Ethanol in Douglas-fir with black-stain root disease (Leptographium wageneri)

Creator:: Kelsey, Rick G. and Joseph, Gladwin
Abstract:: Diseased and healthy Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) were identified at two black-stain root disease centers, caused by Leptographium wageneri var. pseudotsugae Harrington & Cobb, in the Oregon Coast Range near Coos Bay. Phloem and sapwood near the root collar were sampled monthly for 1 year, whereas roots were sampled...

Burning the legacy? Influence of wildfire reburn on dead wood dynamics in a temperate conifer forest

Creator:: Donato, Daniel C., Fontaine, Joseph B., and Campbell, John L.
Abstract:: Dynamics of dead wood, a key component of forest structure, are not well described for mixed-severity fire regimes with widely varying fire intervals. A prominent form of such variation is when two stand-replacing fires occur in rapid succession, commonly termed an early-seral “reburn.” These events are thought to strongly influence...

An integrated approach using Bacillus subtilis B26 and essential oils to limit fungal discoloration of wood

Creator:: Wang, Yu, Chang, Jianmin, Morrell, Jeffrey J., Freitag, Camille M., and Karchesy, Joseph J.
Abstract:: Bacillus subtilis and essential oils have been explored separately for their ability to limit colonization by wood stain and mold fungi, but neither approach has been completely effective. One alternative strategy would be to combine the bacterial biocontrol with one or more natural products extracts. In this report, the ability...

Antioxidant activity of fractions from Quercus sideroxyla bark and identifi cation of proanthocyanidins by HPLC-DAD and HPLC-MS

Creator:: Rosales-Castro, Martha, Gonzalez-Laredo, Ruben Francisco, Rocha-Guzman, Nuria Elizabeth, Gallegos-Infante, Jose Alberto, Rivas-Arreola, Maria Jose, and Karchesy, Joseph J.
Abstract:: The most active phenolics in Quercus sideroxyla Humb. & Bonpl. residual bark were identified and evaluated following a chromatographic fractionation. Bark powder was defatted with hexane and crude extract (CE) was obtained by extraction with aqueous acetone (70%). A liquid partition with ethyl acetate was performed to produce an organic...

Leaf litter chemistry controls on decomposition of Pacific Northwest trees and woody shrubs

Creator:: Valachovic, Y. S., Caldwell, B. A., Cromack Jr., K., and Griffiths, Robert P.
Abstract:: The effects of initial leaf litter chemistry on first-year decomposition rates were studied for 16 common Pacific Northwest conifers, hardwoods, and shrubs at the H.J. Andrews Experimental Forest in western Oregon. Leaf litters were analyzed for C, N, P, K, Ca, Mg, proximate organic fractions (nonpolar, polar, acid-hydrolyzable extractives, acid-hydrolyzable...
