Sea surface temperature (SST) time-series from the southwest Atlantic and the El Niño 4 region in the western Pacific were compared to an index of annual calving success of the southern right whale (Eubalaena australis) breeding in Argentina. There was a strong relationship between right whale calving output and SST anomalies at South Georgia in the autumn of the previous year and also with mean El Niño 4 SST anomalies delayed by 6 years. These results extend similar observations from other krill predators and show clear linkages between global climate signals and the biological processes affecting whale population dynamics.
将西南大西洋和西太平洋厄尔尼诺4区的海表温度（SST）时间序列与在阿根廷繁殖的南露脊鲸（Eubalaena australis）年度产犊成功率指数进行了比较。前一年秋季南乔治亚岛的露脊鲸产犊量与海温异常之间存在很强的相关性，同时也与延迟6年的厄尔尼诺4区平均海温异常存在很强的相关性。这些结果扩展了其他磷虾捕食者的类似观测结果，并表明全球气候信号与影响鲸鱼种群动态的生物过程之间存在明显联系。
