Biological studies on Saldula palustris (Douglas) with emphasis on factors influencing wing pigmentation (Heteroptera:Saldidae)

Creator:: Stock, Mary Wilford
Abstract:: The life history and wing pattern variation of the intertidal shore bug, Saldula palustris (Douglas), were studied in field and experimental populations from June 1970 until February 1972. The study site was an estuarine salt marsh on Yaquina Bay near Toledo, Oregon. The insects live below mean high water level...

Feasibility of supplementary sampling of the commercial groundfish landings in Oregon using seafood plant workers

Creator:: Builder, Tonya L.
Abstract:: Fishery dependent data--length distributions, sex ratios, maturity schedules, and species composition of landed catches--are necessary for stock assessments. These data are currently collected by state port biologists using a sampling design that randomly selects samples from a small percentage of a very large target population. Sampling programs may need to...

Evaluating the data-poor fishery stock assessment method, DB-SRA

Creator:: Owashi, Brandon R.
Abstract:: Depletion-Based Stock Reduction Analysis (DB-SRA; Dick and MacCall, 2011) is a catch-only fisheries stock assessment model that has been developed to estimate an overfishing limit (OFL) in data-poor situations. DB-SRA projects the biomass trajectories of a stock by means of a catch time series and five parameters: the instantaneous, per...

Sensitivity of the stock synthesis assessment model : a simulation approach

Creator:: Yin, Yanshui
Abstract:: Stock assessments for many U.S. Pacific coast groundfish stocks are developed using the catch-at-age method known as Stock Synthesis. In this work a simulation package was developed and used to evaluate the sensitivity of the Stock Synthesis program. More specifically, the evaluation focused on the impacts of input data errors...

Statistical model selection criteria and their application to the Stock Synthesis assessment program

Creator:: Helu, Siosaia Langitoto
Abstract:: Statistical modeling has evolved around building increasingly more complex models, even though it is common knowledge among statisticians that an optimal model size usually exists for any given data set. Having overly complex models leads to imprecise parameter estimates and tends to increase the subjective role of the modeler, which...

David Foster Wallace's communal middle ground

Creator:: Randlemon, Daniel E.
Abstract:: Throughout the course of this thesis, I argue that the prose of David Foster Wallace, specifically his posthumously published novel The Pale King, inhabits a middle ground between universal sincerity and the particularized authenticity of postmodern irony. I examine Lionel Trilling's definitions of sincerity and authenticity before moving toward an...

Vitamin E effects on sterility of White Leghorn males following prolonged vitamin E deficiency

Creator:: Friedrichsen, Janet Valerie
Abstract:: One group of four adult White Leghorn male chickens was fed a diet containing 7.3% linoleic acid and 32.4 mg/ kg of added vitamin E (group IV) for 50 weeks which was designated as the positive control. A second lot (group I) containing 14 males received the same level of...

Low Maintenance Strategies and Challenges within Oregon School Landscapes

Creator:: Gould, Micah A.
Abstract:: Ornamental landscapes require considerable amounts of inputs, including but not limited to irrigation, mowing or pruning, fertilization, and pest management. However, school systems have limited budgets, which reduce their access to resources and labor hours. Therefore, the objective of this project is to identify ground covers that can compete with...

Stock Synthesis Assessments of Spatially Structured Fish Populations with an Environmental Driver on Recruitment Distribution : A Simulation Study and Discussion

Creator:: Denson, LaTreese S.
Abstract:: Stock assessments use statistical models and empirical data to re-create the population dynamics of a stock in order to provide estimates of biomass and fishing mortality rates to inform fisheries management. Fish stocks are not uniformly distributed across spatial regions, but stock assessments typically ignore stock spatial structure, for the...
