Download or read book Paleoshorelines and Prehistory written by Lucille Lewis Johnson and published by CRC Press. This book was released on 1991-11-12 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: Archaeologists have always been concerned with the relationship between the sites they study and the environments in which the sites are found. Since the end of the Pleistocene Era, sea levels have risen at least 120 meters, a factor that has considerable effect on many archaeological sites. Paleoshorelines and Prehistory: An Investigation of Method discusses the various processes that may affect coastal sites, or inland sites on shallow coastal plains, and presents a variety of methods that have been developed to reconstruct the shoreline at the time the sites were occupied. The focus of the chapters is on processes affecting coastal sites in the Americas, although the methods discussed are applicable to archaeologists worldwide. The book will also guide archaeologists in designing surveys to discover site locations, whether these are now inland or underwater. All archaeologists and students in archaeology and geology will find a tremendous wealth of useful information in this remarkable volume.

Available in PDF, EPUB and Kindle. Book excerpt: First published in 1985, Quaternary Environments represents the culmination of Quaternary research in the region of Baffin Island, Baffin Bay and West Greenland over a period of twenty years and it will serve as a timely and complementary balance to the paleo- oceanographic studies in the NE North Atlantic. The region of Baffin Island, Baffin Bay and West Greenland is probably the best place in the world to examine the interactions between ice, land and oceans on timescales of a few hundred to many thousands of years. Two introductory chapters outline the history of research and the physical background. In Part II the evidence for glacial erosion and deposition over the eastern Canadian Arctic is examined and the history of the Baffin Island continental shelf is described. Part III deals with the paleo- oceanography of Baffin Bay and the Labrador Sea through an examination of deep-sea cores dated by several different methods. In Part IV there is a comprehensive account of the stratigraphy of Baffin Island, Bylot Island, and West Greenland, from the Pliocene to the late Wisconsin. Part V examines the climatic effects of the past 10,000 years, considering evidence from pollen analysis, glacier fluctuations, changes of sea level and the response of early (Eskimo) man. This important volume will interest all quaternary scientists, especially those in glaciology, glacial geology, marine geology, and geomorphology.

Download or read book The Land Beyond written by Jack Ives and published by University of Alaska Press. This book was released on 2010-04-15 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geographer Jack Ives moved to Canada in 1954, and soon after he played an instrumental role in the establishment of the McGill Sub-Arctic Research Laboratory in central Labrador-Ungava. This fascinating account of his fifty-plus years living and working in the arctic is simultaneously a light-hearted, winning memoir and a call to action on the issues of environmental awareness and conservation that are inextricably intertwined with life in the north. Mixing personal impressions of key figures of the postwar scientific boom with the intellectual drama of field research, The Land Beyond is a memorable depiction of a life in science.

Available in PDF, EPUB and Kindle. Book excerpt: The George River caribou herd increased from 15,000 animals in 1958 to 700,000 in 1988 - the largest herd in the world at the time. The authors trace the fluctuations in this caribou population back to the 1700s, detail how the herd escaped extinction in the 1950s, and consider current environmental threats to its survival. In an examination of the life history and population biology of the herd, The Return of Caribou to Ungava offers a synthesis of the basic biological traits of the caribou, a new hypothesis about why they migrate, and a comparison to herd populations in North America, Scandinavia, and Russia. The authors conclude that the old maxim, "Nobody knows the way of the caribou," is no longer valid. Based on a study in which the caribou were tracked by satellite across Ungava, they find that caribou are able to navigate, even in unfamiliar habitats, and to return to their calving ground, movement that is central to the caribou's cyclical migration. The Return of Caribou to Ungava also examines whether the herd can adapt to global warming and other changing environmental realities.

This book was released on 2012-12-06 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: The synthesis presented in this volume is a direct outgrowth of our ten-year FORMAP Project (Forest Mapping Across Eastern North America from 20,000 yr B.P. to the Present). Many previous research efforts in paleoecology have used plant-fossil evidence as proxy information for primarily geologic or climatic reconstructions or as a bio stratigraphic basis for correlation of regional events. In contrast, in this book, we deal with ecological questions that require a holistic perspective that integrates the interactions of biota with their dynamically changing environments over time scales up to tens of thousands of years. In the FORMAP Project, our major research objective has been to use late-Quaternary plant-ecological data sets to evaluate long-term patterns and processes in forest de velopment. In order to accomplish this objective, we have prepared subcontinent-scale calibrations that quantitatively relate the production and dispersal of arboreal pollen to dominance in the vegetation for the major tree types of eastern North America. Quantification of pollen-vegetation relationships provides a basis for developing quan titative plant-ecological data sets that allow further ecological analysis of both individual taxa and forest communities through time. Application of these calibrations to fossil pollen records for interpreting forest history thus represents a fundamental step beyond traditional summaries based upon pollen percentages.

Download or read book The Boreal Ecosystem written by James A. Larsen and published by Elsevier. This book was released on 2013-09-03 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Boreal Ecosystem presents an overview of the state of knowledge on the boreal forest region of North America, with extensive reference to the boreal regions of Europe and Asia. Initial sections of this book deal with aspects of the floristic composition and evolutionary history of the boreal vegetation. These introduce subsequent discussions on the processes at work in vegetation, soils, and the atmosphere—in short, with the boreal forest as an ecosystem, the sum total of the influences of many closely interlaced biotic and physical factors. These include not only plant species that make up the visible vegetation but also nutrients, soil, temperature, rainfall, progression of the seasons, soil microflora, arthropods, insects, and larger animals such as marten, otter, beaver, moose, caribou, bear, and wolf, and man. All are closely linked strands in the web of life, a web apart from, yet dependent on and influencing, the raw physical environment. This book should serve as an introduction and reference source to its audience: undergraduate and graduate students in the biological and ecological disciplines, research workers in these fields as well as in related areas such as soil science, agronomy, genetics, and climatology; in short, everyone with an interest in boreal ecology.
