Name(s): Creator (cre): Pinder, Kieran Chris, Thesis advisor (ths): Eimers, M. C, Thesis advisor (ths): Watmough, Shaun A, Degree committee member (dgc): Dillon, Peter J, Degree granting institution (dgg): Trent University
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

Variation in the &#948;<super>15</super>N and &#948;<super>13</super>C composition of POM in the Lake Simcoe watershed

Name(s): Creator (cre): Baranowska, Kamila Anna, Thesis advisor (ths): Dillon, Peter J, Degree committee member (dgc): Winter, Jennifer G, Degree committee member (dgc): Molot, Lewis A, Degree granting institution (dgg): 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 &#948… more

A regional comparison of the structure and function of benthic macroinvertebrate communities within Precambrian Shield and St. Lawrence lowland lakes in south-central Ontario

Name(s): Creator (cre): Burke, Samantha Marie, Thesis advisor (ths): Dillon, Peter J, Degree committee member (dgc): Persaud, Anurani D, Degree committee member (dgc): Molot, Lewis A, Degree granting institution (dgg): Trent University
Abstract: <p>Benthic macroinvertebrtes (BMI) are functionally important in aquatic ecosystems; as such, knowledge of their community structure and function is critical for understanding these systems. BMI were sampled from ten lakes in each of two regions of south-central Ontario to investigate which chemical and physical variables could be shaping their community structure and function. Ten… more

Phosphorus forms and response to changes in pH in acid-sensitive soils on the Precambrian Shield

Name(s): Creator (cre): Baker, Scott Robert, Thesis advisor (ths): Watmough, Shaun A, Thesis advisor (ths): Eimers, Catherine M, Degree committee member (dgc): Dillon, Peter J, Degree granting institution (dgg): Trent University
Abstract: <p>Catchment soil acidification has been suggested as a possible mechanism for reducing phosphorus (P) loading to surface waters in North America and northern Europe, but much of the research that has been conducted regarding P immobilization in pH manipulated soils has been performed at high P concentrations (> 130 &#956;M). This study investigated how soil acidity was related to P… more
