Abstract: <p>Total phosphorus (TP) concentrations have declined in many lakes and streams across south- central Ontario, Canada over the past three decades and changes have been most pronounced in wetland-dominated catchments. In this study, long-term (1980-2007) patterns in TP concentrations in streams were assessed at four wetland-dominated catchments that drain into Dickie Lake (DE) in south-… more Full Text: IMPACT OF WETLAND DISTURBANCE ON PHOSPHORUS LOADINGS TO LAKES A Thesis submitted to the Committee of Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Science in the Faculty of Arts and Science TRENT UNIVERSITY …

Abstract: <p>The purpose of this study was to quantify the variation of baseline carbon and nitrogen stable isotope signatures in the Lake Simcoe watershed and relate that variation to various physicochemical parameters. Particulate organic matter samples from 2009 and 2011 were used as representatives of baseline isotopic values. Temporal data from two offshore lake stations revealed that δ… more Full Text: ! ! ! ! ! ! ! ! ! VARIATION!IN!THE!δ15N!AND!δ13C!COMPOSITION!OF!POM!IN!THE!LAKE! SIMCOE!WATERSHED! ! ! ! ! !
