Reproductive maturation in a sample of captive male baboons.
Though baboons have been considered an appropriate non-human primate model for studying human reproductive and endocrine development. the overall similarity of reproductive maturation between the two species is unclear. This paper examines the role of testicular and adrenal hormones for pubertal changes in a cross-sectional sample of 21 captive male savanna baboons. Morphometric and hormonal in...
متن کاملTestosterone positively associated with both male mating effort and paternal behavior in Savanna baboons (Papio cynocephalus).
Testosterone (T) is often positively associated with male sexual behavior and negatively associated with paternal care. These associations have primarily been demonstrated in species where investment in paternal care begins well after mating activity is complete, when offspring are hatched or born. Different patterns may emerge in studies of species where investment in mating and paternal care ...

متن کاملPrimate model offers insights into male bonding in complex societies.
Primatological research is often conducted for the purpose of clarifying the evolutionary trajectories of behavioral and morphological characters that are either unique to humans or are shared with closely related species. Nonhuman primate species—especially those whose common ancestry is relatively recent, such as chimpanzees—can serve as referential models that provide insights into our evolu...
متن کاملInter- and Intrahabitat Dietary Variability of Chacma Baboons (Papio ursinus) in South African Savannas Based on Fecal dC, dN, and %N
Baboons are dietary generalists, consuming a wide range of food items in varying proportions. It is thus difficult to quantify and explain the dietary behavior of these primates. We present stable carbon (dC) and nitrogen (dN) isotopic data, and percentage nitrogen (%N), of feces from chacma baboons (Papio ursinus) living in two savanna environments of South Africa: the mountainous Waterberg re...
