对昆虫导航的研究表明，昆虫拥有有趣且复杂的视觉导航行为。正在进行的研究旨在帮助我们了解如何在自然复杂的环境中控制这些行为。行为研究的必要补充是了解动物行为的感官生态。为此，我们分析了蚂蚁对栖息地的视角，在该栖息地中对沙漠蚂蚁的导航进行了深入研究。我们的分析结果表明：即使在杂乱的环境中，用于导航和路线引导的简约视觉策略在行为上有用的距离上也是有效的；仅使用天际线高度作为输入，这些策略就可以有效发挥作用；使用存储的视图作为视觉指南针的简单性和有效性使其成为一种可行且强大的路线引导机制。
Studies of insect navigation have demonstrated that insects possess an interesting and sophisticated repertoire of visual navigation behaviours. Ongoing research seeks to help us understand how these behaviours are controlled in natural complex environments. A necessary complement to behavioural studies is an understanding of the sensory ecology within which an animal behaves. To this end we have analysed ants'-perspective views of a habitat within which desert ant navigation is well studied. Results from our analysis suggest that: parsimonious visual strategies for homing and route guidance are effective over behaviourally useful distances even in cluttered environments; that these strategies can function effectively using only the skyline heights as input; and that the simplicity and efficacy of using stored views as a visual compass makes it a viable and robust mechanism for route guidance.
