Interaction of navigational cues

It is now clear that the outputs of different navigational modalities are simultaneously influencing the behaviour of navigating ants, but we don’t know the details of how this is implemented. In these new experiments Legge et al investigate this process. They confirm the previous result that ants will choose an intermediate direction when PI and learnt visual cues are discrepant, going further they show that the weighting shifts towards learnt views when those views are more informative. An interesting side note is that ants continue to integrate the cues even when the cues predict discrepant directions. This may represent a failure of the ants’ cue integration heuristic. Generally, it is considered optimal to choose one or other cue when they are very different.
