The ties that bind: genetic relatedness predicts the fission and fusion of social groups in wild African elephants
TLDR
It is found that genetic relatedness predicted group fission; adult females remained with their first order maternal relatives when core groups fissioned temporarily, and relatedness also predicted temporary fusion between social groups.
Social Bonds of Female Baboons Enhance Infant Survival
TLDR
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.
Queuing and queue-jumping: long-term patterns of reproductive skew in male savannah baboons, Papio cynocephalus
TLDR
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) II. Variation in the quality and stability of social bonds
TLDR
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.
Social relationships among adult female baboons (papio cynocephalus) I. Variation in the strength of social bonds
TLDR
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.
TLDR
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
TLDR
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.
Social networks predict gut microbiome composition in wild baboons
TLDR
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.
True paternal care in a multi-male primate society
TLDR
It is shown that adult males differentiate their offspring from unrelated juveniles and selectively support their offspring in agonistic disputes, and this can be considered true parental care.
