觅食的蚂蚁能够获得并保持对巢穴周围和沿着已知路线的全景线索的长期记忆。在这里，我们探讨觅食的能力，学习和保留天际线线索经验，只有出站或进站部分的觅食之旅。觅食暴露于天际线的出站部分显示这些线索的单一试验学习。此外，这些只外出觅食的觅食者的导航性能与经历过完整路线的觅食者相当。相比之下，觅食经验的天际线只在入境部分，入境只觅食，需要5次旅行，成功地学习这些线索。这些表现差异在长期记忆保持方面持续存在。Outbound-Only觅食者在3天的延迟后成功定向，并表现出与完全路线控制相似的表现，而Inbound-Only觅食者在3天后不再能够成功定向到这些线索。此外，长期记忆形成的天际线线索似乎需要多个演示文稿，觅食只有一个出站的天际线的经验不能成功地定位后的延迟。我们的研究结果表明，陆地线索的学习和保留是更强大的线索时，经历了外出段的觅食之旅。
Foraging ants are able to acquire and retain long-term memories of panorama cues around the nest and along known routes. Here we explore foragers' ability to learn and retain skyline cues experienced on only the outbound or inbound portion of the foraging trip. Foragers exposed to the skyline on the outbound portion showed single trial learning of these cues. Furthermore, the navigational performance of these Outbound-Only foragers was on par with foragers that experienced the full route. In contrast, foragers experiencing the skyline only on the inbound portion, Inbound-Only foragers, took 5 trips to successfully learn these cues. These performance differences persisted for long-term memory retention. Outbound-Only foragers successfully oriented after a 3-day delay and showed similar performance to the full route control, whereas Inbound-Only foragers were no longer able to orient successfully to these cues after 3days. Additionally, long-term memory formation of skyline cues appears to require multiple presentations, as foragers with only one outbound experience of the skyline could not successfully orient after the delay. Our results suggest that terrestrial cue learning and retention is more robust when cues are experienced on the outbound segment of the foraging trip.
