Carbon Dynamics across Contrasting Temperate Agroecosystems: Soil Organic Matter Pools, Mycorrhizae, Water Use-efficiency, Methane and Carbon Dioxide Fluxes
DownloadSpring 2022
Perennial grain crops have been proposed as a sustainable alternative to conventional annual grain crops, since they potentially hold multiple desirable features including increased soil C sequestration and biodiversity, mitigation of greenhouse gases (GHGs), and reduction of water loss and...

Techno-economic feasibility of hybrid energy systems for small-scale space heating applications in Canada
DownloadSpring 2021
Given the large energy consumption for space heating demands in Canada, renewable energy heating systems are becoming increasingly more popular and more important for small scale applications. However, these face tough challenges for applicability in cold climate regions due to various physical...

Mathematical models of spatial population dynamics typically focus on the interplay between dispersal events and birth/death processes. However, for many animal communities, significant arrangement in space can occur on shorter timescales, where births and deaths are negligible. This phenomenon...

This thesis focuses on formulating and analyzing non linear models for microbial dynamics vis-a-vis human and environmental health. Firstly, we develop and investigate a stoichiometric organic matter decomposition model in a chemostat culture that incorporates the dynamics of grazers. This...

Effect of Biochar on Soil Microbial Communities, Nutrient Availability, and Greenhouse Gases in Short Rotation Coppice Systems of Central Alberta
DownloadFall 2015
Short rotation coppice (SRC) systems using willow (Salix spp.) grown on marginal soil, amended with biochar may represent a promising source of renewable green energy for rural communities of Alberta. The Ohaton Wood Energy project, an agroforestry site located in Camrose County, is one of...

Fugitive emissions of methane (CH4) and carbon dioxide (CO2) from a lagoon containing biosolids were continuously measured using an eddy covariance system for three months. Open Path Fourier Transform Infrared Spectrometry (OP-FTIR) was also used to quantify concentrations of methane and ammonia...
