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...

Recent Climate Change has Driven Divergent Hydrological Shifts in High-latitude Peatlands
Resource
High-latitude peatlands are changing rapidly in response to climate change, including permafrost thaw. Here, we reconstruct hydrological conditions since the seventeenth century using testate amoeba...
Submersed Macrophyte Density Regulates Aquatic Greenhouse Gas Emissions
Resource
Shallow freshwaters release large amounts of greenhouse gases. These shallow waterbodies are often dominated by submersed plants, yet the role these plants have in affecting greenhouse gas release is...
