Methane Cycling in Horticultural Extracted, Restored, and Unrestored Peatlands in Central Alberta
Resource
Horticulture peat extraction drastically changes peatland ecosystems and their carbon and greenhouse gas balance. Comprehensive study on the combined response of methane (CH4) cycling (i.e., CH4...
Methane Cycling Microbial Community Characteristics: Comparing Natural, Actively Extracted, Restored and Unrestored Boreal Peatlands
Resource
The microbial community in peat is responsible for organic matter degradation and greenhouse gas emissions, yet its response to peat extraction and peatland restoration remains poorly understood. We...

Nested Population Structure of Threatened Boreal Caribou Revealed by Network Analysis
Resource
Delineating relevant local populations of widely distributed species is a common challenge in conservation ecology. Caribou and reindeer ( Rangifer tarandus) are in general decline throughout their...
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...
Polychlorinated Dibenzodioxins, Dibenzofurans and Non-ortho Substituted Polychlorinated Biphenyls in Caribou (Rangifer tarandus) from the Canadian Arctic
Resource
The presence of contaminants in the Arctic environment has raised concerns regarding levels in wildlife and possible effects on the health of wildlife populations. In addition, contaminants in wild...
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...
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...
Re-establishment of Peatland Vegetation Following Surface Leveling of Decommissioned In Situ Oil Mining Infrastructures

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.
