The spread of urbanization leads to habitat fragmentation and deterioration and changes the composition of ecosystems for species all over the world. Different groups of organisms are impacted differently, and insects have experienced loss in diversity and abundance due to changing environmental factors. Here, I collected seed beetles across 12 urban and rural sites in Phoenix, Arizona, to analyze the effects of urbanization and habitat variation on beetle diversity and abundance. I found that urbanization, host tree origin, and environmental factors such as tree diversity and density had no impact on overall beetle diversity and abundance. Beetles were found to have higher density on hosts with a higher density of pods. In assessing individual beetle species, some beetles exhibited higher density in rural sites with native trees, and some were found more commonly on nonnative tree species. The observed differences in beetle density demonstrate the range of effects urbanization and environmental features can have on insect species. By studying ecosystem interactions alongside changing environments, we can better predict the role urbanization and human development can have on different organisms.

ABSTRACT



Although it is generally acknowledged that a college degree is foundational to achieving success in the 21st century, only 19.5% of those entering public community colleges graduate with an associate's degree within three years (NCES, 2014). Many challenges have impeded students including being underprepared to transition from high school to college, being a first-generation college student, and having limited support networks.

The purpose of this action research project was to implement a college-going readiness program designed to increase the social and personal readiness of high school students making the transition from high school to college. The College Transition Project, the intervention, offered a series of face-to-face class sessions for students and online supplemental materials for students and parents (a) guiding and assisting students in navigating the college system, (b) improving social readiness, and (c) increasing goal setting, time management, communication, and stress management. The curriculum was designed to include key topics including potential pitfalls or challenges common to previously unsuccessful college students. Goal orientation, co-regulation, and self-regulation theories provided frameworks supporting the intervention. Over a five-week period, an instructor taught students who received information on these topics; while students and parents could review online resources at any time.

A concurrent mixed methods research design was employed and data included pre- and post-intervention surveys, field notes, and post-intervention interviews. Results indicated some modest outcomes were attained. Quantitative results indicated no changes in various study measures. By comparison, qualitative data showed students: recognized the usefulness of co-regulation as it related to college preparedness, realized self-regulation efforts would aid their transition to college, and developed some college navigation skills that would facilitate transition to college. Most students acknowledged the need to identify goals, engage in self-regulation, and practice self-efficacy as critical components for students transitioning from high school to college. The discussion explained the outcomes in terms of the theoretical frameworks. Implications focused on additional ways to develop self-efficacy and employ co-regulated activities and relationship building to aid in developing motivation and to nurture emerging identities in students who were transitioning from high school to college.
