Book Description
The ancient, boreal Eva forest forms the centerpiece in this evaluation of the time and nature of the enfironment during an interglaciation. This title brings together results of exmaination of hundreds of loess exposures, when loess faces were still frozen in gold-mining excavation, and data on the character and age of the deposits from fission-track dating of tphra, paleomagnetism of the loess, thermoluminescnece dating of loess, and radiocarbon dating by liquid scintillation. Dendrochronology studies of trees are compared to those from trees of the modern boreal forest.

Book Description
The Periglacial Environment, Fourth Edition, is an authoritative overview of the world’s cold, non-glacial environments. First published in 1976 and subsequently revised in 1996 and 2007, the text has been the international standard for nearly 40 years. The Fourth Edition continues to be a personal interpretation of the frost-induced conditions, geomorphic processes and landforms that characterize periglacial environments. Part One discusses the periglacial concept and describes the typical climates and ecosystems that are involved. Part Two describes the geocryology (permafrost science) associated with frozen ground. Part Three outlines the weathering and geomorphic processes associated with cold-climate conditions. Part Four provides insight into the periglacial environments of the Quaternary, especially the Late Pleistocene. Part Five describes some of the problems associated with human occupancy in regions that experience frozen ground and cold-climate conditions. Extensively revised and updated Written by an expert with over 50 years of field research Draws upon the author’s personal experience from Northern Canada, Alaska, Siberia, Tibet, Antarctica, Svalbard, Scandinavia, southern South America, Western Europe and eastern North America This book is an invaluable reference for advanced undergraduates in geography, geology, earth sciences and environmental sciences programs, and to resource managers and geotechnical engineers interested in cold regions.

Book Description
Geomorphology is the study of the Earth′s diverse physical land-surface features and the dynamic processes that shape these features. Examining natural and anthropogenic processes, The SAGE Handbook of Geomorphology is a comprehensive exposition of the fundamentals of geomorphology that examines form, process, and applications of the discipline. Organized into five substantive sections, the Handbook is an overview of: • Foundations and Relevance: including the nature and scope of geomorphology; the origins and development of geomorphology; the role and character of theory in geomorphology; geomorphology and environmental management; and geomorphology and society • Techniques and Approaches: including observations and experiments; geomorphological mapping; the significance of models; process and form; dating surfaces and sediment; remote sensing in geomorphology; GIS in geomorphology; biogeomorphology; human activity • Process and Environment: including the evolution of regolith; weathering; fluids, flows and fluxes; sediment transport and deposition; hill slopes; riverine environments; glacial geomorphology; periglacial environments; coastal environments; aeolian environments; tropical environments; karst and karst processes • Environmental Change: including landscape evolution and tectonics; interpreting quaternary environments; environmental change; disturbance and responses to geomorphic systems • Conclusion: including challenges and perspectives; and a concluding review The Handbook has contributions from 48 international authors and was initially organized by the International Association of Geomorphologists. This will be a much-used and much-cited reference for researchers in Geomorphology, Physical Geography and the Environmental Sciences.

Book Description
This book focuses on highlights (species mentioned, locality, geological age, stratigraphic positions, etc.) of nearly 1000 items published between 1821 and 2000, dealing with the remains of vertebrates that lived from about 2 million to 5000 years ago.

Book Description
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.
