Alder Distribution and Expansion Across a Tundra Hillslope: Implications for Local N Cycling

Alder Distribution and Expansion Across a Tundra Hillslope: Implications for Local N Cycling

Increases in the availability of nitrogen (N) may have consequences for plant growth and nutrient cycling in N-limited tundra plant communities. We investigated the impact alder (Alnus viridis spp. fruticosa), an N-fixing deciduous shrub, has on tundra N cycling at a hillslope located on Alaska’s Se...
