My Research, In a Snail Shell

This summer, I have been working on a Summer Team Impact Project at the Potomac Science Center in Woodbridge, Virginia. I have been studying an invasive species of snails―termed mystery snails―and by collecting samples of these invaders and their native counterparts, I aim to learn more about the mystery snails as a whole, as well as how their parasitology differs from that of the snails that are native to this region. This research is important because both invasive species and parasites threaten the biodiversity of an ecosystem, and biodiversity is important for ensuring that the ecosystem can withstand stressors and catastrophic events that would otherwise destabilize the ecological balance. The overarching project is focused on aquatic communities as bioindicators of change, and although the other members of my team specifically focus on the Potomac River for their research, I also sample from other rivers in the Northern Virginia area.

It’s been very exciting to take part in research that allows me to experience lab-based research as well as fieldwork. The amount that I’ve learned in both settings is unreal (pro-tip: it’s a lot easier to find and collect snails at low tide), and the following picture was taken of me while collecting snails from a site on the Rappahannock for the second time, as we could hardly find anything the first time around.
