...-searching behaviour of Melophorus bagoti foragers within the familiar visual environment of their nest. First, by relating search behaviour to the information content of panoramic (360 deg) images, we found that searches were more accurate in visually cluttered environments. Second, as observed...

... about the actual development and nature of the view-based strategies used by ants in complex natural environments. Here, we constrained the knowledge of Melophorus bagoti ants to either the nest vicinity or a curved route (length 10 m) and analysed their initial direction when released at both novel...

...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...

... area, the Australian route-following desert ant Melophorus bagoti relies on the path integrator and consistently travels half the distance of the outward trip. However, when both the outward and inward trips are performed in plain and featureless channels, which blocks the distinct terrestrial visual...

... at each displaced distance that had zero turns (black), one turn (blue), no loops(green) and ≥one loop (red) are shown. Grid size is 1 m2. The most striking behaviour of homing Melophorus bagoti ants is their predominant reliance on distant nest-associated cues. Distant cues can be used...

...Ajay Narendra; Ken Cheng; Rüdiger Wehner SUMMARY Estimation of distance travelled (odometry) forms a vital part of navigation for solitarily foraging ants. In this study we investigated the properties of odometric memory in the Australian desert ant Melophorus bagoti . Ants were trained to travel...
