Leg allometry in ants: extreme long-leggedness in thermophilic species.
Sommer S, Wehner R. Sommer S, et al. Arthropod Struct Dev. 2012 Jan;41(1):71-7. doi: 10.1016/j.asd.2011.08.002. Epub 2011 Oct 10. Arthropod Struct Dev. 2012. PMID: 21992805
The ant's estimation of distance travelled: experiments with desert ants, Cataglyphis fortis.
Sommer S, Wehner R. Sommer S, et al. J Comp Physiol A Neuroethol Sens Neural Behav Physiol. 2004 Jan;190(1):1-6. doi: 10.1007/s00359-003-0465-4. Epub 2003 Nov 12. J Comp Physiol A Neuroethol Sens Neural Behav Physiol. 2004. PMID: 14614570
In the present account we addressed the question of how the precision of the ant's estimate of its homing distance depends on the distance travelled. ...The quantitative relationship between training distance and the ant's estimate of this distance can be described …

Nest-mark orientation versus vector navigation in desert ants.
Bregy P, Sommer S, Wehner R. Bregy P, et al. Among authors: sommer s. J Exp Biol. 2008 Jun;211(Pt 12):1868-73. doi: 10.1242/jeb.018036. J Exp Biol. 2008. PMID: 18515716
When in particular experimental paradigms the two types of information--vector-based and landmark-based information--are made to compete with each other, the insect may weight either source more heavily depending on the navigational context and the animal's motivational st …

We review recent studies on this species concerning its use of habitual routes, distant landmarks, landmarks around the nest, and path integration, which is keeping track of the distance and direction traveled from one's starting point. ...
