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...
Plant Mercury Accumulation and Litter Input to a Northern Sedge-dominated Peatland
Resource
Abstract Plant foliage plays an essential role in accumulating mercury (Hg) from the atmosphere and transferring it to soils in terrestrial ecosystems, and many studies have focused on forested...
Response of CO2 and CH4 Emissions from Arctic Tundra Soils to a Fultifactorial Manipulation of Water Table, Temperature, and Thaw Depth
Resource
Significant uncertainties persist concerning how Arctic soil tundra carbon emission responds to environmental changes. In this study, 24 cores were sampled from drier (high centre polygons and rims)...
