Interbirth intervals in wild baboons: Environmental predictors and hormonal correlates
OBJECTIVES: Interbirth intervals (IBIs) are a key metric of female reproductive success; understanding how they are regulated by environmental, social, and demographic factors can provide insight into sources of variance in female fitness. MATERIALS AND METHODS: Using 36 years of reproductive data on 490 IBIs for 160 wild female baboons, we identified sources of variance in the duration of IBIs and of their component phases: postpartum amenorrhea…

White monkey syndrome and presumptive copper deficiency in wild savannah baboons
In immature wild savannah baboons ( Papio cynocephalus ), we observed symptoms consistent with copper (Cu) deficiency and, more specifically, with a disorder referred to as white monkey syndrome (WMS) in laboratory primates. The objectives of this study were to characterize this pathology, and test three hypotheses that (1) Cu deficiency may have been induced by zinc (Zn) toxicity, (2) it may have been induced by molybdenum (Mo) toxicity, and (3)…
Age and individual foraging behavior predict tooth wear in Amboseli baboons
Teeth represent an essential component of the foraging apparatus for any mammal, and tooth wear can have significant implications for survival and reproduction. This study focuses on tooth wear in wild baboons in Amboseli, southern Kenya. We obtained mandibular and maxillary tooth impressions from 95 baboons and analyzed digital images of replicas made from these impressions. We measured tooth wear as the percent dentine exposure (PDE, the percen…
Endocrinology of year‐round reproduction in a highly seasonal habitat: Environmental variability in testosterone and glucocorticoids in baboon males
In conditions characterized by energetic constraints, such as in periods of low food availability, some trade‐offs between reproduction and self‐maintenance may be necessary; even year‐round breeders may then be forced to exhibit some reproductive seasonality. Prior research has largely focused on female reproduction and physiology, and few studies have evaluated the impact of environmental factors on males. Here we assessed the effects of season…
Remote monitoring of primates using automated GPS technology in open habitats
Automated tracking using a satellite global position system (GPS) has major potential as a research tool in studies of primate ecology. However, implementation has been limited, at least partly because of technological difficulties associated with the dense forest habitat of many primates. In contrast, primates inhabiting relatively open environments may provide ideal subjects for use of GPS collars, yet no empirical tests have evaluated this pro…
Parallel effects of genetic variation in ACE activity in baboons and humans
Like humans, savannah baboons ( Papio sp.) show heritable interindividual variation in complex physiological phenotypes. One prominent example of such variation involves production of the homeostatic regulator protein angiotensin converting enzyme (ACE), which shows heritable variation in both baboons and humans. In humans, this phenotypic variation is associated with an Alu insertion–deletion polymorphism in the ACE gene, which explains approxim…

Coming of age: Steroid hormones of wild immature baboons ( Papio cynocephalus )
Large gaps exist in our knowledge about common patterns and variability in the endocrinology of immature nonhuman primates, and even normal hormonal profiles during that life stage are lacking for wild populations. In the present study we present steroid profiles for a wild population of baboons ( Papio cynocephalus ) from infancy through reproductive maturation, obtained by noninvasive fecal analyses. Fecal concentrations of glucocorticoid (fGC)…
Life‐history correlates of steroid concentrations in wild peripartum baboons
Steroid concentrations during late pregnancy and early lactation may be affected by both a female's reproductive history and her current condition, and may in turn predict subsequent life‐history events, such as offspring survival. This study investigated these relationships in a wild primate population through the use of fecal steroid analysis in repeated sampling of peripartum baboons ( Papio cynocephalus ). Fecal samples were collected from 32…
Social Bonds of Female Baboons Enhance Infant Survival
Among nonhuman primates, females often form strong bonds with kin and other group members. These relationships are thought to have adaptive value for females, but direct effects of sociality on fitness have never been demonstrated. We present 16 years of behavioral data from a well-studied population of wild baboons, which demonstrate that sociality of adult females is positively associated with infant survival, an important component of variatio…
Variability in reproductive success viewed from a life‐history perspective in baboons
Nonhuman primates, like humans, mature slowly and have low fertility during a relatively long life. As data have accumulated on life-history patterns of nonhuman primates, comparative studies have yielded important insights into the evolution of this slow life-history style of primates. However, in order to understand selection pressures and evolutionary potential within species, it is important to complement comparative studies with detailed stu…
Effects of food availability on serum insulin and lipid concentrations in free‐ranging baboons
The relationship between food availability and metabolic physiology was studied in groups of free‐ranging baboons ( Papio spp.) living in the Amboseli National Park and the Masai Mara National Reserve of Kenya. Three groups subsisted entirely on natural forage, while two other groups lived near tourist facilities and often consumed food wastes from these lodges. The refuse provided a very accessible food source with relatively high caloric densit…
Information content of female copulation calls in yellow baboons
In a wide variety of animal species, females produce vocalizations just before, during, or immediately after copulation. Observational and experimental evidence indicates that these copulation calls are sexually selected traits, functioning to promote competition between males for access to the calling female. In this paper, we present an acoustic analysis of variation in the form of copulation calls of female yellow baboons, Papio cynocephalus c…
Immigration and hybridization patterns of yellow and anubis baboons in and around Amboseli, Kenya
In 1986, Samuels and Altmann reported evidence for a hybrid zone between Papio anubis and Papio cynocephalus in Amboseli, Kenya, in a baboon population that has been the subject of long‐term study since 1971 [Samuels & Altmann, International Journal of Primatology 7:131–138, 1986]. In the current report we document ongoing patterns of hybridization in Amboseli between anubis and yellow baboons. In July 2000, we exhaustively scored living members …

Cross‐species amplification, non‐invasive genotyping, and non‐Mendelian inheritance of human STRPs in Savannah baboons
Twenty-nine human microsatellite primer pairs were screened for their utility in the cross-species amplification of baboon DNA derived from both blood and feces as part of a larger study to identify paternal half sisters in a population of wild baboons (Papio cynocephalus). Forty-one percent (12/29) of the human primers successfully amplified baboon DNA. Of these 12 primers, six amplified fragments that were both polymorphic and heterozygous (mea…

Balancing Costs and Opportunities: Dispersal in Male Baboons
Young male baboons typically disperse from their group of birth as they near adult size and may continue to migrate between social groups throughout their lives. Long-term data on dispersal and residence patterns of male baboons in Amboseli National Park, Kenya, were available for 110 males in the population, including 43 that were monitored during their natal dispersal. These data enabled us to provide not only a detailed evaluation of the effec…

Periodontal health in free‐ranging baboons of Ethiopia and Kenya
Frontal and lateral intraoral photographs of 19 baboons from the Awash National Park, Ethiopia and 37 baboons from Amboseli National Park, Kenya, were used to assess periodontal health. The Awash baboons, and two groups (Alto's and Hook's) at Amboseli, fed entirely from natural sources, but baboons from the third Amboseli group (Lodge) fed largely on food refuse from one of the park's lodges. Juveniles and adults were evaluated separately. Intrao…

Physical maturation and age estimates of yellow baboons, Papio cynocephalus , in Amboseli National Park, Kenya
In a longitudinal study of individually identified wild baboons in Amboseli National Park, Kenya, we collected data on physical development and reproductive maturation. Confirming and extending our earlier results, we demonstrated that the ratio of ages at which developmental milestones occur in the field as compared to those under extensive provisioning or in captivity were approximately 5:3. The age range for some developmental milestones was q…
Demography of Amboseli baboons, 1963–1983
Repeated censuses of a population of yellow baboons ( Papio cynocephalus ) in Amboseli National Park, Kenya, revealed a decrease from over 2,500 animals in 1963–1964 to 123 individuals in 1979, or from a density of about 73 to 1.8 baboons per km 2 over a 15‐year period. Median group size decreased from 43 in 1964 to 27 in 1979. The largest and smallest groups declined the most; groups near the median have maintained fairly stable size and age dis…

Fatal intragroup kidnapping in yellow baboons
The fatal kidnapping of a 5‐day‐old baboon ( Papio cynocephalus ) in Amboseli National Park, Kenya, is described. Although pulling and rough handling of primate infants by nonmothers are frequently observed, records of fatal intragroup kidnappings are rare. In the instance described here, the mother, a healthy, primiparous female, did not retrieve the infant from the kidnapper, a higher‐ranking juvenile female of the same group, until he died 3 d…
Differences in daily life between semiprovisioned and wild‐feeding baboons
Activity budgets and social aspects of feeding, among the adult females in a group of semiprovisioned baboons that fed from a garbage dump were compared with those of adjacent wild‐feeding groups in Amboseli National Park, Kenya, during the dry seasons of 1984 and 1985. Statistically significant differences were found in time spent feeding, distance travelled, and the relationship between dominance rank and time spent feeding. The garbage‐feeding…

Endocrine and developmental correlates of unilateral cryptorchidism in a wild baboon
A wild, group‐living 8.5‐year‐old adult baboon was found to have only a single palpable testicle, the only case of cryptorchidism found among more than 200 males that we have examined. This young adult had an unusually small body size for his age, one that was comparable to that of immature males two years younger, and during maturation his body mass was increasingly small for his age. As a young adult, he also had very low testosterone concentra…
Methods for analysis of unbalanced, longitudinal, growth data
We describe an approach to analysis of growth that does not depend on assumptions about the underlying functional growth pattern and that allows for multiple observations arising from individual‐specific, irregularly spaced data. We produce estimated growth curves for predefined subject groups by using LOWESS, a nonparametric smoothing algorithm. We describe how statistical significance of curve features may be evaluated by using the “jackknife,”…

Body size and fatness of free‐living baboons reflect food availability and activity levels
We used morphometric techniques and isotope‐labeled water to investigate the influence of abundant, accessible food and resultant low activity levels on body size and fatness in free‐living adolescent and adult baboons as compared to animals in the same population that experienced more typical, wild‐feeding conditions. Females that had access to abundant food from a nearby garbage dump averaged 16.7 kg body mass, 50% more than their wild‐feeding …
