Wood density of young-growth western hemlock: relation to ring age, radial growth, stand density, and site quality

Creator:: DeBell, Dean S., Singleton, Ryan, Gartner, Barbara L., and Marshall, David D.
Abstract:: Breast-high stem sections were sampled from 56 western hemlock (Tsuga heterophylla (Raf.) Sarg.) trees growing in 15 plots representing a wide range of tree and site conditions in northwestern Oregon. Growth and wood density traits of individual rings were measured via X-ray densitometry, and relationships of ring density and its...

Wood density and fiber length in young populus stems: relation to clone, age, growth rate, and pruning

Creator:: DeBell, Dean S., Singleton, Ryan, Harrington, Constance A., and Gartner, Barbara L.
Abstract:: Cross-sectional disks were cut at two stem heights (1.5 m and 3.0 m) from 9-year-old trees of three Populus clones grown in an intensively-cultured plantation in western Washington. At age 1.5 years, when the trees averaged 3.4 m tall, half of the trees were pruned by removing all branches below...

Scholz thesis Final Paper (final)[1].pdf

Creator:: Scholz, Ryan
Abstract:: Studies were conducted to assess influencing the effectiveness of sheep for grazing control of false brome (Brachypodium sylvaticum) an invasive grass species. Orphan lambs were exposed to false brome via grass extract in their milk and naturally reared lambs were exposed by grazing dense stands of false brome with their...

Geomagnetic field influences upward movement of young Chinook salmon emerging from nests

Creator:: Putman, Nathan F., Scanlan, Michelle M., Pollock, Amanda M., O'Neil, Joseph P., Couture, Ryan B., Stoner, Joseph S., Quinn, Thomas P., Lohmann, Kenneth J., and Noakes, David L.
Abstract:: Organisms use a variety of environmental cues to orient their movements in three-dimensional space. Here, we show that the upward movement of young Chinook salmon (Oncorhynchus tshawytscha) emerging from gravel nests is influenced by the geomagnetic field. Fish in the ambient geomagnetic field travelled farther upwards through substrate than did...

Economics of oilseed crops and their biodiesel potential in Oregon's Willamette Valley

Creator:: Jaeger, William K. and Siegel, Ryan
Abstract:: This study assesses the economic potential of biodiesel production in the Willamette Valley for six oilseeds as potential feedstocks: canola, flax, camelina, yellow mustard, sunflower, and safflower. We evaluate costs and returns from feedstock production, oilseed crushing, and biodiesel processing. Our analysis is based on the best available information on...

Strain-resolved microbial community proteomics reveals simultaneous aerobic and anaerobic function during gastrointestinal tract colonization of a preterm infant

Creator:: Brooks, Brandon, Mueller, Ryan S., Young, Jacque C., Morowitz, Michael J., Hettich, Robert L., and Banfield, Jillian F.
Abstract:: While there has been growing interest in the gut microbiome in recent years, it remains unclear whether closely related species and strains have similar or distinct functional roles and if organisms capable of both aerobic and anaerobic growth do so simultaneously. To investigate these questions, we implemented a high-throughput mass...

Age systematics of two young en echelon Samoan volcanic trails

Creator:: Koppers, Anthony A. P., Russell, Jamie A., Roberts, Jed, Jackson, Matthew G., Konter, Jasper G., Wright, Dawn J., Staudigel, Hubert, and Hart, Stanley R.
Abstract:: The volcanic origin of the Samoan archipelago can be explained by one of three models, specifically, by a hot spot forming over a mantle plume, by lithospheric extension resulting from complex subduction tectonics in the region, or by a combination of these two processes, either acting sequentially or synchronously. In...

Understanding the Role of Government and Buyers in Supplier Energy Efficiency Initiatives

Creator:: Wu, Zhaohui, Ellram, Lisa M., and Schuchard, Ryan
Abstract:: In environmental management, companies must respond to myriad needs and pressures from stakeholders such as buyers, regulators, communities and NGOs. While researchers recognize that these stakeholder entities have different saliency and influences over a focal firm, the influences from multiple stakeholders are often aggregated as a single factor, overlooking differences...

Density, ages, and growth rates in old-growth and young-growth forests in coastal Oregon

Creator:: Tappeiner, John C., Huffman, David W. (William), 1962-, Marshall, David, Spies, Thomas A., and Bailey, John D.
Abstract:: We studied the ages and diameter growth rates of trees in former Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) old-growth stands on 10 sites and compared them with young-growth stands (50-70 years old, regenerated after timber harvest) in the Coast Range of western Oregon. The diameters and diameter growth rates for the...
