520 |a"Nutrient enrichment is one of the most common anthropogenic stressors of aquatic ecosystems and can alter the abundance, biomass and species diversity of epilithic, macroinvertebrate and fish communities. The Wapiti-Smoky and Athabasca River systems, Alberta, receive a diversity of point and non-point effluent discharges including municipal sewage, agricultural runoff and effluent from oil sands and pulp mills. To evaluate the effects of nutrient enrichment in the wapiti-Smoky and Athabasca rivers, we documented large scale patterns in epilithic biomass and nutrient limitation in these systems between 1993-1994 to determine whether nutrients added to the rivers by natural and man-made discharges cause deterioration of water quality"--Report summary.
