A Seasonal Decomposition Comparison Between Forest And Turf Habitats: Implications For Climate Change, Amanda Shirmer
A Seasonal Decomposition Comparison Between Forest And Turf Habitats: Implications For Climate Change, Amanda Shirmer
DePaul Discoveries
Decomposition is an essential ecosystem service in which microorganisms breakdown organic matter. This process improves soil health and acts as a vital step in global carbon cycles. In this study, we examined decomposition rates and associated soil properties in turf and forest habitats across summer and fall seasons in order to determine how land management practices and climate change may be altering local decomposition regimes. Our study determined that there was a statistically significant difference between decomposition rates in turf and forest ecosystems (P=0.003) and a significant difference in decomposition rate across season (P

Environmental Impacts Of Holiday Gift Giving Of Books And Movies, Benjamin Shaffer
DePaul Discoveries
This project examines the relationship between gift giving deadweight loss (when the cost of a gift exceeds it value to the recipient) or welfare gain (when the value of a gift to a recipient exceeds the cost of a gift), and the environmental impact of gifts. Surveys of American adults were used to determine the economic welfare losses or gains created by holiday gift giving, comparing gifts of traditional (paper) books and DVD or Blu-ray format movies. Both products showed overall welfare gains as gifts, with books averaging a larger welfare gain than movies. An ANOVA was done to determine …
