Assessing the use of δ18O-PO4 analysis for tracing source inputs and the cycling of phosphorus: Applications to the Grand River
(University of Waterloo, 2014-05-01)The use of δ18O- PO4 analysis was assessed for the Grand River, a highly impacted river in Southern Ontario that receives inputs from 30 WWTPs. Significant nutrient inputs within the watershed have led to prolific aquatic ... -
Fish feeding variability over space and time in natural and regulated boreal rivers
(University of Waterloo, 2016-09-20)Within the boreal region of Canada, river ecosystems are affected by naturally low flows in the summer months and hydropower operations, which can greatly influence the structure and function of river food webs. Few long-term ... -
Nitrous oxide and nitrate in the Grand River, Ontario: Sources, production pathways and predictability
(University of Waterloo, 2013-12-13)The increased use of synthetic nitrogen fertilizers since the early 1900s has resulted in greater food production but also problems with nitrogen pollution in freshwaters. Nitrate (NO3-) is a common pollutant in rivers and ... -
The role of submersed macrophytes in river eutrophication and biogeochemical nutrient cycling
(University of Waterloo, 2012-09-28)The goal of this work is to contribute to the understanding eutrophication in large rivers with a detailed study of the Grand River, an impacted river in highly agricultural and urbanized Southern Ontario. It focuses on ...
