500 |a"This report presents the results of an experiment conducted in artificial streams in which the growth of benthic algae was studied in relation to phosphorus and nitrogen concentrations in the water. The goal of this study is to determine whether benthic algal biomass in the upper Athabasca River is limited by the availability of phosphorus or nitrogen. This was accomplished by growing benthic algae in artificial streams (periphyton flumes) enriched with phosphorus or nitrogen to establish the type and degree of nutrient limitation. The flumes were located on-site, adjacent to the Athabasca River at Hinton."--Study perspective.
