Seed Beetle Abundance and Diversity in Urban and Rural Sites

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.

The importance of mobility and psychological attitude during hospitalization and how they correlate with recovery is highlighted in this paper through a review of the research literature on both topics. The literature review revealed that increased mobility and positive psychological cognitive state are correlated positively with increased recovery among hospitalized individuals. The research findings have led to the development of child mobility apparatuses called "Lily Pads" being constructed and donated to pediatric hospitals with the intention of helping increase patient mobility and positivity in pediatric wards of hospitals. A history of the lily pads and their potentially positive impact is presented as well as a brief description of the construction process, should readers like to build and donate these apparatuses to their local hospital. It is concluded that further empirical research on the use and effects of lily pads in pediatric wards and the possible correlation with pediatric recovery is needed in order to qualitatively and quantitatively assess the apparatuses' effectiveness.
