With the rise of cars and other motorized vehicles has come the rise of air pollution, which tends to have disproportionate environmental and health impacts on low-income and communities of color. This study analyzes car presence and air quality on a transect within Gettysburg, PA to determine if there is a relationship between air pollution and vehicle presence, and if there is a difference in air quality between higher price bracket housing compared to campus, commercial, and lower price bracket housing. To test our research questions, we identified nine sampling locations along a transect where we measured air pollutants, including …

Human-caused climate change creates a positive feedback loop that emits more carbon dioxide into the atmosphere instead of being sequestered in the Earth or its oceans. A major contributor to this feedback loop is deforestation in order to use land for agriculture and livestock. This study aims to investigate differences in carbon sequestration capabilities of forests, pastures, and cropland through soil and tree sampling in Gettysburg, Pennsylvania. The main hypothesis of this study is that forested land will be the most effective at carbon sequestration. The loss on ignition method (LOI) was used to determine the percent organic material in …
Individual-Level Responses To Rapid Climate Change In Common Terns (Sterna Hirundo) And Arctic Terns (Sterna Paradisaea), Kaiulani A. Sund

This study examines fine-scale environmental changes and intraspecific variation in the diet and foraging behavior of two seabirds in the Gulf of Maine, one of the fastest-warming regions of the ocean. This variation on the individual level, or behavioral plasticity, may help long-lived species to persist in rapidly changing environments. As the water warms, seabirds’ preferred prey (hake and herring) follow cooler waters deeper and farther offshore. It is unlikely that all individuals respond to changing food availability in the same way. For common terns (Sterna hirundo) and Arctic terns (Sterna paradisaea) breeding on Petit Manan …
