Disturbance Effects of Oil Sands Exploration Practices on Coarse-textured Soils and Populus tremuloides Michx. Regeneration
DownloadSpring 2018
Oils sands exploration (OSE) sites associated with in situ oil sands development are required to evaluate and delineate oil resources. Once these sites are cleared and disturbed for exploration, they can result in habitat disturbance and fragmentation, invasion of weed species, changes to surface...

Diverting Resources to Turn on Resistance: Influences of Biotic and Abiotic Stresses on Aspen Seedlings
DownloadFall 2012
The interactions between biotic and abiotic stresses and their influence on plant reserves in non-photosynthetic tissues (i.e., roots and stems) and the role of plant reserves in tree defenses are poorly understood. Aspen seedlings grown under different conditions (light, fertilizer) were grouped...

Role of host identity, stand composition, soil type and disturbance severity in structuring ectomycorrhizal communities in the boreal forest
DownloadSpring 2018
The symbiosis between trees and ectomycorrhizal fungi (EMF) is essential for tree establishment and survival in the boreal forest because it is a disturbance prone ecosystem characterized by long harsh winters and low nutrient mobility. Ectomycorrhizal fungal community composition can be...

The Role of Nutrient and Carbon Reserve Status of Aspen Seedlings in Root-Soil Interactions
DownloadFall 2015
The boreal forest is one of the largest forest ecosystems in the world, covering 14.7 million km2 globally. The Canadian boreal forest has a wealth of natural resources, including coal, timber, and oil; as resource exploration and exploitation has expanded, anthropogenic disturbance in the boreal...

The seasonality of non-structural carbohydrates in mature boreal Betula papyrifera and potential constraints in their remobilization
DownloadSpring 2023
Assimilated non-structural carbohydrates (NSC) can be stored as reserves in plants and remobilized during periods of asynchrony between carbon acquisition and carbon demand to fuel essential metabolic functions and growth. However, the framework of NSC allocation to reserves and their...

Transfer of live aspen roots as a reclamation technique - Effects of soil depth, root diameter and fine root growth on root suckering ability
DownloadFall 2012
A transfer of live trembling aspen (Populus tremuloides Michx.) roots including the surrounding forest floor was conducted to examine aspen’s ability of vegetative regeneration to establish a boreal forest on a reclamation site. Forest floor was salvaged at two depths (15 cm and 40 cm) from a...

Fall 2024
Phosphogypsum (PG) is a by-product of phosphorus fertilizer production and is piled into large stacks that eventually require reclamation. The first step in the reclamation process is constructing a topsoil cap to facilitate revegetation. An alternative to traditional topsoil caps underlain with...
