Do desert ants smell the scenery in stereo?
-- K. Steck and M. Knaden, and B. Hansson,(2010) Animal Behaviour.
Our results suggest that the ants had learned the olfactory scenery around their nest. Furthermore, unilaterally antennectomized ants could not pinpoint the nest within a two-dimensional array. Hence, this kind of orientation depends on the simultaneous input of both antennae, that is, on a stereo sense of smell.
