Spatial and Temporal Variations in Tree Growth, Mortality, and Biodiversity in Alberta Forests
DownloadSpring 2014
Understanding the spatial and temporal variation of tree demographic rates and biodiversity is essential for predicting the dynamics of forest ecosystems and their responses to changing environments. This thesis contributes to that understanding through modeling the long-term change in tree...

Stream Crossings in the Western Boreal Forest: Assessing Impacts and Prioritizing Restoration for Native Freshwater Fishes
DownloadFall 2015
Growing anthropogenic development in response to rising demands for natural resources is a major concern for freshwater fish, particularly in resource rich regions such as Canada’s boreal forest. Expanding networks of industrial resource roads has led to the installation of hundreds of thousands...

The Biogeography of Ground Beetles (Coleoptera: Carabidae) on the Islands of Lac la Ronge, Saskatchewan, Canada
DownloadFall 2015
Islands offer unusual opportunities for studying theoretical concepts in ecology. I studied the role of island size and isolation in structuring assemblages of ground beetles (Coleoptera: Carabidae) on the islands and adjacent mainland of Lac la Ronge, Saskatchewan, Canada. Carabid beetles were...

The effects of underplanted white spruce on understory environment and vegetation in aspen-dominated stands of the western boreal forest
DownloadSpring 2012
In the boreal forest of Alberta, Canada, underplanting white spruce (Picea glauca) in aspen (Populus tremuloides) forests attempts to address concerns about "unmixing the mixedwoods". Important ecological differences exist between mixedwood, broadleaf and conifer forests. I studied changes in...

Dromaeosaurids were small to medium sized theropod dinosaurs that diversified during the Late Cretaceous, reaching a near cosmopolitan distribution. They were diverse in morphology from the small four-winged gliders of Microraptorinae, to the bear-sized giant ‘raptors’ like Achillobator or...

The potential of forest floor transfer for the reclamation of boreal forest understory plant communities
DownloadFall 2011
We examined a direct forest floor transfer reclamation technique to establish a native boreal forest understory plant community on a reclamation site at a coal mine. Forest floor material was salvaged from an aspen-dominated (Populus tremuloides Michx.) donor forest at two depths (15 and 40 cm)...

Use of an Acoustic Location System to Understand Songbird Response to Vegetation Regeneration on Reclaimed Wellsites in the Boreal Forest of Alberta
DownloadFall 2017
Limited information exists on the recovery of different ecosystem components following reclamation of oil and gas wellsites in the boreal forest of Alberta. Songbird response to wellsite reclamation efforts in the boreal forest was previously unexamined, despite the abundance of wellsites,...

Use of Bioacoustic Technology to Evaluate Habitat Use and Road Effects on Two Anuran Amphibians in the Boreal Region of Northeastern Alberta
DownloadFall 2017
Habitat loss and fragmentation are thought to be leading causes behind local to global amphibian declines. Recent expansion of the energy sector in the western boreal forest of northeastern Alberta raises concerns for amphibians that occupy this landscape. Methods for monitoring anuran amphibians...
