Dear colleagues, We are delighted to share with you our latest scientific publication on the acoustic behaviour of wild bottlenose dolphins: Mosca, O., Methion, S., & Diaz Lopez, B. (2025). Whistle rate determinants in wild bottlenose dolphins: behaviour, location, and group size. Bioacoustics, 1–20. https://doi.org/10.1080/09524622.2025.2482918 This study investigates the key factors influencing whistle production in free-ranging Tursiops truncatus, based on over 15 years of data collection and 189 hours of acoustic recordings in the Mediterranean and Atlantic waters. A limited number of copies of the article are available online at this link: <https://www.tandfonline.com/eprint/3SJZTHBQMRGMAMKWGFBZ/full?target=10.1080%2F09524622.2025.2482918&fbclid=IwY2xjawJjttpleHRuA2FlbQIxMQABHvX4iQ7Q33u5KBSz6TE_q2Ngkj93V6_Ur70zrl7qQeDURNuRsGZmziEDjB-j_aem_ROZPxMLZAh4nSRVviA7vKA> We hope this contribution will be of interest to those working on marine mammal behaviour, bioacoustics, and animal communication.
