The effects of single and multiple pathogen and parasite infections on juvenile chinook and coho salmon during early marine residency

Creator:: Sandell, Todd A.
Abstract:: Nearly 3000 juvenile Chinook (Oncorhynchus tshawytscha) and coho (O. kisutch) salmon captured in nearshore waters off the coasts of Washington and Oregon from 1999-2004 were tested for infection by Renibacterium salmoninarum, Nanophyetus salmincola, and skin metacercariae. First, three quantitative PCR primer/probe sets were compared for detection of R. salmoninarum; amplification...

Using parasite community data and population genetics for assessing Pacific sardine (Sardinops sagax) population structure along the west coast of North America

Creator:: Baldwin, Rebecca E. B.
Abstract:: Pacific sardines (Sardinops sagax) are an economically and ecologically important forage fish which transfer energy from planktonic primary producers and secondary consumers to upper trophic predators. Previous genetics studies of Pacific sardine suggested a panmictic population with a shallow genetic structure. However, more than one subpopulation within the Central California...

Effectiveness of index size reduction techniques

Creator:: Jacobson, Bryan L.
Abstract:: Index size savings from three techniques are measured. The three techniques are: 1) eliminating common, low information words found in a "stop list" (such as: of, the, at, etc.), 2) truncating terms by eliminating word stems (such as: -s, -ed, -ing, etc.), and 3) simple data compression. Savings are measured...

Trophically transmitted parasites as ecosystem indicators : relationships among parasite community structure, juvenile salmon diet composition, and ocean conditions

Creator:: Losee, James P.
Abstract:: Recent research conducted throughout the Northern California Current (NCC) on the ecology of Pacific salmon (Oncorhynchus spp.) indicates that variable ocean conditions affect the community composition of zooplankton in the nearshore environment which, in turn, can affect the quality of prey for fish, sea birds and mammals. Interannual variability in...

A seismic refraction study of the Monterey Deep Sea Fan and a comparison of velocity structures among fan subunits

Creator:: Dwan, Shufa F.
Abstract:: A deep source-receiver seismic refraction experiment was conducted on the upper part of the Monterey Deep Sea Fan. The aim of this thesis is to construct the velocity structure of the upper Monterey Fan and to examine the lateral seismic velocity variations among the upper, middle and lower fan subunits....

Developmental mutants of Phaseolus vulgaris L.

Creator:: Shii, Chou Tou
Abstract:: Hybrids with abnormal development were obtained when particular genotypes of Phaseolus vulgaris L. were crossed. The phenotypic aberrations of the F₁s included retarded growth, chlorosis of the trifoliate leaves and the formation of adventitious roots on the hypocotyls. The expression of the abnormalities was dependent on the temperature. At high...

Relationship between Ascarophis Sp. (Nematoda: Cystidicolidae), Sturgeon Feeding Pit Density and Ghost Shrimp Burrowing Behavior

Creator:: Brockman, Joseph N.
Abstract:: Bioturbation caused by ghost shrimp, Neotrypaea californiensis, burrowing activity can negatively affect Pacific oyster, Crassostrea gigas, aquaculture through their burial and subsequent suffocation. The shellfish aquaculture industry used chemicals to control burrowing shrimp populations in Washington State estuaries for decades, but, due to public and governmental scrutiny, that practice has...

David Hume and the Paradox of Taste

Creator:: Chi, Erik
Abstract:: David Hume’s resolution of the paradox of taste poses an interesting question for us to ponder. Rather than take a purely subjectivist or objectivist view of the topic, Hume strikes a balance between the two positions by upholding two of three statements regarding taste that are widely held to be...
