A simple model of recruitment-based foraging in ants illustrates the idea that synchronized patterns of activity can endow a colony with the ability to forage more efficiently when a minimal number of active individuals is required to establish and maintain food source exploitation. This model,...

A simple response threshold model is used to explain a pattern of division of labour observed in the ponerine ant Ectatomma ruidum, where it was found that prey-foraging behaviour could be subdivided into two categories: stinging and transporting. Stingers kill live prey and transporters carry...
