UW-Madison study finds wolves can bring benefits to ecosystem, but are not a 'cure all'

A new study by a University of Wisconsin-Madison team of researchers looking at wolves on an island in Lake Superior is helping shed light on the role that certain species play in helping shape an entire ecosystem.

The conclusion was those species do play a role, but those effects may be temporary, and humans also play a role.

The real story, though, was the process of reaching that conclusion.
