We present results of a 10-year study of free-ranging gray-footed chacma baboons (Papio ursinus griseipes) in the Okavango Delta of Botswana. The majority of deaths among adult females and juveniles were due to predation, while infants were more likely to die of infanticide. There were strong seasonal effects on birth and mortality, with the majority of conceptions occurring during the period of highest rainfall. Mortality due to predation and infanticide was highest during the 3-mo period when… 
Reproduction, Mortality, and Female Reproductive Success in Chacma Baboons of the Okavango Delta, Botswana
TLDR
Data is presented on reproduction, mortality, and female reproductive success from a 10-year study of free-ranging chacma baboons in the Okavango Delta of Botswana and the influence of predation, infanticide, and dominance rank is examined.
Determinants of Reproductive Performance Among Female Gray-Cheeked Mangabeys (Lophocebus albigena) in Kibale National Park, Uganda
TLDR
The results show broad similarities between arboreal, forest-dwelling gray-cheeked mangabeys and their more terrestrial, open habitat- dwelling papionin relatives in the importance of dominance rank in estrous cycle initiation, first reproduction, and reproductive aging.
Seasonal patterns of infant mortality in wild Sanje Mangabeys, Cercocebus sanjei
TLDR
The distribution of infant mortality for one of the world’s most threatened primates, the Endangered Sanje mangabey, Cercocebus sanjei, endemic to the Udzungwa Mountains, Tanzania is examined and tick-borne disease is suggested to be a factor impacting infant mortality and may be interacting with a decrease in nutritional intake during the early dry season.
Factors Influencing the Reproductive Success of Female Black Howlers (Alouatta pigra)
TLDR
Female black howlers may still accrue higher reproductive success through their daughters due to differences between sexes in survival, even if the production of daughters reduces reproductive output due to longer IBIs.
The effect of new alpha males on female stress in free-ranging baboons
Infant Mortality in Black-and-Gold Howlers (Alouatta caraya) Living in a Flooded Forest in Northeastern Argentina
TLDR
The results indicate that infant mortality in Alouatta caraya is affected by several factors—natural disasters, maternal condition and food availability, infanticide after male replacement, and possibly disease and predation—each of which needs to be evaluated to understand the history and demography of this primate population.
Life History of Cercopithecus mitis stuhlmanni in the Kakamega Forest, Kenya
TLDR
Comparative data from wild populations are necessary to understand the evolution of primate life history strategies and differences in life history “speed” between blue monkeys and their close relatives seem to be related to lower juvenile and adult mortality in forests relative to more open habitats.
The ecology of conception and pregnancy failure in wild baboons
TLDR
Analysis of female reproductive cycles from multiple baboon groups in the Amboseli basin between 1976 and 2004 indicates that in a highly variable environment, baboon reproductive success is mediated by the interaction between proximate ecological conditions and individual demographic factors.
FACTORS MEDIATING INTER-GROUP ENCOUNTERS IN SAVANNAH BABOONS (PAPIO CYNOCEPHALUS URSINUS)
TLDR
Results supported the hypothesis that male behavior functions to prevent extra-group males from gaining access to sexually receptive females in chacma baboons in the Okavango Delta, Botswana.
Evolutionary determinants of non-seasonal breeding in wild chacma baboons
TLDR
Investigation of the evolutionary determinants of non-seasonal breeding in a wild primate, the chacma baboon, finds strong support for an effect of reproductive asynchrony modulated by rank, weakening the intensity of reproductive seasonality at the population level.

DO FEMALE CHACMA BABOONS COMPETE FOR A SAFE SPATIAL POSITION IN A SOUTHERN WOODLAND HABITAT
TLDR
It is suggested that the higher-ranking females may be better protected from predation, through access to more central spatial positions in the troop, and a positive correlation was found between a female's dominance rank and the time spent next to other adult troop members.
Reproduction in wild female olive baboons
TLDR
Evaluating several factors that influence female reproduction in a large troop of wild olive baboons found that dominance rank did not influence sex ratio at birth, infant survival in the first 2 years, or adult female mortality.
Eight‐year study of social and ecological correlates of mortality among immature baboons of Mikumi National Park, Tanzania
TLDR
The sociodemographic results are consistent with Wasser's hypothesis that cooperative attacks of female baboons upon other troop females suppress the others' reproduction and the vitality of their infants, thereby improving the relative competitive position of the attackers' own young.
THE STRUCTURE OF SOCIAL RELATIONSHIPS AMONG FEMALE SAVANNA BABOONS IN MOREMI RESERVE, BOTSWANA
TLDR
The effects of maternal kinship, reciprocity, and dominance rank on the social relationships of female baboons in a well-habituated, free-ranging group in the Okavango Delta of Botswana are examined.
FACTORS MEDIATING INTER-GROUP ENCOUNTERS IN SAVANNAH BABOONS (PAPIO CYNOCEPHALUS URSINUS)
TLDR
Results supported the hypothesis that male behavior functions to prevent extra-group males from gaining access to sexually receptive females in chacma baboons in the Okavango Delta, Botswana.
The adaptive value of ‘friendships’ to female baboons: experimental and observational evidence
TLDR
Both observations and experiments suggest that the benefits of friendships to females derive from the protection of their infants against infanticide.
Vulnerability to predation in baboon populations
This study investigates patterns of predation in Papio baboon populations across Africa. Using anecdotal reports collated from the primate and predator literature, the following analyses are
Life history and the competitive environment: trajectories of growth, maturation, and reproductive output among chacma baboons.
TLDR
Using demographic and weight data from this wild population of chacma baboons, five main findings emerged: weight for age and growth rate of infant and juvenile females are positively associated with maternal rank, and male growth is not influenced by maternal rank.
Reproductive constraints on aggressive competition in female baboons
TLDR
It is reported here that high-ranking female baboons at Gombe National Park, Tanzania, enjoy shorter interbirth intervals, improved infant survival, and accelerated maturation of their daughters, but these advantages are countered by a significantly higher probability of miscarriage, and a proportion of high- ranking females suffer from reduced fertility.
Predatory behavior of crowned hawk-eagles (Stephanoaetus coronatus) in Kibale National Park, Uganda
TLDR
Results indicate that primates form the vast majority of all prey items and that a non-trivial fraction of the entire primate population at Ngogo succumbs to crowned hawk-eagle predation each year.
