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...
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...
Flexible migration by woodland caribou in Ontario, Canada
Resource
Abstract Recent studies of ungulate movement ecology suggest that seasonal movement tactics often vary within a population. The forest-tundra and forest-dwelling ecotypes of woodland caribou (...
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...
Inuit Qaujimajatuqangit about Population Changes and Ecology of Peary Caribou and Muskoxen on the High Arctic Islands of Nunavut
Project
Organization:
This master's project collected and documented Inuit observations to describe the population distribution of caribou and muskoxen in Nunavut.
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...
Remediation of Hydrocarbon Contaminated Soils in the Canadian Arctic by Landfarming
Resource

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 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 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 SEEDS Organic Puck: An Innovative System for Establishing Native Plants on Disturbed Sites
Resource
The SEEDS project objective is to develop and test a seed delivery technology that improves emergence and early establishment of native plants for the reclamation of disturbed boreal forest sites.
