Social interactions between workers in a colony do not happen randomly, since workers decide how often they will interact and who they will interact with. Interactions rate in the colony are regulated by the density of ...

In order to characterize the seasonal and daily rhythm of Dinoponera quadriceps foraging activity in natural environment, four colonies of D. quadriceps were observed in an area of secondary Atlantic forest in northeastern ...
