Desert ants use foraging distance to adapt the nest search to the uncertainty of the path integrator
Path integration enables desert ants to return to their nest on a direct path. However, the mechanism of path integration is error prone and the ants often miss the exact position of the nest entrance in which case they engage in systematic search behavior. The pattern produced by this search behavior is very flexible and enables the ants to take the errors into account that have been accumulated during foraging and homing. Here, we assess which parameter the desert ant Cataglyphis fortis uses...[Show more]
