...Leo Clement; Sebastian Schwarz; Blandine Mahot-Castaing; Antoine Wystrach ABSTRACT Solitary foraging insects such as desert ants rely heavily on vision for navigation. Although ants can learn visual scenes, it is unclear what cues they use to decide whether a scene is worth exploring at the first...

... altered. Cataglyphis Desert ants Homing Navigation Insect memory Insect learning Solitary foraging desert ants are expert navigators that seek and retrieve food morsels under extreme heat conditions. When foragers locate a bountiful food source they will shuttle rapidly back and forth...

...Kathrin Steck; Bill S. Hansson; Markus Knaden SUMMARY The desert ant, Cataglyphis fortis , uses both visual and olfactory cues to guide its return to the nest. The ants use vision-based path integration for long-distance navigation and memorize the visual and olfactory surrounding of the nest...

...Rüdiger Wehner; Martin Müller SUMMARY The inconspicuous nest entrances of the Namibian desert ant Ocymyrmex robustior are located on barren sandflats often devoid of any goal-defining landmark. Foragers that have returned by path integration to the rough area of the goal need a considerable amount...

...Tobias Merkle; Rüdiger Wehner SUMMARY This study deals with the influence landmark information has on the foraging behaviour of the desert ant, Cataglyphis fortis , especially with the interaction of such landmark information with the ants' path integration system. We show in the first experiment...

...Tobias Merkle; Markus Knaden; Rüdiger Wehner SUMMARY Foraging desert ants return to their starting point, the nest, by means of path integration. If the path-integration vector has been run off but the nest has not yet been reached, the ants engage in systematic search behavior. This behavior...
