DOWNLOAD EBOOKPredatory Bureaucracy is the definitive history of America's wolves and our policies toward predators. Tracking wolves from Coronado's day to the present, author Michael Robinson shows that their story merges with that of the U.S. Bureau of Biological Survey. This federal agency was chartered to research insects and birds but'because of various pressures'morphed into a political powerhouse operating wildlife-extermination programs. Drawing on deep research and wide reading, Robinson's narrative follows the wolves from the eras of explorers and mountain men through the wolves' 120-year entanglement with the federal government. He shares the parallel story of the Survey's rise, detailing the forces that allowed extermination programs to continue'despite opposition from hunters, animal lovers, scientists, environmentalists, and presidents'though the agency's mission and even its name changed. Predatory Bureaucracy will fascinate readers interested in environmental politics and wildlife.

DOWNLOAD EBOOKThis book of photography represents National Geographic's Photo Ark, a major cross-platform initiative and lifelong project by photographer Joel Sartore to make portraits of the world's animals -- especially those that are endangered. His message: 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 prose of veteran wildlife writer Douglas Chadwick, this book presents an argument for saving all the species of our planet.

DOWNLOAD EBOOKScientists strive to develop clear rules for naming and grouping living organisms. But taxonomy, the scientific study of biological classification and evolution, is often highly debated. Members of a species, the fundamental unit of taxonomy and evolution, share a common evolutionary history and a common evolutionary path to the future. Yet, it can be difficult to determine whether the evolutionary history or future of a population is sufficiently distinct to designate it as a unique species. A species is not a fixed entity â€" the relationship among the members of the same species is only a snapshot of a moment in time. Different populations of the same species can be in different stages in the process of species formation or dissolution. In some cases hybridization and introgression can create enormous challenges in interpreting data on genetic distinctions between groups. Hybridization is far more common in the evolutionary history of many species than previously recognized. As a result, the precise taxonomic status of an organism may be highly debated. This is the current case with the Mexican gray wolf (Canis lupus baileyi) and the red wolf (Canis rufus), and this report assesses the taxonomic status for each.

DOWNLOAD EBOOKIn Rewilding North America, Dave Foreman takes on arguably the biggest ecological threat of our time: the global extinction crisis. He not only explains the problem in clear and powerful terms, but also offers a bold, hopeful, scientifically credible, and practically achievable solution. Foreman begins by setting out the specific evidence that a mass extinction is happening and analyzes how humans are causing it. Adapting Aldo Leopold's idea of ecological wounds, he details human impacts on species survival in seven categories, including direct killing, habitat loss and fragmentation, exotic species, and climate change. Foreman describes recent discoveries in conservation biology that call for wildlands networks instead of isolated protected areas, and, reviewing the history of protected areas, shows how wildlands networks are a logical next step for the conservation movement. The final section describes specific approaches for designing such networks (based on the work of the Wildlands Project, an organization Foreman helped to found) and offers concrete and workable reforms for establishing them. The author closes with an inspiring and empowering call to action for scientists and activists alike. Rewilding North America offers both a vision and a strategy for reconnecting, restoring, and rewilding the North American continent, and is an essential guidebook for anyone concerned with the future of life on earth.

DOWNLOAD EBOOK**A Library Journal Best Book of 2015 ** **A Christian Science Monitor Top Ten Book of September** In a world dominated by people and rapid climate change, species large and small are increasingly vulnerable to extinction. In Resurrection Science, journalist M. R. O'Connor explores the extreme measures scientists are taking to try and save them, from captive breeding and genetic management to de-extinction. Paradoxically, the more we intervene to save species, the less wild they often become. In stories of sixteenth-century galleon excavations, panther-tracking in Florida swamps, ancient African rainforests, Neanderthal tool-making, and cryogenic DNA banks, O'Connor investigates the philosophical questions of an age in which we "play god" with earth's biodiversity. Each chapter in this beautifully written book focuses on a unique species--from the charismatic northern white rhinoceros to the infamous passenger pigeon--and the people entwined in the animals' fates. Incorporating natural history and evolutionary biology with conversations with eminent ethicists, O'Connor's narrative goes to the heart of the human enterprise: What should we preserve of wilderness as we hurtle toward a future in which technology is present in nearly every aspect of our lives? How can we co-exist with species when our existence and their survival appear to be pitted against one another?

DOWNLOAD EBOOKWolves are some of the world's most charismatic and controversial animals, capturing the imaginations of their friends and foes alike. Highly intelligent and adaptable, they hunt and play together in close-knit packs, sometimes roaming over hundreds of square miles in search of food. Once teetering on the brink of extinction across much of the United States and Europe, wolves have made a tremendous comeback in recent years, thanks to legal protection, changing human attitudes, and efforts to reintroduce them to suitable habitats in North America. As wolf populations have rebounded, scientific studies of them have also flourished. But there hasn't been a systematic, comprehensive overview of wolf biology since 1970. In Wolves, many of the world's leading wolf experts provide state-of-the-art coverage of just about everything you could want to know about these fascinating creatures. Individual chapters cover wolf social ecology, behavior, communication, feeding habits and hunting techniques, population dynamics, physiology and pathology, molecular genetics, evolution and taxonomy, interactions with nonhuman animals such as bears and coyotes, reintroduction, interactions with humans, and conservation and recovery efforts. The book discusses both gray and red wolves in detail and includes information about wolves around the world, from the United States and Canada to Italy, Romania, Saudi Arabia, Israel, India, and Mongolia. Wolves is also extensively illustrated with black and white photos, line drawings, maps, and fifty color plates. Unrivalled in scope and comprehensiveness, Wolves will become the definitive resource on these extraordinary animals for scientists and amateurs alike. “An excellent compilation of current knowledge, with contributions from all the main players in wolf research. . . . It is designed for a wide readership, and certainly the language and style will appeal to both scientists and lucophiles alike. . . . This is an excellent summary of current knowledge and will remain the standard reference work for a long time to come.”—Stephen Harris, New Scientist “This is the place to find almost any fact you want about wolves.”—Stephen Mills, BBC Wildlife Magazine
