  Citation × Citation Citation Abstract Copy Title: Exploring stakeholders' attitudes and beliefs regarding behaviors that prevent the spread of invasive species : a focus group study Author: Kubeck, Gwenn This research explores the barriers that prevent stakeholders from changing their hobby behaviors to help prevent the spread of invasive species in Oregon. Invasive species are increasingly causing economic and ecosystem harm in Oregon. This is among the first studies done on the human dimensions of invasive species. Using the Theory of Planned Behavior as a framework, the attitudes, norms and perceived behavioral controls regarding preventative behaviors were elucidated during four focus groups (29 individuals) with individual groupings of gardeners, anglers, hunters and boaters. Findings indicate six belief barriers to changing hobby behaviors. These include 1) the attitude that preventative behaviors, such as using pesticides, may be worse for the environment than invasive species, 2)the attitude that the fight against invasive species is a losing battle, 3)the norm belief that institutions don’t care enough to prioritize action on the issue of invasive species, 4) the norm belief that the general public both doesn’t know and doesn't care about invasive species, 5) the behavioral control belief that one doesn't know enough about the preventative behaviors to be effective, and 6) the behavioral control belief that preventative behaviors are too difficult to perform. Understanding the beliefs that prevent changes in behavior will help inform the creation of effective statewide invasive species awareness and actions campaigns, such as that being led by the Oregon Invasive Species Council, as well as provide a foundation of research on which to build additional research. Findings suggest that an effective way to engage stakeholders in being part of the solution to invasive species may include addressing social norms by targeting awareness messaging and engagement activities to hobby groups.

  Citation × Citation Citation Abstract Copy Title: Exploring the Perspectives and Behaviors of Teachers on Invasive Species Author: Root, Skye This study explores the role of classroom use of live organisms as a pathway for the spread of invasive species. The overall guiding research question is “Are behavioral changes necessary to reduce the spread from the classroom pathway?” Using focus groups comprised of key educators, this study seeks to identify attitudes, norms, and barriers to inform the development of solutions to mitigate the spread of aquatic invasive species from the classroom. A modified version of the Theory of Planned Behavior is used to tabulate values, knowledge, concerns, and solutions that could lead to behavioral change. A total of 65 educators participated in six different focus groups, with nearly half of the participants elementary teachers. Findings indicate strong educational, use-related, and ethical values deeply rooted in having, and continuing to have, live organisms in the classroom. Information about invasive species, however, is not perceived as readily available, and credible sources are often difficult to discern by participants who are mainly searching online for needed information. Logistical concerns, euthanization practices, ecological damages, and children’s outdoor experiences are described as potential barriers to behavior change, and educational liaisons, outreach activities, and policy changes are suggested solutions intended to change behavior. Using the Theory of Planned Behavior as a foundational theory and Multiple Streams framework as a policy guide, this study recommends five specific actions be taken by policy entrepreneurs: (1) Fund, develop, and maintain an invasive species informational website where educators can go for up-to-date references on sourcing, care and handling, disposal, and species identification. (2) Create example fact sheets for organism suppliers and encourage their adoption by the suppliers. (3) Add invasive species educational standards on a national scale through the NSTA and NISC, and provide teachers with curriculum suggestions involving the integration of invasive species education into core subject matter. (4) Develop and test an invasive species professional development training seminar for K-12 educators to be applied to large scale science association meetings or local in-service days. (5) Seek funding for the development of invasive species education curriculum that could be implemented through credentialing programs.

  Citation × Citation Citation Abstract Copy Title: Life-history and physiological trade-offs to reproduction of invasive and noninvasive Rubus Author: McDowell, Susan C. The goal of this dissertation was to improve our understanding of the physiology and life-history of invasive plants and of the mechanisms underlying life-history trade-offs. I compared invasive and noninvasive species of Rubus (blackberry) that grow together in the Pacific Northwest. Three hypotheses were investigated: (1) Invasive Rubus have higher photosynthetic capacity and lower leaf-level resource costs of photosynthesis than native, noninvasive species; (2) The physiological effects of reproduction on foliage result in higher reproductive effort for noninvasive Rubus than for an invasive species, in spite of the greater number and size of fruit produced by the invasive species; and (3) Reproduction produces greater trade-offs to growth for noninvasive Rubus because of its higher reproductive effort, and these trade-offs affect the population demographics of these species. I found that two invasive species, R. discolor and R. laciniatus, had higher photosynthetic capacities and maintained these rates for a longer portion of the year than two noninvasive species, R. ursinus and R. leucodermis. Furthermore, the two invasive species had higher rates of photosynthesis per unit resource investment, such as carbon, nitrogen, and water, than the noninvasive Rubus. I found that these photosynthetic characteristics could be used to distinguish between the noninvasive and invasive species using discriminant analysis. I compared reproductive effort for one of the invasive, R. discolor, and one of the noninvasive, R. ursinus, species. I found that, although the invasive Rubus allocated more resources directly to reproduction than the noninvasive species, it had lower reproductive effort because it did not have the significant decline in leaf nitrogen and photosynthetic capacity and significant increase in mid-day water stress that were associated with reproduction in the noninvasive species. I also observed that sexual reproduction in the noninvasive species was associated with trade-offs to growth both within and between generations, but these were not observed in the invasive species. These trade-offs in the noninvasive species resulted in an almost complete dependence on clonal growth rather than sexual reproduction for population growth. The invasive Rubus relied on sexual reproduction for population growth relatively more than the noninvasive species and, therefore, reproductive effort influenced the demographics of these species.
