The endocrine stress response and alarm vocalizations in rhesus macaques
Article Abstract:
A study of the endocrinal response of macaques to stressful situations reveals that vocal response and cortisol concentrations are not necessarily linked by a causal connection. The stresses applied were capture, staring at the subject's own elephant and staring at another's infant. A control group with cortisol suppressed was used. Vocal alarms varied with the threat applied, with some reduction in the response of the female macaques with suppressed cortisol levels.

Re-examining the relationship between rank and reproduction in male primates
Article Abstract:
The validity of the Bercovitch-McMillan is defended because of the unnecessary inclusion of male subadults that lead to inflated correlation coefficients. Actually, a re-analysis of the data shows the strength of the said hypothesis, and the misleading results are the product of Type I error. Moreover, in primates, dominance rank is not significantly correlated with reproductive success within the adult male age class.

Dominance rank, reproductive success and reproductive tactics in male primates: a reply to Dunbar and Cowlishaw
Article Abstract:
Type I error may be independent of sample size, but Type II error decreases with an increase in sample size. In line withthis, the inclusion of subadults, which is very different from adults, jeopardizes the statistical process. Moreover, relative dominance rank influences male reproductive tactics, but alternative tactics undermine direct links between rank and reproduction among male primates.
