The effect of aggressive competition over food resources on energy intake rate is analyzed for individuals of three groups of 25–35 white-faced capuchin monkeys, Cebus capucinus, living in and near Lomas Barbudal Biological Reserve, Costa Rica. An individual’s energy intake rate on a given food species was affected by its rank and the number of agonistic interactions within the feeding tree. Dominant group members had higher energy intake rates relative to subordinate group members whether or… 
Dominance rank differences in the energy intake and expenditure of female Bwindi mountain gorillas
TLDR
It is suggested that contest competition may be occurring with both fruit and nonreproductive plant parts, which would be consistent with growing evidence that nonre productive plant parts can be contestable.
Food abundance affects energy intake and reproduction in frugivorous female Assamese macaques
TLDR
It was found that an increase in food availability had a positive effect on female energy intake and conception rates, and neither energy intake rates nor activity budgets were influenced by female dominance rank, even during periods when the levels of contest competition were predicted to be high.
Predictors of food-related aggression in wild Assamese macaques and the role of conflict avoidance
TLDR
Analysis of feeding competition at the level of individual food patches in wild Assamese macaques suggests that by increasing feeding tolerance, social bonds may enhance resource acquisition, reduce the risk of injuries and lower levels of agonism-related stress.
Quadratic relationships between group size and foraging efficiency in a herbivorous primate
TLDR
The results indicate that intermediate sized groups had the lowest foraging efficiency and provide a new twist on the growing evidence of non-linear relationships between group size and foraging Efficiency in primates.
Dietary Profile, Food Composition, and Nutritional Intake of Female White-Faced Capuchins
TLDR
Results show that fruit contributed most to overall energy gain despite females devoting a greater proportion of foraging time to invertebrates, and revealed that there are times during low-fruit seasons in which females do not appear to meet their minimum nutritional requirements.
Proximate mechanisms of contest competition among female Bwindi mountain gorillas (Gorilla beringei beringei)
TLDR
This study provides additional support for the claim that there is variability in how primates respond to the quality and distribution of food resources and that avoidance as a strategy to cope with feeding competition may result in similar skew in energy balance as rank-related aggression.
Within- and between-group feeding competition in Siberut macaques (Macaca siberu) and Assamese macaques (Macaca assamensis)
TLDR
Evidence is found that male food resource defense is an important part of between-group competition in that species, and that females benefit from more males in the group through an increased home range size which increased female reproductive success.
Feeding Competition and Agonistic Relationships Among Bwindi Gorilla beringei

TLDR
Feed competition and the resulting female social relationships in mountain gorillas of Bwindi Impenetrable National Park, Uganda, are examined, finding agonistic relationships among females are largely similar in the 2 populations and are best characterized as dispersal individualistic.

TLDR
The impact of aggresive competition on food intake at all the resources used is analysed for every member of a group of brown capuchin monkeys in the Manu National Park, Peru.
Food Competition in Brown Capuchin Monkeys (Cebus Apella): Quantitative Effects of Group Size and Tree Productivity
TLDR
It is suggested that the upper limit to group size is set by the daylength available for foraging in large groups, which is substantially greater than the 4% gain in mean food intake that large groups achieve by displacing smaller groups from fruit trees.
Dominance and feeding competition in captive rhesus monkeys
TLDR
The effects of dominance on reproductive performance appeared to be less related to food intake than to competitive and aggressive interactions, potentially resulting in higher levels of stress for subordinates.
Feeding competition among female olive baboons, Papio anubis
TLDR
The intensity of feeding competition, as measured by supplant rates and spatial clustering of individuals, increased during the dry season, a period of low food availability, seemingly because foods eaten then were more clumped in distribution than those eaten in the wet season.
Sociospatial mechanisms of feeding competition in female olive baboons, Papio anubis
TLDR
It is concluded that both active supplanting and individuals' spatial positions within the group mediate rank-related differences in food intake.
Scramble and Contest in Feeding Competition Among Female Long-Tailed Macaques (Macaca Fascicularis)
TLDR
It is concluded that both components of feeding competition exist in long-tailed macaques, but that contest for food is often transferred into contest for safety and a framework is proposed to relate interspecific variation in contest effects to food distribution and group cohesion.

TLDR
Sexual dimorphism offered the best explanation of sex differences in the diet and foraging behavior of C. capucinus, accurately predicting that males do more strenuous foraging activity, make less use of small foraging supports, and spend more time on or near the ground.

TLDR
The present study on wild female Japanese macaques revealed the occurrence of within-group feeding contest competition for their main winter food item, seeds of Zelkova serrata, and showed that the rank-related difference in feeding behaviour increased when available ZelKova patches were small relative to the area of group dispersion.
Feeding behavior of yellow baboons (Papio cynocephalus): relationship to age, gender and dominance rank.
TLDR
Application of the Kaplan-Meier (1958) statistical procedure to data on feeding bout duration showed that the reduction in expected bout duration due to disruptive social factors was proportionately greater among low ranking individuals than among higher ranking individuals.
FEEDING BEHAVIOR, FLOCK-SIZE DYNAMICS, AND VARIATION IN SEXUAL SELECTION IN CROSSBILLS
TLDR
Differences in rates of agonistic interactions, which influence female feed- ing rates compared with male feeding rates, and likely have a differential effect on female mortality rates and the population sex ratio are suggested.
