摘要

蚂蚁物种在解决导航挑战以成功定位和到达目标位置时表现出行为共性。这些行为依赖于一个共享的导航策略工具箱,该工具箱在一系列动机背景下指导个人。然而,支持这些行为的机制是根据每个物种的栖息地和生态而调整的,其中一些表现出独特的导航行为。这导致蚂蚁导航者在如何依靠这个共享工具箱来实现目标方面存在明显差异。与单独觅食的物种相比,具有混合觅食结构的物种在工具箱中表现出明显的差异,它们部分在信息素标记的柱上导航。在这里,我们探索了西方草蚁(Formica obscuripes)的导航能力,这是一种杂交觅食物种,其导航机制尚未得到研究。我们描述了它们对视觉全景和路径积分器的依赖性,信息素的存在起到了非方向性保证提示的作用,促进了基于其他策略的持续定向。该物种还表现出回溯行为,这种行为发生在不熟悉的陆地线索和缺乏信息素的情况下,因此是基于在孤独和社会觅食物种中观察到的个体机制的组合。我们还描述了这些蚂蚁的一种新形式的无目标定向,这是一种由觅食者的路径整合系统调节的初始后退行为。这种行为会引导受干扰的外来觅食者沿着它们的外出路径返回一小段距离,然后恢复并重新定向回巢。

Directed retreat and navigational mechanisms in trail following Formica obscuripes.

Directed retreat and navigational mechanisms in trail following Formica obscuripes.

Ant species exhibit behavioural commonalities when solving navigational challenges for successful orientation and to reach goal locations. These behaviours rely on a shared toolbox of navigational strategies that guide individuals under an array of motivational contexts. The mechanisms that support these behaviours, however, are tuned to each species' habitat and ecology with some exhibiting unique navigational behaviours. This leads to clear differences in how ant navigators rely on this shared toolbox to reach goals. Species with hybrid foraging structures, which navigate partially upon a pheromone-marked column, express distinct differences in their toolbox, compared to solitary foragers. Here, we explore the navigational abilities of the Western Thatching ant (Formica obscuripes), a hybrid foraging species whose navigational mechanisms have not been studied. We characterise their reliance on both the visual panorama and a path integrator for orientation, with the pheromone's presence acting as a non-directional reassurance cue, promoting continued orientation based on other strategies. This species also displays backtracking behaviour, which occurs with a combination of unfamiliar terrestrial cues and the absence of the pheromone, thus operating based upon a combination of the individual mechanisms observed in solitarily and socially foraging species. We also characterise a new form of goalless orientation in these ants, an initial retreating behaviour that is modulated by the forager's path integration system. The behaviour directs disturbed inbound foragers back along their outbound path for a short distance before recovering and reorienting back to the nest.
