Characterization of Soil Spatial Heterogeneity and Improvement of Capping Materials for Oil Sands Mine Reclamation
DownloadFall 2018
Surface mining in the Athabasca Oil Sands Region (AOSR), Alberta, Canada creates a large-scale ecosystem disturbance requiring ‘land reclamation’. Mining approvals require that land reclamation returns the sites to an equivalent land capability class, but this goal has proven challenging to...

Seeing the forest for the soil: topographic controls on soil carbon dynamics in the boreal mixedwood forest
DownloadFall 2018
Boreal forest soils store an estimated 272 Pg of carbon. Due to a high degree of spatial heterogeneity, there is a wide range in carbon stores in this ecosystem. Changes in topography and forest structure are important to carbon distribution, influencing the soil microclimate and the chemical...

Soil CO2 Efflux in Response to Forest Disturbances and its Spatial Variation in a Boreal Mixedwood Forest
DownloadSpring 2019
Soil CO2 efflux is a key component of the terrestrial carbon cycle as it is the second largest carbon flux between the atmosphere and terrestrial ecosystems after photosynthesis. The spatial and temporal variation of soil CO2 efflux can be altered by various disturbancess, which in turn alter...
