Field investigations were implemented to study the interrelationships between streamflows and salmonid production during the summer-fall low flow period in two natural stream channels. Elk Creek, near Cannon Beach in Clatsop County, was the site selected for intensive investigation.
Construction of streamflow control and diversion facilities was completed in November...
This report presents data collected during the first full field season of
a project designed to examine the streamflow requirements of juvenile salmonids. Problems encountered in the original design, changes made in the design and the application of the expected results are discussed.
One assisted reproductive tool used to propagate highly desirable genetics from elite sire and dam matings is embryo transfer. Superovulation is the first part of the overall protocol and it is a required yet costly and biologically stressful procedure in cattle embryo transfer. The process of superovulation results in high...
OmniGen-AF® (OG; Prince Agri Products, Inc., Quincy, IL) is a feed additive containing brewers dehydrated yeast and B-vitamins that supports immune function in ruminant livestock. Targeted profiling of immune-associated genes in whole blood is an effective platform for identification of a) novel molecular pathways and b) immune response markers to...

Today's consumers have shown a greater concern in the relationship between dietary fat and human health. The demand for leaner meat is continuously on the rise. The reduction of fat deposits in the abdominal area of ready-to-cook fryers, considered a waste product in the poultry industry, has become a major...
The International Commission on Radiological Protection (ICRP) has modeled twelve reference animal and plant (RAP) species using simple geometric shapes in Monte–Carlo (MCNP) based simulations. The focus has now shifted to creating voxel phantoms of each RAP to advance the understanding of radiation interactions in nonhuman biota. The work contained...
The International Commission on Radiological Protection (ICRP) has modeled twelve reference animals and plants (RAPs) with simple geometric shapes to be used when estimating radiation dose to non-human biota (NHB). In recent years, there has been interest in creating more realistic models in order to better understand the radiation interactions...
This thesis uses a hedonic price model to estimate the value of water for irrigation in Deschutes County, Oregon. The analysis uses a dataset comprising information on 2,274 agricultural parcels across the County. Uniquely, the analysis successfully utilizes assessor-determined real market values in the place of actual land sales. A...
Project AFS 31 Final report The final report of a study to determine whether discrete races of summer steelhead races exist in the Rogue River, and if so to isolate each race in terms of life history and ecological behavior, including such points as time of entry, seasonal positioning and...
A critical study of the cold vapor atomic absorption and fluorescence instrumentation for the analysis of mercury is described. Some of the important modifications involve the reduction vessel, absorption cell, fluorescence cell, and radiation source. The new modified systems have much greater calibration sensitivities and lower detection limits than those...
An automated multielement flame atomic fluorescence (AF) spectrometer based on microcomputer control was constructed to determine four elements simultaneously. The instrument employs a multiple exit slit monochromator where the light from various exit slits is directed to a single detector with a mirrored funnel. Each element is excited to fluoresce...
Grassy balds are meadows that occur on or near the summits of montane peaks and ridges. The sites on which balds are located generally fall within the climatic tolerance ranges of associated tree species. This study evaluates the stability of a forest-meadow transition zone of such a bald on Marys...
The problem of extinction in the sea has been recognized
only recently by the scientific community (Roberts and
Hawkins 1999). For the last decade, the American Fisheries
Society (AFS) has pursued an initiative to identify marine
fish stocks that may be at risk of extinction in North America
(Musick 1998;...
To evaluate the immunologic and metabolic effects of OmniGen-AF® (Phibro Animal Health corporation, Quincy, IL; OG) supplementation in growing beef cattle, we designed three studies using replacement beef heifers (8.5 and 10.5 months of age) and steers supplemented across backgrounding, transition, and finishing periods. In Study 1, the effect of...
