Ecological Response of Atmospheric Nitrogen Deposition on Reconstructed Soils in the Athabasca Oil Sands Region
DownloadSpring 2012
Oil and gas extraction in the Athabasca oil sands region has increased anthropogenic nitrogen (N) emissions over the past two decades. This study quantified atmospheric N deposition and assessed the potential implications of increased N deposition in aspen (Populus tremuloides Michx.) and jack...

Fall 2015
Assessment of microbial community development is required to determine the success of reclamation process on disturbed land after mining. Peat (PMM) or LFH mineral soil mix (LFH) is used as capping material in reclamation. Application of coarse woody debris (CWD) also facilitates reclamation by...

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...
