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...
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)...
Tracking Vegetation Transitions Due to Invasion of Cattail (Typha) in Lake Superior Coastal Peatlands
Resource
Invasive cattails ( Typha angustifolia and Typha × glauca) pose a problem for many Laurentian Great Lakes wetlands, especially sedge/grass meadows. In western Lake Superior, early signs of invasion...
