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 Mesostigmata (Arachnida: Parasitiformes) in boreal forests of Alberta: diversity and utility as indicators of disturbance
DownloadSpring 2018
Soils provide numerous ecosystem services, including provision of nutrients for plants, sequestration of greenhouse gases, and serving as habitat for soil animals. Soil animal diversity is immense, and many undescribed taxa still remain. One prominent group that inhabits soils is mites...

Fall 2015
The recent open pit mining for oil sands in the Athabasca Oil Sands Region (AOSR), northern Alberta has created an unprecedented industrial scale disturbance whose ecological consequences is not well understood, and requires intensive investigation. This study focused on the temporal dynamics of...

The ecology of boreal forest floor microbial communities in relation to environmental factors
DownloadFall 2012
Soil microbial communities in boreal forests are structured by complex interactions among many factors operating simultaneously on large and small spatial scales. Of particular note in the boreal mixedwood, the microbial communities under trembling aspen and white spruce forest floors are...

The effects of subsoil ripping on soil physical properties and soil water dynamics on reconstructed soils at Genesee Prairie Mine, Alberta
DownloadSpring 2014
Surface mining activities have significantly depleted natural tree cover, especially trembling aspen (Populus tremuloides), in the Boreal Forest and Aspen Parkland Natural Regions of Alberta. The natural soil profile is usually destroyed during these mining activities and soil and landscape...

The role of terrestrial vegetation in atmospheric Hg deposition: Pools and fluxes of spike and ambient Hg from the METAALICUS experiment
Download2012
Graydon, J.A., Harris, R., St. Louis, V., Sandilands, K.A., Rudd, J.W.M., Kelly, C.A., Richardson, M., Emmerton, C.A., Lindberg, S.E., Tate, M.T., Asmath, H., Krabbenhoft, D.P.
As part of the Mercury Experiment to Assess Atmospheric Loading in Canada and the U.S. (METAALICUS), different stable Hg(II) isotope spikes were applied to the upland and wetland areas of a boreal catchment between 2001 and 2006 to examine retention of newly deposited Hg(II). In the present...

The Technical Efficiency of Wildfire Suppression in Alberta, Canada: A Stochastic Frontier Analysis
DownloadFall 2021
Wildfire management agencies are increasingly interested in the efficiency of wildfire suppression as they work to protect human lives and communities from wildfire damages under constrained management budgets. In Alberta, climate change is expected to increase the length of the wildfire season...

Triage for conserving populations of threatened species: The case of woodland caribou in Alberta.
Download2010
Hauer, G., Adarnowicz, W., Boutin, S., Schneider, R.
Prioritization of conservation efforts for threatened and endangered species has tended to focus on factors measuring the risk of extirpation rather than the probability of success and cost. Approaches such as triage are advisable when three main conditions are present: insufficient capacity...
