On the Use of Mulching to Mitigate Permafrost Thaw due to Linear Disturbances in Sub-Arctic Peatlands
Resource
The presence or absence of permafrost strongly influences the hydrology and ecology of northern watersheds. Resource exploration activities are currently having profound effects on hydrological and...
Paleolimnological Assessment of Past Hydro-ecological Variation at a Shallow Hardwater Lake in the Athabasca Oil Sands Region Before Potential Onset of Industrial Development
Resource
Effective environmental monitoring requires knowledge of inherent natural variation. In the absence of pre-development monitoring of aquatic ecosystems, paleolimnological approaches have been...
Predicting Patterns of Terrestrial Lichen Biomass Recovery Following Boreal Wildfires
Resource
New allometric equations to estimate lichen biomass from field measurements of lichen cover and height; allometries were consistent among ecoprovinces, suggesting generalizability
Resource Separation Analysis with Moose Indicates Threats to Caribou in Human Altered Landscapes
Resource
Species recovery is often impeded by inadequate knowledge on mechanisms of community interactions that cause and exacerbate species endangerment. Caribou and wild reindeer Rangifer tarandus are...
Satellite Determination of Peatland Water Table Temporal Dynamics by Localizing Representative Pixels of A SWIR-Based Moisture Index
Resource
The OPtical TRApezoid Model (OPTRAM) is a physically-based approach for remote soil moisture estimation. OPTRAM is based on the response of short-wave infrared (SWIR) reflectance to vegetation water...
Saving Endangered Species Using Adaptive Management
Resource
Adaptive management is a powerful means of learning about complex ecosystems, but is rarely used for recovering endangered species. Here, we demonstrate how it can benefit woodland caribou, which...
Scaling Up the Role of Predation in Caribou Declines in West-Central Alberta (Redwillow, Narraway, Redrock Prairie Creek, A la Pêche and Little Smoky Ranges)
Resource
Anthropogenic disturbances contribute to the way animals perceive and respond to their environment. These multiple disturbances can additionally act in non-independent ways to shape an animal’s...
Scaling Up the Role of Predation in Caribou Declines in West-Central Alberta (Redwillow, Narraway, Redrock Prairie Creek, A la Pêche and Little Smoky Ranges). 2012 AUPRF project status update
Resource
Avoidance by caribou and increased wolf predation risk in disturbed areas indicate functional habitat loss for caribou, yet these patterns alone do not necessarily imply a demographic impact. Spatial...
Scaling Up the Role of Predation in Caribou Declines in West‐Central Alberta (Redwillow, Narraway, Redrock Prairie Creek, A la Pêche and Little Smoky Ranges). Interim Report
Resource
Our primary goal is to address the relative contributions of forestry and oil and gas production to the decline of caribou populations. This knowledge can then be used to develop appropriate...
Selection of Both Habitat and Genes in Specialized and Endangered Caribou
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...
Spatial and Temporal Variation in Forest Transpiration Across a Forested Boreal Peatland Complex
Resource
Transpiration is a globally important component of evapotranspiration. Careful upscaling of transpiration from point measurements is thus crucial for quantifying water and energy fluxes. In spatially...
Species-Specific Responses to Wetland Mitigation among Amphibians in the Greater Yellowstone Ecosystem
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...
Species-Specific Responses to Wetland Mitigation among Amphibians in the Greater Yellowstone Ecosystem

Tactical Departures and Strategic Arrivals: Divergent Effects of Climate and Weather on Caribou Spring Migrations
Resource
A 2019 academic paper that looks at factors affecting caribou migration timing and speed. The paper concludes that later arrival at calving grounds might indicate that females are in worse condition...
Temperature, Moisture and Freeze–thaw Controls on CO2 Production in Soil Incubations From Northern Peatlands
Resource
Peat accumulation in high latitude wetlands represents a natural long-term carbon sink, resulting from the cumulative excess of growing season net ecosystem production over non-growing season (NGS)...
The Biophysical Climate Mitigation Potential of Boreal Peatlands During the Growing Season
Resource
Peatlands and forests cover large areas of the boreal biome and are critical for global climate regulation. They also regulate regional climate through heat and water vapour exchange with the...
The Hydrology of Interconnected Bog Complexes in Discontinuous Permafrost Terrains
Resource
In the zone of discontinuous permafrost, the cycling and storage of water within and between wetlands is poorly understood. The presence of intermittent permafrost bodies tends to impede and re-direct...
The Influence of Postfire Recovery and Environmental Conditions on Boreal Vegetation
Resource
Climate change is increasing the frequency and extent of fires in the boreal biome of North America. These changes can alter the recovery of both canopy and understory vegetation. There is uncertainty...
