Glochidial development in freshwater mussels (Mararitifera margaritifera) located in the Siletz River, Oregon, was completed in 13 days at an average water temperature of 12.8 C. Glochidia were released by these mussels for 33 days, May 13 to June 15, 1971. The comparative susceptibility of four species of salmonid
fishes,...
The purpose of this study was to ascertain the usefulness of
sensitivity training with wives of graduate students in decreasing

This research was conducted on three study areas on elk winter
ranges in Northeast Oregon. One was on the Starkey Experimental
Forest and Range and the others were in the same vicinity. Plant

Jackson County, Oregon is noted for the production of high quality
pears. It is the fourth leading pear producing county in the United
States and is the number one producer of winter pears. This thesis
analyzes in detail the many aspects of the pear industry in the county.
Climate, soils,...
Relatively recent increases in ponderosa pine abundance have effected unprecedented changes to ecosystem structure and function. Efforts to restore ponderosa pine systems are often focused on the manipulation of tree structure and the re-introduction of a more natural fire regime. Successful restoration should also incorporate understory components but information addressing...
The North Unit irrigation District of Central Oregon,
a water project developed under the guidelines of the
Bureau of Reclamation, is characterized by limited water
and the need for efficient utilization and control of the
irrigation system. To manage the limited water resource,
irrigators need a timely and economical method...
Predetermining the ultimate capacity of piles driven into purely
cohesive soils and purely cohesionless soils involves, respectively,
the consideration of soil shear strength in a completely undrained and
a completely drained condition. For the intermediate cases concerning
soils that possess both cohesion and internal friction (silts, clayey
silts, sandy clays,...
The need to control irreversible conversions of
prime agricultural lands to urban land uses has come to light
in recent years. Resulting policy statements by the State of
Oregon and federal agencies have added support to this
premise. Nevertheless, inefficient conversions of agricultural
to idle lands in response to urban...

People have been growing and enjoying flowers and foliage plants for as long as history has been recorded. Once people’s needs were met for a place to live and food to eat, they began to grow and use plants for their beauty, fragrance, and shade, both indoors and out. Over...
Carbon sequestration is increasingly recognized as an ecosystem service, and forest management has a large potential to alter regional carbon fluxes − notably by way of harvest removals and related impacts on net ecosystem production (NEP). In the Pacific Northwest region of the U.S.,

The purpose of this study was to describe the level to which a target work culture based on core organizational values was shared in one lumber manufacturing plant. The organization under study perceived that their culture was a source of competitive advantage and was key to their success in safety,...
Standard accounts of women's relationship with technology stress women's need to overcome anxiety to achieve competence with computers. Recent studies provide evidence that this woman-anxiety-technology connection is an oversimplification of the relationship between women and computers. New literature also suggests that making computers more appealing will help girls overcome computational...
The resurgence of creationism the past few years has been led by advocates
of recent-creationism. These individuals, a minority among creationists in general,
argue that the entire universe was created approximately 10,000 years ago in one six-day
period of time. Recent-creationists support their position by appealing to the
Genesis account...
With the construction of the Marine Science Center and the opening of its Pacific Fisheries Laboratory in 1965, Oregon State University had facilities for research that would ultimately lead to breakthroughs in Pacific Coast oyster culture. "Purposes of the workshop were to review present and planned programs of research with...
The first study utilized ova transfer in sheep and involved
hormonal treatments for synchronization of estrus and superovulation
in an investigation of crossbred maternal influences on inbred and
linecross lambs.
Synchronization of estrus in ewes was achieved effectively
with either oral progestogen, 6 α-methyl-17α-hydroxy-progesterone
acetate (60 mg./ewe/day), or intramuscular injections...
A model of an exhaust plume was developed and programmed
on a digital computer. The purpose of the model was to predict the
concentration and size distribution of ice particles produced from
automobile exhaust during arctic conditions. The model accounted

The processes responsible for transporting and depositing thick
sections of coarse-grained terrigenous clastics on the abyssal floor
and for forming associated sedimentary structures are still conjectural.
Many workers attribute coarse deep-sea sediments and their
probable lithified equivalent, the graywackes of flysch deposits to
some type of density movement.
Deductions concerning...
Contemporary forest management involves a more extensive and diverse suite of management objectives than was the case throughout much of the Twentieth Century. Heightened public and political awareness of local and global biodiversity decline, and interest in arresting these trends, has increased the emphasis on broad-based biodiversity conservation as an...
The average size and age of chinook salmon (Oncorhynchus
tshawytscha) caught in commercial fisheries along the Pacific Coast
of North America have decreased substantially in this century. These
declines might be caused in part by changes in size and age at
maturity within the stocks contributing to those fisheries. Upriver...

Deep learning has recently revolutionized robot perception in many canonical robotic applications, such as autonomous driving. However, a similar transformation has yet to occur in more harsh environments including underwater and underground. This is due in part to the difficulty in deploying robots in these environments, which lack large real...
Suspended matter in Astoria canyon was monitored by means of an in situ nephelometer and by means of light-scattering and particle concentration measurements performed aboard ship on water samples. Nephelometer profiles obtained along the axis of the canyon in February and April 1973 indicate that the canyon is divided into...
Here we present a phylogeny of beetles (Insecta: Coleoptera) based on DNA sequence data from eight nuclear genes, including six single-copy nuclear protein-coding genes, for 367 species representing 172 of 183 extant families. Our results refine existing knowledge of relationships among major groups of beetles. Strepsiptera was confirmed as sister...
Multiagent approaches are well suited to designing autonomous solutions for systems that feature complex interactions between many individuals such as in autonomous traffic systems and multi-robot exploration systems. However, creating autonomous agents that function effectively in these systems is a challenging task. In these complex environments, agents need informative reward...
Diagnostic carbon cycle models produce estimates of net ecosystem production (NEP, the balance of net primary production
and heterotrophic respiration) by integrating information from (i) satellite-based observations of land surface
vegetation characteristics; (ii) distributed meteorological data; and (iii) eddy covariance flux tower observations of
net ecosystem exchange (NEE) (used in...

Ponderosa pine (Pinus ponderosa) and lodgepole pine (Pinus contorta var. murrayana) forests of south-central Oregon have been extensively researched over the last century. However, little information has been reported on overstory composition and stand structure shifts associated with fire exclusion within inter-mixed ponderosa pine and lodgepole pine stands of the...

Oregon's estuaries are important ecosystems for scientific study. Consequently, knowledge of what research has been conducted helps us identify benchmarks and plan new projects. A comprehensive bibliography of published research, technical reports, local documents, and data sets is one means of recording this knowledge. For these reasons, the Guin Library...

Although public sector unionism dates back at least
to 1916, collective bargaining emerged mid-century when
