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...
Partitioning Forest-Floor Respiration into Source Based Emissions in a Boreal Forested Bog: Response to Experimental Drought
Resource
Northern peatlands store globally significant amounts of soil carbon that could be released to the atmosphere under drier conditions induced by climate change. We measured forest floor respiration (R...
Permafrost Thaw Causes Large Carbon Loss in Boreal Peatlands While Changes to Peat Quality are Limited
Resource
Rapid, ongoing permafrost thaw of peatlands in the discontinuous permafrost zone is exposing a globally significant store of soil carbon (C) to microbial processes. Mineralization and release of this...
Petroleum Exploration Increases Methane Emissions from Northern Peatlands
Resource
Peatlands are globally significant sources of atmospheric methane (CH4). In the northern hemisphere, extensive geologic exploration activities have occurred to map petroleum deposits. In peatlands...
Plow-in Pipeline Construction Improves Recovery of Rough Fescue Grassland
Resource
Plow-in pipeline approach resulted in a fescue-bluegrass vegetation community that had the best rough fescue recovery and greatest similarity to undisturbed natural grassland
Preferential Recharge in a Reclaimed Tailings Sand Upland: Implications on Solute Flushing
Resource
Given the potential for moisture limited conditions due to the sub-humid regional climate, ensuring sufficient water availability in these landscapes is a principal concern. This research demonstrates...
Prioritization can Improve Cost Effectiveness of Seismic Line Restoration
Resource
Upland mesic sites showed a relatively strong ability to regenerate on their own (passive restoration), while lowland (bogs and fens) and upland dry sites were slow to recover.
Protecting Forest Floor in Place Rather than Stripping it Off is a Better Strategy to Regenerated Temporary Drilling Pads
Resource
Where forest floor was protected from disturbance, there were approximately 10 times as many aspen sprouts that were at least 3 times as tall as sprouts in the area where floor was stripped & replaced
Provisioning Time and Central-place Foraging in Beavers
Resource
This study tested the effect of provisioning time by providing beavers in experimental enclosures with equal frequencies of saplings at various distances from the lodge and we compared the patterns of...
Rat Root Plants May Not be Suitable for Reclaiming Oil Sands Tailing Ponds
Resource
This study tested the ability of rat root to grow in a high pH/high salinity environment, similar to that of a constructed oil sands tailings pond wetland.
Reconstructed Soils in Alberta Oil Sands Limit Fine Root Growth of Trees
Resource
Tailings sand sites: fine root biomass decreased with depth and proximity to the textural interface. Overburden sites: fine root biomass decreased abruptly at the textural interface and EC increased
Re-establishment of Peatland Vegetation Following Surface Leveling of Decommissioned In Situ Oil Mining Infrastructures
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...
Replacing Natural Wetlands with Stormwater Management Facilities: Biophysical and Perceived Social Values
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...
Restoration Approach Influences Carbon Exchange at In-Situ Oil Sands Exploration Sites in East-Central Alberta
Resource
This article outlines the results of monitoring two restored oil sands exploration sites, and discusses the effectiveness of treatments on tree recovery and greenhouse gas emissions.
Restoration of Boreal Peatland Impacted by an In-situ Oil Sands Well-pad 1: Vegetation Response
Resource
The prompt introduction and establishment of peatland donor species through moss layer transfer technique was crucial to the overall re-establishment of peatland vegetation.
Rethinking Restoration Ecology of Tallgrass Prairie: Considering Belowground Components of Tallgrass Restoration in Southern Ontario
Resource
Agriculture, urban development, and woody encroachment have reduced the North American tallgrass prairie ecosystem to less than 1% of its historical extent. The remnants of this now rare habitat are...
