Arctic Ecosystems in a Changing Climate


Book Description

The arctic region is predicted to experience the earliest and most pronounced global warming response to human-induced climatic change. This book synthesizes information on the physiological ecology of arctic plants, discusses how physiological processes influence ecosystem processes, and explores how climate warming will affect arctic plants, plant communities, and ecosystem processes. - Reviews the physiological ecology of arctic plants - Explores biotic controls over community and ecosystems processes - Provides physiological bases for predicting how the Arctic will respond to global climate change




Canada's Cold Environments


Book Description

Low temperatures, wind-chill, snow, sea ice, and permafrost have been primary characteristics of Canada's northern and alpine environments during the past two million years. The evolution of Canada's cultural landscapes, the processes of settlement of rural areas, and the present interaction of Canadian industrial society with its biophysical environment are all deeply influenced, directly or indirectly, by the frigidity of the greater part of the country. The phenomenon of global warming, if it occurs, will lessen this coldness, but its impact on temperature extremes, sea ice regimes, vegetation, snow distribution, permafrost, glaciers, lakes, rivers, and mountain hazards are all the subject of intensive research -- the highlights of which are reviewed in Canada's Cold Environments. Eleven of Canada's leading geographers, geologists, and ecologists provide an authoritative yet readable scientific statement about the physical nature of Canada's coldness. They focus on the distinctive attributes of Canada's cold environments, their temporal and spatial variability, and the constraints that coldness places on human activity. The book is aimed at environmental scientists at all levels who need informed overviews of the substantive findings on a range of cold-related topics.




Earth System Responses to Global Change


Book Description

This book examines the differences and similarities in the earth system components - the ocean, atmosphere, and the land - between western portions of the northern and southern Western Hemispheres, past, present, and projected. The book carefully examines the physical and biological patterns and responses of given biomes, or ecological communities in the two regions. Special emphasis is placed on the relationship of physicial and biotic systems to biogeochemistry and the evolving biota patterns of land margins and surfaces. The text concludes with an assessment of the direct impact on humans on these biomes, giving full consideration to the land-use drivers of global change.* Integrated view of earth system processes on the west coasts of North and South America







Boreal Forests and Global Change


Book Description

Boreal forests form Earth's largest terrestrial biome. They are rich in ecosystem and landscape diversity, though characterized by relatively few plant species, as compared to other forested regions. The long term viability and sustainability of boreal forests is influenced by many factors. They are subject to interruptions at intervals by large-scale natural disturbances, and increasingly by human activities. Boreal ecosystem development is typically a slow process; hence rapid changes in the global environment may invoke complex responses. Many industrial nations border, or lie within, boreal regions, deriving much of their economic wealth and culture from the forests. The response of boreal forests to changes in the global environment - whether caused by direct human activity or by indirect changes such as the anticipated changes in climate - are therefore of considerable international interest, both for their policy implications and their scientific challenges. This book which contains almost 50 peer-reviewed papers from a world-wide group of experts assembled under the auspices of IBFRA, the International Boreal Forest Research Association, covers topics which will stimulate further research and the development of constructive policies for improved management and conservation of global boreal forest resources.







The Periglacial Environment


Book Description

The Periglacial Environment, Third Edition, provides an authoritative overview of the worldâ??s cold, non-glacial environments. Emphasis is placed upon the North American and Eurasian polar lowlands, but examples are also drawn from Antarctica, the Qinghai-Xizang (Tibet) Plateau, and the northern mid-latitudes. First published in 1976 and subsequently revised in 1996, the text has been the international standard for over 30 years. The Third Edition continues to be a personal interpretation of the frost-induced conditions, geomorphic processes, and landforms that typify periglacial environments. The text is divided into four parts. Part One discusses the periglacial concept and its interactions with geomorphology, geocryology and Quaternary science. It also outlines the range and variability of periglacial climates and the degree to which landscapes are in geomorphic equilibrium with prevailing periglacial conditions. Part Two describes present-day terrain that is either underlain by permafrost or experiencing intense frost action. The roles played by cryogenic weathering, ground ice, mass wasting, running water, wind action, snow and ice, and coastal processes are systematically analysed. Part Three summarizes evidence for the existence of periglacial conditions during the cold periods of the Pleistocene, with special reference to the mid-latitudes of Europe and North America. Part Four illustrates the geotechnical problems associated with human activity and resource development in periglacial environments, and discusses the potential impact of global climate change in the northern high latitudes. This excellent textbook is an invaluable resource for second and third year undergraduate students of Physical Geography, Geology, Environmental Science and Earth Science. The Periglacial Environment, Third Edition is also an informative reading for professionals, researchers and lecturers working and teaching in the field.
