Available in PDF, EPUB and Kindle. Book excerpt: Our understanding of the ecology of running waters has come a long way during the past few years. From being a largely descriptive subject, with a few under tones concerned with such things as fisheries, pollution or control of blackflies, it has evolved into a discipline with hypotheses, such as the River Continuum Concept (Vannote et a/. 1980), and even a book suggesting that it offers opportunity for the testing of ecological theory (Barnes & Minshall 1983). However, perusal of the literature reveals that, although some of the very early studies were concerned with large rivers (references in Hynes 1970), the great mass of the work that has been done on running water has been on streams and small rivers, and information on larger rivers is either on such limited topics as fisheries or plankton, scattered among the journals, or not available to the general limnologist. The only exceptions are a few books in this series of publications, such as those on the Nile (Rz6ska 1976), the Volga (Morduckai Boltovskoi 1979) and the Amazon {Sioli 1984), and the recent compendium by Whitton (1984) on European rivers, among which there are a few that rate as large.

Download or read book The economics of biological invasions written by Charles Perrings, Silvana Dalmazzone, Mark Herbert Williamson and published by Edward Elgar Publishing. This book was released on 2000-08-25 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'An interesting book catering perhaps for a more specific audience. It does however provide a somewhat new view of the problems of the field of biological invasions and is worth the effort.' - Ann Sundqvist, M2 Best Books 'Once again, Charles Perrings and colleagues have broken new ground by applying economic and ecological analysis to the very real problem of biological invasions. This is path-breaking work in what promises to be a new sub-discipline within environmental economics.' - David Pearce, University College London, UK Biological invasions - the introduction of living organisms beyond their original range - are one of the main drivers of biodiversity loss. They are a major threat to human health and a source of pests and pathogens in the world's farms, forests and fisheries. The growth of international trade and travel means that more species are being introduced to more places than ever before. This book represents the first concerted effort to understand the economic causes and consequences of biological invasions. The volume discusses the theoretical and methodological issues raised by invasion, including control strategies, modelling options, and a study of the economic, institutional and policy conditions that predispose countries to biological invasions. Also included are case studies of fisheries, agricultural systems, tropical forests and protected areas affected by invasive species in locations such as the Black Sea, Australia and Africa, and an evaluation of control programmes.

Download or read book The Future of Large Dams written by Thayer Scudder and published by Routledge. This book was released on 2012-04-27 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: Viewed by some as symbols of progress and by others as inherently flawed, large dams remain one of the most contentious development issues on Earth. Building on the work of the now defunct World Commission on Dams, Thayer Scudder wades into the debate with unprecedented authority. Employing the Commission's Seven Strategic priorities, Scudder charts the 'middle way' forward by examining the impacts of large dams on ecosystems, societies and political economies. He also analyses the structure of the decision-making process for water resource development and tackles the highly contentious issue of dam-induced resettlement, illuminated by a statistical analysis of 50 cases.
