“…After parturition, concentrations of fGC in the post-partum Amboseli females returned to the levels of cycling females (see also Beehner et al, 2006a; for similar decline in other primates see e.g. Bahr et al, 1998;Bardi et al, 2003;Ziegler et al, 1995). The marked individual differences we detected in fGC levels can arise from a range of genetic and ontogenetic sources that are beyond the scope of the present study; elucidating those will require a focused investigation in itself.…”

Environmental stressors impact physiology and behavior in many species of animals. These effects are partly mediated through changing concentrations of glucocorticoids, which also vary with reproductive state and social conditions. Prior research has focused largely on seasonal breeders, but the close temporal linkage between season and reproductive state in these species hinders ability to disentangle environmental effects from those of the animal's reproductive status. Here we assessed the effects of environmental challenges on the fecal glucocorticoid (fGC) levels of non-seasonal breeders, female baboons (Papio cynocephalus) of Amboseli, Kenya. Amboseli is characterized by a long dry season, during which food and water become scarce, and by extreme temperatures above 40°C in the shade during some months of the year. We found that after accounting for female reproductive status and individual variability, females exhibited higher fGC levels during the dry season than during the wet season. Further, during the wet season, fGC levels were higher in months of high average daily maximum temperatures. During the dry season, fGC levels were elevated both in hotter months and in months during which the baboons spent a relatively high proportion of time feeding. In spite of these stressors, female baboons reproduce during all months of the year in Amboseli, unlike most other mammals in this environment. This may be attributable to their extreme adaptability, specifically their diversified diet, and their ability to modify their behavior, including their activity profiles.

“…The only female that showed an increase in cortisol during the Trio condition was the female with a prolonged period of ovarian inactivity, possibly indicating that this infertility was stress-induced. On the other hand, it is possible that the decline in cortisol concentrations exhibited by the majority of females was due to the decline in E1C, given the evidence for other callitrichids that oestrogen activity promotes cortisol secretion (Saltzman et al, 1994b;Ziegler and Sousa, 2002;Ziegler et al, 1995). However, in the current study, Goeldi's monkey cortisol concentrations remained low also after the females started cycling again.…”

ABSTRACTWe examined variation in glucocorticoid levels in the mandrill, a brightly coloured primate species, to identify major social influences on stress hormones, and investigate relationships among glucocorticoid levels, testosterone and secondary sexual ornamentation. We collected a total of 317 fecal samples for 16 adult male mandrills over 13 months, including mating and non-mating periods and periods of both dominance rank stability and instability, and compared fecal glucocorticoid levels with dominance rank, rank stability, presence of receptive females, gastro-intestinal parasite infection, fecal testosterone and facial red coloration. Glucocorticoid levels did not vary systematically with dominance rank, but increased when the dominance hierarchy was unstable, and increased in the presence of receptive females. The relationship between dominance rank and glucocorticoid levels changed direction according to the stability of the dominance hierarchy: glucocorticoid levels were higher in subordinate males under stable conditions, but under conditions of instability higher ranking males had higher glucocorticoid levels.The influence of dominance rank also interacted with the presence of receptive females:glucocorticoids were higher in dominant males than in subordinates, but only during mating periods, suggesting that dominant males are more stressed than subordinates during such periods. These findings support previous studies showing that the relationship between glucocorticoids and dominance rank in male baboons is dependent on the social environment. We also found that males with higher glucocorticoids suffered a higher diversity of gastrointestinal parasite infection, in line with evidence that glucocorticoids suppress the immune system in other species. However, we found no support for the 3 stres...
