Joe Roman, in Trends in Ecology & Evolution, 2023 Great whale conveyor belt Many great whales are capital breeders, migrating from high-latitude, nutrient-rich feeding grounds where they spend the summer to low-latitude, nutrient-poor breeding grounds where they spend the winter (Figure 1B) [...
It has been estimated that a single humpback whale returning to Tonga every year could generate US$1 million in whale-watching revenue over the course of its 45-year lifetime, leaving little doubt that a live whale is considerably more valuable than a dead one. Mothers and their calves The...
We have five ongoing research programs including a photo-identification survey commenced in 1992 to provide data for the study of the behaviour, social dynamics and ecology of the eastern Australian humpback whales. Our behavioural data and photo-id fluke catalogue have already made a significant con...
CThey made notes of its behaviour. DThey recorded the sounds it made. EThey took a picture. Show workspace Questions 7-8 The passage mentions places the whale may have passed close to on its journey. WhichTWOplaces may the whale have passed?
Humpback whale vocal behaviour also varies throughout the annual cycle. Humpback whale song is produced primarily by males49,50,51and is mainly associated with reproductive behavior at low latitudes, although song also occurs regularly on foraging grounds51,52,53. Song consists of a rhythmic, repea...
Humpback whalesongs comprise units that are the shortest audible sounds. A series of units make up a phrase. A series of words make up a theme, and finally, a series of themes make up the song. One song can last up to 30 minutes and may be repeated for up to 24 hours. ...

Helena Bay and Dassen Island, and farther south to Cape Town. The scientists also found it difficult to estimate the number of animals due to the large number of individuals that were hidden under the water’s surface. Overall, the scientists assumed that it was a “new” behaviour of the...
