Download or read book The Quaternary Period in the United States written by A.R. Gillespie and published by Elsevier. This book was released on 2003-12-17 with total page 595 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews advances in understanding of the past ca. two million years of Earth history - the Quaternary Period - in the United States. It begins with sections on ice and water - as glaciers, permafrost, oceans, rivers, lakes, and aquifers. Six chapters are devoted to the high-latitude Pleistocene ice sheets, to mountain glaciations of the western United States, and to permafrost studies. Other chapters discuss ice-age lakes, caves, sea-level fluctuations, and riverine landscapes. With a chapter on landscape evolution models, the book turns to essays on geologic processes. Two chapters discuss soils and their responses to climate, and wind-blown sediments. Two more describe volcanoes and earthquakes, and the use of Quaternary geology to understand the hazards they pose. The next part of the book is on plants and animals. Five chapters consider the Quaternary history of vegetation in the United States. Other chapters treat forcing functions and vegetation response at different spatial and temporal scales, the role of fire as a catalyst of vegetation change during rapid climate shifts, and the use of tree rings in inferring age and past hydroclimatic conditions. Three chapters address vertebrate paleontology and the extinctions of large mammals at the end of the last glaciation, beetle assemblages and the inferences they permit about past conditions, and the peopling of North America. A final chapter addresses the numerical modeling of Quaternary climates, and the role paleoclimatic studies and climatic modeling has in predicting future response of the Earth's climate system to the changes we have wrought.

Download or read book Once and Future Giants written by Sharon Levy and published by Oxford University Press. This book was released on 2011-03-22 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: Until about 13,000 years ago, North America was home to a menagerie of massive mammals. Mammoths, camels, and lions walked the ground that has become Wilshire Boulevard in Los Angeles and foraged on the marsh land now buried beneath Chicago's streets. Then, just as the first humans reached the Americas, these Ice Age giants vanished forever. In Once and Future Giants, science writer Sharon Levy digs through the evidence surrounding Pleistocene large animal ("megafauna") extinction events worldwide, showing that understanding this history--and our part in it--is crucial for protecting the elephants, polar bears, and other great creatures at risk today. These surviving relatives of the Ice Age beasts now face the threat of another great die-off, as our species usurps the planet's last wild places while driving a warming trend more extreme than any in mammalian history. Deftly navigating competing theories and emerging evidence, Once and Future Giants examines the extent of human influence on megafauna extinctions past and present, and explores innovative conservation efforts around the globe. The key to modern-day conservation, Levy suggests, may lie fossilized right under our feet.

Download or read book In the Light of Evolution written by National Academy of Sciences and published by National Academies Press. This book was released on 2008-12-22 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current extinction crisis is of human making, and any favorable resolution of that biodiversity crisis-among the most dire in the 4-billion-year history of Earth-will have to be initiated by mankind. Little time remains for the public, corporations, and governments to awaken to the magnitude of what is at stake. This book aims to assist that critical educational mission, synthesizing recent scientific information and ideas about threats to biodiversity in the past, present, and projected future. This is the second volume from the In the Light of Evolution series, based on a series of Arthur M. Sackler colloquia, and designed to promote the evolutionary sciences. Each installment explores evolutionary perspectives on a particular biological topic that is scientifically intriguing but also has special relevance to contemporary societal issues or challenges. Individually and collectively, the ILE series aims to interpret phenomena in various areas of biology through the lens of evolution, address some of the most intellectually engaging as well as pragmatically important societal issues of our times, and foster a greater appreciation of evolutionary biology as a consolidating foundation for the life sciences.

Download or read book The Struggle for the Land written by Paul A. Olson and published by U of Nebraska Press. This book was released on 1990-01-01 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: At an 1887 council when his people were told to learn farming in the semidesert region east of the Wind River Mountains, the Shosone chief Washakie exploded with "God damn a potato!" His instincts were all against the cultivation of semiarid land. The relationship between the buffalo hunter and the potato eater?between indigenous peoples and industrial empire?is the basic theme of the studies in The Struggle for the Land. As the editor, Paul A. Olson, points out in his introduction, the theme is as old as the biblical battle between the descendents of Nimrod, the city dweller, and of Abraham, the pastoralist. But the environmental cost of developing the world's semiarid regions is a new and urgent concern. Soil erosion, the loss of lands to dams, the pollution of once productive regions through mining, and the destruction of native food plants have everywhere decreased the quality of life for indigenous peoples, who have been forced to adopt the Western agricultural practices, property concepts, and economic institutions that created the environmental crisis. The eleven chapters in this collection look at the industrial and indigenous relationships in the lands of the North American Plains Indians, the Australian Aborigines, the Kazakhs in the USSR, the Maasai in Kenya, and several groups in southern Africa, and Alaskan and Lapp (Saami) native peoples. Representing a broad range of disciplines, including anthropology, history, ecology, and agricultural science, the contributors are John W. Bennett, Anatoly Khazanov, Russel L. Barsh, Gary C. Anders, Robson Silitshena, Peter Iverson, Patrick Morris, Annette Hamilton, J. Baird Callicott, O. Douglas Schwarz, and Solomon Bekure and Ishmael Ole Pasha. They recommend realistic solutions for the problems facing people who have essentially been disenfranchised by Western-style developmentof their native semiarid lands.

Download or read book Clovis Mammoth Butchery written by L. Adrien Hannus and published by Texas A&M University Press. This book was released on 2018-04-09 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thirteen millennia ago, in a small creek valley in western South Dakota, two mammoths perished. The mammoths, an adult and a juvenile, likely a cow and calf pair, died at the edge of an ancient pond. The Lange/Ferguson site is the earliest dated archaeological site in South Dakota and one of the few North American sites that provides evidence of a Clovis-period mammoth butchering event. In addition to the preserved remains of the two mammoths, the site yielded diagnostic Clovis weaponry—three Clovis projectile points recovered in context and stratigraphically associated with the mammoth bonebed—and flaked bone tools. The site offers a rare snapshot in time detailing early Paleoindian interactions with now-extinct megafauna nearly 13,000 years ago. In Clovis Mammoth Butchery: The Lange/Ferguson Site and Associated Bone Tool Technology, L. Adrien Hannus provides a comprehensive look at one of the few New World Clovis-era sites with in-place buried deposits exhibiting evidence for an expedient bone tool technology. Multidisciplinary investigations include paleoenvironmental and geochronological reconstructions—pollen and phytoliths, geology and geomorphology, diatoms and ostracodes, mollusks, and vertebrate paleontology—as well as taphonomic evaluations and a microwear analysis of the chipped stone tools. Clovis Mammoth Butchery offers readers a rare glimpse into a singular moment in prehistory that captures human interaction with extinct animals during a rapidly changing world for which there is no modern comparison. This book shares great insight into hunting and procurement strategies used by big game hunters during the Late Pleistocene and Early Holocene.

Available in PDF, EPUB and Kindle. Book excerpt: The past decade has witnessed a major revival in attempts to separate biodiversity signals from biases imposed by sampling and the architecture of the rock record. How large a problem this poses to our understanding of biodiversity patterns remains debatable, and new approaches are being developed to investigate this question. Here palaeobiologists with widely differing approaches and interests explore the problems of extracting reliable information on biodiversity change from an imperfect geological record. Topics covered range from the application of information-theoretic approaches that identify directional causal relationships to an in-depth study of how geological biases could influence our understanding of dinosaur evolution.
