Effects of biodiversity and lake environment on the decomposition rates of aquatic macrophytes in the Kawartha Lakes, Ontario

Name(s): Creator (cre): Banks, Lauren K., Thesis advisor (ths): Frost, Paul C, Degree committee member (dgc): Dorken, Marcel, Degree committee member (dgc): Sager, Eric, Degree granting institution (dgg): Trent University
Abstract: <p>Decomposition of aquatic macrophytes has an important role in defining lake carbon (C) storage and nutrient dynamics. To test how diversity impacts decomposition dynamics and site-quality effects, I first examined whether the decomposition rate of aquatic macrophytes varies with species richness. Generally, I found neutral effects of mixing, with initial stoichiometry of component… more

Abstract: <p>Based on an endogenous hormone study, three cytokinin type phytohormones; benzyladenine (BA), trans-zeatin (tZ) and methylthiol trans-zeatin (MeSZ), as well as abscisic acid (ABA) were exogenously added at three concentrations (10-7, 10-6 and 10-5 M) to cultures of Chlorella vulgaris in an attempt to alter growth rate, total lipid and fatty acid yields and fatty acid profile. Growth… more

Name(s): Creator (cre): Shi, Yong Xiang, Thesis advisor (ths): Gueguen, Celine, Degree committee member (dgc): Newman, Karla, Degree committee member (dgc): Sager, Eric, Degree granting institution (dgg): Trent University
Abstract: <p>This study examines the influence of dissolved organic matter (DOM) on dissolved vanadium (V) speciation in the Churchill River and Great Slave Lake using diffusive gradients in thin film (DGT). Vanadium is commonly found in natural environments such as rivers, lakes and oceans. It regulates normal cell growth, but in excessive amounts, it can have toxic effects on human and aquatic… more

Name(s): Creator (cre): Winters, Cameron, Thesis advisor (ths): Gueguen, Celine, Degree committee member (dgc): Sager, Eric, Degree committee member (dgc): Emery, Neil, Degree granting institution (dgg): Trent University
Abstract: <p>This study assesses the ability of a unicellular protist, Euglena gracilis, to remove Cu and Ni from solution in mono- and bi-metallic systems. Living Euglena cells and non-living Euglena biomass were examined for their capacity to sorb metal ions. Adsorption isotherms were used in batch systems to describe the kinetic and equilibrium characteristics of metal removal. In living systems… more
