Due to a number of selective pressures acting on signals, the contribution of genetic drift is often complex to outline. This study aims at evaluating if an examination of the acoustic structure of communication signals can allow the identification of evolutionary units in species capable of vocal learning. We quantified and compared parameters of whistles emitted by three dolphin species (Stenella coeruleoalba, Delphinus delphis, and Tursiops truncatus) to examine the hypothesis that acoustic signals permit the recognition of differentiation between populations from the Atlantic Ocean and the Mediterranean Sea. In the three species, recordings were correctly assigned to their basin of origin with a percentage higher than 82% by DFA. Frequency parameters were the most stable within each species. Where gene flow has been shown, i.e., within Atlantic Ocean, significant differences were found principally in modulation parameters. We hypothesize that these parameters are influenced by social and behavioral factors and that similar ecological conditions led to convergent acoustic features. Results of this study suggest that is it possible to recognize evolutionary units based on acoustic data.<\/jats:p>","DOI":"10.1121\/1.4877334","type":"journal-article","created":{"date-parts":[[2014,5,21]],"date-time":"2014-05-21T00:35:08Z","timestamp":1400632508000},"page":"2241-2241","update-policy":"http:\/\/dx.doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":1,"title":["The acoustic structure of whistles as a tool for identifying evolutionary units in dolphins"],"prefix":"10.1121","volume":"135","author":[{"given":"Elena","family":"Papale","sequence":"first","affiliation":[{"name":"Dept. of Life Sci. and Systems Biology, Univ. of Torino, via accademia albertina 13, Torino 10123, Italy, elena.papale@unito.it"}]},{"given":"Marta","family":"Azzolin","sequence":"additional","affiliation":[{"name":"Dept. of Life Sci. and Systems Biology, Univ. of Torino, via accademia albertina 13, Torino 10123, Italy, elena.papale@unito.it"}]},{"given":"Irma","family":"Cascao","sequence":"additional","affiliation":[{"name":"Centro do Instituto do Mar (IMAR) da Universidade dos A\u00e7ores, Departamento de Oceanografia e Pescas, Universidade dos A\u00e7ores, Horta, Portugal"}]},{"given":"Alexandre","family":"Gannier","sequence":"additional","affiliation":[{"name":"Groupe de Recherche sur les C\u00e9tac\u00e9s, Groupe de Recherche sur les C\u00e9tac\u00e9s, Antibes, France"}]},{"given":"Marc O.","family":"Lammers","sequence":"additional","affiliation":[{"name":"Hawaii Inst. of Marine Biology, Univ. of Hawaii, Kanehone, HI"}]},{"given":"Julie N.","family":"Oswald","sequence":"additional","affiliation":[{"name":"Bio-Waves, Bio-Waves, Encinitas, CA"}]},{"given":"Monica","family":"Perez-Gil","sequence":"additional","affiliation":[{"name":"Society for the Study of Cetaceans in the Canary Archipelago, Puerto Calero, Spain"}]},{"given":"Monica","family":"Silva","sequence":"additional","affiliation":[{"name":"Centro do Instituto do Mar (IMAR) da Universidade dos A\u00e7ores, Departamento de Oceanografia e Pescas, Universidade dos A\u00e7ores, Horta, Portugal"}]},{"given":"Cristina","family":"Giacoma","sequence":"additional","affiliation":[{"name":"Dept. of LIfe Sci. and Systems Biology, Univ. of Torino, Torino, Italy"}]}],"member":"231","container-title":["The Journal of the Acoustical Society of America"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/pubs.aip.org\/jasa\/article\/135\/4_Supplement\/2241\/610564\/The-acoustic-structure-of-whistles-as-a-tool-for","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/pubs.aip.org\/jasa\/article\/135\/4_Supplement\/2241\/610564\/The-acoustic-structure-of-whistles-as-a-tool-for","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,7,17]],"date-time":"2023-07-17T06:59:02Z","timestamp":1689577142000},"score":1,"resource":{"primary":{"URL":"https:\/\/pubs.aip.org\/jasa\/article\/135\/4_Supplement\/2241\/610564\/The-acoustic-structure-of-whistles-as-a-tool-for"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014,4,1]]},"references-count":0,"journal-issue":{"issue":"4_Supplement","published-print":{"date-parts":[[2014,4,1]]}},"URL":"https:\/\/doi.org\/10.1121\/1.4877334","relation":{},"ISSN":["0001-4966","1520-8524"],"issn-type":[{"value":"0001-4966","type":"print"},{"value":"1520-8524","type":"electronic"}],"subject":[],"published-other":{"date-parts":[[2014,4]]},"published":{"date-parts":[[2014,4,1]]}}}
