Do females use their sexual status to gain resource access? Investigating food-for-sex in wolves and dogs

TLDR
This study demonstrates that the food-for-sex hypothesis plays a part in intersexual food sharing in canids, and highlights the role of females in the interaction.

Hormonal Monitoring of Reproductive Status in Monogamous Wild Female Owl Monkeys (Aotus azarai) of the Argentinean Chaco

TLDR
It is shown that fecal samples from A. azarai can be used for monitoring female reproductive status and function, and is the first of its kind on wild female owl monkeys.

Behavioural patterns among female African savannah elephants: the role of age, lactational status, and sex of the nursing calf

TLDR
How behavioural patterns, permitted or limited by age (correlated with size and rank) and reproductive condition, pertain to resource needs in female elephants, in contexts not directly related to survival or starvation avoidance is shown.

Insect-Foraging in Captive Owl Monkeys (Aotus nancymaae)

TLDR
Owl monkeys attempted to capture prey often and it is speculated that the protein and lipid content of captured prey is important for meeting the metabolic demands for growth and reproduction.

When Dads Help: Male Behavioral Care During Primate Infant Development

TLDR
Empirical findings on male care among primate taxa are reviewed, before focusing, in the final section, on the author's own work on paternal care in South American owl monkeys (Aotus spp.), with some suggestions for future studies.

The evolution of food sharing in primates

TLDR
Comparisons provide comparative support for the hypothesis that sharing is “traded” for matings and coalitionary support in the sense that these services are statistically associated and can thus be selected for.

Owl monkeys Aotus spp in the wild and in captivity

TLDR
A truly integrated laboratory–field approach that focuses on certain areas that cannot be examined in only one or the other setting (e.g. reproductive biology, communication, energetics) will offer unique opportunities for synergistic interactions between zoo and field research that will have both intellectual and practical benefits.

Natural cooperators: Food sharing in humans and other primates

TLDR
This work synthesizes available evidence on food sharing in humans and other primates, tracing the origins of offspring provisioning, mutualism, trade, and reciprocity throughout the primate order.

The evolution of pair-living, sexual monogamy, and cooperative infant care: Insights from research on wild owl monkeys, titis, sakis, and tamarins.

TLDR
It is imperative that biological anthropologists establish and follow clear criteria for comparing and combining results from published studies and that researchers, reviewers, and editors alike comply with these standards to improve the transparency, reproducibility, and interpretability of causal inferences made in comparative studies.

Food transfers to young and mates in wild owl monkeys (Aotus azarai)

TLDR
Five groups of socially monogamous owl monkeys in Formosa, Argentina were observed to determine the pattern of food sharing under natural conditions and found food that was readily obtained and eaten by all age/sex classes was transferred to young.

Social patterns of food sharing in monogamous owl monkeys

TLDR
This pattern of food sharing between mates in a monogamous species may serve both nutritional and social functions that differ from those in polygamous species.

Courtship feeding increases female reproductive success in bushcrickets

TLDR
Results are reported of an experiment which shows that feeding on the spermatophore enhances the reproductive success of female bushcrickets by increasing the numbers and size of eggs produced.

Regurgitative food transfer among wild wolves

TLDR
Although individuals regurgitated up to five times per bout, the overall ratio of regurgitations per bout was 1.5, and the relative effort of the breeding female was correlated with litter size (Kendall's τ = 0.93, P =0.01).

‘Friendship’ for fitness in chimpanzees?

TLDR
This proposal that primates trade social services for fitness benefits in their relationships with the opposite sex is tested in a colony of captive chimpanzees by examining behavioural data on grooming, agonistic support and food sharing in relation to genetically established paternity.

Maternal food restriction delays weaning in the guinea pig, Cavia porcellus

Why do chimpanzees hunt and share meat?

TLDR
Although several factors are likely to affect chimpanzee hunting decisions and meat sharing, results indicate that primary causes will not be found through invoking simple energetic or reproductive considerations.

Courtship feedings, copulations and paternity in common terns, Sterna hirundo

TLDR
High food availability, as indicated by low tide, was associated with high levels of courtship feeding and few copulations, and vice versa, and the numbers of both were negatively correlated with laying date, suggesting that late breeding was a consequence of poor-quality males unable to provision their females adequately.
