      Researchers are installing dozens of "bear detectors" in Rhode Island as they study movements of black bears living in the state.

      Scientists at the University of Rhode Island and the Rhode Island Department of Environmental Management are conducting the study. They're setting up the 42 bear detectors in the western part of the state to collect fur that can be analyzed for its DNA.

      Once they have that, they can identify individual bears and use that information as they work to determine how many bears are living in Rhode Island, the corridors they travel along and other information.

      URI says that scientists believe black bears were wiped out in Rhode Island during Colonial times, but in recent years, the bear populations in neighboring states have increased.
