Are Baboon Infants Sir Phillip Sydney's Offspring?
Data on mother-offspring interactions in chacma baboons (Papio cynocephalus ursinus) were used to test predictions arising from Bateson's (1994) dynamic assessment model of mammalian weaning
This study evaluated the responses of infant Japanese macaques (Macaca fuscata) to their mother's resumption of mating. Mothers and infants were observed before, during and after the mating season.
Genetic aspects of mother-offspring conflict in rhesus macaques
Findings concur with those of recent studies in other animal taxa in suggesting that conflict-related behavioral traits may be genetically correlated in mothers and offspring and that the latter may be engaged in a runaway selection process that would result in the escalation of conflict.
How do male interactions with infants affect mothers and infants in Barbary macaques (Macaca sylvanus)
In a provisioned group of macaques, mothers and infants do not appear to directly benefit from male infant handling but may pay a cost, while Mothers and infants may gain long-term benefits such as agonistic support, access to resources and earlier infant weaning from associated with males in the group.
Mother-infant relationships in baboons (Papio hamadryas): predictors of differences and discontinuities in developmental pathways.
The authors proposed that this can reflect the occurrence of reorganizations or discontinuities in the mother-infant relationship that can be related to important life events such as the mother's resumption of sexual activity.
Maternal investment in mountain baboons and the hypothesis of reduced care
It is argued that factors that influence the maternal strategy adopted by mountain baboons include slow infant growth rates and a lack of predation in the habitat which influences probability of offspring survival beyond the immediate postnatal period.
Food access in captive Ammotragus: the role played by hierarchy and mother–infant interactions
It is concluded that a maternal presence is necessary for aoudad calves to successfully feed from troughs, and that families of higher social rank benefit by getting access to this food source earlier in the day and are disturbed less than low-ranking families.
The meaning of weaning in wild Phayre's leaf monkeys: last nipple contact, survival, and independence.
Overall, in wild (but not in provisioned) Asian colobines, age at last nipple contact was allometrically related to adult female body mass, supporting its designation as a life history variable.
Regularities and diversity in developmental pathways: mother-infant relationships in hamadryas baboons.
Empirical evidence is provided that growth curve analysis can be useful to tackle various hot issues in the study of behavioral development and that infant age was not predictive of the rate of the behaviors relating to the management of mother-infant conflicts.

26 27 An analysis of individuals' behavior when accessing a restricted food source (troughs) 28 was carried out in a captive population of aoudad, Ammotragus lervia. Access to the 29 troughs followed


The Effect of Some Non-Social Factors On Mother-Infant Contact in Long-Tailed Macaques (Macaca Fascicularis)
Mother-infant dyads were studied among wild long-tailed macaques in North Sumatra (Indonesia). The influence of arboreality and mother's immediate activity on physical contact was examined during the
Nutrition, fertility and maternal investment in primates
It is suggested that nutrition of the mother is most important during the early phase of rapid infant growth, because at that time the energetic requirements of lactation are high; and that a mother's ability to assess her infant's demands and needs for nutrition for growth leads to alterations in suckling frequencies which result in variation in female fertility.
Female weight and reproductive condition in a population of olive baboons (Papio anubis)
Results indicate that lactation in wild baboons imposes energy costs that result in lost weight and it is suggested that female baboons may have to surpass a minimum weight threshold prior to resumption of postlactational cycling.
Parent-Offspring Conflict
When parent-offspring relations in sexually reproducing species are viewed from the standpoint of the offspring as well as the parent, conflict is seen to be an expected feature of such relations. In

Baboon mothers and infants
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

Seasonal fluctuations in food availability were closely related to rainfall patterns, with the end of the dry season representing a significant energy bottleneck and Implications of seasonality for baboons.
Reproductive Decisions: An Economic Analysis of Gelada Baboon Social Strategies
Robin Dunbar uses economic models to explore the social behavior of the gelada baboon (Theropithecus gelada), a unique species, whose social system is one of the most complex among the primates. His
