Bees of the Pacific Northwest : key to bumble bee species for females (Hymenoptera : Apidae : Bombus)

Creator:: Best, Lincoln R., Dunlap, Joshua B., Jackson, August S., Rivers, James W., and Williams, Paul H.
Abstract:: This species key to female bumble bees of the Pacific Northwest provides dichotomous couplets which aid the user in identifying 27 species which occur or have occurred historically, and may still be present in the region. The key architecture is based strongly on the key to species for females found...

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...

Ability of natural extracts to limit mold growth on Douglas-fir sapwood

Creator:: Maoz, Michal, Karchesy, Joseph J., and Morrell, Jeffrey J.
Abstract:: The ability of selected plant extracts from wood and foliage to inhibit mold regrowth on fungal colonized wood was evaluated on Douglas-fir sapwood. Most foliage extracts produced some inhibition of Graphium or Trichoderma species, but isolations of other fungi increased following treatment. Five out of eight wood extracts produced 50%...

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...

Microcomputer applications in timber management and accounting

Creator:: Karas, Joseph, Ryan, Joan S., Rosette, Marvin, Oregon State University. College of Business, and Oregon State University. College of Forestry
Abstract:: The purpose of this monograph is to acquaint the reader with some possible uses of a microcomputer in timber management and accounting. Examples will illustrate the basic structure of an overall timber management and accounting system. The information contained in this monograph is tailored to the needs of the small,...

Applying the dual-isotope conceptual model to interpret physiological trends under uncontrolled conditions

Creator:: Barnard, H. R., Brooks, J. R., and Bond, B. J.
Abstract:: The inter-relationships among δ¹³C and δ¹⁸O in tree ring cellulose and ring width have the potential to illuminate long-term physiological and environmental information in forest stands that have not been monitored. We examine how within-stand competition and environmental gradients affect ring widths and the stable isotopes of cellulose. We utilize...

Metal-plate-connected wood joints : a literature review

Creator:: Gupta, Rakesh, Vatovec, Milan, Miller, Thomas H., and Oregon State University. Forest Research Laboratory
Abstract:: "This publication has presented an overview of current research on MPC joints in wood trusses. The literature search was primarily of U.S. sources, with some effort to obtain literature from other parts of the world. An enormous amount of important information has been amassed by studies on testing procedures and...
