Abstract
Elevated CO2 and temperature effects on ectomycorrhizal diversity were studied during the first part of a 3-4 year exposure using Douglas-fir seedlings. Ectomycorrhizae (ECM) are sorted into morphotypes by gross morphology. Number of ECM tips and number of morphotypes increased as exposure progressed indicating adjustment from nursery to native soil. Treatments may affect number of tips in the Rhizopogon morphotypes differentially by season. Simpson's index changed by season and was affected by temperature. Morphotype diversity as the exposure continues may affect dominance of the Rhizopogon sp. group.
