“…We used this variable as a rough proxy for perceived social stress (Muller et al, 2007;Emery Thompson et al, 2010;Surbeck et al, 2012), as periods when a female is in oestrus have been shown to be a particularly stressful time for both males and females. Chimpanzee pantgrunt vocalizations are commonly used for the measurement of dominance hierarchies, as they are highly uni-directional indicators of relative dominance among dyads (Goodall, 1986;Muller and Wrangham, 2004).…”

“…Homo sapiens [Wolfram et al, 2011]) and resident males (e.g. Pan paniscus [Surbeck et al, 2012]) and therefore would have been an interesting component to the current study had it been possible. The demographics of our study groups did not allow us to adequately separate the effect of reproductive status from number of males in the group (and potentially other factors unique to zoo B) -an important research goal for future studies.…”

In ring-tailed lemurs, Lemur catta, the factors modulating hypothalamic-pituitary-adrenal (HPA) activity differ between wild and semi-free-ranging populations. Here we assess factors modulating HPA activity in ring-tailed lemurs housed in a third environment: the zoo. First we validate an enzyme immunoassay to quantify levels of glucocorticoid (GC) metabolites in the faeces of L. catta. We determine the nature of the female-female dominance hierarchies within each group by computing David's scores and examining these in relation to faecal GC (fGC). Relationships between female age and fGC are assessed to evaluate potential age-related confounds. The associations between fGC, numbers of males in a group and reproductive status are explored. Finally, we investigate the value of 7 behaviours in predicting levels of fGC. The study revealed stable linear dominance hierarchies in females within each group. The number of males in a social group together with reproductive status, but not age, influenced fGC. The 7 behavioural variables accounted for 68% of the variance in fGC. The amounts of time an animal spent locomoting and in the inside enclosure were both negative predictors of fGC. The study highlights the flexibility and adaptability of the HPA system in ring-tailed lemurs.

“…In this analysis we also tested for the influence on daily fGC levels of some behavioral parameters known to increase cortisol or fGC levels in human and/or non-human primates, i.e. vigilance, aggression, grooming and copulation rates (Arlet et al, 2009;Cheney and Seyfarth, 2009;Girard-Buttoz et al, 2009;Lynch et al, 2002;McFarland et al, 2013;Ostner et al, 2008a;Ray and Sapolsky, 1992;Surbeck et al, 2012;Warm et al, 2008). We also controlled for the number of males in proximity as an approximation of the degree of male-male competition.…”

Mate-guarding is an important determinant of male reproductive success in a number of species. However, it is known to potentially incur costs. The aim of the present study was to assess the effect of mate-guarding on male physiological stress and aggression in long-tailed macaques, a species in which males mate-guard females to a lesser extent than predicted by the Priority of Access model (PoA). The study was carried out during two mating periods on three groups of wild long-tailed macaques in Indonesia by combining behavioral observations with non-invasive measurements of fecal glucocorticoid (fGC) levels. Mate-guarding was associated with a general rise in male stress hormone levels but, from a certain threshold of mate-guarding onwards, increased vigilance time was associated with a decrease in stress hormone output. Mate-guarding also increased male-male aggression rate and male vigilance time. Overall, alpha males were more physiologically stressed than other males independently of mating competition. Increased glucocorticoid levels during mate-guarding are most likely adaptive since it may help males to mobilize extra-energy required for mate-guarding and ultimately maintain a balanced energetic status. However, repeated exposure to high levels of stress over an extended period is potentially deleterious to the immune system and thus may carry costs. This potential physiological cost together with the cost of increased aggression mate-guarding male face may limit the male's ability to mate-guard females, explaining the deviance from the PoA model observed in long-tailed macaques. Comparing our results to previous findings we discuss how ecological factors, reproductive seasonality and rank achievement may modulate the extent to which costs of mate-guarding limit male monopolization abilities.
