Standing between Life and Extinction available in PDF, EPUB and Kindle. North American deserts—lands of little water—have long been home to a surprising diversity of aquatic life, from fish to insects and mollusks. With European settlement, however, water extraction, resource exploitation, and invasive species set many of these native aquatic species on downward spirals. In this book, conservationists dedicated to these creatures document the history of their work, the techniques and philosophies that inform it, and the challenges and opportunities of the future. A precursor to this book, Battle Against Extinction, laid out the scope of the problem and related conservation activities through the late 1980s. Since then, many nascent conservation programs have matured, and researchers have developed new technologies, improved and refined methods, and greatly expanded our knowledge of the myriad influences on the ecology and dynamics of these species. Standing between Life and Extinction brings the story up to date. While the future for some species is more secure than thirty years ago, others are less fortunate. Calling attention not only to iconic species like the razorback sucker, Gila trout, and Devils Hole pupfish, but also to other fishes and obscure and fascinating invertebrates inhabiting intermittent aquatic habitats, this book explores the scientific, social, and political challenges of preserving these aquatic species and their habitats amid an increasingly charged political discourse and in desert regions characterized by a growing human population and rapidly changing climate.

Download and read online ebook Dodging Extinction write by Anthony D. Barnosky. This book was released on 2014-10-01. Dodging Extinction available in PDF, EPUB and Kindle. Paleobiologist Anthony D. Barnosky weaves together evidence from the deep past and the present to alert us to the looming Sixth Mass Extinction and to offer a practical, hopeful plan for avoiding it. Writing from the front lines of extinction research, Barnosky tells the overarching story of geologic and evolutionary history and how it informs the way humans inhabit, exploit, and impact Earth today. He presents compelling evidence that unless we rethink how we generate the power we use to run our global ecosystem, where we get our food, and how we make our money, we will trigger what would be the sixth great extinction on Earth, with dire consequences. Optimistic that we can change this ominous forecast if we act now, Barnosky provides clear-cut strategies to guide the planet away from global catastrophe. In many instances the necessary technology and know-how already exist and are being applied to crucial issues around human-caused climate change, feeding the worldÕs growing population, and exploiting natural resources. Deeply informed yet accessibly written, Dodging Extinction is nothing short of a guidebook for saving the planet.

This book was released on 2015-03-22. Extinction available in PDF, EPUB and Kindle. Some 250 million years ago, the earth suffered the greatest biological crisis in its history. Around 95 percent of all living species died out—a global catastrophe far greater than the dinosaurs' demise 185 million years later. How this happened remains a mystery. But there are many competing theories. Some blame huge volcanic eruptions that covered an area as large as the continental United States; others argue for sudden changes in ocean levels and chemistry, including burps of methane gas; and still others cite the impact of an extraterrestrial object, similar to what caused the dinosaurs' extinction. Extinction is a paleontological mystery story. Here, the world's foremost authority on the subject provides a fascinating overview of the evidence for and against a whole host of hypotheses concerning this cataclysmic event that unfolded at the end of the Permian. After setting the scene, Erwin introduces the suite of possible perpetrators and the types of evidence paleontologists seek. He then unveils the actual evidence--moving from China, where much of the best evidence is found; to a look at extinction in the oceans; to the extraordinary fossil animals of the Karoo Desert of South Africa. Erwin reviews the evidence for each of the hypotheses before presenting his own view of what happened. Although full recovery took tens of millions of years, this most massive of mass extinctions was a powerful creative force, setting the stage for the development of the world as we know it today. In a new preface, Douglas Erwin assesses developments in the field since the book's initial publication.
