Controls on carbon and energy exchange by a black spruce–moss ecosystem: Testing the mathematical model Ecosys with data from the BOREAS Experiment
Download2001
Massheder, J.M., Berry, J.A., Scott, S.L., Rayment, M., Jarvis, P.G., Grant, R.F., Hale, S.E., Moncrieff, J.B.
Stomatal limitations to mass and energy exchange over boreal black spruce forests may be caused by low needle N concentrations that limit CO(2) fixation rates. These low concentrations may be caused by low N uptake rates from cold boreal soils with high soil C:N ratios and by low N deposition...

The impact of phloem nutrients on overwintering mountain pine beetles and their fungal symbionts
Download2012
Erbilgin, N., Goodsman, D. W., Lieffers, V. J.
In the low nutrient environment of conifer bark, subcortical beetles often carry symbiotic fungi that concentrate nutrients in host tissues. Although bark beetles are known to benefit from these symbioses, whether this is because they survive better in nutrient-rich phloem is unknown. After...

Functional characterization of the L-type Amino acid Transporters (LATs) in Arabidopsis thaliana
DownloadFall 2012
The distribution of amino acids (AAs) in plants is a complex process that involves 67 amino acid transporters (AATs) in Arabidopsis, many of which have yet to be characterized. The L-type Amino acid Transporter (LAT) family, which in Arabidopsis contains five members, remained uncharacterized in...

Analysis of Nitrogen Species in Gas Oils Using High Performance Liquid Chromatography and Fourier Transform Ion Cyclotron Resonance Mass Spectrometry
DownloadFall 2012
The nitrogen content of products derived from oil sands bitumen is important, as nitrogen causes problems in upgrading and hydrotreating. Normal phase high performance liquid chromatography (HPLC) has been previously used to attempt separation of the nitrogen group types (pyrrole and pyridine)...

Nitrous Oxide Emission Reduction in an Annual Cropping System as a function of Nitrification Inhibitors and Liquid Manure Injection Timings
DownloadFall 2016
Nitrous oxide (N2O) contributes to global warming and ozone depletion. Two-thirds of the global N2O emissions are derived from agricultural soils receiving manure or fertilizer applications. The goal of this study was to identify and develop management practices that can decrease N2O emissions...

Spring 2013
Titanosilicate has unique properties in adsorptive separations such as air separations. In this study, Ag-ETS-10 was investigated for argon free oxygen production. During laboratory scale breakthrough experiments high purity (99.7+%) oxygen was produced at 100 kPa and 25 °C, with a recovery rate...

Fall 2017
Anthropogenic carbon dioxide emissions are driving climate change. The largest sources of emitted carbon dioxide are coal and fossil fuel power plants. One proposed solution to mitigate emissions is to capture carbon dioxide from fossil fuel power plants and store it underground. This is the...

Phytoremediation of Nitrogen Impacted Soil and Groundwater at a Fertilizer Facility in Central Alberta
DownloadFall 2012
In-situ remediation techniques such as phytoremediation have shown promise as economical alternatives for reducing the risk of environmental contaminants at impacted sites. Research trials were initiated to determine the efficacy of phytoremediation for soil and groundwater contaminated with high...

Methane Production and Emission Mitigation in Oil Sands Tailings Concurrent with Hydrocarbon Degradation under Nitrogen Limited Conditions
DownloadFall 2020
Alberta’s oil sands generate large volumes of tailings from bitumen ore processing. These tailings ponds produce biogenic methane, which can be measured across 60-80% of the tailings surface. Based on current surface area data and emissions studies, tailings ponds could account for 8% of Canada’s...
