Rhizosphere microbial response to predicted vegetation shifts and changes in rhizodeposition in boreal forest soils
DownloadFall 2018
The boreal forest is the single largest terrestrial store of carbon on Earth. In Canada’s boreal forest, approximately 23% of these carbon stocks are found in forest floors and 40% within mineral soils. The rhizosphere, soil under the direct influence of plant roots, is a hotspot for microbial...

Road Erosion, Sediment Delivery, and Consequence in the Simonette Watershed West-Central Alberta
DownloadSpring 2022
Gravel and dirt resource roads in the Alberta foothills are critical economic infrastructure, used to explore for, manage, and extract natural resources from this region. Resource roads are also known to add sediment to nearby streams and rivers, causing habitat stress for fish. Understanding...

Although many aspects of salinity tolerance in plants have been thoroughly researched, some of the fundamental aspects of plant water relations remain unclear. The main objective of my thesis research was to examine the role of aquaporin-mediated water transport in salinity tolerance of three...

Root oxygen deprivation (root hypoxia) in flooding-prone areas is detrimental to most terrestrial plants and results in growth reductions and mortality. Although plants widely vary in their waterlogging tolerance, our understanding of these variations is limited to the ability of some plants to...

Oxygen deprivation (hypoxia and anoxia) is an environmental stress affecting plants worldwide in many natural and man-made ecosystems. Aquaporins exhibit multiple physiological functions in challenging environments. The central role of aquaporins in plant water relations has been widely...

Role of host identity, stand composition, soil type and disturbance severity in structuring ectomycorrhizal communities in the boreal forest
DownloadSpring 2018
The symbiosis between trees and ectomycorrhizal fungi (EMF) is essential for tree establishment and survival in the boreal forest because it is a disturbance prone ecosystem characterized by long harsh winters and low nutrient mobility. Ectomycorrhizal fungal community composition can be...

Roots in reconstructed soils - how land reclamation practices affect the development of tree root systems
DownloadSpring 2018
Tree root systems are incredibly complex organs that fulfill several vital functions, the main ones being anchorage and uptake of water and mineral elements. They perform these functions in a highly complex and challenging soil environment with heterogeneously distributed soil resources, physical...

Festuca hallii (plains rough fescue), a late-seral bunchgrass and long-lived perennial, is difficult to restore once disturbed. Once dominant in grasslands throughout central Alberta, F. hallii now occurs in remnants, a result of agricultural and residential development, and oil and gas...

Runoff generation in a steep snow-dominated watershed in Alberta's southern Rocky Mountains
DownloadFall 2019
Star Creek is a snowmelt-dominated, steep mountain watershed with shallow soils, deep glacial till, and fractured sedimentary bedrock in the eastern slopes of Alberta’s Rocky Mountains. Measurements of streamflow quantity and chemistry at variable scales, water table dynamics, and precipitation...
