Analytical developments in the use of resemblance measures in community ecology and applications to boreal forest Carabidae
DownloadFall 2012
Understanding the factors influencing the distribution of species is one of the main goals of ecology. This thesis presents three contributions to better and more efficiently understand the factors defining the composition of ecological communities. First, I studied the impact of anthropogenic...

Application of LiDAR DEM Metrics to Estimate Road-stream Sediment Connectivity in Alberta Eastslopes Salmonid Habitats
DownloadFall 2019
In forest lands, through surface erosion and stream fragmentation, roads can be an important source of sediment generation and supply to streams. Disturbances on salmonid habitats and downstream values such as drinking water are considered to be one of the major concerns of road sediment...

Application of manure from cattle fed with different diets affects soil properties and greenhouse gas emissions
DownloadSpring 2019
Cattle production contributes the largest portion of livestock agricultural greenhouse gas (GHG) emissions in Canada mostly in the form of methane (CH4). Efforts to reduce CH4 emissions have led to modification of diet composition for livestock, resulting in a corresponding change in manure...

Application of Time Domain Reflectometry and Heat Pulse Methods for Quantifying Phase Change, Water Flow and Heat Transport in Frozen Soils
DownloadSpring 2015
Understanding water flow and heat transport processes in frozen/freezing soils is limited by methodologies for simultaneous, automated measurement of soil properties affecting soil water and heat flux. The major objective of this dissertation was to develop and evaluate time domain reflectometry...

Fall 2014
This dissertation describes a series of experiments that examined: 1) hydraulic responses of Populus trichocarpa x deltoides, Populus trichocarpa and Picea glauca plants to change in their surrounding environment; 2) Changes of aquaporin expression in response to such changes. In the first study,...

Are managed honey bees (Apis mellifera) altering native pollinator diversity, or their interactions with plants in Western Canadian grasslands?
DownloadSpring 2021
The grasslands region of southern Alberta, Canada, is dominated by agricultural activity, and approximately 75% of native grasslands have been lost to development. Honey bees (Apis mellifera) were introduced about a century ago, and today they are used to facilitate the pollination of crops; in...

Aspen (Populus tremuloides) root suckering as influenced by log storage, traffic-induced-root wounding, slash accumulation, and soil compaction
DownloadFall 2009
The objective of this thesis was to determine how aspen (Populus tremuloides Michx.) root systems and suckering are affected by decking area (site of log processing and storage) disturbances and seasonal timing of these disturbances. In a field study, summer-built log decks reduced regeneration...

Spring 2019
Trembling aspen (Populus tremuloides Michx.) is a common species in Canadian boreal forests. As a shade intolerant and dynamic species (i.e., stand density and structure change over time), it naturally regenerates by root suckering and grows rapidly. Aspen has a short life compared to spruce or...
