Fall 2016
Humans are the major cause of forest fires in the spring in Alberta, and have resulted in major property damage in both the Flat Top Complex fires in 2011 and the Fort McMurray fire in 2016. Fire occurrence prediction (FOP) models can help predict when and where fires can be expected in order to...

Spring 2020
Grasslands cover a quarter of the planet’s terrestrial surface and constitute 70% of the world’s agricultural land area. Grasslands provide clean water, facilitate effective nutrient cycling, and provide necessary habitat and forage for livestock and wildlife. In addition, grasslands have the...

The role of microtopography in vegetation colonization and early forest development on mine reclamation sites
DownloadSpring 2023
Microsite heterogeneity is an important variable that drives biodiversity in forests. Current forest reclamation practices often do not incorporate site heterogeneity in their practices which might pose a challenge to the reclamation goals of restoring disturbed sites to resilient and sustainable...

Wildfire effects on net precipitation, streamflow regime and rainfall-runoff events in northern Rocky Mountain watersheds
DownloadFall 2022
In recent decades, severe wildfire in western North America has increased in frequency as a result of a warming climate and historical fire suppression, impacting an increasing amount of forested area. Reduced forest canopy interception and storage combined with soil water repellency and altered...

Community ecology of ants (Hymenoptera: Formicidae) in the central sand hills of Alberta, and a key to the ants of Alberta.
DownloadFall 2012
In this study I examined ant biodiversity in Alberta. Over a two-year period, 41,791 ants were captured in pitfall traps on five sand hills in central Alberta and one adjacent aspen parkland community. Using additional collections, I produced a key to the 92 species of ants known from Alberta,...

Investigating fine-scale movement patterns and comparative swimming performance of the newly identified and threatened Rocky Mountain Sculpin (Cottus sp.) across its Canadian distribution
DownloadSpring 2016
Cumulative anthropogenic impacts to the riverscape, including hydrologic alteration, have contributed to an escalated number of freshwater fish species at risk in North America. Species dispersal is an important mechanism underlying many ecological processes. Understanding the scale at which...

Factors affecting the detectability and eastern distribution of grizzly bears in Alberta, Canada
DownloadFall 2013
Effective and adaptive conservation of a species requires knowledge of trend in abundance and distribution. Monitoring species that are highly mobile, cryptic, and occurring at low densities is especially challenging. This research investigates the local factors affecting the detectability of...

Fall 2020
Oil sands mining is a significant disturbance in the Canadian boreal forest. One objective for reclamation after mining is to create a self-sustaining ecosystem, which includes establishing a native plant community. For this thesis, study one evaluates the different plant assembly mechanisms,...

Wildfires and climate change: their effects on moose (Alces alces) and white-tailed deer (Odocoileus virginianus) winter habitat in the boreal mixedwoods of Alberta, Canada
DownloadFall 2021
Understanding how species respond to wildfires and climate change is fundamental for land use management and biodiversity conservation. Wildfires provide generalist ungulates, such as moose (Alces alces) and white-tailed deer (Odocoileus virginianus), with high quantity and quality of winter...
