How Safe are the Woods?: Researchers tackle tough problems

Creator:: Moldenke, Alison
Abstract:: The dangers for National Park Service rangers have been increasing. Scientists study psychology, sociology, and recreation resources to help balance the dangers of crime and hazards with the increase in demand for outdoor recreation. Featuring Dr. Jo Tynon.

Lewis and Clark in the Lab: Journals from the Corps of Discovery aid wildlife scientists

Creator:: Davis, Caryn
Abstract:: For a long time historians have looked at Lewis and Clark's journals as important sources. Now scientists are doing the same to learn about the Pacific Northwest before white settlement. Featuring: Dr. Andrea Laliberte and Dr. William Ripple

Time dependence of triplet-singlet excitation transfer from compact poly rA to bound dye at 77 K

Creator:: Pearlstein, R. M., Van Nostrand, F., and Nairn, J. A.
Abstract:: The nonexponential phosphorescence decay of a highly folded form of poly-riboadenylic acid (poly rA) with noncovalently bound dye is explained by a novel application of a well-known theory of electronic excitation transfer based on the Förster mechanism. This theory, originally used to describe singlet-singlet energy transfer from donor molecules to...

Analysis of metal-plate-connected wood trusses with semi-rigid joints

Creator:: Gupta, R., Gebremedhin, K. G., and Cook, J. R.
Abstract:: Metal-plate-connected wood trusses with semi-rigid joints were investigated by the matrix method of structural analysis. The element-stiffness matrix and fixed-end forces of an individual member with one or both ends semi-rigid were derived as modifications of the idealized cases. The case of unequal elastic connections at two ends of a...

Early growth of Douglas-fir in a reciprocal planting

Creator:: Ching, Kim K. and Oregon State University. Forest Research Laboratory
Abstract:: Survival and growth during three years at 8 out-planting areas are reported for Douglas-fir from 14 sources of seed. Early survival was highest near Nimpkish on Vancouver Island. At most plantations, trees from the local seed source grew as well as did those from the best three sources. Trees from...

Toward biologically meaningful net carbon exchange estimates for tall, dense canopies: Multi-level eddy covariance observations and canopy coupling regimes in a mature Douglas-fir forest in Oregon

Creator:: Thomas, Christoph K., Martin, Jonathan G., Law, Beverly E., and Davis, Kent
Abstract:: We sought to improve net ecosystem exchange (NEE) estimates for a tall, dense, mature Douglas-Fir forest in the Oregon Coast range characterized by weak flows, systematic wind directional shear, and limited turbulent mixing throughout the diurnal period. We used eddy covariance (EC) observations at two levels and concurrent biological measurements...

Complex restoration challenges: Weeds, seeds, and roads in a forested Wildland Urban Interface

Creator:: Buonopane, Michelle, Snider, Gabrielle, Kerns, Becky K., and Doescher, Paul S.
Abstract:: Federal policies in the US strongly emphasize reducing hazardous fuels at the Wildland Urban Interface (WUI). However, these areas present restoration challenges as they often have exotic weeds, frequent human disturbance, and the presence of roads. Understanding seed banks is important in planning for desirable post-disturbance community conditions, developing integrated...

Bibliography of Douglas-fir provenance studies, 1907-1974

Creator:: Hermann, Richard K., Ching, Kim K., and Oregon State University. Forest Research Laboratory
Abstract:: Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) is one of the world's most important and valuable timber trees. Its natural distribution in North America resembles an inverted V with uneven sides. From the apex in British Columbia, the western half extends along the Pacific mountain ranges into California for about 2,200 km...
