A monitoring system for identifying and recording land conversion in agricultural lands with SCS Soil Capability Classes I-IV

Creator:: Parker, Douglas Stuart
Abstract:: This paper discusses the structure, rationale, and application of a monitoring system specifically designed to identify and record conversion of lands with Soil Conservation Service Soil Capability Classes I-IV. Research methodology and design are structured to objectively assess the rates of agricultural land conversion to non-farm uses over a given...

Independent Volunteer Travelers in Nepal

Creator:: Douglas, Heather F.
Abstract:: The objective of this research is to shed light on the phenomenon of independent volunteer traveling. It represents a form of tourism in which travelers independently organize their own volunteer efforts and typically provide assistance to local people in return for room and board. Travelers operate outside the confines of...

Soil compaction in central Oregon volcanic ash soils and the subsequent effects on residual ponderosa pine growth

Creator:: Parker, Robert T.
Abstract:: Although previous research in central Oregon has shown soil compaction can lead to a decline in site productivity, the subject is not understood well enough to predict the growth changes resulting from a given level of soil compaction. A study was initiated to relate the basal area, height and volume...

Spatial and Temporal Patterns of Detection of Native Lampreys in Central Valley California: A Starting Point

Creator:: Parker, Christina M.
Abstract:: Native lamprey species in the Central Valley of California serve important ecological roles in rivers and tributaries and face similar conservation challenges as salmonids. Concerns of declining lamprey populations have led to collaboration of tribes, local, state, and federal agencies to increase understanding of ecology and life history. Pacific Lamprey...

Climate Change Impacts to Estuarine Hydrodynamics: Tools, Methodologies, and Predictions

Creator:: Parker, Kai A.
Abstract:: Coastal communities in the U.S. Pacific Northwest (PNW) are rapidly engaging with the idea that hazards and environmental pressures are changing and may be characteristically different in the near future. This has led to a need for scientific knowledge and tools that can help coastal communities prepare and build resilience...

Activation, modification and suppression of sex pheromone production in garter snakes

Creator:: Parker, M. Rockwell
Abstract:: Vertebrates communicate with one another and coordinate intraspecific reproduction by using a variety of sexually dimorphic signals, such as plumage, ornaments, sounds, and/or scents. These sexual dimorphisms are maintained by physiological factors, typically sex-specific hormones (though see Chapter 3 for an exception). The purpose of the research in this dissertation...

The Social Interactions of Pseudomonas aeruginosa

Creator:: Smith, Parker
Abstract:: Pseudomonas aeruginosa is a ubiquitous environmental microbe, opportunistic pathogen, and a highly social organism. P. aeruginosa utilizes a wide array of cooperative behaviors to adapt to the environmental conditions around it. These behaviors include quorum sensing (QS), a form a cell-to-cell signaling that coordinates the expression of secreted products in...

Hydrophobicity, Anion Exchange, and Phytoaccumulation of Per- and Polyfluoroalkyl Substances (PFAS): Retention and Remediation

Creator:: Parker, Bethany A.
Abstract:: Per- and polyfluoroalkyl substances (PFAS) are a group of contaminants of great concern due to their toxicity and ubiquity in the environment. Remediation efforts historically have focused on granular activated carbon (GAC) because of its low maintenance and relatively low cost. However, GAC is not PFAS selective and is especially...

Intravenous regional limb perfusion with tiludronate in horses

Creator:: Hunter, Barbara, G.
Abstract:: Intravenous regional limb perfusion (IVRLP) with tiludronate is a commonly used treatment for distal limb orthopedic disease in horses, but doses and protocols are anecdotal. IVRLP exposes articular cartilage within the perfused area to tiludronate, raising concerns about safety of this treatment, as high tiludronate concentrations (≥19mg/L) were harmful for...

Inter-relationships of vegetation, hydrology and micro-climate in a young, Douglas-fir forest

Creator:: Barnard, Holly Rene
Abstract:: The links between forests, streamflow, and climate are poorly understood. Despite hundreds of studies over the past 60 years, fundamental questions of forests' effects on the hydrologic cycle remain unanswered. The hydrological cycle involves mutually-dependent biological and physical processes that operate at multiple scales of time and space, and this...
