Biodiversity of soil arthropods in a native grassland in Alberta, Canada: obscure associations and effects of simulated climate changeDownload
Soils have traditionally been treated as a “black box” due to the challenges of studying this complex medium. The living component of soil consists of a complex network of roots and mostly very small, highly abundant, and extremely diverse group of microbes, protists, and other invertebrates. In...
Boreal forest CO2 exchange and evapotranspiration predicted by nine ecosystem process models: Inter-model comparisons and relationships to field measurementsDownload
Nine ecosystem process models were used to predict CO2 and water vapor exchanges by a 150-year-old black spruce forest in central Canada during 1994-1996 to evaluate and improve the models. Three models had hourly time steps, five had daily time steps, and one had monthly time steps. Model input...
A study was initiated in 1988 to evaluate the effects of pipeline construction on soil compaction in the province of Alberta. The pipelines were located throughout Alberta on a number of different soils and were constructed using various techniques. Cone penetration resistance of soils (soil...
This study was initiated in 1988 to evaluate the effects of pipeline construction on soil strengths of various soils in the province of Alberta. The pipelines were scattered throughout Alberta on a number of different soils and were constructed using various techniques. At each of the fifteen...
Effects of long-term nitrogen and sulfur deposition on soil microbial communities and soil properties in the Athabasca oil sands region in northern Alberta, CanadaDownload
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...
This literate review evaluates the information available on the effects of overstripping topsoil during pipeline construction on native rangelands in southeastern Alberta. The effects on soil quality and handling of Chernozemic and Solonetzic soils are presented in detail as these are the...
Influence of Soil Cap Depth and Vegetation on Reclamation of Phosphogypsum Stacks in Fort Saskatchewan, AlbertaDownload
This study quantified environmental parameters to develop reclamation strategies for phosphogypsum stacks. Research was conducted on phosphogypsum stack experimental plots established in 2006 (6 soil cap depths, 5 vegetation treatments), and soil capped slopes seeded in 1998. Significant root...
Detailed GIS studies across spatially complex rangeland landscapes, including the Aspen Parkland of western Canada, require accurate digital elevation models (DEM). Following the interpolation of last return lidar (light detection and ranging) data into a DEM, a series of 256 reference plots,...
Confidence in regional estimates of N2O emissions used in national greenhouse gas inventories could be improved by using mathematical models of the biological and physical processes by which these emissions are known to be controlled. However these models must first be rigorously tested against...
