In November 1990, Oregon voters approved Ballot Measure 5,
placing an ultimate ceiling on local property tax rates of 1.5% of
market value (excluding specific levies for capital expenditure). Any
resulting shortfalls in local education revenues are to be made up by
transfers from state funds, at the expense of...
A study is conducted to provide information useful to the future development of agro-pastoralists
in the Kolda Region through an economic and socio-cultural analysis of the
practice of stabling. Two main issues are addressed: the generation and distribution of
profits and the factors related to adoption of stabling. A partial...

The federal government is the largest single landowner in the 11 western states. The majority of federal lands is grazed by domestic livestock, a consumptive resource use. Communities have evolved dependent on traditional consumptive uses. Recently, non-traditional users today have contested public land management decisions and these users have become...
The conservation of open space will become increasingly important as populations expand and undeveloped land is converted to urban uses. The benefits derived from open space conservation include protecting and improving water quality, providing wildlife habitat, maintaining scenic amenities and rural character, and supplying certain recreational opportunities. This study utilizes...

A method has been developed for the continuous automated monitoring
of cardiac output in adult rainbow trout. Average cardiac output measured under
control conditions and varied environmental conditions of hypoxia and post-hypoxia
was significantly higher (P≤ 0.05) in male than female trout. The cardiac
output of trout in spawning condition...
The pesticide carbaryl is applied annually to tidelands in Willapa Bay and Grays
Harbor, WA to control populations of burrowing shrimp which modify sediments making
the habitat unsuitable for oyster culture. Fish trapped on sprayed mudflats are often killed,
but little is known about effects on fish present in subtidal...
The "equilibrium partitioning theory" is one of the most widely used models to evaluate the
bioavailability of sediment-associated, nonpolar, organic contaminants and it makes
specific assumptions regarding the factors that influence this bioavailability. The objective
of this research was to test two assumptions of this theory: (1) that benthic organisms...

The ecology of netleaf hackberry (Celtis reticulata Torr.) is poorly known
throughout its broad western range. To gain some understanding of the species' basic
ecology, three components of its life history were studied. First, seed germination
requirements were analyzed under laboratory conditions. Second, hackberry population
dynamics were evaluated from tree...
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...
The relationship between nutrients and community structure is poorly understood in open-coast habitats. I created a system of artificial tidepools, of identical age and physical dimensions, at two sites that differed in wave exposure, and manipulated nutrient levels and the abundance of herbivores. Using these unique field mesocosms, I explored...
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...
The influence of large-scale processes on natural communities has become one of the central issues of modern ecology. I combined field and laboratory studies to investigate the effects of variation in coastal upwelling on rocky intertidal communities along the central Oregon coast. I examined whether the growth of intertidal barnacles...
Staphylococcal tenosynovitis and osteomyelitis are world-wide problems of
broilers and broiler breeders caused by staphylococci. Pathogenesis of the disease is
ill defined. Avian heterophils are analogous to mammalian neutrophils but the

The first chemotactic study was done on heterophils from chickens having
natural staphylococcal infection...
Coastal communities in Oregon have experienced dramatic economic and demographic change during the 1980s. Although the timber and fishing sectors are still important, the economies of coastal communities now rely more on non-earned income and tourism. Non-earned income sources, such as transfer payments and investment earnings, account for over forty...
This study examined the utilization of selected student services by domestic and
foreign students in their sophomore, junior, or senior year at Oregon State University during
Winter 1994 to find out if differences in awareness, usage, and satisfaction existed between

On Oregon coastal rocky shores, filter‐feeders were relatively abundant and macrophytes were relatively scarce at Strawberry Hill, whereas opposite abundance patterns occurred at Boiler Bay. To determine whether nearshore oceanographic differences were associated with these patterns, we made shore‐based measurements of nutrient and Chl a concentrations. We used a three‐level...
Vaccinia virus encodes at least eight proteins that are modified post-translationally by the addition of a 16-carbon saturated fatty acid through thioester linkage to cysteine residues. This is referred to as palmitylation of proteins. The purpose of this work was to gain an understanding of palmitylation, focusing on what defined...
Building institutional and human capacity for integrated coastal zone management (ICZM) is

Ribosomes are multicomponent macromolecular particles and
are essential for the survival of cells in all organisms. The ribosome's
universal function is to catalyze polypeptide synthesis through
translation of mRNA transcripts. Ribosomes from Escherichia coli,
eubacterial organisms, have a sedimentation coefficient of 70S and are
composed of 30S and 50S ribonucleoprotein...
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...
This thesis reports on research conducted to determine

The education (particularly graduate education) of Americans
who were active in astronomical research between 1876 and 1941

Accurate taxonomy is essential to preservation and management of native
grasses. Four problems in fescue taxonomy were investigated: the identity of the
native fescue that dominates western Oregon and Washington prairies, the relationship
of native Festuca roemeri to closely related grasses, the status of F. howellii and F.
washingtonica, and...
