We are investigating how the traits of trees and their associated microbes influence biogeochemical differences that exist within and among forests. We hypothesize that trees that associate with arbuscular mycorrhizal (AM) fungi alter nutrient and carbon cycling differently than trees that associate with ectomycorrhizal (ECM) fungi. We refer to this as the Mycorrhizal-Associated Nutrient Economy (or MANE) framework, and have been investigating whether the relative abundance of AM and ECM trees in a stand contributes to unique “biogeochemical syndromes” in terms of energy transformations and nutrient cycling.
