SUMMARY:

Competition is raised as a determining factor for the configuration of the local community in ants. Intraspecific competition, in turn, is a phenomenon with important ecological and evolutionary consequences, but its effect on natural populations remains uncertain. Therefore, the objective will be to verify the intraspecific competition between colonies of Dinoponera quadriceps in a natural environment. Ten neighboring colonies of D. quadriceps were chosen within the secondary Atlantic Forest area of the FLONA of Nísia Floresta / RN. Observations will take place between the months of July 2019 and June 2020. One ant will be observed at a time, from the time it leaves the nest until its return. The behaviors of food capture, agonistic interaction and chemical marking were recorded using the technique for all occurrences. The displacements and places where such behaviors occurred were marked with numbered flags and then measured with a compass and measuring tape. Preliminary results indicate that the colonies of D. quadriceps have areas of use that do not configure territories. In these areas, food capture is distributed. The workers carry out chemical marking in specific regions unrelated to overlapping areas with foraging areas of neighboring colonies. Agonistic interactions had a low frequency of observation. Abiotic factors such as temperature and humidity can influence conflicts between colonies.
