Assessing Spatial and Temporal Variation in Source Water Quality and Drinking Water Treatability Across a Gradient of Forest Harvest on Vancouver Island, BC
DownloadFall 2021
On Canada’s Pacific Coast, forestry is integral to society. Although economically important, harvesting practices may alter source waters that originate in forested watersheds through changes in suspended solids (SS) and dissolved organic matter (DOM). Each of these metrics has the potential to...

Rapid thaw-driven geomorphic change transforms fluvial, sedimentary, and biogeochemical environments in the Willow River, NT
DownloadSpring 2023
The effects of global climate change are acute in permafrost environments. In the western Canadian Arctic, permafrost degradation of ice-rich slopes is resulting in the development of thermokarst and other forms of mass wasting, which transports previously frozen materials into aquatic systems....

Seasonal patterns of mortality for boreal caribou (Rangifer tarandus caribou) in an intact environment
DownloadSpring 2020
Seasonality is an important component in shaping the dynamics that influence ecosystems, including mortality. Animals experience temporal variation in vulnerability to mortality due to interactions among environmental conditions, nutritional condition, age and life stages, and changes in their...

The role of microbial extracellular polymeric substances in psychrotolerance and geochemistry of subglacial environments
DownloadFall 2012
Extracellular polymeric substances (EPS) were investigated to determine their potential role in microbial cryotolerance in the subglacial environment. The cell surface chemistry of Hymenobacter aerophilus cells, with and without EPS, was determined using potentiometric titrations and cadmium...
