Description
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.

Description
Oral health is influenced by many factors, including diet (Alpert, 2017). However, the assumption arises that unique and ever-changing diets have varying effects on oral health. This project aimed to determine the effect of the Punjabi diet on oral health. Specific goals included understanding components of a general Punjabi diet, as well as the current oral health status for individuals of the Punjabi community, to ultimately determine the correlations between the two variables. It was hypothesized that a diet consisting of foods primarily under the Punjabi diet would have fewer oral health concerns because healthier food items would be consumed. By researching relevant background information to create appropriate survey questions, survey questionnaires were sent to members of the Punjabi population (not just limited to the Punjab geographical region) for completion. From this data, analysis depicts that there is no relationship between the oral health of individuals with the diet they consumed, thus rejecting the initial hypothesis. Similarly, a lack of a relationship was found between the oral health of individuals and their respective oral hygiene habits. These results suggest that the current Punjabi diet may not be as healthy as initially assumed and that there are likely other factors that influence an individual’s oral health, such as genetics, environmental factors such as stress (Kapila, 2021), or other unexplored dietary variables, such as diets high in sugar.
