The sweet potato is one of the world’s most widely consumed crops, yet its evolutionary history is poorly understood. In this paper, we present a comprehensive phylogenetic study of all species closely related to the sweet potato and address several questions pertaining to the sweet potato that remained unanswered. Our...
The desire to apply short-range wireless communication systems to telemetry sensor networks in a metal-enclosed chamber has prompted this study. This thesis will discuss the design of an infrared (IR) communication system for a wireless low-power, low-data- rate sensor network in a metal enclosure. This design requires an in-depth understanding...
This dissertation constitutes a multi-scale quantitative and qualitative investigation of patterns of urban development in metropolitan regions of the United States. This work has generated a comprehensive data set on spatial patterns of metropolitan development in the U.S. and an approach to the study of such patterns that can be...
In 2008, the Department of Land Conservation and Development (DLCD) asked the Institute for Natural Resources (INR) to assess whether the Oregon Land Use Program, as designed, is helping the state meet its land use goals. More specifically, this intensive but highly time-limited research effort set out to answer the...
Many Gram-negative bacteria use a type III secretion system (TTSS) to establish a relationship with a host. Pathogens can use the secretion system as a way to deliver proteins known as type III effectors (TTEs) into a host cell and block host defense. The variation and redundancy of the type...

SUMMARY
Microorganisms in seagrass sediments facilitate many key ecosystem processes, yet current knowledge of microbial facilitation of seagrass community recovery following disturbance or restoration is limited. We studied microbial community responses to restoration of a subtropical seagrass meadow disturbed by vessel groundings in south Florida, USA, and relationships between microbial communities...
Oregon Department of Environmental Quality (DEQ) permits for discharging seafood-processing wastes into adjacent estuarine waters expire July 31, 1974. Beyond this date, Oregon's seafood processors must adopt one or a combination of three options: curtailment of waste production, disposal outside of estuaries, or conversion of waste to some other product....
