Abstract: <p>Muskrat populations are declining across North America. In recent decades, hybrid cattail Typha x glauca has been invading wetlands in North America. This invasion is degrading wetland habitat, leading to reduced interspersion of water and vegetation. Muskrats are wetland-obligates and their populations are positively linked to marsh interspersion. Therefore, muskrat populations may be… more

Name(s): Creator (cre): Muir, Gillian, Thesis advisor (ths): Brown, Glen, Degree committee member (dgc): Nol, Erica, Degree committee member (dgc): Metcalfe, Robert, Degree committee member (dgc): Hu, Baoxin, Degree granting institution (dgg): Trent University
Abstract: <p>The fine-scale controls of active layer dynamics in the subarctic at the southern edge of continuous permafrost are currently poorly understood. The goal of this thesis was to understand how environmental conditions associated with upland tundra heath, open graminoid fen, and palsas/peat plateaus affected active layer thermal regime in a subarctic peatland in northern Canada. Indices of… more

Assessing basin storage: A combined hydrometric and isotopic approach for streams draining the Oak Ridges Moraine, southern Ontario

Name(s): Creator (cre): Cooke, Ciara, Thesis advisor (ths): Buttle, James M., Degree committee member (dgc): Lafleur, Peter, Degree committee member (dgc): Metcalfe, Robert, Degree granting institution (dgg): Trent University
Abstract: <p>Water storage is a fundamental component of drainage basins, controlling the synchronization between precipitation input and streamflow output. The ability of a drainage basin to store water and regulate streamflow may mediate sensitivity to climate and land cover change. There is currently no agreement on the best way to quantify basin storage. This study compares results of a combined… more
