Methane Producing and Oxidizing Microorganisms Display a High Resilience to Drought in a Swedish Hemi-Boreal Mire
Resource
An increased frequency of droughts due to anthropogenic climate change can lead to considerable stress for soil microorganisms and their functioning within northern peatlands. A better understanding...

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...
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...
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...
Responses to Projected Changes in Climate and UV-B at the Species Level
Resource
Environmental manipulation experiments showed that species respond individualistically to each environmental-change variable. The greatest responses of plants were generally to nutrient, particularly...
Responses to Projected Changes in Climate and UV-B at the Species Level
Project
Organization:
This project is part of an holistic approach to assess impacts of climate change on Arctic terrestrial ecosystems. It focuses on current, short-term phenotypic, and longer-term genetic responses of...
Selection for Forage and Avoidance of Risk by Woodland Caribou (Rangifer tarandus caribou) at Coarse and Local Scales
Resource
The relationship between selection at coarse and fine spatiotemporal spatial scales is still poorly understood. Some authors claim that, to accommodate different needs at different scales, individuals...
Semi-aquatic Mammals: Annotated Bibliography
Resource
Annotated bibliography contains 776 entries grouped under the species: muskrat, beaver, mink, and otter
Space-use Behaviour of Woodland Caribou Based on a Cognitive Movement Model
Resource
Movement patterns offer a rich source of information on animal behaviour and the ecological significance of landscape attributes. This is especially useful for species occupying remote landscapes...
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...
The Decreasing Availability of Reindeer Forage in Boreal Forests During Snow Cover Periods: A Sámi Pastoral Landscape Perspective in Sweden
Resource
This paper argues that Sámi reindeer pastoralism in Sweden is highly stressed during the critical snow cover periods due to large-scale human interventions, especially forestry, and that these have...

Video - Capture Sand in Flocculated Fines: A New Approach to optimize the Capture of Oil Sands Fines in Sand Beach
Resource
Ruijun Sun is a Senior Research Engineer with the Saskatchewan Research Council (SRC), Saskatoon, Saskatchewan. Ruijun Sun describes a new way to optimize the capture of oil sands clay fines in sand...
Video - Cleaning Up Mines in Northern Saskatchewan
Resource
Uranium mining in the Athabasca Basin region in Northern Saskatchewan was developed in the early 1950s. The mines developed during this period were abandoned, leaving deep holes and mining debris...
Video - Cleaning up the Lorado Uranium Mill
Resource
In 1960, the Lorado Mill was abandoned in northern Saskatchewan, leaving an estimated 227,000 cubic meters of radioactive uranium tailings that covered the mill site and flowed into nearby Nero Lake...
Video - Column Consolidation Testing of Oil Sands Tailings
Resource
Ruijun Sun is a Senior Research Engineer with the Saskatchewan Research Council, Saskatoon, Saskatchewan. He reports on consolidation testing of oil sands tailings from Total's Joslyn oil sands mine...
