Abstract: <p>Silver nanoparticles (AgNP) released into aquatic environments could threaten natural bacterial communities and ecosystem services they provide. We examined natural lake bacterioplankton communities' responses to different exposures (pulse vs chronic) and types (citrate and PVP) of AgNPs at realistic environmental conditions using a mesocosm study at the Experimental Lakes Area.

Name(s): Creator (cre): Middleton, Colleen Madeleine, Thesis advisor (ths): Frost, Paul C, Degree committee member (dgc): Sager, Eric, Degree committee member (dgc): Winter, Jennifer, Degree granting institution (dgg): Trent University
Abstract: <p>In this study, I investigate the effects of nitrogen (N) and phosphorus (P) on the nutritional stoichiometry and growth of filamentous green algae of the family Zygnemataceae in situ and ex situ. I found a mean of Carbon (C):N:P ratio of 1308:66:1 for populations growing in the Kawartha Lakes of southern Ontario during the summer of 2012. FGA stoichiometry was variable, with much of the… more
