Body temperature and physical activity correlates of the menstrual cycle in Chacma Baboons (Papio hamadryas ursinus).
We investigated the temporal relationship between abdominal temperature, physical activity, perineal swelling, and urinary progesterone and estradiol concentrations over the menstrual cycle in unrestrained captive baboons. Using a miniature temperature-sensitive data logger surgically implanted in the abdominal cavity and an activity data logger implanted subcutaneously on the trunk, we measure...
متن کاملOntogenetic Scaling of Fore- and Hind Limb Posture in Wild Chacma Baboons (Papio hamadryas ursinus)
Large-scale interspecific studies of mammals ranging between 0.04-280 kg have shown that larger animals walk with more extended limb joints. Within a taxon or clade, however, the relationship between body size and joint posture is less straightforward. Factors that may affect the lack of congruence between broad and narrow phylogenetic analyses of limb kinematics include limited sampling of (1)...
متن کاملBehavioural and hormonal responses to predation in female chacma baboons (Papio hamadryas ursinus).
In humans, bereavement is associated with an increase in glucocorticoid (GC) levels, though this increase can be mitigated by social support. We examined faecal GC levels and grooming behaviour of free-ranging female baboons to determine whether similar effects were also evident in a non-human species. Females who lost a close relative experienced a significant increase in GC levels in the week...
متن کاملCorrelates of stress in free-ranging male chacma baboons, Papio hamadryas ursinus
In male baboons, social instability is known to increase concentrations of glucocorticoids (GCs), a class of steroid hormones associated with the vertebrate stress response. The stress response may be particularly marked among male chacma baboons, whose social groups often demonstrate a strong mating skew and high rates of infanticide. Here we test this prediction and explore additional correla...
متن کاملFemale–female competition for male ‘friends’ in wild chacma baboons, Papio cynocephalus ursinus
Lactating female chacma baboons, Papio cynocephalus ursinus, maintain close associations, or ‘friendships’, with particular males that may protect infants from sexually selected infanticide by a newly immigrated alpha male. In a 2-year study, we sought evidence of female–female competition for male friends in cases where two mothers maintained friendships with the same male simultaneously. In t...
