Ants use pedometers to find home. Desert ants have an internal system - like a pedometer - that keeps track of how many steps they take, according to a new study. The insects seem to rely on

Other studies have shown that once ants find a good source of food, they teach other ants how to find it. The ant "pedometer" technique was first proposed in 1904, but it remained untested until now.

The "Pedometer Effect" The regular ants walked right to the nest and went inside. The ants on stilts walked right past the nest, stopped and looked around for their home.

Ants use path integration to navigate: to get back home, they keep track of their travel direction, by using a celestial compass, and their travel distance. Until now, scientists were less clear about how ants measured distance, strongly suspecting that they use an internal pedometer. This takes into account an ant's stride length and stride

SUMMARY. Desert ants, Cataglyphis, use path integration as a major means of navigation. Path integration requires measurement of two parameters, namely,direction and distance of travel. Directional information is provided by a celestial compass, whereas distance measurement is accomplished by a stride integrator, or pedometer. Here we examine the recently demonstrated pedometer function in

The ants were trained to walk from their nest entrance to a feeder, over a distance of 10 m and in a linear alloy channel (Fig. 1, top).After at least 1 day of training, the animals were caught at the feeding site and transferred to a test channel, aligned parallel to the training channel (Fig. 1, bottom).Once transferred into this test channel, the ants performed their homebound runs, and we

As expected, manipulating the length of legs scrambled the ants' pedometer. Ants walking on stilts walked 10.55 metres to return to the starting point, and ants with shortened legs took 10.25 metres.

The ants on stilts went about 5 meters too far before stopping to search for the nest, whereas the stumpy ants stopped about 5 meters too short, the team reports 29 June in Science. (Control ants got back home just fine.) After the modified ants were returned to the nest, they were able to go out and get back home just as accurately as normal

The ants on stilts had a lengthened stride and marched past their goal, whereas the stump-legged ants stopped short of their goal, suggesting that stride length indeed serves as an ant pedometer

A normal ant and an ant with stilts. It appeared, the scientists say, that the ants were using the number of steps they took, not the actual distance traveled, to gauge how far they had gone. After a few days with their new legs, however, the ants seemed to reset their pedometers.

The ant appears to use an internal pedometer to count its steps in a harsh environment where odors quickly vanish, enabling it to "count back" to its nest. When stilts were glued on to the ants legs, they overshot the distance of their nests, while ants with cut legs traveled short of their nest. It's suspected that while the ants unlikely have

Comparative analyses revealed that several closely related fire ant species also possess long centromeres. Conclusions: Our results are consistent with a model of simple runaway centromere expansion due to centromere drive. We suggest expanded centromeres may be more prevalent in hymenopteran insects, which use haplodiploid sex determination
