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...

An Assessment of Intercropping and Fertilization in Cassava - (Manihot esculenta) Based Systems in the Kolli Hills, South India
DownloadSpring 2015
There is much interest in reducing risk, increasing yield and maintaining soil fertility and biodiversity in agriculture. The effects of intercropping cassava (M. esculenta crantz) with beans (Phaseolus spp), millet (E. coracana) or a bean-millet mixture with the use of various soil amendment...

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...

Assessing operational silviculture and modeling juvenile growth in Saskatchewan white spruce (Picea glauca (Moench) Voss) plantations
DownloadFall 2015
White spruce (Picea glauca (Moench) Voss) plantations are often established with mechanical site preparation and tending. These silvicultural treatments encourage plantation survival and can influence growth, composition, and yield. To assess operational silviculture and model managed stand...

Assessing the vulnerability of rare plants using climate change velocity, habitat connectivity and dispersal ability
DownloadFall 2015
Climate change generally requires species to migrate northward or to higher elevation to maintain constant climate conditions, but migration requirement and migration capacity of individual species can vary greatly. Individual populations of species occupy different positions in the landscape...

COARSE WOODY DEBRIS EFFECTS ON BIOGEOCHEMISTRY IN TWO RECONSTRUCTED SOILS IN THE ATHABASCA OIL SANDS REGION IN ALBERTA, CANADA
DownloadFall 2015
Forest floor mineral soil mix (FMM) and peat mineral soil mix (PMM) are cover soils commonly used for land reclamation post open pit oil sands mining in northern Alberta, Canada. While in such land reclamation practices the organic matter comes from the peat material salvaged before land...

Competition Impacts on Hybrid Poplar and Implications for Alternative Establishment Systems
DownloadSpring 2015
The effects of different vegetation control practices on tree-weed interactions and associated establishment and early tree growth were investigated in 1-3 year old hybrid poplar plantations containing Walker poplar (Populus deltoides x (P. laurifolia x P. nigra)) and its progeny Okanese poplar...

Fall 2015
The Canadian boreal forest is vital breeding habitat for North American songbirds. Extensive anthropogenic disturbances within this biome are therefore of conservation concern. Using unharvested stands as controls, I examined the effects of variable retention management (VRM) relative to...

Crown Architecture, Wood Stiffness and the Pipe Model Theory for White Spruce [Picea glauca (Moench) Voss] and Aspen (Populus tremuloides Michx.)
DownloadFall 2015
In forestry, the wood fibre supply chain describes the integration of harvesting operations, raw material transformation and end-product marketing. The forest industry may achieve an overall greater return on investment by developing a supply chain which incorporates measures of wood quality. The...
