Dear MARMAM members, I am happy to share the exciting data we are bringing in our lattes publication for MMS journal:Gonçalves, M.I., Djokic, D., Baumgarten, J., Marcondes, M.C.C., Padovese, L.R., Eugênio, L.D.S., Sousa-Lima, R. Abrupt change in humpback whale song from Brazil suggests cultural revolutions may occur in the South Atlantic. Marine Mammal Science, 2023. - DOI: - 10.1111/mms.13093
https://www.researchgate.net/publication/376072322_Abrupt_change_in_humpback_song_from_Brazil_suggests_cultural_revolutions_may_occur_in_the_South_Atlantic Five decades after the first description of the humpback whale song in the Northern Hemisphere, and two decades after the first description of a cultural revolution in the eastern Australian population, this Note provides evidence of an abrupt change (leastways) of the song occurred in 2018 season, in breeding stock A. This intense song change measured by simplified Levenshtein distance implies cultural revolutions could be happening in the Atlantic ocean as well, further stressing the possibility of Southern Hemisphere Cultural Exchange (SHCE) phenomenon.This work also revisited standard definitions of humpback whale song, its structure, culture and common methodology.
