Capturing the variation in Arctic plant functional traits.
How will warming and permafrost thaw will affect above- and belowground plant functional traits, and what are the consequences for Arctic ecosystem carbon, energy, water, and nutrient fluxes?
This work is being conducted across hillslope gradients across southerly tundra sites near Nome, AK, on the Seward Peninsula. We acknowledge and are deeply grateful to UIC Science and the Council Native Corporation, Mary’s Igloo Native Corporation, and Sitnasuak Native Corporation for allowing us to conduct our research on their land.
Check out my colleague, Dr. Verity Salmon’s, website for even more details on our cool tundra science!
