Controls on Methylmercury Concentrations in Lakes and Streams of Peatland-Rich Catchments Along a 1700 km Permafrost Gradient
Resource
Permafrost thaw may increase the production of neurotoxic methylmercury (MeHg) in northern peatlands, but the downstream delivery of MeHg is uncertain. We quantified total mercury (THg) and MeHg...
Erasing Anthropogenic Disturbance: Natural Revegetation of Linear Features Following Wildfire, and the Implications for Woodland Caribou (Rangifer tarandus caribou) Habitat Management
Resource
The federal recovery strategy for woodland caribou identifies wildfires within the last 40 years and anthropogenic disturbance visible at a scale of 1:50,000, including a 500-m buffer, as disturbed...
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...
Large Stocks of Peatland Carbon and Nitrogen are Vulnerable to Permafrost Thaw
Resource
Northern peatlands have accumulated large stocks of organic carbon (C) and nitrogen (N), but their spatial distribution and vulnerability to climate warming remain uncertain. Here, we used machine...
Mechanized Tree Planting in Sweden and Finland: Current State and Key Factors for Future Growth
Resource
In Fennoscandia, mechanized tree planting is time-efficient and produces high-quality regeneration. However, because of low cost-efficiency, the mechanization of Fennoscandian tree planting has been...
Microtopography Matters: Belowground CH4 Cycling Regulated by Differing Microbial Processes in Peatland Hummocks and Lawns
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...
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...
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 Boreal-Arctic Wetland and Lake Dataset
Resource
Here we present the Boreal–Arctic Wetland and Lake Dataset (BAWLD), a land cover dataset based on an expert assessment, extrapolated using random forest modelling from available spatial datasets of...
Using LiDAR, Colour Infrared Imagery, and Ground Truth Data for Mapping and Characterizing Vegetation Succession on Disturbance Types: Implications for Woodland Caribou (Rangifer tarandus caribou) Habitat Management
Resource
Woodland caribou (Rangifer tarandus caribou) occur throughout Canada’s boreal forest and have been declining both in distribution and population size along the southern extent of their range...
Vegetation Recovery on Low Impact Seismic Lines in Alberta's Oil Sands and Visual Obstruction of Wolves (Canis lupus) and Woodland Caribou (Rangifer tarandus caribou)
Resource
Low-Impact Seismic (LIS) exploration techniques are being increasingly used in northeastern Alberta, Canada to explore for in-situ oil sands deposits. These narrow (2-4-m wide), meandering man-made...
Video - Using Pellet-group Counts to Illustrate Changes in Reindeer Habitat Use in a Managed Boreal Forest
Resource
At the 14th North American Caribou Workshop, held in September 2012, Anna Skarin presented research conducted in northern Sweden on the effects of new infrastructure on semi-domesticated reindeer in the area.
Warming Response of Peatland CO2 Sink is Sensitive to Seasonality in Warming Trends
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...
Wellsite Selection by Grizzly Bears Ursus arctos in West-central Alberta
Resource
Oil and gas development is widespread in west – central Alberta, yet little is known about the potential impacts of oil and gas activities on grizzly bear habitat use. Focusing on the impacts of one...
