Adaptation of white spruce to climatic risk environments in spring: implications for management under climate change
DownloadFall 2022
The timing of spring dormancy release and bud break in trees is an adaptive trait with potentially important management implications. Depending on how spring phenology is controlled, climate warming may disrupt the synchronization of bud break with the available growing season. Further,...

Fall 2015
Pine sawdust biochars produced at 300 and 550 °C with and without steam activation were assessed for its sorption capacity for phosphate and copper (Cu (II)) in aqueous solutions using batch sorption experiments, including isotherm and kinetic studies. This study implied that pine sawdust...

Afforestation and stand age affected soil respiration and net ecosystem productivity in hybrid poplar plantations in central Alberta, Canada
DownloadFall 2010
Afforestation and stand development can significantly affect soil respiration and net ecosystem productivity (NEP). I studied 1) the effects of afforestation on NEP by comparing cropland previously planted to barley (on a barley-barley-alfalfa-alfalfa-alfalfa rotation) and that converted to a...

Agricultural Biosolids Application: Greenhouse Gas Emissions, Nitrogen Dynamics, and Crop Productivity
DownloadFall 2021
Agricultural activities contribute greatly to greenhouse gas (GHG) emissions, accounting for 14% of the total anthropogenic emissions of GHG such as nitrous oxide (N2O), carbon dioxide (CO2), and methane (CH4). Of these GHG, N2O is the most concerning gas because of its high global warming...

Agroforestry and Biochar for Climate Change Mitigation: Carbon Storage, Soil Carbon Cycling, and Greenhouse Gas Emissions
DownloadFall 2022
Agroforestry systems (AFS) and the application of organic amendments in croplands can contribute to carbon (C) sequestration and reduction in greenhouse gas (GHG) emissions from agricultural lands. However, previously understudied differences among AFS and organic amendments may underestimate...

Species extinctions are inevitable, irreversible and a time-delayed process that is accelerating due to the warming climate and the loss of habitats worldwide. The most threatened vertebrate group in terrestrial ecosystems is amphibians. In this thesis, I assess potential range shifts and...

An Alternate Indicator System for Nutrient Supply as Part of Ecosystem Function, a Component of Reclamation Success in the Athabasca Oil Sands Region
DownloadFall 2017
Northeastern Alberta faces the challenges of reclaiming a vast area that has been disturbed my oil sands mining, cumulatively 896 km2 and increasing as of December 2013. The limited resources available for reclamation and expensive costs of undertaking the process necessitates that reclamation be...
