J'ai vu ça sur facebook :
http://news.nationalgeographic.com/news ... tilts.htmlThe study, to be published in tomorrow's issue of the journal Science, found that changing the ants' leg lengths did indeed scramble their internal pedometers.
For the ants on stilts, each step now covered more distance than they were used to. They overshot the nest, running an average of more than 50 percent farther than they should have.
Those with shortened legs undershot by nearly as much.
Interestingly, the ants quickly adjusted to their new leg lengths.
Alors ce phénomène serait-il exclusif aux espèces vivant au Sahara ou les fourmis ne se repéreraient-elles en fait juste pas ou en tout cas pas entièrement (voire seulement si besoin) avec les phéromones ?
