| Outline of Final Research Achievements |
In this study, by means of quantitative experiments and mathematical modeling for foraging behavior, we elucidated the mechanism through which group of ants without specific leader are able to perform sophisticated collective behavior and flexible task allocation and to get advanced functions. We got following results; 1.In each colony hierarchy for the foraging frequency among ants exists.
2.If active foraging ants are removed from a colony, a part of remaining ants get more active to compensate the activity of removed ants. 3.The rank order of foraging activity among a colony of ants does not greatly change in short time range but shows a remarkable change in long range of time.
