  Citation × Citation Citation Abstract Copy Title: Adjustment to College among Lower Division Students with Disabilities: An Exploratory Study Author: McNulty, Kristy Lee Ann Year: 2014 This study utilized a quality of life framework of psychosocial adaptation to explore relationships among college stress, functional limitations, coping strategies, and perceived social support in adjustment to college among first-year and second-year undergraduate students with disabilities, based on specific hypothesized relations. College adjustment outcomes included: life satisfaction, academic performance, and psychosocial-emotional adjustment to college. A nonprobability sample of 103 first-year and second-year undergraduate college students with disabilities participated in the study. Respondents were registered with an office of support services for students with disabilities at a public, four-year university, located in the Pacific Northwest of the United States. Respondents were recruited by responding to an e-mail requesting participation in an online, web-based survey. Eight self-report measures included: (a) Participant Survey (developed by the researcher to collect socio-demographic information, (b) College Stress Inventory (CSI; Solberg, Hale, Villarreal, & Kavanagh, 1993), (c) Disability Functional Limitations Scale (DFLS) (developed by the researcher), (d) Brief COPE; Carver, 1997, (e) Social Support Appraisals-Revised (SSA-R) scale; Vaux et al., 1986), (f) Satisfaction with Life Scale (SWLS; Diener, Emmons, Larsen, & Griffin, 1985), (g) Grade Point Average-Scale (GPA-S; adapted by the researcher from a self-reported grading scale), and (h) Student Adaptation to College Questionnaire (SACQ; Baker & Siryk, 1999). Data were analyzed using descriptive and correlational procedures. Bivariate analysis suggested that all predictor variables (i.e., college stress, functional limitations, engagement coping, and perceived social support) were significantly associated with student adjustment to college. Hierarchical multiple regression suggested mostly direct (i.e., main) effects for engagement coping and perceived social support. No interacting role for either engagement-type coping or perceived social support was suggested, except for the following: Engagement-type coping moderated the relationship between disability-related functional limitations (as measured by increased restrictions in the ability to perform daily routines, activities, and life roles) and adaptation to college, as measured by life satisfaction. Analyses of socio-demographic variables revealed significant associations between chronological age, gender, hours employed, and adjustment to college. Lastly, hierarchical multiple regression analysis revealed disengagement coping accounting for as much as 53% of the variance in adjustment scores. This result suggested disengagement coping adding significant predictive utility for adaptation-associated college adjustment. In light of these findings, counseling professionals may wish to consider the beneficial role of engagement coping in promoting optimal adjustment to college for lower-division undergraduate students with disabilities.

  Citation × Citation Citation Abstract Copy Title: Optimal irrigation management : a framework, model, and application for optimizing irrigation when supplies are limited Author: Hillyer, Charles C. (Charles Carter) Many regions in North America are experiencing water shortages, and these conditions are expected to worsen. The next generation of irrigation scheduling applications must therefore be capable of providing operational advice in support of deficit irrigation strategies. However, the theoretical, technical, and practical challenges associated with deficit irrigation scheduling are far more complex than conventional (full) irrigation. This dissertation presents three distinct systems for addressing the analytical challenges of deficit irrigation management. The first section of the dissertation presents a simulation framework for agro-ecological simulation. The objective was to develop a method to enable the assembly of simulation models from previously and independently developed component models. Based on a requirements analysis of existing simulation models we developed the ModCom simulation framework. ModCom provides a set of interface specifications that describe components in a simulation. ModCom also provides implementations of the core simulation services. The framework interfaces use well-defined binary standards and allows developers to implement the interfaces using a broad range of computer languages. The Second section describes the Irrigation Efficiency Model (IEM). IEM explicitly analyzes irrigation efficiency, accounts for spatial variability of soil properties and irrigation uniformity, performs simultaneous scheduling for all fields in the farm, accounts for energy use and its associated costs, and uses both ET and soil moisture measurements to enhance the accuracy of the irrigation schedules. IEM was developed specifically for implementing Deficit Irrigation and therefore includes analyses that go beyond the requirements of conventional irrigation scheduling. The third section describes Irrigation Management Online (IMO), a web application for optimum irrigation management. This system uses IEM to generate and deliver irrigation scheduling recommendations. IMO has been developed specifically to support irrigation management when either water supplies or delivery system capacities are limited. To mitigate the complexities of irrigation constraints the system has been designed so that the irrigation manager is an integral part of the irrigation optimization procedure. The final section outlines some of the key challenges that the next generation of schedulers must overcome in order to meet the needs of agricultural irrigation in an increasingly water short future. In addition, this section will discuss how irrigation advisory programs will need to operate differently in terms of what they do and how they do it.

  Citation × Citation Citation Abstract Copy Title: Vertebrates, arthropods, and invasive plants : an investigation of the top-down and bottom-up interactions of multiple herbivore guilds in a grassland system Author: Farrell, Kelly Anne Humans are increasing the scale and frequency of many natural disturbances, as well as adding novel disturbances to ecosystems. This thesis uses the arthropod community as a metric to examine the multi-trophic responses to disturbances in California grasslands. Chapter 2 explores how the long-term exclusion of native vertebrate herbivores has impacted arthropod community and trophic structure at Hastings Natural History Reserve. Chapter 3 investigates the impacts of grazing and invasive plants on the arthropod community in a manipulative plant provenance x grazing experiment that had been in place for two years at the Sierra Foothills Research and Extension Center. Few long-term studies have explored the interactions between vertebrate herbivore guilds and the arthropod community. We studied the long-term impact on arthropod community structure and composition of removing vertebrate herbivores from a California oak savannah. We used paired plots to sample arthropods and plant communities inside and outside 11 long-term vertebrate exclosures. We found that arthropods respond to vertebrate access mainly via plant compositional shifts, but that different groups of vertebrates cause changes via different pathways. Large herbivores, including deer, caused a shift from native perennial to exotic annual plants which increased plant nutritional content and supported more herbivore and detritivore arthropods. Burrowing vertebrates such as gophers reduced the predatory arthropod community by reducing vegetation structure, releasing other arthropod groups and resulting in an overall increase in arthropod abundance. These results highlight that alterations to different parts of the vertebrate community can have qualitatively different effects on arthropod community structure. The invasion and spread of non-native plants and the prevalence of livestock grazing are two human-induced disturbances that can have widespread ecosystem impacts. We used a manipulative study to examine how the replacement of native perennial grasses by exotic annual grasses and the introduction of heavy cattle grazing impact arthropod community structure. Arthropod richness, diversity, and abundance did not vary predictably between native perennial and exotic annual grass communities, though arthropods responded to plant community characteristics. In the presence of grazing, arthropod biovolume increased in annual grass treatments, which could trigger a positive-feedback cycle with vector-transmitted plant pathogens to further increase the prevalence of non-native annual grasses. Arthropod community was strongly impacted by cattle grazing, which decreased the biovolume of predatory arthropods, causing a top-down increase in herbivorous arthropod biovolume. Grazing thus impacts plant composition both through the direct removal of biomass and increased plant species evenness, and through arthropod-mediated impacts. Together, these studies show that human alterations of different vertebrate guilds can impact the trophic structure of the arthropod community. Because arthropods mediate a number of ecosystem services, disturbances that alter arthropod assemblages can have far-reaching ecosystem impacts. By exploring the mechanisms by which manipulations of the vertebrate guild alter arthropod community, this thesis demonstrates the importance of horizontal and vertical diversity in multi-trophic interactions.

  Citation × Citation Citation Abstract Copy Title: Ecology of the northern subpopulation of northern anchovy (Engraulis mordax) in the California Current large marine ecosystem Author: Litz, Marisa N. C. Northern anchovy (Engraulis mordax) are a dominant forage fish in the California Current large marine ecosystem (CCLME). However, little is known about northern anchovy abundance, distribution, age structure, or population fluctuations relative to ocean conditions in the eastern boundary upwelling system off the U.S. West Coast. This thesis includes three primary studies of northern anchovy in the CCLME off Oregon and Washington using data collected during four National Marine Fisheries Service (NMFS) surveys (1977-2006): inter- and intra-annual variation in anchovy distribution and its relationship to oceanography, growth rates of larval and juvenile anchovy that indicate the timing of major spawning events and changes in mortality rates, and analysis of whole lipids and fatty acid profiles to determine food sources in years of contrasting oceanographic conditions. First, I quantified the relationship between northern anchovy abundance with environmental variables at two spatial and temporal scales: 1) mesoscale, including sea surface temperature (SST), salinity (SSS), density (SSD), chlorophyll a, distance from shore, and depth; and 2) macroscale, including Pacific Decadal Oscillation Index, Multivariate El Niño Southern Oscillation Index, timing of the Spring Transition, and abundance of cold-water zooplankton. Anchovy densities increased significantly from 1999-2004, and decreased significantly from 2005-2006. SST and proximity to shore were the most consistent parameters explaining anchovy distribution. Year-class strength was highly correlated with, and presumably driven by, the abundance of cold-water copepods. Second, I characterized recruitment for northern anchovy by conducting microstructure analysis of saggital otoliths from late larval and juvenile life history phases collected in September 2006. I identified a protracted spawning period for northern anchovy ranging from June-August 2006. Juveniles that were spawned and hatched early in the summer 2006 had higher growth rates, but smaller back-calculated sizes-at-age during the larval phase, when compared to congeners spawned later that summer. Finally, I determined total lipid content and fatty acid signatures of northern anchovy and three other forage fish species during two contrasting periods of oceanographic conditions (summers of 2005 and 2006): Pacific sardine (Sardinops sagax), Pacific herring (Clupea harengus pallasii), and whitebait smelt (Allosmerus elongatus). Forage fish lipid levels were lowest in 2005 and increased in 2006. Fatty acid biomarkers in 2005 indicated that the food web was based mainly on dinoflagellates, corroborating observations of delayed coastal upwelling and low primary productivity in the CCLME. In 2006, fatty acids reflected higher levels of diatom feeding and zooplankton carnivory. The results of these studies confirm that in the CCLME, northern anchovy are sensitive to even small environmental perturbations, which is important because this work provides metrics for evaluating climate-mediated, bottom-up ecological processes affecting anchovy survival.

A rigorous program of ecosystem restoration can protect and enhance wetland plants, animals, and services (Pywell and Putwain 1996). The restoration projects of the West Eugene Wetlands Program (WEWP) comprise one of the few large-scale and long-term integrated restoration programs in the world. Successful ecosystem restoration requires establishing and maintaining native plants. In turn, plant establishment hinges on having suitable environmental conditions, using species with adequate germination and growth rates, and reducing competitive pressure from non-native plants (Figure 1). In year one of this project, we synthesized the wealth of plant establishment data during wetland restoration in the West Eugene Wetlands Program (Wilson 2004). In year two, our objectives were to expand on these results in several important ways: • Generalize these results through the investigation of plant traits (Table 1) that consistently correspond to the patterns of establishment and vigor (Figure 1). • Systematically compile the results into a trait database. This database includes findings from similar ecosystems, both in the Willamette Valley and elsewhere. • Testing the effect of habitat variation on the relationship between traits and seedling establishment patterns. Our goal is to predict key aspects of prairie restoration performance, in this case establishment rates, based on species traits and habitat. These predictions can then be applied as management recommendations, such as which species to sow to maximize native plant abundance at a given site, even if the species have not been field tested. The two components of our project–plant traits and the database–are crucial to this goal. • Without the generalization that traits allow, understanding of wetland restoration increases slowly and expensively, one case study at a time. • The organization of the database will increase the power and efficiency of revealing the relationships between plant traits and plant performance. Perhaps even more important is the role of the database in developing a Web-based expert system for managers wishing to plan wetland restorations.
