Assessing the Cumulative Impacts of Forest Management on Forest Age Structure Development and Woodland Caribou Habitat in Boreal Landscapes: A Case Study from Two Canadian Provinces
Resource
The Canadian boreal forest biome has been subjected to a long history of management for wood production. Here, we examined the cumulative impacts of logging on older forests in terms of area...
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...

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...
Climate Change Alone Cannot Explain Boreal Caribou Range Recession in Quebec Since 1850
Resource
Abstract The contraction of species range is one of the most significant symptoms of biodiversity loss worldwide. While anthropogenic activities and habitat alteration are major threats for several...
Demographic Responses of Boreal Caribou to Cumulative Disturbances Highlight Elasticity of Range-specific Tolerance Thresholds
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...
Drivers of Vegetation Regrowth on Logging Roads in the Boreal Forest: Implications for Restoration of Woodland Caribou Habitat
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...
Ecosystem Management in Paludified Boreal Forests: Enhancing Wood Production, Biodiversity, and Carbon Sequestration at the Landscape Level
Resource
Canada’s boreal forest represents an important contributor of the world’s wood supply industry. However, maintaining or increasing productivity of the boreal forest may be challenging in areas...
Global Change Risks a Threatened Species due to Alteration of Predator–prey Dynamics
Resource
Although global change can reshape ecosystems by triggering cascading effects on food webs, indirect interactions remain largely overlooked. Climate- and land-use-induced changes in landscape cause...
Management-mediated Predation Rate in the Caribou–Moose–Wolf System: Spatial Configuration of Logging Activities Matters
Resource
Landscape complexity can determine the population dynamics of interacting predators and prey. Yet, management plans are commonly developed from aspatial predictive models. This oversight may result in...
Perfluoroalkyl Substances in Circum-Arctic Rangifer: Caribou and Reindeer
Resource
Livers of caribou and reindeer (Rangifer tarandus) from Canada (n = 146), Greenland (n = 30), Svalbard (n = 7), and Sweden (n = 60) were analyzed for concentrations of eight perfluoroalkyl carboxylic...
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...

Spatial and Temporal Variation in Forest Transpiration Across a Forested Boreal Peatland Complex
Resource
Transpiration is a globally important component of evapotranspiration. Careful upscaling of transpiration from point measurements is thus crucial for quantifying water and energy fluxes. In spatially...
The Essential Carbon Service Provided by Northern Peatlands
Resource
Northern peatlands have cooled the global climate by accumulating large quantities of soil carbon (C) over thousands of years. Maintaining the C sink function of these peatlands and their immense long...
Webinar - Towards Understanding the Influence of Headwater Catchments on Water Availability in the Athabasca River Basin
Resource
This presentation highlights the importance of northern Alberta’s “mountains” and wetlands on sustaining water flows in local streams and regional rivers in the Athabasca River Basin.
