The researchers looked at data from Wisconsin and said that wolves reduce deer populations and also scare deer away from linear landscape features, including roads, that wolves often prowl.

The research was published Monday in the journal Proceedings of the National Academy of Sciences.

A prior study found that deer-auto collisions cost more than $8 billion annually in the United States.
