INHS Malacologists Sarah Bales, Josh Sherwood and Amy Stultz were featured in an article in the Rockford Register Star. The team is one of three teams conducting statewide mussel surveys, documenting the location, size, age, sex and species of mussels they find. Mussels are an important part of the ecosystem, filtering pollutants, providing shelter to small organisms, as well as food for larger organisms such as raccoons and muskrats. By understanding the mussel populations in a location, biologists are better able to determine the health of that river.
