Understanding the biogeography of a species begins by mapping its presence over time and space. The use of home ranges, breeding and feeding areas, migration paths and movement patterns between the two are also inherent to their ecology. However, this is an overly simplified view of life histories. It ignores nuanced and complex exchanges and responses to the environment and between conspecifics. Having previously advocated for a more species-centric approach in a discussion of ‘whale geography’, I look to better understand the driving factors of migrations, and the information streams guiding the movement, which is key to the biogeography of large whale species. First, I consider the processes underlying the navigation capacities of species to complete migration, and how, and over what scales, sensory information contributes to cognitive maps. I specifically draw on examples of large-scale, en masse migrators to then apply this to whales. I focus on the acoustic sense as the principal way whales gain and exchange information, drawing on a case study of grey whale (Eschrichtius robustus) calling behaviour to illustrate my arguments. Their consistent employment of far-propagating calls appears to be tied to travel behaviours and probably aids navigation and social cohesion. The range over which calls are being propagated to conspecifics, or perhaps being echoed back to the individual, underlies the distance over which the cognitive maps are being both formed and employed. I believe understanding these processes edges us closer to understanding species biogeography.

鲸鱼地理学:一种应用于迁徙的以物种为中心的方法

了解一个物种的生物地理学首先要绘制它在时间和空间上的存在。栖息地的使用、繁殖和饲养区、迁徙路径和两者之间的运动模式也是它们的生态所固有的。然而,这是对生活史的过于简化的看法。它忽略了对环境和同类之间细微而复杂的交流和反应。之前在讨论“鲸鱼地理”时提倡采用更以物种为中心的方法,我希望更好地了解迁徙的驱动因素,以及指导运动的信息流,这是大型鲸鱼物种生物地理学的关键。首先,我考虑了物种完成迁移的导航能力背后的过程,以及感官信息如何以及在多大程度上有助于认知地图。我特别借鉴了大规模的大规模迁徙者的例子,然后将其应用于鲸鱼。我将听觉作为鲸鱼获取和交换信息的主要方式,并以灰鲸 (Eschrichtiusrobustus) 呼叫行为的案例研究来说明我的论点。他们对远距离呼叫的持续使用似乎与旅行行为有关,并且可能有助于导航和社会凝聚力。呼叫被传播到同种或可能被回响到个体的范围是认知地图形成和使用的距离的基础。我相信了解这些过程会使我们更接近于了解物种生物地理学。我将听觉作为鲸鱼获取和交换信息的主要方式,并以灰鲸 (Eschrichtiusrobustus) 呼叫行为的案例研究来说明我的论点。他们对远距离呼叫的持续使用似乎与旅行行为有关,并且可能有助于导航和社会凝聚力。呼叫被传播到同种或可能被回响到个体的范围是认知地图形成和使用的距离的基础。我相信了解这些过程会使我们更接近于了解物种生物地理学。我将听觉作为鲸鱼获取和交换信息的主要方式,并以灰鲸 (Eschrichtiusrobustus) 呼叫行为的案例研究来说明我的论点。他们对远距离呼叫的持续使用似乎与旅行行为有关,并且可能有助于导航和社会凝聚力。呼叫被传播到同种或可能被回响到个体的范围是认知地图形成和使用的距离的基础。我相信了解这些过程会使我们更接近于了解物种生物地理学。他们对远距离呼叫的持续使用似乎与旅行行为有关,并且可能有助于导航和社会凝聚力。呼叫被传播到同种或可能被回响到个体的范围是认知地图形成和使用的距离的基础。我相信了解这些过程会使我们更接近于了解物种生物地理学。他们对远距离呼叫的持续使用似乎与旅行行为有关,并且可能有助于导航和社会凝聚力。呼叫被传播到同种或可能被回响到个体的范围是认知地图形成和使用的距离的基础。我相信了解这些过程会使我们更接近于了解物种生物地理学。
