In most taxa with male dimorphisms, some males are large in body size with exaggerated secondary sexual characters (exaggerated morph), whereas other males in the same population are small and have reduced secondary sexual characters (reduced morph). What selective pressures cause male...

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...

Models for the behavior of ants and pedestrians are studied in a unified way in this paper. Each ant follows pheromone … put by preceding ants, hence creating a trail on the ground, while pedestrians also try to follow others in a crowd for … average speed of the ants on their density, which can be well analyzed by the zero-range process. We also show that this …
