Download or read book Vegetation history written by B. Huntley and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 808 pages. Available in PDF, EPUB and Kindle. Book excerpt: The analysis of vegetation history is one of the prime objectives for vegetation scientists. In order to understand the recent composition of local floras and plant communities a second knowledge of species com position during recent millenia is essential. With the present concern over climate changes, due to human activities, an understanding of past vegeta tion distribution becomes even more important, since the correlation between climate and vegetation can often be used to predict possible impacts to crops and forests. I was very fortunate to receive the help of Drs. Webb and Huntley to compile this volume on vegetation history. They have collated an impres sive set of papers which together give an account of the vegetation history of most of the continents during the late-Tertiary and Quaternery periods. There are, however, gaps in the coverage achieved, most notably Africa, and Asia apart from Japan. The information in this book will nonetheless certainly be used widely by vegetation scientists for the regions covered in the book and much of it has relevance to the areas not explicitly described. The authors of the individual chapters have done their best to cover recent topics of interest as well as established facts. It is intended that a separate volume will be produced in the near future covering the vegetation history of Africa and Asia. I thank the editors of It fits well into the this volume for their commendable achievement.

Download or read book Canada s Vegetation written by Geoffrey A.J. Scott and published by McGill-Queen's Press - MQUP. This book was released on 1995-01-10 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: Canada's Vegetation includes comprehensive sections on tundra, forest-tundra, boreal forest and mixed forest transition, prairie (steppe), Cordilleran environments in western North America, temperate deciduous forests, and wetlands. An overview of each ecosystem is provided, and equivalent vegetation types throughout the world are reviewed and compared with those in Canada. The integration of data on climate, soil, and vegetation in a single volume makes this an invaluable reference tool. Canada's Vegetation is sure to become a standard textbook for those in the environmental sciences.
Download or read book Changing Cold Environments written by Hugh M. French and published by John Wiley & Sons. This book was released on 2011-10-13 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: Changing Cold Environments; Implications for Global Climate Change is a comprehensive overview of the changing nature of the physical attributes of Canada's cold environments and the implications of these changes to cold environments on a global scale. The book places particular emphasis on the broader environmental science and sustainability issues that are of increasing concern to all cold regions if present global climate trends continue. Clearly structured throughout, the book focuses on those elements of Canada's cold environments that will be most affected by global climate change – namely, the tundra, sub-arctic and boreal forest regions of northern Canada, and the high mid-latitude mountains of western Canada. Implications are considered for similar environments around the world resulting in a timely text suitable for second and third year undergraduates in the environmental or earth sciences courses.
Download or read book Geocryology written by Stuart A. Harris and published by CRC Press. This book was released on 2017-09-28 with total page 903 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a general survey of Geocryology, which is the study of frozen ground called permafrost. Frozen ground is the product of cold climates as well as a variety of environmental factors. Its major characteristic is the accumulation of large quantities of ice which may exceed 90% by volume. Soil water changing to ice results in ground heaving, while thawing of this ice produces ground subsidence often accompanied by soil flowage. Permafrost is very susceptible to changes in weather and climate as well as to changes in the microenvironment. Cold weather produces contraction of the ground, resulting in cracking of the soil as well as breakup of concrete, rock, etc. Thus permafrost regions have unique landforms and processes not found in warmer lands. The book is divided into three parts. Part 1 provides an introduction to the characteristics of permafrost. Four chapters deal with its definition and characteristics, the unique processes operating there, the factors affecting it, and its general distribution. Part 2 consists of seven chapters describing the characteristic landforms unique to these areas and the processes involved in their formation. Part 3 discusses the special problems encountered by engineers in construction projects including settlements, roads and railways, the oil and gas industry, mining, and the agricultural and forest industries. The three authors represent three countries and three language groups, and together have over 120 years of experience of working in permafrost areas throughout the world. The book contains over 300 illustrations and photographs, and includes an extensive bibliography in order to introduce the interested reader to the large current literature.

This book was released on 1978 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: A 1949 drill site in the Naval Petroleum Reserve Number 4, Alaska, the Fish Creek Test Well 1, was examined in August 1977 to determine the disturbance caused by drilling activities and to analyze the response and recover of the vegetation, soils, permafrost, and surficial materials to that distrubance. The site, abandoned in 1949, is located along Camp Creek, a tributary to Fish Creek located 28 km. south of Atigaru Point and west of Nuiqsut.
