            Different Humpback Whale Groups Meet to Jam

            来自不同海域的座头鲸群会聚在一起吃?#21462;?#20132;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.

            雄性座头鲸是海洋世界里的歌唱家。这些海洋巨无霸唱出的曲调可能在数百英里之外都能听得?#21073;?#36825;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,在非洲大陆两端的南大西洋和印度两个不同海域里的座头鲸所唱的旋律居然是一样的。

            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.

            “这些歌曲无疑是座头鲸从同伴处学会的。这被认为是文化横向传播的最?#32654;?#23376;——同伴传给同伴,而不是父母传给后代。”

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

            野生动物保护协会“海洋巨人项目”的海洋保护科学家梅琳达·雷克达尔表示?#20581;?/p>

            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.

            国际捕鲸委员会在?#20064;?#29699;已经?#21857;?#20102;7个不同的座头鲸繁殖种?#28023;?#36825;些鲸鱼每年都在同样温暖的热带水域交配?#22836;敝场?#24403;交配季节结束后,鲸鱼就会迁徙到寒冷的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座头鲸进行遗传学和摄影调查发现,生活在寒冷地区的雄性座头鲸会与来自不同繁殖群体的雄性座头鲸互动。但是,科学家们并不知道这次会面给座头鲸提供了一个进行声乐交流的机会——鲸鱼们在会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鲸鱼与印度洋马达加斯加附近繁殖的鲸鱼,重叠的曲目数量每年都在变化。这是根据2001年至2005年间对1500多种不同声音的研究所?#36152;?#30340;结论。研究结果发表在《皇家学会开放科学》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?#36152;?#19968;个结论:在某些年份,海洋条件可能会有所不同,猎物也更分散,?#39274;?#33021;意味着座头鲸群或个体可能不得不去往更远的地方寻找食物。而?#39274;?#33021;会使得座头鲸们与邻近的种群联系更紧密,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了新机会去了解文化是如何在动物间传播的,也让我们对座头鲸种群的活动有了更深入的了解。

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

            “研?#31354;故?#20102;每年的时间表存在潜在的连通性,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,不同的种群之间存在历史的交互。但歌曲可以揭示两个种群如何在更快的时标内相互影响。雷克达尔表示,通过将这些种群的歌声信息与在巴西大西洋沿岸繁殖的鲸鱼相结合,研究人员可以更全面地了解全球座头鲸文化的动态。

            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.

            “座头鲸的歌声是一种独特而复杂到令人难以置信的表演,歌声的复杂程度令人惊讶,是动物文化的一个惊人示例。
