DOWNLOAD EBOOKThe 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.

DOWNLOAD EBOOKThe biological effects of global warming should be of concern to all thinking individuals, for warming could cause profound disruption of natural ecosystems and could threaten many species with extinction. This important book--the first to discuss in detail the consequences of global warming for ecosystems--includes commentary by distinguished scientists on many aspects of this critical problem. Experts describe responses of animals and plants to previous climate changes, interactions between various environmental components (precipitation and soil chemistry, for example), and synergisms between climate change and human activities such as deforestation. They consider many specific ecosystems, including tropical forests, the deciduous forests of eastern North America, the forests of the Pacific Northwest, Mediterranean-type ecosystems in California, arctic tundra, and arctic marine systems. Offering discussions that are both factual and speculative, the volume points the way to future investigations of the implications of global warming.

DOWNLOAD EBOOKForgotten Grasslands of the South is the study of one of the biologically richest and most endangered ecosystems in North America. In a seamless blend of science and personal observation, renowned ecologist Reed Noss explains the natural history of southern grasslands, their origin and history, and the physical determinants of grassland distribution, including ecology, soils, landform, and hydrology. In addition to offering fascinating new information about these little-studied ecosystems, Noss demonstrates how natural history is central to the practice of conservation. Although theory and experimentation have recently dominated the field of ecology, ecologists are coming to realize how these distinct approaches are not divergent but complementary, and that pursuing them together can bring greater knowledge and understanding of how the natural world works and how we can best conserve it. This long-awaited work sets a new standard for scientific literature and is essential reading for those who study and work to conserve the grasslands of the South as well as for everyone who is fascinated by the natural world.

DOWNLOAD EBOOKFrom the lush forests of Appalachia to the frozen tundra of Alaska, and from the tallgrass prairies of the Midwest to the subtropical rainforests of Hawaii, the United States harbors a remarkable array of ecosystems. These ecosystems in turn sustain an exceptional variety of plant and animal life. For species such as salamanders and freshwater turtles, the United States ranks as the global center of diversity. Among the nation's other unique biological features are California's coast redwoods, the world's tallest trees, and Nevada's Devils Hole pupfish, which survives in a single ten-by-seventy-foot desert pool, the smallest range of any vertebrate animal. Precious Heritage draws together for the first time a quarter century of information on U.S. biodiversity developed by natural heritage programs from across the country. This richly illustrated volume not only documents those aspects of U.S. biodiversity that are particularly noteworthy, but also considers how our species and ecosystems are faring, what is threatening them, and what is needed to protect the nation's remaining natural inheritance. Above all, Precious Heritage is a celebration of the extraordinary biological diversity of the United States.

DOWNLOAD EBOOKMain description: The first listed species to make headlines after the Endangered Species Act was passed in 1973 was the snail darter, a three-inch fish that stood in the way of a massive dam on the Little Tennessee River. When the Supreme Court sided with the darter, Congress changed the rules. The dam was built, the river stopped flowing, and the snail darter went extinct on the Little Tennessee, though it survived in other waterways. A young Al Gore voted for the dam; freshman congressman Newt Gingrich voted for the fish. A lot has changed since the 1970s, and Joe Roman helps us understand why we should all be happy that this sweeping law is alive and well today. More than a general history of endangered species protection, Listed is a tale of threatened species in the wild-from the whooping crane and North Atlantic right whale to the purple bankclimber, a freshwater mussel tangled up in a water war with Atlanta-and the people working to save them. Employing methods from the new field of ecological economics, Roman challenges the widely held belief that protecting biodiversity is too costly. And with engaging directness, he explains how preserving biodiversity can help economies and communities thrive. Above all, he shows why the extinction of species matters to us personally-to our health and safety, our prosperity, and our joy in nature.

DOWNLOAD EBOOKThe vast size of the United States and extensive variation of its climate, topography, and biota across different regions contribute to both the richness of the nation‘s natural heritage and the complexities involved in managing its resources. A follow-up to RFF‘s popular America‘s Renewable Resources (1990), Perspectives on Sustainable Resources in America updates readers about the current challenges involved in managing America‘s natural resources, especially in light of the increasing emphasis on sustainability and ecosystem approaches to management. Written to inform general audiences and students, as well as to engage the interest of experts, the book includes assessments by some of the nation‘s most renowned scholars in natural resource economics and policy. An introductory chapter critically examines the concept of sustainability as it has been developed in recent years and asks how the concept might apply to individual resource systems. It considers the interrelatedness of ecosystem, economic, and social sustainability; the paradigms of resource sufficiency and functional integrity; and the contrast between weak and strong sustainability. The chapters that follow examine America‘s experience with forests, water, agricultural soils, and wildlife. Highlighting the adaptability and resilience of resource systems, each chapter provides a description of the physical characteristics of the resource, a history of its use, a policy history, and a review of ongoing debates in management and policy. Perspectives on Sustainable Resources in America concludes with an innovative treatment of biodiversity as a natural resource. The chapter reviews the definitions of biodiversity, the ecological and economic meanings of biodiversity, and current efforts to preserve biodiversity, especially through regulatory approaches.

DOWNLOAD EBOOKSea otters are good indicators of ocean health. In addition, they are a keystone species, offering a stabilizing effect on ecosystem, controlling sea urchin populations that would otherwise inflict damage to kelp forest ecosystems. The kelp forest ecosystem is crucial for marine organisms and contains coastal erosion. With the concerns about the imperiled status of sea otter populations in California, Aleutian Archipelago and coastal areas of Russia and Japan, the last several years have shown growth of interest culturally and politically in the status and preservation of sea otter populations. Sea Otter Conservation brings together the vast knowledge of well-respected leaders in the field, offering insight into the more than 100 years of conservation and research that have resulted in recovery from near extinction. This publication assesses the issues influencing prospects for continued conservation and recovery of the sea otter populations and provides insight into how to handle future global changes. - Covers scientific, cultural, economic and political components of sea otter conservation - Provides guidance on how to manage threats to the sea otter populations in the face of future global changes - Highlights the effects that interactions of coastal animals have with the marine ecosystem
