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...
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...
Harvesting Can Stabilize Population Fluctuations and Buffer the Impacts of Climate Change

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...
Large Herbivores Facilitate the Persistence of Rare Taxa Under Tundra Warming
Resource
Ecological rarity, characterized by low abundance or limited distribution, is typical of most species, yet our understanding of what factors contribute to the persistence of rare species remains...
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

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...
Sublethal Effects of Parasitism on Ruminants Can Have Cascading Consequences for Ecosystems
Resource
Parasitic infections are common, but how they shape ecosystem-level processes is understudied. Using a mathematical model and meta-analysis, we explored the potential for helminth parasites to trigger...
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...
Video - Managing Soil Carbon in Temperate & Boreal Ecosystems
Resource
This presentation discusses managing soil carbon in temperate and boreal ecosystems.
Video - Nutritional Mechanism Impairs Caribou Pregnancy in the Alberta Oil Sands
Resource
At the 14th North American Caribou Workshop held in September 2012, Jonah Keim presented results of research looking into the impact of nutrition on caribou in the Alberta oil sands region.
Warming Response of Peatland CO2 Sink is Sensitive to Seasonality in Warming Trends

Water Level Drawdown Makes Boreal Peatland Vegetation More Responsive to Weather Conditions
Resource
Abstract Climate warming and projected increase in summer droughts puts northern peatlands under pressure by subjecting them to a combination of gradual drying and extreme weather events. The combined...
