This thesis examined the efficacy of residual forest structure for the preservation and recovery of bryophytes five to six years after partial canopy harvest in boreal mixed-wood forests of northwestern Alberta, Canada. Bryophytes were sampled in two forest types that differed in pre-harvest...

Background Localized disturbances within grasslands alter biological properties and may shift species composition. For example, rare species in established communities may become dominant in successional communities if they exhibit traits well-suited to disturbance conditions. Although the idea...

To assess the impacts of forest harvesting and fires on lentic fish assemblages in the Boreal Plains ecoregion (Alberta, Canada), we applied a reference condition approach to 37 lakes in burned, logged, or undisturbed catchments. Fish assemblages in the reference lakes were classified into two...

The investigation of mass graves involves aspects of high political, judicial, and emotional impact. Understanding how bodies held within mass graves change between the time they are deposited and the time they are discovered (the realm of forensic taphonomy) is vital for competent collection of...

Trumpeter Swans (Cygnus buccinator) were once widespread across much of North America, but after years of exploitation were reduced to near extinction. This research addressed the extent that human disturbance is affecting Trumpeter Swan breeding productivity and developed a more efficient...

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...

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...

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....

Following a peak in the number of migrants admitted to Canada via its Temporary Foreign Worker Program, the program underwent significant changes in 2014 and 2015 that will undoubtedly affect the lives of temporary foreign workers in Canada. These changes include a limitation on the length of...

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...
