How Linear Features Alter Predator Movement and the Functional Response
Resource
In areas of oil and gas exploration, seismic lines have been reported to alter the movement patterns of wolves (Canis lupus). We developed a mechanistic first passage time model, based on an...
Hydrological Functioning of a Constructed Peatland Watershed in the Athabasca Oil Sands Region: Potential Trajectories and Lessons Learned
Resource
This resource is available on an external database and may require a paid subscription to access it. It is included on the CCLM to support our goal of capturing and sharing the breadth of all...
Hydrological Functions of a Peatland in a Boreal Plains Ecosystem

Increasing Contributions of Peatlands to Boreal Evapotranspiration in a Warming Climate
Resource
The response of evapotranspiration (ET) to warming is of critical importance to the water and carbon cycle of the boreal biome, a mosaic of land cover types dominated by forests and peatlands. The...
Insect-mediated Apparent Competition Between Mammals in a Boreal Food Web
Resource
While the important role of animal-mediated interactions in the top-down restructuring of plant communities is well documented, less is known of their ensuing repercussions at higher trophic levels...
Inuit Knowledge of Long-term Changes in a Population of Arctic Tundra Caribou
Resource
Indigenous peoples possess knowledge about wildlife that dates back many generations. Inuit observations of historical changes in a caribou population on southern Baffin Island, collected from 43...
Investigation of Microbial Community Response During Oil Sands Reclamation via Lipid and Carbon Isotope Analyses
Resource
In this study, phospholipid fatty acids (PLFA) and carbon isotopes were used to characterize the response of in situ microbial communities to a pilot-scale wetland reclamation project in the Alberta...

Large Scale Mapping of Soil Organic Carbon Concentration with 3D Machine Learning and Satellite Observations
Resource
Canada has extensive forests and peatlands that play key roles in global carbon cycle. Canadian soils and peatlands are assumed to store approximately 20% of the world’s soil carbon stock. However...
Lichens: A Limit to Peat Growth?
Resource
The fruticose lichens Cladina stellaris and Cladina rangiferina, form thick mats that can cover large areas of northern peatlands (above c. 50° latitude), including the extensive peatlands of the...
Long Term Population Fluctuations and Winter Foraging Ecology of Arctic Tundra Caribou
Project
Organization:
This PhD project used Inuit knowledge and aerial survey data across many years to analyse distribution, forage selection, foraging ecology, and physical condition of caribou in the arctic.
Long Term Population Fluctuations and Winter Foraging Ecology of Arctic Tundra Caribou
Resource
Caribou ( Rangifer tarandus) are affected by density-dependent and -independent processes at various temporal scales. Populations residing on Arctic tundra can be affected by both density-independent...
Mapping Smouldering Fire Potential in Boreal Peatlands and Assessing Interactions with the Wildland-Human Interface in Alberta, Canada

Modelling Transverse Mixing of Sediment and Vanadium in a River Impacted by Oil Sands Mining Operations
Resource
A novel, quasi-two-dimensional surface water-quality modelling approach is presented in which the model domain can be discretised in two dimensions, but a one-dimension solver can still be applied to...
Motorized Activity on Legacy Seismic Lines: A Predictive Modeling Approach to Prioritize Restoration Efforts
Resource
Natural regeneration of seismic lines, cleared for hydrocarbon exploration, is slow and often hindered by vegetation damage, soil compaction, and motorized human activity. There is an extensive...
Multi-year Assessment of Water and Energy Exchange From an Oil Sands Reclamation Cover, Fort McMurray, Canada
Resource
In most years, evaporation exceeds summer rainfall. Using natural aspen stands as a comparison, it is expected that water use from the soil cover will continue to increase as the ecosystem ages.
