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...

Cloning, sequencing and aflatoxin B₁ metabolism by multiple rainbow trout CYP1A cDNAs expressed in yeast

Creator:: You, Lijing
Abstract:: Previous reports indicate the presence of multiple CYP1A sequences in rainbow trout, but their functional differences are unknown. This report describes the cloning and partial characterization of four trout CYP1A cDNAs, which are given the tentative designations CYP1A1v2, v3, v4, and v5. Comparison among these four and three previously reported...

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...

The influence of forest management on headwater stream amphibians at multiple spatial scales

Creator:: Stoddard, Margo A.
Abstract:: To effectively manage for biodiversity at broad, ecosystem scales, the influences of habitat structure at multiple spatial scales on vertebrate species must be understood. There are few studies on the broad-scale habitat requirements of stream amphibians despite their importance in streams in forest ecosystems in the Pacific Northwest (PNW) as...

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...

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...

Modelling Early-Seral Vegetation Dynamics Using Climate and Soil Moisture

Creator:: Guevara, Claudio A.
Abstract:: Forest plantations in the Pacific Northwest are highly productive and have been intensively managed to maximize tree growth with practices such as Forest Vegetation Management (FVM). Different FVM regimes have been shown to enhance forest establishment by reducing the competition between the planted seedlings and early-seral vegetation. To better understand...

Re‐establishment of the native oyster, Ostrea conchaphila, in Netarts Bay, Oregon, USA

Creator:: Archer, Pamela Emily
Abstract:: Olympia oysters, “Ostrea conchaphila,” were once common along the west coast of North America. A popular delicacy, native oyster populations began to decline in the late 1800’s due to over‐harvest, degraded water quality, and habitat loss. Interest in re‐establishing the native oyster in a small Oregon estuary, Netarts Bay, culminated...
