Integration of submersible transect data andhigh-resolution sonar imagery for a habitat-based groundfish assessment of Heceta Bank, Oregon

Creator:: Nasby, Nicole M.
Abstract:: Dramatic declines in several groundfish populations have occurred along the U.S. West Coast during the last decade (PFMC 1999, Sampson 1997, Ralston 1998, Bloeser 1999). One problem exacerbating these declines is insufficient stock assessments, especially for species of west coast rockfish (Family Scorpaenidae, Genus Sebastes) which comprise the core of...

The effect of varying levels of readily available carbohydrates on urea utilization

Creator:: Wright, Rodney Joseph
Abstract:: The object of this research was to study the effect of readily available carbohydrates (RAC) upon the utilization of urea in fattening rations and to determine the effect upon carcass characteristics that determine quality and yield grades. A 2 x 2 latin square designed feedlot trial comparing urea at 0.5%...

Uncertainty in neutron probe measurements of soil moisture for irrigation scheduling

Creator:: Wright, Norman D.
Abstract:: Soil moisture in a crop's root zone must be regularly monitored to accurately predict crop water requirements. Most irrigation scheduling services currently use the neutron probe to monitor soil moisture. Unfortunately, there is a degree of variability associated with use of the neutron probe creating uncertainty in measurements of soil...

The marine geomorphology of American Samoa : shapes and distributions of deep sea volcanics

Creator:: Roberts, Jed T.
Abstract:: The geologic processes at work in American Samoa have long been a point of scientific debate. Of its numerous volcanic formations, few breach sea level, leaving an enormous proportion of their mass unavailable to traditional observation. This study aims to describe the deep sea geomorphology of American Samoa through compilation,...

Derivation of near-shore bathymetry from multispectral satellite imagery used in a coastal terrain model for the topographic analysis of human influence on coral reefs

Creator:: Hogrefe, Kyle Richard
Abstract:: The analysis of material and energy exchange between the marine and terrestrial components of island ecosystems enables research into the impact of human population and land use on the health of coral reef habitat. Satellite and acoustic remote sensing technologies enable the collection of data to produce high resolution bathymetry...

Risk Assessment of Salmonella in Raw Hazelnuts and use of Propylene Oxide as a Potential Mitigation Strategy

Creator:: Wright, Daniel G.
Abstract:: Multiple outbreaks of foodborne illness (Salmonella and E. coli O157:H7) have been associated with tree nuts and tree nut products since the early 2000s. In response to these outbreaks and many others in fresh produce and peanut butter, Congress created and passed the Food Safety Modernization Act (FSMA) to require...

A systematic and ecological study of Astragalus diaphanus (Fabaceae)

Creator:: Wright, Carolyn E.
Abstract:: Astragalus diaphanus is a rare plant endemic to the John Day River drainage of north-central Oregon. This species has several interesting features, including the dimorphism of its fruit and its geographical isolation from the two nearest taxonomically related species, which occur in Colorado. This study addressed the species' distribution and...

Effects of Forest Harvest, Floods, and Wildfire on Bedload Export from Headwater Catchments in the H.J. Andrews Experimental Forest, 1957 – 2022

Creator:: Wright, Charles M.
Abstract:: This study examined how annual bedload export volume and bedload characteristics were related to disturbances including logging, floods, debris slides, and wildfires over 48 to 65-year periods in small, steep catchments in conifer forests of the western Cascade Range, Oregon. Bedload – the material rolling, sliding, or saltating along the...

The Potential of Dynamic Segmentation for Aquatic Ecosystem Management : Pacific Lamprey Decline in the Native Lands of the Confederated Tribes of Siletz Indians (Oregon, USA)

Creator:: Palacios, Kelly C.
Abstract:: The Lamprey Eel Decline project conducted by the Confederated Tribes of Siletz Indians (CTSI) combined traditional ecological knowledge, scientific research and geographic information science. CTSI wanted to learn why the Pacific lamprey (Lampetra tridentata), a culturally and ecologically important species, was declining in the streams within their native land area....
