewing indigenous people in the region, as well as from archival sources, Demuth shows how the social, the political, and the environmental clashed in this liminal space. Through the lens of the natural world, she views human life and economics as fundamentally about cycles of energy, bringing a fresh and visionary spin to the writing of human history.Floating Coast is a profoundly resonant tale of the dynamic changes and unforeseen consequences that immense human needs and ambitions have brought, and will continue to bring, to a finite planet.

    In the great halls of science, dogma holds that Darwin's theory of natural selection explains every branch on the tree of life: which species thrive, which wither away to extinction, and what features each evolves. But can adaptation by natural selection really account for everything we see in nature? Yale University ornithologist Richard Prum--reviving Darwin's own views--thinks not. Deep in tropical jungles around the world are birds with a dizzying array of appearances and mating displays: Club-winged Manakins who sing with their wings, Great Argus Pheasants who dazzle prospective mates with a four-foot-wide cone of feathers covered in golden 3D spheres, Red-capped Manakins who moonwalk. In thirty years of fieldwork, Prum has seen numerous display traits that seem disconnected from, if not outright contrary to, selection for individual survival. To explain this, he dusts off Darwin's long-neglected theory of sexual selection in which the act of choosing a mate for purely aesthetic reasons--for the mere pleasure of it--is an independent engine of evolutionary change. Mate choice can drive ornamental traits from the constraints of adaptive evolution, allowing them to grow ever more elaborate. It also sets the stakes for sexual conflict, in which the sexual autonomy of the female evolves in response to male sexual control. Most crucially, this framework provides important insights into the evolution of human sexuality, particularly the ways in which female preferences have changed male bodies, and even maleness itself, through evolutionary time. The Evolution of Beauty presents a unique scientific vision for how nature's splendor contributes to a more complete understanding of evolution and of ourselves.

    Wars have been fought over it, revolutions have been triggered by it, national diets have been based on it, economies and livelihoods have depended on it. To the millions it has sustained, it has been a treasure more precious that gold. This book spans 1,000 years and four continents. From the Vikings to Clarence Birdseye, Mark Kurlansky introduces the explorers, merchants, writers, chefs and fisherman, whose lives have been interwoven with this prolific fish. He chronicles the cod wars of the 16th and 20th centuries. He blends in recipes and lore from the Middle Ages to the present. In a story that brings world history and human passions into captivating focus, he shows how the most profitable fish in history is today faced with extinction.

    Author David Helvarg takes the reader on both a geographic and literary journey along the 1,100-mile Pacific coastline, from the Oregon border to the San Diego/Tijuana international border fence and out into its whale-, seal-, and shark-rich offshore seamounts, rock isles, and kelp forests.Part history, part travelogue, part love letter, The Golden Shore tells the story of California’s majestic coastline and ocean. Helvarg captures the spirit of the Californian coast, its mythic place in American culture, and its role in a state whose ongoing natural disasters and unremitting sense of renewal are intimately linked to its deep connection with an ever-changing sea.

    In Beloved Beasts, acclaimed science journalist Michelle Nijhuis traces the movement’s history: from early battles to save charismatic species such as the American bison and bald eagle to today’s global effort to defend life on a larger scale.She describes the vital role of scientists and activists such as Aldo Leopold and Rachel Carson as well as lesser-known figures in conservation history; she reveals the origins of vital organizations like the Audubon Society and the World Wildlife Fund; she explores current efforts to protect species such as the whooping crane and the black rhinoceros; and she confronts the darker side of conservation, long shadowed by racism and colonialism.As the destruction of other species continues and the effects of climate change escalate, Beloved Beasts charts the ways conservation is becoming a movement for the protection of all species—including our own.
