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
Explore the multiple issues that surround species declines and conservation efforts through the only reference source to examine the conflicting conservation issues of 49 endangered species. While the causes of endangerment are relatively easy to understand, the ultimate or underlying factors are often far more complex and difficult to address. An introduction to these issues and how to resolve them is provided in this unique collection of case studies of animal species that have been pushed to the brink of extinction. Each case study provides the following information: - Common name - Scientific name - Order - Family - Status - Threats - Habitat - Distribution - Natural history - Conflicting Issues - Future and Prognosis. Conservationists are increasingly recognizing that the ultimate causes of extinction are primarily socio-economic and political, yet biological approaches to recovery continue to dominate. More inclusive, interdisciplinary conservation programs are explored here to offer better prospects for managing problems and conflicts. In addition to the case studies, trends and common themes are explored to provide a comprehensive, interdisciplinary approach to conservation. Students and teachers can explore a wide variety of endangered species programs and the conflicting issues common to recovery efforts, which will enable them to evaluate conservation practice and to draw their own conclusions for improvement.

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
Crows can be found almost everywhere that people are, from tropical islands to deserts and arctic forests, from densely populated cities to suburbs and farms. Across these diverse landscapes, many species of crow are doing well: their intelligent and adaptive ways of life have allowed them to thrive amid human-driven transformations. Indeed, crows are frequently disliked for their success, seen as pests, threats, and scavengers on the detritus of human life. But among the vast variety of crows, there are also critically endangered species that are barely hanging on to existence, some of them the subjects of passionate conservation efforts. The Wake of Crows is an exploration of the entangled lives of humans and crows. Focusing on five key sites, Thom van Dooren asks how we might live well with crows in a changing world. He explores contemporary possibilities for shared life emerging in the context of ongoing processes of globalization, colonization, urbanization, and climate change. Moving among these diverse contexts, this book tells stories of extermination and extinction alongside fragile efforts to better understand and make room for other species. Grounded in the careful work of paying attention to particular crows and their people, The Wake of Crows is an effort to imagine and put into practice a multispecies ethics. In so doing, van Dooren explores some of the possibilities that still exist for living and dying well on this damaged planet.

Book Description
Research Council established the Ecosystems Panel in response to a request from the United States Global Change Research Program (USGCRP). The panel's charge included periodic reviews of the ecosystems aspects of the USGCRP, and this is the first of those reviews. It is based on information provided by the USGCRP, including Our Changing Planet (NSTC 1997 and earlier editions 1); ideas and conversations provided by participants in a workshop held in St. Michaels, Maryland, in July 1998; and the deliberations of the panel. In addition, the panel reviewed the ecosystems chapter of the NRC report Global Environmental Change: Research Pathways for the Next Decade (NRC 1999a, known as the Pathways report). The USGCRP is an interagency program established in 1989 and codified by the Global Change Research Act of 1990 (PL 101-606). The USGCRP comprises representatives of the departments of Agriculture, Commerce (National Oceanic and Atmospheric Administration and National Institute of Standards and Technology), Defense, Energy, Health and Human Services (the National Institute of Environmental Health Sciences), Interior, and State, as well as the Environmental Protection Agency, the National Aeronautics and Space Administration, the National Science Foundation, the Smithsonian Institution, the Office of Science and Technology Policy, the Office of Management and Budget, and the intelligence community (NSTC 1997). The USGCRP's research program is described in detail in Our Changing Planet (NSTC 1997, 1999). In brief, the program focuses on four major areas of earth-system science: 1) Seasonal to interannual climate variability; 2) Climate change over decades to centuries; 3) Changes in ozone, ultraviolet (UV) radiation, and atmospheric chemistry, and 4) Changes in land cover and in terrestrial and aquatic ecosystems. The fourth topic is the area in which advice was requested from the ecosystems panel. The Ecosystems Panel's charge has three parts: to provide a forum for the discussion of questions of ecosystem science of interest to scientists in and out of the federal agencies, to periodically review the ecosystem aspects of the USGCRP's research program, and to help identify general areas of ecosystem science that need additional attention, especially areas that cut across ecosystems and levels of ecological organization. In addressing the second item of its charge for this report, the panel first identified the most significant and challenging areas in ecosystem science, then used that identification as a basis to make recommendations to the USGCRP. Thus, this report is not a detailed review of the USGCRP's program, but rather an attempt to identify those areas that the panel concludes are most in need of attention by a general research program on global change. As noted in this report, some of those areas are already receiving attention by the USGCRP.

Book Description
Johne's Disease is a chronic, progressive intestinal disease caused by infection with Mycobacterium avium subspecies paratuberculosis (Map) that affects primarily ruminant animals. In recent decades there has been growing concern over the lack of effective control of this disease and questions have arisen regarding the possibility that Map infection could be a cause of some cases of Crohn's disease in humans. This report presents a broad outline of the steps that should be taken to control Johne's disease, reduce the spread of Map, and minimize effects of the disease in animals. The report also describes the weaknesses of our current research agenda and provides recommendations for a new research strategy to resolve the question of whether there is a link between Johne's and Crohn's diseases.
