I found this on a research project:

Females' GC levels will rise significantly at the onset of the unstable period.

Three factors suggest that females relied on a focused grooming network as a coping mechanism to alleviate stress.
First, all females' grooming networks become less diverse in the weeks following the initial upheaval.
Second, females whose grooming had already focused on a few predictable partners will show a less dramatic rise in GC levels than females whose grooming network have been more diverse.
Third, females who contracted their grooming network the most experienced a greater decrease in GC levels in the following week.
Conclusion: close bonds with a few preferred partners allow female baboons to alleviate the stress associated with social instability.


Note: I have a close bond with only one partner, but this can still be very, very stressful :roll:

The glucocorticoid levels are linked to the behaviour of the female baboon by increasing in concentration to allow the organism to cope with environmental or social challenges such as a change in the alpha male (Wittig et al. 2008). If these behaviours are successful the GC levels are then lowered preventing harmful effects to the animal such as chronic stress ( Wittig et al. 2008). The activity of grooming is believed to lower these stress levels and is the result of an allostatic process (adjusting to the stress). These grooming interactions or patterns must change during periods of social instability for the theory to be proven correct. In the okavango delta a female baboon aho lost a grooming partner experienced an increase in GC levels and consequently expanded her grooming "network" ie chose more grooming partners. Conversely during periods of stability when grooming networks are intact the GC levels were found to be substantially lower (Wittig et al. 2008). Glucocorticoid levels are linked to behavioural responses and function to reduce the negative impact of stressors, as such when social interactions are stable with well defined social support the psychological stress on the female is reduced and hence lowers GC levels (Engh et al. 2006).

:lol: :lol: I was also perturbed by that, Ods. Then I decided you wanted to bring something to my attention. Hormones. Baboons. Alpha male. You know? :wink: :lol: :twisted: :tongue:

There is growing evidence that some species of wild nonhuman primate, especially chimpanzees, take herbal and clay medicines to treat and prevent disease. Such a primate pharmacopoeia may be a missing link in our understanding of the relationship between primate foraging and ranging strategies and plant chemistry; not all plant secondary compounds may be deleterious to the consumer. Just as study of traditional herbal medicines has yielded powerful drugs, so primate medicines may hint at drugs useful in treating human disease.
