Addressing Indigenous community concerns of lake health by assessing water quality in Constance Lake, ON and biomarker responses in freshwater mussels, Pyganodon grandis and Lampsilis siliquoidea
(2023)Constance Lake First Nation has had concerns regarding the health of a culturally significant lake, Constance Lake, for several years. There are several external stressors to this lake including urbanization and forestry, ... -
The association between watershed characteristics and mercury concentrations in fish of Northern Ontario lakes
(2014-01-22)Many landscape, limnological, and ecological factors synergistically affect the mercury cycle and subsequently influence total mercury (THg) concentrations in fish. In Chapter 1, the associations between watershed and lake ... -
Characterization of an arsenite-oxidizing caballeronia sp. soil bacterium and its mutualistic relationship with trifolium pratense for arsenic remediation
(2021)The proposed application of the mutualistic interaction between a native arsenicoxidizing soil bacteria and Trifolium pratense in Northwestern Ontario mine sites is a novel approach to remediation. This thesis studies the ... -
Diatoms as an indicator of pharmaceutical contamination in a freshwater system
(2018)Historically, microalgae have been used as bio-indicators of aquatic health and this can be seen in several studies across the world. Often at the bottom of the food chain, microalgae constitute the primary producer of ... -
Effects of macrophyte cutting on a whole lake ecosystem
(2023)Macrophytes are of significant importance to aquatic ecosystems, generating primary production in nearshore environments and providing physical structure and habitat for organisms in the littoral zone of lakes. Macrophyte ... -
The impact of golf courses on nutrient dynamics from developed areas
(2017)Proper management strategies aimed at reducing the export of excess nitrogen and phosphorus to water bodies are fundamental for resolving nutrient pollution and eutrophication. Golf courses are more intensely managed than ... -
Intra-lake and inter-lake variation in copper tolerance in Daphnia from clean and metal-contaminated lakes
(2014-01-22)The freshwater invertebrate Daphnia can persist in historically metal-contaminated lakes due to its ability to adapt to metal contamination. Since different Daphnia isolates have been shown to have varying degrees of ... -
Macrophyte Community Dynamics in Lake Simcoe’s Fringe Wetlands: Potential use as Biological Indicators of Water Quality
(2016)Indices have been developed using macrophytes and water quality parameters to detect the impact of anthropogenic disturbance on coastal wetlands of the Great Lakes, but such an index does not currently exist for Lake ... -
Phytochemical analysis of boreal forest flora of Northwestern Ontario, Canada
(2017)The following research document has been written in the format of a thesis by publication. As such, there is an introductory and concluding chapter to provide addition information and context to the scope of the study, ... -
Testate amoebae (thecamoebian) based reconstruction of Lake Simcoe fringe wetland paleoenvironments
(2014-12-12)Lake Simcoe, Ontario, Canada, a large southern Ontario glacial lake, has been affected by multiple environmental stressors throughout its history. This study uses testate amoebae paleodistribution to reconstruct the ... -
Testing British Columbia's water quality guidelines as a mixture of four important contaminants, hardness, exposure time, and species effects
(2014-12-19)Provincial water quality guidelines are established in order to prevent detrimental effects of a single toxicant from affecting the health of resident aquatic life. However, the elevation of pollutants in freshwater can ... -
Zooplankton community dynamics in the Trent Seven Waterway along Lake Simcoe and Lake Couchiching
(2017)The Trent Severn Waterway (TSW) is a 386km channel that connects Lake Ontario to Georgian Bay. There is a lack of information on the water quality in the nearshore region of the TSW specifically in regards to the planktonic ...
