Research Highlight: A canopy shift in interior Alaskan boreal forests: Consequences for above- and belowground carbon an dnitrogen pools during post-fire succession

Novus steering committee member Michelle Mack (Northern Arizona University) and Novus participant Heather Alexander (University of Texas, Brownsville) recently published a study on the effects of post-fire successional patterns on nutrient cycling in boreal forests of Alaska. The authors found that deciduous successional trajectories favored aboveground storage of carbon and nitrogen, while spruce-dominated successional patterns stored more carbon and nitrogen in the soil organic layer. This difference in storage pool increases longevity of carbon and nitrogen and may result in a negative feedback to climate warming impacts on nutrient cycling.
