Detecting the effects of biological invasion and subsequent control efforts on wetland ecological processes
(University of Waterloo, 2018-09-21)Meadow and emergent cattail wetland communities in eastern North America are being replaced by an invasive lineage of <i>Phragmites australis</i>. This invasion has consequences for wetland ecosystem functions; including ... -
Historical Trends in Water Quality in the Grand River, Ontario: Reconstruction of Phosphorus Loadings
(University of Waterloo, 2014-01-29)Phosphorus, a mineral nutrient, is an essential element in aquatic systems. It is only available for biological activity in the form of orthophosphate and soluble restrictive phosphate. Eutrophication, caused by nutrient ... -
Influence of a dammed reservoir on nutrient (N, P, Si) loads and ratios of the Thames River, Ontario
(University of Waterloo, 2021-01-20)The increasing frequency and severity of harmful algal blooms (HABs) in Lake Erie have been troubling developments in the past few decades. Excess loads of phosphorus (P) from the watershed are considered to be a primary ... -
Influence of Antecedent Soil Moisture and Rainfall Rate on the Leaching of Nitrate and Phosphate from Intact Monoliths of Agricultural Soil
(University of Waterloo, 2010-05-18)The export of nitrogen (N) and phosphorus (P) from agricultural catchments is a major problem worldwide. The export of these nutrients is largely driven by storm events, and the hydrologic response of catchments varies ... -
Phosphorus Legacies and Water Quality Risks: A Vulnerability-Based Framework in Southern Ontario
(University of Waterloo, 2019-12-20)Excess phosphorus (P) loading increases the frequency of harmful algal blooms (HABs), posing severe threats to drinking water security and aquatic ecosystems. Efforts to reduce the inputs of P to Canadian agricultural soils ...
