Geophysical and biogeochemical processes associated with fluid venting from active and passive continental margins will receive significant scientific and economic attention
into the next century and are of major societal relevance. An important unknown among these interrelated processes is the role played by methane gas hydrates, at and below the...
Size and color are important visual quantity attributes of the fruit of strawberry (Fmgaria x ananassa Duch.). Strawberry cultivars produce fruit of a characteristic size and color, the later being the result of accumulation of particular anthocyanins. This research sought to determine the basis for genotypic differences in fruit size...
The Rattlesnake Ash-Flow Tuff erupted 7.05±0.01 Ma from the western Harney Basin, southeastern Oregon. The location of the vent area is inferred based on vent-ward increases in size of pumices, in degree of welding, and in degree of post-emplacement crystallization. Today's outcrops cover 9000 km2 and estimated original outcrop coverage...
The dissertation introduces community-based adaptive watershed management (CAWM) as a holistic conservation framework. The CAWM
framework integrates social and ecological suitability to achieve conservation outcomes. The core theoretical concepts consist of adaptive management, adoption-diffusion,
symbolic interactionism, community-based conservation, spatial analysis and watershed management. The CAWM framework is applied to the...
Past studies of the Oregon and Washington coast have shown a rapid change in the coastal ocean conditions with the onset of upwelling in spring. This process, called the spring transition marks the change from winter to summer conditions along the west coast of Unites States. To examine the interannual...
The purpose of this study was to provide understanding of Oregon Workforce Quality Council contributions to the development of a world-class workforce. Research goals were

This study addresses women's experiences in higher education at Oregon Agricultural College between 1870 and 1916. The experiences of these women illustrate how they were affected by society's beliefs and values, and further, how their education encouraged them to develop skills necessary to transform their role in society. Education has...
Four wetland sites were identified and delineated in Silver Falls State Park, Oregon using procedures outlined in the 1989 Federal Manual for the Identification and Delineation of Jurisdictional Wetlands and subsequently monitored for a ten month period. A network of 225 shallow (32") wells was installed throughout the sites to...
Most recent research on stream amphibians in the Pacific Northwest has focused on associations with reach-level or stand-level environmental features. Little is known about landscape-level distributions of these species or landscape-level aspects of their life-histories. I used a watershed-wide sample and logistic regression to develop models and maps of probability...
With indications that fisheries production has plateued at a global capacity of 85 million metric tons in the 1990's, further exploitation of marine stocks on a sustainable basis is unrealistic. Economic development of coastal and regional economies will benefit from new approaches to maximizing benefits from harvested products that include...
This report and accompanying program inventory have been prepared in support of the Oregon Department of Environmental Quality's statewide nonpoint source pollution control efforts and for use in the development of Oregon's new federally mandated Coastal Nonpoint Pollution Control Program (CNPCP).

An increase in the commercial and recreational harvest of clams in Tillamook Bay, Oregon,
coupled with a general lack of knowledge about the bay's ecology, served as the impetus for a
shellfish survey undertaken in the summer of 1995. Commercial clam harvest has increased
twelve fold since 1978 (Carter et...
Coral reef ecosystems are the oceanic equivalent of tropical rainforests, in terms of biodiversity. The estimated 1,037,000 square kilometers worldwide of reef provide
habitat for over one million species of plants and animals (Hinrichsen, 1997). Coral reefs are important to the economy of coastal nations because of the fisheries and...
Equations for predicting individual-tree height growth per 5-year period are presented for Douglas-fir, white fir, grand fir, ponderosa pine, sugar pine, and incense-cedar growing in the mixed-conifer zone of southwest Oregon. The data used to develop the equations came from 3,648 trees sampled from 391 stands in the study area....
Environmental restrictions have induced many sawmills to seek alternatives to pentachiorophenol (penta) and similar chlorinated phenols for controlling mold and fungal stains on green lumber during storage and shipment. For that purpose, ten alternative stain preventives were evaluated against a traditional penta product (Permatox 101) on studs of Douglas-fir [Pseudotsuga...
Instruction in a University Honors College was evaluated using Small Group Instructional Diagnosis (SGID), a qualitative evaluation process. Fifty-one class sections were evaluated over a three-year period to determine what worked to help students learn, what did not work, and suggestions for improvement. Seven instructors used both SGID and an...
Riparian vegetation (trees > 10 cm dbh), woody debris (> 10 cm diam, > 1 m long), channel, and landform characteristics were inventoried in mature (80-150 yrs) and old-growth riparian areas (>250 yrs) selected from small tributaries of the Coos and Coquille River basins in southwestern Oregon. Basal area of...
This thesis on Rebecca West's writing (1911-1936) addresses the relationship between her polemical essays and her fiction, exploring modernist representations of class and gender differences and conflicts.

Black Brant (Branta bernicla nigricans) had two different seasonal patterns of occurrence at Yaquina Estuary. At embayment areas with eelgrass (Zostera marina), Brant typically arrived between October 22 and November 4, Brant numbers progressively climbed in November, Brant abundance in December-January was relatively constant, and Brant numbers often fluctuated greatly...
Black Brant (Branta bernicla nigricans) distribution was monitored and eelgrass beds (Zostera marina) were mapped during the spring migration of 1976. Brant used eelgrass areas significantly, and human disturbance and tide height were important factors influencing Brant distribution and activity.
Janet Lamberson noted the presence of birds around her home during 1985-1990. She noted 10-33 species each month, 48-57 species each year, and a total of 72 species overall. 63 species were terrestrial birds, most of which were observed in all six years of her observations.
The semimonthly occurrence for...
The purpose of this paper is to provide my results about the nesting of Double-crested Cormorants (Phalacrocorax auritus) and Brandt's Cormorant (P. penicillatus) in Tillamook and Lane Counties.
This compilation is meant only to be a guide because it is imperfect. I gathered these citations during a single search of the sources cited in section B; ideally, I would have gone through all those sources again to perhaps find records that I missed or to correct errors that...
I conducted 14-22 waterbird and raptor censuses each year from 1992-1995 during late April or early May through October. I observed 44 waterbird and 13 raptor species, including hatch year individuals of seven waterbird species. The records for each census are given.
John H. Wampole's list of the birds of the Coos Bay area from 1958-59 is one of few such compilations from that region, and the only reasonably accessible one from its era except for Giesler (1952), which covered only the Cape Arago region. Wampole's list has been circulating informally as...
This paper supersedes and significantly revises my compilation of 1992. The focus remains on live birds seen on or from land, but special codes are now given for records of species only reported beached or at sea.
Additionally, confirmation codes are now listed for records of some rare species and...
The impetus for this Project began in 1968-1973 with birders at the Marine Science Center (MSC). But in the past 10 or so years the focus has shifted to a county group, Yaquina Birders & Naturalists. 120 individuals or couples have each contributed 100 or more records with 51% of...
The monthly occurrence of subspecies for 18 terrestrial species are given. The greatest differences in seasonal status appear to be among subspecies of the American Robin, Yellow-rumped Warbler, Savannah Sparrow, Song Sparrow, and Dark-eyed Junco.
There were 21 days with observations during 30 January-21 May 1974. Herons were already displaying on January 30, so nesting activity can occur much earlier than has been supposed. A yearling was often seen at the nests, but most nesting activity was by adults. Although eggs were laid in at...
The results of 703 observations are given; most of these were made in the 1930's by James Macnab, Jane Claire Dirks-Edmunds, Dorothy McKey-Fender, and others. These results are the most comprehensive throughout the year for any site above 1,000 ft in Lincoln County and hint that bird communities at sites...
612 Harlequin Duck records are given for Lincoln County, and another 74 records are listed for other coastal counties. In Lincoln County, Harlequins are found mostly in winter, there were often more males than females, the most ever counted was 14, and there is no indication that they nested.
In...
From 25 April through 30 October 1992, I conducted 14 waterbird and raptor censuses at Cabell Marsh. I observed 33 waterbird taxa and seven raptor species, including hatch-year individuals of five waterbird species. The records for each census are given.
These observations were sporadically made at my home in 1975-1977 and 1982. In spite of their casual nature, this article gives some information about the seasonal status of species at this site.
This is a continuation of Faxon and Bayer (1991), which summarized Faxon's 1973-1990 observations. In 1991, Faxon made observations during 168 days and recorded 111 species. Monthly frequencies of occurrence are given for each species.
In 1984-1986, Bayer made 171 and 67 waterbird censuses at West Pond and East Pond, respectively. From 1974 through June 1992, Bayer and others also made an additional 138 and 110 observations at West Pond and East Pond, respectively. A total of 48 waterbird taxa were reported at West Pond,...
There were 5,776 records during 1981-1986 observations, with 99% of these observations during Schrock's systematic 1982-1985 observations. He found 32 waterbird and 99 landbird species. 16% of the waterbird species were noted each year during 1982-1985, and 58% of the landbirds were recorded each year. Semimonthly summaries of the observations...

gender role ideology and self-reported drinking motivations on a college campus. A
questionnaire was administered to a sample of 735 university students. Gender...
Clearcut and shelterwood reproduction methods are both important, silviculturally viable reforestation tools for southwest Oregon. The ecology of local forests lends itself to the successful application of either method, in most cases; thus, choice of method is typically based on land management objectives, which integrate social and resource values, economics,...
A compilation of Oregon State University research work on computer-aided crosscutting (bucking) of trees into logs. Major considerations for deciding whether to adopt optimal bucking and steps to implement it are described. The bulletin references field studies which evaluated and tested prototype optimal bucking systems.
Trends in fee hunting in Oregon are examined, with particular emphasis on waterfowl in the western part of the state. Farmers with potential or existing waterfowl habitat in western Oregon were surveyed about their views on managing their lands for waterfowl. As incentives to such practices, they listed the financial...
Equations are presented that predict individual-tree 5-year diameter growth, outside bark, for 14 tree species in southwest Oregon. The data used to develop the equations came from 19,245 trees sampled from 391 stands in the study area. These equations express diameter growth as a function of diameter at breast height,...
Models of stand growth and yield must include an estimate of mortality. For individual-tree/distance-independent growth-and-yield models. it is necessary (1) to predict the probability of death of individual trees and (2) to keep stand projections within reasonable biological limits (e.g., the maximum basal area that the stand can achieve). In...
Production of hardwood lumber (mostly red alder) has been a small but growing part of the forest products industry in the Pacific Northwest. In laboratory tests, Rodewod® 200 EC plus borax protected alder at nearly all levels tested. Eight other chemicals provided some protection at the highest level tested. Fungal-stain...
The eruption of Mt. St. Helens provided the
opportunity to study secondary production of grazing insects in the context of disturbance. Two stream sites were chosen that significantly differed in how their
watersheds were impacted by the eruption. Clearwater Creek was catastrophically disturbed (physical alteration of habitat, loss of riparian...
Conflict over the management of public lands has increased markedly in the recent past. Forest Service personnel are responsible for making decisions about land allocations that are controversial and engender debate. This is a case study examining a conflict over the management of the Elk River drainage on the Siskiyou...
Oregon State University researchers conducted a survey in 1994 of non-industrial private forest (NIPF) landowners in western Oregon and western Washington. Private forests provide valuable ecological services, such as fish and wildlife habitat, and are also partially filling the gap created by recent reductions in federal timber harvest in the...
Equations for predicting tree height as a function of diameter outside bark at
breast height are presented for various tree species common to southwest
Oregon. Data for damaged and undamaged trees were analyzed with weighted
nonlinear regression techniques. The effects of specific damaging agents and
their severity on the height-diameter...
Adolescent pregnancy is a major social problem which results in negative psychological, medical, developmental,
economic and educational consequences for both mother and child. A review of the literature examined psychological and sociocultural factors and negative consequences associated with adolescent pregnancy. There has been little research on age specific differences between...
This paper comprises two major sections. In the first, tests of the influence of several application factors on efficiency of silvicultural herbicides are described for evergreen shrub, deciduous shrub, and herbaceous forest vegetation in Oregon and California. The second presents decision trees illustrating how to use the experimental results and...
The two literary touchstones of Charlotte Perkins Gilman and Willa Cather examined in this thesis anchored a larger discussion of the discourse about gender and sexuality during the First and Second Waves of feminism in America. "The Yellow Wallpaper" by Gilman deconstructed the notion of "femininity" manifested at the turn...
Untreated and preservative-treated fence posts were exposed in soil at a test site near Corvallis, OR. Several species, including western juniper and Osage-orange, showed exceptional natural durability. Preservative treatment generally extended the useful life of the posts, but the degree of protection varied with the chemical and the application method.
Three equations for predicting tree height as a function of diameter (outside
bark) at breast height are presented for six species found in coastal regions of
the Pacific Northwest. Foresters can use these “height–diameter” equations
to avoid the time-consuming task of measuring heights of all individual trees
in an inventory,...
Work-study guidelines were developed using field data from thinning sites in the Oregon Cascade Range. Regression of detailed time study and shift-level data predicted harvesting production rates. Statistical analysis showed the relative difference in the discriminating power between shift-level studies versus detailed time studies. Indicator variables tested if there were...
Naturally durable woods have a variety of commercial uses. Natural resistance to decay has been evaluated in field and laboratory tests of wood from many species, but there are few places where commercial wood users can find comparative assessments of natural durability. In this report, previous studies have been used...
Production rates and costs for skyline harvesting were examined over a range of residual thinning intensities, operational methods, and sites. The sites included three stands of 40- to 50-yr-old Douglas-fir on the Willamette National Forest in the Cascade Mountains of Oregon. Three silvicultural treatments were studied at two sites, and...
Logging planning and layout costs were examined for commercial thinning of 40- to 50-yr-old stands of Douglas-fir on the Willamette National Forest in the Cascade Mountains of Oregon. The study consisted of four replications of three silvicultural treatments. Thinning involved three types of logging systems: mechanized cut-to-length (a combination of...
Hann and Scrivani (1987) developed dominant height growth equations for Douglas- fir in southwest Oregon using stem analysis data sets with an upper age of approximately 125 years at breast height. The objective of this study was to determine whether these equations could be extrapolated for ages of 250 years...
Largest crown width (LCW) equations for stand-grown trees were developed for 14 tree species found in western Oregon. The equations are used in the growth-and-yield model ORGANON and in the stand-visualization program VIZ4ST. They were constructed such that LCW equals the maximum crown width
of open-grown trees when the crown...
