Book Description
Excess minerals in the diet and water of animals can have an adverse effect on animal health, consumers, and the environment. Preventing unsafe mineral exposure is a fundamental part of animal nutrition and management. At the request of the Food and Drug Administration, the National Academies convened a committee to make recommendations on animal tolerances and toxic dietary levels, updating a 1980 report on mineral tolerance in domestic animals. Based on a review of current scientific data and information, the report sets a "maximum tolerable level" (MTL) for each mineral as it applies to the diets of farm animals, poultry, and fish. The report includes an analysis of the effects of toxic levels in animal diets, and it identifies elements that pose potential human health concerns. The report recommends research that includes a better characterization of animal exposure to minerals through feedstuffs; a better understanding of the relationship between mineral concentrations in feed and water and the levels in consumer products such as meat, milk, and eggs; and more research on the maximum tolerable level of minerals for aquatic and companion animals.

Book Description
Recognizing the significant advances made in the field of animal genetics in the ten years since the first edition of "The Genetics of the Dog", this new edition of the successful 2001 book provides a comprehensive update on the subject, along with new material on topics of current and growing interest. Existing chapters on essential topics such as immunogenetics, genetics of diseases, developmental genetics and the genetics of behaviour have been fully updated, while new authors report on the latest advances in areas such as genetic diversity of dog breeds, canine genomics, olfactor.

Book Description
Part of the seven-volume series Genome Mapping and Molecular Breeding in Plants, this book covers Cereals and Millets, which provide staple food for most of the earth’s population. This book includes chapters on rice, wheat, maize, barley, oats, rye, sorghum, pearl millet, foxtail millet and finger millet. The emphasis is on advanced research on the major crops, including the model plants maize and rice, as well as on future road maps of genomic research for the less-often considered but equally deserving cereals and millets.

Book Description
Since becoming president, George W. Bush has walked away from the Kyoto Protocol, pushed for oil drilling in the Arctic National Wildlife Refuge, undermined protections for endangered species and wilderness, and retreated from his campaign pledge to regulate carbon dioxide. But the president’s agenda reaches deeper than these well-known policies. In Bush Versus the Environment, Robert Devine shows how the White House is quietly undermining the entire system of environmental safeguards that has developed over the past thirty years. The administration's tactics include: -Encouraging lawsuits against the federal government that challenge existing environmental laws, and then feebly defending the cases in court. -Ignoring science that doesn’t support the president's goals, and pressuring government scientists to produce the results the administration wants. -Using fuzzy math to overestimate the costs and underestimate the benefits of regulations that protect human health and the environment, which can lead to the elimination of much-needed rules. These are just a few of the administration’s strategies, which are being pursued beneath the radar of a public that overwhelmingly supports environmental protections. Bush Versus the Environment is a compelling and important look at one of the most important issues facing America today, one that will have consequences that last long after Bush has left office.

Book Description
Across Europe, land is constantly the subject of enormous and widely varied pressures. The land we have is shrinking in area due to numerous reasons, including those that are directly related to climate change and migration. In fact all disciplines that have responsibilities for the husbandry use, management, and administration of the land are forced to address the problems of how to plan and how to utilise this increasingly valuable resource. The papers contained within this book emerge from two symposia held in 2014 and 2015, which now have been arranged along four general themes reflecting the multi-disciplinary nature of the disciplines concerned with land. The first part is dedicated to the interpretation of key terms in their context and the dissimilar conceptual approaches in the governance of different states. It is followed by papers that identify the process of decision-taking: how to organize and co-operate. One large section addresses the identification of land pattern changes and the reason for it. The papers in the final cluster deal with the general theme of strategies and measures used to steer future evolution in land policies. The publication addresses various needs that have to be balanced: the tasks of living space in the face of societal and demographic changes, infrastructure supply, challenges of an increasingly urbanised region, food production, ‘green energy’, natural hazards, habitats and cultural landscapes protection.

Book Description
Mark Rushefsky confronts head-on the controversies surrounding federal cancer policy, within the context, however, of a balanced view of the politics and science involved. From 1976 to 1984, federal agencies such as the Consumer Product Safety Commission, the Environmental Protection Agency, the Food and Drug Administration, the Occupational Safety and Health Administration issued guidelines regulating public exposure to chemical carcinogens. These policies have engendered controversy and undergone numerous changes. Some of these are based on new scientific developments, others on new political developments. Making Cancer Policy analyzes the guidelines issued by these agencies in terms of their scientific and political environment. It addresses the issues of uncertainty in the scientific foundation of cancer policy, scientific controversies, the mixing of science and politics, and the political uses of science. This book shows just how "political" science can be.

Book Description
When one is privileged to participate long enough in a professional capacity, certain trends may be observed in the dynamics of how challenges are met or how problems are solved. Agricultural research is no exception in view of how the plant sciences have moved forward in the past 30 years. For example, the once grand but now nearly forgotten art of whole plant physiology has given way almost completely to the more sophisticated realm of molecular biology. What once was the American Society of Plant Physiologists’ is now the American Society of Plant Molecular Biology; a democratic decision to indemnify efforts to go beyond the limits of the classical science and actually begin to understand the underlying biological basis for genetic regulation of metabolic mechanisms in plants. Yet, as new technologies open windows of light on the inner workings of biological processes, one might reminisce with faint nostalgia on days long past when the artisans of plant physiology, biochemistry, analytical chemistry and other scientific disciplines ebbed and waned in prominence. No intentional reference is made here regarding Darwinism; the plant sciences always have been extremely competitive. Technology is pivotal. Those who develop and/or implement innovative concepts typically are regarded as leaders in their respective fields. Each positive incremental step helps bring recognition and the impetus to push a scientific discipline forward with timely approaches to address relevant opportunities.
