Kabin, Konstantin, Rankin, Robert, Sydorenko, Dmytro
A two-dimensional nonlinear multi-fluid MHD model of the ionosperic Alfven resonator is presented. The resonator is excited by a packet of shear Alfven waves propagating downward toward the ionosphere from high altitudes. It is shown that the nonlinear (ponderomotive) force of standing...

Transcriptome and Proteome Based Survey to Identify Aluminum-Responsive Genes in Roots of Arabidopsis Thaliana
DownloadSpring 2010
Aluminum (Al)stress is a major limitation to crop productivity on acidic soils. To help understand the cellular mechanisms underlying the toxicity and resistance of plants to Al, this thesis involved a large-scale, transcriptomic and proteomic analysis of roots of Arabidopsis thaliana and reports...

We examined whether the intense root competition in a rough fescue grassland plant community in central Alberta, Canada, was important in structuring plant species diversity or community composition. We measured competition intensity across gradients of species richness, evenness, and community...

Formation and Morphology of an Iron Plaque on the Roots of Typha latifolia L. Grown in Solution Culture.
Download1984
Taylor, G.J., Rodden, R., Crowder, A.A.
Roots of Typha latifolia L. exposed to Fe2+ under reduced conditions in solution culture developed visible coatings (plaques) of an oxidized Fe compound that extended as much as 15-17 ,um into the rhizosphere. Iron concentrations were significantly less and discoloration was not apparent on the...

Competition in Arabidopsis thaliana (L.) Heynh., behaviour of Mimosa pudica L. and a new method to characterize roots demonstrated with Helianthus annuus L..
DownloadFall 2016
In this dissertation, I address 5 problems in the discipline of plant ecology: two problems in plant competition, two problems in plant behaviour and one problem in the phenotyping of plant roots. First, we directly test Darwin’s competition-relatedness hypothesis with a pairwise...

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...

Roots in reconstructed soils - how land reclamation practices affect the development of tree root systems
DownloadSpring 2018
Tree root systems are incredibly complex organs that fulfill several vital functions, the main ones being anchorage and uptake of water and mineral elements. They perform these functions in a highly complex and challenging soil environment with heterogeneously distributed soil resources, physical...
