Download or read book Bison and People on the North American Great Plains written by Geoff Cunfer and published by Texas A&M University Press. This book was released on 2016-10-04 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: The near disappearance of the American bison in the nineteenth century is commonly understood to be the result of over-hunting, capitalist greed, and all but genocidal military policy. This interpretation remains seductive because of its simplicity; there are villains and victims in this familiar cautionary tale of the American frontier. But as this volume of groundbreaking scholarship shows, the story of the bison’s demise is actually quite nuanced. Bison and People on the North American Great Plains brings together voices from several disciplines to offer new insights on the relationship between humans and animals that approached extinction. The essays here transcend the border between the United States and Canada to provide a continental context. Contributors include historians, archaeologists, anthropologists, paleontologists, and Native American perspectives. This book explores the deep past and examines the latest knowledge on bison anatomy and physiology, how bison responded to climate change (especially drought), and early bison hunters and pre-contact trade. It also focuses on the era of European contact, in particular the arrival of the horse, and some of the first known instances of over-hunting. By the nineteenth century bison reached a “tipping point” as a result of new tanning practices, an early attempt at protective legislation, and ventures to introducing cattle as a replacement stock. The book concludes with a Lakota perspective featuring new ethnohistorical research. Bison and People on the North American Great Plains is a major contribution to environmental history, western history, and the growing field of transnational history.

Download or read book Interhemispheric Climate Linkages written by Vera Markgraf and published by Elsevier. This book was released on 2001-01-25 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a novel approach in the field of global change by presenting a comprehensive analysis of interhemispheric linkages of climate, present and past, and their effects on human societies. The ultimate goal of this interhemispheric integration is to improve our understanding of causes and mechanisms of climate change to enhance our capability in predicting future changes. Given the societal interest in global change issues this book offers a new approach for the integration of global information. It will provide a reference for professional scientists, researchers and graduate students in the fields of climatology, and the earth and environmental sciences. Chapters analyse instrumental atmospheric and oceanic data to address such phenomena as El Nino/Southern Oscillation variability and other climate anomalies such as the Pacific and North Atlantic Oscillation and polar air outbreaks A new systematic methodology is presented that allows objective and verifiable reconstruction of climate fields from sparse data Especially valuable in the context of climate proxy data

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 Second Assessment of Climate Change for the Baltic Sea Basin written by The BACC II Author Team and published by Springer. This book was released on 2015-04-03 with total page 501 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an update of the first BACC assessment, published in 2008. It offers new and updated scientific findings in regional climate research for the Baltic Sea basin. These include climate changes since the last glaciation (approx. 12,000 years ago), changes in the recent past (the last 200 years), climate projections up until 2100 using state-of-the-art regional climate models and an assessment of climate-change impacts on terrestrial, freshwater and marine ecosystems. There are dedicated new chapters on sea-level rise, coastal erosion and impacts on urban areas. A new set of chapters deals with possible causes of regional climate change along with the global effects of increased greenhouse gas concentrations, namely atmospheric aerosols and land-cover change. The evidence collected and presented in this book shows that the regional climate has already started to change and this is expected to continue. Projections of potential future climates show that the region will probably become considerably warmer and wetter in some parts, but dryer in others. Terrestrial and aquatic ecosystems have already shown adjustments to increased temperatures and are expected to undergo further changes in the near future. The BACC II Author Team consists of 141 scientists from 12 countries, covering various disciplines related to climate research and related impacts. BACC II is a project of the Baltic Earth research network and contributes to the World Climate Research Programme.
Download or read book Late Pleistocene and Holocene Environmental Change on the Olympic Peninsula Washington written by Daniel G. Gavin and published by Springer. This book was released on 2014-11-25 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study brings together decades of research on the modern natural environment of Washington's Olympic Peninsula, reviews past research on paleoenvironmental change since the Late Pleistocene, and finally presents paleoecological records of changing forest composition and fire over the last 14,000 years. The focus of this study is on the authors’ studies of five pollen records from the Olympic Peninsula. Maps and other data graphics are used extensively. Paleoecology can effectively address some of these challenges we face in understanding the biotic response to climate change and other agents of change in ecosystems. First, species responses to climate change are mediated by changing disturbance regimes. Second, biotic hotspots today suggest a long-term maintenance of diversity in an area, and researchers approach the maintenance of diversity from a wide range and angles (CITE). Mountain regions may maintain biodiversity through significant climate change in ‘refugia’: locations where components of diversity retreat to and expand from during periods of unfavorable climate (Keppel et al., 2012). Paleoecological studies can describe the context for which biodiversity persisted through time climate refugia. Third, the paleoecological approach is especially suited for long-lived organisms. For example, a tree species that may typically reach reproductive sizes only after 50 years and remain fertile for 300 years, will experience only 30 to 200 generations since colonizing a location after Holocene warming about 11,000 years ago. Thus, by summarizing community change through multiple generations and natural disturbance events, paleoecological studies can examine the resilience of ecosystems to disturbances in the past, showing how many ecosystems recover quickly while others may not (Willis et al., 2010).

Download or read book Alberta s Lower Athabasca Basin written by Brian M. Ronaghan and published by Athabasca University Press. This book was released on 2017-05-24 with total page 565 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past two decades, the oil sands region of northeastern Alberta has been the site of unprecedented levels of development. Alberta's Lower Athabasca Basin tells a fascinating story of how a catastrophic ice age flood left behind a unique landscape in the Lower Athabasca Basin, one that made deposits of bitumen available for surface mining. Less well known is the discovery that this flood also produced an environment that supported perhaps the most intensive use of boreal forest resources by prehistoric Native people yet recognized in Canada. Studies undertaken to meet the conservation requirements of the Alberta Historical Resources Act have yielded a rich and varied record of prehistoric habitation and activity in the oil sands area. Evidence from between 9,500 and 5,000 years ago—the result of several major excavations—has confirmed extensive human use of the region’s resources, while important contextual information provided by key geological and palaeoenvironmental studies has deepened our understanding of how the region’s early inhabitants interacted with the landscape. Touching on various elements of this rich environmental and archaeological record, the contributors to this volume use the evidence gained through research and compliance studies to offer new insights into human and natural history. They also examine the challenges of managing this irreplaceable heritage resource in the face of ongoing development. Contributors: Alwynne Beaudoin, Angela Younie, Brian O.K.
