Water movement in the stem xylem in relation to xylem specific conductivity in four hardwood species

Creator:: Fallas-Cedeño, Lottie
Abstract:: In deciduous species, water exits stems mainly through leaf traces attached to the outer growth ring and yet we know that water ascends throughout the entire cross-section of the sapwood. There is an increasing amount of information on sap flow and sapwood hydraulic properties from separate studies, but little information...

Identifying the relevance of "family forest" wood product origin and environmental certification for Oregon consumers, and specifiers and industrial customers

Creator:: Hamner, Rebecca A.
Abstract:: The wood products industry is influenced heavily by family ownership along the entire value chain. Although family ownership affects each link of the wood products value chain, there has been little research into the importance of products originating from family forestland. Specific attributes of products, such as origin or environmental...

Characterization of Fungal Endophyte Populations in Ponderosa Pine (Pinus ponderosa) Needles in The B&B Fire Complex of The Eastern Cascade Mountain Range

Creator:: Scrivani, James V.
Abstract:: Forests are some of the most ecologically diverse and dense habitats on the planet. Research shows that the endophyte community, or the fungi, bacteria, and viruses within a forest ecosystem is highly diverse. Fungal endophytes are defined as fungi that live within the tissues of host plants. Relationships between fungal...

Remote sensing of forest biomass dynamics using Landsat-derived disturbance and recovery history and lidar data

Creator:: Pflugmacher, Dirk
Abstract:: Improved monitoring of forest biomass is needed to quantify natural and anthropogenic effects on the terrestrial carbon cycle. Landsat's temporal and spatial coverage, fine spatial grain, and long history of earth observations provide a unique opportunity for measuring biophysical properties of vegetation across large areas and long time scales. However,...

An examination of several methods of quantifying forest structure in headwater riparian forests of western Oregon

Creator:: Haxton, Zane A.
Abstract:: Headwater streams are generally small, first-order streams that can comprise up to 80% (by stream length) of the drainage network in mountainous areas of the Pacific Northwest. These streams are intimately connected with downstream reaches, serving as a source of sediment, woody debris, organic matter and nutrients. The surrounding forests...

Effects of release from suppression on hydraulic architecture, photosynthetic capacity and functional wood characteristics in Douglas-fir and western hemlock

Creator:: Renninger, Heidi
Abstract:: Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), a shade intolerant species, and western hemlock (Tsuga heterophylla (Raf.) Sarg.), a shade tolerant species, were compared to learn more about the temporal pattern of release from suppression in both species, whether hydraulic architecture or photosynthetic capacity constrain release and how wood functional properties change...

Phylogenetic Identification of Pathogenic and Endophytic Fungal Populations in West Coast Douglas-fir (Pseudotsuga menziesii) Foliage

Creator:: Daniels, Hazel A.
Abstract:: Douglas-fir provides social, economic, and ecological benefits in the Pacific Northwest (PNW). In addition to timber, forests support abundant plant and animal biodiversity and provide socioeconomic viability for many rural communities. Products derived from Douglas-fir account for approximately 17% of the U.S. lumber output with an estimated value of $1.9...

Toxicity of Fungal Pigments from Chlorociboria spp. and Scytalidium spp.

Creator:: Almurshidi, Badria H.
Abstract:: Commercial methodologies for producing fungal pigments are of worldwide interest due to the desire to move away from synthetic dyes. Chlorociboria species and Scytalidium species have been reported to produce sufficient yields of pigments for commercial production and have attracted special attention because of their use in spalted wood applications....

Evaluating the rates of nitrate removal for a nitrate containing, low organic carbon wastewater interacting with carbon-containing solid substrates

Creator:: Hart, Jeffrey L.
Abstract:: The primary objective of this study was to evaluate the rates of nitrate removal for a nitrate containing, low organic carbon wastewater interacting with four different carbon-containing solid substrates (alder woodchips, corn silage, manure and woodchip biochar). Batch systems were tested for nitrate removal, and systems with a combination of...

The Effect of Downed-trees on Harvesting Productivity and Costs in Beetle-killed Stands

Creator:: Kim, Yaejun
Abstract:: The mountain pine beetle has impacted over 5 million hectares of pine forests in the Rocky Mountains region in the United States. Although some beetle-killed stands are available for salvage harvesting, there are many uncertainties in harvesting beetle-killed stands including safety, costs, recoverable products and their values. These uncertainties impose...
