Effects of long-term nitrogen and sulfur deposition on soil microbial communities and soil properties in the Athabasca oil sands region in northern Alberta, Canada
DownloadFall 2016
Intensified oil sands activities have resulted in elevated levels of nitrogen (N) and sulfur (S) deposition in the mixedwood boreal forest in the Athabasca oil sands region (AOSR) of northern Alberta, Canada. The deposition of N and S can affect the surrounding ecosystem and it is important to...

Influence of Amendments and Soil Depth on Available Nutrients and Microbial Dynamics in Contrasting Topsoil Materials Used for Oil Sands Reclamation
DownloadFall 2015
As of December 2013, the cumulative area disturbed by oil sands mining in NE Alberta was 896 km2 out of an estimated final footprint of 4,800 km2 – all of which will require reclamation. Expensive handling costs and scarce soil resources necessitate judicious management and application of...

Southeast Asian dipterocarp forests are highly diverse tropical forest communities, with the family Dipterocarpaceae alone comprising hundreds of species. Dipterocarps are remarkable in that they exhibit supra-annual mass flowering events, which occur in irregular intervals of two to ten years,...

Influence of variable retention and deadwood characteristics on saproxylic beetles in boreal white spruce stands
DownloadSpring 2016
Retention forestry aims to maintain a significant level of continuity in forest structure, composition and complexity so as to support conservation and recovery of biodiversity and ecological function on managed landscapes; however, the amount and distribution of retention that best meets...

Nitrogen, plant and microbial community dynamics in sites recovering from wildfire and surface mining in the Athabasca Oil Sands Region
DownloadSpring 2016
For reclamation to be considered successful, an ecosystem must be self-sustaining and have a recovery trajectory that falls within the range of variability of ecosystem function in natural ecosystems. This study compared the soil nitrogen availability, soil microbial community, and understory...

Natural regeneration in the boreal forest: seedling establishment and success in western North American and European boreal forests
DownloadFall 2014
As the costs and ecological implications of intensive forest management rise, alternative management strategies that minimize intervention become more desirable options, particularly natural regeneration. Two locations were studied: the boreal mixedwoods of western North America (Alberta) and...
