The purpose of this study was to determine plant species composition, community structure, successional relationships, vegetational development and plant distributions in estuarine salt marshes on the Pacific Coast of Oregon.
Quadrat and transect samples of plant presence and cover, collected from April 1971 - June 1974, were subjected to phytosociological...
Reinterpretation of the leafhopper tribe Scaphytopiini reveals it
to be primarily a New World taxon with only limited representation in
the Palearctic, Oriental and possibly Ethiopian regions. Approximately
75 species assigned to three genera are known from the United
States and Canada with at least another 75 species representing an...
Erythrocytic inclusion body syndrome (EIBS) was artificially
established in selected stocks of juvenile fall and spring chinook
salmon (Oncorhynchus tshawytscha), chum salmon (0. keta), coho
salmon (0. kisutch), Atlantic salmon (Salmo salar), and rainbow
trout (0. mykiss). Adult spring chinook salmon were also
artificially infected with the EIBS virus. Adult...
Women entrepreneurs are an economic force within the American and Oregon economy. Women are starting businesses at two to five times the rate of men. There has been significant research detailing the demographics, barriers, and business management skills of women business owners. Yet, the research to date has been limited...
I examined the biomechanical factors that influence the sizes of intertidal macroalgae by studying a population of Fucus gardneri at Fogarty Creek Point, OR. I constructed a mathematical model to predict optimal sizes and probabilities of survival for Fucus under conditions of high and low wave exposure. Predicted optimal sizes...
This study was designed to assess the relationship of selected
factors to the developmental outcome of fundamental motor
skill performance in young children ages 3 to 6 years residing
in foster or adoptive care, and have a documented history of
prenatal exposure to cocaine and other drugs. Using an

Academic advising on American college and university campuses
has evolved into a professional activity supported by a growing body
of theory and research. Developmental psychology provided the
foundation for an approach to advising that emphasizes an holistic view
of the student by supplementing traditional advising functions with
career and personal...
Index selection provides an efficient means of conducting selection on multiple traits by combining information on economic value,
heritability, and the genetic and phenotypic correlations between traits to improve overall merit. The use of this method in forestry has been hampered by the lack of knowledge of the relative importance...
Suspected thifensulfuron resistant spiny annual sow-thistle was identified near Colfax, Washington, in two fields with a winter wheat and lentil rotation. Therefore, studies were conducted to examine resistance of spiny annual sow-thistle to thifensulfuron and cross-resistance to other acetolactate synthase inhibitors and to determine the physiological and molecular basis for...
