A Strong Mitigation Scenario Maintains Climate Neutrality of Northern Peatlands
Resource
Northern peatlands store 300–600 Pg C, of which approximately half are underlain by permafrost. Climate warming and, in some regions, soil drying from enhanced evaporation are progressively...
Biogeochemical Response to Vegetation and Hydrologic Change in an Alaskan Boreal Fen Ecosystem
Resource
Boreal peatlands store approximately one third of the earth’s terrestrial carbon, locked away in currently waterlogged and frozen conditions. Peatlands of boreal and arctic ecosystems are affected...
Developing a Reclamation Costing Framework for the Athabasca Oil Sands
Resource
The Athabasca oil sands are a significant component of the economy in Alberta. However, they also represent a large environmental risk. At the end of mining operations, companies are expected to begin...
Environmental and Management Drivers of Carbon Dioxide and Methane Emissions From Actively-Extracted Peatlands in Alberta, Canada
Resource
The installation of drainage ditches and removal of vegetation in preparation for vacuum harvesting alters the carbon dynamics of peatlands. However, we lack the measurements to understand the spatial...
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...
Inuit Qaujimajatuqangit about Population Changes and Ecology of Peary Caribou and Muskoxen on the High Arctic Islands of Nunavut
Resource
Abstract Over the past 40 years, severe population fluctuations in Peary caribou ( Rangifer tarandus pearyi) and muskoxen ( Ovibos moschatus) living in the High Arctic of Nunavut has caused widespread...
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...
Peat Loss Collocates with a Threshold in Plant–Mycorrhizal Associations in Drained Peatlands Encroached by Trees
Resource
Drainage-induced encroachment by trees may have major effects on the carbon balance of northern peatlands, and responses of microbial communities are likely to play a central mechanistic role. We...
Remediation of Hydrocarbon Contaminated Soils in the Canadian Arctic by Landfarming
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...
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...
Swamplands: Tundra Beavers, Quaking Bogs, and the Improbable World of Peat
Resource
In a world filled with breathtaking beauty, we have often overlooked the elusive charm and magic of certain landscapes. A cloudy river flows into a verdant Arctic wetland where sandhill cranes and...
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...
The Impacts of Climate and Social Changes on Cloudberry (Bakeapple) Picking: A Case Study from Southeastern Labrador
Resource
Abstract The traditional subsistence activities of Indigenous communities in Canada's subarctic are being affected by the impacts of climate change, compounding the effects of social, economic and...
The Third Generation of Pan-Canadian Wetland Map at 10 m Resolution Using Multisource Earth Observation Data on Cloud Computing Platform
Resource
Development of the Canadian Wetland Inventory Map (CWIM) has thus far proceeded over two generations, reporting the extent and location of bog, fen, swamp, marsh, and water wetlands across the country...
