“…A second piece of information available to both partners is that the dominant of a dyad on average grooms less than the subordinate does under comparable circumstances. This asymmetry is explained by the fact that dominants can offer alternative commodities, such as tolerance in food patches and support in conflicts, that subordinates cannot offer Barrett and Henzi 2006;Chancellor and Isbell 2009;Henzi et al 2003;Newton-Fisher and Lee 2011;Port et al 2009;Tiddi et al 2011Tiddi et al , 2012. We do not have the impression that vervets can coerce subordinate into grooming them as has been reported for Barbary macaques (Carne et al 2011), and grooming bouts were not continued by subordinates under any overt aggression or threat by dominants.…”

Mutual grooming plays a central role in the establishment and maintenance of social relationships in primates. Allogrooming has two main functions: hygiene and bonding with partners. The duration of grooming bouts is commonly used in studies of the functional aspects of grooming, but few reflect on the proximate mechanisms that determine grooming bout lengths. As it is highly unlikely that groomer and groomee prefer exactly the same bout length, we are likely to observe the result of some form of negotiation. We currently lack information about the signals that primates employ to inform others about their intentions and desires concerning grooming interactions. From October 2006 until April 2007 we studied three behaviors shown in grooming interactions that could potentially have a signaling function in the negotiation process over the initiation and length of grooming bouts among adult females of two vervet groups freely ranging in the Loskop Dam Nature Reserve, South Africa: approaching another individual as far as that resulted in a grooming session, changing of the body position by the groomed individual, and lip smacking. We found that "approach" did not reliably predict which individual would receive grooming first, although approaching individuals groomed significantly more than those approached. Thus, in Erica van de Waal and Martina Spinelli are joined first authorship.

“…We examined the extent to which the behaviors were reciprocated between male partners and whether their relative age was a factor in the distribution and reciprocation. We examined reciprocation according to partner choice based on benefits received, which relies on acrossdyad comparisons (Tiddi et al 2011; this mechanism was called reciprocal partner choice by Schino and Aureli 2009), instead of within-dyad temporal relation between events (i.e., classical reciprocal altruism: Trivers 1971). Furthermore, we examined the extent to which each behavior was associated with the other two behaviors.…”

In social organizations characterized by male philopatry, social relationships between males are argued to be the strongest. Little is known about the social relationships of philopatric male spider monkeys. To address this limitation, we investigated social relationships among individually recognized wild adult male spider monkeys from two well-habituated communities in the Yucatan Peninsula, Mexico, focusing on affiliative behaviors important in regulating male social relationships, including grooming, embracing, arm-wrapping, and grappling. We examined whether behaviors were reciprocated between male partners and whether age was a factor in how the behaviors were distributed or reciprocated, by examining differences between younger adult males (<10 years) and older adult males (≥14 years). Although we found evidence that affiliative behaviors were overall reciprocated between spider monkey adult males, there were pronounced differences in the interactions depending on their relative age. Reciprocation in grooming and embraces between same-age males suggests their relationships are valuable to both partners. Among different-age dyads, younger males gave more embraces than they received, were the initiators of grappling and arm-wrapped more often than with same-age males, suggesting relationships between younger and older males are more risky. This confirms that younger males are attracted to older males, probably because they value relationships with older males more than the reverse, but they are also at risk.

“…Grooming underpins strong social bonds that can last several years [3], but in the short-term, it is also traded as a commodity in a biological market in return for grooming or other services. Such services can include tolerance from dominant animals that allow subordinates to share their feeding sites [10,11]. Research in our study population of wild chacma baboons (Papio ursinus) similarly indicates an exchange of grooming for tolerance at feeding sites, because grooming and co-feeding are strongly correlated between individuals, dominant animals play a central role in co-feeding [12], and subordinates prefer food patches containing individuals with whom they have a positive grooming balance [13].…”

Evidence for varying social strategies across the day in chacma baboons

Strong social bonds can make an important contribution to individual fitness, but we still have only a limited understanding of the temporal period relevant to the adjustment of social relationships. While there is growing recognition of the importance of strong bonds that persist for years, social relationships can also vary over weeks and months, suggesting that social strategies may be optimized over shorter timescales. Using biological market theory as a framework, we explore whether temporal variation in the benefits of social relationships might be sufficient to generate daily adjustments of social strategies in wild baboons. Data on grooming, one measure of social relationships, were collected from 60 chacma baboons (Papio ursinus) across two troops over a six month period. Our analyses suggest that social strategies can show diurnal variation, with subordinates preferentially grooming more dominant individuals earlier in the day compared with later in the day. These findings indicate that group-living animals may optimize certain elements of their social strategies over relatively short time periods.
