Fall 2024
Drought has an adverse effect on ecosystems, communities, and economies globally, making itdifficult to manage water resources. It is vital to comprehend the dynamics of drought and surfacewater extent in Alberta, Canada, where water resources are essential for maintaining ecosystemfunctions and...

Fire and harvesting impacts on forest floor and water extractable organic matter chemical composition in the Canadian Rocky Mountains
DownloadFall 2024
Forests globally store a significant portion of terrestrial organic carbon, where two-thirds of that carbon is stored as soil organic matter (SOM). The dissolved organic matter (DOM) in soils plays a crucial role in carbon and nutrient cycling. Understanding the dynamics of DOM and SOM in forest...

Landscape influences on downstream concentrations of mercury, methylmercury, and dissolved organic carbon in permafrost peatland catchments
DownloadFall 2024
Thawing permafrost in northern regions threatens to increase the downstream delivery of mercury (Hg) and its organic form, methylmercury (MeHg). Permafrost thaw may mobilize large Hg and dissolved organic carbon (DOC) stores from permafrost soils. Once mobilized, inorganic Hg (Hg(II)) can be...

Development of a Comprehensive Nitrogen Budget to Increase Nitrogen Use Efficiency and Reduce Nitrogen Losses in Semi-Arid Southern Alberta
DownloadSpring 2024
Synthetic nitrogen (N) fertilizer has increased crop yields, but crop nitrogen use efficiency (NUE) is low. The N fertilizer not taken up by the crop is subject to nitrate leaching, ammonia volatilization, and denitrification losses, contributing to declining air and water quality, ozone layer...

Growth and physiology of mycorrhizal plants in soil containing enhanced non-segregating oil sands tailings
DownloadFall 2024
Open-pit mining of oil sands in Alberta, Canada, has resulted in a large-scale land disturbance of the boreal forest ecosystem and produced large amounts of tailings. To improve the effectiveness of the tailings solidification process and to make the tailings less harmful to vegetation, the novel...

The role of forage quantity and quality in the migration and diet of a northern ungulate during their neonatal period
DownloadFall 2024
Migration has evolved as a strategy to maximize survival and reproductive success, driven by the search for better resources and predator avoidance. For ungulates at high latitudes, the search for higher quality and more abundant forage has been proposed as one of the best explanations of...

Biochar Addition Affects the Performance of Portland Cement Composites: Meta-analysis and Laboratory Experiments
DownloadFall 2024
Portland cement is the most widely used binder in construction. However, the production of Portland cement emits a large amount of CO2, and one strategy to decrease such anthropogenic CO2 emissions is to reduce the amount of Portland cement produced by partially replacing it with supplementary...

Perennial Forage Polycultures and Organic Amendments Drive Soil Carbon Sequestration and Organic Matter Stabilization: Results After 90 Years of Management at the Breton Plots
DownloadFall 2024
Increasing agricultural intensification threatens to strain already degrading global soil resources while simultaneously escalating anthropogenic greenhouse gas emissions. Loss of soil organic matter (SOM) from agroecosystems is a major cause of soil degradation and a source of considerable...

Fall 2024
Soil invertebrate assemblages, indicative of ecosystem health and function, can be used to assess land reclamation success, but require taxonomic expertise. Soil invertebrate assessments must be comprehensive, seasonally consistent, cost effective, and focus on sensitive key groups. We evaluated...

Perennial Forage Mixtures: An Integrated Approach to Investigating their Performance for Multifunctionality
DownloadFall 2024
Perennial forage mixtures are used in the feeding regimes of beef cattle producers in Alberta. This provides consistency in the supply of forage biomass and nutritive value to cover up lapses in annual forage supply, and adequately improve the performance of beef cattle. Additionally, perennial...
