While the activation of the infant hypothalamic-pituitary-gonadal (HPG) axis and the existence of a postnatal gonadotrophin surge were first documented in the early 1970s, study of the longitudinal development of gonadal hormones in infancy, and the

Between-group aggression is a common feature of many group-living animals. Yet aggressive behaviors are often costly, involving risk of injury, increased energy expenditure and the potential to reduce feeding time. For aggression to be evolutionarily

Abstract For mammalian males, copulating with females during ovulation is critical to reproductive success. However male knowledge of ovulation may not always be advantageous for females, as it could hinder mate choice or promote harassment. White-fa

The responses of plural breeding mammals to environmental stressors are little understood in free-ranging populations, but recent studies of singular breeders suggest that ecological factors and social milieu influence the variable physiological stre

Potential interactions between age and endocrinological functioning have been understudied in wild ape populations. Therefore, we examined the relationship between age and the secretion of androgens and glucocorticoids in 15 juvenile, subadult, and a

Female baboons (Papio hamadryas spp.) must contend with myriad potential stressors on a daily basis. In a previous study on female chacma baboons, Papio hamadryas ursinus, living in the Okavango Delta of Botswana, increases in glucocorticoid (GC) con

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 simi

To date, research on testosterone and behavior has focused on individuals, even when studying social behaviors that necessarily involve multiple participants. Here, we explore male responses to other males of different dominance ranks and testosteron

As the epidemiological and physiological investigation of isoflavones and lignans expands, the need for sensitive methods for analyzing large numbers of samples intensifies. We have developed a method using high-performance liquid chromatography (HPL

Despite the many benefits that testosterone has on male reproduction, sustaining high levels of testosterone for long periods can be costly. The challenge hypothesis predicts that males will show temporarily sustained elevations of testosterone at cr
