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...

Mapping a Species-level Trophic and Non-trophic Multilayer Network of Known Interactions for Boreal Tetrapods of North America
DownloadFall 2021
Mapping trophic and non-trophic species interactions and mapping ecosystem-wide ecological networks have become important research avenues in network ecology, but until recently these two avenues have been separate endeavors. Now, a framework exists to combine multiple interaction types into...

Development of a GIS Water Table Visualization Tool (WTVT) for Determining Water Table Position in Heterogeneous Landscapes in the Boreal Plains Ecozone, Alberta
DownloadFall 2015
The Boreal Plain is currently undergoing an unprecedented rate of land use change from oil and gas extraction as well as forestry. This change needs to be managed responsibly to ensure the long term sustainability of the region, both ecologically and economically. As part of this understanding...

Water-Level Change in Boreal Lakes as an Indicator of Area Burned and Number of Ignitions in the Canadian Prairie Provinces.
DownloadSpring 2016
The relationship between water-level fluctuations of lakes and fire activity has never been elucidated in great detail. The majority of scientific research on wildfire-hydro-climate-vegetation dynamics examines patterns of traditional climatological variables such as temperature and precipitation...

Seeing the forest for the soil: topographic controls on soil carbon dynamics in the boreal mixedwood forest
DownloadFall 2018
Boreal forest soils store an estimated 272 Pg of carbon. Due to a high degree of spatial heterogeneity, there is a wide range in carbon stores in this ecosystem. Changes in topography and forest structure are important to carbon distribution, influencing the soil microclimate and the chemical...
