Knock on Wood: Using sound waves and infra-red light to see inside logs and trees

Creator:: Bernart, Bryan
Abstract:: Scientists use sound wave techniques as well as NIR (near infra-red light) to determine the stiffness through density of logs. Featuring Dr. Glen Murphy.

Land-use in the Willamette Valley from 2004-2017

Creator:: Strimbu, Bogdan M., Mueller-Warrant, George, and Trippe, Kristin
Abstract:: The Willamette Valley, bounded on the west by the Coast Range and on the east by the Cascade Mountains, is the largest river valley completely confined to Oregon. The fertile valley soils combined with a temperate, marine climate create ideal agronomic conditions for seed production. Historically, seed cropping systems in...

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...

Dataset associated with Long-Term Effects of Fuel Reduction Treatments on Surface Fuel Loading in the Blue Mountains of Oregon

Creator:: Morici, Kat
Abstract:: Dataset contains a 2015 partial re-measurement of the Blue Mountains Fire and Fire Surrogate study. 8 plots were measured from each of the 16 units, selected randomly from all plots in each unit. Species are recorded using USDA plant codes, "UNKN" is unknown species. For fine fuels, 3 Brown's transects...

A catchment-scale assessment of stream temperature response to contemporary forest harvesting in the Oregon Coast Range

Creator:: Kevin Bladon, Nicholas Cook, Jeffery Light, and Catalina Segura
Abstract:: Historical forest harvesting practices were reviewed in the original Alsea Watershed Study where they found increased energy loading to the stream and produced higher stream temperatures. This was an important early research site that led to the development of contemporary forest management practices to protect water quality and fish habitat...

The Public’s Perception of Fire Prevention and Communication in the Tonto National Forest

Creator:: Lindley, David
Abstract:: As the frequency and intensity of wildfires continue to occur in the West, so does the need for measures intended to improve firefighter safety; public safety; and the protection of property, resources, and wildlife. Furthermore, as human activity in the expanding Wildland Urban Interface increases, so does the need for...

Landscape characteristics and coho salmon (Oncorhynchus kisutch) distributions: explaining abundance versus occupancy

Creator:: Steel, E. A., Jensen, D. W., Burnett, K. M., Christiansen, K., Firman, J. C., Feist, B. E., Anlauf, K. J., and Larsen, D. P.
Abstract:: Distribution of fishes, both occupancy and abundance, is often correlated with landscape-scale characteristics (e.g., geology, climate, and human disturbance). Understanding these relationships is essential for effective conservation of depressed populations. We used landscape characteristics to explain the distribution of coho salmon (Oncorhynchus kisutch) in the Oregon Plan data set, one...

Evidence for xylem embolism as a primary factor in dehydration-induced declines in leaf hydraulic conductance

Creator:: Johnson, Daniel M., McCulloh, Katherine A., Woodruff, David R., and Meinzer, Frederick C.
Abstract:: Hydraulic conductance of leaves (K[subscript leaf]) typically decreases with increasing water stress and recent studies have proposed different mechanisms responsible for decreasing K[subscript leaf]. We measured K[subscript leaf] concurrently with ultrasonic acoustic emissions (UAEs) in dehydrating leaves of several species to determine whether declining K[subscript leaf] was associated with xylem...
