Abstract

Bats are known for their ability to use echolocation for obstacle avoidance and orientation. However, the extent to which bats utilize their highly local and directional echolocation for kilometer-scale navigation is unknown. In this study, we translocated wild Kuhl’s pipistrelle bats and tracked their homing abilities while manipulating their visual, magnetic, and olfactory sensing and accurately tracked them using a new reverse GPS system. We show that bats can identify their location after translocation and conduct several-kilometer map-based navigation using solely echolocation. This proposition was further supported by a large-scale echolocation model disclosing how bats use environmental acoustic information to perform acoustic cognitive map–based navigation. We also demonstrate that navigation is improved when using both echolocation and vision.

回声定位蝙蝠基于声学认知地图的导航

众所周知，蝙蝠能够利用回声定位来避开障碍物和确定方向。然而，蝙蝠在多大程度上利用其高度局部性和方向性的回声定位进行千米级导航尚不清楚。在这项研究中，我们转移了野生库氏琵琶蝠，在操纵它们的视觉、磁力和嗅觉的同时追踪它们的归巢能力，并使用新的反向全球定位系统对它们进行精确追踪。我们的研究结果表明，蝙蝠能在移位后识别自己的位置，并能仅利用回声定位进行几公里的地图导航。大规模回声定位模型进一步支持了这一观点，该模型揭示了蝙蝠如何利用环境声学信息进行基于声学认知地图的导航。我们还证明，同时使用回声定位和视觉时，导航效果会更好。

期刊介绍： Science is a leading outlet for scientific news, commentary, and cutting-edge research. Through its print and online incarnations, Science reaches an estimated worldwide readership of more than one million. Science’s authorship is global too, and its articles consistently rank among the world's most cited research. Science serves as a forum for discussion of important issues related to the advancement of science by publishing material on which a consensus has been reached as well as including the presentation of minority or conflicting points of view. Accordingly, all articles published in Science—including editorials, news and comment, and book reviews—are signed and reflect the individual views of the authors and not official points of view adopted by AAAS or the institutions with which the authors are affiliated. Science seeks to publish those papers that are most influential in their fields or across fields and that will significantly advance scientific understanding. Selected papers should present novel and broadly important data, syntheses, or concepts. They should merit recognition by the wider scientific community and general public provided by publication in Science, beyond that provided by specialty journals. Science welcomes submissions from all fields of science and from any source. The editors are committed to the prompt evaluation and publication of submitted papers while upholding high standards that support reproducibility of published research. Science is published weekly; selected papers are published online ahead of print.
