Naturalistic path integration of Cataglyphis desert ants on an air cushioned lightweight spherical treadmill
... An interesting difference in our data is that the ants from captive laboratory colonies seem to show a less straight approach phase when running back to their nest site on the treadmill (Fig. 5G). A possible explanation ...
