Social structure and social organization are intimately related as a product of the demography and of the different kinds of social relationships between members. Group size is one of the main factors that influence the formation and maintenance of a captive group. Some studies recognize that captivity may causes changes in behavior with respect to their conspecifics in nature. Social Network Analysis with Generalized Linear Models were combined to know the effect of social organization on social behavior of nine groups of spider monkeys in captivity rescued from illegal trafficking, and if these, in turn, have an influence on the properties on social networks. Results suggest that group size and age affect social interactions and the quality of the spider monkey networks in captivity, with higher affiliation in larger groups (≥4 members) and when juveniles and breeding are present; the proportion of sexes does not significantly affect, but it is more agonistic when the proportion in the group is similar, agonism is greater when the number of males surpasses that of females and less agonistic when it is unisexual. These data will serve to improve patterns of grouping and formation of new groups and thus improve animal welfare by increasing affiliative behaviors and reducing agonism and to encourage typical behavior. This study will contribute to the understanding of behavioral flexibility and social tolerance processes.
