Biology major Polina Kourova '27 spent her summer as a 2025 Eckley Scholar studying the feeding habits of the Brachionus manjavacas rotifer.
“Rotifers are marine invertebrates that play a crucial role in aquatic ecosystems around the world. They typically consume algae and bacteria of a particular size, but in nature they are exposed to particles of different shapes and sizes, which may impact their capture and ingestion rates,”
said Kourova. These microscopic creatures are among the first consumers of lake algae and bacteria in the food chain. Kourova said studying feeding patterns on this base level can help biologists better understand these animals and their impacts on the environment.
