Kin recognition by paternal half‐siblings in captive Papio cynocephalus
Our objective in this study was to evaluate whether a group of paternally related, subadult baboons (Papio cynocephalus) would preferentially interact with kin or nonkin when they had been raised apart from kin other than their mothers. Subjects and their mothers were removed from the breeding group and placed in alternate housing within 24 h after birth to ensure that the subjects would not have a social history with either their sire or their h…

Conditioned exercise method for use with nonhuman primates
The objective of this study was to demonstrate the feasibility of using appetitive methods to train adult male olive baboons ( Papio cynocephalus anubis ), who were socially housed and fitted with indwelling catheter/ transducer systems, to exercise on an inclined, motorized, moving treadmill. All subjects were first trained to walk on a motorized treadmill for 30 min at a speed of approximately 1.6 km/hr on a 0 grade. Upon completion of initial …
Assessing the effects of social environment on blood pressure and heart rates of baboons
The objective of this publication is to report on the feasibility of using a tether system for obtaining data on blood pressure and heart rates of socially housed primates and to evaluate the extent to which housing environment alters cardiovascular responses (mean arterial blood pressure and heart rate). Blood pressure and heart rates of adult male baboons ( Papio cynocephalus hamadryas ) were evaluated over a 6 week period under three different…
Neonatal nutrition and longitudinal growth in baboons
This paper reports the results of a 5 year longitudinal experiment that (1) examined growth in adiposity of a group of 48 clinically normal olive savannah baboons ( Papio cynocephalus anubis ) who were randomly assigned at birth to one of three diet treatments that differed, during the first 16 weeks, in the amount of nutrients they provided; (2) tested the hypothesis that different amounts of food availability during the neonatal period (birth t…
Allogrooming, partner choice, and dominance in male anubis baboons
This study was designed to test the hypothesis that among unrelated male baboons ( Papio cynocephalus anubis ) in single‐gender social groups there is no significant association between dominance status and allogrooming performance. The hypothesis was tested using behavioral measures obtained by focal animal sampling techniques. The results indicate that unrelated male baboons established well‐defined linear dominance hierarchies, formed allogroo…
Formula‐fed and breast‐fed baboons
The objective of this study was to compare the immediate and long‐term effects of type of infant diet (formula‐fed vs. breast‐fed) on the weight growth of baboons. Longitudinal (serial) weight data were collected from 44 savannah baboons ( Papio cynocephalus anubis ) for the total preadult period of growth from birth to approximately 8 years of age. Fifty percent of the sample (11 females and 11 males) were fed a standard infant formula by a nurs…
Neonatal nutrition and longitudinal growth from birth to adolescence in baboons
Clinically normal baboons ( Papio cynocephalus anubis [Kingfjdon, 1971]) were used in an experiment which (1) examined growth in 48 subjects randomly assigned to three diet treatments (LC = low calorie; MC = medium calorie; HC = high calorie); (2) tested the hypothesis that different amounts of caloric availability during the neonatal period (birth to 16 weeks) had a significant effect on growth and development as measured by weight, crown‐rump l…

Scratching, dominance, tension, and displacement in male baboons
This paper reports a study designed to test the hypothesis that a relationship exists among dominance rank, tension, and scratch behaviors in anubis baboons ( Papio cynocephalus anubis ). Our study was conducted on two groups of male baboons, each containing eight unrelated individuals who were approximately 6 years of age and who shared common rearing histories. Focal animal sampling was used to collect behavioral data. Hand scratching, foot scr…
Body composition in baboons
The objective of this study was to determine whether noninvasive morphometric measurements of olive baboons ( Papio cynocephalus anubis ) can reliably predict lean body mass and fat mass in this species. Crown‐rump length, triceps circumference, and skinfold measures at the neck, subscapular, suprailiac, and triceps sites were obtained prior to necropsy from 21 clinically normal infant baboons at 18 weeks of age and from 22 clinically normal adol…
Principal components analysis of physical growth in savannah baboons
Morphometric data collected from 118 male and 169 female savannah baboons ( Papio cynocephalus anubis ) aged between birth and 5.5 years were analyzed to describe the morphology and physical growth of this species. Measurements included weight, crown‐rump length, triceps circumference, and skinfolds at the neck, subscapular, suprailiac, and triceps anatomical sites. Principal components analyses were applied to the data to provide multivariate as…
Age changes in affinitive behaviors of baboons
The behavioral development of 96 baboons was systematically recorded from birth to 84 months of age. Eight behaviors were selected as criteria for examining the effects of early rearing experiences (mother‐peer vs peer‐peer), gender, age, and cohort as possible sources of variance in the development of affinitive behaviors of this species. Stepwise multiple regression was used to analyze the data and provide quantitative descriptions of the relat…

Social play in differentially reared infant and juvenile baboons ( Papio sp )
Effects of early experience and peer‐group socialization on later play behavior of baboons ( Papio sp) was assessed. The potential for development of sex differences in play behavior in the absence of sex‐role models was of particular concern. Social play of nursery‐reared baboons was contrasted with that of mother‐reared conspecifics during late infancy (6–12 mo) and the late‐juvenile period (36–42 mo). Males played more than did females and inf…
Longitudinal stability in adult status hierarchies among vervet monkeys ( Cercopithecus aethiops )
Status hierarchies were examined in a captive group over a 12‐year period (1968–1979) to establish the stability and structure of vervet monkey dominance relationships. Dyadic records of spontaneous avoid , bite , chase , and supplant behaviors are summarized into a win/lose matrix to produce a rank order of status at the end of each calendar year. The 13,717 agonistic acts tabulated are drawn from both focal and ad lib data. Relative rank is com…
Sequence and age of eruption of deciduous dentition in the baboon ( Papio sp )
A detailed eruption sequence and associated age of eruption for deciduous dentition in baboons ( Papio sp) are presented in this paper. The sequence was determined by evaluation and comparison of the number and kinds of teeth present in nine age cohorts comprising the study sample of 88 males and 87 females who ranged in age from birth to 763 days. Eruption was assessed visually as present or absent. Several statistical methods used to derive the…

Effects of rearing on aggression and subordination in papio monkeys
The objective of this study is to assess the effects of short‐term maternal deprivation (birth to 12 weeks) followed by peer group rearing on the development of aggressive and subordinate behaviors in papio monkeys (superspecies – Papio cynocephalus ). Nursery reared monkeys (34 males and 30 females) were compared with mother‐peer reared monkeys (11 males and 12 females) in late infancy (6 to 12 months of age) and at the end of their juvenile sta…
Sexual dimorphism in the activity of olive baboons (Papio cynocephalus anubis) housed in monosexual groups
Variations in Subsistence Activities of Female and Male Pongids
Division of labor" has traditionally been regarded as an exclusively human economic institution. Serious consideration of the possibility that incipient forms of labor division may occur in various primate species has been hampered by the conviction that its present expression and prehistoric origin are linked only to human ancestry and society and that it is therefore not susceptible to cross-species analysis. Now that sex differences in the per…

Social organization and food resource availability in primates
Data obtained during a field study of two species of nonhuman primates ( Alouatta villosa and Ateles geoffroyi ) living in the Tikal National Park in Guatemala are used to suggest an answer to the question: To what extent is the existence of a particular form of social organization (group size, structure, and composition) an indication of the amount of energy in the form of food resources available to animals in a particular habitat? Seven resear…
