Patterns and causes of variation in understory plant diversity and composition in mature boreal mixedwood forest stands of western CanadaDownload
Boreal mixedwood forest stands are comprised of a mixture of small canopy patches of varying dominance by conifer (mostly white spruce (Picea glauca (Moench) Voss)) and broadleaf (mostly trembling aspen (Populus tremuloides Michx.) trees. The purpose of this work was to extend our understanding...
Characterization of Soil Spatial Heterogeneity and Improvement of Capping Materials for Oil Sands Mine ReclamationDownload
Surface mining in the Athabasca Oil Sands Region (AOSR), Alberta, Canada creates a large-scale ecosystem disturbance requiring ‘land reclamation’. Mining approvals require that land reclamation returns the sites to an equivalent land capability class, but this goal has proven challenging to...
Trace elements in berries collected near upgraders and open pit mines in the Athabasca Bituminous Sands Region (ABSR): distinguishing atmospheric dust deposition from plant uptakeDownload
Bitumen mining and upgrading operations in the Athabasca Bituminous Sands Region (ABSR) may lead to increased concentrations of trace elements in the surrounding environment. Elevated concentrations of potentially toxic trace elements could pose a risk to local indigenous communities through the...
Identifying understory diversity and resilience patterns with the depth-to-water index in boreal mixedwood forestsDownload
For the purpose of informing biodiversity conservation efforts in managed landscapes, we explored whether and how understory plant communities (abundance, diversity, composition) were related to a topographic moisture index, called depth-to-water, in the boreal mixedwood forests of northwestern...
Overstory and understory dynamics of whitebark pine (Pinus albicaulis) ecosystems of northwestern British ColumbiaDownload
Whitebark pine (Pinus albicaulis) is declining across its range due to disturbances such as mountain pine beetle and white pine blister rust. In this thesis, I assess the response and vulnerability of whitebark pine ecosystems to multiple stressors and disturbances at the northern edge of...
NURSERY FERTILIZATION AND UNDERSTORY COMPETITION AFFECT SEEDLING GROWTH IN OIL SANDS RECLAIMED SOILS IN ALBERTADownload
Revegetation in the oil sands mining areas in northern Alberta has often been difficult because of high mortality and slow growth of planted seedlings on reclaimed soils. Growth of the planted seedlings is limited by low nutrient and water availability in the soil on reclaimed sites. Management...
