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...

Forest floor protection during drilling pad construction and its benefits for natural regeneration of native boreal forest vegetation
DownloadSpring 2014
I tested forest floor protection techniques in the construction and reclamation of temporary drilling pads to restore native boreal canopy and understory cover. By covering and delineating the forest floor I hoped to reduce damage to the vegetative propagule bank, so clonal species such as aspen...

Spring 2024
Trembling aspen (Populus tremuloides Michx.) is a dioecious clonal tree species with broad distribution in North America. In dioecious species, sexes are predicted to perform differently, based on the principle of allocation and the energy costs associated with reproduction. Aspen reproduce...

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...

Identifying seasonal Lake Sturgeon (Acipenser fulvescens) movement patterns and habitat selection in the South Saskatchewan River Basin
DownloadFall 2016
Lake Sturgeon (Acipenser fulvescens Rafinesque 1817) have experienced population declines throughout their range. In Alberta, low density age-class distributions, irregular recruitment, critically low spawning potential ratios and other factors led to a 2007 designation of “Threatened” for this...

Impacts of a six year old pipeline right of way on Halimolobos virgata (Nutt.) O.E. Schulz (slender mouse ear cress), native dry mixedgrass prairie uplands, and wetlands
DownloadSpring 2016
Reclamation of native prairie ecosystems is of growing importance as they continue to be impacted by anthropogenic disturbances. Since European settlement, Alberta grasslands have declined by 61 %. Grasslands are agriculturally important, act as a carbon sink, and many species depend upon them....

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...

Long-Term Impacts of Severe Wildfire and Salvage Logging on Macroinvertebrate Assemblages and Food Web Structure in Rocky Mountain Headwater Streams
DownloadFall 2019
Wildfire is an important natural disturbance on forested landscapes influencing both physical and biological processes. The Lost Creek wildfire in 2003 was one of the more severe on Alberta’s eastern slopes and provided a unique opportunity to assess the long-term impacts of wildfire on northern...

Responses in butterflies to loss and fragmentation of boreal forests from in situ oil sands
DownloadSpring 2019
Anthropogenic loss and fragmentation of habitat are a threat to biodiversity, while increasing demands for energy have made the provision of fossil fuels an important source of disturbance to habitats around the globe. In Alberta, Canada, the extraction of a 142,000 km2 oil sands reserve is...

Restoration of Degraded Trail Crossings in Wet and Riparian Areas Using Balsam Poplar Cuttings, Blue Rapids Provincial Recreation Area, Alberta
DownloadSpring 2019
Protected areas are established and maintained in Alberta, Canada for the conservation and preservation of natural features and to facilitate their use and enjoyment for outdoor recreation and education. The use of off-highway vehicles (OHV) is a popular recreational activity in Alberta’s parks....
