Observational study of behavior: sampling methods.
- J. Altmann
Seven major types of sampling for observational studies of social behavior have been found in the literature and the major strengths and weaknesses of each method are pointed out.
Baboon mothers and infants
- J. Altmann
When it was originally released in 1980, Jeanne Altmann's book transformed the study of maternal primate relationships by focusing on motherhood and infancy within a complex ecological and…
Social Bonds of Female Baboons Enhance Infant Survival
16 years of behavioral data are presented, which demonstrate that sociality of adult females is positively associated with infant survival, an important component of variation in female lifetime fitness.
Social relationships among adult female baboons (Papio cynocephalus) II. Variation in the quality and stability of social bonds
This work draws on data derived from a 16-year study of baboons living in seven different social groups in the Amboseli basin of Kenya to evaluate the quality and stability of social bonds among females, and demonstrates that the quality of social Bonds directly affects their stability.
Queuing and queue-jumping: long-term patterns of reproductive skew in male savannah baboons, Papio cynocephalus
Long-term results provide strong support for the proposition that this variance within this single population of baboons is not an artefact of methodological differences between short-term studies, but is due to true variance in the extent to which high-ranking males are able to monopolize access to females.
Social relationships among adult female baboons (papio cynocephalus) I. Variation in the strength of social bonds
Testing a number of predictions derived from kin selection theory about the strength of social bonds among adult female baboons suggests that social bonds play a vital role in females’ lives, and the ability to establish and maintain strong social bonds may have important fitness consequences for females.
Behavior predicts genes structure in a wild primate group.

In the first quantitative test of the priority-of-access model among wild primates, the reproductive priority of dominant males was confirmed by molecular genetic analysis, however, the resultant high short-term variance in reproductive success did not translate into equally high long- term variance because male dominance status was unstable.
Mate guarding constrains foraging activity of male baboons
The shorter travel distances and feeding bouts experienced by consorting males may represent important constraints on male foraging activity, and probably result in decreased energy intake during mate guarding.
Foraging in a variable environment: weather patterns and the behavioral ecology of baboons

It is suggested that baboons use a suite of interrelated responses to ecological variability that includes not only changes in activity budgets, but also home-range shifts, changes in the length of the active period, and changes in group size through fissions.
Social networks predict gut microbiome composition in wild baboons
Using shotgun metagenomic data from wild baboons, it is found that social group membership and social network relationships predicted both the taxonomic structure of the gut microbiome and the structure of genes encoded by gut microbial species.
