Three brilliant people and me ... all the world's a stage, and a beginning 🤣This was a lot of fun, recommend sharing a stage with any of these folks - thanks @nakedprimate.bsky.social for the invite!

![Comparison of our results (filled circles) with known or probable dialect group detections (colours) in previous Mediterranean sperm whale research (other symbols) [31–36,61]. Note that for other papers, assigned dialect groups represent our best guess based on the available information, but should not be regarded as definitive without further quantitative analyses. See the electronic supplementary material, table S6 for additional details on past work and our rationale for dialect group assignments of previous studies.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:hhvkb7rma4umjudsoxhwuwhk/bafkreihomot3vxdgppzrdcmkxhubmui5odzgystiirkb52z3mye6ej6gn4)
![Representation of Mediterranean coda repertoires showing two detected dialect groups and their corresponding identity coda types. Top: average linkage hierarchical clustering dendrogram shows similarity among sperm whale coda repertoires recorded in two locations in the Mediterranean Sea. Repertoires that are more similar in terms of probabilistic coda type usage cluster closer together and have a higher correlation value (y-axis). The geographical source of each repertoire is listed below the dendrogram (red B, Balearic Islands; blue H, Hellenic Trench). This tree was constructed in IDcall using critfact = 15 and minrep = 15 (electronic supplementary material, table S3; see [17] for a full description of IDcall parameters). Middle: heat map depicts probabilistic identity coda type usage (rows) for each repertoire (columns). Arbitrary identity coda type labels are on the left and identity coda type centroid rhythm plots, where each dot represents one click and the coda type is coloured by dialect group, are on the right; 47.9% of the codas used to generate the dendrogram are represented in this heat map. Labels beneath show year of recording. Bottom: stacked bar plots show the posterior probabilities of repertoire assignments to dialect groups. Bottom labels show the social unit identity when known and the number of codas in each repertoire in parentheses. Along the Hellenic Trench, known social units include: Antikythira, Bestend, Casper, Chromo, Falasa, Ippolyti, Keri, Kythira, Lakon, Palaio, Pylos, Veneti, Zak, Zakpylos and Zante. If multiple social units were recorded together, their names are appended (e.g. PylosVeneti). If a social unit was recorded with additional unknown whales, the social unit’s name is appended with UNK (e.g. PylosUNK). Note that social unit was unknown (and is left blank) for the Balearic Islands coda repertoires.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:hhvkb7rma4umjudsoxhwuwhk/bafkreifb3taijdd4wsnl7yi2swvucygcwg7vuvhcdji2vnt3k34bdnkyh4)
