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...

Fall Supplemental Feeding Increases Population Growth Rate of an Endangered Caribou Herd
Resource
Our results support the recommendation that multiple management actions should be implemented to improve recovery prospects for caribou.
Intrinsic Traits of Woodland Caribou Rangifer tarandus Calves Depredated by Black Bears Ursus americanus and Coyotes Canis latrans
Resource
Individuals in substandard physical condition are predicted to be more vulnerable to predation. Support for this prediction is inconsistent partly as a result of differences across systems in the life...
Large Animal Models for Chronic Wasting Disease
Resource
Chronic wasting disease (CWD) is a fatal neurodegenerative prion disease of cervid species including deer, elk, moose and reindeer. The disease has shown both geographic and species expansion since...
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...
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...
Saving Endangered Species Using Adaptive Management
Resource
Adaptive management is a powerful means of learning about complex ecosystems, but is rarely used for recovering endangered species. Here, we demonstrate how it can benefit woodland caribou, which...
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 Tree Ring Analysis to Determine Impacts of a Road on a Boreal Peatland
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...
Webinar - Establishing Vegetation on Constructed Fens in Alberta's Oil Sands Region
Resource
Oil sands mining in Alberta has disturbed large areas of peatlands, the dominant regional ecosystem type, and no formal strategies exist to reconstruct the landscape. Peatland reclamation is...
Wetland Restoration: Can Short-Term Success Criteria Predict Long-Term Outcomes?
Resource
Worldwide wetland loss over the past 50 years has made wetland conservation a public policy priority, leading to an increase in wetland restoration programs. However, predicting long-term restoration...
