Effects of permafrost thaw on nitrogen availability and plant–soil interactions in a boreal Alaskan lowland

1. Increasing rates of permafrost thaw in boreal peatlands are converting conifer forests to water-logged open wetlands. Permafrost thaw increases soil nitrogen (N) availability, but it is unclear whether such changes are due solely to changes in surface soil N mineralization or N mobilization from...
