520 |a"Spatial patterns in nutrient limitation were investigated using nutrient diffusing substrata in the Athabasca River, Alberta between October-December 1993. Laboratory and field experiments were initially performed to: 1) develop an innovative nutrient diffusing substrata (NDS) bioassay design that would be suitable for use in the Athabasca River, and 2) quantify nutrient release rates from NDS. Three related field experiments were subsequently conducted in the Athabasca River to determine spatial patterns in nutrient limitation and identify the effects of nutrient additions on epilithic and macroinvertebrate communities at four sites: upstream and downstream of the combined effluent discharge from the Town of Hinton and the Weldwood of Canada Ltd. bleached kraft pulp mill at Hinton, and upstream and downstream of the proposed discharge from the Alberta Pacific pulp mill (ALPac) located north-east of the Town of Athabasca"--Report summary.
