Organismal tolerance to abiotic environmental stresses contributes significantly to setting the distribution limits of organisms, as demonstrated by vertical zonation patterns in the marine intertidal zone. In this thesis, the ultimate (evolutionary) and proximate (mechanistic) causes of tolerance to temperature and emersion stresses associated with the intertidal zone were examined...
The role of viral proteins in the pathogenesis of infectious hematopoietic necrosis
virus (IHNV) was studied at the molecular level. The expression of the viral genes at the
protein and RNA level, and their cellular localization, were characterized to further our
understanding of viral pathogenesis. The pathogenic effect of individual...
This is an investigative, descriptive study that explored fishing regulation conflicts between commercial fishermen and fishery resource management agencies. The purpose of the study was to develop a rich picture of the conflict phenomenon and apply sociological theory in order to illuminate the underlying structures and functions which contribute to...

Gradients of physical disturbance are central to
theories of community organization yet rarely are studies
performed in which physical factors are experimentally
manipulated. Pothole tidepool algal communities exhibit
distinct zonation patterns from top to bottom that result
from scouring by rocks and other debris in the pools.
Scouring is easily...
Today's office worker is being expected to operate computers in order to
increase office productivity. While learning the new technology is a positive
challenge for most people, some students experience a negative computer
attitude when faced with computer training. This study sought to determine if
there were significant differences about...
The immune systems of various teleost fish have been studied in some detail for
the past several decades. One aspect of fish immunity, that of endogenously produced
modulating factors, has recently received a great deal of attention. Understanding the
functions and roles of endogenous factors that regulate fish immunity is...
Currently little is known about the mechanisms and locations of
lymphocyte development in teleosts. In this study several aspects of the
underlying factors which govern B lymphocyte development in trout
were investigated which included: the isolation and characterization of
immunoglobulin heavy chain (IgH) genes, the recombination activating
genes 1 and...
Between 1880 and 1900, the Oregon Women's Christian Temperance Union (WCTU) significantly impacted the lives of Oregon women. Not simply an organization of middle class white women, the Oregon WCTU enlisted Native American and African American women, and persistently advocated for improved conditions for working women. The WCTU aspired to...
