Balancing Between Predation Risk and Food by Boreal Breeding Ducks
Resource
Wetlands belong to the globally most threatened habitats, and organisms depending on them are of conservation concern. Wetland destruction and quality loss may affect negatively also boreal breeding...
Can Plant or Lichen Natural Abundance 15N Ratios Indicate the Influence of Oil Sands N Emissions on Bogs?
Resource
The 140,329 km 2 Athabasca Oil Sands Administrative Area (OSAA), which contains 8982 km 2 of bogs. Since the late 1970s, N emissions from oil sands development in the OSAA have steadily increased...
CEMA Resources Available Online
News
The Cumulative Environmental Management Association (CEMA) was a leading multi-stakeholder group operating in the heart of Canada’s boreal forest - the Regional Municipality of Wood Buffalo, Alberta...
Decreased Carbon Accumulation Feedback Driven by Climate‐Induced Drying of Two Southern Boreal Bogs over Recent Centuries
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...
Environmental Spaces for Palsas and Peat Plateaus are Disappearing at a Circumpolar Scale
Resource
The anthropogenic climate change threatens northern permafrost environments. This compromises the existence of permafrost landforms, such as palsas and peat plateaus, which have been assessed to be...
Historical Landscape Use of Migratory Caribou: New Insights From Old Antlers
Resource
Accumulations of shed caribou antlers ( Rangifer tarandus) are valuable resources for expanding the temporal scope with which we evaluate seasonal landscape use of herds. Female caribou shed their...
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...
Intra- and Interspecific Variation in Spectral Properties of Dominant Sphagnum Moss Species in Boreal Peatlands
Resource
Boreal peatlands store ~25 % of global soil organic carbon and host many endangered species; however, they face degradation due to climate change and anthropogenic drainage. In boreal peatlands...
Modeled Production, Oxidation, and Transport Processes of Wetland Methane Emissions in Temperate, Boreal, and Arctic Regions
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...
Monitoring Recovery of Overgrazed Lichen Communities on Hagemeister Island, Southwestern Alaska
Resource
Understanding the recovery rate of overgrazed lichen communities has value to mangers of lands in northern regions. We describe lichen community composition and present recovery rate measurements for...
Rapid Transformation of Tundra Ecosystems From Ice-wedge Degradation

Recent Climate Change has Driven Divergent Hydrological Shifts in High-latitude Peatlands
Resource
High-latitude peatlands are changing rapidly in response to climate change, including permafrost thaw. Here, we reconstruct hydrological conditions since the seventeenth century using testate amoeba...
Research as Reciprocity: Northern Cree Community-Based and Community-Engaged Research on Wild Food Contamination in Alberta’s Oil Sands Region
Resource
In this paper, the author suggests that it is possible to participate in research as an act of reciprocity; when a community asks a researcher for help on a specific topic, the application of that...
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...

Survival and Reproduction in Arctic Caribou are Associated with Summer Forage and Insect Harassment
Resource
Investigators have speculated that the climate-driven “greening of the Arctic” may benefit barren-ground caribou populations, but paradoxically many populations have declined in recent years. This...
