The down beats of their wings would chill the air beneath and create a thundering roar that would drown out all other sound. Feeding flocks would appear as “a blue wave four or five feet high rolling toward you.”John James Audubon, impressed by their speed and agility, said a lone passenger pigeon streaking through the forest “passes like a thought.” How prophetic-for although a billion pigeons crossed the skies 80 miles from Toronto in May of 1860, little more than fifty years later passenger pigeons were extinct. The last of the species, Martha, died in captivity at the Cincinnati Zoo on September 1, 1914.As naturalist Joel Greenberg relates in gripping detail, the pigeons' propensity to nest, roost, and fly together in vast numbers made them vulnerable to unremitting market and recreational hunting. The spread of railroads and telegraph lines created national markets that allowed the birds to be pursued relentlessly. Passenger pigeons inspired awe in the likes of Audubon, Henry David Thoreau, James Fenimore Cooper, and others, but no serious effort was made to protect the species until it was way too late. Greenberg's beautifully written story of the passenger pigeon provides a cautionary tale of what happens when species and natural resources are not harvested sustainably.

    His powerful message, conveyed with humor, compassion, and art: to know these animals is to save them.Sartore intends to photograph every animal in captivity in the world. He is circling the globe, visiting zoos and wildlife rescue centers to create studio portraits of 12,000 species, with an emphasis on those facing extinction. He has photographed more than 6,000 already and now, thanks to a multi-year partnership with National Geographic, he may reach his goal. This book showcases his animal portraits: from tiny to mammoth, from the Florida grasshopper sparrow to the greater one-horned rhinoceros. Paired with the eloquent prose of veteran wildlife writer Douglas Chadwick, this book presents a thought-provoking argument for saving all the species of our planet.

    With whimsically hip illustrations, every page is an extraordinary look at all kinds of subjects, from mineral formation and the inside of a volcano to what makes sunsets, monarch butterfly migration, the ecosystem of a rotting log, the parts of a bird, the anatomy of a jellyfish, and much, much more.

    An evolutionary perspective forms the foundation of the entire discussion. The book begins with the natural history of the planet, considers portions of the whole in the middle chapters, and ends with another perspective of the entire planet in the concluding chapter. Its unique organization of focusing only on several key concepts in each chapter sets it apart from the competition. .

    With 16 pages of extraordinary photographs.

    Fossey's extraordinary efforts to ensure the future of the rain forest and its remaining mountain gorillas are captured in her own words and in candid photographs of this fascinating endangered species. As only she could, Fossey combined her personal adventure story with groundbreaking scientific reporting in an unforgettable portrait of one of our closest primate relatives. Although Fossey's work ended tragically in her murder, Gorillas in the Mist remains an invaluable testament to one of the longest-running field studies of primates and reveals her undying passion for her subject.

    Every field, forest, and park is full of living organisms adapted for relationships with creatures that are now extinct. In a vivid narrative, Connie Barlow shows how the idea of "missing partners" in nature evolved from isolated, curious examples into an idea that is transforming how ecologists understand the entire flora and fauna of the Americas. This fascinating book will enrich and deepen the experience of anyone who enjoys a stroll through the woods or even down an urban sidewalk. But this knowledge has a dark side too: Barlow's "ghost stories" teach us that the ripples of biodiversity loss around us now are just the leading edge of what may well become perilous cascades of extinction.

    

    This claim is not only false, but its presence in the debate is an insult to science." With these words, the authors begin a detailed analysis of one of the most controversial topics of the day. The authors make a compelling case against claims of a scientific consensus. The purported proof of such a consensus consists of sloppy research by nonscientists, college students, and a highly partisan Australian blogger. Surveys of climate scientists, even those heavily biased in favor of climate alarmism, find extensive disagreement on the underlying science and doubts about its reliability. The authors point to four reasons why scientists disagree about global warming: a conflict among scientists in different and often competing disciplines; fundamental scientific uncertainties concerning how the global climate responds to the human presence; failure of the United Nations Intergovernmental Panel on Climate Change (IPCC) to provide objective guidance to the complex science; and bias among researchers. The authors offer a succinct summary of the real science of climate change based on their previously published comprehensive review of climate science in a volume titled Climate Change Reconsidered II: Physical Science. They recommend that policymakers resist pressure from lobby groups to silence scientists who question the authority of the IPCC to claim to speak for climate science. More than 50,000 copies of the first edition were sold or given away in five months to elected officials, civic and business leaders, scientists, and other opinion leaders. The response from the science community and experts on climate change has been overwhelmingly positive. To meet demand for more copies, we have produced this second revised edition. Changes include a foreword by Marita Noon, at the time executive director of Energy Makes America Great, Inc. Some of the discussion in Chapter 1 has been revised and expanded thanks to feedback from readers of the first edition. Graphs in Chapters 4, 5, and 6 are now full color, and new graphs have been added.

    Touching the Wild is the enchanting story about one man who has lived with a herd of mule deer in the Wind River mountains of Wyoming for almost seven years. Why, you may ask, would a person choose to do such a thing? His response: how could you not? For Joe Hutto, close proximity to wild things is irresistible. In Illumination in the Flatwoods he unveiled the secret lives of the wild turkey to great critical acclaim. In Touching the Wild he turns his acute sense of wonder and affinity to one of the West's quintessential big game animals: the mule deer, a species in peril due to environmental factors. Wily, thoughtful creatures, mule deer are not inclined to make foolish friendships with their primary predator-man. But due to the intense curiosity of one small doe, and the resulting introduction to an entire herd, Joe Hutto has been allowed unprecedented access and insight into the minds and behavior of this special animal.Spending every day among the herd, he develops uncanny connections with the deer, learning individual and group dynamics as well, unveiling just how much we have in common with these delicate beings. Each season brings new joy as fawns are born and heartache as matriarchs pass away, or hunting takes its toll, or a fawn is orphaned. But what overwhelmingly emerges from Touching the Wild is the enormous respect Hutto has for all wild things and the recognition that we have so much to learn from them about their world, ourselves, and the fragile planet we share. Throughout the book are gorgeous full-color photos.

    Its authors present a new view of cognition that has important social and ethical implications, for, they assert, the only world we humans can have is the one we create together through the actions of our coexistence. Written for a general audience as well as for students, scholars, and scientists and abundantly illustrated with examples from biology, linguistics, and new social and cultural phenomena, this revised edition includes a new afterword by Dr. Varela, in which he discusses the effect the book has had in the years since its first publication.

    Humans are the adult wolf’s only true natural predator; its return to the old-growth forests and wild coastlines of the Pacific Northwest renews age-old questions about the value of wildlands and wildlife.      As the vivid stories unfold in this riveting and timely book, wolves emerge as smart, complex players uniquely adapted to the vast interdependent ecosystem of this stunning region. Observing them at close range, David Moskowitz explores how they live, hunt, and communicate, tracing their biology and ecology through firsthand encounters in the wildlands of the Northwest. In the process he challenges assumptions about their role and the impact of even well-meaning human interventions.

    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.

    Its geology, its unique flora and fauna, and its striking role in human history intersect in surprising and dynamic ways. This book is the most wide-ranging and beautifully illustrated book available on the famous islands. Not since Darwin’s Naturalist’s Voyage has a book combined so much scientific and historic information with firsthand accounts that bring the Galápagos to life.Galápagos: The Islands That Changed the World describes how tragedy and murderous pirates curtailed settlement of the islands and how the islands’ pristine nature, spectacular geology, and defining isolation inspired Darwin’s ideas about evolution. The book explores the diverse land and marine habitats that shelter Galápagos species and considers the islands’ importance today as a frontier for science and a refuge for true wilderness. The book’s extensive gazetteer provides details about endemic plants and animals as well as travel advice about visitors’ sites, diving, photography, when to go, and what to take. Vividly illustrated throughout, this guide is an indispensable reference for natural history enthusiasts, armchair travelers, and island visitors alike.
