Matrix of song similarity calculated using the The Levenstein Similarity Index and the Dice's Similarity Index analyses from Culturally transmitted song exchange between humpback whales (Megaptera novaeangliae) in the southeast Atlantic and southwest Indian Ocean basins

Table S3. The Levenstein Similarity Index (LSI) (White area of matrix) and the Dice's Similarity Index analysis (Grey shaded area of matrix) for all singers in each population and year. The measure of self-similarity (i.e., how similar all songs an individual sings are) is present on the diagonal of the resultant LSI theme similarity matrix.
