Nutrient Profile and Nursery Feeding Damage of Halyomorpha halys (Hempitera: Pentatomidae)

Creator:: Skillman, Victoria P.
Abstract:: Halyomorpha halys Stål, brown marmorated stink bug or BMSB, is now present in 43 US states. A native of eastern Asia, this pest can feed on ~200 different plant species damaging bark, leaves, buds, stems, and fruits. Many of these plant species include wild plants, ornamentals, and agricultural crops. BMSB...

Life-Cycle and Playability Analysis of Natural Turfgrass and Synthetic Infill Playing Surfaces Under Field Conditions

Creator:: Daviscourt Brian L.
Abstract:: The perception of a long-term cost advantage of synthetic infill turf systems relative to natural grass systems has contributed to a rise in their popularity in the USA. However, few comprehensive cost assessments of natural grass and synthetic infill systems exist. There are also no studies looking at interactions between...

Response of Roughstalk Bluegrass (Poa trivialis L.) to Waterlogging Stress

Creator:: Liu, Mingyang
Abstract:: Roughstalk bluegrass (Poa trivialis L.) (RB) is a weed species that increased very quickly in grass seed production fields of the Willamette Valley. The invasion of RB in grass seed crops often occurs in waterlogged soils. In waterlogged areas, RB exhibited better competitiveness and had greater population densities than other...

A Comparative Study of Foraging Behavior and Disturbance Regimes in Urban Versus Agricultural Habitats used by Cackling Geese Wintering in the Willamette Valley, Oregon

Creator:: Harrington, Erin R.
Abstract:: The Cackling goose (Branta hutchinsii minima) population has increased from a low of 20,000 in 1984 to the current population of 220,000-300,000 (Stehn 2012, Sanders 2013). As the Cackling goose population began to recover in the late 1990s, the majority of the population relocated from wintering in California to the...

New Applications for Passive Samplers : In-situ Flux and Risk Assessment of Legacy and Emerging Contaminants

Creator:: Tidwell, Lane G.
Abstract:: Passive sampling devices (PSDs) were used to measure air vapor and water dissolved phase concentrations of polycyclic aromatic hydrocarbons (PAHs) and oxygenated PAHs (OPAHs) at two different environmentally contaminated sites. Environmental contaminates like PAHs and OPAHs are present in both the atmospheric and aqueous environmental compartments. It is known that...

Dynamics of Zymoseptoria tritici Fungicide Resistance in the Willamette Valley of Oregon

Creator:: Hagerty, Christina H.
Abstract:: The development of resistance to multiple fungicide classes is currently limiting disease management options for many pathogens, while the discovery of new fungicide classes has become less frequent. To address this pressing issue, a three-part study with different layers of complexity, objectives, and experimental approaches was conducted using the model...

Overstory Structure and Community Characteristics of Oregon Ash (Fraxinus latifolia) Forests of the Willamette Valley, Oregon

Creator:: Prive, Sean
Abstract:: As species of ash trees become increasingly threatened worldwide by exotic pests and pathogens, it is important to develop descriptions of their ecologies that help guide the conservation and restoration of forests in which they are a major component. Oregon ash (Fraxinus latifolia) is a dominant tree species in wetland...

The Effects of Road Noise on Pacific Chorus Frog Communication

Creator:: Nelson, Danielle V.
Abstract:: Amphibians are experiencing global population declines and are one of the most threatened groups of vertebrates. This can be attributed to multiple environmental stressors such as habitat loss, disease, invasive species, and climate change. For vocal amphibian species, loss of acoustic habitat due to anthropogenic noise may be yet another...

Mulching to Manage Mummy Berry of Blueberry

Creator:: Florence, Jade
Abstract:: Monilinia vaccinii-corymbosi pseudosclerotia overwinter on the soil surface and produce apothecia in early spring, providing primary inoculum for Mummy Berry Disease of blueberry. Burial under 2.5 cm of soil or the absence of light have previously been identified as critical factors preventing the development of apothecia. Mulches were applied to...
