Описание: Winner of the Stubbendieck Great Plains Distinguished Book Prize

America�s Great Plains once possessed one of the grandest wildlife spectacles of the world, equaled only by such places as the Serengeti, the Masai Mara, or the veld of South Africa. Pronghorn antelope, gray wolves, bison, coyotes, wild horses, and grizzly bears: less than two hundred years ago these creatures existed in such abundance that John James Audubon was moved to write, �it is impossible to describe or even conceive the vast multitudes of these animals.�

In a work that is at once a lyrical evocation of that lost splendor and a detailed natural history of these charismatic species of the historic Great Plains, veteran naturalist and outdoorsman Dan Flores draws a vivid portrait of each of these animals in their glory�and tells the harrowing story of what happened to them at the hands of market hunters and ranchers and ultimately a federal killing program in the nineteenth and twentieth centuries. The Great Plains with its wildlife intact dazzled Americans and Europeans alike, prompting numerous literary tributes. American Serengeti takes its place alongside these celebratory works, showing us the grazers and predators of the plains against the vast opalescent distances, the blue mountains shimmering on the horizon, the great rippling tracts of yellowed grasslands. Far from the empty �flyover country� of recent times, this landscape is alive with a complex ecology at least 20,000 years old�a continental patrimony whose wonders may not be entirely lost, as recent efforts hold out hope of partial restoration of these historic species.

Written by an author who has done breakthrough work on the histories of several of these animals�including bison, wild horses, and coyotes�American Serengeti is as rigorous in its research as it is intimate in its sense of wonder�the most deeply informed, closely observed view we have of the Great Plains� wild heritage.

Описание:

In this thought-provoking work, author Edward P. Weber examines the values, policies, challenges, and approaches to endangered species conservation over the past 200 years. Using primary source documents and in-depth analysis of the issues, the reference tracks the evolution of species protection and conservation in the United States, and offers a brief look at global programs in the United States and other parts of the world. The book surveys how different countries are faring in protecting their plant and animal life, and considers which guidelines and programs hold the most promise for success in the future.

Chapters compare and contrast past and present attitudes regarding endangered species and extinction and identify the influence of major organizations and individuals central to the debate over endangered species. Judiciously selected primary documents also explore the impact of species endangerment and loss on natural ecosystems--and ultimately, on humankind itself.

Описание: Lively, colorful, and skillfully made fabric “portraits” of 182 endangered species bring them to real, vibrant life. Each portrait features fascinating animal and plant facts from rescuers, scientists, conservationists, and more: where they live, what their superpowers are, why they are at risk, and how we can help. Dedicated and passionate people who work to protect endangered species share details of their roles and specialties, the planning behind conservation measures, threats to healthy habitats, and inspiring success stories. This book fosters eco-awareness and responsibility with a hopeful and positive tone, not only educating but inspiring action. A percentage of money earned by the author from the sale of this book will be donated to the Sea Turtle Conservancy and to the WILD Foundation.

Описание: Natural ecosystems provide the basic conditions without which humanity could not survive. Good and services provided by ecosystems include for example provision of food, fibre and fuel, purification of water and air, cultural and aesthetic benefits, stabilization and moderation of the Earths climate, generation and renewal of soil fertility, including nutrient cycling or maintenance of genetic resources as key inputs to crop varieties and livestock breeds, medicines, and other products. However, the ability of biological diversity to continue performing these services is seriously threatened since some species are being seriously deteriorated, and in some cases destroyed. While loss of species has always occurred as a natural phenomenon, the pace of extinction has accelerated dramatically as a result of human activity. Ecosystems are being fragmented or eliminated, and innumerable species are in decline or already extinct. This book is divided into ten chapters, which are all related to endangered species research studies.

Описание: The book provides a basic understanding and history of ivory along with a discussion and photographs of its many uses. It argues that ivory collected from elephants that die of natural causes, are culled from authorised hunts, that come from archeological sites and are recycled should be allowed to move in international trade with the proceeds going to programs to end poaching.

Описание: Coral reefs declined worldwide during the 1980s and 1990s, making them perhaps the most endangered marine ecosystem on Earth. This realization spurred John W. Tunnell Jr. and others to write a comprehensive book that would raise awareness of coral reefs and their plight. Tunnell and coeditors Ernesto A. Chávez and Kim Withers present an integrated and broad-ranging synthesis, while Mexican and U.S. experts assess the current state of these fragile systems and offer a framework for their restoration. Beginning with a history of the research done in this region, Coral Reefs of the Southern Gulf of Mexico covers the geography, geology, oceanography, ecology, and biodiversity of the thirty-eight “emergent” or platform-type coral reefs in the southern Gulf. The editors include chapters on the biota—from algae to fish—followed by a look at environmental impacts, both natural (such as hurricanes and red tides) and human (such as ship groundings and dredging). The book closes with a discussion of conservation issues, which is both descriptive and prescriptive in its assessment of what has been done and what should be done to protect and manage these vital ecosystems.
