Development of Quantitative PCR Assays to Aid in Root-knot Nematode (Meloidogyne spp.) Diagnostics and Resistance Breeding Efforts in the Pacific Northwest

Creator:: Soule, Michelle L.
Abstract:: In the Pacific Northwest (PNW), the two most common root-knot nematodes are Meloidogyne hapla and Meloidogyne chitwoodi. These nematodes can infect a wide variety of crops and can cause significant losses. Currently, it is common for the field of nematology to use labor-intensive microscopy to identify plant-parasitic nematodes based on...

Evaluating Multi-objective Trade-offs in Mature Douglas-fir (Pseudotsuga menziesii) Stands of Western Oregon

Creator:: Williams, Neil G.
Abstract:: Contemporary forest management involves a more extensive and diverse suite of management objectives than was the case throughout much of the Twentieth Century. Heightened public and political awareness of local and global biodiversity decline, and interest in arresting these trends, has increased the emphasis on broad-based biodiversity conservation as an...

Ecosystem Functions of Pacific Northwest Estuaries: The Role of Ocean and Watershed Drivers in Eelgrass and Coho Salmon Dynamics

Creator:: Magel, Caitlin L.
Abstract:: Interest is expanding for the potential role of estuaries, particularly seagrass and salt marsh habitats, to sequester carbon, mitigate ocean acidification, and support abundant fisheries. The important functions of estuaries are part of a broader set of ecosystem services, or benefits to humans, which are regulated by ocean and watershed...

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...

Ecophysiology of Marine Bivalves : Physiological Rate Processes in Dynamic Environments

Creator:: Gray, Matthew W.
Abstract:: Marine bivalves are globally recognized as ecologically and commercially valuable species and, for over a century, researchers have been studying their feeding, digestion and other related physiological processes. These studies have shown that marine bivalves have complex feeding and particle processing behaviors to maximize growth in dynamic environmental conditions. Additionally,...

Parasitoid wasps of Douglas-fir Needle Midge (Contarinia pseudotsugae Condrashoff,1961) larvae in two Christmas tree farms, Willamette Valley, Oregon

Creator:: Voyvot, Saliha
Abstract:: Douglas-fir needle midge (Contarinia pseudotsugae, Diptera: Cecidomyiidae) is a native invasive species in Pacific Northwest Christmas tree farms, seed orchards, and nurseries where Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) is present. Douglas-fir needle midge (DFNM) causes discoloration and galls on the needles, thereby it affects the market value of the Christmas...

Annual Forages Differ in Response to Partial-Season Irrigation Deficit in Both Spring Seeded and Summer Seeded Cropping Systems

Creator:: Fan, Qianqian
Abstract:: Water scarcity during summer becomes a serious problem in the Pacific Northwest, threatening forage production provided to livestock. Annual forages show great potential in handling drought because of their flexibility in seeding date and short growing season, and can shift the production to periods of feed shortage and fill the...

The Impact of Disturbance on Carbon Stores and Dynamics in Forests of Coastal Alaska

Creator:: Yatskov, Mikhail A.
Abstract:: Changes in climate caused by increased concentrations of carbon dioxide (CO₂) in the Earth’s atmosphere have led land and ocean surface temperatures to increase by 0.85°C and sea level to increase by 19 cm relative to preindustrial times. Global climate change will lead to further alterations in mean temperature and...

Evaluating pollinator populations and lamb productivity from simple, diverse, and legume pastures in a dual use pasture system

Creator:: Caudillo, Mia C.
Abstract:: Dual use pasture systems, sometimes referred to as dual purpose pasture systems, take advantage of the land being used to maximize multiple outputs from a single area. Developing a system to support both production of grazing livestock as well as pollinator health is of increasing importance in pasture-based farming systems....

Wading through Space and Time: Leveraging Geospatial Methods to Better Understand Recreation Behavior, Experience, and Impacts within a Densely Used Lake Destination

Creator:: Baker, Jenna T.
Abstract:: In the last decade, many U.S. parks and protected areas (PPA) experienced record breaking visitation levels. Managers of these PPAs face the challenging task of providing a range of quality and accessible outdoor experiences without compromising the integrity and health of surrounding ecosystems. Understanding how PPA visitors move and interact...
