Studying animal behavior as collective phenomena is a powerful tool for understanding
social processes, including group coordination and decision-making. However, linking …

Attempts to explain differences in the size and structure of primate groups have argued that
they are a consequence of variation in the intensity of feeding competition caused by …

This comprehensive introductory text integrates evolutionary, ecological, and demographic
perspectives with new results from field studies and contemporary noninvasive molecular …

Via the current model on the evolutionary ecology of female social relationships, Sterck et
al.(1997) argue that ecological conditions determine how competition over food resources …

Dominance rank in female chimpanzees correlates positively with reproductive success.
Although a high rank obviously has an advantage for females, clear (linear) hierarchies in …

Several models have been proposed to explain the variation that exists in female social
relationships among diurnal primate species. While there are similarities among them …

There is an established and very influential view that primate societies have identifiable,
persistent social organizations. It assumes that association patterns reflect long-term …

The idea that competition and aggression are central to an understanding of the origins of
group‐living and sociality among human and nonhuman primates is the dominant theory in …

In most mammalian species, females regularly interact with kin, which is expected to reduce
aggressive competitive behaviour among females. It may thus be difficult to understand why …

Many studies have shown that low dominance status within a social group is associated with
elevated glucocorticoid hormone production, a common index of physiological stress …
