Abstract

Solitarily foraging ant species differ in their reliance on their two primary navigational systems- path integration and visual learning. Despite many species of Australian bull ants spending most of their foraging time on their foraging tree, little is known about the use of these systems while climbing. "Rewinding" displacements are commonly used to understand navigational system usage, and work by introducing a mismatch between these navigational systems, by displacing foragers after they have run-down their path integration vector. We used rewinding to test the role of path integration on the arboreal and terrestrial navigation of M. midas. We rewound foragers along either the vertical portion, the ground surface portion, or across both portions of their homing trip. Since rewinding involves repeatedly capturing and releasing foragers, we included a nondisplacement, capture-and-release control, in which the path integration vector is unchanged. We found that rewound foragers do not seem to accumulate path integration vector, although a limited effect of vertical rewinding was found, suggesting a potential higher sensitivity while descending the foraging tree. However, the decrease in navigational efficiency due to capture was larger than the vertical rewinding effect, which along with the negative impact of the vertical surface, and an interaction between capture and rewinding, may suggest aversion rather than path integration caused the vertical rewinding response. Together these results add to the evidence that M. midas makes minimal use of path integration while foraging, and the growing evidence that they are capable of quickly learning from aversive stimulus.

重复垂直和水平路线对澳大利亚牛蚁导航性能的影响
单独觅食的蚂蚁物种在依赖其两个主要导航系统--路径整合和视觉学习--方面存在差异。尽管许多种类的澳大利亚牛蚁把大部分觅食时间都花在觅食树上,但人们对这些系统在攀爬时的使用情况却知之甚少。"倒带 "位移通常用于了解导航系统的使用情况,其工作原理是在这些导航系统之间引入不匹配,在觅食者完成路径整合矢量后对其进行位移。我们使用倒带法测试路径整合对米达斯树栖和陆地导航的作用。我们沿垂直部分、地表部分或两部分的归巢行程对觅食者进行倒带。由于倒带涉及反复捕捉和释放觅食者,我们加入了一个非位移、捕捉和释放控制,其中路径整合矢量保持不变。我们发现,虽然垂直倒带的影响有限,但倒带的觅食者似乎不会积累路径整合矢量,这表明在觅食树下降时,觅食者可能会有更高的灵敏度。然而,捕获导致的导航效率下降大于垂直后退的影响,再加上垂直表面的负面影响以及捕获和后退之间的交互作用,可能表明是厌恶而不是路径整合导致了垂直后退反应。这些结果进一步证明,鳉鱼在觅食时极少使用路径整合,而且越来越多的证据表明,它们能够从厌恶刺激中快速学习。
