This volume represents a first attempt at holistically classifying and mapping ecological regions across all three countries of the North American continent. A common analytical methodology is used to examine North American ecology at multiple scales, from large continental ecosystems to subdivisions of these that correlate more detailed physical and biological settings with human activities on two levels of successively smaller units. The volume begins with an overview of North America from an ecological perspective, concepts of ecological regionalization. This is followed by descriptions of the 15 broad ecological regions, including information on physical and biological setting and human activities. The final section presents case studies in applications of the ecological characterization methodology to environmental issues. The appendix includes a list of common and scientific names of selected species characteristic of the ecological regions.

Few world figures can have so extra-ordinary a tale to tell of their childhood and young manhood as Mao Tse-Tung: it is a life story that belongs to a poet or a philosopher rather than a political leader, and it has already the quality of myth. But Sia-Yu's story is no myth. He was there. He and Mao were beggars.

This book has a strong theoretical focus and is unique in addressing both mortality and fertility over the full span of human history. It examines the demographic transition in the change in the human condition from high mortality and high fertility to low mortality and low fertility. It asks if fluctuating populations is a new phenomenon, or if there has long been an inherent tendency in Man to maximize survival and to control family size.

A review of the original French edition of this book in the American Journal of Sociology hailed it as "the most finished product yet to emerge from the new (Marxist) school of French urban sociology... The aim of the book is nothing less than to reconceptualize the field of urban sociology. It is carried out in two stages: a critique of the literature of urban sociology (and urbanization) and an attempt to lay the Marxist bases for a reconstructed urban sociology." The problems facing the world's cities, whether problems of development or of decay, cannot be solved until they have been diagnosed. The race riots in Detroit, the shantytowns of Paris, the financial crisis of New York must not be seen in isolation. The mushrooming cities of the third world, demolition and urban sprawl at home are located in a network of economics, social welfare and power politics, and the decisions we are called upon to make elude us in a fog of ideology. This brilliant exposition of the function of the city in social, economic and symbolic terms illuminates the creation and structuring of space by action administrative, productive and more immediately human. The interaction of environment and life-style, the complex of market forces and state policy against a background of traditional social practice is scrutinized with the aim of establishing concepts and research methods that will enable us to come to grips with the cities themselves and the way in which we view them. Castells draws on urban renewal in Paris, the English New Towns, the American megalopolis for concrete data in his empirical and theoretical investigation. In this English edition, a new Part V has been added on urban development in America. The chapters on the pobladores in Chile and the struggle of the FRAP in Quebec have been greatly extended and an Afterword traces the development of research in the past five years. -- Amazon.com.
