Abstract "Seeking Refuge" examines the history of migratory waterfowl management along the Pacific Flyway, the westernmost of four main migration routes in North America. Drawing on approaches from historical geography and environmental history, this study shows how wildlife officials developed migratory bird refuges in Oregon and California, where over 60 percent of Pacific Flyway waterfowl winter. During the early-twentieth century, reclamation and river diking eliminated most of the wetlands in the birds' wintering range. Bird enthusiasts such as bird watchers and duck hunters successfully lobbied for the creation of wildlife refuges in a few areas along the flyway. These early refuges failed to protect waterfowl habitat and they were severely degraded by reclamation. In the 1930s and 1940s, the U.S. Fish and Wildlife Service (FWS) and its predecessor, the Bureau of Biological Survey, undertook an ambitious program to resurrect these sanctuaries and to create new ones. Many farmers opposed these refuges out of fear that waterfowl would damage crops. To respond to these concerns and to ensure an adequate food supply for the birds, the FWS raised rice, barley, and other grains. The agency adopted many of the technologies of modern, industrial agriculture including synthetic herbicides and insecticides such as 2, 4-D and DDT. By the 1960s, the refuges had become largely mirrors of the surrounding irrigated farmlands, the main difference being that the FWS raised grain for waterfowl rather than for market. Refuges could not escape the agricultural settings in which they were embedded. As units within the irrigated countryside, Pacific Flyway refuges were often at the mercy of nearby farmers and federal reclamation agencies. Poor water quality and insufficient supplies of water often hampered FWS efforts to manage refuges. In the late-twentieth century, reduced water supply due to diversions to California municipalities and to sustain endangered fish species affected the amount of water reaching refuges. This dissertation has other goals. First, it critiques the anthropocentrism of most historical geography by focusing on how political, cultural, and ecological factors affected wildlife. Second, it contributes to the literature on the state's role in environmental protection by investigating the overlapping, and often contradictory, spaces within which wildlife managers implemented environmental regulations.

Monitoring of Lost River and Shortnose Suckers at Shoreline Spawning Areas in Upper Klamath Lake, 1999 Prepared by: Rip S. Shively1 Mark F. Bautista2 Andre E. Kohler2 1 U. S. Geological Survey, Biological Resources Division Klamath Falls Duty Station 6937 Washburn Way Klamath Falls, OR 97603 2 Johnson Controls World Services Inc. NERC Operation Post Office Box 270308 Fort Collins, CO 80527 Executive Summary In 1999, we sampled Lost River { Deltistes luxatus) and shortnose ( Chasmistes brevirostris) suckers from 5 April to 17 June at five shoreline spawning locations in Upper Klamath Lake ( UKL). Trammel nets were set to encompass identified spawning areas and were fished approximately 1- 1.5 hours before sunset until 3 hours after sunset or until 20 or more fish were captured. A total of 808 Lost River and 19 shortnose suckers were captured from Sucker, Silver Building, Ouxy, and Boulder springs, and Cinder Flats. The majority of Lost River suckers were captured at Cinder Flats ( 35%) and Sucker Springs ( 34%), followed by Ouxy Springs ( 16%), Silver Building Springs ( 12%), and Boulder Springs ( 3%). Males dominated the catch at all sites, but the sex ratios at Cinder Flats and Silver Building Springs were particularly skewed towards males. We recaptured 32 Lost River suckers that had been tagged during previous years sampling efforts. All of these fish, with the exception of two fish tagged at Ball Point in July, were originally tagged during the spawning season at shoreline spawning areas in UKL. This information provides further evidence that distinct stocks of Lost River suckers exist based on spawning location ( i. e., UKL and Williamson River). We also recaptured 23 Lost River suckers that were tagged in 1999 at shoreline spawning areas. Approximately half of these fish were recaptured at different locations than tagged indicating these fish were moving between spawning areas. The size offish captured at shoreline spawning areas decreased as the spawning season progressed, although the decrease in size was not as dramatic as reported in previous years. A limited number of shortnose suckers were captured at shoreline spawning areas in 1999, with a majority sampled after 1 May. Previous data for shortnose suckers at these sites is limited with respect to size, timing of spawning, sex composition, and relative numbers. Continuation of systematic sampling efforts at shoreline spawning areas will provide valuable information on the demographics and life history of Lost River and shortnose suckers utilizing these areas.

Geological Survey, Biological Resources Division through the Western Reservoirs Initiative. Introduction Severe water quality problems in Upper Klamath Lake ( UKL) have led to critical fisheries concerns for the region. Historically, UKL was eutrophic but has become hypereutrophic ( Goldman and Home 1983) presumably due to land- use practices within the basin ( USFWS 1993). As a result, the algal community has shifted to a monoculture of the blue- green algae Aphanizomemon flos- aquae and massive blooms of this species have been directly related to poor water quality episodes in UKL. The growth and decomposition of dense algal blooms in the lake frequently cause extreme water quality conditions characterized by high pH ( 9- 10.5), widely variable dissolved oxygen ( anoxic to supersaturated), and high ammonia concentrations (> 0.5 mg/ 1 unionized). In addition to water quality problems associated with A. flos- aquae, it is believed the loss of marsh habitat near the lake, timber harvest, removal of riparian vegetation, livestock grazing, and agricultural practices within the basin has contributed to hypereutrophic conditions. It is likely that these disturbances have altered the UKL ecosystem substantially enough to contribute to the near monoculture of A. flos- aquae. Investigations in 1913 documented the algal community as a diverse mix of blue- green and diatom communities, however, by the 1950' s A. flos- aquae was dominant ( USFWS 1993). The Lost River sucker ( Deltistes luxatus) and shortnose sucker ( Chasmistes brevirostris) are endemic to the Upper Klamath Basin of California and Oregon ( Moyle 1976). Declining population trends for both species were noted as early as the mid- 1960' s, however, the severities of the population declines were not evident until the mid- 1980' s. In 1988 the U. S. Fish and Wildlife Service listed both Lost River and shortnose suckers as endangered. Suspected reasons for their decline included damming of rivers, dredging and draining of marshes, water diversions, hybridization, competition and predation by exotic species, insularization of habitat, and water quality problems associated with timber harvest, removal of riparian vegetation, livestock grazing, and agricultural practices ( USFWS 1993). The U. S. Geological Survey, Biological Resources Division ( BRD) has been conducting field investigations on Lost River and shortnose suckers in UKL since 1994. The majority of these sampling efforts have focused on catching fish in UKL and the Lower Williamson River. Sampling in the Lower Williamson River focused on developing indices of relative abundance of Lost River and shortnose suckers. In 1999, Oregon State University continued sampling in the Lower Williamson River fishing trammel nets from April to August at four standardized locations. In addition to sampling efforts in the Lower Williamson River, BRD crews conducted periodic sampling at several shoreline spawning areas on the east side of UKL. This sampling was beneficial because it provided information on species composition, size, and sex ratios of suckers utilizing these areas. However, temporal changes in abundance may have been missed because consistent sampling never occurred throughout the entire spawning season ( Perkins et al, In preparation). Recently, there has been increased concern on the effects of water level management in UKL on spawning suckers. Information is needed on the timing, relative abundance, and distribution of sucker spawning in UKL to make informed decisions with respect to management of lake elevation. In 1999, we conducted systematic trammel netting surveys at Sucker, Silver Building, Ouxy, and Boulder springs and Cinder Flats along the east shore of UKL. In addition, we sampled periodically at Barkley Springs and Modoc Point to determine if suckers were utilizing these areas for spawning. This report summarizes data collected in 1999 on shoreline spawning populations of Lost River and shortnose suckers with emphasis on timing, species composition, sex ratios, and relative abundance. Methods We conducted systematic trammel netting surveys at five locations along the east shore of UKL ( Figure 1). We began sampling at Cinder Flats, Sucker, Silver Building, and Ouxy springs in early April with Boulder Springs added to the list of sampling sites on 27 April. In addition to these sites, we periodically sampled at Barkley Springs and Modoc Point ( Table 1). We attempted to sample each site twice per week although certain sites were only sampled once per week when catch rates of suckers were low ( i. e., less than 5 fish per evening). Trammel nets were fished for about 4 hours ( approximately 1- 1.5 hours before sunset until 3 hours after dark) or until we captured 20 or more fish. Nets used at individual sites varied in length from 15- 30 m, were 1.8 m tall with two outer panels ( 30cm bar mesh), an inner panel ( 3.8 cm bar mesh), a foam core float line, and a lead core bottom line. Generally, we set 1- 2 nets starting at the shoreline and extending out to encompass the perimeter of the identified spawning area. Nets were checked at approximately 1 hour intervals and captured fish were cut from the inner mesh panel and placed in a mesh cage and processed within 2 hours. Suckers were identified by species and sex, measured to the nearest mm ( fork length), inspected for tags ( both PIT and Floy tags), and examined for physical afflictions ( e. g., presence oiLernaea spp. and lamprey scars). If a sucker did not have a PIT tag, one was inserted with a hypodermic needle along the ventral surface 1- 2 cm anterior of the pelvic girdle. The catch per unit effort ( CPUE) of adult Lost River suckers was calculated for individual sampling locations for each evening sampled. Because identified spawning areas varied in size we used different length trammel nets to encompass the spawning areas. We did not attempt to standardize CPUE based on length of trammel nets used at each location. Results We sampled shoreline spawning areas from 5 April - 17 June capturing a total of 808 Lost River suckers and 19 shortnose suckers from 5 sites ( Table 1). Lost River and shortnose suckers were captured at Sucker Springs, Silver Building Springs, Ouxy Springs, and Cinder Flats, while only Lost River suckers were captured at Boulder Springs. No suckers were captured at Barkley Springs and Modoc Point ( Table 1). The majority of Lost River suckers were captured at Cinder Flats ( 35%) and Sucker Springs ( 34%; Figure 2). Males dominated the catch at all sites and were generally smaller ( mean length = 538 mm) than females captured ( mean length = 596 mm). In particular, sex ratios ( males to females) were most skewed at Cinder Flats and Silver Building Springs ( Figure 3). Large females (> 650 mm) were captured at most sites, except Boulder Springs, and the size range offish captured over time remained similar with the exception that a fewer large individuals (> 600 mm) were captured in the late sampling period ( 1 May - 17 June) as compared to the early sampling period ( 6- 30 April; Figure 4; Appendix Figure A). The catch of shortnose suckers was limited at all sites sampled. Most ( 12 of 19) of the shortnose suckers were collected at Sucker Springs, with 1- 3 fish captured at Cinder Flats, Ouxy Springs, and Silver Building Springs ( Table 1). We identified 8 males and 8 females during the sampling period and were unable to determine sex for three individuals. The mean size of shortnose suckers was 360 mm ( range 289- 528 mm) similar to data reported by Perkins et al. ( In preparation) from Sucker, Silver Building, and Ouxy springs. We observed the highest CPUE of Lost River suckers at Cinder Flats ( mean CPUE= 12.7/ h) followed by Sucker Springs ( mean CPUE= 6.0/ h), Silver Building Springs ( mean CPUE = 2.8/ h), and Ouxy Springs ( mean CPUE= 2.4/ h) ( Figure 5). On three occasions at Cinder Flats, 20 or more suckers were captured within an hour or less resulting in the termination of sampling for the evening. CPUE was calculated for sampling dates at Boulder Springs ( mean CPUE= 1.4/ h), although comparisons with other sites is not applicable because this site was not initially included in systematic sampling efforts. We did not calculate CPUE for shortnose suckers. We captured a total of 32 Lost River and 2 shortnose suckers that were tagged during previous years sampling efforts. The majority ( 96%) of these fish was originally tagged at shoreline locations ( Table 2), which is consistent with historical recapture data ( Appendix Table A). Two Lost River suckers were originally tagged at Ball Point in UKL in July, after the spawning season. In addition, most Lost River suckers were recaptured before 1 May, including 15 fish that were collected at Sucker Springs during two sampling occasions in March ( Figure 6). We also recaptured a total of 21 Lost River suckers that were tagged in 1999 at shoreline spawning areas. Approximately half of these fish were recaptured at different areas than where they were tagged, indicating that some suckers are moving between spawning areas within the season ( Table 3). Discussion Our sampling indicated the spawning period for Lost River suckers lasted from mid- March through the beginning of June at shoreline spawning areas in 1999. The catch of Lost River suckers was dominated by males at all sites sampled, particularly at Cinder Flats and Silver Building Springs. Perkins et al., ( In preparation) reported skewed sex ratios at shoreline spawning locations following the fish kills that occurred in UKL from 1995- 1997. However, the ratios we observed were considerably higher than those reported by Perkins et al., ( In preparation). At this time we are unable to determine the reason for the sex ratios observed. It is possible that males remain longer at the spawning areas than females making them more vulnerable to capture. Perkins et al., ( In preparation) observed spawning acts and reported that males remained near the actual site where spawning occurs while females move onto the spawning site only when ready to spawn. We captured 23 Lost River suckers twice in 1999 and all but one of these fish were males. However, it is difficult to determine if this percentage is due to males remaining at these sites longer than females or a reflection of the existing sex ratios. Another possible explanation could be the large numbers of males in the catch are from the 1991- 1993 year classes and females from these year classes have yet to be recruited into the adult population. The majority of males captured ( 81%) were between 475 - 574 mm. Age and growth information from Lost River suckers collected during the 1996- 1997 fish kills indicate these fish would be between 5- 9 years old ( USGS, BRD, 10 unpublished data). Perkins et al., ( In preparation) reported that male Lost River suckers migrating up the Williamson River begin to be recruited into the adult population starting at age 4+, while females did not begin to mature until age 7+ . These data were based on examining length frequency distributions and noting when fish from the 1991 year class, which is presumed to be a strong year class, began showing up in trammel net catches. Fish from the 1991 year class would have been age 8+ in 1999. Buettner and Scoppetone ( 1990) examined opercles from Lost River suckers collected during the 1986 fish kill in UKL and reported that individuals matured between 6- 14 years of age with the peak being 9 years. It is possible that in the next few years more females from the 1991- 93 year classes will be recruited into the adult population spawning at shoreline areas. Our data provides additional evidence that distinct stocks of Lost River suckers may exist based on fidelity to spawning area. Of the 32 suckers we recaptured from previous years sampling efforts, all but two were originally tagged at shoreline spawning locations. The two fish that were not originally tagged at shoreline spawning locations were captured at Ball Point in July and were not presumed to be spawning in this location. Perkins et al. ( In preparation) reported that of 316 Lost River and 11 shortnose suckers recaptured at shoreline spawning areas all were originally tagged at shoreline spawning locations. Continuation of systematic sampling at both shoreline spawning areas and the Williamson and Sprague rivers will continue to provide information on potential separation of spawning populations. The majority of recaptured fish were tagged during the first half of our sampling efforts including 13 fish that were recaptured on 25 March while sampling with Larry Dunsmoor of the Klamath Tribes. Historically, the majority of sampling effort at 11 shoreline spawning locations occurred prior to 1 May, which may explain why most recaptures were collected during the early part of our sampling period. In fiiture years, we plan to continue systematic sampling through June to determine if temporal aspects of spawning remain consistent between years. The size offish captured at shoreline spawning areas decreased as the spawning season progressed, particularly near the end of our sampling period, although the decrease was not as dramatic as reported by Perkins et al., ( In preparation). It is possible that individual timing of Lost River sucker spawning is affected by size. Scoppettone et al., ( 1986) observed that smaller, younger cui- ui ( Chasmistes cujus) at Pyramid Lake spawned at the end of the spawning season. We believe further investigation is needed to determine if differences in spawning timing among individuals is due to size or related to stock differences. A limited number of shortnose suckers were captured in 1999. Sampling continued well into June and was sufficient to detect spawning concentrations of shortnose suckers at these sites. Based on previous sampling conducted at shoreline spawning areas, there appears to be a decreasing trend in the number of shortnose suckers captured at these sites ( Perkins, et al., In preparation). Our sampling efforts at shoreline spawning areas on the east side of UKL represents the first time these areas have been systematically sampled during the spawning season. Continuation of systematic sampling at these areas is important to provide information on species composition, timing and duration of spawning, fidelity to spawning areas, sex ratios, size distribution, and relative abundance. How these 12 population characteristics change over time will also provide important insights into the population stability of Lost River and shortnose suckers in UKL. 13 Literature Cited Buettner, M.

Executive Summary The jawless lampreys are remnants of the oldest vertebrates in the world. Oregon has somewhere between eight and a dozen species of these primitive fishes. Their taxonomy is obscure because different species tend to look very similar through most of their life cycle, and they have not been well-studied in Oregon. Lampreys occur in the Columbia Basin, including the lower Snake River, along the Oregon coast, in the upper Klamath Basin, and in Goose Lake Basin in southeastern Oregon. They all begin life in fresh water where juveniles burrow into silt and filter feed on algae. As some species approach adulthood they migrate to the ocean or to lakes where they briefly become ecto-parasites, feeding on other live fishes by attaching to them with sucker disc mouths. Other species remain non-parasitic. In addition to some enigmatic species identities, we generally have very little information about the detailed distributions, life histories and basic biology of lampreys. Lampreys became a conservation concern in the early 1990s when tribal co-managers and some Oregon Department of Fish and Wildlife (ODFW) staff noted that populations of Pacific Lampreys, Lampetra tridentata, were apparently declining to perilously low numbers. Pacific Lampreys were listed as an Oregon State sensitive species in 1993 and were given further legal protected status by the state in 1997 (OAR 635-044-0130). Lamprey status is difficult to assess for several reasons: 1) Most observations of lampreys in fresh water are of juveniles and it is difficult to tell the various species apart, even to the extent that the various species are currently clearly designated; 2) Data on lamprey is only collected incidental to monitoring of salmonids. The design and efficiency of the data collection effort is not always adequate for lampreys; and 3) We have very few historic data sets for lampreys. Therefore we often cannot determine how the abundances and distributions we see now compare with those in the past. The limited data that we have suggests that lampreys have declined through many parts of their ranges. The most precipitous declines appear to be in the upper Columbia and Snake basins where we have some historic data from mainstem dam counts. Pacific Lampreys have declined to only about 200 adults annually passing the Snake River dams. We also have evidence of declines of Pacific Lampreys in the lower Columbia and on the Oregon coast, although our data is quite limited. We have little to no information about any of the other species of lampreys. We are not even sure whether some of the recognized species, like the River Lamprey (L. ayresi), is still present in Oregon. This paper concludes with a Problem Analysis for Oregon lampreys. Our biggest problem is poor information, ranging from not knowing basic species identity to having inefficient or no systematic monitoring of lamprey abundance and distribution. ODFW continued an annual harvest on Pacific Lamprey in the Willamette Basin in 2001, but we lack the necessary information to assess the affects of the harvest on the population. Major habitat problems that affect lampreys include upstream passage over artificial barriers, a need for lamprey-friendly screening of water diversions, and urban and agricultural development of low-gradient flood plain habitats.

Abstract The Secretaries of Agriculture and the Interior propose limited changes to language about how to demonstrate that projects follow the Aquatic Conservation Strategy, part of the Northwest Forest Plan. Projects needed to achieve Northwest Forest Plan goals have been delayed or stopped due to misapplication of certain passages in the Aquatic Conservation Strategy. The agencies are responding to the underlying need for increased agency success planning and implementing projects, to the extent that the current wording has hindered the agencies ability to follow Northwest Forest Plan principles and achieve its goals. The goals of the Northwest Forest Plan cannot be achieved without project implementation. Three alternatives are considered in the Final Supplemental Environmental Impact Statement, No Action, the Proposed Action, and Alternative A. No Action would not change existing language within the Aquatic Conservation Strategy. The Proposed Action and Alternative A would make l

We analyzed the reproductive biology and demographics of the Lost River sucker Deltistes luxatus and shortnose sucker Chasmistes brevirostris, two endangered species endemic to the upper Klamath Basin of Oregon and California, from 1984-1997. Lost River suckers had distinct river and lake shoreline spawning stocks, and individuals of both species commonly spawned in consecutive years. In the Williamson River and lower Sprague River, spawning migration by both species occurred mainly during a 5-week period that started within the first three weeks of April and peaked between mid April and early May, although a separate, earlier (mid March) run of Lost River suckers may also spawn in the upper Sprague River. Migration of both species was several times higher at dawn (0500-0730 h) and evening (1800-2200 h) than other times of the day. Peak migrations almost always corresponded to peaks in water temperature, usually at 10-15°C. Lost River suckers were captured at springs along the east shore of the lake from late February through mid May, with peak spawning usually in mid March to mid April. Shortnose suckers were generally captured at the springs from late March through late May, but the time of peak spawning was not determined. Size and age at maturity was determined by recruitment from a strong year class (1991). Male Lost River suckers began recruitment into the adult population at age 4+ (375-475 mm). Substantial recruitment of females did not begin until age 7+ (510-560 mm). Male and female shortnose suckers began recruitment at age 4+, with the majority offish recruited by age 5+. Males recruited at 270-370 mm; females recruited at 325-425 mm. Fecundity estimates were quite variable ranging from 44,000-236,000 eggs per female Lost River sucker and 18,000-72,000 eggs per female shortnose sucker. In 1984 and 1985, the spawning populations of both species were dominated by large, old individuals, with little indication of recent adult recruitment. In the next 13 years, only one strong year class (1991) recruited into the spawning populations of both species. This year class temporarily boosted population numbers, but annual fish kills from 1995 to 1997 eliminated most adults of both species. Associated with poor water quality caused by the proliferation and decay of blue-green algae Aphanizomenonflos-aquae, these fish kills raise concern that alterations to the lake ecosystem over the past several decades have Perkins et al. Lost River and shortnose suckers 5 increased the magnitude and frequency of poor water quality. As a result, mortality rates of all life stages may have increased, thereby disrupting the species' life history pattern and potentially decreasing long-term population viability. Introduction The Lost River sucker Deltistes luxatus and shortnose sucker Chasmistes brevirostris are large, long-lived suckers endemic to the upper Klamath Basin of Oregon and California. Both species are typically lake dwelling but migrate to tributaries or shoreline springs to spawn (Moyle 1976, Scoppettone and Vinyard 1991). Once extremely abundant (Cope 1884, Gilbert 1898), both species have experienced severe population declines and were federally listed as endangered in 1988 (USFWS 1988). Much of the original habitat of these suckers has been destroyed or altered by conversion of lake areas to agriculture, dams, instream flow diversions, and water quality problems associated with timber harvest, loss of riparian vegetation, livestock grazing, and agricultural practices (USFWS 1988). Knowledge of the life history of Lost River and shortnose suckers is fundamental to recovery of these species. The objective of this report was to present the results of studies conducted from 1987-1998 on the reproductive biology and demographics of Lost River and shortnose suckers, and to compare these results with earlier unpublished data. Study Sites Studies were conducted on Upper Klamath Lake and the lower Williamson-Sprague river system (Figure 1). These waters form the upper portion of the Klamath River Basin in south-central Oregon and represent most remaining native habitat of Lost River and shortnose suckers. Upper Klamath Lake is a remnant of pluvial Lake Modoc that included eight major basins and encompassed 2,839 km2 (Dicken 1980). Today, Upper Klamath Lake serves as a storage reservoir that provides water for agricultural irrigation, waterfowl refuges, instream flow requirements of anadromous fish, and hydroelectric power generation. At full capacity, the lake covers approximately 360 km2 and has an average depth of 2.4 m. Most deeper water (3-12 m) is restricted to narrow trenches along the western shore. Lake elevation is controlled at the outlet by Link River

ABSTRACT Phase VI of the School-Based Klamath Restoration Project (319h) is a collaborative effort between seven Siskiyou County schools, the Siskiyou County Office of Education (SCOE), and the United States Fish and Wildlife Service (USFWS). The objectives of the project include: ? Expanding hands-on field science watershed education. ? Encouraging a sense of resource stewardship among students at all grade levels. ? Collecting quality data for inclusion in the 319h data base. ? Teaching applications of the scientific method. ? Providing on-going inservice training for teachers to increase the effectiveness of the project. Project tasks that were completed include acquisition and analysis of Klamath River Watershed Data, including river water temperatures, river cross sectional profiles and spawning ground surveys. Descriptions of methodology are included in the report. Many other watershed-related projects were undertaken by schools. In some cases the field data was collected and compiled by agency personnel. The spawning ground survey data collected by student volunteers was part of a project conducted by the California Department of Fish and Game and the U.S. Forest Service. Although a substantial amount of excellent work has been accomplished by the schools, the opportunity exists to improve the program at all levels. Increased field and technical support is needed to successfully integrate the goals of the project. Computer training for teachers and students is an essential component of the project, which would allow analysis of data and creation of web sites within classrooms. Data analysis and reporting is the critical component of the project that would provide students with a complete understanding of scientific research methodology. Providing a forum for communication between the 319h participants is another important area of the project that needs to be expanded. Travel time, mountainous topography, and intense winter storms can be barriers to travel in Siskiyou County. Communication helps to increase the level of standardization of data collection and transfer and gives teachers a chance to share successful ideas. Communication also sustains the positive momentum of the project, reinforcing the idea of working as a team towards establishing common goals for watershed education.

This study examined the sources of job satisfaction and dissatisfaction for classified employees in a large public suburban school district. The population included randomly-selected bus drivers, custodians, school and non-school secretarial employees, instructional assistants, maintenance workers, food service personnel and technical employees. Three research questions were posed: (a) What are the primary sources of job satisfaction and dissatisfaction for classified employees? (b) Is there a significant difference in job satisfaction among the specific categories of classified employees? (c) Are demographic/personal variables of classified employees related to overall job satisfaction? The study incorporated both qualitative and quantitative methodology. Focus groups were convened to identify satisfiers and dissatisfiers, which then served as a basis for questionnaire development.Sixty-four individuals participated in focus group discussions; 490 questionnaires were returned for a response rate of 78%. The self-designed questionnaire contained 100 job variables, including a single direct question of overall satisfaction. The assessment also included twelve demographic/personal variables and two open-ended questions. Data were statistically analyzed using ANOVA, ANCOVA, the Chi square test, multiple regression, and paired comparisons. The primary job satisfiers for all classified employees were: co-workers, students, work itself, work variety, autonomy, and work schedule. Dissatisfiers were: work overload, district policies, and job insecurity. There was a significant difference in job satisfaction among employee groups. There was also a significant difference in job satisfaction for the demographic variables of gender, work setting, and number of hours worked, even after the influence of job category was eliminated. The research suggests that there are issues which influence the job satisfaction of classified employees. In their quest for excellence, school district administrators, and business leaders, alike, can benefit from listening to the needs and recommendations of their support personnel.

This study focuses the effects of demographic characteristics, health status, income, work attitudes, and leisure activity involvements have on satisfaction in retirement and the retirement timing decision. The review of the literature revealed that no single variable alone is the predictor of retirement satisfaction and the timing of the retirement decision. Therefore, a conceptual model was developed to measure the two central research questions. The conceptual model is based on five categorical factors as the determinants of retirement satisfaction and timing. The five main factors in the model are: demographic characteristics, health status, income level, work attitudes and leisure activity involvement. Multi-item scales were developed from data on 231 retirees and 908 older workers. The two samples were currently and/or formerly employed with the same high technology, Fortune 500 firm. The adequate number of both males and females in the two samples provide the opportunity to do a comparative analysis between men and women. It was clear from the data analysis that the independent variables selected explained a low percentage of the variance in both retirement satisfaction and the timing of the retirement decision. The comparative analysis between men and women did suggest that the retirement experience for women is different from men. The findings suggest that the variables that contribute to the two outcomes lay outside the conceptual model. However, the findings suggest that satisfaction in retirement is partially determined by gender, health status, income, work attitudes and leisure activity involvement. The research findings indicate variables that contribute significantly to the timing of the retirement decision, but no one variable or combination of variables have strong predictive power. This implies that the independent variables found in the literature are not the key determinants of retirement satisfaction or retirement timing. Policy implications and suggestions for future research are discussed.

This project examined cyclist red light running behavior using two data sets. Previous studies of cyclist compliance have investigated the tendencies of cyclists to run red lights on the whole by generalizing different maneuvers to their end outcome, running a red light. This project differentiates between the different types of red light running and focuses on the most egregious case, gap acceptance, which is when a cyclist runs a red light by accepting a gap in opposing traffic. Using video data, a mathematical model of cyclist red light running was developed for gap acceptance. Similar to other studies, this analysis utilized only information about the cyclist, intersection, and scenario that can be outwardly observed. This analysis found that the number of cyclists already waiting at the signal, the presence of a vehicle in the adjacent lane, and female sex were deterrents to red light running. Conversely, certain types of signal phasing, witnessing a violation, and lack of helmet increased the odds that a cyclist would run the red light. Interestingly, while women in general are less likely to run a red light, those who witnessed a violation were even more prone that men who had witnessed a violation to follow suit and run the red light themselves. It is likely that the differing socialization of women and men leads to different effects of witnessing a previous violator. The analysis also confirmed that a small subset of cyclists, similar to that found in the general population, are more prone to traffic violations. These cyclists are more willing to engage in multiple biking-related risk factors that include not wearing a helmet and running red lights. Although the model has definite explanatory power regarding decisions of cyclist compliance, much of the variance in the compliance choices of the sample is left unexplained. This points toward the influence of other, not outwardly observable variables on the decision to run a red light. Analysis of survey data from cyclists further confirms that individual characteristics not visible to the observer interact with intersection, scenario, and visible cyclist characteristics to result in a decision to comply (or not) with a traffic signal. Furthermore, cyclist characteristics, in general, and unobservable individual characteristics, specifically, play a larger role in compliance decisions as the number of compliance-inducing intersection traits (e.g. conflicting traffic volume) decrease. One such unobservable trait is the regard for the law by some cyclists, which becomes a more important determinant of compliance at simpler intersections. Cyclists were also shown to choose non-compliance if they questioned the validity of the red indication for them, as cyclists. The video and survey data have some comparable findings. For instance, the relationship of age to compliance was explored in both data analyses. Age was not found to be a significant predictor of non-compliance in the video data analysis while it was negatively correlated with stated non-compliance for two of the survey intersections. Gender, while having significant effects on non-compliance in the video dataset, did not emerge as an important factor in the stated non-compliance of survey takers. Helmet use had a consistent relationship with compliance between the video and survey datasets. Helmet use was positively associated with compliance in the video data and negatively associated with revealed non-compliance at two of the survey intersections. When coupled with the positive association between normlessness and stated willingness to run a red light, the relationship between helmet use and compliance solidifies the notion that a class of cyclists is more likely to consistently violate signals. It points towards a link between red light running and individuals who do not adhere to social norms and policies as strictly as others. Variables representing cyclists and motorists waiting at the signal were positively related to signal compliance in the video data. While an increased number of cyclists may be a physical deterrent to red light running, part of the influence on compliance that this variable and the variable representing the presence of a vehicle may be due to accountability of cyclists to other road users. This relationship, however, was not revealed in the stated non-compliance data from the survey. Efforts to increase cyclist compliance may not be worth a jurisdiction's resources since nearly 90% of cyclists in the video data were already compliant. If a problem intersection does warrant intervention, different methods of ensuring bicyclist compliance are warranted depending on the intersection characteristics. An alternative solution is to consider the applicability of traffic laws (originally designed for cars) to bicyclists. Creating separation in how laws affect motorists and cyclists might be a better solution for overly simple types of intersections where cyclists have fewer conflicts, better visibility, etc. than motorists. Education or other messaging aimed at cyclists about compliance is another strategy to increase compliance. Since cyclists appear to feel more justified in running red lights at low-volume, simple-looking intersections, it would probably be prudent to target messaging at these types of intersections. Many cyclists are deterred by high-volume and/or complicated looking intersections for safety reasons. Reminding cyclists of the potential dangers at other intersections may be a successful messaging strategy. Alternatively, reminding cyclists that it is still illegal to run a red light even if they feel safe doing so may be prudent. Additionally, messaging about the purpose of infrastructure such as bicycle-specific signals or lights that indicate detection at a signal may convince cyclists that stopping at the signal is in their best interest and that the wait will be minimal and/or warranted.

At the beginning of the twentieth century, transient laborers in Portland, Oregon faced marginalization and exploitation at the hands of the classes that relied on them for their own prosperity. Portland at this time was poised to flourish as a major population and industrial center of the American West. The industries that fueled the city's growth were dependent on cheap and mobile manual labor made available by the expansion of the nation's railroads. As the city prospered and grew, the elite of the city created and promoted an image of Portland as an Eden of material abundance where industriousness and virtue would lead inevitably to prosperity. There was no room in Portland's booster image for unemployed but otherwise able-bodied men that fueled this prosperity but saw no benefit from it. Their very existence challenged both the image of the city itself, and broader and deeper pillars of American identity. The response to the presence of this mobile, underemployed and largely white male labor class by Portland citizens and institutions was driven by, and in turn helped shape, competing mythologies of both the American West and American masculinity at a time when the country was struggling to define and redefine these constructs. Examining these floating men through their portrayal in popular culture, laws, and charitable efforts of the time exposes a deep anxiety about the notions of worth, gender, and American virtue.

Gender equity has been a national and global aim for over half a century (Ceci & Williams, 2007; National Center for Education Statistics, 2003; National Science Board, 2008). While gains have been made, one area where inequity remains is spatial reasoning ability, where a large gender gap in favor of males has persisted over the years (Else-Quest, Linn, & Shibley Hyde, 2010; National Science Board, 2008; Ruble, Martin, & Berenbaum, 2006). This gender gap in spatial reasoning has had substantial societal impact on the career interests of females in areas of Science, Technology, Engineering, and Math (STEM), contributing to the larger societal need to engage non-dominant groups in these fields to reduce outsourcing (Ceci & Williams, 2007; Jaschik, 2007; Wai, Lubinski, & Benbow, 2009; White, 1992). Both spatial reasoning ability and STEM career interest have been related to science museum visits (Hamilton, Nussbaum, Kupermintz, Kerkhoven, & Snow, 1995; Salmi, 2001, 2002). However, researchers have also found a gender gap in favor of males in regard to science museum attendance and experiences once at the museum (Borun, 1999; Crowley, 2000). There are many suggestions for increasing female engagement at science museums and creating equitable experiences, but few have been systematically studied (Kekelis, Heber, & Countryman, 2005; Koke, 2005; Maher, 2005; Taylor, 2005). This research investigated gender equitable exhibit development by enhancing a geometry exhibit with several female-friendly design features and analyzing video data to determine the effects on girls' engagement and social interactions with their caregivers. The findings suggest that incorporating several female-friendly design features leads to significantly higher engagement for girls (evidenced by greater attraction and time spent). This study also looked for any unanticipated negative effects for boys after incorporating the female-friendly design features. It is encouraging that this study was unable to detect any unintended negative effects for boys; however, such non-significant results are inconclusive and should not dissuade future research and design teams from continuing to check for unanticipated ill effects of female-friendly design features for boys. While the positive effects for girls were significant, it is important to note that they were not significantly more positive for girls than for boys; further research is needed to determine whether the female-friendly design features create a more equitable experience for girls, or a more positive experience for everyone. This study did not identify any significant differences in parent-child verbal social interactions between the two versions of the exhibit; however, the pattern of results suggests that gender discrepant parent explanations, as found by Crowley, 2001 in a children's museum, may be less of a concern for girls in science centers, providing an interesting area for future study. This research presents evidence to support incorporating female-friendly design features in future science exhibit development projects, and indicates areas where future studies are still needed to gain a deeper understanding of their effects.

Over the last forty years, the U.S. community college system has expanded, allowing disadvantaged groups greater access to higher education. With that expansion, a body of research has emerged examining community college students' educational outcomes. However, the research is limited in understanding the academic persistence of low-income students and community college student in particular. The purpose of this comparative, qualitative study is to explore some of the unanswered questions about how low income white and Latino students' experience academic persistence similarly and differently and understand how gender influences the challenges students may face during college. This study draws from interviews of 22 (11 White/11 Latino/a) low-income community college students at a rural, Hispanic-Serving Institution (HSI) in the West. All students share similar challenges because of their class constraints, but Latino/a students in particular face challenges of racism and discrimination that carried over into their college careers. Faculty and family are the key sources of support for all students, which mediate some of the challenges. Variation is seen between the experiences of males and females, as traditional gender roles are reinforced and maintained in the family. This study offers insights into how structural inequality creates barriers for students from their perspective and gives recommendations for practitioners on how to mediate some of these challenges and increase student persistence.

It is through the announcement and placement of various identities that one is able to enter into various types of social relations. Identity is a label used to describe a person in a particular situation as being a kind of social object. A person announces his identity and others place him as having this identity on the basis of his appearance. Structural relations have been defined as relations where one may enter by using a title, while interpersonal relations are entered by using a name or nickname. Structural identities place people in categories, while separating them from others in different categories. Names are used to identify an individual and thus, distinguish him from all other individuals. It has been the purpose of this thesis to gain an understanding of an empirical world (gay drinking places) through the application of the theoretical concept of identity as discussed by those in the interactionist perspective. The method of participant observation was used to gather the data for this investigation. The role of "participant-as- observer" was assumed. The observations were conducted in male gay drinking places in an urban area over a period of three months. Both informal and formal interviews were conducted with informants. It was found that in the gay drinking places there are different structural identities which may be announced and placed in order to enter into structural relations. In most situations these structural identities are announced and placed on the basis of appearance. Knowledge of these structural identities allows the exploration of the relations between those presenting a specific structural identity with those presenting the same structural identity and with those presenting different structural identities. While the announcement and placement of identities facilitates interaction, in some cases it may preclude interaction. Additionally, It is suggested that the various gay bars and taverns acquire imputed identities. The subject of identity transformation in the gay drinking places was also investigated. When a person new to the gay subculture is aspiring to the identity of gay regular, he must learn how to announce this identity. Gay drinking places serve as places where the individual may announce his intention of becoming a gay regular and where he may meet others who have the identity to which he is aspiring. In gay drinking places he enters into a coaching relationship with other gay regulars who serve as models for him, teach him how to appear, and define the various situations in which he finds himself. Names and nicknames are used to enter into interpersonal relations with others in the gay drinking places. In the gay drinking places, it was found that while a person's structural identity indicates that the person can be shown to be a specific type of person, it is a person's name or nickname which identifies him as an individual. In interaction, a name brings to mind various situationally relevant elements of biographical information. The biographical information which may be brought to mind is in many cases limited to information accumulated about the person's activities in the gay drinking places because last names are rarely used.

The decision to marry and choice of mate are two issues contemplated by most individuals during their lifetime. It is our belief that the manner in which an individual makes these decisions is a reflection of that individual’s level of emotional maturity. In our society, the right to enter into a marriage agreement is largely determined by chronological age. Our research problem began with the hypothesis that there is no direct relationship between chronological age and emotional maturity at the time of marriage. For our study, marriages were divided into two general categories: 1) teenage marriages in which at least one partner was 20 years of age or younger, and 2) adult marriages in which one partner was Z1 years of age or older. The three independent variables studied were: age, sex of respondent, and sex of spouse. The dependent variable was emotional maturity. Emotional maturity was operationally defined by a questionnaire consisting of 67 statements about why people decide to marry, and why they chose their particular spouse. A panel of 12 experts in the field of marriage counseling were asked to rate each statement on a seven point scale of maturity-immaturity. The range and mode for each statement was computed and used to construct a new questionnaire consisting of 30 statements. Emotional maturity was defined by the absolute difference between the individual respondent’s rating and the expert’s modal response. A sample population was selected using recently married individuals who had applied for marriage licenses in Multnomah County, Oregon. The second questionnaire was mailed to the respondents. A 2 x 2 x 2 factorial design was used to identify which variable or combination of variables accounted for any discrepancy. A multiple regression analysis and a F test were run to test the hypothesis of the study. The data received supported the null hypothesis. However, there were several conceptual and methodological limitations to the study which raise questions as to the reliability of the measuring instrument and use of the concept of emotional maturity.

Students' classroom engagement is a strong predictor of positive educational outcomes including academic achievement, GPA, and standardized test scores. Most existing research has focused on the role of quality parenting and teaching in the development of student engagement. However, some research has shown small, yet significant effects of influences from students' peer groups on the development of their engagement. The goal of this study was to explore whether some children are more susceptible to the effects of their peer groups, and to examine a series of possible factors that might amplify the influence of a target students peer group on the development of that students' own engagement over the course of an academic year. In a re-analysis of an existing data set (Kindermann, 2007), peer group profiles of student engagement were examined as predictors of changes in individual engagement from fall to spring. It was expected that peer groups' levels of engagement would vary in their predictive power for changes in students' own engagement over the school year, depending upon individual levels of peer relatedness, the number of peers with whom the student affiliates with, student perceptions of parental involvement, as well as person-to-group differences in engagement. Gender differences were expected to be non-significant. As expected, results from two sets of analysis indicate no significant gender differences in susceptibility to peer influence. Furthermore, results suggest that susceptibility to peer influence on school engagement may depend upon the number of peers with whom a student affiliates with, parental involvement, as well as person-to-group differences in engagement. However, contrary to expectations, results suggest that a student's susceptibility to peer influence may not depend upon self-reported peer relatedness. Details of the analyses, results, strengths, limitations, and implications for future research are discussed.

Existing research suggests that men and women develop differing sexual scripts that influence their behavior, interactions and emotions regarding sex. The objective of this project is to examine the experiences of men and women with formal sex education programs, especially in regards to information about: anatomy and biology, sexual responsibility and risk taking, sexual desire, virginity and abstinence, as well as to explore sources of sex education outside of school. Several studies suggest masculine sexual scripts dictate that men generally construct a more body-focused approach to sex, with an emphasis on competition, aggression and achievement. Conversely, emphasized feminine sexual scripts call for a more emotion-focused approach to sex that stresses self-control, resistance and sexual 'gatekeeping'. One of the explanations for this is adolescents' experience with formal sex education in school. Gendered messages in sex education that reproduce dominant sexual scripts have the potential to reinforce sexual double standards that affirm male desire and regulate female desire. Previous studies have determined school to be a place where individuals develop scripts that guide them through many aspects of social life. While one recent study has pointed to the existence of gendered messages in sex education films, there is little research on how men's and women's experiences with formal sex education influence their interaction with different sexual scripts. Additionally, this research recognizes that interaction with sexual scripts occurs in a multitude of settings over the life course, and although formal sex education is the focus of this analysis because of the explicit messages communicated to adolescents during a very formative stage, other more informal sources of sexual information (i.e. family, peers, and the internet) are explored in comparison with school-based sex education. The findings of this study indicate a gendered patter in access to sexual scripts, drawing from participants' accounts of their sex education experiences in school, as well as important differences in the messages, or scripts communicated to them about sex from friends, family and online. Most notably, men and women generally recount interaction with scripts that reinforce traditional masculine and feminine sexuality in formal, school-based sex education programs. However, sexual learning from more informal sources, like from families and the internet, indicate possible shifts in traditional gendered sexuality, especially for women.

This book-length manuscript is a collection of poems. They and it examine ecology as a state of being in and outside the body (or how, if at all, there is a secure distinction), species-based boundaries of the body, obsessions with immunity and chronic illness in biopolitical and gendered societal and perhaps inevitably thus linguistic structures, and what it means to participate in close reading while writing to contribute to the question of ecology as poetry. The central questions are in fact questions: what is the relationship between a deconstructive approach to identity creation and erasure through participation in poetry as a medium, a set of forms, and the site of the body's dilemma?

Research has consistently demonstrated strong relationships between high levels of adherence to traditional masculinity ideology and poor health and behavior outcomes (e.g., Levant & Richmond, 2007; O'Neil, 2008). Though recent studies have demonstrated support for theories of multiple masculinities or the idea that one's masculinity ideology is developed, maintained, and restructured according to one's social and environmental contexts (e.g., Smiler, 2004), understanding how male gender contributes to social problems within diverse communities, social groups, and contexts is not well established (Mankowski & Maton, 2010). The current study examined how individual and contextual variables predict change in level of adherence to traditional masculinity ideology among a diverse sample of incarcerated adolescent males convicted of felony crimes in the state of Ohio. In particular, while literature has described prison settings as an environment that ignores gender (e.g., Lutze & Murphy, 1999; Messerschmidt, 1993), the current study assessed the effectiveness of a strength-based program at successfully decreasing adherence to traditional masculinity within two of the four participating juvenile justice facilities in ODYS. Using hierarchical linear modeling informed by a qualitative follow-up sequence design, study found younger adolescents and African American youth with low levels of ethnic pride to have higher levels of adherence to traditional masculinity at the beginning of the study compared to older adolescents and White youth or African American youth with high levels of ethnic pride. Interestingly, age did not predict changes in levels of adherence to traditional masculinity ideology over time, however, White youth's level of adherence increased over time and African American youth's level of adherence remained relatively stable. Moreover, youth with good attendance in the program experienced less dramatic increases in adherence to traditional masculinity compared to those with poor attendance. Thematic analysis of qualitative data supports the study's finding that program participation predicts changes in levels of adherence to traditional masculinity ideology over time. In addition to providing support for quantitative findings, the thematic analysis highlights some potential gaps in the quantitative assessment of masculinity ideology that must be considered in future research. For example, youth describe an alternative ideal form of masculinity, sometimes characterized by the youth as "man up," that provides a level of flexibility that is counter to that of traditional masculinity. Moreover, the qualitative findings also raise questions about the validity of the survey measure of masculinity (AMIRS; Chu, 2005) for use with African American and incarcerated youth. Finally, the study supports theories of multiple masculinities and offers preliminary evidence that gender specific, strengths-based programming can influence adherence to traditional masculinity ideology among youth in juvenile justice facilities.
