Development of a Bioluminescent Sensor of Isothiocyanates through Genetic Modification of Pseudomonas fluorescens and Validation on Crude Plant Materials

Creator:: Hogaboam, Octavia L.
Abstract:: Isothiocyanates (ITCs) are produced by roots in a variety of agricultural plants, such as those within the Brassicaceae family. ITCs act as fumigants, and are used to control microbial plant pathogens by adding brassica-origin seed meal to soil prior to replanting. However, there is suggestion that the presence of residual...

The Fitness Costs and Regulatory Strategies of Cooperative Siderophore Production in Pseudomonas

Creator:: Sexton, David
Abstract:: Cooperative behaviors in bacteria are increasingly appreciated for their relevance to microbial ecology and utility as model systems for social evolution. One example is the secretion of siderophores, a structurally diverse group of compounds that chelate extracellular iron. Siderophore production is considered cooperative because the benefits can be shared with...

Long-Term Soil Productivity in Christmas Tree Farms of Oregon and Washington: A Comparative Analysis between First- and Multi-Rotation Plantations

Creator:: Hatten, Jeff, Landgren, Chal, and Hart, John
Abstract:: Christmas tree production removes organic matter and associated nutrients from a site and can change soil physical properties, reduce mycorrhizal populations, and result in pesticide over-use/accumulation. These impacts have been implicated in potential field productivity declines. Assessing Christmas tree productivity is complicated by genetics, management, and market forces. We approached...

Runoff and Sediment Transport from Harvested Hillslopes to Riparian Buffers of Rocky Mountain Headwater Catchment

Creator:: Puntenney-Desmond, Kira C.
Abstract:: Shallow subsurface flow and surface runoff are spatially and temporally variable in forested environments. The location and timing of this runoff depends on both site characteristics (e.g., vegetation, soil texture, geology, and topography) and on time-varying conditions (e.g., soil water content, precipitation type, duration, magnitude, and intensity). Forest management activities...

Estimation of Soil Particle Size Distribution using CT Scans

Creator:: Boath, Max E.
Abstract:: Remote sensing techniques have been applied extensively in geospatial investigations, but their use in measuring soil physical attributes has been far less explored. Soil particle size distributions (PSD) are indispensable in modeling pedological and hydrological processes as well as biodiversity. However, estimation of PSD via gravimetric measurement methods, the standard...
