Low-impact Line Construction Retains and Speeds Recovery of Trees on Seismic Lines in Forested Peatlands
Resource
Seismic lines, linear features originating from the oil and gas industry for energy exploration, pose a substantial management challenge due to their collective impact on biogeochemical cycles, plant...
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
Recent Climate Change has Driven Divergent Hydrological Shifts in High-latitude Peatlands
Resource
High-latitude peatlands are changing rapidly in response to climate change, including permafrost thaw. Here, we reconstruct hydrological conditions since the seventeenth century using testate amoeba...
Soluble Calcium and Sulphate Excesses Related to Stress in Pinus contorta on Peat Amendments of Reclaimed Landscapes in the Boreal Oil Sands Region
Resource
Results indicated a negative relationship among pine performance with increasing soluble calcium and available sulphate-S
Spatial and Temporal Changes in Seasonal Range Attributes in a Declining Barren-ground Caribou Herd
Resource
From 1996 to 2015 the Bathurst caribou herd has declined from approximately 349,000 to 20,000 animals. Aboriginal traditional knowledge (TK) has recently observed the later arrival of the herd below...
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...
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...
Tools for Arctic Revegetation: What's in Your Toolbox?
Resource
Revegetation in arctic climates is a challenge for many reasons. There are two approaches to arctic revegetation: natural regeneration and active reclamation. Natural regeneration is an inexpensive...
Unexpected Greening in a Boreal Permafrost Peatland Undergoing Forest Loss is Partially Attributable to Tree Species Turnover
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...
Video - Wolves, Deer and Beaver: Implications of Prey Enrichment and Seasonal Prey Switching for Woodland Caribou Declines
Resource
At the 14th North American Caribou Workshop held in September 2012, Kyle Knopff presented research done researchers from the University of Alberta, University of Montana and Golder Associates Ltd.
Water for the Futures We Want - Opportunities for Research, Practice, and Leadership in Achieving SDG 6
Resource
Canada and the world are faced with unprecedented water-related challenges which impact our ability to meet many of the UN sustainable development goals. Climate warming and human actions are altering...
Webinar - Caribou Habitat Restoration: A Trial in Northeastern Alberta
Resource
Woodland caribou (Rangifer tarandus caribou) are a threatened species federally and provincially in Alberta. Habitat restoration is critical to maintaining suitable habitat to support healthy...
