Fungal diversity within decomposing woody conifer roots in Oregon

Creator:: Vandegrift, V. Eleanor
Abstract:: Previous studies have indicated that roots from five tree species (Picea sitchensis, Tsuga heterophylla, Pseudotsuga menziesii, Pinus ponderosa, and Pinus contorta) decompose at different rates across an environmental gradient in Oregon. Measurements of wood chemistry from each tree species as well as moisture and temperature from each location do not...

Impact of Armillaria and annosus root diseases on stand and canopy structure, species diversity, and down woody material in a central Oregon mixed-conifer forest

Creator:: Fields, Kristen L. N.
Abstract:: White and grand fir are both valuable components of the mixed-conifer stand structure managed for late-successional reserves in central Oregon. However, they are often short-lived species because of high susceptibility to root diseases, defoliating insects, bark beetles, and wildfire. This study focuses on the effects of root diseases caused by...
