In this Urban Barcoding Project, we will collect moss samples from ecosystems in Tenafly, NJ and New York, New York and compare the biodiversity of the mosses in each region. We will collect 10-15 samples in each place and utilize local parks to collect samples. After we sequence and identify our samples we plan to conduct further research on the different species of moss and their role as bioindicators of air pollution. The goal of this project is to understand the effects of poor air quality on the biodiversity of an ecosystem. As stated earlier, human activity is causing worsening air quality conditions, and biodiversity is negatively impacted by poor air quality. It is essential for the health of ecosystems that biodiversity is maintained.
