Simulating extreme total water levels using a time-dependent, extreme value approach

Creator:: Serafin, Katherine A.
Abstract:: Coastal flood hazard zones and the design of coastal defenses are often devised using either the maximum recorded total water level (TWL) or a 'design' event such as the 100-year return-level flood, usually projected from observed extreme events. Despite technological advances driving more consistent instrumental records of wave heights and...

Effect of dietary crude protein level and source of supplemental protein on performance of commercial rabbits

Creator:: Sanchez, William K.
Abstract:: A study was conducted to determine the effect of dietary protein on performance of commercial New Zealand White rabbits. In Part I of this study, three levels of crude protein (17.5, 19 and 20.5%) were fed to lactating does and their offspring during a 12 month period. Total rabbits born...

Episodic dynamics of microbial communities associated with the birth and death of ectomycorrhizal mats in old-growth Douglas-fir stands

Creator:: Blanchard, Joseph H.
Abstract:: Ectomycorrhizal (ECM) fungi of the genera Piloderma and Ramaria form dense hyphal mats in the organic and upper mineral soil layers, respectively, in coniferous forest floors of the Pacific Northwest. Previous studies have determined that fungal mats change the chemical, physical, and biological properties of the soil within. Little information...

Symbiotic and saprophytic characteristics of a soil population of Rhizobium leguminosarum bv. trifolii

Creator:: Yap, Kathryn H. M.
Abstract:: Although much has been learned about the comparative nodulating behavior of simple mixtures of rhizobial strains under non-soil situations, it is unclear how these findings relate to the factors influencing nodulation success by the complex mixtures of strains found within soil-borne rhizobial populations. Information on the structure and physiological behavior...

Adequacy of hand-defoliation of tansy ragwort (Senecio jacobaea L.) as a simulation of defoliation by cinnabar moth (Tyria jacobaeae (L.))

Creator:: Henneberger, Diane
Abstract:: Hand-defoliation was evaluated for its ability to simulate herbivory by cinnabar moth larvae, Tyria jacobaeae (L.) (Arctiidae) on the weed tansy ragwort, Senecio jacobaea L. (Asteraceae). The evaluation was done on a field population of flowering ragwort, for three different timings (early, middle, and late season) of damage. In the...

Nearshore wave predictions along the Oregon and southwest Washington coast

Creator:: García-Medina, Gabriel
Abstract:: This thesis contains a manuscript describing the implementation of a high resolution wave forecasting model for the coasts of Washington and Oregon. The purpose of this project was to advance the wave predictive capabilities of the states of Oregon and the southwest part of Washington by including the effects of...

Effects of dietary pyrrolizidine alkaloids on copper and vitamin A metabolism in the chicken and Japanese quail

Creator:: Huan, Jianya
Abstract:: Objectives of this study were to examine effects of dietary pyrrolizidine alkaloids (PA) on copper and vitamin A metabolism in the chicken which are very susceptible to the hepatoxic effects of PA and Japanese quail which are highly resistant to PA. Also, the possible interaction between copper and vitamin A...

Monitoring pesticide resistance in Psylla pyricola Foerster from western Oregon pear orchards

Creator:: Follett, Peter A.
Abstract:: A modified slide-dip bioassay was used to survey and establish baseline resistance levels in Psylla pyricola Foerster from western Oregon orchards to four pesticides. Orchards selected in the Hood River, Rogue River and Willamette Valleys spanned a wide range of environmental and management conditions. During the study period of 1982-1983,...

The effects of kernel feeding by brown marmorated stink bug (Halyomorpha halys: Hemiptera: Pentatomidae) on commercial hazelnuts (Corylus avellana L.)

Creator:: Hedstrom, Christopher S.
Abstract:: Halyomorpha halys (brown marmorated stink bug, Hemiptera: Pentatomidae), an invasive insect pest, has established populations in the Willamette Valley of Oregon. Halyomorpha halys is a potential pest of many specialty crops in the Willamette Valley, including hazelnuts (Corylus avellana L.). The objectives of this study were to 1) characterize the...
