Available in PDF, EPUB and Kindle. Book excerpt: "No area of the world has been viewed by Americans with greater moral disapproval and yet less attention than southern Africa," writes Anthony Lake in the introduction to The "Tar Baby" Option. Feeling that there is much to be learned from an examination of the American response to the Rhodesian problem, he offers a detailed account of America's Southern Rhodesia policy since the Smith government's unilateral declaration of independence from Great Britain in 1965. The book provides information essential to an understanding of the American approach to the current crisis in the region. The author's use of previously undisclosed materials and interviews with U.S. foreign policymakers gives the reader an inside look not only at the Rhodesian question but also at the politics of American foreign policy.

Available in PDF, EPUB and Kindle. Book excerpt: Lange untangles the complex evolutionary lineages of mammal families, including the gomphotheres, elephant-like creatures that coexisted with humans at the end of the Pleistocene. You�ll learn about the geologic events that led to the ice ages, along with possible causes for the mass extinctions of so many species.

Available in PDF, EPUB and Kindle. Book excerpt: “An enjoyable read that provides a substantial amount of detail on the biology, ecology, and distribution of these fantastic animals . . . Highly recommended.” —Choice More than 10,000 years ago spectacularly large mammals roamed the pampas and jungles of South America. This book tells the story of these great beasts during and just after the Pleistocene, the geological epoch marked by the great ice ages. Megafauna describes the history and way of life of these animals, their comings and goings, and what befell them at the beginning of the modern era and the arrival of humans. It places these giants within the context of the other mammals then alive, describing their paleobiology—how they walked; how much they weighed; their diets, behavior, biomechanics; and the interactions among them and with their environment. It also tells the stories of the scientists who contributed to our discovery and knowledge of these transcendent creatures and the environment they inhabited. The episode known as the Great American Biotic Interchange, perhaps the most important of all natural history “experiments,” is also an important theme of the book, tracing the biotic events of both North and South America that led to the fauna and the ecosystems discussed in this book. “Collectively, this book brings attention to the discovery and natural history of ancient beasts in South America while providing a broader temporal and geographic background that allows readers to understand their evolution and potential immigration to South America.” —Quarterly Review of Biology “An excellent volume . . . This book is likely to facilitate progress in the understanding of fossil mammals from the Americas.” —Priscum

Download or read book Ice Age Cave Faunas of North America written by Blaine W. Schubert and published by Indiana University Press. This book was released on 2003-11-10 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gathers the findings of a number of studies on North American cave paleontology. Although not intended to be all-inclusive, Ice Age Cave Faunas of North America contains contributions that range from overviews of the significance of cave fossils to reports about new localities and studies of specific vertebrate groups. These essays describe how cave remains record the evolutionary patterns of organisms and their biogeography, how they can help reconstruct past ecosystems and climatic fluctuations, how they provide an important record of the evolution of modern ecosystems, and even how some of these caves contain traces of human activity. The book's eclectic nature should appeal to students, professional and amateur paleontologists, biologists, geologists, speleologists, and cavers. The contributors are Ticul Alvarez, Joaquin Arroyo-Cabrales, Christopher J. Bell, Larry L. Coats, Jennifer Glennon, Wulf Gose, Frederick Grady, Russell Wm. Graham, Timothy H. Heaton, Carmen J. Jans-Langel, Ernest L. Lundelius, Jr., H. Gregory McDonald, Jim I. Mead, Oscar J. Polaco, Blaine W. Schubert, Holmes A. Semken, Jr., and Alisa J. Winkler.

Download or read book Morphological Change in Quaternary Mammals of North America written by Robert Allen Martin and published by Cambridge University Press. This book was released on 1993-09-24 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines case studies of North American Quaternary mammalian evolution within the larger domain of modern evolutionary theory. It presents previously unpublished studies of a variety of taxa (xenarthrans, rodents, carnivores, ungulates) examined over several temporal scales, from a few thousand years during the Holocene to millions of years of late Pliocene and Pleistocene time. Different organizational levels are represented, from mosaic population variation, to a synopsis of Quaternary evolution of an entire order (Rodentia). In addition to specific case histories, the book includes purely theoretical and methodological contributions, for example, on the statistical recognition of stasis in the fossil record, new ways to calculate evolutionary rates, and the use of digital image analysis in the study of dental ontogeny. Perhaps the most important aspect of the studies reported in this book is that they span the time between the "ecological moment" and "deep time". Modern taxa can be traced back into the fossil record, and variation among extant taxa can be used as a control against which variation in the extinct ones can be understood.

Download or read book Late Cretaceous and Cenozoic Mammals of North America written by Michael O. Woodburne and published by Columbia University Press. This book was released on 2004-04-21 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book places into modern context the information by which North American mammalian paleontologists recognize, divide, calibrate, and discuss intervals of mammalian evolution known as North American Land Mammal Ages. It incorporates new information on the systematic biology of the fossil record and utilizes the many recent advances in geochronologic methods and their results. The book describes the increasingly highly resolved stratigraphy into which all available temporally significant data and applications are integrated. Extensive temporal coverage includes the Lancian part of the Late Cretaceous, and geographical coverage includes information from Mexico, an integral part of the North American fauna, past and present.
