Influence of forest canopies on the deposition of methylmercury to boreal ecosystem watersheds
DownloadFall 2010
Methylmercury (MeHg) is a potent vertebrate neurotoxin and a contaminant of global concern. Increased anthropogenic emissions of mercury (Hg) to the atmosphere have led to increased bioaccumulation of MeHg in top predatory organisms such as fish, the consumption of which is the main exposure...

Mechanisms regulating Poa pratensis L. and Festuca campestris Rybd. within the foothills fescue grasslands of southern Alberta
DownloadFall 2011
Invasion of non-native species such as Poa pratensis L. has become a serious threat to the conservation of bunch grass communities including foothills fescue grasslands in Alberta, Canada. Conservation efforts are currently limited by a poor understanding of the ecological mechanisms responsible...

Identifying historical climate-growth limitations of white spruce (Picea glauca) populations across North America
DownloadSpring 2021
Climate change may cause reduced forest productivity and higher tree mortality due to water deficits that result from increased evapotranspiration. Such limitations may occur in some areas of the North American boreal forest, where precipitation is low and warming trends are high. This thesis...

Offsetting approved harmful anthropogenic impacts in the 21st century – Insights into global offsetting practices, habitat banking as an alternative offsetting mechanism and application of habitat enhancement in northern boreal lake systems
DownloadFall 2022
Land-use change via human development is a major driver of biodiversity and habitat area loss and ecosystem function impairment. To reduce these impacts, billions of dollars are spent on environmental offsets, aimed to compensate for authorized negative impacts. Studies evaluating offset project...

Habitat Use in Undisturbed Forest and the Effect of Variable Retention Harvesting on Pollinator Assemblages (Apoidea, Syrphidae) in the Boreal Forest of Alberta
DownloadSpring 2019
While pollination in agricultural areas has been well studied, pollinators in forests have received much less attention, particularly in the boreal forest. Bees, especially native bees, and hoverflies are the two most important groups of pollinators providing crucial ecological and economical...

Spring 2010
The western toad (Anaxyrus boreas, formerly Bufo boreas) is one of many amphibian species considered to be at risk of extinction (COSEWIC status is Special Concern). I examined habitat use patterns of the western toad using several methods to gain a better understanding of its habitat...

An evaluation of hitchhiker seedlings with native boreal species as a revegetation tool of industrially disturbed sites in Alberta, Canada
DownloadSpring 2020
Herbaceous forbs hitchhiked, or co-grown, with a woody species, is a solution to establish both native woody and herbaceous species at recently disturbed sites. The broad study objectives were to (1) assess the growth of fireweed hitchhiked with three deciduous woody species and one conifer over...

Nutrient distribution in sandy soils along a forest productivity gradient in the Athabasca Oil Sands Region, Alberta, Canada
DownloadFall 2016
Brunisolic soils developed on coarse textured (sandy loam to sand) deposits comprise a significant portion of the land currently being disturbed by surface mining in the Athabasca Oil Sands Region of Alberta, Canada. The goals of this study were to determine (i) how the physical properties of...

Long Term Effects of Wildfire on Permafrost Stability and Carbon Cycling in Northern Peatlands
DownloadFall 2017
Changing fire dynamics and increasing global temperatures are causing changes to the fire regime and permafrost stability in the Arctic. Models have separately predicted the widespread thawing of permafrost and increasing magnitude and intensity of wildfires over the next century. However, while...

Temporal dynamics of plant-soil feedbacks and community consequences during Bromus inermis invasion
DownloadSpring 2021
Invasive plant species often come to dominate the community where they have become introduced, posing a serious threat to plant diversity and ecosystem functions. Yet, the long-term dynamics and impacts of invasive species do not necessarily remain constant and may attenuate over time due to...
