How flexible is the systematic search behaviour of desert ants?

Merkle, Tobias; Wehner, Rudiger

Description

Foraging desert ants, Cataglyphis fortis, rely on path integration for navigation. If the path integrator has not led them to the exact position of the point of departure, the nest entrance, they start a systematic search for the nest. Previous studies have shown that the longer the preceding outbound run has been the less confidence an ant has in its path integrator. This lower confidence is expressed by wider search loops.
