The area burned by forest fires in Canada has increased over the past four decades, at the same time as summer season temperatures have warmed. Here we use output from a coupled climate model to demonstrate that human emissions of greenhouse gases and sulfate aerosol have made a detectable...

Models that describe the spread of invading organisms often assume that the dispersal distances of propagules are normally distributed. In contrast, measured dispersal curves are typically leptokurtic, not normal. In this paper, we consider a class of models, integrodifference equations, that...

Peat mineral soil mix has been the predominant cover soil used in Athabasca oil sands reclamation. Use of LFH mineral soil mix (forest litter layers and underlying mineral soil) has recently been mandated by regulatory approvals. Effectiveness of these cover soil types to provide diverse, native...

Re-establishment of appropriate vegetation communities is an important aspect of successful forest reclamation as they contribute to various ecosystem functions. In my research I explore how different coversoil materials (salvaged forest floor (FFM) and peat material), their placement depths, and...

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...

Effects of Root Zone pH, Calcium and Phosphorus Supply on Selected Boreal Forest Plant Species
DownloadSpring 2015
Soil pH is among the major environmental factors affecting plant growth. In the reclaimed areas following open-pit oil sands mining in northeastern Alberta, Canada, the pH of reclaimed soil is commonly higher than 8.0. The optimum range of soil pH for growth and the tolerance of pH extremes...
