Data from status and trends provide important long-term trend information about specific changes and places and the overall status of wetlands in the United States. The historical data base that the Service has developed through Status and Trends, provides photographic evidence of land use and wetlands extent dating back to the 1950s. This provides an accurate record to assist in future restoration efforts.--Publisher description.

Recent partisan squabbles over science in the news are indicative of a larger tendency for scientific research and practice to get entangled in major ideological divisions in the public arena. This politicization of science is deepened by the key role government funding plays in scientific research and development, the market leading position of U.S.-based science and technology firms, and controversial U.S. exports (such as genetically modified foods or hormone-injected livestock). This groundbreaking, one-volume, A-to-Z reference features 120-150 entries that explore the nexus of politics and science, both in the United States and in U.S. interactions with other nations. The essays, each by experts in their fields, examine: Health, environmental, and social/cultural issues relating to science and politics Concerns relating to government regulation and its impact on the practice of science Key historical and contemporary events that have shaped our contemporary view of how science and politics intersect Science and Politics: An A to Z Guide to Issues and Controversies is a must-have resource for researchers and students who seek to deepen their understanding of the connection between science and politics.

This open access book reviews the importance of ecological functioning within rangelands considering the complex inter-relationships of production agriculture, ecosystem services, biodiversity, and wildlife habitat. More than half of all lands worldwide, and up to 70% of the western USA, are classified as rangelands—uncultivated lands that often support grazing by domestic livestock. The rangelands of North America provide a vast array of goods and services, including significant economic benefit to local communities, while providing critical habitat for hundreds of species of fish and wildlife. This book provides compendium of recent data and synthesis from more than 100 experts in wildlife and rangeland ecology in Western North America. It provides a current and in-depth synthesis of knowledge related to wildlife ecology in rangeland ecosystems, and the tools used to manage them, to serve current and future wildlife biologists and rangeland managers in the working landscapes of the West. The book also identifies information gaps and serves as a jumping-off point for future research of wildlife in rangeland ecosystems. While the content focuses on wildlife ecology and management in rangelands of Western North America, the material has important implications for rangeland ecosystems worldwide.

Author Paul Greenberg uncovers the tragic unraveling of the nation's seafood supply--telling the surprising story of why Americans stopped eating from their own waters. In 2005, the United States imported nearly twice as much seafood as twenty years earlier. Bizarrely, during that same period, our seafood exports quadrupled. Greenberg examines New York oysters, Gulf shrimp, and Alaskan salmon to reveal how this came to be. Following the trail of environmental desecration, Greenberg comes to view the New York City oyster as a reminder of what is lost when local waters are not valued as a food source. A different kind of catastrophe threatens the Gulf of Mexico: Asian-farmed shrimp have flooded the American market. Finally, a proposed mining project could undermine the spawning grounds of the biggest wild sockeye salmon run left in the world. In his search to discover why this precious resource isn't better protected, Greenberg finds the great majority of Alaskan salmon is exported. Sockeye salmon is one of the most nutritionally dense animal proteins on the planet, yet Americans are shipping it abroad. But despite the challenges, hope abounds: many are working to break the current destructive patterns of consumption and return American catch to American tables.--From publisher description.
