Book Description
AWARDS:2006 Outstanding Academic Title, by CHOICEThe 2005 Award for Excellence in Professional and Scholarly Publishing by the Association of American Publishers (AAP) Best Reference 2005, by the Library JournalRivers of North America is an important reference for scientists, ecologists, and students studying rivers and their ecosystems. It brings together information from several regional specialists on the major river basins of North America, presented in a large-format, full-color book. The introduction covers general aspects of geology, hydrology, ecology and human impacts on rivers. This is followed by 22 chapters on the major river basins. Each chapter begins with a full-page color photograph and includes several additional photographs within the text. These chapters feature three to five rivers of the basin/region, and cover several other rivers with one-page summaries. Rivers selected for coverage include the largest, the most natural, and the most affected by human impact. This one-of-a-kind resource is professionally illustrated with maps and color photographs of the key river basins. Readers can compare one river system to another in terms of its physiography, hydrology, ecology, biodiversity, and human impacts.* Extensive treatment provides a single source of information for North America's major rivers* Regional specialists provide authoritative information on more than 200 rivers* Full-color photographs and topographical maps demonstrate the beauty, major features, and uniqueness of each river system* One-page summaries help readers quickly find key statistics and make comparisons among rivers

Book Description
The NTBS was designed to address the ecological concerns about pulp mill expansion, and to increase scientific knowledge about environmental conditions [ecology, ecosystem sustainability, water pollution and control, habitat, effect on fish and fishing, etc.] in the major river systems of the north. The study's objectives were to gather and interpret sound scientific information about the basins, develop appropriate recommendations for basin management, and communicate effectively with the public. The government response report confirms the governments' commitment to ecosystem sustainability and to pollution control in northern rivers. First Nations and Metis aboriginal [native] peoples contributed significantly to the NRBS.

Book Description
Understanding the effects of nutrients on the aquatic environment will be critical for managing industrial and municipal effluent discharges in northern Alberta rivers. One objective of this study was to identify spatial patterns of nutrient limitation in the Wapiti-Smoky and Athabasca river systems, which receive a diversity of effluent discharges including municipal sewage, agricultural runoff, and effluent from oil sands and pulp mills. Investigators conducted two experiments to accomplish this goal: identification of the interactive effects of both nutrient enrichment and grazing by aquatic insects (herbivory) on algal biomass, using nutrient diffusing substrata (NDS) downstream of the Hinton combined effluent; and using NDS to quantify large-scale patterns in algal biomass and nutrient limitation upstream and downstream of the major effluent and tributary input sources along the three rivers. NDS placed at 33 sites aided in the identification of river reaches having no nutrient limitation and those having some form of nutrient limitation.

Book Description
Report to the federal ministers of Environment and Indian & Northern Affairs, Alberta's Minister of Environmental Protection, and NWT's Minister of Renewable Resources. Summarises the main scientific findings of the Northern River Basins Study, which was established to examine the relationship between industrial, municipal, agricultural, and other development and the Peace, Athabasca, and Slave River basins. Reviews the characteristics of the northern river basins and their peoples, the organisation of the Study, and major findings in the areas of environmental overview, use of aquatic resources, traditional knowledge, flow regulation, fish distribution and habitat, nutrients, dissolved oxygen, contaminants, drinking water, ecosystem health, modelling, human health, and cumulative effects. Recommendations by the Study Board, First Nations, and scientific advisors regarding such issues as basin management, monitoring, research, public participation, and a successor organisation are then presented. Also includes a summary of opinions, suggestions, and recommendations expressed at 17 community workshops held throughout the northern river basins area.

Book Description
Discusses results from artificial stream experiments in relation to the effects of effluent stressors and nutrient enrichment on benthic algal and invertebrate communities; also compares results from autumn 1993 and 1994 to document between-year variability in the relationships between effluent additions, and effects on primary and secondary producers. Results from spring 1994 are contrasted with those from autumn 1993 and 1994 to assess the importance of seasonal changes in moderating the nutrient-contaminant effects on benthic food web interactions. The artificial stream experiments were designed to decouple the effects on the riverine food web of the potentially confounding effects of nutrients and contaminants within effluent. By comparing the effects of nutrient and effluent treatments on different trophic components of the food web, the study was able to provide a mechanistic understanding of the stimulatory and/or inhihbitory effects of pulp mill effluents on the benthic food webs of the Athabasca River.

Book Description
Lists Northern River Basins Study technical reports by issue number, subject, and geographic area studied. Subject areas used to classify the reports are: hydrology/hydraulics, nutrients/dissolved oxygen, contaminants, food chain, drinking water, other uses, traditional knowledge, and synthesis and modelling. Ten geographic divisions are used: three each for the Athabasca and Peace Rivers, and one each of the Wapiti/Smoky rivers, Peace-Athabasca Delta, Lake Athabasca, and Rivière des Rochers/Slave River.
