Impacts of dwarf mistletoe on the physiology of host Tsuga heterophylla trees as recorded in tree ring C and O stable isotopes

Creator:: Marias, Danielle E.
Abstract:: Dwarf mistletoes, obligate, parasitic plants with diminutive aerial shoots, have long-term effects on host tree water relations, hydraulic architecture, and photosynthetic gas exchange and can eventually lead to tree death. To investigate the long-term impacts of dwarf mistletoe on gas exchange of host western hemlock trees, I compared growth, gas...

The Effects of Biofilm on Sandy Soil Hydrology

Creator:: Runion, Danielle N.
Abstract:: It is known that soil biota affects water dynamics through various complex mechanisms. The impact on retention by soil biota are due to a combination of changes to pore geometry, pore clogging by biofilms, biofilms that serve to connect thin water films across many pores as the soil dries, and...

Flow processes in the dry regime : the effect on capillary barrier performance

Creator:: Jansik, Danielle P.
Abstract:: Engineered capillary barriers typically consist of two layers of granular materials designed so that the contrast in sediment hydrologic properties and sloping interface retains infiltrating water in the upper layer. We report here on the results of two bench-top capillary barrier experiments, and associated modeling. These experiments were conducted to...

Understanding the future of PFAS policy and management : a comparative study between two regions – the Pacific Northwest and the Great Lakes Region

Creator:: Tran, Danielle N.
Abstract:: In the past fifty years, per- and polyfluoroalkyl substances (PFASs) have become alarming global pollutants. In 2019, the United States (U.S.) Environmental Protection Agency (EPA) ultimately classified them as emerging contaminants and established an action plan to address PFAS and protect public health through developing, identifying, monitoring, and remediating current...

Sliding Mode Control of Oscillating Water Column Wave Energy Converters

Creator:: Brown, Danielle R.
Abstract:: This thesis concerns the development of a direct torque control strategy using a sliding mode control approach to optimize the power output of an oscillating water column (OWC) wave energy converter (WEC). The OWC WEC is a device that has a submerged vertical tail tube open at both ends, which...

Molecular and rheological characterization of sodium hyaluronate (HA) and equine synovial fluid

Creator:: Leiske, Danielle Lurisa
Abstract:: Sodium hyaluronate (HA) is a polysaccharide found in all parts of the body Although it performs important functions in the eye, the coagulation process and other parts of the body, its contribution to synovial fluid is particularly important. As the major component of synovial fluid, HA is responsible for the...

Critical incident response on a small college campus

Creator:: Marlette, Danielle M.
Abstract:: Campus administrators are partially responsible for how a campus responds to a critical incident and how the students and outside community are impacted. It is important for administrators responding to critical incidents to take an objective look at their plans and preparations to determine if they will truly be effective...

Developing a Drought Metric with Water Managers

Creator:: Moruzzi, Danielle L.
Abstract:: Though numerous drought metrics have been developed by the research community, adoption of these metrics by water managers has been limited. The reasons for this vary, but some include mismatches in time scales and spatial scales between the metric supplied and the operational decisions (e.g. water managers often work within...

What's that on the beach? Designing a Protocol for the Identification and Reporting of Stranded Marine Fish, Squid, and Turtles Using the Oregon Coast as a Proof-of-Concept

Creator:: Asson, Danielle and Asson, Danielle C.
Abstract:: It is not unusual to see stranded or washed-up marine animals and birds along any coastline. Various networks nationwide exist to report marine mammals and sea birds, yet, we have been unable to find a network in Oregon or nationally to report other stranded marine animals, namely fish, cephalopods, and...

Contributions of riparian vegetation and stream morphology to headwater stream temperature patterns in the Oregon Coast Range

Creator:: Smith, Danielle D.
Abstract:: The role of riparian forests in maintaining temperatures of headwater streams is well established and is a foundation of forest practice rules designed to protect streamwater quality. However, detailed investigation is still needed quantifying specific characteristics of stream systems that affect streamwater temperature including riparian features, stream morphology, and subsurface...
