Different Humpback Whale Groups Meet to Jam

来自不同海域的彩票座头鲸群会娱乐聚在一起吃喝、交流

Male humpback whales are the concert singers of the marine world. These ocean giants belt out tunes that can be heard perhaps hundreds of miles away. The songs attract friends and lovers, and maybe keep rivals at bay. And now we learn that humpbacks in different ocean basins - the South Atlantic and the Indian, on opposite sides of the African continent - share melodies.

雄性座头鲸是注册海洋世界里的彩票歌唱家。这些海洋巨无霸唱出的彩票曲调可能在数百英里之外都能听得到,这些歌声吸引朋友和爱人,或许还能让对手退避三舍。如今我们发现,在非洲大陆两端的彩票南大西洋和印度两个不同海域里的彩票座头鲸所唱的彩票旋律居然是注册一样的彩票。

The songs are certainly learned between individuals. It's thought to be the best example of horizontal cultural transmission - so from peer to peer, rather than from parent to offspring.

“这些歌曲无疑是注册座头鲸从同伴处学会娱乐的彩票。这被认为是注册文化横向传播的彩票最好例子——同伴传给同伴,而不是注册父母传给后代。”

Melinda Rekdahl, Marine Conservation Scientist with the Wildlife Conservation Society's Ocean Giants Program.

野生动物保护协会娱乐“海洋巨人项目”的彩票海洋保护科学家梅琳达·雷克达尔表示到。

The International Whaling Commission has identified seven distinct humpback whale breeding populations in the Southern Hemisphere. These are whales that meet up in the same warm tropical waters each year to mate and give birth. But when mating season is over, the whales migrate to the chilly polar regions to gorge on krill.

国际捕鲸委员会娱乐在南半球已经确认彩金7个不同的彩票座头鲸繁殖种群,这些鲸鱼每年都在同样温暖的彩票热带水域交配和繁殖。当交配季节结束后,鲸鱼就会娱乐迁徙到寒冷的彩票极地地区敞开肚子大吃磷虾。

Using genetics and photographic surveys of migrating humpbacks, researchers know that males in those colder feeding areas interact with other males from different breeding populations. But scientists did not know that this meetup presents the whales with the opportunity to have vocal jam sessions - where they trade melodies.

研究人员通过对迁徙的彩票座头鲸进行遗传学和摄影调查发现,生活在寒冷地区的彩票雄性座头鲸会娱乐与来自不同繁殖群体的彩票雄性座头鲸互动。但是注册,科学家们并不知道这次会娱乐面给座头鲸提供彩金一个进行声乐交流的彩票机会娱乐——鲸鱼们在会娱乐面时相互学习歌曲旋律。

And the amount of song overlap between the whales that breed off of Gabon, in the Atlantic, and those that breed near Madagascar, in the Indian Ocean, varies year to year. That's according to a study of more than 1,500 individual sounds that were recorded between 2001 and 2005. The results are in the journal Royal Society Open Science.

大西洋加蓬海域繁殖的彩票鲸鱼与印度洋马达加斯加附近繁殖的彩票鲸鱼,重叠的彩票曲目数量每年都在变化。这是注册根据2001年至2005年间对1500多种不同声音的彩票研究所得出的彩票结论。研究结果发表在《皇家学会娱乐开放科学》杂志上。

It makes sense that in some years there may be different oceanographic conditions, more patchily distributed prey, that may mean populations or individuals may have to move further to find food. And that might bring them into closer contact with neighboring populations and facilitate song exchange.

“可以得出一个结论:在某些年份,海洋条件可能会娱乐有所不同,猎物也更分散,这可能意味着座头鲸群或个体可能不得不去往更远的彩票地方寻找食物。而这可能会娱乐使得座头鲸们与邻近的彩票种群联系更紧密,从而促进歌曲交流。”

The findings present researchers with new opportunities to understand how culture is transmitted among animals. But it also allows even greater insight into the workings of populations of humpback whales.

这些发现给研究人员提供彩金新机会娱乐去彩金解文化是注册如何在动物间传播的彩票,也让我们对座头鲸种群的彩票活动有彩金更深入的彩票彩金解。

It shows you connectivity potentially on yearly timescales, which is what genetics information doesn't.

“研究展示彩金每年的彩票时间表存在潜在的彩票连通性,而遗传信息却不存在这一连通性。”

Genetic data can show that different populations had historical interactions. But songs can reveal how two populations interact on a much faster timescale. By combining song information from these populations with whales that breed off the Atlantic coast of Brazil, Rekdahl says researchers can gain a more comprehensive understanding of the dynamics of global humpback whale culture.

遗传数据表明,不同的彩票种群之间存在历史的彩票交互。但歌曲可以揭示两个种群如何在更快的彩票时标内相互影响。雷克达尔表示,通过将这些种群的彩票歌声信息与在巴西大西洋沿岸繁殖的彩票鲸鱼相结合,研究人员可以更全面地彩金解全球座头鲸文化的彩票动态。

Humpback whale song is an incredibly unique and complex display...and it's quite amazing how complex it is, and how it is such an amazing example of culture in animals.

“座头鲸的彩票歌声是注册一种独特而复杂到令人难以置信的彩票表演,歌声的彩票复杂程度令人惊讶,是注册动物文化的彩票一个惊人示例。
