DESCRIPTION:Speaker: Deborah Gordon\nAbstract: Like many complex biological
  systems\, an ant colony operates without central\ncontrol. Each ant respo
 nds to its interactions with other ants nearby. In the\naggregate\, these 
 stochastic\, dynamical networks of interaction regulate colony\nbehavior.\
 nAnts are extremely diverse\, and species differences in collective behavi
 or reflect\nrelations with diverse environments. A long-term study of dese
 rt seed-eating ants\nshows how colonies regulate foraging activity accordi
 ng to food availability and\nhumidity\, and how natural selection is shapi
 ng collective behavior in current\ndrought conditions.\nSimilar patterns o
 f interaction\, such as network motifs and feedback loops\, are used\nin m
 any natural collective processes\, probably because they have evolved\nind
 ependently under similar pressures. Examples from ants provide a starting 
 point\nfor examining more generally the fit between the particular pattern
  of interaction\nthat regulates activity\, and the environment in which it
  functions.
