Carotenoid diversity in novel Hymenobacter strains isolated from Victoria Upper Glacier, Antarctica, and implications for the evolution of microbial carotenoid biosynthesis
DownloadFall 2009
Many diverse microbes have been detected in or isolated from glaciers, including novel taxa exhibiting previously unrecognized physiological properties with significant biotechnological potential. Of 29 unique phylotypes isolated from Victoria Upper Glacier, Antarctica (VUG), 12 were related to...

Documenting a Punk Scene in Edmonton, Alberta 1979-1985: Place, Legitimacy and Belonging Articulated Through Mainstream and Independent Media
DownloadSpring 2016
This thesis explores the emergence of a punk music scene in Edmonton, utilizing archival research, participant interviews and analysis of mainstream and independent media to determine how a genre that was arguably considered a British phenomenon came to have local characteristics and...

Ice-atmosphere interactions in the Canadian high Arctic: implications for the thermo-mechanical evolution of terrestrial ice masses
DownloadFall 2009
Wohlleben, Trudy Monique Heidi
Canadian High Arctic terrestrial ice masses and the polar atmosphere evolve co-dependently, and interactions between the two systems can lead to feedbacks, positive and negative. The two primary positive cryosphere-atmosphere feedbacks are: 1) The snow/ice-albedo feedback (where area changes in...

Glacier behaviour in the Karakoram region of the greater Himalaya shows strong spatial and temporal heterogeneity and, in some areas, anomalous trends compared with glaciers elsewhere in High Asia. Knowledge of the mass balance fluctuations of Karakoram glaciers, as well as of the important...

Alpine glaciers have been retreating since the Little Ice Age, leading to exposure of foreland soils. Microorganisms are the primary below ground biological influence on nutrient cycling in recently deglaciated soil and are linked to down valley vegetation colonization. Previous studies...

Nutrient and carbon export from a tidewater glacier to the coastal ocean in the Canadian Arctic Archipelago
DownloadSpring 2021
As glaciers melt, a range of on-, in-, and under-glacier processes modify and export freshwater and sediments to the ocean. This glacial runoff may influence biological productivity in coastal ecosystems by supplying essential nutrients and labile carbon. Previous studies of glacial meltwater...

The Canadian Arctic Islands (CAI) contain the largest concentration of terrestrial ice outside of the continental ice sheets. Mass loss from this region has recently increased sharply due to above average summer temperatures. Thus, increasing the understanding of the mechanisms responsible for...

Twelve deep aquifers and 12 aquitards were defined in southwestern Saskatchewan. Four major water types were identified: Type 1 (Ca-SO4) freshwaters, found in Paleozoic aquifers; Type 2 (Na-Cl) brines, found in all aquifers; Type 3 (Na-SO4) waters, mixture of Type 1 and Type 2 waters; and Type 4...

Shifts in organic matter character and microbial community dynamics from glacier headwaters to downstream rivers in the Canadian Rocky Mountains
DownloadSpring 2023
Climate change is causing mountain glacial systems to warm rapidly, leading to increased water fluxes from these catchments and concomitant export of glacially-derived sediment and organic matter (OM). Glacial OM represents an aged, but potentially bioavailable carbon pool that is compositionally...

Microbial communities are responsible for biogeochemical processes in soils such as nutrient cycling and organic matter formation, which are essential to the establishment of vegetation and ecosystem sustainability. Phospholipid fatty acid analysis, microbial respiration and enzymatic activities...
