Modeling the Impacts of Global Change on Tree Growth and Stand Density of Boreal Forests in Canada
DownloadFall 2022
Abstract Global change of environment and human activity has profoundly impacted boreal forests in structure, dynamics and function, imposing serious challenges for maintaining forest growth and yield in Canada. In this thesis, I address three questions important for understanding and predicting...

Monitoring year-to-year variability in dry mixed-grass prairie yield using multi-sensor remote sensing
DownloadFall 2012
The Normalized Difference Vegetation Index (NDVI) and harvested biomass were compared to assess rangeland productivity (above-ground green biomass or “yield”) in southern Albertan dry mixed-grass prairie. Seasonal trends during the 2009 and 2010 growing seasons were investigated using harvested...

A process model was developed to determine the net energy ratio (NER) for both regular and steam-pretreated pellet production from ligno-cellulosic biomass. NER is a ratio of the net energy output to the total net energy input from non-renewable energy source into the system. Scenarios were...

This study experimentally evaluated wheat straw slurry pipelines. Tests were conducted to determine the particle properties of the biomass mixed in water over time. The saturated particle density of 1,060kg/m3 was reached after 24 hours, while the saturated moisture contents of 78.5% and 79.5%...

Fall 2011
The overall objective of this study is to develop techno-economic models for the assessment of power generation cost and optimum power plant size using forest residues as feedstock in Alberta. At the optimum size of the plant, the cost of generation of power is minimum. In this research two...

Productivity and carbon accumulation potential of transferred biofilms in reclaimed oil sands-affected wetlands
DownloadSpring 2011
Biofilms are significant contributors to primary production, nutrient cycling, bio-stabilization and the food web of wetland ecosystems. Photoautotrophic biomass (PB) and primary production (PP) were determined for biofilms exposed to various treatments and materials in wetlands near Fort...

Irving, B.D., Fedkenheuer, A.W., Bietz, J., Naeth, M.A., Lees, A.T.
Field sites for this study were established in 1987 shortly after the completion of construction of two pipelines in southern Alberta. The Dry Mixed Grass and Mixed Grass Ecoregions (Milo Pipeline Lateral) and the Aspen Parkland, Montane and Fescue Grassland Ecoregions (Porcupine Hills Lateral)...

Simulated Livestock Soil Compaction, Plant Defoliation and Litter Removal Effects on Extracellular Enzyme Activity and Vegetation Across a Moisture Gradient in Southern Alberta, Canada
DownloadSpring 2020
Barszczewski, Sara Janina Bodnar
Preservation of grasslands is vital for the continuation of the numerous ecosystem goods and services (EG&S) provided by these ecosystems, including forage for livestock, nutrient cycling, carbon sequestration and habitat for flora and fauna. All EG&S in grasslands are supported by microbial...
