迁徙是现代须鲸生态的一个不可或缺的特征,迁徙的需求可能在塑造须鲸进化历史中发挥了关键作用。限制迁徙何时形成并评估其随时间的变化可能会对神秘鲸及其居住的海洋的进化产生有价值的见解。然而,目前直接评估史前神秘鲸迁徙的数据很少。在这里,我们展示了两种现代鲸藤壶(冠状藤壶)的方解石 δ18O 剖面准确地反映了其宿主鲸鱼的已知迁徙路线。然后,我们分析了东太平洋沿岸三个不同地点保存完好的冠冕化石,发现这些化石的 δ18O 剖面表现出与现代标本相似的趋势和范围。我们的研究结果表明,迁徙是座头鲸和灰鲸谱系中的一种古老行为,并且多个更新世种群正在进行与当今类似程度的迁徙。
Migration is an integral feature of modern mysticete whale ecology, and the demands of migration may have played a key role in shaping mysticete evolutionary history. Constraining when migration became established and assessing how it has changed through time may yield valuable insight into the evolution of mysticete whales and the oceans in which they lived. However, there are currently few data which directly assess prehistoric mysticete migrations. Here we show that calcite δ18O profiles of two species of modern whale barnacles (coronulids) accurately reflect the known migration routes of their host whales. We then analyze well-preserved fossil coronulids from three different locations along the eastern Pacific coast, finding that δ18O profiles from these fossils exhibit trends and ranges similar to modern specimens. Our results demonstrate that migration is an ancient behavior within the humpback and gray whale lineages and that multiple Pleistocene populations were undertaking migrations of an extent similar to those of the present day.
