Eficácia de placas educativas no descarte de resíduos sólidos urbanos e à não alimentação do sagui-de-trufo-preto (Callithrix penicillata)

In this study, we investigated the effectiveness of educational boards in raising awareness among the population of Quirinopolis regarding the disposal of solid waste and non-feeding of Callithrix penicillata in the Botanical Garden of the State University of Goias. We evaluated the differences in the total weight of waste before and after implementation of the educational signs, and the interactions between the factors: use of the sign [before, after] with the type of residue, and we tested the association between the weight of the residues with the time scale for each type of residue. There was a decrease in the weight of paper, plastic and glass inside; and paper, plastic and metal in the surroundings of the Botanical Garden, and the presence of food for the individuals of marmosets was not observed after the use of the educational plates. These results support the effectiveness of educational boards. However, more research is needed to find out if this pattern is maintained in other Environmental Education scenarios.
