Abstract: <p>Long-term avian population declines, particularly for the avian insectivore guild, are a conservation concern. With widespread and continuing population trends, climate change and its negative effects on avian food resources is a plausible cross-species driver. My goal was to evaluate whether bottom-up trophic effects of climate change could be influencing avian populations. I used a… more

Abstract: <p>Understanding snowpack variability is important as it plays an imperative role in environmental, hydrologic, and atmospheric systems. Research questions related to three linked areas were investigated in this thesis: 1) scaling issues in snow hydrology, 2) forest-snowpack relationships, and 3) methods of integrating snow water equivalent (SWE) into a hydrologic model for a large,… more

Name(s): Creator (cre): LeGrand, Matthew Cody LeGros, Thesis advisor (ths): Buttle, James M, Thesis advisor (ths): Metcalfe, Robert A, Degree committee member (dgc): Lafleur, Peter M, Degree committee member (dgc): Aherne, Julian, Degree granting institution (dgg): Trent University
Abstract: <p>Water balance models calculate water storage and movement within drainage basins, a primary concern for many hydrologists. A Thornthwaite water balance model (H2OBAAS) has shown poor accuracy in predicting low flows in the Petawawa River basin in Ontario, so lake storage and winter snow processes were investigated to improve the accuracy of the model. Lake storage coefficients,… more

The significance of topographically-focused groundwater recharge during winter and spring on the Oak Ridges Moraine, southern Ontario

Name(s): Creator (cre): Greenwood, Wesley, Thesis advisor (ths): Buttle, James M, Degree committee member (dgc): Eimers, M C, Degree committee member (dgc): Lafleur, P M, Degree granting institution (dgg): Trent University
Abstract: <p>The Oak Ridges Moraine (ORM) is a key hydrogeologic feature in southern Ontario. Previous work has emphasized the importance of depression-focused recharge (DFR) for the timing and location of groundwater recharge to the ORM's aquifers. However, the significance of DFR has not been empirically demonstrated and the relative control of land cover, topography, and surficial geology on… more

Groundwater Recharge in a Managed Forest on the Oak Ridges Moraine, Southern Ontario

Name(s): Creator (cre): Bialkowski, Robert John, Thesis advisor (ths): Buttle, James M, Degree committee member (dgc): Metcalfe, Robert M, Degree committee member (dgc): Lafleur, Peter M, Degree granting institution (dgg): Trent University
Abstract: <p>Groundwater recharge was estimated and compared in two open grasslands, three mixed deciduous forest stands (100+ years in age), three young red pine plantations (27 ¨C 29 years in age) and two old red pine plantations (62 ¨C 63 years in age) on the Oak Ridges Moraine, southern Ontario, Canada. Recharge was estimated using a 1-d water balance with measured precipitation, throughfall,… more
