Evaluation of social compatibility in an all‐male group of chimpanzees (Pan troglodytes) by means of social network analysis
The study here presented provides preliminary data regarding social compatibility of an all-male group of five chimpanzees (Pan troglodytes), assessed by means of a social network analysis (SNA). The study was conducted at the Fundació Mona (Girona, Spain), where data on social behavior were collected in two consecutive 2-week periods using continuous focal animal sampling […]
