... 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...
