In a factorial experiment mixing DOM and microbes from thermokarst ponds and lakes, we found that both DOM and microbial identity strongly influenced degradation. Lake… more Year: 2025, 2025

Abstract: <p>Increasing wildfire frequency, driven by climate change, can change the concentration andcomposition of dissolved organic matter (DOM) exported from land into receiving waters by
removing terrestrial vegetation, changing soil hydrology, and interrupting microbial degradation.
In this thesis, I tested how wildfire impacts the molecular composition and reactivity of DOM. I
compared DOM… more Year: 2024, 2024

Abstract: <p>Many communities in Canada rely on water sourced from boreal forest headwaters for their drinking water. The Boreal Shield Ecozone is highly susceptible to climate change which threatens to exacerbate the effects of natural and human-driven disturbances such as wildfire, insect infestation and harvesting on water quality. Therefore, examining source water quality in headwater catchments… more Full Text: The effects of forest disturbance on dissolved organic carbon in the Algoma region, central Ontario A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Science in the Faculty of …

Regreening degraded landscapes has been proposed to support global carbon (C) mitigation measures and protect biodiversity. One of the world's largest regreening programs in the City of Greater Sudbury, Canada has… more Full Text: The biogeochemistry of regreened forests on a mining and smelting degraded landscape A Thesis Submitted to the Committee on Graduate Studies in the Partial Fulfilment of the Requirements for the Degree of Doctor of Philosophy in the Faculty of Arts and …
