Fig S7. Hierarchical plot of humpback whale song sequences

Fig S7 The dissimilarity dendrograms show the song sequences which were delineated directly from the observed sound files for each period. Only sequences with a minimum of 4 different themes were included. The sequences connected with branches of the same color within each dendrogram represent a cluster of sequences which had a minimum of 40% similarity according to hierarchical clustering based on the Levensthein Similarity Index (LSI)
