Book Description
The Hawaiian Crow, or 'Alala, once an inhabitant of large forested areas of Hawaii, is now found only in the wild in a relatively small area of the central Kona coast. The decline of the 'Alala is part of a larger phenomenon of reduction and extinction of forest birds throughout Polynesia that has been associated with human colonization. It is a symptom of underlying ecological problems. In this book, a committee of experts in ornithology, captive propagation, conservation biology, population genetics, and ecology analyzes existing data about the 'Alala and details its findings, conclusions, and recommendations concerning recovery efforts for this endangered bird.

Book Description
This book, while focusing on current preservation challenges posed by the Aga, or Mariana crow, also reflects the larger issues and challenges of biodiversity conservation in all oceanic island ecosystems. It evaluates causes for the continuing decline of the Aga, which exists on only the two southernmost islands in the Mariana archipelago, Guam and Rota, and reviews actions to halt or reverse the decrease. This book reminds us of the importance and challenge of preserving the unique environmental heritage of islands of the Mariana archipelago, the need for increased knowledge to restore and maintain native species and habitats, and the compelling and lasting value of extensive public education to stimulate environmentally informed public policy development.

Book Description
World human population is expected to reach upwards of 9 billion by 2050 and then level off over the next half-century. How can the transition to a stabilizing population also be a transition to sustainability? How can science and technology help to ensure that human needs are met while the planet's environment is nurtured and restored? Our Common Journey examines these momentous questions to draw strategic connections between scientific research, technological development, and societies' efforts to achieve environmentally sustainable improvements in human well being. The book argues that societies should approach sustainable development not as a destination but as an ongoing, adaptive learning process. Speaking to the next two generations, it proposes a strategy for using scientific and technical knowledge to better inform future action in the areas of fertility reduction, urban systems, agricultural production, energy and materials use, ecosystem restoration and biodiversity conservation, and suggests an approach for building a new research agenda for sustainability science. Our Common Journey documents large-scale historical currents of social and environmental change and reviews methods for "what if" analysis of possible future development pathways and their implications for sustainability. The book also identifies the greatest threats to sustainabilityâ€"in areas such as human settlements, agriculture, industry, and energyâ€"and explores the most promising opportunities for circumventing or mitigating these threats. It goes on to discuss what indicators of change, from children's birth-weights to atmosphere chemistry, will be most useful in monitoring a transition to sustainability.

Book Description
The story of one woman’s remarkable work with a trio of charismatic, endangered bird species—and her discoveries about the devastating threats that imperil them. In Feather Trails, wildlife biologist and birder Sophie A. H. Osborn reveals how the harmful environmental choices we’ve made—including pesticide use, the introduction of invasive species, lead poisoning, and habitat destruction—have decimated Peregrine Falcons, Hawaiian Crows, and California Condors. In the Rocky Mountains, the cloud forests of Hawai’i, and the Grand Canyon, Sophie and her colleagues work day-to-day to try to reintroduce these birds to the wild, even when it seems that the odds are steeply stacked against their survival. With humor and suspense, Feather Trails introduces us to the fascinating behaviors and unique personalities of Sophie’s avian charges and shows that what endangers them ultimately threatens all life on our planet. More than a deeply researched environmental investigation, Feather Trails is also a personal journey and human story, in which Sophie overcomes her own obstacles—among them heat exhaustion, poachers, rattlesnakes, and chauvinism. Ultimately, Feather Trails is an inspiring, poignant narrative about endangered birds and how our choices can help to ensure a future not only for the rarest species, but for us too. "An intimate look at the wonder and effort needed for working with endangered species in the wild. [Osborn's] matter-of-fact writing style and wry humor make the reader part of the action."—Booklist (starred review)

Book Description
**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?

Book Description
Annotation In this mesmerizing series of interviews with dedicated people who work to save endangered species throughout the world, an alarming truth emerges: the obstacles of human politics, greed, corruption, folly, and hypocrisy can present as much danger to a species' survival as biological causes. The dramatic lessons of this book shed new light on the problems of declining species and offer hope that we may yet change their fate.

Book Description
Will the 'Alala ever return to the wild? A bird sacred to Hawaiians and a member of the raven family, the 'Alala today survives only in captivity. How the species once flourished, how it has been driven to near-extinction, and how people struggled to save it, is the gripping story of Seeking the Sacred Raven. For years, author Mark Jerome Walters has tracked the sacred bird's role in Hawaiian culture and the indomitable 'Alala's sad decline. Trekking through Hawaii's rain forests high on Mauna Loa, talking with biologists, landowners, and government officials, he has woven an epic tale of missed opportunities and the best intentions gone awry. A species that once numbered in the thousands is now limited to about 50 captive birds. Seeking the Sacred Raven is as much about people and culture as it is about failed policies. From the ancient Polynesians who first settled the island, to Captain Cook in the 18th century, to would-be saviors of the 'Alala in the 1990s, individuals with conflicting passions and priorities have shaped Hawaii and the fate of this dwindling cloud-forest species. Walters captures brilliantly the internecine politics among private landowners, scientists, environmental groups, individuals and government agencies battling over the bird's habitat and protection. It's only one species, only one bird, but Seeking the Sacred Raven illustrates vividly the many dimensions of species loss, for the human as well as non-human world.

Book Description
“Crows and people share similar traits and social strategies. To a surprising extent, to know the crow is to know ourselves.”—from the Preface From the cave walls at Lascaux to the last painting by Van Gogh, from the works of Shakespeare to those of Mark Twain, there is clear evidence that crows and ravens influence human culture. Yet this influence is not unidirectional, say the authors of this fascinating book: people profoundly influence crow culture, ecology, and evolution as well. John Marzluff and Tony Angell examine the often surprising ways that crows and humans interact. The authors contend that those interactions reflect a process of “cultural coevolution.” They offer a challenging new view of the human-crow dynamic—a view that may change our thinking not only about crows but also about ourselves. Featuring more than 100 original drawings, the book takes a close look at the influences people have had on the lives of crows throughout history and at the significant ways crows have altered human lives. In the Company of Crows and Ravens illuminates the entwined histories of crows and people and concludes with an intriguing discussion of the crow-human relationship and how our attitudes toward crows may affect our cultural trajectory.

Book Description
The Endangered Species Act (ESA) is a far-reaching law that has sparked intense controversies over the use of public lands, the rights of property owners, and economic versus environmental benefits. In this volume a distinguished committee focuses on the science underlying the ESA and offers recommendations for making the act more effective. The committee provides an overview of what scientists know about extinctionâ€"and what this understanding means to implementation of the ESA. Habitatâ€"its destruction, conservation, and fundamental importance to the ESAâ€"is explored in detail. The book analyzes: Concepts of speciesâ€"how the term "species" arose and how it has been interpreted for purposes of the ESA. Conflicts between species when individual species are identified for protection, including several case studies. Assessment of extinction risk and decisions under the ESAâ€"how these decisions can be made more effectively. The book concludes with a look beyond the Endangered Species Act and suggests additional means of biological conservation and ways to reduce conflicts. It will be useful to policymakers, regulators, scientists, natural-resource managers, industry and environmental organizations, and those interested in biological conservation.
