Published: 01 September 2011
...Cornelia Bühlmann; Ken Cheng; Rüdiger Wehner SUMMARY Two species of desert ants – the North African Cataglyphis fortis and the central Australian Melophorus bagoti – differ markedly in the visual complexity of their natural habitats: featureless salt pans and cluttered, steppe-like terrain...

...Tobias Seidl; Rüdiger Wehner SUMMARY Place defining landmarks that have been studied intensively in insect navigation are large, voluminous objects visible to the insect from quite some distance. Here, we show that in desert ants, Cataglyphis fortis ,local variations in ground properties can also...

...Harald Wolf; Rüdiger Wehner SUMMARY During foraging trips, desert ants Cataglyphis fortis do not rely only on their well-studied path integration system, they also use olfactory cues when approaching a familiar food source. When a wind is blowing from a constant direction, as is characteristic...

.... From the angles of the ants' return path on the test field one can infer which property of the hill segment was fed into the ants'path integration module, the actual walking distance or the ground distance. The results show clearly that it is the ground distance that Cataglyphis fortis feeds into its...

...R. J. Vickerstaff; E. A. Di Paolo SUMMARY We use a genetic algorithm to evolve neural models of path integration,with particular emphasis on reproducing the homing behaviour of Cataglyphis fortis ants. This is done within the context of a complete model system, including an explicit representation...
