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...
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...

On the Role of Peat Bogs as Components of Indigenous Cultural Landscapes in Northern North America
Resource
This article explores uses of peat bogs and associated plants and other resources by drawing on the published ethnobotanical and archeological literature pertaining to Indigenous groups that lived 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...
What Happened to the Beverly Caribou Herd after 1994?
Resource
The Beverly herd was one of the first large migratory herds of barren-ground caribou ( Rangifer tarandus groenlandicus) defined in northern Canada on the basis of annual return of breeding females to...
