Resumo |
Does the social life entail greater individual activity, and consequently, higher energy expenditure? To answer this question, we hypothesized that there is higher CO2 production, when we increase the size of the group of workers, and hence a higher energy cost to the individual when they are in groups. Thus, groups of 10, 20, 30, 40 and 50 workers were sealed in a hermetic chamber for 24 hours. Subsequently, we performed the measurements of the CO2 concentration in the containers respirometric. Unlike the expected CO2 production, and consequently the individual energy expenditure did not differ when we increase the size of the group of workers. Thus, we refuted the hypothesis that the group size leads to a higher cost individual energy, since the greater interaction between individuals. In conclusion, our study with Atta sexdens rubropilosa workers determined that the size of the group does not lead to higher energy costs individual and CO2 production, and therefore energy expenditure similar individual, independent of the group size. |
