Wild wolves play an essential ecological role, so researchers must be able to track them accurately. Unfortunately, because wolves travel over wide ranges, tracking them visually is very difficult. The ability to use sound to identify wolves would make wolf surveys much more reliable. PhD student Holly Root-Gutteridge and her team at Nottingham Trent University have developed software that enables them to identify individual wild wolves by their howls. The research appears in the journal Bioacoustics.
