Download or read book The Ecology of River Systems written by Bryan R. Davies and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 788 pages. 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.

This book was released on 2000 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Describes studies conducted as part of a program to provide baseline data of surficial materials, ice-flow history, and soil geochemistry in the Yellowknife area, aimed at augmenting the geoscience database to support mineral exploration & development. After description of the regional setting & bedrock geology of the area, information is presented on surficial sediments (till, glaciofluvial & glaciolacustrine sediments, peat), ice flow patterns, glacial history, and pebble lithology provenance.

Available in PDF, EPUB and Kindle. Book excerpt: The early chapters of the volume present data and interpretations of the geophysics of the craton and summarise, with sequential maps, the tectonic evolution of the craton. The main body of the text and accompanying plates and figures present the stratigraphy, structural history, and economic geology of specific sedimentary basins and regions. The volume concludes with a summary chapter in which the currently popular theories of cratonal tectonics are discussed and the unresolved questions are identified.

Book excerpt: This paper summarizes ongoing surficial geology studies and geochemical analyses of till & vegetation in the Yellowknife Greenstone Belt. It first describes the sampling & analytical methods used, the regional geologic setting, and the types of surficial sediments found in the study area. It then presents results regarding ice flow directions, the occurrence of gold grains in till, and soil & vegetation geochemical profiles.

This book was released on 1975-01-01 with total page 567 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study attempts to elucidate the temporal and spatial interrelationships between the barrenland Pre-Dorset peoples, climates and caribou herds in the period 1500-700 B.C. Items such as discreteness of herds and human bands, band movements and communication and differing cultural patterns as evidenced in artifacts, are discussed. All are used in the formulation of the discrete band/discrete herd relationship.

Book excerpt: First published in 2001, Barren Lands is the classic true story of the men who sought—and found—a great diamond mine on the last frontier of the far north. From a bloody 18th-century trek across the Canadian tundra to the daunting natural forces facing protagonists Chuck Fipke and Stewart Blusson as they struggle against the mighty DeBeers cartel, this is the definitive account of one of the world’s great mineral discoveries. Combining geology, science history, raw nature, and high intrigue, it is also a tale of supreme adventure, taking the reader into a magical—and now fast-vanishing—wild landscape. Now in a newly revised and updated edition.
