DESCRIPTION:Danielle MERSCH\, Faculté de biologie et de médecine\, Depar
 tment of Ecology and Evolution\, University of Lausanne\nAnts live in orga
 nized societies with a marked division of labor among workers\, but little
  is known about how this is generated. We use a tracking system to continu
 ously monitor individually-tagged workers in six colonies of the ant Campo
 notus fellah over 41 days. Network analyses of over 9 million interactions
  revealed three distinct groups that differ in behavioral repertoires. Eac
 h group represents a functional behavioral unit with workers moving from o
 ne group to the next as they age. The rate of interactions was much higher
  within- than between groups. The precise information on spatial and tempo
 ral distribution of all individuals permitted calculation of the expected 
 rates of within- and between-group interactions. These values suggest that
  the network of interaction within colonies is primarily mediated by age-i
 nduced changes in the spatial location of workers.
