Kinship and Intragroup Social Dynamics in Two Sympatric African Colobus Species

摘要: Kinship has been described as a major factor shaping primates' social dynamics, with individuals biasing their affiliative interactions to related counter- parts. However, it also demonstrated that, under certain circumstances, bonding can be established in the absence of kin. The fact that Colobus polykomos (western black-and-white colobus) and Procolobus badius temminckii (Temminck' sr ed often live sympatry (subject same ecological/anthropogenic pres- sures) but exhibit contrasting systems makes them good models test which factors shape systems.
