     Over the course of socializations among 42 chimpanzees, including a total of 162 introduction events, we recorded early rearing histories, familiarity of individuals, use of a protected contact panel (PCP) which provides visual and limited physical contact, wounding in the first 24 hours, and success of the procedure. A procedure was considered successful if the animals were not separated due to aggression. Several factors were significantly related to wounding and/or success, including sex composition of the group (CHI (2) = 10.65, p = 0.005), familiarity of individuals (CHI (1) = 11.33, p = 0.001), and rearing (CHI (2) = 10.73, p = 0.005). Within the subgroup of introductions which incorporated the PCP, sex composition and success were not related (CHI (2) = 0.34, p = 0.84), but when the PCP was not incorporated, this relationship was significant (CHI (2) = 10.73, p = 0.005). When the PCP was used, success of the group and wounding were related (CHI (1) = 8.51, p = 0.004). This relationship was nearly significant when the PCP was not used (CHI (1) = 3.70, p = 0.054). A number of factors impact the success of chimpanzee socializations; using a PCP can ameliorate the impact of some of these factors. Continuing to investigate the various factors which contribute to successful chimpanzee socializations is an important part of captive chimpanzee management.
