“…2) as a result of his lack of involvement in play and mutual grooming; a finding also supported by other studies of this species at Edinburgh Zoo (Byrne et al 1983;Young 1998). The behaviour of the parent female and eldest offspring (O1) falls somewhere between that of the parent male and younger juveniles (Fig.…”

“…For example, a population density of 61-63 individuals per kilometre has been reported for C. d. diana in the Tai Forest, West Africa (Buzzard and Eckardt 2007); this is three orders of magnitude more area than most zoo enclosures. Nevertheless, our understanding of within-group wild Diana monkey behaviour is limited; to some extent, this is due to the difficulties of recognising individuals in their natural forest habitat (Byrne et al 1983;Cords 1987). Those studies that followed individuals successfully have shown that wild adult females perform most of the grooming, whereas adults males do not participate in this activity at all (Buzzard and Eckardt 2007), a similar pattern to the C. d. diana studied here.…”

This case study examines the activity budgets of captive Diana monkeys (Cercopithecus diana diana) and discusses results in the context of what is known regarding captive and wild-type behaviour in this species and other guenons. The activities of a family group of Diana monkeys (two parents and four offspring) housed at Edinburgh Zoo, UK, were quantified using a 5-min interval scan sampling technique. The 5100 observation points collected showed that the subjects spent the largest proportion of their time observing (approx. 46%), followed by feeding (approx. 15%), playing (approx. 11%), mutual grooming (approx. 8%) and resting (approx. 7%). The daily activity budgets for each of the subjects were tallied and, at the end of the 10-day observation period, used to produce a data matrix consisting of nine behaviour variables per subject. Clear among-individual differences in activity were identified with canonical discriminant function analysis. This multivariate approach illustrated how the combined behaviours of the parent male were distinct from those of the rest of the family group. Within the remainder of the group, the three youngest offspring displayed similar activity budgets, whereas the overall behaviour of the eldest offspring (a female) was between that of its siblings and her mother.

Finger length ratios (2D:4D) in anthropoids implicate reduced prenatal androgens in social bonding

The second-to-fourth digit ratio (2D:4D) has been proposed as a biomarker reflecting prenatal androgen effects (PAE), such that individuals with lower ratios have experienced higher PAE than those with higher ratios. 2D:4D has been correlated with a number of sex-linked traits in humans such as aggression, promiscuity, and competitiveness. In addition, polygynous societies reportedly have lower 2D:4D (higher PAE) than more monogamous populations. This evidence suggests that PAE may be implicated in the development of sexually selected behaviors in humans. To place 2D:4D research into a broader context, we test the relationship between digit ratios and behavior across nonhuman anthropoids; polygynous species, with higher levels of intrasexual competition, should have more pronounced markers of PAE (lower 2D:4D) than pair-bonded species. Our results accord with those found in humans: 2D:4D is lower in polygynous species and higher (lower PAE) in pair-bonded species. Old World monkeys have low, and relatively invariant 2D:4D (high PAE), which is coupled with high levels of intrasexual competition. This contrasts with higher and more variable ratios in both great apes and New World monkeys. In addition, both male and female ratios decrease with increasing levels of intrasexual competition. Human ratios are intermediate between pair-bonded and more promiscuous hominoids. We propose that PAE may be involved in promoting species characteristic social behavior in anthropoids.

Adult–Adult Play in Primates: Comparative Analyses of its Origin, Distribution and Evolution

2000

Comparative analyses were conducted on a data set derived from the literature so as to test several hypotheses which were developed to explain the distribution of adult–adult play fighting within the order primates. Ratings for play occurring in sexual and non‐sexual contexts were developed. Three hypotheses were evaluated: (i) that play occurring in non‐sexual social contexts is a byproduct of its use in sex; (ii) that the occurrence of play is related to its use for social assessment and manipulation, and so is more likely to be present in species with reduced familiarity between individuals; and (iii) that phylogenetic affiliation influences the likelihood that species within clades engage in play. We used independent contrasts to test the first two hypotheses, and both were significant, with the presence of play in sexual contexts accounting for 14–16% of the variance of play in non‐sexual contexts, and reduced social familiarity accounting for 30–40% of the variance in the occurrence of play in non‐sexual contexts. To test the third hypothesis, we mapped the occurrence of both types of play onto known phylogenies. The overlap was not congruent, indicating that phylogenetic relationships did not account for the distribution of play. Given that play in both sexual and non‐sexual contexts was more likely to occur in species with a social organization involving reduced frequency of contact between the sexes and other social group members, we suggest that the likely adaptive value of play fighting is as a tool for social assessment and manipulation. The possible factors that mitigate the use of play fighting for these purposes, such as the availability of other forms of communication that could serve similar functions, are discussed.
