The study is published in <i>Scientific Reports<\/i>.<\/p>\n<section class=\"article-banner first-banner ads-336x280\">\n         <!-- \/4988204\/Phys_Story_InText_Box --><\/p>\n<\/section>\n<p>As with other dolphin species, common bottlenose dolphins (Tursiops truncatus) communicate using a range of whistles, including a &#8216;signature whistle&#8217; which is unique to each animal. Previous research has indicated that different groups of dolphins tend to develop different styles of signature whistles. It is, however, unclear which factors influence the development of signature whistles and these different styles.<\/p>\n<p>Using 188 hours of recorded acoustic data, Gabriella La Manna and colleagues analyzed the differences in signature whistles between six geographically distinct populations of common bottlenose dolphins across the Mediterranean Sea. The sites included Port Cros in the French Riviera, Alghero in the Sardinian Sea, and Ostia-Fiumicino in the Tyrrhenian Sea (all considered the western Mediterranean region); Cres-Losinj in the Adriatic Sea and the Gulf of Corinth in the Ionian Sea (both considered eastern); and Lampedusa in the Strait of Sicily (considered southern). There is established genetic variation between eastern and western dolphin populations. The authors identified 168 individual signature whistles and m<a href=\"https:\/\/buradabiliyorum.com\/en\/category\/download-scripts-themes-apps\/\" data-internallinksmanager029f6b8e52c=\"9\" title=\"Download Scripts &amp; Themes &amp; Apps\" target=\"_blank\" rel=\"noopener\">app<\/a>ed variations in acoustic features such as duration and changes in pitch.<\/p>\n<p>The authors analyzed the influence of region (a proxy for genetic variation), geographic site, the local ocean environment (such as whether the sea bottom was muddy or covered in seagrass), and population demographics had on differences between signature whistles. They report that the local ocean environment and population most strongly influenced signature whistle variation. For example, signature whistles in areas with seagrass, such as Lampedusa and Port Cros, were higher pitched and shorter in length compared to when the sea bottom was muddy. In small populations, such as in the Gulf of Corinth, signature whistles had more changes in pitch than among larger populations.<\/p>\n<p>In contrast, region\u2014and therefore genetic variation\u2014had no strong influence on whistles. The authors suggest that these findings support the &#8216;acoustic adaptation hypothesis&#8217; and that bottlenose dolphins develop signature whistles best suited to their local habitat.<\/p>\n<hr\/>\n<div class=\"article-main__explore my-4 d-print-none\">\n<p>                                            Tuning into dolphin chatter could boost conservation efforts\n                                        <\/p><\/div>\n<hr class=\"mb-4\"\/>\n<div class=\"article-main__more p-4\">\n                                                                                                <strong>More information:<\/strong><br \/>\n                                                Gabriella La Manna, Determinants of variability in signature whistles of the Mediterranean common bottlenose dolphin, <i>Scientific Reports<\/i> (2022).  <a rel=\"nofollow noopener\" target=\"_blank\" data-doi=\"1\" href=\"https:\/\/dx.doi.org\/10.1038\/s41598-022-10920-7\">DOI: 10.1038\/s41598-022-10920-7<\/a>. <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.nature.com\/articles\/s41598-022-10920-7\">www.nature.com\/articles\/s41598-022-10920-7<\/a><\/p><\/div>\n<p>                                        <!-- print only --><\/p>\n<div class=\"d-none d-print-block\">\n<p>                                                 <strong>Citation<\/strong>:<br \/>\n                                                 Local environment and population demographics, not genetics, influence bottlenose dolphin &#8216;names&#8217; (2022, May 26)<br \/>\n                                                 retrieved 26 May 2022<br \/>\n                                                 from https:\/\/phys.org\/<a href=\"https:\/\/buradabiliyorum.com\/en\/category\/news\/\" data-internallinksmanager029f6b8e52c=\"2\" title=\"News\" target=\"_blank\" rel=\"noopener\">news<\/a>\/2022-05-local-environment-population-demographics-genetics.html<\/p>\n<p>                                            This document is subject to copyright.
