Summer Low Flow Response to Timber Harvest and Riparian Treatments in Forested Headwater Streams of Coastal Northern California

Creator:: Nicholas, Jonah
Abstract:: Headwater streams represent the majority of the drainage area of a river network and provide many critical functions supporting aquatic and terrestrial ecosystem health. The riparian zones that surround these streams are transitional areas between terrestrial and stream ecosystems, which provide key habitat for aquatic and terrestrial organisms, especially during...

Limiting copper loss from treated wood in or near aquatic environments

Creator:: Mitsuhashi Gonzalez, June M.
Abstract:: Copper migration from treated wood has created concerns within the environmental community because of the potential effects of this heavy metal on aquatic organisms. Migration can be limited, to some extent, by more controlled treatments and by post-treatment processing, but these actions cannot completely overcome the problem. An alternative approach...

Chemical modification of wood : dimensional stabilization of viscoelastic thermal compressed wood

Creator:: Gabrielli, Christopher P.
Abstract:: The tendency of wood to shrink and swell with changing moisture content remains as one of the most significant challenges to using wood in its many applications. Viscoelastic Thermal Compression (VTC) has been shown to significantly increase the density, strength and stiffness of wood. However, dimensional stability is still a...

Histological examination of Phytophthora ramorum in Notholithocarpus densiflorus bark tissues

Creator:: Botts, Molly M.
Abstract:: Colonization of N. densiflorus tissues by P. ramorum is not well understood. The pathogen is able to colonize nearly all tissues of this host but it is unclear how a tree is ultimately killed. Because this is such a destructive invasive pathogen, it is important to investigate its pathogenic strategy....

Using Vineyard Floor Management to Manipulate Vine Vigor: Impacts on 'Pinot noir' Yield Productivity and Fruit Composition

Creator:: Reeve, Alison L.
Abstract:: Winegrapes are an important crop for Oregon agriculture, ranking amongst the top ten agricultural commodities based on farmgate value. The most widely planted winegrape cultivar in the state is ‘Pinot noir’ (Vitis vinifera L.), and the majority of acreage is produced in the Willamette Valley. Production of quality ‘Pinot noir’...

Douglas-fir Seedlings in the Pacific Northwest: The Genetics of Drought Adaptation

Creator:: Celer, Erda
Abstract:: Douglas-fir (Pseudotsuga menziesii) is a widely distributed, ecologically important, and commercially valuable tree species in North America. However, climate change is expected to adversely impact Douglas-fir trees, and assisted migration may become necessary to lessen the effects of climate change. Because drought stress is one of the projected effects of...

In-forest log segregation based on acoustic measurement of wood stiffness

Creator:: Amishev, Dzhamal Y.
Abstract:: To remain competitive, the forest products industry needs to look for new and innovative processes and technologies to not only reduce costs but also to recover more value through the entire seedling-to-customer forest products supply chain. It is well recognized that measuring wood properties of logs in real time during...

Ecology and biological control of an apomictic invasive plant, Chondrilla juncea (Asteraceae)

Creator:: Campanella, Donald M.
Abstract:: A study consisting of three parts was undertaken to investigate how variation in species interactions, population genetic structure, epidemiological parameters, and plant breeding system may influence the ecology and biological control of an apomictic invasive plant, Chondrilla juncea (Asteraceae). Interactions between natural enemy species may modify their net effect on...

Interactions between nitrogen, phosphorus, and molybdenum in forest soils and cyanobacterial lichen in the Oregon Coast Range

Creator:: Marks, Jade A.
Abstract:: Molybdenum is an essential component of biogeochemical cycling, most notably as a component of the nitrogenase enzyme used in biological nitrogen (N) fixation. While the important role of phosphorus (P) in limiting N fixation in ecosystems has been well documented, occurrence and prevalence of molybdenum (Mo) limitation is largely unknown....

Development of rapid visual screening tool for seismic evaluation of wood-frame dwellings

Creator:: Lucksiri, Kraisorn
Abstract:: During the past several decades, earthquakes have caused extensive damage to buildings, including wood-frame, single-family dwellings, in the United States. In order to mitigate future losses, existing buildings in earthquake prone areas should be evaluated for their seismic safety. This is also an important issue for buildings in Oregon due...
