Book Description
A top priority in climate research is obtaining broad-extent and long-term data to support analyses of historical patterns and trends, and for model development and evaluation. Along with directly measured climate data from the present and recent past, it is important to obtain estimates of long past climate variations spanning multiple centuries and millennia. Dendroclimatic Studies at the North American Tree Line presents an overview of the current state of dendroclimatology, its contributions over the past few decades, and its future potential. The material included is not useful not only to those who generate tree-ring records of past climate-dendroclimatologists, but also to users of their results-climatologists, hydrologists, ecologists and archeologists. In summary, this book: Sheds light on recent and future climate trends by assessing long term past climatic variations from tree rings Is a timely coverage of a crucial topic in climate science portraying recent warming trends which are of serious concern today Features well-reputed scientists highlighting new advanced methodologies to reconstruct past climate change Models the tree growth environmental response

Often cited as one of the most decisive campaigns in military history, the Seven Days Battles were the first campaign in which Robert E. Lee led the Army of Northern Virginia-as well as the first in which Lee and Thomas "Stonewall" Jackson worked together.

Book Description
Tree Rings and Climate deals with the principles of dendrochronology, with emphasis on tree-ring studies involving climate-related problems. This book looks at the spatial and temporal variations in tree-ring growth and how they can be used to reconstruct past climate. Factors and conditions that appear most relevant to tree-ring research are highlighted. Comprised of nine chapters, this book opens with an overview of the basic biological facts and principles of tree growth, as well as the most important terms, principles, and concepts of dendrochronology. The discussion then shifts to the basic biology governing the response of ring width to variation in climate; systematic variations in the width and cell structure of annual tree rings; and the significance of tree growth and structure to dendroclimatology. The movement of materials and internal water relations of trees are also considered, along with photosynthesis, respiration, and the climatic and environmental system. Models of the growth-climate relationships as well as the basic statistics and methods of analysis of these relationships are described. The final chapter includes a general discussion of dendroclimatographic data and presents examples of statistical models that are useful for reconstructing spatial variations in climate. This monograph will be of interest to climatologists, college students, and practitioners in fields such as botany, archaeology, hydrology, oceanography, biology, physiology, forestry, and geophysics.

Book Description
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.
