Acoustic monitoring of golden jackals in Europe: setting the frame for future analyses

摘要: AbstractThe golden jackal (Canis aureus) utters complex howls that can be used to monitor their population density and distribution in a specific area. However, little is known of the vocal behaviour this species. In present paper, we show first results acoustic analysis followed monitoring Friuli–Venezia Giulia during 2011–2013. We estimated number callers by screening fundamental frequency emissions within howl. analysed 42 vocalizations given single or multiple individuals. The howling duration significantly increased with emitters, which ranged between one three our estimates. Twenty-nine were then submitted quantitative semi-automatic procedure based on dynamic time warping. Based resulting dissimilarity indices, clustered six different acoustically uniform groups, showed potential for these procedures developed into futur...
