Collective decision making through food recruitment

A series of experiments shows how the andLasius niger uses its trail recruitment system to select between two food sources. Simultaneously presented with to 1M sucrose solution it concentrates on one of them. When offered a 1M solution together with a 0.1M solution it selects the richer source, unless the trait to the 0.1M source had become well-developed before the 1M source was introduced. In the same situation, however, the group/mass recruiting antTetramorium caespitum uses its more individual transmission of information to switch to the 1M source. A mathematical model describes these processes and its dynamics reflect the experimental results.

La prise de décision collective à travers le recrutement alimentaire


Nous présentons une série d'expëriences qui montrent comment la fourmiLasius niger peut utiliser son système des recruitement par piste afin de sélectionner une dfes deux sources de nourriture. Sil on leur offire simultanément deux solution 1M de saccharose, la sojciét'e concentre son activité sur l'une des deux. Si l'on offre deux solutions, une de 1M et l'autre de 0.1M, elle sélectionne la plus riche, à mons que la piste qui mène à la source 0.1M soit déjà bien développée au moment où l'on introduit la source 1M. Face à la même situation, la fourmiTetramorium caespitum, qui recrute par groupe/masse, utilise son mode de transmission d'information plus, individuel pour changes son exploitation vers la source 1M. Un modèle mathématique décrit ces processus, dont la dynamique correspond bien aux observations expérimentales.
