Summary: | Wolves (Canis lupus) population management is a priority for conservationists, wildlife managers, hunters, trappers, cattle producers, and First Nations. Ideally, a survey technique should allow individual identification to increase managers’ ability to precisely and accurately estimate population trends in abundance, distribution, density and pack structure. However, wolf monitoring is notoriously difficult because of the species’ low density and elusive nature. Furthermore, lowering operating costs is a priority for wildlife agencies. In some cases, non-invasive survey techniques have lower monitoring costs relative to more invasive approaches like capture and tagging. There have been very promising developments in bioacoustics that could answer these questions. Morphological differences in the vocal tract of wolves mean that individuals have measurably distinct vocalizations. Minimum counts, age class, and individual identification have been achieved in previous studies, yet these methods remain to be ... |
