Cheap talk when interests conflict
Article Abstract:
The conflict of interest between sender and receiver in animal communication, mans that honest signals must be costly. However it is indicated that low cost signals can be evolutionarily stable. A game theory model that demonstrates how low cost signals can evolve if there are no conflicts of interest was assessed, and an empirical example suggested that female rhesus macaques used honest and low cost vocal signals to facilitate interactions in conflict of interest situations.

Time-matched grooming in female primates? New analyses from two species
Article Abstract:
The gromming partners that will alternate between giving and receiving grooming within grooming bouts, and that each partner will perform approximately as much grooming as it receives within each bout is predicted by the parcelling model of reciprocity. Weighted logistic regression and weighted least-squares regression were used to test this prediction.

Why are infants so attractive to others? The form and function of infant handling in bonnet macaques
Article Abstract:
Alloparental care is common in many species, including primates. A new study investigates patterns of infant handling in a large group of bonnet macaques to test several hypotheses for natal attraction. It is shown that the female macaques in the group were strongly attracted to young infants and suggested that the findings provide evidence that natural selection favours natal attraction because responsive females make good mothers. Details of the study are presented.
