Vegetation ecology and net primary productivity of selected freshwater wetlands in Oregon

Creator:: Boss, Theodore R. (Theodore Robert)
Abstract:: Vegetation ecology of eight Oregon freshwater wetlands was described and net aerial primary productivity estimated in four wetlands. Plant cover samples were used to classify 37 wetland and 11 terrestrial communities by agglomerative hierarchical clustering. Samples and species were ordinated. Direct measurements were made of sample relative elevation, inundation duration,...

Incorporation of diet information derived from Bayesian stable isotope mixing models into mass-balanced marine ecosystem models : a case study from the Marennes-Oléron Estuary, France

Creator:: Pacella, Stephen Roger
Abstract:: This thesis presents two related studies on the methodology for creating, and subsequently analyzing, an inverse food web model of an intertidal seagrass bed. The first study (Chapter 2) describes, for the first time in the literature, a method for incorporating isotopic information gained from Bayesian mixing models into an...

Geographic variations in water quality and recreational use along the upper Wallowa River and selected tributaries

Creator:: McDowell, Theodore R.
Abstract:: Physical, chemical and bacterial water quality parameters of the upper Wallowa River were sampled periodically between July 2, 1978 and June 9, 1979 at nine stream and lake sampling sites. Water upstream from Wallowa Lake was typified by low nutrient concentrations ( generally below detectable limits except for nitrates), low....

Applying economic benefit transfer to improve the transfer of ecological estimates in ecosystem services research & policy

Creator:: Errend, Melissa N.
Abstract:: The goal of this thesis is to advance the methodology and thought regarding the transferability of ecological estimates of ecosystem services. Conceptually and in practice, ecological estimate transfer parallels economic benefit transfer in ecosystem services research and policy, yet the literature for benefit transfer predates ecological estimate transfer by several...

The spectral backscattering properties of marine particles

Creator:: Whitmire, Amanda L.
Abstract:: The inherent and apparent optical properties of different ocean regimes are the basis for all optical remote sensing of the ocean. Ecological information derived from remote sensors therefore relies on having a detailed understanding of how particulate backscattering and absorption contribute to the bulk optical signal. The absorption characteristics of...

The influence of bottom morphology on reflectance : theory and two-dimensional geometry model

Creator:: Zaneveld, J. Ronald and Boss, Emmanuel
Abstract:: The reflectance of the bottom is of importance when interpreting optical data in shallow water. Closure studies of radiative transfer, interpretation of laser line scanner data, lidar, and remote sensing in shallow waters require understanding of the bottom reflectance. In the Coastal Benthic Optical Properties experiment (CoBOP), extensive measurements of...

Using demographic and clinical variables to predict the length of stay of "incompetent to stand trial" patients

Creator:: Ficken, Carl Theodore
Abstract:: In Oregon, "Incompetent to Stand Trial (1ST) Patients" were observed to be increasing in number, remaining in the hospital longer, and costing more to treat. A study was designed to investigate variables that could be used to predict their length of stay at Oregon State Hospital. Data for thirteen independent...

Deep ultraviolet solid-state laser development

Creator:: Dutton, David A. (David Adam)
Abstract:: There is a new possibility of generating deep ultraviolet laser radiation from a solid-state source. With recent advances in material development, a new nonlinear optical crystal provides a greater damage threshold than current materials making higher conversion efficiencies possible. This thesis examines the possibility of using this crystal to generate...

An overview of natural gas well pad surface disturbances and techniques used to increase reclamation success within the Vermillion Basin, Wyoming

Creator:: Inman, Theodore
Abstract:: The Vermillion Basin, located in southwest Wyoming is an inhospitable, high altitude desert with unique biota and environmental conditions. The area has a long history of usages by humans including recreation, livestock grazing and mineral development. The natural gas industry has had a strong presence in the area since the...

The phytotoxic effects of herbicide and adjuvant application by physiological timing on the woody shrub salal (Gaultheria shallon)

Creator:: Downs, Theodore
Abstract:: Salal is plant species that is native to forestland throughout the PNW and northern California that has been identified as a competitor to early crop tree development. This study consisted of a field and a radioisotope laboratory study to test four commonly used herbicides on salal (imazapyr, triclopyr, glyphosate, and...
