Download or read book Alaska s Changing Boreal Forest written by F. Stuart Chapin and published by Oxford University Press. This book was released on 2006-01-12 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: The boreal forest is the northern-most woodland biome, whose natural history is rooted in the influence of low temperature and high-latitude. Alaska's boreal forest is now warming as rapidly as the rest of Earth, providing an unprecedented look at how this cold-adapted, fire-prone forest adjusts to change. This volume synthesizes current understanding of the ecology of Alaska's boreal forests and describes their unique features in the context of circumpolar and global patterns. It tells how fire and climate contributed to the biome's current dynamics. As climate warms and permafrost (permanently frozen ground) thaws, the boreal forest may be on the cusp of a major change in state. The editors have gathered a remarkable set of contributors to discuss this swift environmental and biotic transformation. Their chapters cover the properties of the forest, the changes it is undergoing, and the challenges these alterations present to boreal forest managers. In the first section, the reader can absorb the geographic and historical context for understanding the boreal forest. The book then delves into the dynamics of plant and animal communities inhabiting this forest, and the biogeochemical processes that link these organisms. In the last section the authors explore landscape phenomena that operate at larger temporal and spatial scales and integrates the processes described in earlier sections. Much of the research on which this book is based results from the Bonanza Creek Long-Term Ecological Research Program. Here is a synthesis of the substantial literature on Alaska's boreal forest that should be accessible to professional ecologists, students, and the interested public.

Download or read book Dry Creek written by W. Roger Powers and published by Texas A&M University Press. This book was released on 2017-05-31 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: With cultural remains dated unequivocally to 13,000 calendar years ago, Dry Creek assumed major importance upon its excavation and study by W. Roger Powers. The site was the first to conclusively demonstrate a human presence that could be dated to the same time as the Bering Land Bridge. As Powers and his team studied the site, their work verified initial expectations. Unfortunately, the research was never fully published. Dry Creek: The Archaeology and Paleoecology of a Late Pleistocene Alaskan Hunting Camp is ready to take its rightful place in the ongoing research into the peopling of the Americas. Containing the original research, this book also updates and reconsiders Dry Creek in light of more recent discoveries and analysis.

Download or read book Ice Age People of North America written by Oregon State University. Center for the Study of the First Americans and published by Corvallis : Oregon State University Press for the Center for the Study of the First Americans. This book was released on 1999 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume provides an up-to-date summary of important new discoveries from Northeast Asia and North America that are changing perceptions about the origin of the First Americans. Even though the peopling of the Americas has been the focus of scientific investigations for more than half a century, there is still no definitive evidence that will allow specialists to say when the First Americans initially arrived or who they were. However, this in no way diminishes the significance of the many new contributions being made in the field. The nineteen papers collected here provide regional archaeological syntheses and address such topics as ice marginal dynamics, the impact of plant nutrients in glacial margins, and periglacial ecology of large mammals. The concluding chapter discusses conceptual frameworks used to explain the peopling of the Americas.

Download or read book American Beginnings written by Frederick Hadleigh West and published by University of Chicago Press. This book was released on 1996-12 with total page 620 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last Ice Age, a thousand-mile-wide land bridge connected Siberia and Alaska, creating the region known as Beringia. Over twelve thousand years ago, a procession of large mammals and the humans who hunted them crossed this bridge to America. Much of the Russian evidence for this migration has until now remained largely inaccessible to American scholars. American Beginnings brings together for the first time in one volume the most up-to-date archaeological and palaeoecological evidence on Beringia from both Russia and America. "An invaluable resource. . . . It will no doubt remain the key reference book for Beringia for many years to come."—Steven Mithen, Journal of Human Evolution "Extraordinary. The fifty-six contributors . . . represent the most prominent American and Russian researchers in the region."—Choice "Publication of this well-illustrated compendium is a great service to early American and especially Siberian Upper Paleolithic archaeology."—Nicholas Saunders, New Scientist "This is a great book . . . perhaps the greatest contribution to the archaeology of Beringia that has yet been published. . . . This is the kind of book to which archaeology should aspire."—Herbert D.G. Maschner, Antiquity

Available in PDF, EPUB and Kindle. Book excerpt: Who were the first people who came to the land bridge joining northeastern Asia to Alaska and the northwest of North America? Where did they come from? How did they organize technology, especially in the context of settlement behavior? During the Pleistocene era, the people now known as Beringians dispersed across the varied landscapes of late-glacial northeast Asia and northwest North America. The twenty chapters gathered in this volume explore, in addition to the questions posed above, how Beringians adapted in response to climate and environmental changes. They share a focus on the significance of the modern-human inhabitants of the region. By examining and analyzing lithic artifacts, geoarchaeological evidence, zooarchaeological data, and archaeological features, these studies offer important interpretations of the variability to be found in the early material culture the first Beringians. The scholars contributing to this work consider the region from Lake Baikal in the west to southern British Columbia in the east. Through a technological-organization approach, this volume permits investigation of the evolutionary process of adaptation as well as the historical processes of migration and cultural transmission. The result is a closer understanding of how humans adapted to the diverse and unique conditions of the late Pleistocene.

This book was released on 2012-12-06 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: I am pleased to present this volume of invited reviews and research case studies, produced to mark the retirement of Professor A. G. Smith - one of the leading researchers in Holocene palaeoecology. A. G. Smith took his first degree at the University of Sheffield, graduating in 1951 with a first-class honours degree in Botany. His doctorate was awarded in 1956 for a study in late-Quaternary vege tational history, based in the Sub-Department of Quaternary Research at the University of Cambridge, under the supervision of the late Sir Harry Godwin, FRS. He then researched and taught at Queen's University, Belfast, from 1954, leading the Nuffield Quaternary Research Unit there, becoming Co-Director of the Palaeoecology Laboratory from 1964. He was appointed Professor and Head of the Department of Botany (later, Plant Science) at University College, Cardiff, in 1973, and retired from the School of Pure and Applied Biology at the renamed University of Wales College, Cardiff, in August 1991. Although his principal interests have been concerned with the post-glacial environmental history of the British Isles, Professor Smith has significantly in fluenced many researchers elsewhere in their interpretation of biological and other evidence for human modification of the natural environment.

Download or read book Aeolian Dust and Dust Deposits written by Kenneth Pye and published by Elsevier. This book was released on 2015-07-14 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aeolian Dust and Dust Deposits explores the entrainment, dispersion, and deposition of aeolian dust and dust deposits, with emphasis on transport and deposition of dust derived by deflation of surface sediments and soils. Topics covered range from the mechanisms of fine-particle formation to dust sources, sinks, and rates of deposition. Dust-transporting wind systems are also discussed, along with the grain size, mineralogy, and chemical composition of aeolian dust. Comprised of nine chapters, this book begins with an overview of the general nature and significance of windborne dust as well as the importance of aeolian dust and loess. The next chapter deals with the mechanisms underlying the formation of fine particles, including glacial grinding, frost and salt weathering, and fluvial comminution. The reader is then introduced to dust entrainment, transport, and deposition, together with dust sources, sinks, and rates of deposition. Subsequent chapters focus on the implications of dust deflation, transport, and deposition; dust deposition in the oceans; and loess distribution and the thickness and morphology of loess deposits. This monograph is written primarily for research workers and advanced students in sedimentology, geomorphology, and Quaternary studies, but is also likely to be of value to soil scientists, meteorologists, planetary geologists, engineers, and others concerned with environmental management.
