摘要

对蚂蚁个体导航的大量研究表明,路径整合和视觉引导导航是蚂蚁导航工具箱的重要组成部分,是成功导航的充分机制。这些机制相互作用的行为标志之一是,有经验的觅食者发展出独特的路线,这需要单个蚂蚁具有个人和独特的视觉记忆,它们使用这些记忆来指导巢穴和觅食地点之间的习惯性路线。然而,大多数蚂蚁生活在复杂杂乱的环境中,社会信息素的踪迹往往是这些觅食者集体招募、组织和导航的一部分。我们不知道在复杂的自然环境中,个人导航是如何与共同路径上的集体行为相互作用的。因此,我们在这里问木蚁,如果在密集杂乱的林地中觅食,它们沿着共享路径重复地走相同的路线,还是在共享路径中选择不同的路径。我们记录了20只木蚁在其自然林地栖息地的3条长长的归巢轨迹。我们发现,在高度复杂的视觉景观中,木蚁沿着共享路径导航时,会遵循特殊的路线。这表明,即使在有化学痕迹信息的混乱环境中,蚂蚁也依赖于个体记忆来进行习惯性路线指导。我们认为视觉线索可能是特异路径的主要感官形式。这些实验揭示了蚂蚁或昆虫是如何在复杂的多模式环境中导航的。

Trail using ants follow idiosyncratic routes in complex landscapes.

Trail using ants follow idiosyncratic routes in complex landscapes.

A large volume of research on individually navigating ants has shown how path integration and visually guided navigation form a major part of the ant navigation toolkit for many species and are sufficient mechanisms for successful navigation. One of the behavioural markers of the interaction of these mechanisms is that experienced foragers develop idiosyncratic routes that require that individual ants have personal and unique visual memories that they use to guide habitual routes between the nest and feeding sites. The majority of ants, however, inhabit complex cluttered environments and social pheromone trails are often part of the collective recruitment, organisation and navigation of these foragers. We do not know how individual navigation interacts with collective behaviour along shared trails in complex natural environments. We thus asked here if wood ants that forage through densely cluttered woodlands where they travel along shared trails repeatedly follow the same routes or if they choose a spread of paths within the shared trail. We recorded three long homing trajectories of 20 individual wood ants in their natural woodland habitat. We found that wood ants follow idiosyncratic routes when navigating along shared trails through highly complex visual landscapes. This shows that ants rely on individual memories for habitual route guidance even in cluttered environments when chemical trail information is available. We argue that visual cues are likely to be the dominant sensory modality for the idiosyncratic routes. These experiments shed new light on how ants, or insects in general, navigate through complex multimodal environments.
