Plant community dynamics across a gradient of polygonal tundra.
In 2012 and 2013, we investigated the relationships among plant community composition, above- and belowground biomass and nitrogen content, and edaphic and environmental conditions, and how these relationships changed across a gradient of polygonal tundra in Utqiagvik (formerly Barrow), AK.
